Meeting Summary
A meeting was held on April 1, 1986 in King of Prussia, PA., between
representatives of GPU Nuclear and the NRC staff (Attachment 1) to discuss
the status of the current piping reverification program. The activity was
undertaken by GPUN in response to findings identified during the NRC -
Region I inspection for closeout of IEB 79-02 and 79-14 (Report No.
219/85-14) and subsequent meeting in Parsippany with the NRC staff on June
25, 1985.
Further commitments made by GPUN during a meeting with the NRC
staff on November 13, 1985, were contained in inspection report 219/85-37.
In the meetino of April 1, 1986, GpVN presented the revised schedule for
the engineering evaluations and field inspection and modifications asso-
ciated with the reverification program. Details of the above activities
were provided by GPUN during the meeting and are enclosed with this
meeting report (Attachment 2). Other related items and schedular commit-
ments which were discussed during the meeting included:
Completion of the piping and pipe support evaluations is planned
during the 11R outage.
Scoping of piping nozzle loads is intended during the 11R outage.
Operability of safety related piping systems and supports will be
verified before the restart from the 11R outage.
II. IEB 79-02
Verification of anchor bolts (engineering and field) is intended to
be performed during the 11R outage, cycle 11 and 12R outage.
At the startup from 11R outage, supports required for system opera-
bility will meet at least a factor of safety of two (2) for wedge and
shell type anchors.
3.
Conclusion
-1.
GPUN will submit a letter, within three weeks, to document certain
clarifications to its schedular commitments for completion of activ-
ities related to IEB 79-02 and 79-14, and other engineering issues
raised during this meeting.
2.
The licensee will re-evaluate its JC0 to ensure the acceptability of
its restart from the 11R outage with IEB 79-02 and 79-14 incomplete.

3.
GPUN will re-evaluate its plans for the design verification asso-
ciated with IEB 79-14 pending the outcome of field verifications
related to IEB 79-02.
4.
The NRC - Region I staff will follow-up on the following:
-
review of GPUN criteria for inspection and testing related to
-
the disposition cf nozzle loads
-
The status of the licensee's JC0 for 11R restart
-
update NRR-SEP group of results from the piping and pipe support
verification effort
