| LEGACY ISSUE |
| |
| NRC BULLETIN 91-01 24 HOUR NOTIFICATION |
| |
| "AT 1313 CST, on 1-30-02 the Plant Shift Superintendent (PSS) was notified |
| of uncharacterized legacy process equipment which was not stored in |
| accordance with an approved Nuclear Criticality Safety Approval (NCSA). The |
| mass of fissile material was less than a safe mass and at an assay of less |
| than 2.0 Wt. %. This is in violation of the NCS program requirements of |
| SAR, Section 5.2 which requires fissile material operations to be controlled |
| by approved NCSA's. |
| |
| "The PSS determined that this event is a 24 Hour Event Report due to the |
| failure to maintain double contingency controls. |
| |
| SAFETY SIGNIFICANCE OF EVENTS: |
| |
| "This material is in a stable condition and double contingency has been |
| established using approved procedures. Once the material was characterized, |
| it was determined that proper spacing had been maintained. |
| |
| POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO(S) OF HOW |
| CRITICALITY COULD OCCUR): |
| |
| "In order for criticality to be possible more than a critical mass would |
| need to be accumulated in an unsafe geometry. The storage containers are |
| safe by geometry and the fissile material is less than a safe mass. |
| Therefore, it is not possible for this barrier material to result in a |
| criticality accident. |
| |
| CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY, CONCENTRATION,
ETC.): |
| "Mass |
| |
| ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE
PROCESS |
| LIMIT AND % WORST CASE CRITICAL MASS): |
| |
| "Less than 10 pounds at an enrichment of less than 2.0 Wt. % |
| |
| NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND
DESCRIPTION |
| OF THE FAILURES OR DEFICIENCIES: |
| |
| "Since no NCS controls were applied to the material, double contingency |
| cannot be demonstrated. |
| |
| CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEMS AND WHEN EACH WAS
IMPLEMENTED: |
| |
| "The material is controlled in accordance with procedure CP-2-TS-TS2030. |
| The material has been characterized." |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |

| OVEREXPOSURE |
| |
| The film badges of two radiographers working for H& H X-Ray Services were |
| processed for the month of October, 2001. The readings of the film badges |
| for the month of October were 7909 mrem and 3825 mrem. H & H X-Ray Services |
| individuals were using a 68 curie (Iridium-192) radiography camera in |
| Monroe, LA. The State of Mississippi Division of Radiation Health is |
| following up on this report. |

EVENT TEXT

| LOSS OF 6 EMERGENCY SIRENS DUE TO ICE STORMS |
| |
| AT 1345 it was determined that six of their eleven emergency plant sirens |
| were not operational. An ice storm caused the loss of power to the sirens. |
| The county sheriffs office was contacted and in the event of an actual |
| emergency they will contact personnel in these areas directly (route |
| alerting). The remaining five sirens will alert a majority of the |
| population in the effective ten mile zone. The total ten mile zone is |
| approx. 6099 persons. |
| |
| The remote telemetry system used to identify siren failures did not function |
| correctly. We determined that at least one siren was unavailable and this |
| information was unavailable from the normal monitoring method. A backup |
| method was used to determine the extent of the problem. |
| |
| A news statement was issued to the public at approximately 1600 hours, |
| 01/31/02, discusses the loss of the six emergency sirens. |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |
