SUBJECT:
COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)
DOCKET NOS. 50-445 AND 50-446 ANCHOR BOLTS SUPPLIED BY HILTI SDAR: CP-86-51 (INTERIM REPORT)
Gentlemen:
On July 17, 1986, we verbally notified your Mr. Ian Barnes of a deficiency involving a condition cited at another nuclear facility in which anchor bolts supplied by Hilti do not meet average ultimate tensile loads in certain sizes as published by the supplier. This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e). Our most recent interim report was logged TXX-6093, dated November 14, 1986.
Our evaluation of this issue to date indicates that a comparison of the revised allowable loads with those used for design and the associated safety factors will provide adequate justification for our position that reevaluatien of the existing work and revision to the appropriate technical documents is not required.
We expect to submit our next report by March 20, 1987.
Very truly yours, (Mtd MS W. G. Counsil 58
