Description

In order to assure steady condensation during safety relief valve (SRV) blowdown, SRV plants are required to limit suppression pool temperature. As a result, BWR plants are required to perform pool temperature transient analyses and to install suppression pool temperature monitoring systems (SPTMS). This paper discusses the factors affecting the SPTMS accuracy and the methods of improving the accuracy. The effect of delayed operator action due to SPTMS uncertainty on the peak pool temperature has been assessed for two types of transient events involving extended SRV blowdown. It was found that SPTMS uncertainty and pool initial temperature did not impact pool temperature as much as depressurization rate. The results of transient analyses also demonstrated the feasibility of raising the technical specification temperature for initiating pool cooling mode to 100 F
