摘要:
针对90O MW压水堆,建立了堆芯稳态热工分析模型.采用COBRA - IⅣ进行堆芯稳态热工水力计算分析.获得堆芯燃料元件温度,堆芯冷却剂流量分配及温度和堆芯各通道偏离泡核沸腾比( DN-BR).结果表明:堆芯冷却剂出口最高温度达338.2℃;堆芯燃料最高温度达1 350 ℃;所有通道燃料包壳外表面温度和燃料芯块的最大值都出现在堆芯中心偏上的位置;堆芯进口附近的偏离泡核沸腾比要远高于堆芯出口附近,且最小DNBR值出现在堆芯中心附近.
Abstract:
The steady-state thermal analysis model of reactor core was established for a 900MW pressurizedwater reactor. The steady - state thermal-hydraulic of reactor core was calculated and analyzed with COBRA-IV. The temperature of fuel element,coolant flow distribution and temperature and the departure from nucleateboiling ratio ( DNBR ) of the reactor core were obtained. The results show that the coolant in the core exits lat-eral flow from the center to the around. The maximum temperature of coolant in the core outlet is up to 338.2℃. The maximum temperature of fuel in the core is up to 1 350 ℃. The maximum temperature of claddingsurface and fuel pellet appears above the center. The DNBR near the inlet is much higher than near the outlet,and the minimum DNBR appears near the center.
