Coal is far cleaner and safer than our current nuclear plants.
All it takes is 1 major nuclear accident to cause thousands of years of contamination.
Using historical electricity production data and mortality and emission factors from the peer-reviewed scientific literature, we found that despite the three major nuclear accidents the world has experienced, nuclear power prevented an average of over 1.8 million net deaths worldwide between 1971-2009 (see Fig. 1). This amounts to at least hundreds and more likely thousands of times more deaths than it caused. An average of 76,000 deaths per year were avoided annually between 2000-2009 (see Fig. 2), with a range of 19,000-300,000 per year.
Likewise, we calculated that nuclear power prevented an average of 64 gigatonnes of CO2-equivalent (GtCO2-eq) net GHG emissions globally between 1971-2009 (see Fig. 3). This is about 15 times more emissions than it caused. It is equivalent to the past 35 years of CO2 emissions from coal burning in the U.S. or 17 years in China (ref. 3) — i.e., historical nuclear energy production has prevented the building of hundreds of large coal-fired power plants.
To compute potential future effects, we started with the projected nuclear energy supply for 2010-2050 from an assessment made by the UN International Atomic Energy Agency that takes into account the effects of the Fukushima accident (ref. 4). We assume that the projected nuclear energy is canceled and replaced entirely by energy from either coal or natural gas. We calculate that this nuclear phaseout scenario leads to an average of 420,000-7 million deaths and 80-240 GtCO2-eq emissions globally (the high-end values reflect the all coal case; see Figs. 1 and 3). This emissions range corresponds to 16-48% of the "allowable" cumulative CO2 emissions between 2012-2050 if the world chooses to aim for a target atmospheric CO2 concentration of 350 ppm by around the end of this century (ref. 5). In other words, projected nuclear power could reduce the CO2 mitigation burden for meeting this target by as much as 16-48%.
We conclude that nuclear energy — despite posing several challenges, as do all energy sources (ref. 7) — needs to be retained and significantly expanded in order to avoid or minimize the devastating impacts of unabated climate change and air pollution caused by fossil fuel burning.

If the oceans die, were not far behind.... not far at all.

Yet nuclear energy is promoted as cleaner and safer than coal...…...
Thermal systems capture the Sun’s heat energy (infra red radiation) in some form of solar collector and use it to mostly to provide hot water or for space heating, but the heat can also used to generate electricity by heating the working fluid in heat engine which in turn drives a generator.

people do realize that a lot of atomic detonations happened on Atolls and shallow pacific islands during the fifties and sixties, right?.....we have had radioactive isotopes circulating in our sea water for a long time.

Well, Cs137 from nuclear tests is still detectable, but not much to worry about.
The Pacific is wide, and deep. A whole hell of a lot of water compared to what's in the tanks at Fukushima. I won't be eating fish from the area, but I'll eat anything I manage to catch here.
Yes, but when they've already found radioactive fish and such on the West Coast.

Fish have been "radioactive" on the west coast since nuclear testing was conducted in the Pacific. I'm not sure what you're talking about.
