- 1. 1.4,

Since the staff considers Item l.;1,to be one of the higher priority items in Generic Letter 83-28, which was issued in July 1983, the description and procedures should be provided prior to initial criticality for Unit 2, and within 90 days for Unit l.
2.
Item 2. 1 requests confirmation that all components whose function is required to trip the reactor are identified as safety-related.
Item
- 2. 1 also requests a
summary report describing the vendor interface program for the reactor trip system components.
The PG&E response of November 7,
- 1983, commits to completing the program by June 1985 for Unit 1
and June 1986 for Unit 2, and it commits to submitting a report detailing the required information by August 1985 for Unit 1 and August 1986 for Unit 2.
The staff considers Item 2. 1 to be one of the higher priority items in Generic Letter 83-28, which was issued in July 1983.
Therefore, PG&E should submit a description of the program and implement it prior to izitial criticality for Unit 2, and within 90 days for Unit l.
3.
Item 2.2. 1 requests a description of the equipment classification program for all safety-related components.

PG&E should submit a description of the program prior to startup from the first refueling outage for Uriit 1 and Unit 2.
4.
For Item 3. 1, PG&E needs to state when the procedures for post-maintenance testing of the reactor trip system components will be reviewed and approved.
According to the PG&E response of November 7, 1983,'a statement confirming implementation of this item will be made by January, 1986.
The staff considers Item 3. 1 to be one of the
. higher priority items in Generic Letter 83-28, which was issued in

PGSE should provide details (what is lubricated, what is inspected, how often, what parameters are trended, with what frequency, etc.) prior to initial criticality for Unit 2, and within 90 days for Unit 1.
6.
For Item 4.5. 1, PGSE needs to state that on-line functional testing of the reactor trip system, including independent testing of the under-voltage and shunt trip f'eatures, is being performed.
.The PGSE response of November 7,
- 1983, commits to submitting a statement by
- July, 1984, regarding completion of this item.
PGSE submitted a
followup response to this item on June 27, 1984.

- features, not the on-line functional testing as indicated in the November 7, 1983, response.
PGSE should submit a statement confirming on-line functional testing for Item 4.5. 1 prior to startup from the first refueling outage for Unit 1 and Unit 2.
