MR Number: 2-99-0010 Summer 1 Date: 04/16/99 Jenkinsville,South Carolina Dockets: 50-395 PWR/W-3-LP Subject: POTENTIAL FUEL ASSEMBLY TOP NOZZLE DEFECT Discussion: On April 13, while removing fuel assemblies from the reactor core, the licensee noted that a fuel assembly, which was withdrawn about eleven feet, was not properly latched. Refueling activities were suspended and personnel not associated with refueling activities exited the reactor building. The partially withdrawn fuel assembly was placed into a vacant core position which would allow for a better visual inspection of the assembly. The licensee had also been unsuccessful in latching the previously discharged fuel assembly which was in the upender in the spent fuel pit. A video camera inspection revealed an approximately one-eighth inch gap between the hold down spring block assembly and the top nozzle. The licensee hypothesizes that with the hold down spring block assembly raised slightly, the fuel handling tool reference and stop pins may be preventing the handling tool from properly latching the fuel assemblies. Also, through video camera inspections, the licensee has identified gaps on other Westinghouse fuel assemblies which were loaded in the same core cycle. The spent fuel pit handling tool was modified to remove the reference and stop pins and the fuel assembly in the upender has been placed in the spent fuel pit. The licensee did not perform the same modification on the fuel handling tool in the reactor building. Since the licensee was successful in removing eleven similar fuel assemblies (loaded in the same core cycle) before the above problems occurred, the licensee believed core offload could resume by utilizing a video camera to verify proper latching. Since the restart of defueling activities at 3:45 a.m. on April 19, the licensee has been successful in latching and moving fuel assemblies. The licensee is considering replacement of the entire top nozzle on those fuel assemblies scheduled to be reloaded that have a gap between the hold down spring block assembly and the top nozzle. A Westinghouse representative is onsite. The reason for the gaps is presently not known. The licensee is evaluating this event for Part 21 reporting applicability. Regional Action: The resident inspectors are following core offload activities. One area that will receive focused attention is the use of the video camera to verify proper latching of the fuel handling tool to the fuel assemblies. Contact: L.

MR Number: 3-99-0028 Braidwood 2 Date: 04/16/99 Braceville,Illinois SRI/RI PC Dockets: 50-457 PWR/W-4-LP Subject: Change in status of Braidwood Unit 2 Discussion: The Unit 2 turbine tripped causing a reactor scram at 4:33 a.m. on April 14. The cause of the turbine trip appeared to be a faulty voltage regulator card. The licensee restarted Unit 2 and went critical at 11:07 p.m. on April 14. However, due to problems with the rod control system the licensee tripped Unit 2 from 12 percent power at 1:01 p.m. on April 15. The start up was observed by the resident inspectors. The resident inspectors responded to the site after the reactor trip and observed the Unit 2 startup on April 14 and subsequent reactor trip on April 15. The licensee repaired the rod control system, restarted Unit 2 and went critical at 5:53 a.m. on April 16. Regional Action: Resident Inspector followup.
