PUBLIC SERVICE ELECTRIC AND GAS COMPANY SALEM GENERATING
STATION RESPONSE TO NOTICE OF VIOLATION
The NRC letter dated March 12, 1987 identified
a violation
of Salem Generating
Station CSGS> Technical
Specification
Surveillance
Requirement
4. 6. 1. 1a which is required to ensure primary containment
integrity
is maintained.
During NRC Inspection
50-272/87-03
and 50-311/87-04, the NRC Inspector
reviewed SGS Containment
Integrity
Surveillance
Procedures
CSPC0>4.6.1.1A1-I
and -II> against Unit "as-built" drawings for selected systems penetrating
containment
and identified
five CS> valves which should have been included in the surveillance
but were omitted. These five valves are all located in the piping associated
with the discharge
from various relief valves in the Auxiliary
Building which subsequently
form a common header that penetrates
containment
and discharges
to the Pressurizer
Relief Tank C PRT>. The piping associated
with these valves is only required to have a single check valve inside containment
for isolation.
This single check valve is PR-25, which was itself not included in the SGS Inservice
Testing CIST> Program until a recent program review in July of 1986 Cthe revised IST Program was submitted
to Steven A. Varga, NRC from C.A. McNeill, Jr. on September
24, 1986). During the July 1986 review, the personnel
involved failed to recognize
that the relief valve discharge
lines could have vents associated
with them. This oversight
is attributable
to the normal design of relief valve discharge
lines which are usually solid sections of piping directly piped to a common header or tank. Because the group reviewing
the IST Program failed to recognize
the potential
of vents being installed
on the relief valve discharge
piping, only the common 4 inch header was reviewed for containment
integrity
surveillance
requirements.
1. PSE&G DOES NOT DISPUTE THE VIOLATION.
2. THIS VIOLATION
IS ATTRIBUTABLE
TO A FAILURE BY PSE&G TO ADEQUATELY
REVIEW IST PROGRAM CHANGES AGAINST CONTAINMENT
INTEGRITY
SURVEILLANCE
REQUIREMENTS.
3. IMMEDIATE
CORRECTIVE
ACTIONS: a> Upon no ti fi ca ti on of possible discrepancies, the Shi rt Supervisor
immediately
performed
a detailed review of both Unit *1 and Unit Containment
Integrity
Surveillances.
Because of the known discrepancy
involving
particular
.. : ... *-.... ' -,-. * attention
was paid to relief valve discharge
lines and the Shift Supervisor
identified
4 other vents off relief lines C 2SJ293, 2SJ299, 2CV309 and 2CV365> not included in the containment
integrity
surveillance.
All five of these *valves are identified
in the Notice of Violation.
Additionally, the Shift Supervisor
reviewed Unit tt1 and Unit tt2 containment
surveillances
against each other and found nine <9> other discrepancies.
Certain valves were contained
on the Unit tt1 surveillance
and not on Unit tt2 surveillance, and vice-versa.
After the review or the Containment
Integrity
Surveillances, the Shift Supervisor
had the surveillances
performed
and also had the discrepancies
corrected.
The tagging request inquiry system <TRIS> was updated and the surveillance
lineups were changed to reflect the corrections.
All valves which were noted as discrepancies
on the integrity
lineups were round in their closed positions, as required by their normal surveillance.
After the performance
or the surveillance, all the above noted valves were locked closed. b> In response to the Shift Supervisor's
and NRC Inspector's
findings, the Technical
Department
Procedure
Group completed
a review or the Containment
Integrity
Surveillances
against the SGS Containment
Isolation
System UFSAR Table 6. 2-10. This review verified the Shift Supervisor's
findings and also discovered
ten C10) more discrepancies.
1) Six C6> vent and drain valves associated
with the excess letdown heat exchanger
component
cooling supply line had not been included in the surveillance.
-Two < 2> or these valves C CC180 and CC278> were already locked closed in accordance
with the normal component
cooling water lineup, therefore
they were just added to the integrity
surveillance
lineup -Four <4> of the valves were normally closed in accordance
with the normal component
cooling water lineup, therefore
the normal position or these valves was changed to locked closed. However, three of these valves CCC205, CC110 and CC275> are located in the excess letdown heat exchanger
room Ca locked, high radiation
area inside the bioshield
and essentially
inaccessible>.
Because or the inaccessibility
or these valves, PSE&G will check these valves only on the initial lineup and rely on the fact that they are located in a locked room. The fourth valve CCC274) was added to the containment
integrity
surveillance . .. ., .. -
- -< -... -r-* 2> Four C4> drain valves associated
with the steam generator
blowdown header located inside containment
C11-14GB19)
had not been included in the containment
integrity
surveillance
and therefore
were added to the "inside" containment
surveillance
and their normal position was changed from closed to locked closed. 4. LONG-TERM
CORRECT! VE ACTIONS: PSE&G's long-term
solution for providing
adequate review of design changes and IST Program changes is close coordination
between the System Engineers
and the Technical
Department
Procedures
Group. Due to greater system specific training and design criteria expertise
possessed
by the System Engineers, a better level of review than that which previously
existed is expected.
5. COMPLIANCE
PSE&G is now in full compliance

Specification

Requirement
