Title: Nuclear reactor electric power generator
Inventor: KODAMA TASUKU
IPC: G21D3/12
Filed: 1990-10-01
Abstract: PURPOSE:To enable power change of electric generator without varying the thermal power of a reactor and improve total economy by providing a heat resorvoir to store heat energy generated in the reactor and discharge the heat when necessary. CONSTITUTION:When the heat energy of a reactor is excessive due to an electric power demand decrease, a part of main steam is introduced to a heat resorvoir 18 via a main steam extraction line 19 by opening a valve 21a. The rest of the main steam is exhausted to a high pressure supply water heater 13 via a main steam extraction outlet line 23 to introduce eventurely to a condenser 6. During this process, the temperature of water to supply in the reactor 2 is controlled by controlling the opening of valve 21b. Also, it is controllable by the opening of the valve 21a, if the valve 21c is completely shut during this process. When the power of the generator 5 is increased due to the increase in electric power demand, the valve 21a is fully shut and the valve 21c is opened. Thus, by changing the heat source of the heater 13 from the main steam to the steam extracted from a low pressure turbine 4 and heated by the resorvoir 18, the steam generated in the reactor 2 is efficiently used in a high pressure turbine 3 and the power of the generator 5 is elevated.
