Discussion:

During surveillance testing of the Browns Ferry Unit 1/ 2, "D" emergency diesel generator (EDG) on September 16, 2003, a General Electric (GE) type HFA relay in the manual governor control system did not respond properly. Trouble shooting identified that the plastic (Lexan) end of the relay coil had broken and slid down which prevented the relay contacts from closing when the relay was actuated. The licensee's evaluation determined that the failure of the relay would not have affected the EDG automatic start function. The licensee inspected approximately 40 of these relays for the other EDGs and found two similar conditions. The Lexan coil end of an auto start relay for the Unit 1/ 2 "A" EDG was found to be broken, however, it had not interfered with operation of the relay. Also, a relay for the Unit 3 "EA" EDG had two small cracks in the Lexan coil end. This was a spare relay and would not have affected EDG operation. All three of these EDG relays are normally de-energized. The licensee is currently reviewing other applications of GE HFA relays and developing additional actions for their "extent of condition" review. They have identified approximately 1300 -1400 similar relays and are developing visual non-intrusive inspections on a priority basis to begin on September 22.

Regional Action:

The NRC has reviewed the licensee's action to address the three damaged GE HFA relays. Additional licensee actions to address the generic implications of these relay failures are also being reviewed by the NRC.
