SUBJECT:

TRIP REPORT - AUDIT OF G & H PIPING CODE On October 8,1985, the Staff and its consultant visited Gibbs & Hill (G&H) Office in New York for auditing the ADLPIPE computer code used by G&H in their piping analysis. This is a follow-up action for our evaluation of allegation AP-26, which questioned validity of code verification and QA maintenance. Audit agenda, summary of findings, and attendance list are attached.

The audit concludes that the alleged computer code was verified and QA maintained in accordance with acceptable procedure. Allegation AP-26 is not substantiated and there is no violation and adverse impact to the Comanche Peak Project. Our evaluation to AP-26 is complete.
