Subject:
Portland General Electric Trojan Nuclear Plant 10CFR21 Report - Docket 50-344 - Report #86-01
Reference:
Peerl ess-Winsmi th Nuclear Grade D.C. Motors Gentlemen:
The following discussion is applicable to subject report:
Background:
Limitorque Corporation nuclear grade D.C. motors are manufactured by Peerless-Winsmith. A lead wire insulation change was made with Limitorque Corporation approval in December '84. This insulation system was utilized on nuclear grade D.C. motors manufactured during the December '84 thru December '85 time period.
This insulation system exhibited a field failure and was reported via subject 10CFR21 Report.
Evaluation:
The failed motor had been electrically tested at both Peerless-Winsmith and Limitorque Corporation prior to release to Portland General Electric / Trojan Plant. Testing confirmed the motor and lead wire to be free of manufacturing defects.
The failure mechanism is not judged to be quality related. The insulation system is physically somewhat stiff and may have been damaged during field installation and set-up.
Recommendation:
To insure that maintenance related activities do not result in a similar event, Limitorque Corporation will develop a " sleeving system" to be applied over the existing lead wire.

'/9 S PDR /
. LANTOROUECORPORATION Shoot No. 2 James Taylor December 19, 1986 Recommendation (Continued)
It is necessary to evaluate the capability of-the sleeved lead wire electrically and environmentally. This will be accomplished by test rather than analysis. Anticipated completion date is 3rd quarter, 1987.
Limitorque Corporation has researched the supply of these motors (customer list attached) and will advise each customer (Attelition:
Purchasing Manager & Q. A. Administrator) via copy of this letter with recommendation to implement the sleeving system upon successful completion of the aforementioned testing.
Further, the motors are identified by the presence of one of the following nameplated serial number data codes:
ZM, NN, PN, QN, RN, SN, TN, UN, VN, WN, XN, YN, or ZN Very truly yours, LIMITORQUE CORPORATION P. McQuillan 1 Quality Assurance Administrator Ic
