| UNIT 1 TRAIN 'B' ESSENTIAL SERVICE WATER PUMP STARTED AUTOMATICALLY          |
|                                                                              |
| While setting up for testing the Solid State Protection System (SSPS) on     |
| Unit 2, the clearance permit did not anticipate the start of the Unit 1      |
| train 'B' Essential Service Water (ESW) Pump.                                |
|                                                                              |
| "To perform maintenance on the SSPS, a clearance to deenergize the SSPS      |
| cabinets in Unit 2 was written.  The Unit 2 SSPS was in inhibit at this      |
| time.  During the deenergization per this clearance, an automatic start of   |
| the Unit 1 East ESW Pump occurred.  The ESW Pump autostart was not           |
| anticipated or described in the clearance.                                   |
|                                                                              |
| "A Safety Injection (SI) signal through SSPS in either Unit 1 or Unit 2 will |
| cause the ESW Pumps in both units to autostart for the train effected.       |
| Similarly, the removal of power from the control room instrumentation        |
| distribution circuit, which is what occurred here, will cause the autostart  |
| of the ESW pumps.                                                            |
|                                                                              |
| "There were no adverse consequences as a result of the auto pump start and   |
| the actuation was per the system design.  No SI signal was generated."       |
|                                                                              |
| The licensee notified the NRC Resident Inspector.                            |
|                                                                              |
| * * * UPDATE AT 1822 ON 5/10/00 BY WOODS RECEIVED BY WEAVER * * *            |
|                                                                              |
| "The original report was made regarding an automatic start of the Unit 1     |
| East Essential Service Water (ESW) Pump during maintenance, and was          |
| conservatively reported as an automatic actuation of an Engineered Safety    |
| Feature (ESF).  Subsequent reviews of the pump start event and the           |
| reportability requirements of 10 CFR 50.72 and 50.73 have confirmed that     |
| this event is not reportable.                                                |
|                                                                              |
| "In the case of the start of the 1 E ESW Pump, the ESF actuation slave relay |
| never was actuated, but was deenergized and would not have actuated.  No     |
| other portion of the associated ESF actuation circuitry was completed.       |
| Additionally, the ESW pump was not manually started in an emergency response |
| to plant conditions that would have required the pump to be operating.       |
|                                                                              |
| "NUREG-1022, Revision 1,  Event Reporting Guidelines: 10CFR50.72 and 50.73,  |
| Part 3.3.2,  Actuation Of An Engineered Safety Feature Or The RPS,  provides |
| guidance for the reporting requirements of an ESF actuation event as listed  |
| in 10 CFR 50.72 and 50.73.  The NUREG states that actuation of certain       |
| single ESF components of complex systems need not be reported.  Single       |
| components of complex systems, by themselves, usually do not mitigate the    |
| consequences of significant events.                                          |
|                                                                              |
| "Based on the facts that this event was an inadvertent start of a single     |
| component that would not mitigate the consequences of a significant event,   |
| and that the minimum amount of ESF actuation logic, i.e., the slave relay,   |
| did not actuate, the event is not reportable under 10 CFR 50.72 or 50.73.    |
| Therefore, the 4 hour non-emergency report, event number 36921, is being     |
| retracted."                                                                  |
|                                                                              |
| The licensee informed the NRC resident inspector of this report.  The        |
| Operations Center notified the R3DO (CLAYTON).                               |

| During final walkthrough for renovation of the Waring Chemistry Building,    |
| one tritiated exit sign appears to be missing.  Eleven signs were collected, |
| but there appeared to be a "spot" on the wall at one exit where it appears a |
| sign had hung.  A search was conducted of the building without finding any   |
| indication of the sign.  There is no inventory of the signs so there is no   |
| positive way of determining that a sign is actually missing.  The sign would |
| by a model 101 by Shield Source Incorporated if it matches the rest of the   |
| signs.  The sign contained 7 curies of tritium on 1/93 and would contain     |
| about 5 curies now.  The university plans to send out a flyer looking for    |
| the sign and provide warning of the hazards involved.                        |
