CONFIRMATORY LETTER NRC BULLETIN 88-08 ENCLOSURE SALEM GENERATING STATION, UNIT NO. 2 DOCKET NO. 50-311 e.
Bulletin 88-08 requested that we review our reactor coolant systems to identify any connected, unisolable piping that could be subjected to temperature distributions due to valve leakage which would result in thermal stresses not evaluated in the design analysis of the piping.
The bulletin agdressed both fatigue cracking induced by thermal cycling and piping distortion caused by thermal stratification.
our' respqnse, dated September 23, 1988, identified three locations in each of the Salem plants where thermal cycling could possibly induce fatigue cracking.
The response also discussed the* possibility of piping distortion of our pressurizer surge lines as described in the bulletin *.
During the fourth refueling outage for Unit No. 2, we performed NDE examination of the three locations in question.
The examinations included 2 11 and 3 11 eves piping, 1.5 11 safety injection piping and the 14" pressurizer surge line.
The NDE results did not identify any recordable indications *.of flaws.
We resolv~d our concern for leakage past the SJ71 valve by removing thi~ valve from Unit No. 2 as part of the BIT tank removal design change modification.
We also conducted a field walkdown of the pressurizer surge line to verify support and HEBA restraint clearances.
This walkdown did not identify any indicative piping deflection.
As described in our September 23, 1988 response to the bulletin, PSE&G will perform the NDE inspections of the suspect locations and verification walkdowns of the pressurizer surge*lines for a minimum of two consecutive outages on each unit to provide continuing assurance of system integrity.
Accordingiy, confirmatory letters will be provided within 30 days of completion of the outages describing the NDE results and all actions taken.
