2.0 Licensee Action on Previous NRC Findings

2.1 (0 pen) Inspector Follow-up Item (50-278/86-10-01): Licensee Not

Performing Type B and C Testing Results Comparison to 0.6 La for

As-found Condition During Non-CILRT Outages.

This item dealt with the method of recording the results for type B

and C leakage tests. The method used by the licensee now masks the

running total for the LLRT criteria. The licensee agrees with the

inspectors' concern, but as of this inspection, has not made any

changes. This item will remain open.

3.0 Local Leak Rate Test Program

3.1 Documents Reviewed

-

ST 30.037 LLRT - RCIC Steam Supply, Revision 5, for penetra-

tion No. N-10, Unit 3

-

ST 30.126 LLRT - Drywell Chilled Water Isolation Valves,

Revision 3, for penetrations N-53 thru N-56, Unit 3

-

ST 30.127 LLRT - RBCW Drywell Isolation Valves, Revision 2,

for penetrations N-23 and N-24, Unit 3

-

LLRT instrumentation calibration records for test box Nos.

1, 2, 3, 4 and 5, standard instruments used to calibrate the

test boxes (rotameters and pressure gages)

3.2 Scope of Review

The inspectors reviewed the above listed documents to determine

compliance with the regulatory requirements of 10 CFR 50, Appendix J,

technical specifications and applicable industry standards. The

inspectors held discussions with the licensee regarding the documen-

tation of test results, the repair and retesting following failed

tests, and the relationship of these items to the "as-found" and

"as-left" conditions of the containment.

3.3 LLRT Procedure Review

The inspectors reviewed specific LLRT procedures being used during

the current outage. These procedures were determined to be techni-

cally accurate and in conformance with the regulatory requirements.

The procedural valve lineups and associated instructions were ade-

quate to allow for the proper venting and draining of test boundaries.

No unacceptable conditions were identified.

3.4 LLRT Instrumentation Calibration Records

The inspectors reviewed the calibration records for the pressure

gages and rotameters in the LLRT test boxes. The calibrations were

current. The standards used also had current calibration and were

traceable to the National Bureau of Standards. No unacceptable *

conditions were identified.

3.5 LLRT Test Box Calibration

The inspectors witnessed the calibration of two local leak rate test

boxes. The test personnel were familiar with the test equipment and

the use of the procedure. The calibration was conducted in accord-

ance with an approved procedure (RT 7.0, Revision 5). The inspectors

verified the documentation of the test result. No unacceptable

conditions were identified.

3.6 LLRT Test Results Evaluation

The inspectors reviewed individual LLRT results and the running

leakage total. The inspectors also discussed analysis of the test

results and the status of repairs and retests with the licensee.

All "as-found" and "as-left" local leak rates are individually item-

ized and incorporated into two running totals, one "as-found" and

one "as-left." This documentation method is being used for CILRT

only. During non-CILRT outages, the licensee uses a different method

of recording LLRT results.. (See paragraph 2.1) No unacceptable

conditions were identified.

.4.0 . Containment Integrated Leak Rate Test (CILRT)

4.1 Documents Reviewed

-

Surveillance Test Procedure ST-12.5-1,. Revision 5, Integrated

Leak Rate Tes' draft version

-

Technical Spe..fications 4.7.A.c, 4.7.A.d

-

4.2 Scope of Review

The inspectors reviewed the above listed documents for technical

adequacy and to determine compliance with requirements of technical

specifications,10 CFR 50, Appendix J, and applicable industry

standards.

4.3 Procedure Review

ILRT Procedure ST-12.5-1, Revision 5, was reviewed in its present

draft stage. The final version is also planned to be reviewed by

the inspectors prior to the upcoming ILRT.

4.4 CILRT Instrumentation

The inspectors reviewed the ISG calculation. It was.found to be

appropriate only for the case where all instrumentation is operable

for the duration of the test. 'It is possible to have one or more

sensors (total pressure, drybulb and dewpoint temperature) fail

during the test. In this case, to meet ISG criteria, the test will

have to be run for a longer duration. The licensee agreed to include

an instrument failure analysis in their calculation. The inspectors

had no further questions at this time.

5.0 QA/QC Involvement in LLRT and CILRT .

LLRT and CILRT activities are monitored by plant QC personnel. QC selects

a sample of LLRT's to be monitored from the outage schedule. These LLRT's

are then reviewed in accordance with a " Detailed Monitoring Checklist"

(DMC) which is' specific to the type of test being performed. The CILRT is

also monitored with a DMC which is specific to the CILRT procedures. The

DMC's were found to be comprehensive and technically useful from a QA/QC

standpoint. QC personnel were knowledgeable of their responsibilities.

No unacceptable ~ conditions were identified.

6.0 Facility Tours

The inspectors made several tours of the facility including the control

room, turbine floor and secondary containment. General housekeeping of

the facility was good. No unacceptable conditions were identified.

7.0 Exit-Meeting

A meeting was held on October 4, 1985, to discuss the scope and findings

of the inspection as described in this report (see Section 1 for

attendees). At no time during the inspection were written inspection

findings provided to the licensee.
