'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

TXX-6913, dated November 4,1987.

c 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.
