| "Water Leak in Burnable Absorber Expansion System Modcon Area January 6, |
| 2002 |
| |
| "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 that the roofs over the moderation control (Modcon) area in the erbia |
| blending area had developed a small water leak. |
| |
| |
| "As Found Condition |
| A summary of the as found conditions is as follows: |
| * No operations were being performed in the erbia blending area. |
| * The leak was small trickle of water that ran down a structural I-beam and |
| puddled onto the floor. |
| * The water was not dripping onto any process equipment. |
| * The erbia blender was empty (contained no SNM), and the blender and all |
| bulk containers were tightly closed. |
| * The leak stopped by approx. 17:00 hours. |
| * The total amount of leakage was approx. 2 gallons (7.6 liters)of water |
| over approx. 5 hours. |
| |
| "Double Contingency Protection |
| Double contingency protection for the erbia blender and bulk containers is |
| based on moderation control (prevent greater than 20.48 liters of water |
| equivalent from entering blender/container). It was determined that double |
| contingency protection remained for the system. It is also noted that at no |
| time was greater than the safety limit of moderator involved. Therefore the |
| incident does not technically require notification in accordance with |
| Westinghouse Operating License (SNM-1107), paragraph 3.7.3. However, the |
| decision was made to provide this notification since it was considered to be |
| a serious 'near miss'. |
| |
| "Summary of Activity |
| * The incident was discussed thoroughly between the Team Manager and thc |
| NCS engineer by phone as soon as the leak was discovered. |
| * The NCS engineer made the preliminary determination that double |
| contingency protection remained. |
| * The NCS engineer then came to the plant, inspected the area of the leak |
| with Operations, applied the incident to the previously documented fault |
| tree analysis of the system, and confirmed that double contingency |
| remained. |
| |
| "Conclusions |
| * Loss of double contingency protection did not occur. |
| * Partial degradation of the controls did occur. |
| * Detection and corrective actions were effective in preventing ~y water |
| from becoming available to the blender or bulk containers. |
| * At no time was greater than a safe limit of moderator involved. |
| * 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. |
| * The Incident Review Committee (IRC) determined that this is a safety |
| significant incident in accordance with governing procedures. An apparent |
| cause analysis will be performed." |
