中文拼音 [gāodīyāhuílù]
高低壓迴路
英文
hi-lo-circuit-
Presents the steady - state programming with constant coolant average temperature and constant live steam pressure, an ideal programming for marine nuclear power plant ( npp ), under which, both the coolant average temperature and the live steam pressure of nuclear steam supply system ( nsss ) are constant when the steady state operating condition is varied, and points out that in comparison with the steadysate programming with constant coolant average temperature, the ideal programming can improve the overall operating performance of npp effectively, especially in low - load range, for instance, raise the heat efficiency of npp, decrease the operating noise of main coolant pump, and improve the conditions of design, operation and control of the secondary loop system
