COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)
DOCKET NOS. 50-445 AND 50-446 ROCKWELL-TERMINAL BOXES SDAR: CP-86-74 (INTERIM REPORT)
Dear Mr. Johnson:
On October 21, 1986, we verbally notified your Mr. Ian Barnes of a deficiency regarding internal wiring discrepancies and rusty close nipples and fittings in terminal boxes for Unit 2 main steam isolation valves supplied by Rockwell.
Our preliminary evaluation indicates this deficiency potentially effects Units 1 and 2.
This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e). We have submitted an interim report logged TXX-6084, dated November 17, 1986.
Currently, we are reviewing the applicable nonconformance reports and performing a field verification of the affected terminal boxes, conduit fittings and the internal wiring to ascertain the significance of this issue in the event the condition had remained undetected. Our assessment will be determined pending completion of the document review and field verification of affected hardware. These efforts are currently scheduled for completion on March 4, 1987.
We will submit our next report on this issue no later than April 10, 1987.
Very truly yours, L,
