DOCKET N05. 50-445 AND 50-446 SEISMIC DESIGN OF CONDVIT SDAR: CP-86-53-(FINALREPORT) i Gentlemen: j
'i On October 21, 1986, we notified you by our letter, logged TXX-6054, of a l deficiency involving the seismic design of conduit, which we deemed reportable ,
under the provisions of 10CFR50.55(e). Our latest report on this issue was B c TXX-6913, dated November 4,1987.
The additional testing performed to evaluate the ability of the fiber glass l cloth / resin material-to resist torsional moments has been completed. The test results indicate'that the fiberglass cloth / resin material will resist the torsional moments and is an acceptable solution for use outside containment'.
. As an alternative, conduit supports may be substituted as required on a case by case basis for the fiberglass cloth / resin material to resist the torsional moments. ,
Installation of the fiberglass cloth / resin material or optional conduit i supports is currently scheduled for completion by April 20, 1988.
Very truly yours, h,b b W. G. Co nsil 8711170177 871113 5 l PDR ADOCK 05 g:
