Coal's already on its way out. Nuclear generation was losing ground well before Fukushima. Wind and solar are growing faster than any other form of generation and they don't need fuel in order to keep working.

Maybe there will be a use for a future tech nuke plant, but someone's got to design, build, test, and certify them first. What portion of our energy production needs can they meet by 2050?

I would consider that the reaction to Fukushima isn't just in regard to its effects, but that it easily could have been much, MUCH worse.
Sure, it COULD have been, but what's the likelihood?

Aye, there's the rub. What IS the likelihood? What IS the risk?

Apparently, the nuclear and insurance industries consider the risk too high to bear. That is why Congress passed the Price-Anderson act.

Epidemiological results from past mishaps are not informative as to the actual risk. That would be like conducting an epidemiological study of a pistol that has had the trigger pulled 4 times in a game of Russian Roulette. "No injuries noted…"

Which is why I said that until it's repealed, it won't be possible to convince the U.S. public that reactors are acceptably safe, regardless of how safe they are. Nor should it be attempted prior to repeal - the U.S. nuke lobby needs to put their money where their mouth is, while developing reactors that are truly fail-safe. There's a fair amount of research being done in various places to do that.

However, to dismiss epidemiological results from past mishaps on one hand, while the anti-nuke groups are attributing all sorts of ridiculous levels of injuries/illnesses/deaths (not backed up by the epidemiology) as well as future supposed risks based on those very same past accidents is just a teensy bit dishonest, don't you think? What we know is that even with all the bungling and comparatively unsafe reactor designs that were involved in past accidents, the epidemiology not only from those accidents but also A and H-bomb testing as well as actual use, the risks are still orders of magnitude less to people over the long term than extracting and burning coal. Not infinitesimal risk, which some of the pro-nuke groups have claimed at various times, with equally little basis as the inflated risk claims of the anti-nuke groups. The risks are quantifiable, and while hardly perfect are enough to have a rational discussion of the comparative risk from various technologies.

So you guys see little real difference between contaminating an area with, say, plutonium, and putting soot into the air...? Ok.
On the contrary, I do. The plutonium will harm fewer people. Actually, it's not plutonium that we really need to worry about as far as accidents go, it's all the other by-products, like Cesium, Strontium, Iodine etc. See e.g http://en.wikipedia.org/wiki/Radiation_effects_from_the_Fukushima_Daiichi_nuclear_disaster" onclick="window.open(this.href);return false;

We need to worry about plutonium primarily in terms of proliferation, which is what concerns people about the widespread introduction of fast breeder reactors.

Coal is a long way from disappearing in China, Andy, nor are nukes. To be sure, the newer Chinese coal plants are larger, more efficient and less dirty than many of the older ones they replace, but their numbers and % of power remain huge, and will be at least up to 2050.

As to Nukes,they've got 26 building at the moment to add to the 23 in operation to give them 58GWe by 2020, increasing to 150 GWe by 2030 and more construction planned out until 2050 at least, with 4th gen plants planned to start replacing Gen III/III+ from 2030 or 2040 (can't find the date at the moment). Note that the wiki article on China's plans says that they intend to get 1500GW from Nukes by the end of the century, but I'm not sure where that number comes from: http://en.wikipedia.org/wiki/Electricity_sector_in_China" onclick="window.open(this.href);return false;.

I didn't say coal was 100% absolutely totally dead, Guy, but it's pretty clearly on its way out. Same for current-tech nukes. It appears that China's economy is starting to turn the corner as well (they're outsourcing some of their production) - when the China bubble pops I expect it'll take much of the old-tech with it.

Fingers crossed.

You pointed out some of the purveyors of inaccurate information, but you missed at least one. One of the very significant problems with a reliance on 'epidemiological results' and other bits of data is that the nuclear industry (both weapons and energy) have been keeping two sets of books from the beginning. We can parse the numbers from the 'public' books but it'll lead us in a very different direction and to a very different cost/benefit point.

