' " | | | | "While performing an Essential Service Water (ESW) surveillance test on Unit | | 2, it was noted that the ESW flow to each Diesel Generator was abnormally | | low. This condition could have prevented the Diesel Generators from | | fulfilling their safety function. This condition was caused by sand and | | sediment in the ESW system and impacted both units." | | | | "Subsequent system flushes and valve cycling [have] eliminated the low flow | | condition in both Unit 1 and 2 Diesel Generators." | | | | "We will continue to monitor ESW system performance. Further investigation | | of this event is in progress to determine the root cause of the low flow | | anomaly." | | | | "Unit 2 will be [shutting] down [and] going to [Cold Shutdown] beginning in | | the next 3 hours." (Refer to event #38253 for additional information.) | | | | The licensee plans to notify the NRC resident inspector. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |General Information or Other |Event Number: 38250 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: TEXAS DEPARTMENT OF HEALTH |NOTIFICATION DATE: 08/30/2001| |LICENSEE: WASHINGTON GROUP INTERNATIONAL, INC. |NOTIFICATION TIME: 10:34[EDT]| | CITY: BAYTOWN REGION: 4 |EVENT DATE: 08/23/2001| | COUNTY: STATE: TX |EVENT TIME: [CDT]| |LICENSE#: TX 02662-004 AGREEMENT: Y |LAST UPDATE DATE: 08/30/2001| | DOCKET: |+----------------------------+ | |PERSON ORGANIZATION | | |GAIL GOOD R4 | | |JOHN HICKEY NMSS | +------------------------------------------------+ | | NRC NOTIFIED BY: JAMES H.

Event Description[: ...] On August 23, 2001, the licensee notified | | the Agency of a damaged radiographic camera which occurred on July 26, 2001. | | The device, containing 43 curies of Iridium-192, was damaged by a | | radiographer applying excessive force to the selector ring while attempting | | to connect the drive assembly. The device was returned to [its] | | transportation overpack and returned to storage as damaged. After | | disassembly, cleaning, and inspection, no visual signs of damage were | | detected and the gauge was reassembled. Upon reassembly, it was noted that | | there was play in the selector ring. A new storage cover was installed and | | the camera was returned to service. To prevent a recurrence: the | | radiographer involved was retrained on the equipment and informed to | | immediately notify the radiation safety officer of damaged equipment; both | | radiographers were reprimanded for failure to follow company Operating, | | Safety, and Emergency Procedures; all other exposure devices were inspected | | to see if the same problem existed - none exhibited this problem; this | | incident was discussed at the licensee's biweekly safety meeting; and the | | 'old' device cover was sent for evaluation. No abnormal exposures were | | detected as a result of this incident." | | | | (Call the NRC operations officer for state contact information.) | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 38251 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: MONTICELLO REGION: 3 |NOTIFICATION DATE: 08/30/2001| | UNIT: [1] [] [] STATE: MN |NOTIFICATION TIME: 11:50[EDT]| | RXTYPE: [1] GE-3 |EVENT DATE: 08/30/2001| +------------------------------------------------+EVENT TIME: 09:58[CDT]| | NRC NOTIFIED BY: PFEFFER |LAST UPDATE DATE: 08/30/2001| | HQ OPS OFFICER: CHAUNCEY GOULD +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: NON EMERGENCY |JOHN MADERA R3 | |10 CFR SECTION: | | |ACOM 50.72(b)(3)(xiii) LOSS COMM/ASMT/RESPONSE| | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N Y 100 Power Operation |100 Power Operation | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | LOSS OF OFFSITE RESPONSE CAPABILITY | | | | The loss of the Public Prompt Notification System(PANS) was discovered | | during the performance of a surveillance test. | | The Wright County Civil Defense was notified and is standing by to perform | | route alert if necessary. | | | | | | The NRC Resident Inspector will be notified along with state and local | | agencies. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Other Nuclear Material |Event Number: 38252 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: DOMINION |NOTIFICATION DATE: 08/30/2001| |LICENSEE: DOMINION GENERATION |NOTIFICATION TIME: 11:55[EDT]| | CITY: MT.

Storm coal generating station. The gauge contains 100 | | mCi of Cs-137 and was purchased under a general license. The vendor notified | | the Mt. Storm facility on 8/3/2001 that the gauge had never been returned. | | The gauge was last inventoried in August of 1982.

At 1248 on | | 8/30/01, more than one IRPI per group became inoperable which is beyond Cook | | TS 3.1.3.2. Action statement. This would require entry into TS 3.0.3 which | | requires initiating action within one hour to place the unit in a mode in | | which the specification does not apply. At that time Unit 2 was in mode | | 2@3.3% power and was expected to enter mode 3 at which time 3.1.3.2 would no | | longer be applicable. At 1347 the unit was shut down in mode 3 and exited | | both TS 3.1.3.2 and 3.0.3. | | | | The NRC Resident Inspector was notified. | +------------------------------------------------------------------------------+
