and Structural Integrity Test (SIT) Direc;or R. Worley, Systems Engineer, Plant Engineering Department M. Polishak Lead Engineer, Project Compliance Group S. Phillips. Engineer, Project Compliance Group J. Niess, Systems Engineer, Plant Engineering Department, CILRT Coordinator A. Morrison, Operations, Quality control J. Snyder, Startup Engineer D. Ruthven, Operations Engineer Bechtel C. Sczesny, Quality Control D. Shank, Contractor L. Yourn, SIT Coordinator WJS R. Krause, SIT Consultant NRC J. Tapia, Senior Resident Inspector D. Garrison, Resident Inspector $1T (63050) and CILRT Procedure Review (70307)

The NRC inspector reviewed Procedure No. 2C0195S1013, Revision 03,

"Specification for the Performance of Structural Integrity 'iest on Reactor Containment Building, Units 1 and 2." and Procedure No. 2-RC P-03, Revision 0, "Containment Integrated leak Rate Test (CILRT)."

The NRC inspector reviewed the procedures to verify that the licensee had incorporated the associated regulatory requirements and comitrent The two procedures were also reviewed to check that they both coincided and allowed for the fluid performance of the test. In addition, both proceduros were verified to have the proper approvals a 'icated by appropriate signature The calibration documentation for the test equiptrent (elastic wire strain reter, RTDs, dewpoint hygrometers, voltmeters, and pressure gauges) was

inspected by the NRC inspector. No errors were detected and all l instruments were found to be in calibration for the period encompassing i these tests. The NRC inspector reviewed the certification and training i records of technicians involved in calibrating the test equipment. In  !

addition some randomly selected systems, which were addressed in Procedure l No. 2-RC-P-03, were reviewed against the licensee's Piping and ,

Instrumentation Diagrams (P& ids). This was done to detemine that all .

the appropriate valves in the system were addressed in valvo line up t sheet 9.8.1, and that the valve test positions, listed in the same -

sheet, set their associated systems in correct alignment for the  !

performance of the CILRT. A review was also perfonned by the NRC j inspector to detemine that all appropriate systems were addressed in valve line up sheet 9. !

Finally, both procedures were reviewed by the NRC inspector for technical adequac It was noted that the offic... results for the CILRT will be ,

obtained using the total time metho l For the SIT, the NRC inspector verified that the test equipment inside the [

containment building was installed and that a test station was established i outside the containment building to monitor the test. In addition, the  !

NRC inspector witnessed one of the test station operators perfoming a i channel check on some of the elastic wire strain meters. The NRC l inspector also inspected the designated areas of the containment building f which were mapped to monitor concrete cracks. Finally, during the [

co.tainment building pressurization, the NRC inspector witnessed the test k station operators taking data when the reactor building had reached a f pressure of 10 psig (data taking required by Procedure No. 200195S1013, Step 4.2.4).

l While monitoring the line up process, it was noted that the valve line up f i

for independent verification, it was also noted that the tags that were

being used to identify the valves listed in the procedure were ' CAUTION" i

tags, which also did not have any sign offs for independent verification.

! The NRC inspector addressed this to the licensee. The licensee stated -

recorded separatel> hun che procedure, and filed in a cabinet located behind the Unit 2 control room. The NRC inspector reviewed these files and found them to be adequate. In addition, the NRC inspector witnessed a systems engineer performing one of the independent verifications of the containment building CILRT valve lineup, and also found it to be adequat The licensee assured the NRC inspector that the CILRT procedure would be improved, once the plant goes into operation. This is due to the fact that procedures that become part of plant operations must meet the administrative procedure on independent verification, which contains specific guidelines on how it is perfortred and recorde The NRC inspector reviewed a sample of fifty valves that had been positioned and tagged for this test. No errors or discrepancies were note The NRC inspector accompanied the licensee on the final walkdown of the reactor building on September 23, 1988. This was followed by the closing of the personnel airlock after it was verified that all personnel had been evacuated from the reactor buildin Due to time constraints, the NRC inspector was unable to monitor the corrplete test. The remainder of the test will be monitored by the resident inspector, and the results of that inspection will be addressed in a separate repor No violations or deviations were identified in the review of this program are . Exit Interview An exit interview was held on September 24, 1988. At this exit interview, the NRC inspector sumarized the scope and findings of the inspectio The licensee did not identify as proprietary any of the infonnation provided to, or reviewed by, the NRC inspector.
