For modern fast reactors it really is. Nuclear waste paranoia is one of the main things that holds back feasible cheap green energy in the modern world.
You cannot simply brush aside this issue. Even if we have 100% safe reactors, generating waste that is deadly in a thousand years is simply not a good idea, no paranoia involved.
Besides: nuclear had its chance - they blew it because of greed and sloppiness, the usual thing that happens when large organizations deal with complex issues. I am 100% sure that even with novel reactor designs the same "human factor" would generate accidents like we have seen with the old designs.
Greed and sloppiness? Everyone will grant you that in the case of the Soviet nuclear energy program and the result with Chernobyl, but beyond that, there's nothing to support your argument. If anything, the fact that the only significant accident was the result of human error magnified by institutional decision-making is a remarkably positive argument. Modern reactor designs and procedures are radically different than they were back in the 60s. Ignoring the progress of technology and the safety benefits that it results in is an incredibly narrow-minded position. We learn from history in every other field; what supports your conclusion that nuclear power is somehow different?
There's a huge difference between any nuclear power plant and the Hanford Site, which was setup as a wartime production facility. The majority of the river contamination took place in the early years, from 1945 to 1951 when knowledge, technology, and experience was extremely limited at the time compared to today. At the time, they sacrificed environmental concerns for expediency because they had a war to win. Even if they knew exactly what would happen in the years and decades afterwards, I'm fairly certain that the same decision would be made. We're stuck with the cleanup, but there's nothing about the situation that would suggest the possibility of a repeat.
http://en.wikipedia.org/wiki/Fukushima_Daiichi_Nuclear_Power...:
"In 1990, the U.S. Nuclear Regulatory Commission (NRC) ranked the failure of the emergency electricity generators and subsequent failure of the cooling systems of plants in seismically very active regions one of the most likely risks. The Japanese Nuclear and Industrial Safety Agency (NISA) cited this report in 2004. According to Jun Tateno, a former NISA scientist, TEPCO did not react to these warnings and did not respond with any measures.[35]
Filmmaker Adam Curtis mentioned the risks of the type of boiling water reactors cooling systems such as those in Fukushima I,[36] and claimed the risks were known since 1971[37] in a series of documentaries in the BBC in 1992 and advised that PWR type reactors should have been used.
Fukushima had been warned their seawall was insufficient to withstand a powerful tsunami, but the seawall height was not raised in response"
Still no indication of greed, sloppiness, cut-corner mentality and general incompetence?
It's not paranoia. There are legitimate concerns about storing nuclear waste. It's not perfect and it is expensive. Wouldn't it be better to be able to skip past these problems onto something without those drawbacks?
Very substantial amounts of nuclear waste already exist.
Stopping making more doesn't make the problem go away (...at least for many thousand years). I'm more optimistic that current waste will be reprocessed or stored safely if nuclear power generation continues than if it all gets quietly forgotten.
A modest proposal would be to slowly depopulate Micronesia and store all our radioactive waste there (we already tested nukes there once anyway). It's either that or let the ocean reclaim the islands over the next 100 years. So we might as well get some cheap energy out of the deal.
You are getting downvoted without explanation here. It's a reasonable thought except for a few things. First of which is our space launch and delivery systems aren't 100% reliable. Even one failure means nuclear debris spread over a wide distance - something that would be very difficult to recover from.
I couldn't find a good document from a quick googling, but this was high on the list: http://www.spacelaunchreport.com/log2013.html 81 launches and 3 failures. I don't particularly like those odds.
Aside from safety, there's another insurmountable obstacle to space disposal: cost. You may not appreciate just how much spent fuel there is. I did the math once. Launch cost per pound, times number of pounds of waste, came out to over $1 trillion. Orders of magnitude away from feasibility, even with advancements in launch technology.
Compared to a golden age of climate change? In the US, political fear-mongering under Carter killed fuel re-processing; even though it's currently less economical, the ability to lower high-level waste to 1/5th current levels is the sort of thing that can shift the analysis compared to long-term storage. Beyond that, Gen-IV reactor designs can be used to close the nuclear fuel cycle while a number of them can also be used to recycle current waste.
In any case, I'm not sure people realize just how little waste has been produced by volume. Even with the once-through fuel cycle, it's a manageable issue. The biggest problem remains NIMBYism and posturing. It might not be a silver bullet, but it's the damn closest to it.
We're already in a golden age of nuclear waste. Due to the same irrational fear and NIMBY attitudes that has held back modern nuclear power we don't have a good way of dealing with our current waste. It's piling up all over the place.
