Inspection Summary:
Inspection on January 11-15, 1988 (Inspection Report
No. 50-322/88-01).
Areas Inspected:
Routine unannounced inspection of test witnessing and
administrative control of local leak rate testing and tours of the facility.
Results: One violation was identified.
The inspector noted a procedural
deficiency with the local leak rate test procedure which resulted in overpres-
surizing a test volume.
It is not known if this practice was pervasive and is
viewe'i as a lack of overview of test activities.
This deficiency therefore
constitutes a violation.

2.0 Local Leak Rate Testina (LLRT)
The purpose of this inspection was to ascertain that the LLRT was
conducted in compliance with the requirements and commitments referenced
in the following sections, and that the test results met the acceptance
criteria specified in the station procedures and Appendix J,10 CFR 50.
The procedures were reviewed for their technical adequacy to perform the
intended activities.

2.3 Test Witnessing
.
The inspector witnessed the performance of test activities to verify'
that
approved test procedures were available and in use;
the procedures were adequately detailed to assure satisfactory
performance;
parts and materials were properly identified; and
qualified test equipment and tools were used.
Mass flow-in test of RCIC turbine exhaust isolation valve 1E51*MOV-045
and check valve 1E51*08V-0021 on January 13, 1988 were witnessed.
Also witnessed was the mass flow-in test of RBCCW isolation valve
No. IP42*MOV-047 on January 14, 1988.
These three valves exhibited
'
zero ieakage.
The inspector made the following observation during the LLRT of
1E51*08V-0021: while filling the test volume behind the valve with
water from the condensate transfer system (this check valve is tested
with water by initially filling the test volume and M asuring leakage
by air makeup behind the water slug in the piping), the test person-
nel significantly overpressurized the test volume while "cracking"
open the valve at the condensate transfer tap.
Local indication of
pressure showed a value greater than 100 psig.
The test pressure
called for the volume to be filled and pressurized with water-to
approximately 40 psig, the test pressure is 46 (+2, -0) psig and
accident pressure for the plant is 46 psig. The test personnel then-
>
bled down the volume to the required test pressure and completed the
test.
This is a violation (50-322/88-01-01).
The inspector raised to the licensee the concern that initially over-
'
pressurizing the test volume could help to preseat the valve thereby
influencing the test results.
The licensee then administered a pro-
cedure change to the Type C leak rate test procedure SP 84.654.03,
Rev. 4, cautioning against overpressurizing test volumes utilizing
i
,
water. The caution statement requires the use of a relief valve in

the water supply header set at 40 (+2, -0) psig and suggests the use
of a needle valve to control flow into the test volume. This water
method and caution statement.is applicable for two check valves
each on the RCIC and HPCI pump turbine exhaust lines.
The inspector
reviewed the procedure change notice and found its provisions
acceptable.
2.4 Test Instrumentation
Calibration records for the instruments utilized to conduct the
tests witnessed were reviewed by the inspector. All instruments;
flowmeters, pressure gages, temperature gages were found to be
calibrated within their frequency and were tested by standards
which are traceable to the National Bureau of Standards (NBS).
No unacceptable conditions were identified.
2.5 LLRT Procedure Review and Administrative Control
The inspector reviewed the LLRT procedure to determine its adequacy
of content and adherence to accepted testing methodology. The LLRT
procedure is structured such that every mechanical penetration is
covered by specific valve lineups, piping diagrams, and procedural
steps to conduct the test.
The procedure was found to be technically
correct to perform local leak rate testing utilizing the mass flow-in
method. This method is acceptable per 10 CFR 50, Appendix J and
current industry nractice.
The inspector verified that the LLRT
procedure contained the following pertinent information:
criterion
utilized to determine maximum pathway leakage through a valve / piping
network, test p-ecautions, prerequisites, limitations and actions,
and information and justification concerning valves which are reverse
'
direction tested.
The inspector also reviewed documentation relevant
to the overall administrative control of the local leak rate test
program.
Information which documented the following activity status
was reviewed:
recording of test results, acceptance criterion, sur-
veillance scheduling, and valve maintenance work.
The information
reviewed was well organized and appeared adequate to provide proper
administrative control of the overall LLRT program.
No unacceptable
'
conditions were identified.
3.0 Personnel Training and Qualifications
The qualification and training of selected test personnel were discussed
with a licensee representative.
In addition, the inspector evaluated
the performance of test personnel during test witnessing.
The inspector
determined that the test personnel qualifications met the requirements
specified in ANSI N18.1-1971, "Selection and Training of Nuclear Power
Plant Personnel." They were knowledgeable of their responsibilities and
technical aspects of leak testing.
No unacceptable conditions were
identified.

4.0 Plant Tour
-The inspector made.several tours of the plant facilities including the
reactor. building, turbine building, control room, and plant exterior to
monitor maintenance activities and housekeeping. All areas inspected
were' generally clean and free from debris not affiliated with ongoing
maintenance. No unacceptable conditions were identified.
5.0 QA/QC Involvement
The inspector discussed coverage of local leak. rate testing with represen-
i
tatives from the QA and QC organizations and reviewed selected quality
control serveillance reports on local leak rate test surveillances. QC
'
surveillance reports were comprehensive and findings were well documented.
QA/QC representatives interviewed appeared knowledgeable. of local leak
rate testing and their duties as QA/QC auditors.
6.0 Exit Meeting
)
Licensee management was informed of the purpose and scope _ of the
inspection at the entrance interview.
The findings of the inspection
were periodically discussed and were summarized at the exit meeting on
,
January 15, 1987.
I
Attendees at the exit meeting are listed in Section 1.0 of this report.
At no time during the inspection was written material provided to the
licensee by the inspectors.
The licensee's representatives did not indicate that this inspection
i
involved any proprietary information.
