2 Electrical Components and Systems - Work Observation (Unit 1) (51053)

-The inspector selected the following equipment for examination:

Emergency Diesel Generator (EDG) Panel 1-2403-P5-DG3 EDG Panel 1-2403-P5-DG4 125VDC Battery Charger 1-1806-B3-CBA 125VDC Battery Charger 1-1806-83-CBB 4160VAC Medium Voltage Switchgear 1-1804-S3-A03 4160VAC Medium Voltage Switchgear 1-1804-S3-A02 480VAC Load Center 1-1805-S3-BBC 480VAC Motor Control Center 1-1805-S3-BBC 480VAC Load Center 1-1805-SS-BBA 125VDC Power Distribution Panel 1-1806-S3-DCB Conduit IBE311RL117 Conduit 1BE311RL118 Conduit IBE311RL119 The above items were examined to assure that the receiving inspection was completed and documented in the areas of identification, physical condition, certification records and that there was an adequate inspection staf The above items were reviewed using QC records. The in:pector verified that the above equipment is installed in the plant and stored in place pending plant startup. The installation of the equipment exanined was completed and some of the equipment was released for startup testing. The inspector verified that the proper procedures and drawing were used for installation, that the specified materials were used, and that the equipment was properly mounte The equipment was clearly identified and protected from damage during construction activities in the immediate area. The records to verify that EDG "B" panels 1-2403-P5-DG3 and 1-2403-P5-DG-4 had been inspected in accordance with the licensee's procedure No. EG-T-04, Installation of Major Electrical Equipment were not available during this inspectio In a subsequent telephone conversation the licensee indicated that the inspection records had been located and will be available for review during a future NRC inspection. This item is identified as an unresolved item 424/86-14-01, Review the Retrievability of QC Installation Records for Equipment Released for Startup Testin Within the areas inspected, no violations or deviations were identifie . Electrical Components and Systems - Record Review (Unit 1)(51055)

The inspector examined the records for the equipment identified in paragraph 5 abov The areas examined were receiving inspection, identification, specified material, vendor inspections, vendor test reports, and certificates of complianc These records were clear and readily retrievable. The records reflect the reporting of deficiencies on receiving and stored equipmen _ . -. .

The installation records were examined to assure that equipment was installed to the correct drawings and procedures, specified materials were i installed, and the equipment was anchored as required. The inspections were completed and documented except as noted in paragraph 5. The equipment

, installed was adequately separated, independent, and adequate protection was l installed to protect the equipment from construction damage.

t i The licensee is taking action to independently authenticate the qualifi-

cation records for his inspectors. A review of inspector qualifirations is required by the QA program. The review requires verification of education and experienc Within the areas examined, there were no violations or deviations identifie . Licensee Identified Items (Closed) Item 424/CDR 83-48, Westinghouse NLP Printed Circuit Cards (10 CFR 50.55(e)). The final report was submitted on January 6,198 The report has been reviewed and determined to be acceptable. The inspector held discussions with responsible contractor representatives and reviewed supporting documentation to verify that the corrective actions identified in the repoat have been completed. This item involved defective or missing heat sinks on three Westinghouse loop power supply (NLP) printed circuit cards. The cards were installed in ,

Unit 1 balance of plant process cabinet 1604QSPPl. The cards were equipped with a thermal heat sink assembly which was subject to adhesive failure. The three cards found at Vogtle 1 were returned to Westinghouse for modification and documented on deviation report MD5317. The repaired cards have been installed and retested.

I (Closed) Item 424/CDR 83-44 and 425/CDR 83-44, General Electric (GE)

Company SFF-30 Underfrequency Relays Installed in Brown Boveri Electric (BBE) Inc. Switchgear (10 CFR 50.55(e)). The final report was submitted on October 6, 1983. The report has been reviewed and determined to be acceptable. The inspector held discussions with responsible licensee representatives and reviewed supporting documen-tation to verify that the corrective actions identified in the report have been completed. The licensee's vendor BBE identified the potential inability of the SFF-30 relay to pass the Vogtle seismic qualificatio BBE tested a G.E. SFF-30 relay and a BBE device 81 (type FCX103b/1) relay to *he Vogtle seismic profile. The BBE relay was qualified for use at Vogtle. The licensee has decided to use the BBE relay for all underfrequency relays. After evaluation, the licensee has determined that this item is not reportable under >

10 CFR 50.55(e) or Part 21. The inspector concurs with the licensee's evaluatio ]
