| 24 HOUR 91-01 BULLETIN RESPONSE |
| |
| Reason for Notification |
| |
| At the time of the event, the Team Leader of the Burnable Absorber Expansion |
| System called the cognizant Nuclear Criticality Safety (NCS) engineer to |
| inform him that 113.5 kg of uranium oxide powder had spilled from process |
| equipment into the granulator hood. |
| |
| |
| Summary of Process |
| |
| Dry UO2 powder blended with U3O6 and erbium oxide is processed in a |
| favorable geometry, gravity fed, vertical pipe from a roll compactor down to |
| a granulator. Inside a hood, the granulator feeds down through a flexible |
| tube into a polypak. |
| |
| |
| As Found Condition |
| |
| A summary of the as found conditions is as follows: |
| |
| It had been determined that the granulator screen needed to be replaced, and |
| operations were stopped. |
| |
| When the granulator screen was removed, material in the vertical pipe |
| spilled down onto the bottom of the hood, remaining contained within the |
| hood. |
| |
| The spill was immediately placed into polypaks and telephone notification |
| was made to Nuclear Criticality Safety. |
| |
| |
| Double Contingency Protection |
| |
| Double contingency protection for this situation, which is classified as a |
| spill, is based on control of mass and moderation, and assumes a |
| hemispherical configuration. The mass limit is 50.3 kgU or 57.1 kg UO2; the |
| moderator limit is 32.1 liters of water. It was determined that double |
| contingency protection was lost because the amount of material spilled |
| exceeded the mass limit. |
| |
| Moderation controls remained intact. Double contingency protection was |
| restored in approximately 30 minutes. Therefore the incident requires |
| notification in accordance with Westinghouse Operating License (SNM-107), |
| paragraph 3.7.3 (c.5), in which greater than safe mass is involved, but |
| controls are restored within four hours. |
| |
| |
| Summary of Activity |
| |
| Nuclear Criticality Safety gave permission to resume operations because |
| double contingency protection had been restored. |
| |
| On January 28, 2002, written instructions were issued to erbia operations |
| personnel and training conducted reinforcing that before removal of the |
| screen from the granulator, the material in the vertical process pipe is to |
| be processed into polypaks. |
| |
| Long term corrective actions to prevent the possibility of recurrence will |
| be evaluated as part of apparent cause analysis. |
| |
| |
| Conclusions |
| |
| Loss of double contingency protection did occur, but was restored within |
| approximately 30 minutes. |
| |
| At no time was criticality possible because there was no moderator present. |
| |
| At no time was there any risk to the health or safety of any employee or |
| member of the public. No exposure to hazardous material was involved. |
| |
| It has been determined that this is a safety significant incident in |
| accordance with governing procedures. An apparent cause analysis will be |
| performed. |

| OFFSITE NOTIFICATION OF AN OIL SPILL |
| |
| A spill of approximately 40 gallons of turbine lube oil in the turbine hall |
| occurred with no release to the environment. This amount was in excess of |
| the reportable quantity of 10 gallons, so notification was made to the |
| Connecticut Department of Environmental Protection of the spill. This |
| incident occurred during a decommissioning activities in the turbine hall. |
| |
| The NRC Resident Inspector was notified. |
