Attachment II WASHINGTON PUBLIC POWER SUPPLY SYSTEM NUCLEAR PROJECT NO. 2 DOCKET NO. 50-397 LICENSE NO. CPPR-93 10CFR50.55(e) CONDITION #64 PLANT ELECTRICAL SEPARATION FINAL REPORT Description of Deficiency As a result of a QA program breakdown between GE (Contract 002) and Fischbach Lord (Contract 218), approximately 150 instances involving violations in the application of the WNP-2 Electrical Separation Criteria to safety related cables and panel wiring in the control room were discovered.
Safety Implication The deficiencies found could have resulted, under single failure conditions, in the siaultaneous loss of redundant safety-related equipment with possible subsequent loss of safety function.
The condition was, therefore, concluded to be a reportable deficiency under 10CFR50.55(e).
Cause of the Deficiency QA program breakdown between General Electric and Fischbach/ Lord, due to each thinking the other organization was to implement the QA/QC program requirements necessary to effect PGCC installation.
Corrective Action A 100% inspection of the PGCC was performed by Supply System Test and Startup
-in September 1982. All deficiencies were provided to Burns and Roe. Project Engineering Directive (PED) 218-E-A405 and FDDR-KKl-935 were issued to correct the deficiencies identified by the 100% inspection of the PGCC.
-Action to Prevent Recurrence 7
The Supply System has implemented the following actions to provide corrective action in regard to the QA program breakdown between Contract 002 and Contract 2i. 218.
i us,no EO Corrective Action Request (CAR) 1437 was issued to Contract 218 documenting e
the QA program breakdown. All remedial action has been completed and CAR gg 1437 is closed.
ou 9e Corrective Action Request (CAR) 1439 was issued to Contract 002 documenting o
their QA program breakdown. All remedial action has been completed and CAR
- 8 1439 is closed.
I ogfo Stop Work Order #7 was issued to stop work in the control room until a correc-
- E[ e tive action plan (CAR's 1437 and 1439) could be developed and implemented.
(
Stop Work Order #7 has been lifted.
Reinspections were performed on PGCC routing and cable identification to o
provide cable routing of the PGCC.
PED-218-E-A405 and FDDR-KKl-935 have been issued to correct deficiencies identified during the reinspection.
Attachment II Page 2 cf 4 e Contract 218 is no longer performing installation and inspection activities related to PGCC.
e Contract 002 is no longer directing PGCC installation, but they are still providing engineering direction for the NSSS portion of PGCC.
Burns and Roe is providing engineering direction for the B0P portion of PGCC.
e Supply System Test and Startup is performing all installation and modifica-tion work to the PGCC using 8echtel Power Corporation crafts and procedures.
e The Bechtel procedures used for PGCC installation and modification work incor-porate necessary inspection and installation criteria to ensure proper instal-lation of PGCC.
The Project feels that all remedial corrective action and action to prevent recurrence has been taken. The assignment of Bechtel Power Corporation under the direction of Supply System Startup, for rework / reinspection and future work, will preclude recurrence.
