Proponents of nuclear power in Utah probably have not noticed an article in the UK Times (July 13, 2009) regarding the problems France is having with its nuclear-power plants, problems that bear on the feasibility of nuclear power in Utah.

France is in the grips of another hot summer, with air temperatures in the 80s. Water temperatures have exceeded the limits under which plants cooled by river water can safely operate.

As a result of the heat, France has had to reduce power generation by one-third and is now importing power from England. Much the same thing happened during the heat wave of 2003.

Reading this, I couldn't help thinking about the nuclear plant proposed for Green River, where summer temperatures are regularly in high 90s. The water temperature of the Green River at Jensen on July 13, 2009, was 23.5 degrees Celsius, almost as high as the maximum allowed for water returned to rivers from France's nuclear plants. During the drought of 1999-2005, Green River water temperatures reached 25.4 degrees.

As the earth warms, high river temperatures will become commonplace. Nuclear plants, especially those dependent on rivers, will become untenable. Utah should avoid this boondoggle now.
