Subject:
Docket Mos. 50-361 and 50-362 Amendment Application Nos. 184 and 170 RAS /EFAS Channels in Tripped Condition l San Onofre Nuclear Generating Station Units 2 and 3 {
i Enclosure 1 to this letter provides Amendment Application Nos. 184 and 170 to !
Facility Operating Licenses NPF-10 and NPF-15, for the San Onofre Nuclear !
Generating Station (SONGS), Units 2 and 3, respectively. The Amendment Applications consist of Proposed Change Number 501 (PCN-501), which is a request to revise Technical Specification (TS) 3.3.5, "ESFAS-Instrumentation." The proposed changes include restrictions on operation with a channel of the Refueling Water Storage Tank Level-Low input to the Recirculation Actuation Signal (RAS) or the Steam Generator Pressure-Low or Steam Generator Pressure Difference-ligh input to the Emergency Feedwater Actuation Signal (EFAS) in the tripped condition.
This proposed change is the result of an issue identified at another utility, who determined that unacceptable consequences can result from a spurious trip of RAS due to operation with a channel in trip.
The proposed limits on operation with a channel in trip are based in part on Probabilistic Risk Assessment insights. Therefore, the proposed Completion Times are considered to be risk-informed Completion Times.
