It was determined that although the document contained | | some low level safeguards information, the document could not have | | significantly aided an adversary in defeating a security barrier or in | | carrying out an act of radiological sabotage as the key piece of safeguards | | information, an encryption table, was not filled out. Based on that | | determination JAF is withdrawing the one-hour telephone notification | | (EN-39777). The event remains a loggable event per 10 CFR 95.57(b). It was | | entered into the Security Log at the time of notification. The event has | | also been entered into the licensee's corrective action program for apparent | | cause determination. | | | | The NRC Resident inspector was notified and the state will be notified. | | | | Notified the Reg 1 RDO(Gray) | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |General Information or Other |Event Number: 39780 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: MARYLAND DEPT OF THE ENVIRONMENT |NOTIFICATION DATE: 04/22/2003| |LICENSEE: ENGINEERING CONSULTANT SERVICES |NOTIFICATION TIME: 11:05[EDT]| | CITY: FREDERICK REGION: 1 |EVENT DATE: 04/22/2003| | COUNTY: FREDERICK STATE: MD |EVENT TIME: [EDT]| |LICENSE#: MD2103701 AGREEMENT: Y |LAST UPDATE DATE: 04/22/2003| | DOCKET: |+----------------------------+ | |PERSON ORGANIZATION | | |HAROLD GRAY R1 | | |TOM ESSIG NMSS | +------------------------------------------------+MATT HAHN IAT | | NRC NOTIFIED BY: ALAN JACOBSON | | | HQ OPS OFFICER: MIKE RIPLEY | | +------------------------------------------------+ | |EMERGENCY CLASS: NON EMERGENCY | | |10 CFR SECTION: | | |NAGR AGREEMENT STATE | | | | | | | | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | STOLEN MOISTURE DENSITY GAUGE | | | | 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.

On 04/23/03, at 18:15 CDST, the | | 1A Diesel Generator was made inoperable for a scheduled surveillance. | | Concurrent with this inoperability, the 0 Diesel Generator received a | | spurious CO2 actuation signal. This spurious CO2 partial logic actuation did | | not result in an actual CO2 injection into the 0 Diesel Generator Room. The | | CO2 system partial actuation however resulted in several ventilation dampers | | failing closed as designed. With these dampers closed, the ventilation | | support system for the 0 Diesel Generator became inoperable, the 0 Diesel | | Generator was declared inoperable at 1923 hours 04/23/03. This condition | | resulted in both the 1A and 0 Diesel Generators concurrently being | | inoperable. Actions were taken to terminate the 1A Diesel surveillance and | | restore the 1A Diesel Generator to an operable status. This was accomplished | | at 1952 hours 04/23/03. The 1A and 0 Diesel Generators were simultaneously | | inoperable for 29 minutes. Due to the concurrent Diesel Generator | | inoperabilities which affect redundant trains required to mitigate the | | consequences of an accident, it has been determined that this event is | | reportable as an 8 hour ENS notification. | | | | "Corrective actions have been initiated to address the 0 Diesel Generator | | CO2 system and restore the ventilation dampers to an operable status. The | | spurious actuation of the 0 Diesel Generator CO2 system was determined to be | | due to a Non-Licensed Operator opening the fire detection panel for | | inspection." | | | | The licensee notified the NRC Resident Inspector. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 39790 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: COOK REGION: 3 |NOTIFICATION DATE: 04/24/2003| | UNIT: [1] [2] [] STATE: MI |NOTIFICATION TIME: 04:40[EDT]| | RXTYPE: [1] W-4-LP,[2] W-4-LP |EVENT DATE: 04/24/2003| +------------------------------------------------+EVENT TIME: 03:48[EDT]| | NRC NOTIFIED BY: STUART SCHUETTPELZ |LAST UPDATE DATE: 04/24/2003| | HQ OPS OFFICER: ERIC THOMAS +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: ALERT |MONTE PHILLIPS R3 | |10 CFR SECTION: |JAMES LYONS NRR | |AAEC 50.72(a) (1) (i) EMERGENCY DECLARED |MICHELE EVANS IRO | |ARPS 50.72(b)(2)(iv)(B) RPS ACTUATION - CRITICA|CHUCK CAIN R4 | |AESF 50.72(b)(3)(iv)(A) VALID SPECIF SYS ACTUAT|CHARLIE BAGWELL FEMA | | |JOHN FLACH NRC | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 M/R Y 100 Power Operation |0 Hot Standby | |2 M/R Y 100 Power Operation |0 Hot Standby | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | ALERT DECLARED | | | | 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. | | | | * * * UPDATE AT 0600 ON 4/24/03 FROM LICENSEE TO H. CROUCH * * * | | | | 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. | | | | * * * UPDATE AT 0718 ON 4/24/03 FROM DEAN BRUCK TO E. THOMAS * * * | | | | 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. | | | | * * * UPDATE AT 1020 ON 4/24/03 FROM TODD CASPER TO E. THOMAS * * * | | | | 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.
