| |
| "Enforcement discretion was requested [at approximately 1625 CST] and |
| granted [at approximately 1820 CST] by the NRC regarding the [Unit 1] |
| shutdown required by the frozen [recirculation] line. Unit 1 is presently |
| at 23% reactor power. Plans are to raise reactor power to 30% and hold. |
| |
| "Actions underway include [a] 50.59 evaluation of an alternate recirculation |
| path that will restore the operability of one [safety injection] pump. An |
| operability determination is being written to evaluate the operability of |
| the [containment spray pumps] without the recirculation line. These actions |
| are expected to be completed before the expiration of the enforcement |
| discretion at 0140 CST [on 01/06/99]." |
| |
| The licensee plans to notify the NRC resident inspector. The NRC Operations |
| Officer notified the R3DO (Clayton), NRR EO (Hannon), and AEOD IRD |
| (Giitter). |
| |
| * * * UPDATE AT 0152 EST ON 01/06/99 FROM JOHN SELL TAKEN BY STRANSKY * * * |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "The original frozen line has been thawed and is being maintained warm by |
| fluid circulation. An alternate [safety injection] pump recirculation path |
| is currently being utilized, which restores the Unit 1 'B' [safety |
| injection] pump to operable [status]. The use of this path is supported by |
| a 50.59 evaluation and an operability determination. The same operability |
| determination restores both Unit 1 [containment spray pumps] to operable |
| status with minor compensatory measures." |
| |
| "Unit 1 is being returned to 100% reactor power. The unit is in a 72-hour |
| [limiting condition for operation] until the normal [safety injection] |
| recirculation path is restored, which will allow the 'A' [safety injection] |
| pump to be declared operable. This is anticipated later today after |
| restoration procedures are approved and the [safety injection recirculation] |
| line heat tracing is restored." |
| |
| The NRC resident inspector will be informed of this update by the licensee. |
| The NRC operations officer notified the R3DO (Clayton) and NRR EO (Hannon). |

| LOSS OF A 2-µCi AMERICIUM-241 SEALED ANTI-STATIC SOURCE AT MARQUETTE |
| UNIVERSITY IN MILWAUKEE, WISCONSIN |
| |
| At approximately 1300 CST on January 3, 1999, the licensee commenced a |
| search for a missing 2-µCi Americium-241 melted-sealed source (old catalog |
| #AMMQ8485, received during April 1986, internal Marquette identification |
| #RHFAMEAM241AME040586-01). The source was about the size of a hole punch, |
| and it was attached to the goose neck of an anti-static device by a bolt. |
| Both the source and bolt were missing. The licensee stated that the |
| anti-static device was rarely used and that was normally located in the |
| basement of a biology building. The licensee performs quarterly wipe tests |
| and inspections every 6 months. The source was last seen during the |
| performance of one of these surveillances in October or November 1998. The |
| search for the missing source included the applicable room, hallways, and |
| the entrance to the building. The source was officially determined to be |
| lost today (January 6, 1999). |

| UNUSUAL EVENT DUE TO A LOSS OF OFFSITE POWER TO THE EMERGENCY BUSES WHILE IN |
| COLD SHUTDOWN |
| |
| At 1319 CST on 01/06/98, there was a loss of the 138-kV line supplying power |
| to the emergency reserve auxiliary transformer (ERAT) while the reserve |
| auxiliary transformer (RAT) was tagged/switched out of service due to |
| ongoing plant modifications. All three emergency diesel generators |
| automatically started and loaded properly, and they are currently supplying |
| power to the emergency buses. The non-vital buses are being energized via |
| the main power transformer back-feed lineup from the 345-kV source (normal |
| grid). Shutdown cooling is being maintained via the use of reactor water |
| cleanup, and vessel feed is from the control rod drive system. Residual |
| heat removal (RHR) train 'B' was in shutdown cooling prior to this event, |
| and the 'B' RHR pump tripped off when its emergency bus was initially |
| de-energized. The licensee stated that there were no reports of abnormal |
| functions other than the loss of the 138-kV line. |
| |
| A Notification of Unusual Event was declared at 1345 CST due to the loss of |
| the ERAT and RAT (when no sources of offsite power are available). The |
| licensee's procedures do not specifically address credit for having a |
| back-feed capability. The licensee plans to terminate the Unusual Event |
| when either the ERAT or RAT are returned to service and offsite power is |
| restored to safety systems. |
| |
| The cause of the loss of the 138-kV line is being investigated, but it is |
| currently believed to be from insulator damage to the 138-kV line near the |
| town of Clinton, Illinois. |
| |
| The unit has been in an extended shutdown since 09/06/96. |
| |
