Iodine spiking data from commercial PWR operations
It is required, by the Nuclear Regulatory Commission (NRC) to determine the response of a pressurized water reactor (PWR) to a steam generator tube rupture (SGTR) as part of the safety analysis for the plant. The SGTR analysis includes assumptions regarding the presence of fission product iodine in the reactor coolant resulting from iodine spikes. Due to uncertainties in the consequences, the NRC has designated this class of accident as a generic safety issue. The results of a previously completed scoping task were extended, resulting in two data bases on iodine spiking. The first is a compilation of the maximum iodine concentration expected in the reactor coolant system (RCS) during an iodine spike. The second, a subset of the first, is a compilation of the expected iodine release rates (from the fuel into the RCS coolant) during an iodine spike. The results of statistical analyses are presented for these two data bases and conclusions are made regarding guidelines for the analysis of SGTRs with iodine spikes. 19 refs., 10 figs., 8 tabs.