Just one example: A neighbor of mine for a time was an MD/PhD biomedical researcher (still a doc; no longer a neighbor). She brought her family to the 'States from Moldova to escape the criminal medical cover-up that continues to plague the countries in E Europe after Chernobyl and because her daughter was showing signs of thyroid issues. It's unfortunately quite correct that the stats show few deaths from the disaster. That's only because kids dying of strange cancers have 'cancer' listed as the cause of death, not 'nuclear power.'

According to various whistle blowers, the US nuclear industry's been doing this since the beginning of the nuclear age. Japan's restricting the press and doctors since shortly after Fukushima as well.

Until we can gain access to the full data sets, we cannot judge which form of generation is 'better' or 'worse.'
 
I have a coworker who works in Japan. He and his extended family are from Fukishima about 100 km from the nuclear plant. He sees people slowly forgetting about the disaster and expects the country to be mostly pro nuclear in 10 years.

China decided not to start any more CPR-1000 (Gen II+) reactors in the aftermath of Fukushima, modifying them to CPR-1000+ and ACPR1000 to bring them up close to Gen III safety, and instead concentrate on Gen III like the (Westinghouse-derived) AP1000 and later developments (CAP1000/1400/1700), looking to shift from building PWRs around 2040, with fast reactors increasingly built from 2020 on. The current plan is to start construction on a 1GWe Fast Neutron Reactor in 2017 for operation in 2023, based on the 65MWe demo reactor they've had operating since 2010.

OTOH, 59% of the generating capacity they added in 2012 was mostly if not entirely in new Supercritical and Ultra Super Critical coal plants (and they're working on IGCC), replacing the older, inefficient ones. Aside from the pollution and energy efficiency reasons for doing this, their rail system is maxed out transporting coal from where it's mined to the power plants where it's needed.

They've got similar issues with the need to build transmission lines from the west and north where the wind resources are to where it is needed along the east coast, and interconnects are also lacking so they're still wasting a lot of wind power, which are two of the reasons the U.S. still generated more wind electricity last year despite having less installed wind capacity. I haven't found new coal power plant data for 2013 or 2014 yet, but in 2013 China overtook the U.S. to become #1 in total electrical generating capacity, although not (I think) in production yet:
Total installed capacity in 2013 was 1247 GW.[3]

Coal 801 GW[4]

Other thermal, natural gas, bio-mass 61 GW[5]

Hydropower capacity 280 GW[6]

Wind power capacity was 91.4 GW[7]

Solar power capacity was 18 GW[8]

Nuclear power capacity was 15.69 GW

India is another country with lots of coal (ca. 60% of their electricity), in old, inefficient plants. They've also got two fast breeder reactors operating, in addition to their more conventional ones. We'll have to see how the politics of all that play out, as India's got about 300 million people with no access to electricity, and coal powered electricity would be a health improvement for them compared to all the biomass burned in unhealthy conditions. From the wiki:
Some 800 million Indians use traditional fuels – fuelwood, agricultural waste and biomass cakes – for cooking and general heating needs. These traditional fuels are burnt in cook stoves, known as chulah or chulha in some parts of India.[17][18] Traditional fuel is inefficient source of energy, its burning releases high levels of smoke, PM10 particulate matter, NOX, SOX, PAHs, polyaromatics, formaldehyde, carbon monoxide and other air pollutants.[19][20][21] Some reports, including one by the World Health Organisation, claim 300,000 to 400,000 people in India die of indoor air pollution and carbon monoxide poisoning every year because of biomass burning and use of chullahs.[22] Traditional fuel burning in conventional cook stoves releases unnecessarily large amounts of pollutants, between 5 to 15 times higher than industrial combustion of coal, thereby affecting outdoor air quality, haze and smog, chronic health problems, damage to forests, ecosystems and global climate. Burning of biomass and firewood will not stop, these reports claim, unless electricity or clean burning fuel and combustion technologies become reliably available and widely adopted in rural and urban India.

