IE Bulletin and Circular Followu The licensee's response and corrective actions to concerns identified in the following bulletins and circulars were examined.
The inspector also ensured that appropriate corrective actions determined by the licensee were accurate and complete.
Accordingly, the following bulletin and circulars are considered closed for Unit 2:
IB-79-15 IC-79-19 IC-79-20 Deep Draft Pump Deficiencies.
Loose Locking Devices on Ingersoll-Rand Pump Impellers Failure of GTE Sylvania Relay, Type PM Bulletin 7305, Catalog 5U12-11-AC with a 120V AC Coil IC-79-22 Stroke Times for Power Operated Relief Valves IC-79-23 Motor Starters and Contractors Failed to Operate 3.

U rade (Closed)
- , 'V" ~
Thd*'licensee committed to upgrading the quality and clarity of the SISIP packages, enabling a reviewer to reconstruct the chain of events from the identification of the interaction to final closure of the package.
The licensee developed Appendix K, dated November 30, 1984, to the Systems Interaction Program Manual.
The title of this appendix is, Procedure for Unit 1 File Review and Certification."
The inspector reviewed twenty Unit 1 packages to verify the package quality after the upgrade.
The packages reviewed were:
01-006"001"003 01"020-001-002
.", 03"024"002"001 03-026-013-001 03-037"003-002 06-060-022-002 10-020-002"001 13-010-001-005 13-011-002-001 20-063-003-001 24-007-001-004 25-002"004"001 25-077"001-002 25-119-005-001 28-004-008-001 28-004-017-004 30-001-017-002 30-001-036-001 30-001-091-001 32-001-024-004 The inspector found the packages to be upgraded per the instructions of Appendix K, and that the package contents reflected the requirements of the SISIP manual.
The follow-up item 84-09-01 is thereby closed.
b.
Follow-u Item 84-09-02 Review of Interaction Modifications Acce ted "As-Is" Closed The licensee committed to a review of all interaction modifications accepted
"As-Is" by the SISIP walkdown team during final field verification.
The intent of this review wasto close the loop with engineering, so that engineering documents may accurately reflect t the as-built, or in this case the as-accepted, condition of interaction induced modifications.
Figure K.4.1, of Appendix K to the SISIP Manual, "File Review and Certification Flow Chart,"
instructs the package reviewer to prepare a transmittal to engineering for any modifications accepted
"As-Is".
The inspector reviewed six of the fourteen packages found to have modifications accepted
"As-Is" by the walkdown team.
The packages were:
10-013-003-003 28-006-001-001 24-001-009-001 24-007-006-001 25-181-001-001 30-001"057-001 c ~
Each package was found to have a "Systems Interaction Program Transmittal" to engineering, asking that engineering update their documents to reflect the as-built condition.
In each file there was a.memo=. from engineering responding to the transmittal.
The follow-up jJem 84-09-02 thereby is closed.
Follow-u Item 84-09-03 Com letion of Unit 1 Modifications (Closed)
The licensee committed to completing all SISIP induced modifications prior to issuance of a full power license.
The licensee has supplied documentation to the staff describing completion of the modifications.
The follow-up item 84-09-03 is thereby close d.
Follow-u Item 84-09-04 Continuation of SISIP throu h Plant 0 erations.
Closed i ~i The.licensee'ommitted to incorporate SISIP awareness into their des'ign chan'ge, maintenance, and housekeeping procedures.
The inspector reviewed the following administrative procedures from Volume 1 of the Plant Manual to verify SISIP incorporation into the design change and housekeeping programs:
C-10S1 C-1S5 SISIP Review of Housekeeping SISIP Review of Plant Modifications No special procedure or revision to an existing procedures were require to incorporate SISIP into maintenance activities.
The existing procedure C-40Sl,
"Use of Maintenance Shopwork Follower,"
already meets the intent of maintaining interaction modifications.
Follow-up item 84-09-04 is thereby closed.

