| POWER LOST TO BUILDING BEACON CRITICALITY ACCIDENT ALARM SYSTEM (CAAS).      |
|                                                                              |
| At 0350 hours on 06/23/01, it was discovered that the CAAS beacons for       |
| building C-333 were inoperable due to a loss of power.  The system is        |
| required to be operable according to TSR 2.4.4.2.b for the prescribed modes  |
| of operation.  Loss of power to the CAAS beacons occurred during the process |
| of returning auxiliary power transformers to service.  Power to the beacons  |
| was lost for a total of approximately 3 minutes.  Normal power was           |
| subsequently restored.  The building CAAS detectability and horn audibility  |
| were not lost due to the power failure.  No operations were taking place in  |
| building C-333 while the CAAS beacons were inoperable but fissile material   |
| is stored in the building.                                                   |
|                                                                              |
| The NRC Resident Inspector has been notified of this event by the            |
| certificate holder.                                                          |

| * * * RETRACTED AT 1630 EDT ON 7/9/2001 BY J. M. UNDERWOOD TO FANGIE JONES * |
| * *                                                                          |
|                                                                              |
| The following is taken from a faxed report:                                  |
|                                                                              |
| "The PSS's reporting determination was based on the fact that the CAAS       |
| lights are mentioned in the CAAS TSR 2.4.4.2b Basis Statement. The Basis     |
| includes a paragraph that describes the quarterly surveillance of the CAAS   |
| building horns and, in this paragraph, states that the test signal activates |
| the high radiation light and bell in C-300 and activates the building CAAS   |
| horns and lights. This is the only mention of CAAS lights in the CAAS TSR.   |
| This statement has been interpreted in the past as requiring the CAAS lights |
| to be available and operable and, when inoperable, requiring completion of   |
| the TSR 2.4.4.2b LCO actions and reporting to the NRC per 10CFR76.120        |
| (c)(2).                                                                      |
|                                                                              |
| "Since the subject event, NRA has reviewed the TSR, SAR. ANSI/ANS8.3, and    |
| 10CFR76 and noted the following:                                             |
| [1]  CAAS TSR 2.4.4.2b requires the CAAS to be operable (audible) and        |
| prescribes the required actions to be taken when the 'area does not have an  |
| audible criticality accident alarm'.  Audibility is proven by the building   |
| CAAS horns which were not affected by the subject power failure. There are   |
| no actions required for loss of the building lights.                         |
| [2]  Surveillance requirements 2.4.4.2b-1 and 2.4.4.2b-2 requires quarterly  |
| testing of the CAAS horns and verification that the CAAS air accumulator     |
| supply pressure to the building horns is adequate to sound the horns for at  |
| least 120 seconds.  There are no TSR surveillance requirements for the       |
| building lights.                                                             |
| [3]   ANSI/ANS8.3, 'Criticality Accident Alarm System'. Section 4.3 requires |
| audio alarm signals and Section 6.4 requires periodic tests of the signals.  |
| ANSI/ANS8.3 does not require or recommend visual alarm signals except in     |
| Section 4.3.8, where visual signals are recommended in areas of very high    |
| audio background or mandatory hearing protection, neither of which applies   |
| to areas outside the buildings with CAAS coverage.                           |
| [4]  PGDP SAR Section 5.2.2.4 states, 'a CAAS is provided to alert personnel |
| if a criticality accident should occur. The system utilizes a distinctive    |
| audible signal to notify personnel in the affected area and initiate         |
| evacuation...'.  There is no mention of the building lights.                 |
| [5]  10CFR76.89, Criticality Accident Requirements, requires USEC to         |
| maintain and operate a criticality monitoring and audible alarm system.      |
| There is no mention of building lights,                                      |
|                                                                              |
| "From the information provided, NRA has concluded that CAAS audibility is    |
| provided solely by the CAAS horns and is not affected by the loss of the     |
| CAAS lights. Thus, the CAAS building lights are not required to be available |
| and operable by the TSR and CAAS operability is not affected when the lights |
| are not functional. Since the lights are not required to be available and    |
| operable by the TSR, the reporting requirement of 10CFR76.120 (c)(2) is not  |
| met and reporting is not required. In addition, the TSR LCD actions          |
| prescribed by TSR 2.4.4.2b do not apply to the CAAS lights and are not       |
| required to be implemented. Based on this information, the subject NRC event |
| notification (PAD.01-023) is being retracted."                               |
|                                                                              |
| The licensee notified the NRC Resident Inspector.  The R3DO (David Hills)    |
| and the NMSS EO (Eric Leeds) have been notified.                             |

| The Division 2 Main Control Room Ventilation System was declared inoperable  |
| at 0900 CDT on 7/9/2001 because it was not maintaining the required positive |
| pressure while running in the High Radiation Mode of operation.  The system  |
| was declared operable at 0913 CDT when the required positive pressure was    |
| restored.  During the 13 minute period Division 2 was inoperable, Division 1 |
| Main Control Room Ventilation System was inoperable due to a scheduled       |
| maintenance outage.  Therefore, with both systems inoperable, a condition    |
| existed which could have prevented the fulfillment of the safety function of |
| the Main Control Room Ventilation System needed to mitigate the consequences |
| of an accident.  The cause of the perturbation in control room pressure is   |
| being investigated.                                                          |
