(Closed) Construction Deficiency Report 84-00-17 Qualification of low voltage power and control type penetration assemblies supolied by Conax Corporation. The reported concern was that Conax Corpo-ration (Conax) during the performance of the Rated Maximum Duration of Rated Short-Circuit Test, had leakage detected at seven feedthroughs at the inboard (primary containment) end, Conax capped the feedthroughs. A subse-quent leakage test verified that the leakage rate was within the acceptance criteria. The leakage rate of the outboard end measured 5.0x10 ' scc /s (He)
which is much less than the acceptance criteria of 10-2 scc /s. Based on the test data and the requirements of Conax test procedure IPS-634 "NMP2 Electrical Penetration-Qualification-Report," this item is considered closed.

(Closed) Construction-Deficiency Report 83-00-16 Failure of Kerite Control Cable to satisfy temperature environmental quali-fication requirements. The 40 mil, 1000 volt fire resistant Kerite control cable is not qualified for use in the the primary containment and portions of the reactor building.
Fifty-one cables have been pulled from the system and are being replaced with fifty-one qualified cables. The inspector verified that the master cable list has been corrected to reflect the replacement cables and that approximately 47 of the 51 cables have been re-installed.
This item is considered closed.
(Closed) Unresolved Item 84-02-03 Identify and provide direction to correct separation, terminal connec-tions, harness supports and other identified concerns within the Power Generation Control Console (PGCC). General Electric (GE) performed a joint engineering / quality control audit on all GE panels.
The nonconformances identified were dispositioned on GE FDDR KG1-1477. Drawing / hardware dis-crepancies have been documented on GE memo RMP 83-1250 dated October 10, 1983 and dispositioned on attached FDDR's. The GE audit and the field quality' control daily inspections provide assurance of correction.
This item is considered closed.
(Closed) Unresolved Item 84-02-04 - Status of class IE electrical /instru-mentation - completed work vs. installed work.
There were differences between the Construction and Quality Control De-partment in reporting the status of completed work. The Construction Department included partially completed installation as 100% complete, while the Quality Control Department included only the completed portions of the installation in their status report.
The licensee has changed their reporting information to reflect the status listed in the Quality Performance Management Program (QPMP) Report No.
