Docket No. 50-323-OL Mb h#[W[

Diablo Canyon Units 1 and 2 j e c)

Dear Mr. Stolz:

Evidence concerning environmental qualification of Fan Cooler power cable (Boston cable).was submitted to you in a letter dated November 27, 1978. The environmental qualification claim was based on the results of separate effects testing.

Informal discussions with the Staff have indicated that the separate effects testing may not be acceptable for establishing environmental qualification of these ca.bles. Should the Staff indeed find the testing method unacceptable, we would propose to conduct the sequential testing required to qualify the cable.

Such testing, however, would take considerable time to arrange and complete. The qualification test data already submitted in the November 27 letter certainly supports the safe operation of the Diablo Canyon facility until full qualification can be established. We would consider as reasonable an operating license condition requiring that qualification be established to the satisfaction of the Staff prior to the first refueling outage.

Five copies of this submittal have been sent directly to Mr. Dennis Allison.

Kindly acknowledge receipt of the above material on the en-closed copy of this letter and return it to me in the enclosed addressed enveloce. -
