| Title | Gap Discovered in Control Room Envelope |
| Event Description | During Control Room Boundary investigations a gap in the control room envelope was discovered that exceeded the assumptions of the plant toxic gas analysis. The assumptions for the control room radiological analysis were met with the consideration for the use of Kl. The gap size was determined to be approximately 103 square inches versus an analysis assumption of 58.9 square inches. The gaps were immediately repaired.
The licensee suspects that the gap has existed for 20 or more years and was discovered during a control room heating, ventilation, air-conditioning (HVAC) upgrade. The license has notified the NRC Resident Inspector of this event. |