The organization doing the epidemiological work post Chernobyl was the WHO through UNSCEAR. As it happens, the Ukrainians and Russians agreed to have an American scientist head the project, as they both trusted him but not each other to be objective. The scientists involved were from many countries. Here:
http://www.unscear.org/unscear/en/chernobyl.html" onclick="window.open(this.href);return false;

Feel free to provide peer-reviewed evidence of such a coverup, Andy.

As to other causes of death, yeah, there are a lot of them in the FSU, where what limited environmental and occupational health laws existed were ignored whenever it was expedient (which is to say, routinely), and that's before you even consider that Russian males, in particular, are attempting to drink and smoke themselves to death in large numbers.

A couple of decades ago, I had to take an English class and, looking for some easy credits, chose one because the instructor had been a dual English/Environmental Studies major, and I'd already read most of the books on the reading list, e.g. Walden, Silent Spring, etc. For a final we had to write a paper on some environmental disaster, and rather than doing one on the usual suspects (Chernobyl, TMI, Bhopal, Exxon Valdez etc.) I wanted to go further afield. Fortunately, the college library had a subscription to the Bulletin of the Atomic Scientists, and this was the early '90s when a lot of Soviet scientists involved in their weapons program were starting to talk about their work, which often appeared in the BAS. One incident in particular, which became known as the Kyshtym disaster (and which mirrored concerns about the possibility of a similar accident at Hanford: Chelyabinsk-40 was the Soviet equivalent, plutonium-production reactors for weapons) interested me, so I decided to do the paper describing that accident as well as the general (lack of) safety and environmental practices in the area. If you're not familiar with the accident, see http://en.wikipedia.org/wiki/Kyshtym_disaster" onclick="window.open(this.href);return false;

That article mentions that contaminated water was discharged directly into Lake Kyzyltash; what it doesn't mention (but the BAS articles did) is that at one point, anyone standing on the shore of the lake would receive a lethal dose of radiation in about an hour, and that the lake regularly dried up and the winds would blow silt over a wide area. Chernobyl was bad but it was hardly an aberration, nor was it the sole source of environmental hazard in the FSU, the lands of which were and remain a toxic sewer from numerous sources.

Here's likely the core of the problem. One is not going to find peer reviewed documentation of a coverup when information required to conduct the studies is controlled. Therefore, expecting such before accepting the reality of a thing is a fools errand.

This isn't without precedent. For example - why are elements of the US power structure and some in the intelligence community so angry with Julian Assange and WikiLeaks? Why is Snowden in exile? Why is Manning in Ft Levenworth? Why are there a number of journalists in jail for not revealing their sources? Why doesn't Monsanto release information they're required to generate for their transgenic seeds? Why did the Japanese government quickly implement new secrecy laws after Fukushima that restricts doctors and journalists from writing about what they see?

We talked about this some in the Snowden thread, but as a reminder, the security oath I took years ago binds me until 70 years have passed or until I am dead. By its very nature, controls such as that tend to restrict conversation.

You were able to write about the information you were able to find, but you were not able to write about the information you were not permitted to see. It's best that I leave it there.
 
For advanced nuclear power to be a part of the low-carbon solution, it has to be truly low carbon. I'd very much like to see how rapidly units can be designed/tested/approved/built, and would like to see how they'll be fueled. Past/current nuclear power has consumed the highest grade fuel on the planet - we've entered into a low EROEI phase for uranium as we have for oil and other finite resources.

Some of this has been covered on the site before but maybe they can stand to be updated - any takers?

Not a Solution - Nuclear Power

Sorry, nuke folks. This one shocked me a bit.

http://www.buildup.eu/publications/21162
The contribution of nuclear power to climate protection is relativized when taking into account the declining ore grades: Nuclear power can be referred to as “low-carbon” when the ore grade are high (0,1 bis 2 %). However, ore grades around 0,01 % make the CO2 emissions increase up to 210 g CO2/kWhel. Those emission values are still lower than those of coal or oil (600–1200 g/kWhel), but significantly higher than for wind (2,8–7,4 g/kWhel), hydropower (17–22 g/kWhel) and photovoltaics (19–59 g/kWhel). Moreover it would be costly and slow to use nuclear power as means for reducing green house gas emission; it would take decades, until a net reduction of GHG would have occurred (Pasztor 1991; Findlay 2010). The CO2 avoiding costs of nuclear power are than for any other possible technology except traditional coal fired power plants. Wind power stations and cogeneration of heat and power are 1,5 times more cost-effective in reducing CO2 than nuclear power, energy efficiency measures are 10 times more cost-effective.

