| TWO OF THREE OPERATING REACTOR CONTAINMENT BUILDING (RCB) FANS UNEXPECTEDLY |
| TRIPPED DURING TROUBLESHOOTING OF ENGINEERED SAFEGUARDS ACTUATION SIGNAL |
| (ESAS) RELAYS BY A CONTROL ROOM OPERATOR (CRO). |
| |
| "A CRO was checking the ESAS relays for noise, humming or signs of |
| overheating after the relays had been exercised as a result of de-energizing |
| VBB for 1B Inverter restoration. While trying to identify a humming relay |
| the CRO touched what he thought was the frame of relay 1X1A RCB, but what he |
| touched actuated the relay contacts. This caused AH-E-1B and AH-E-1C to |
| trip. |
| |
| "The crew restarted AH-E-1B and AH-E-1C and followed Alarm response B-1-5 |
| '480V ES Motor Trip.' Electrical prints (209-570 and 209-592) were referred |
| to and showed that the relay is a normally de-energized relay. It sends a |
| signal to the 1S and 1T 480V under voltage circuit, DH-V-4B to open and |
| AH-E-1B/C to trip. The UV relays were verified to have not actuated and |
| they were manually reset as a precautionary measure. DH-V-4B was verified |
| still closed. |
| |
| "It is believed since the CRO only slightly moved the relay and AH-E-1B/C |
| contacts are normally closed when the relay is de-energized and the other |
| three relays are normally open, that the movement was enough to break the |
| closed contacts but not enough to make up the open contacts." |
| |
| The licensee will inform the NRC resident inspector. |
| |
| * * * UPDATE AT 1337 ON 7/20/99 BY SCHORK RECEIVED BY WEAVER * * * |
| |
| The event that occurred on July 18, 1999, was an invalid actuation that only |
| involved the AH-E-1B and AH-E-1C fans that are part of the reactor building |
| ventilation system. Therefore, the requirement for reporting this as an ESF |
| actuation is exempted in accordance with 10CFR50.72(b)(2)(ii)(B)(3)(iii). |
| Thus, GPU Nuclear is withdrawing the 4 hour report |
| |
| A review of the reporting criteria of 10CFR50.73 found that the event is |
| similarly not required to be reported and therefore GPU Nuclear will not be |
| submitting a 30 day licensee event report regarding this issue. |
| |
| Nonetheless, the event has been entered into the GPU Nuclear 10CFR50, |
| Appendix B Corrective Action Program and the cause and corrective action |
| taken in response to this event will be documented in accordance with that |
| program. |
| |
| The retraction of the 4 hour report has been discussed with W. Schmidt, the |
| NRC Senior Resident Inspector. |
| |
| The NRC Operations Officer notified the R1DO Jim Noggle. |

| AGREEMENT STATE REPORT - PERSONNEL OVEREXPOSURE |
| |
| On 07/19/99, the TN Division of Radiological Health (TN DRH) was notified by |
| the Corporate Radiation Safety Officer for GE Inspection Services of an |
| overexposure to an Assistant Radiographer. The overexposure occurred on |
| 07/15/99 and was not reported to the TN DRH within the 24-hour requirement. |
| |
| A radiographer and an assistant were conducting radiography when they noted |
| that the pocket dosimeter was off scale. They ceased operations and sent |
| the dosimeter badges to Landauer for analysis on 07/16/99. According to |
| Landauer, the assistant radiographer received a 17-rem whole body dose. It |
| appears that the operator did not follow proper procedures for use of the |
| device since the source was not returned fully into the camera. TN DRH |
| staff is on site on 07/20/99 conducting an investigation. |
| |
| This is report #TN-99-095. |

| OUTSIDE DESIGN BASES - CONDITION OUTSIDE OF APPENDIX R REQUIREMENTS |
| |
| During an Appendix R baseline project review, a condition has been found |
| that is considered to be outside the Appendix R Safe Shutdown design basis. |
| During a postulated fire on the 26 foot level of the primary auxiliary |
| building, fire related cable damage could lead to spurious opening of a |
| single power operated relief valve (PORV) along with the inability to close |
| its associated block valve. Presently, plant procedures direct operators to |
| isolate air to the containment and vent the instrument air header locally in |
| order to shut the PORV. The local valve operations that are required, |
| however, are in the same area as the postulated fire. Failure to get the |
| PORVs closed in adequate time would place the plant outside of the |
| performance goals of 10CFR50, Appendix R, Paragraph III.L. |
| |
| The licensee notified the NRC resident inspector. |
