California will produce an extra 4 million tonnes of greenhouse gases if nuclear power plants in the state retire warns the Institute for Energy Research in a recent report.
In June Southern California Edison announced that it would permanently retire units 2 and 3 of the San Onofre Nuclear Plant near San Diego due to high maintenance costs.
“If these nuclear units were replaced by a mix of 71 percent gas-fired generating technology and 29 percent renewable technology, as was added from June 2012 to April 2013 in California, an extra 4 million metric tons of carbon dioxide would be emitted per year, equivalent to 8 percent of California’s 2010 emissions from its electric power sector,” writes IER in a report.
“If gas filled the entire void, the additional carbon dioxide emissions would be about 6 million metric tons, equivalent to the annual emissions from about 1.5 million cars.”
Consumers will also be feeling price pain with an expected rise in natural gas prices, the power substitute that more and more utilities are turning to. The IER warns that nuclear power still costs less than the alternatives.
“Nuclear production costs for existing plants in 2012 averaged 2.4 cents per kilowatt hour, about one-third the cost of a new natural-gas fired plant and about one-fourth the cost of a new onshore wind unit.”
Authors note that nuclear energy makes up 19% of America’s electricity generation. With planned retirements the US will have 99 operating units by the end of next year. A total of 38 units are on a possible retirement list since the cost of renewables and natural gas keeps falling.

Liquid Fluoride Thorium Reactor are the bridge between Nuke and Fusion. Even better, they are designed for 100kw and up. The new modular designs for India, Taiwan, and other countries may bring the cost down from $0.06 KWH to $0.024 KWH.
Ideally, 100+KW modular systems can be located near industry to remove the burden on electrical distribution systems.

San Onofre was not shut due to ‘high maintenance costs’. A problem with new steam generators from Mitsubishi was exaggerated into a shutdown. It’s a complicated and depressing story, but basically a multi-billion dollar machine producing a huge amount of clean energy has been thrown in the garbage.
