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
雙恆定運行方案是船用
壓水堆核動力裝置的理想運行方案.在這種運行方案下,當裝置穩態功率變化時,冷卻劑平均溫度與蒸
汽壓都保持不變,與通常採用的冷卻劑平均溫度恆定運行方案相比,有效地改善了核動力裝置的總體運行性能,特別是在低負荷運行時,可以提高裝置經濟性、降低主泵運行噪聲、改善二迴路系統的設計、運行和控制條件,這對于提高船用核動力裝置的運行可靠性和安全性具有實際意義