Unit 2 Seismicall Induced S stems Interaction Pro ram (SISIP)
Per the request of the Nuclear Reactor Regulation Branch of the staff, the inspector reviewed the Unit 2 SISIP.

b.
The inspector reviewed the following interaction packages:
B15-001-003-001 B15-003-004-001 B16-008-002-002 B17-007-002-001 B18-001"006-001 B18-002-001-003 B20-020-003-001 B20-023-001-002 B20-034-002-001 B22-007-001-003 B23-014-002-001 B24-008-016-001 B28-005-008-001 B30"002-019-001 B32-010-001-001 B01-002-003"003 B01"002-005-002 B01-016-002"001 B03-006-002-003 B03-019"001-001 B03-026-001-002 B03"037-001-003 B06-001-004-002 B06-005-001-019 B06-005-001-027 B09-010-004-001 B09-012-001-001 B09"015-001"002 B10"014-002-001 B13-014-001-001 The; inspector 'found the packages to be complete per the SISIP manual'.
No. deficiencies similar to previous findings for Unit
were apparent.
The inspector reviewed PG&E letter DCL-84-361,
"Systems Interaction Program Status," with the licensee.
As stated in the letter, the Unit 2 program was being implemented in the same manner as the Unit 1 program, but due to lessons learned during the staff inspection of the Unit 1 program, the Unit 2 program has been improved.
This was apparent during the review of the Unit 2 packages and the comparison of them with the Unit 1 package A prequalification effort using Unit 1 program results was utilized to improve; the Unit 2 program.
No written discussion of this effort was-"available at the time of the inspection; however, the licensee stated that this would be documented in the Unit 2 final report.
C.
As stated in the letter, there were three followup items related to comparison of the Unit 1 and Unit 2 programs.
The staff will track this as one open item which will be reviewed for closure when Chapter 9 of SISIP manual has been completed and the post-program reconciliation, of both unit's program results have been performed and documented in a separate report.
The reconciliation report was forecast by the licensee to be complete by June 1985.
(Follow-up Item 85-05-01)
The total number of identified interactions for Unit 1 was 2204.
The total for Unit 2 is 1552.
The difference of 652 interactions will be accounted for by SISIP staff in the reconciliation report.
Initial indication of the lower number for Unit 2 was believed to be due to better walkdown techniques, completion of construction prior to walkdown, and various lessons learned from the Unit 1 effort.
Any items identified by the reconciliation will be addressed.
d.
5.
Unit Before the SISIP for Unit 2 can be determined complete, all modifications required to resolve interactions must be completed.
The licensee stated that all modifications will be performed by January 31, 1985.
Final field verification will normally be completed within two days after a modification has been completed.
(Follow-up Item 85-05-02)
2 Internal Review Pro ram (IRP)
Per the request of the Nuclear Reactor Regulation Branch of the staff, the inspector reviewed the completion status of three IRP modification packages:
2-0034 CCW System - Design Basis for Seismic and Heat Load requirements.
2-1088 Seismic qualification of Unit 2 CCW Heat Exchanger.
2-8010 AEW System - Turbine Bearing Cooling Water and Pump Recirculation System Surges.
The above. packages were audited by the inspector.
No package problems were identified.
The packages, however, are open due to incomplete construction of the associated modifications.
Below is a listing of the IRP packages and their associated open design change packages:
2-0034 2-1088 DC2-EM-12437 DC2-EM-24899 DC2"EM"26320 DC2-SP-24899 DC2-EC"24892 (Open)

Fg
't.'his,,time appdqximately 27 IRP packages are open, consisting of approximately 100'pen DCN's.
Fifty of the 100 open DCN's were for three IRP'ackages relating to raceway supports, rupture restraints, and HVAC duct supports.

Exit A telephone conversation was held January 23, 1985, between the inspector and 1. Horn of PG&E, the SISIP Project Coordinator, to discuss the follow-up items that were a result of the Unit 2 SISIP inspection.
The results of the inspection were also discussed with the Plant Manager and his staff at the conclusion of the inspection on February 1,
1985.
