Supplementary information for April 1986 Monthly Report On 3/20/86 at 0957 hours0.0111 days <br />0.266 hours <br />0.00158 weeks <br />3.641385e-4 months <br /> during the performance of ST-25B (MSIV full closure) at 72 percent reactor
- power, Safety Relief Valves (SRVs) B21*RVF051C and *RVF051D were actuated as pressure relief valves to control reactor pressure.
At the time of the initial relief valve actuations described
- above, test observers saw indications that B21*RVF041C opened briefly.
There is no evidence that *RVF041C was actuated as a
pressure relief valve.
Therefore it was determined that a spring actuation in the conservative direction had occurred.
SRV B21*RVF041C will be included in the group of valves scheduled to be tested for set pressure and Icakage.during the next refueling outage.
