Licensee Action on Previous Inspection Findings (Closed) Unresolved Item (320/76-19-02):
Licensee audit had identi-fied nonconforming conditions in cable and raceway installation.
The inspector examined Audit Report No. GPUSC 76-14 and the Finding
-
Reports which identified the nonconforming conditions as well as the corrective actions recommended and taken.
Inspection procedures had been revised and additional inspection criteria provided; installation requirements had been revised; and, the nonconforming
-
conditions had been corrected or in some cases identified on Deviation Requests (DRs).
(Closed) Noncompliance (320/77-11-01):
Failure to perform required resistance tests between conductors in containment penetrations.
The inspector examined the requirenents for " Inspection Prior to Installation" of General Electric Company (GE) manual GEK-45715
" Electrical Penetrations - Installation Instructions," and B&R Engineering Change Memo (ECM) 3105, Revision 2.
This revision of the ECM was written for clarification of the test requirements and states, in part, "In the case where a single conductor goes through a header hole the only test required is the one between its associated ~
pin and ground...."
The test records showed resistance tests to
-
have been conducted between conductors in the same header hole but resistance from conductor to ground only for a single conductor within a header hole. This item had been identified as a noncom-pliance due to poorly defined requirements of UE&C Procedure ECP-9-2.
This procedure has been revised to clarify the requirerents.
