Technical Specification (TS) 3.3.7.1, Monitoring Instrumentation, requires that
PSEG take
grab samples at least once in every 8-hour period and analyze the sample within the next
4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> when the offgas pretreatment radiation monitoring system is
inoperable. Contrary to the above,
PSEG did not take the required
grab samples when the offgas pretreatment
RMS was
inoperable from July 1 through July 4, 2007. The issue was documented in their corrective action program in notification 20328891. Additionally,
PSEG conducted a root cause analysis to determine the causes of the error.
PSEG determined that the root cause was that radiation protection technicians did not have adequate procedural guidance to perform actions directed in an operations abnormal operating procedure. This finding is of very low safety significance because it did not represent an unmonitored release path and there was not an actual release that exceeded regulatory requirements
