Abstract
The power output from a nuclear power plant or fossil fuel power plant operating under constant reactor (or furnace) and boiler conditions is varied by increasing the turbine extraction steam during low power demand periods for the purpose of using the steam to heat a low vapor pressure organic material and storing such low vapor pressure organic material under atmospheric pressure at high temperature. During periods of high power demand, the extraction rate from the steam turbine is decreased or even discontinued and the stored hot low vapor pressure organic material is used for boiler feed water preheat and interstage steam reheat.