The report looked at the state of current uranium mines, ore quality, and needs of reactors put into service today and concluded that most new plants couldn't even be fueled through their entire life with current known uranium reserves, and that the use of more difficult to mine ores results in a net CO2 output HIGHER than natural gas power plants.

Who knew it would be better for the environment to use NG rather than fission? :shock:


Then there are the 'externalities'...
Further problems of nuclear power generation remain unsolved:
- Accident liability is unsolved. Worldwide, nuclear power plants are legally exempt from the liability for catastrophic accidents.
- Health risks from radiation of nuclear power plants cannot be excluded. In Germany, a study conducted by the German Deutschen Kinderkrebsregister (German Paediatric Cancer Registry) proves increased leucemia rates for children in the surroundings of nuclear power plants. (Kaatsch et al. 2007).
- While the Operationable uranium resources will not last longer than this century, the highly radioactive waste has to be stored safely for thousands of years. No storage concept was developed yet for the 245.000 tons of spent fuel elements nuclear power generated already worldwide.
- Nuclear power used for electricity generation is the biggest driver of proliferation of fissile material. Without nuclear power generation, proliferation attempts could be identified undisputedly, because each effort to acquire fissile material would clearly serve military purposes.
- Nuclear power leads to higher electricity prices, because direct and indirect subsidies cover up the enormous costs of nuclear energy. Worldwide no reactor was built, where private investors would have carried the financial risk. If nuclear power in a liberalised market would actually lead to low electricity prices, it should not be a problem to find private investment to build new reactors.
- Nuclear power is a high-risk technology due to the risks connected with it. However, in connection with the need of protecting the climate, this energy form is also called “lowcarbon”.

Note and request: I don't consider this to be a final answer in any way, nor am I in any position to declare anything one way or another. If you have better information and/or a better way to interpret the existing information then PLEASE bring it forward! Thank you !

There are a number of reasons for this, which the industry likes to tout as operational/maintenance improvements. Some of it may actually be due to not really needing the power in the 1970-1980s (built nukes based on future need, takes 10 yrs to finish, since it's a step function, by definition you have 1100 MW excess power when turned on), and now we have reached the point of actually needing/using the power.

<snips>
Thanks Reddy!

We're still working through our 'nuclear fiasco' down here. The South Texas Project has two reactors in place that have been working very well. A few years back the San Antonio municipal power company bought into an NRG Energy/Toshiba plan to install two additional reactors. The project site was prepared for four reactors from the start, water rights already in place, the technology is already licensed/approved, experienced contractors would be brought in, etc. Early on it seemed like a no brainer. Then things started to unravel.

The $5 billion estimate turned into more than $18b, there appeared to be under the table negotiations and active efforts to hide true costs early on. The municipal power company has pulled out and the project will likely be tied to at least two court cases for some time. Tokyo Electric Power pulled their 10% stake after Fukushima.

These events give credence to the contention made over the past five years by opponents of nuclear power that it is a needlessly expensive and risky way to meet future energy needs.. In less than a year, the price of the STP nuclear expansion ballooned from around $5 billion to more than $18 billion. Given this case study of nuclear power’s failure, we must call into question the federal government’s decision to increase federal loan guarantees to support oversized, untenable projects that are already proving too risky for private investors.

Solar has decreased significantly in past few years, I've seen panels approaching $1/W and installed systems around $4-5/W (without incentives). The lack of consistent permitting nationwide has been cited as one reason installation costs are so high. Since solar (and wind) have a capacity factor close to 30%, you get about 1/3 as many kWh as nuke per W installed. Thus, you reach parity around $2-4/W solar. In some parts of the country (CA, HI, AZ, NM, etc.) and in certain remote, costly locations, you are already at or beyond parity.

