1. Allegation Category: QA/AC 2, Document Control

2. Allegation Number: AQ-33

3. Characterization: It is alleged that (1) inspection reports (irs) of vault documents, design change authorizations (DCAs) and component modification cards (CMCs) were prepared from a computer printout instead of a physical inspection of the plant hardware, as ' required by Brown & Root (B&R) proce-dures; and (2) irs in the vault contained information that did not match the data in the computer. (The computer should have listed the latest revision of the DCA or CMC because this information was used by a quality control document review group to generate inspection reports.)

4. Assessment of Safety Significance: When making the allegation, the alleger provided the NRC Technical Review Team (TRT) with an IR identified as IR DCV-00421. This report contained a notation that record verification was based on a computer tabulation and that the IR was being completed at the direction of the inspector's supervisor. The usual method to account for hardware modifications, based on design change, was to physically compare the hardware to the documentation in the vault. The original IR was dated April 4, 1983. The permanent file copy was marked " Voided" by the origi-nating inspector as of May 20, 1983, with a notation that the report had been superseded by IR DCV-00423. The TRT examined reports IR-DCV-00001 through IR DCV-00423 and determined that only one record verification ef-fort was performed using computer-based data and that all other verifi-cations were done by an assigned qualified inspector and according to ,

applicable procedures. The group supervisor (at the time the allegation l was made) indicated that he had attempted to use the computer tabulation l of design changes to expedite the task of verifying incorporation of changes to' the hardware on a one-time trial basis at the direction of Texas Utilities Electric Company (TUEC) management. Based on the results of the one-time trial, the use of computer tabulations to verify for hard-7 ware modifications was discontinued.

During the time period of the allegation, a special quality control group was in existence to account for hardware modifications to non-ASME seismic

' Category I and nonsafety-related seismic Category II items / hardware. This group has since been discontinued. Procedures governing this group's activi-ties have been deleted from the Brown & Root QA manual, and the account-ability function has been included in the general QC as-built verification program.

5. Conclusion and Staff Positions: The TRT found this allegation to be sub-stantiated in one instance. The deviation from procedure was to try a new method to verify selected types of hardware modifications. When proven unsuccessful, the method was discontinued.

In a telephone interview with the alleger on February 7, 1985, the TRT presented its findings. No new allegations or concerns were identified at that time.
