RCS Leak Rate Determination a.
Procedure Review The inspectors reviewed information relating to the determina-tion of Reactor Csolant System (RCS) leakage as described in i
the control room shift log and verified that the procedure used was technically adequate and consistent with regulatory require-ments.
b.
Surveillance Requirements Standard Technical Specifications limit Reactor Coolant System leakage to 10 gpm identified leakage and I gpm unidentified leakage and require that a RCS water inventory balance be per-formed at least once every 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> during steady state opera-tion. The licensee's Technical Specifications contain no specific surveillance requirements on RCS leakage. However, the inspectors noted that the licensee determines RCS leakage daily.
c.
RCS Leak Rate Evaluation A six hour RCS water inventory balance was conducted on September 28, 1981. The inspectors independently monitored and evaluated leak rate data to verify the licensee's calculation of the leak rate.
There was acceptable agreement between the inspectors' and the licensee's leak rate calculations as indicated in the following summary (units are in gpm):

Point Beach Unit 2 RCS Leak Rate Determination a.
Procedure Review The inspectors reviewed information relating to the determina-tion of Reactor Coolant System (RCS) leakage as described in the control room shift log and verified that the procedure used was technically adequate and consistent with regulatory requirements.
b.
Surveillance Requirements Standard Technical Specfications limit Reactor Coolant System leakage to 10 gpm identified leakage and 1 gpm unidentified leakage and require that a RCS water inventory balance be per-formed at least once every 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> during steady state opera-tion. The licensee's Technical Specifications contain no specific surveillance requirements on RCS leakage. However, the inspectors noted that the licensee determines RCS leakage daily.
c.
RCS Leak Rate Evaluation A three hour RCS water inventory balance was conducted on September 28, 1981. The inspectors independently monitored and evaluated leak rate data to verify the licensee's calculation of the leak rate. There was acceptable agreement between the in-spectors' and the licensce's leak rate calculations as indicated in the following summary (units are in gpm):
Measurement Licensee Inspector Computer Manual Gross leak rate 0.142 0.072 0.07 Identified Icak rate 0.000 0.000 0.00 Unidentified leak rate 0.142 0.072 0.07 No items of noncompliance or deviations were identified.

Exit Interview The inspectors met with licensee representatives (denoted in Paragraph 1) on September 29, 1981. The inspectors summarized the purpose, scope, and findings of the inspection.