| The licensee notified the NRC resident inspector, the State of Illinois, and |
| DeWitt County Sheriff. |
| |
| ******************** UPDATE AT 1626 EST ON 01/06/99 FROM DAVID WARD TO |
| TROCINE ******************** |
| |
| The licensee reported that the automatic start of the emergency diesel |
| generators was an engineered safety feature actuation and that the cause of |
| the loss of the 138-kV line had not yet been determined. |
| |
| Shutdown cooling is still being maintained via the use of reactor water |
| cleanup, and vessel feed is from the control rod drive system. The licensee |
| stated that it would take 72 hours for boiling to occur if shutdown cooling |
| was not available. |
| |
| The NRC operations officer notified the R3DO (Clayton), NRR EO (Stolz), and |
| AEOD IRD (Giitter). |
| |
| ******************** UPDATE AT 1717 EST ON 01/06/99 FROM DAVID WARD TO |
| TROCINE ******************** |
| |
| The 'B' RHR pump was restored to service (in shutdown cooling) at 1600 CST. |
| Reactor water cleanup was running prior to the event, and remained in |
| service to provide an alternate means of shutdown cooling. |
| |
| The licensee plans to issue a press release and plans to notify the NRC |
| resident inspector. The NRC operations officer notified the R3DO (Clayton), |
| NRR EO (Zwolinski), and AEOD IRD (Giitter). |
| |
| ******************** UPDATE AT 1814 EST ON 01/06/99 FROM DAVID WARD TO |
| TROCINE ******************** |
| |
| The estimated time for restoration of RAT power is approximately 1800 CST, |
| and the estimated time for exiting the Unusual Event is approximately 2100 |
| CST. |
| |
| The NRC operations officer notified the R3DO (Clayton), NRR EO (Zwolinski), |
| and AEOD IRD (Giitter). |
| |
| ******************** UPDATE AT 1916 EST ON 01/06/99 FROM DAVID WARD TO |
| TROCINE ******************** |
| |
| Offsite power was restored to the RAT at approximately 1750 CST, but it is |
| not yet supplying vital loads. Vital loads are still being supplied via the |
| emergency diesel generators. The estimated time for exiting the Unusual |
| Event is still approximately 2100 CST. Spent fuel pool cooling was |
| maintained throughout this event. |
| |
| The NRC operations officer notified the R3DO (Clayton), NRR EO (Zwolinski), |
| and AEOD IRD (Giitter). |
| |
| ******************** UPDATE AT 2016 EST ON 01/06/99 FROM MAXWELL KIER TO |
| TROCINE ******************** |
| |
| Vital loads are still being supplied via the emergency diesel generators. |
| The licensee currently expects the RAT to supply vital loads at |
| approximately 2100 CST. The estimated time for exiting the Unusual Event is |
| still approximately 2100 CST. |
| |
| The NRC operations officer notified the R3DO (Clayton), NRR EO (Zwolinski), |
| and AEOD IRD (Giitter). |
| |
| ******************** UPDATE AT 2116 EST ON 01/06/99 FROM MAXWELL KIER TO |
| TROCINE ******************** |
| |
| The cause of the loss of the 138-kV line was determined to be a pole over |
| north of Clinton that shorted a couple of phases. Repairs are in progress, |
| and the estimated time of completion is unknown. The estimated time for |
| exiting the Unusual Event is now approximately 2130 CST. |
| |
| The NRC operations officer notified the R3DO (Clayton), NRR EO (Zwolinski), |
| and AEOD IRD (Giitter). |
| |
| ******************** UPDATE AT 2216 EST ON 01/06/99 FROM MAXWELL KIER TO |
| TROCINE ******************** |
| |
| The licensee is currently swapping emergency buses from the emergency diesel |
| generators to the RAT. The licensee is also in the process of restoring the |
| ERAT to service. Repairs to the 138-kV line are complete. The estimated |
| time for exiting the Unusual Event is still approximately 2130 CST. |
| |
| The NRC operations officer notified the R3DO (Clayton), NRR EO (Zwolinski), |
| and AEOD IRD (Giitter). |
| |
| ******************** UPDATE AT 2314 EST ON 01/06/99 FROM MAXWELL KIER TO |
| TROCINE ******************** |
| |
| The root cause of the 138-kV line going down was determined to be down guys |
| on a corner pole where the line taps to Clinton. The guys were possibly |
| severed by a snow plow. This allowed the pole to lean causing the static |
| shield to contact one of the phases. |
| |
| The division 1 and 2 emergency buses are currently being supplied from the |
| RAT, and the licensee is currently placing the division 3 emergency bus on |
| the RAT. The new estimated time for exiting the Unusual Event is |
| approximately 2245 CST. |
| |
| The NRC operations officer notified the R3DO (Clayton), NRR EO (Zwolinski), |
| and AEOD IRD (Giitter). |
| |
| * * * UPDATE 0010 1/7/99 FROM M. KIER TAKEN BY STRANSKY * * * |
| |
| The UE was terminated at 2306 CST on 1/6/99. One offsite power source has |
| been restored to the emergency busses, and the other offsite source is |
| currently being restored. The NRC resident inspector has been informed of |
| the termination. Notified R3DO (Clayton), EO (Zwolinski). |
