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. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 38657 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: HADDAM NECK REGION: 1 |NOTIFICATION DATE: 01/28/2002| | UNIT: [1] [] [] STATE: CT |NOTIFICATION TIME: 17:39[EST]| | RXTYPE: [1] W-4-LP |EVENT DATE: 01/28/2002| +------------------------------------------------+EVENT TIME: 16:00[EST]| | NRC NOTIFIED BY: HOUFF |LAST UPDATE DATE: 01/28/2002| | HQ OPS OFFICER: CHAUNCEY GOULD +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: NON EMERGENCY |CURTIS COWGILL R1 | |10 CFR SECTION: | | |APRE 50.72(b)(2)(xi) OFFSITE NOTIFICATION | | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N N 0 Decommissioned |0 Decommissioned | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | 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. | +------------------------------------------------------------------------------+
