g ST HL AE 1937 Page 1 of 4 South Texas Project Unit 1 Docket Nos. STN 50 498 Response to SQRT Audit Questions SQRT #5 The " Seismic Analysis High Head Safety Injection Pumps" report by Nickerson is not in an auditable form considering the time allowed. An auditable summary of the method of analysis and results (both stresses and deflections) from the analysis is required. This item is confirmatory.
Response
A summary report of the seismic analysis of the STP HHSI pumps is provided in attachment #2.
SQRT #7 The satisfactory completion of the maintenance / surveillance program is to be confirmed and a summary description provided to the NRC.
Response
As mentioned during NPOD's presentation on Maintenance and Surveillance, and as discussed with the audit team members, NPOD is incorporating qualification maintenance requirements into normal maintenance and survoillance programs.
Below are described the three steps of the Qualification Maintenance Program (QMP) which ensure a thorough and consistent integration of the special EQ maintenance requirements into the standard maintenance program.
First, the Preventive Maintenance (PM) forms that are written on qualified equipment are designated as EQ RELATED. This assures adequate engineering review of PM deferrals and revisions that constitute a deviation from vendor recommended maintenance and identifies EQ equipment to craft personnel.
If performance of a corrective maintenance or surveillance procedure will affect the qualification of a component, the action required to reestablish qualification is incorporated into the procedure.
Next, the vendor technical manuals are reviewed and the vendor recommended actions are compared to what is already covered by the maintenance programs.
If deviations from vendor recommended maintenance are noted, the appropriate maintenance procedure is revised, a new procedure in drafted or an Engineering Support Request (ESR) is generated to obtain approval to deviate from the vendor recommendation.
ESRs written against qualified equipment are approved by Engineering.
Finally, the Special EQ Maintenance Book (SEQMB) is reviewed to determine any special qualification maintenance required for each component. These requirements are incorporated into the maintenance programs.

Page 2 of 4 illAP Response to PVORT Audit Questions PVORT #3 In one instance (AF 0091) auxiliary feedwater minimum feedwater recirculation valve, the manufacturer's recommended maintenance had not been included in the plant maintenance program.
Response
Incorporation of vendor recommendation into the maintenance procedures
,has been ongoing. At the time of the audit this particular item had not been addressed. The Yarway vendor manual has now been reviewed and its recommendations incorporated in to the appropriate draft maintenance I
procedures for approval. This process is continuing for all qualified equipment.
PVORT #4 IllAP must confirm by pre op test that performance of the Auxiliary Feedwater Turbine Steam Isolation Valve is adequate for proper turbine operation.
Response
Proper operation will be confirmed by Auxiliary Feedwater System Preoperational Test Procedure, No. 1 AF P 02, which includes as one of its objectives to " verify the AW Isolation and Flow valves response to..."
their initiating signals.
Specifically, for Auxiliary Feedwater Turbine Pump 14 Isolation Valve, 1AF MOV 0019, acceptance criteria includes verification of proper direction of travel, and that it opens in 55 seconds or less against maximum differential pressure. This test is scheduled to be complete 2/28/87.
In one case (Boric Acid Transfer Pump) a piece of equipment was PVORT #5 claimed as being qualified; however, the data provided did not fully support this claim.
Response
See attachment #1 for supplemental inform 2 tion to support the qualification of the boric acid transfer pump.
At the time of the audit, approximately 10 to 15 percent of all PVORT #7 safety related pumps and valves did not have completed qualification. The applicant shall confirm that all safety related pumps and valves are properly qualified and installed prior to fuel load.
In addition, the applicant shall provide written confirmation that the original load values used in tests or analyses to qualify safety related pumps and valves are not exceeded by any new loads. Also, the interface of the as built reconciliation (ABR) program to the EQ Group should be described.

Attrchment 1 s
ST-HL-AE-1937 Page 3 of 4
Response
Confirmation of completed qualification will be transmitted later.
Load verification is accomplished in an ongoing phased process continuing through the ABR program itself. As pump and valves and their piping are installed and enter the preoperational and preservice tests, any implemented configuration or dimensional change from the design upon which original load calculations were based is formally documented and reviewed by the responsible design discipline. When such changes result in load increases beyond established criteria, engineering may issue further design changes to reduce the load or, alternatively, negotiate with the manufacturer for his justification of the increase. The EQ Croup is a direct participant in this review and negotiation.
The ABR program makes a final review of all safety systems to confirm that the configuration and dimensional details are within accepted tolerances.
Any exceptions which would result in a measurable load increase are reported to the responsible design discipline and the process described above is repeated. The ABR program is scheduled to be complete 5/31/87.

Response
The SCEW shoot is being revised. A corrected tag has been installed on the valve and tag numbers on the similar valves in the other trains have been verified as correct.
