Inservice Testing (IST) Program - Pumps and Valves (MC 73756)
!
j.
The objectives of this inspection were to evaluate the implementation of (
the South Texas Project Electric Generating Station (STPEGS), Unit 1, IST
program for safety-related pumps and valves, and to assess the adequacy of
[
the testing performed with respect to the licensee commitments and
guidelines of Section XI of the ASME C.de.

a.
IST Program Overview The NRC inspector ascertained from IST program review that the STPEGS, Unit 1. IST program for pumps and valves is subject to the requirements of 10 CFR 50.55a(g); Regulatory Guide 1.26 and the ASME Boiler and Pressure Vessel Code,Section XI, Revision 3; Subsections IWP and IWV, 1983 Edition through Sumter 1983 Addenda.
The STPEGS Final Safety Analysis Report (FSAR), Section 3.9.6, addresses the licensee commitments to ASME Code requirements. These commitments are also referenced in the STPEGS, Unit 1, Technical Specifications Section 4.0.5, dated March 22, 1988.
The licensee's administrative control document, "STPEGS Pump and Valve IST Plan,"
describes the commitments for compliance with the ASME Code and was initially issued on January 23, 1986.
The plan is currently being implemented under Revision 3 dated February 5, 1988.
STPEGS Station Plant Procedures OPGP03-ZE-0004, Revision 6, "Plant Surveillance Program"; OPGP03-ZE-0021, Revision 2. "Inservice Testing Program for Valves"; OPGP03-ZE-0022, Revision 3 "Inservice Testing Program for Pumps"; and OPGP03-ZE-0055, Revision 3, "Plant Surveillance Scheduling," are the four principal administrative procedures that describe the administrative structure and division of responsibilities in implementing the overall IST program.
In addition to the above, the NRC inspector reviewed Supplement 4 of the Safety Evaluation Report (SSER) dated April 7,1987, relative to ASME Code relief requests by the licensee and approvals granted by NRR. The NRC inspector concluded from his review that the IST program appeared to be well structured, complete, and consistent with regulatory and ASME Code requirements.
There were no violations or deviations identified during the above reviews.
b.
Methodology used in Implementing IST Program In assessing the method used by the licensee in controlling the test frequencies, the NRC inspector determined that STPEGS Procedures OPGP03-ZE-0004, Revision 6, "Plant Surveillance Program "
and OPGP03-0055, Revision 3, "Plant Surveillance Scheduling," are the two principal administrative control procedures utilized in implementing the Unit 1 IST test frequencies.
The pump and valve testing is integrated into the plant operations technical specification surveillance requirements and maintained by a surveillance scheduling computer program.
The plant operations manager is responsible for performing and evaluating assigned surveillance procedures and for appointing a divisional surveillance coordinator.
The surveillance coordinator is

responsible for implementing the surveillance scheduling program and
,
specifying the implementation date, frequency, and the administrative window for each surveillance test.
A surveillance-scheduler is responsible for scheduling (specified I
frequencies greater than weekly), pre,m ring, and issuing the surveillance test packages to the operations shift supervisor.
A reactor operations surveillance schedule is developed quarterly, which reflects surveillance tests to be conducted each day, and on each shift during the quarter.
This document is the day-to-day-working schedule utilized by both the operations staff and the surveillance scheduler to assure compliance with the frequency of tests prescribed by technical specifications and ASME Code
requirements.
No violations or deviations were identified.

Review of IST Test Procedures and Test Results
.
,
.
During the inspection, the NRC inspE:: tor made a random selection of i
completed IST operational test procedures in order to verify that
!
'
procedures contained reference values and other pertinent attributes T
prescribed by guidelines of the ASME Code of Section XI.
Articles IWP/IWV-3000.
i
'
,
'
Procedures selected included the following:
'
\\
Test Procedure 1 PSP 03-SI-0007, Revision 2, "Low Head SI
.
~
'
Pump 1A."
Tests Conducted: July 30, August 2, and October 9, 1987.
.
$
Test Procedure 1 PSP 03-RH-0003 Revision 2, and
'
Procedure IPSP03-RH-0006, "RHR Pump 10."
Tests Conducted:
'
'
September 19, 23, and 30; and October 1, 1987.
Test Procedure 1 PSP 03-RM-0001, Revision 3. "Reactor Makeup Water
System-Valve Operational Test." Tests Conducted: May 6 and 17, and August 5, 1987.
i Test Procedure 1 PSP 03-EW-0016, Revision 3, "Essential Cooling
,
Water Valve Checklist." Tests Conducted: August 4,
September 4, and October 3 and 15, 1987.
,
.
No violations or deviations were identified.
d.
Test Witness t
During the period April 4-8, 1988, the NRC inspector accompanied i

Test Procedure 1 PSP 03-CH-0601, Revision 2 "Essential Chilled
Water Pump 11A."
Test Procedure IPSP03-CH-0007 Revision 2, "Esseniial Chilled
r Water System-Valve Operability Test."
(Witness stroke time

tests conducted on eight system valves.)
Test Procedure IPSP03-EW-0002, Revision 4. "Essential Cooling I
'
Water Pump 1A" (including full flow Test-ECW Pump 1A Discharge
,
Check Valve EW0006).
The NRC inspector observed that each test was conducted by an I
operations test coordinator located in the control room and in complete control of each step of the applicable test procedure.
In
addition, the NRC inspector verified that both permanent and
.
temporary installed instruments utilized in the tests were within the
'
,
calibration due dates, calculations required for pertinent data were
>
,
independently verified, acceptance criteria was closely defined, and
~;
independent verifications were conducted whenever procedures dictated, i
>
No violations or deviations were identified.

e.
IST Trending During this inspection, the NRC inspector reviewed the licensee's IST
component trending program status. Although minimum operational data i
has been accumulated for meaningful trending analysis, the licensee t
has established a program wherein each assigned systems engineer is developing trending data on IST components within their assigned systems.
No violations or deviations were identified.

0A Audits
The licensee's QA auditing department incorporated portions of the
'
IST program in a "Test Control" audit conducted during the period July through August 1987.
Since limited IST activities were in progress (pre-operations) at this time, the audit wcs limited to a
!
.
.progrannatic review; however, the licensee's surveillance group has
'
conducted over 79 surveillances during the period January through
.
March 1988, covering such activities as startup, preoperations and
'
test control.
No violations or deviations were identified.
