| The licensee reported that upon arriving at their work site in Bethesda, MD  |

| early in the morning of 04/22/03 they discovered that their construction     |

| trailer was broken into and a moisture density gauge stolen.  The gauge is a |

| CPN Model # MC1DR, S/N MD00305503 containing 10 millicuries Cs-137 and 50    |

| millicuries Am-241:Be.  The licensee notified the Montgomery County Police   |

| (Case # B03089862).                                                          |

| At 0348 EDT on 4/24/03, the plant experienced an influx of fish on the       |

| intake screens for the circwater and essential service water (ESW) systems.  |

| This resulted in a loss of vacuum to Units 1 and 2 main turbines, which led  |

| operators to manually trip both reactors.  Following the trip, operators     |

| noted that ESW flow to all 4 emergency diesel generators (EDGs) was severely |

| degraded.  This resulted in the licensee declaring all 4 EDG's inoperable.   |

| An alert was declared at 0348 EDT, and the NRC entered Monitoring Mode at    |

| 0506 EDT.                                                                    |

| All EDG's have adequate flow to be used in an emergency, but remain          |

| inoperable.                                                                  |

| The licensee is assessing damage to intake screens and strainers in the ESW  |

| system, and manually backwashing ESW screens.                                |

|                                                                              |

| The licensee made a 4-hour ENS notification under 10 CFR 50.72(b)(2)(iv)(B)  |

| to inform the NRC of the manual reactor trips inserted on Units 1 and 2 at   |

| 0328 and 0329 on 4/24/03 for the reasons listed above.  Post-trip response   |

| of the plant was normal.  Main Steam Isolation Valves were manually closed   |

| on both units due to lowering Reactor Coolant System temperature and         |

| lowering vacuum.  Both units remain in Mode 3.                               |

|                                                                              |

| The licensee made an 8-hour ENS notification under 10 CFR 50.72(b)(3)(iv)(A) |

| to inform the NRC of the Auxiliary Feedwater System (AFW) actuations in      |

| Units 1 and 2 following the reactor trips.  The heat removal path for both   |

| units is via AFW to the steam generator pressure operated relief valves.     |

|                                                                              |

| * * * UPDATE AT 0532 ON 4/25/03 FROM R3 IRC TO E. THOMAS * * *               |

|                                                                              |

| The licensee terminated the Alert at 0521 EDT.  The Alert was terminated     |

| based on having one train of ESW and one EDG declared OPERABLE for each      |

| Unit.  The NRC exited the Monitoring Mode of normal operations at 0532 EDT.  |

| The cause of the actuation was human error when the operator performing a    |

| Reactor Protection System surveillance test mechanically actuated the wrong  |

| relay.  The reactor was in refueling and flooded-up at the time of the core  |

| spray actuation.  There was a minor change in skimmer surge tank level       |

| before Operations personnel were able to manually isolate core spray.        |

| PLANT HAD A SAFETY EQUIPMENT FAILURE                                         |

|                                                                              |

| At 2208 CST, on 4-26-03 the Plant Shift Superintendent (PSS) was notified    |

| that a UF6 Release Detection System smoke detector for the No. 3 Normetex    |

| Pump in C-315 had fired.   Operators responded and found no indications of a |

| UF6 release.   The No. 3 Normetex Pump was in TSR 2.3.1 Mode 4, "Not In Use" |

| at the time the smoke detector alarmed.   Operators then attempted to reset  |

| the smoke detector and a system trouble alarm was received.   The trouble    |

| alarm would not reset and attempts to test fire the smoke detectors for the  |

| Normetex Pumps was unsuccessful.   At the time of this incident, the C-315   |

| No.1 and No. 2 Normetex Pumps were in an operational mode in which the UF6   |

| Release Detection System was required to be operable, TSR 2.3.4.3 Mode 2,    |

| "Withdrawal".   The PSS declared the system inoperable and TSR LCO 2.3.4.3   |

| actions were implemented to establish a smoke watch and place the Normetex   |

| pumps in Mode 3, "Standby".   The failed smoke detector was replaced, post   |

| maintenance testing completed and the system was declared operable at 0053   |

| CST on 4-27-03.                                                              |

|                                                                              |

| The event is reportable as a 24 hour event, as required by 10 CFR            |

| 76.120(c)(2)(l); "An event in which equipment is disabled or fails to        |

| function as designed when the equipment is required by a TSR to prevent      |

| releases, prevent exposures to radiation and radioactive materials exceeding |

| specified limits, mitigate the consequences of an accident, or restore this  |

| facility to a pre-established safe condition after an accident."  The        |

| equipment was required by TSR to be available and operable and no redundant  |

| equipment was available to perform the required safety function.             |

|                                                                              |

| The NRC Resident Inspector has been notified of this event.                  |