So here in the west, we don't really need more nukes, but rather more solar installations in CA to handle peak loads, more electric cars in WA to consume the night time excess, and turn off the nuke at night to reduce excess (hmmm, that won't go over very well with the industry).

Andy, that argument is one where it's impossible to disprove any claim because the evidence that would do so is secret, therefore it must be true. The WHO people were granted total access to the area around Chernobyl, and have continued to monitor the people, animals and environment involved plus control groups/areas ever since. If you have proof of any withholding of the data available, you should present it to the people doing the studies, not just make claims about deep, dark conspiracies.

Do you think the Ukraine is colluding with Russia (and Belarus) to minimize the health effects?!?!? The whole reason the Ukrainians asked the international community to come in and do the studies is because they wanted compensation from the Russians, the Russians assumed (correctly) that the Ukrainians would make exorbitant claims for damage and compensation, and the Ukrainians assumed (equally correctly) that the Russians would try and minimize any damage claims. So they eventually agreed to get international help, an independent arbitrator if you will.

I don't see how can you tout the IPCC reports as representing the best consensus science we currently have available on the one hand, despite there being lots of interested parties trying to minimize or criticize them, and at the same time reject the equally international in scope UNSCEAR scientific consensus reports on Chernobyl as being flawed, because there are people/groups who may wish to withhold info. Both are international efforts, with lots of interested parties. Here's the 2008 report on the "Sources and Effects of Ionizing Radiation" [due to Chernobyl]: http://www.unscear.org/docs/reports/2008/11-80076_Report_2008_Annex_D.pdf" onclick="window.open(this.href);return false;

This is incorrect. I did not say that it's "true" - I said that it's 'impossible' to complete proper analysis without complete data. Additionally, we're talking about two different things. I'm somewhat aware that research is being conducted (I've linked some in the Fukushima thread for both Japan and Chernobyl). But I'm also aware that not all info that could be available is, and it's also clear that some info IS being censored for various reasons, including 'national security'.

I spent my professional career in a highly controlled environment and in spite of the nature of the job, I enjoyed full access to info for which I was cleared to see regardless of source. I hit a ginormous information control wall when I retired as I started a business selling long-life synthetic lubricants. I couldn't compare lubricants because it was impossible to get an ingredients list. I also couldn't get access to the performance specifications for the competitor's products - or even the specs generated by the various auto manufacturers the lubes had to be formulated against. The information is tightly controlled, is only available to companies with a 'need to know' and a well-stocked bank account, and is kept away from the advertising industry and the consumer. And that's just engine oil! I hit a similarly-sized info wall when I went back to college to study environmental science - just try to get a report of chemical testing from a US sewage treatment plant...

Yes, researchers around Chernobyl are free to track birds and salamanders and track mutations. They're allowed to compare soil samples to see how soil life is affected as radioactive isotopes decay. But information on the effects on humans is tightly controlled.

Back to this:
Andy, that argument is one where it's impossible to disprove any claim because the evidence that would do so is secret, therefore it must be true.
This is precisely how Monsanto sells Round-Up and GMO seed. They perform closed research and if the results don't look good, they lobby the EPA or FDA or USDA to change the test duration requirement or other parameter so that the lab results from rat tests stop before their livers double in size and thus allow the seed to be sold. It's also why universities are not allowed to purchase seed if they intend to perform lab analysis. "All of our testing is conducted IAW EPA requirements - we comply with all laws." :lol:

edit...
How about fracking fluids in the US? Got any peer-reviewed papers that show that there are harmful interactions between components of frack fluids? There aren't any - and there cannot be any - because the industry won't release the ingredients to researchers. They won't even release full into to physicians that are treating people that have been exposed to the products.
/edit

Believe what you care to - that's up to you. But anyone that thinks wikipedia has all the facts, or that all applicable info is available to public or university researchers is living in dream land.

