| Title | Nrc Bulletin 91-01 - 4 Hour Report |
| Event Description | The following was submitted via email:
Reason for Notification A canvas lined cart was found in the UF6 [Uranium Hexafluoride] bay. The cart dimensions met the criteria for a non favorable geometry [NFG] container however slits had been cut into the bottom of the cart. The presence of the slits makes it questionable as to whether or not this is a true NFG. Taking a conservative approach and assuming that the cart is an NFG, its presence in the Chemical area is prohibited by SNM-1107, Section 6.1.4 without a nuclear criticality safety analysis. In accordance with Westinghouse Operating License (SNM-1107), paragraph 3.7.3 (b.2), this event satisfies the criteria for a 4-hour notification. Specifically, any determination that a criticality safety analysis or evaluation was deficient, or that a particular system was not previously analyzed; and that less than two unlikely, independent, and concurrent changes in process conditions would be required before a criticality accident would be possible. As Found Condition An NCS [Nuclear Criticality Safety] Engineer was notified by a member of the EH&S [Environmental Health and Safety] Department that a canvas cart was in the UF6 bay. The canvas cart had several slits approximately five inches in length cut in the bottom that would preclude the build-up of liquid materials. There was no process equipment in the general area where the cart was located. There was no SNM [Special Nuclear Material] in the cart and the cart was not a part of any existing process. Summary of Activity -The cart was dismantled immediately. -NCS notified NRC Region II of the cart. Conclusions -This particular system was not previously analyzed for criticality safety. -There was no SNM involved. -At no time was the health or safety to any employee or member of the public in jeopardy. No exposure to hazardous material was involved. -The Incident Review Committee (IRC) has determined that this is a safety significant incident in accordance with governing procedures. -A causal analysis will be performed. The Licensee notified Region 2 (Ayres, Crespo). |
