| DETERMINATION THAT DUAL INDICATION ON FEEDWATER CONTAINMENT ISOLATION VALVES |
| (WHILE IN THE CLOSED POSITION) MAY RESULT IN THEM BEING DEGRADED |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "While shutting down [the] Unit 2 reactor for a refueling shutdown, leakage |
| past the main feedwater control valves required shutting the feedwater |
| containment isolation (CI) valves to [the] 21 and 22 steam generators (S/G) |
| [in order] to maintain S/G level. With the CI valves in the closed |
| position, the limit switch that provides a white status light on the |
| containment isolation panel indicated the valves to be closed. The other |
| limit [switches] that [provide] a red (open) and green (closed) indication |
| for both valves were both on dual indication. S/G levels were controlled |
| with the CI valves close. The dual indication on the CI valves while in the |
| closed position may result in them being degraded. Containment integrity |
| isolations per operation procedures [were] implemented. Further engineering |
| evaluations and repairs will follow." |
| |
| The licensee stated that a unit cooldown was in progress as part of a |
| refueling outage which began shortly prior to midnight. (Refer to event |
| #36942 for additional information.) |
| |
| The licensee plans to notify the NRC resident inspector. |
| |
| * * * RETRACTED AT 1530 EDT ON 5/17/00 BY ELLISON TO FANGIE JONES * * * |
| |
| "Event Notification #36944 on April 29, 2000 documented a situation during |
| unit cooldown where dual indication (both open and closed positions) on both |
| feedwater containment isolation valves brought into doubt the actual |
| position of the valves and their ability to perform their design bases |
| functions. Further evaluation of the actual positions of the valves, their |
| ability to stop flow, and their design bases functions led to the conclusion |
| that the valves did meet the required functions at the time and were capable |
| of meeting all design bases required functions. Therefore, Event |
| Notification #36944 is being withdrawn." |
| |
| The licensee will notify the NRC Resident Inspector. The Headquarters |
| Operations Officer notified the R3DO (John Madera). |

| THE LICENSEE DECLARED THE DIVISION 3 EMERGENCY DIESEL GENERATOR (EDG) |
| INOPERABLE AND THE PLANT ENTERED AN LCO ACTION STATEMENT. |
| |
| THE DIVISION 3 EDG WAS DECLARED INOPERABLE DUE TO THE SOAK BACK PUMP |
| (SUPPLIES LUBE OIL TO THE DIESEL SO THAT IT IS READY TO START) TRIP FAILURE. |
| THE CAUSE OF THE FAILURE IS A FAULTY RELAY FOR THE PUMP. THEY WILL REPLACE |
| THIS RELAY. THIS EDG SUPPORTS THE HIGH PRESSURE CORE SPRAY (HPCS) SYSTEM |
| FOR SAFETY FUNCTIONS. THE HPCS SYSTEM HAS NOT BEEN DECLARED INOPERABLE AND |
| THE DIVISION 3 EDG IS STILL FUNCTIONAL. THE PLANT HAS 12 HOURS TO BE IN |
| CONDITION 3 AND 36 HOURS TO BE IN CONDITION 4. |
| |
| THE NRC RESIDENT INSPECTOR WAS NOTIFIED. |

| |
| The licensee is retracting this event notification, after further review, it |
| was determined that this event was not reportable as there was a 72 hour |
| delay before action to shut down the plant became necessary. Offsite power |
| was in service and the other EDG was available and in accordance with Tech |
| Specs the licensee had 72 hours to restore the EDG before further action was |
| necessary The Division 2 EDG was returned to service well within the 72 |
| hours. |
| |
| The licensee informed the NRC Resident Inspector. The R4DO (Bill Jones) was |
| notified by the NRC Operations Officer. |

| MANUAL REACTOR TRIP AFTER LOSS OF TWO CONDENSATE PUMPS |
| |
| The licensee was performing preventative maintenance on electrical equipment |
| when an error caused the loss of the '1B' 4160 volt non-vital bus. When the |
| bus deenergized, two condensate pumps were lost resulting in loss of feed to |
| the reactor. The operators manually scrammed the reactor, all rods fully |
| inserted and the plant is stable in Mode 3 with level control from the |
| balance of the condensate and feed system. Pressure control is by RCIC |
| supplemented by SRVs as needed. The plant is continuing to Cold Shutdown |
| and an investigation into the initiating event is pending. |
| |
| A press release is planned by the licensee. The licensee has notified the |
| local and state authorities as well as the NRC Resident Inspector. |
| |
| * * * UPDATE AT 1547 EDT ON 5/17/00 BY VINCE PATTEN TO FANGIE JONES * * * |
| |
| During the plant cooldown received a MSIV closure signal due to low vacuum |
| as a result of breaking vacuum as a result of loss of seal steam to the main |
| turbine. |
| |
| RHR reject to radwaste, 1E12-F049, automatically isolated on a level 3 |
| signal due to momentary reactor vessel level shrink from SRV operations. |
| |
| The licensee is continuing to cooldown the plant. Pressure control is being |
| maintained by RCIC and SRVs. Level control is being maintained with control |
| rod drive (CRD) with level at 29.7 " (about 2 " below normal). |
| |
| The licensee notified the NRC Resident Inspector. The Headquarters |
| Operations Officer notified the R3DO (John Madera). |

| LOST ONE SEED CONTAINING 0.5 MILLICURIE IRIDIUM-192 |
| |
| After applicator removal and the seeds were inventoried, it was determined |
| that one seed out of sixty four seeds was missing. Each of the seeds |
| contained 0.5 mCi of Ir-192. A survey of the patient and room did not find |
| the missing seed. An investigation is ongoing to find the lost seed. It is |
| possible that the right number of seeds were not implanted. The applicator |
| was removed with the seed intact, the seeds are contained in ribbons and the |
| ribbons are retained in the applicator, making it unlikely that the seed |
| would have been lost during the treatment. |
| |
| The patient has been discharged and there is no problem with dose |
| administered with one seed missing at the beginning. Also, there is little |
| safety implications to the public. |