This is incorrect. I did not say that it's "true" - I said that it's 'impossible' to complete proper analysis without complete data. Additionally, we're talking about two different things. I'm somewhat aware that research is being conducted (I've linked some in the Fukushima thread for both Japan and Chernobyl). But I'm also aware that not all info that could be available is, and it's also clear that some info IS being censored for various reasons, including 'national security'.
Of course data's incomplete, it always is, and that there may be some entities who wish to minimize the severity is easy to believe. That's not the issue, it's whether the missing data would significantly change the results.

I spent my professional career in a highly controlled environment and in spite of the nature of the job, I enjoyed full access to info for which I was cleared to see regardless of source. I hit a ginormous information control wall when I retired as I started a business selling long-life synthetic lubricants. I couldn't compare lubricants because it was impossible to get an ingredients list. I also couldn't get access to the performance specifications for the competitor's products - or even the specs generated by the various auto manufacturers the lubes had to be formulated against. The information is tightly controlled, is only available to companies with a 'need to know' and a well-stocked bank account, and is kept away from the advertising industry and the consumer.

Where have I ever made such a statement, Andy? Here's what I come down to. Let's say that the Chekist in the Kremlin is suppressing data of health effects due to Chernobyl for reasons which seem good to him (and the penalties for opposition to policies of the Russian government tend to be far more sever and often terminal, as we were reminded last Friday), and that his fellow authoritarian dictator and Soviet wannabe in Belarus is doing likewise, so nobody blows the whistle (I could have sworn I saw references to Wikileaks, Manning, Snowden etc, in your post when I skimmed it yesterday, but since they demonstrate how difficult is to is to successfully cover up a major conspiracy that whistleblowers would see exposing as a matter of conscience, perhaps I imagined it. I would have included Ellsberg and others in the list, but again, these are western examples who are unlikely to face summary execution or dying in prison of 'natural causes' at an early age). Edit: Okay, found it back a post or two] Fine. Can you give me any plausible reason why _Ukraine_ would wish to minimize the health effects of Chernobyl?

You get the last word on that, because we've strayed well away from the topic of the thread (not that I'm surprised that happened, as with any controversial subject). I suggest we take further discussion to PM, because I think we've provided enough info from both sides for people to come to their own conclusions about the safety of nukes (not that I expect anyone's opinion to change).

For your first: One cannot judge how the "missing data" would affect the results because they don't have the data. Continuing on, however, I've also provided real-world examples of other areas of the 'human experience' that are being censored or otherwise controlled to protect the profits of multinational corporations, international relations, and national security. In addition, I've given an example of how people with the wherewithal to respond by moving will respond when they know that they're in a dangerous situation and have not a chance at all to either fix the problem or even blow the whistle without being a permanent part of a compost pile.

Nuclear power as we've managed it thus far has a number of serious problems even before it breaks - and as anything else made by imperfect beings it WILL break. Because nuclear power was born from the same highly-controlled national level projects that brought nuclear weapons, and because people and corporations that have enjoyed their status for so long will not easily give it up, it would take a significant revolution in the industry to make it transparent enough.

I'm not saying that there aren't ways to use it, or to improve it, or to evolve it - and ultimately maybe there IS a way to make some type of future-tech reactor part of the solution to our climate problem. But we cannot fix the problems if we refuse to acknowledge that they exist. One might be able to bury themselves deeply enough in peer-reviewed papers so that they forget that the make or break info they need is classified and sitting in a vault somewhere, but it's not a recommended way to evolve.

Coal is a long way from disappearing in China, Andy, nor are nukes.
I didn't say coal was 100% absolutely totally dead, Guy, but it's pretty clearly on its way out. Same for current-tech nukes. It appears that China's economy is starting to turn the corner as well (they're outsourcing some of their production) - when the China bubble pops I expect it'll take much of the old-tech with it.

Fingers crossed.

If there is a “War on Coal”, it’s coming from investors who realize that the era of 19th century energy technology is drawing to a close, and from the Chinese, who realize their system cannot survive continued reliance on poisonous, polluting, water hogging energy.
The numbers tell a grim tale for coal barons.
China’s love affair with coal has come to an abrupt end, with figures released last week showing that consumption fell in 2014 for the first time in 14 years.

