(Comanche Peak Steam Electric ) (Application for Station, Units 1 and 2) ) Operating Licenses)

-AFFIDAVIT OF ANTONIO VEGA CONCERNING E BOARD QUESTIONS REGARDING QA/QC OVERSIGHT My name is Antonio Vega. My business address is comanche i

Peak Steam Electric Station-("CPSES"), P. O. Box 1002, Glen Rose, Texas 76043. I am the Site QA Manager for - the design, construction and startup testing of CPSES. In that capacity, I am responsible for establishing and directing a Quality Assurance /

Quality Control program on safety-related activities to assure that the plant is safe, reliable and in compliance with regulatory requirements. A statement of my educational and professional qualifications is attached to the affidavit (Attachment A).

-The purpose of this Affidavit is to respond to the Licensing

-Board's request for additional information concerning the status of QA/QC oversight activities on systems that may be called upon to function during fuel loading and precritical testing to protect public health and safety. The Board stated that at least four systems were included in this category, i.e., (1) boron addition and monitoring equipment, (2) reactor monitoring equipment, (3) 9409170438 840913 PDR ADOCK 05000445 g PM

fuel 1 1oading equipment, and (4) reactor. protection systems.

Specifically, the Board requested " evidence concerning the current status of QA/QC oversight of~these systems, including evidence that documentation is adequate to assure that unsatisfactory or non-conforming conditions have been corrected and evidence concerning whether or not there are.' allegations known to the applicants or Staff about the intimidation of QA/QC personnel who l

were working on these systems." -Licensing Board's " Memorandum (RequestEfor Evidence Relevant to Fuel Loading)" (August 24, 1984) at p. 2.

In response to the Board's request, an evaluation of all plant systems was conducted to determine the systems that fell into the category specified by the Board, as.noted>above. Ten

- systems / equipment groupings were identified. These systems are listed in Attachment B. With regard to these systems, a thorough review was conducted to determine if all required inspections had been conducted and verified, as applicable. This review reflected that QC inspections have been performed.and documented on the necessary mechanical, electrical and instrumentation components of i these systems. These inspections include in-process inspections, i

' final. inspections, as-built verification inspections, and Authorized Nuclear. Inspector (ANI) inspections, as applicable.

i Continuing reinspections will be made as appropriate to preserve the integrity of completed inspections.

i 6

In addition, an extensive testing program on these systems has ~ been implemented and will be completed prior to fuel load, including, as applicable, hydrostatic tests on pressure retaining systems, prerequisite testing on components to assure proper component. functional operability, and preoperational testing to assure proper operation as a system. Preoperational testing provides assurance that the systems in question will operate as designed by requiring demonstration testing of the capability of the systems to meet safety-related performance requirements. A summary of the preoperational testing for each of the ten systems in question is set forth in Attachment C.

Conditions found to be unsatisfactory or non-conforming as a result of the**above QA/QC oversight activities have been documented, as appropriate, on Non-conformance Reports, Inspection Reports, Test-Deficiency Reports or in other prescribed manners.

These methods of documentation assure positive control and tracking of such conditions to preclude inadvertent use of defective materials, components or systems. These unsatisfactory or non-conforming items are included in a computerized tracking system which is developed and administered by the TUGCo Startup organization to assure outstanding items are properly prioritized, assigned, and resolved in a timely manner.

The Startup tracking system was reviewed to assess the status of items, identified as unsatisfactory or non-conforming through QA/QC inspections or surveillances of construction and testing

activities, on the ten systems identified in Attachment B. The review reflected that all such outstanding items are scheduled to be completed prior ' to fuel load.

In conclusion, based on the thorough review of QA/QC oversight status described above for the.affected systems, I have  ;

determined that necessary and appropriate QA/QC activities have been conducted and that non-conforming conditions are identified and tracked, as applicable, and are scheduled to be resolved prior to fuel load. Our evaluation reflects that outstanding items will be completed on a schedule to support fuel load and precri'ical Ltesting activities in a -manner which assures the health and safety of the public.

I turn now to the Board's second question regarding the status'of QA/QC oversight (i.e., whether or not there

'are allegations about intimidation of QA/QC personnel who were working on these systems). I have discussed this issue with appropriate personnel in my QC organization, construc- ,

tion and QA/QC for operations. I also have personally reviewed the Quality Assurance Investigation Files, and have had cognizant individuals review allegations made through the QA Hot-line and transmitted to us by the NRC Staff. I also instructed our counsel to review the record compiled on the

A. PROCESS SAMPLING SYSTEM -

This test demonstrated the capability of the Process Sample System to provide liquid and gas samples from designated system sample locations, f including the Reactor Coolant System. The test also demonstrated the  ;

proper operation of the Process Sample System isolation valves, including response ~to engineered safety signals within the required time, i

B., CHEMICAL AND VOLUME CONTROL SYSTEM This testing demonstrated the proper operational capabilities of all of the various portions of the Chemical and Volume Control System, including letdown, charging, and seal water injection to maintain the charging and letdown flows, the seal water injection flow to the Reactor Coolant pumps

- and to provide domineralizer and filter cleaning of letdown water, chemical control, purification, and makeup of the Reactor Coolant System, and boron' P

thermal regeneration for boron concentration control of the Reactor Coolant System. Alternate flow paths for charging and miniflow, response to safety injection signals emergency boration, and redundancy of the boration dilution were also demonstrated. Testing also demonstrated the proper operation of the Boron Dilution Protection Systems to mitigate an inadvertent dilution of the Reactor Coolant System.
