| 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. |

| CONTROL ROOM VENTILATION SYSTEM DECLARED INOPERABLE |
| |
| 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. |
| |
| The licensee notified the NRC Resident Inspector. |