A combination of slowing industrial growth and a drive by the government in Beijing finally to take emissions and pollution seriously are the main drivers for the slump in the coal market.

It's the beginning if the end. You may quote me on that. :p :lol:

Future-tech nukes need to "do more with less" water as well...

That it's on the way out in the U.S. I have no doubt, although that way out will still take a few decades to complete. As for China, I think the article's being a bit optimistic. As mentioned in the article, China's economic growth slowed last year, and as I've mentioned they've been replacing old, inefficient coal plants with new, more efficient ones (they've had to import coal for some years to meet demand, and the new plants are trying to reduce the need for that), so a temporary downturn isn't unexpected. And they're certainly getting more pressure from the public re air pollution, so that can help. But AFAIA they haven't altered their long-term building plans yet, and while coal will continue to drop in % terms of their electric energy generation, it's on track to continue to increase as far as absolute numbers go. At the moment they're just increasing generation by everything else too - hydro, wind, solar, nukes, NG, and also starting to push efficiency.

As for water, yes, now that there's a design demand to reduce water use, future nuke plants (and all new thermal power plant designs FTM due to Sec. 316(a) of the Clean Water Act) have included that in their design requirements, generally involving a shift from open (once-through) to closed-cycle cooling, as well as other measures. I saw some numbers somewhere on water use reductions on some design of a new plant, but can't for the life of me remember where. I'll look for it, but won't promise any results. In the meantime, here's a good paper to start:

When we establish the bounds for "acceptable losses" from power generation, is it best to focus only on mortality rates? Or should quality of life or injury be part of the mix?

I commented earlier on my neighbor from Moldova. I found this today:
http://moldovacc.md/chernobyl/foundation.htm
Unfortunately, any mention of the Chernobyl's negative impact on the human health and environment in Moldova had long been tabooed here. Several doctors confessed to us that they had been forced to sign to remain silent about any data or information, they came into possession of, on the Chernobyl's influence on this republic...

The then authorities, seeking in every possible way to leave the Chernobyl consequences unknown to the public, announced officially that Moldova had remained unaffected by the nuclear accident...

Because of this official silence, the Republic of Moldova was not included (unlike Ukraine, Belarus and Russia) into the programs of help rendered by various international agencies and organizations.

The fruits we are harvesting now are particularly bitter. Of more than 3.5 thousand Moldovan citizens who took a direct part in mitigating the Chernobyl nuclear disaster consequences on the site, many people have already passed away, and the majority of those who are still alive have become invalids. In such a small country as Moldova, there are thousands of adults and children suffering hard, often incurable diseases. Leukemia, cancer diseases, malignant tumors take away many hundreds of human lives every year. The number of children is alarmingly growing who have in-born cardiovascular diseases, diseases of muscular and conjunctive tissues, malfunctioning of the nervous and blood-circulation systems and sensorial organs.


The initial report from Ukraine provides convincing evidence in support of earlier reports of a 5-6 fold radiation-related increase in thyroid cancer among those who were young at the time of the accident and includes individual dose estimates on all subjects. The data show a strong, approximately linear dose-response relationship. Other studies in Ukraine include individuals exposed in utero to radioiodines, who may have a raised risk of thyroid neoplasia. The relationships between radiation and autoimmune thyroiditis, follicular adenoma, hyperthyroidism and hypothyroidism have also been assessed. Current efforts utilize national cancer registries for follow-up and various strategies for maintaining contact with these cohorts.

It'll take some time for data from Japan to be gathered and analyzed. Eventually, though, peer-reviewed papers based on the best available information will be published. In the meantime, the future "statistics" are still receiving chronic low-level doses of various substances. Researchers with experience studying effects in the vicinity of Chernobyl are already seeing analogues in Japan. http://www.mynissanleaf.com/viewtopic.php?p=365635#p365635

I agree completely that coal plants should be shut-down. In addition to spreading radioactive material, the carbon, mercury, arsenic, and lead are bioaccumulating right up the food web to humans.

We can do better than this.
