.i Duquesne Light-Company.
Dock'et No:
50-412-Beaver Valley Power Station Unit #2 License No: CPRR-105 i
.As a= result of thel inspection conducted on April 6-15 and_May' 7-8,-1987, and in
,i~"
accordance with the NRC Enforcement Policy (10 CFR'2, Appendix C) theLfollowing violation was identifiedi 10 CFR 50, Appendix'B, Criterion III requires that measures shall be establi-
-shed to assure.that design basis for systems and components to which this appendix applies are correctly translated into drawings, procedures and instructions.
.q The Beaver Valley Power cable-specification 2BVS-82B to the Okonite. Company and
.2BVS-309 to the Kerite' Company states in the Insulation Section, paragraph 2, that the cable thermal properties shall be.'such.as to maintain its critical-electrical and physical-qualities during the.40 year plant life expectancy when-the conductor temperature for. normal operation will be 90 C.
This requires measures to be established to prevent the conductor temperature from exceeding l
the 90 C design'11mit.
<j u
Contrary to the above, on April 15, 1987 inspection procedure for prot.ective wrap IP 12.1 dated. March 30, 1987 and installation drawings SECO 1.2.3.4.-A40
'y Rev. 11; A-50 Rev._9, A-52 Rev. 2, did not specify a limit for the maximum e
number of layers of the WT65 siltemp material on extended cable wraps to limit the power. cable conductor temperature to 90 C during normal operating condi-tions. This is supported by the Analysis JO 12241 which indicates that con-tinuously operated loads serviced by number 6 triplex power cables wrapped with more than 2. layers of siltemp tape, can increase the conductor temperature beyond 90 C.
This is a Severity Level IV violation.
