Effect of low pressurized water reactor containment pressure on peak cladding temperatures
Description
The current regulatory requirement that peak cladding temperatures (PCTs) never exceed 12040C (22000F) at any time during a loss-of-coolant accident (LOCA) is frequently the most limiting factor in setting core peaking factor limits. Of the many plant specific characteristics involved in predicting a fuel rod's thermal response to a LOCA, the containment or back pressure plays a significant role, especially in pressure suppression pressurized water reactor (PWR) containments. The back pressure effect is studied by comparing the predicted PCT histories at back pressure levels of 138, 155, 172, and 207 kN/m2 (20, 22.5, 25.0, and 30 psia). A typical four-loop PWR with 15*15 fuel assemblies is analyzed. 11 refs
