RE: What France plans to do with its nuclear waste
194 degrees Fahrenheit is extremely low temperature for generating power. The resultant energy would be less valuable than the cost of security for a facility. Conventional steam power plants discharge heated water not that much cooler. The problem of a central storage facility usually lies in the transportation issue and as the radioactive materials lose temperature they become less of any form of thermal asset in generating power. In general there is no economic benefit once valuable radionuclides are removed.
