~Sco e
The inspection consisted of a plant tour and a review of followup actions taken by the licensee and his contractors of electrical workmanship problems related to the installation of the power generation control complex (PGCC).
3.
Plant Tour The inspectors toured various areas of Unit 1 with primary emphasis on the lower relay room, lower spreading room and the control room.
These areas were in various stages of construction.
Electrical/in-strumentation equipment was inspected for obvious defects, construction protection, proper identification and nonconformance control.
House-keeping of all areas was adequate and portable fire protection equip-ment was available.
During the tour, the inspectors discussed gA/gC with the electrical crafts foreman and the area engineer.
No items of noncompliance were identifie.
Status of 50.55 e
Item - Fabrication Dama e to Wirin on Termination Module Connectors for ACR E ui ment The licensee has reported by 50.55(e), defective wiring on the termina-tion module plugs in the PGCC termination cabinets.
Detailed infor-mation is contained in NCR 3231, NCR 3030 and Management Corrective Action Report MCAR-1-29.
It was established that approximately 200 termination modules con-tained damaged wires.
A major cause of the damage was attributed to the manual insertion and extraction of the terminal pins.
Rework of the termination modules is in process at the GE facility.
Subsequent inspection at the site, by the licensee, revealed additional cable/connector problems which have been documented in a supplement to MCAR-1-29.
Rework of the PGCC cable/connectors at the Unit 1 site has not begun.
This work will be accomplished by Bechtel personnel in accordance with GE FDI WJGO, Revision 1, and will entail repair of damaged conductors and/or shortening of cables that are excessive in length.
Corrective actions to preclude recurrence of fabrication inadequacies at the GE facility were defined as:
appropriate training of personnel revisions of fabriaction techniques increased/revised inspection activities assess Unit 2 to assure against similar problems The verification of implementation of the corrective action is the responsibility of Bechtel which will be accomplished by a future audit.
The above items will be reinspected by an NRC inspector during a sub-sequent inspection.
No. items of noncompliance were identified.
