"At 03:47 on 12/28/07, during plant start up from a refueling outage while in Mode 2, one control element assembly (CEA) dropped to the bottom of the core from the upper electrical limit. The reactor was not critical at the time. Technical Specification LCO 3.1.3.1 [Action E] was initiated to proceed to Mode 3 at 0450 while actions were taken to repair and retrieve the CEA. This event was reported as a four hour non-emergency report pursuant to 10CFR 50.72(b)(2)(i), 'The initiation of any nuclear plant shutdown required by Technical Specifications.' Upon further review of the event, and since the Unit was not critical in mode 2 at the time of the event, this event is not considered reportable in accordance with the guidance provide in NUREG-1022, Rev. 2, 'Event Reporting Guidelines 10CFR50.72 and 50.73,' in which 'The initiation of any plant shutdown' does not include mode changes required by TS if initiated after the plant is already in a shutdown condition. As such this notification is being retracted. The Site Resident has been notified of this retraction." |

"At 0758 CDT, on March 26, 2008, the Goodhue County dispatcher inadvertently activated the Goodhue County sirens from the primary unit during the conduct of a silent siren test. As per procedure they were to send out two silent signals; however the first was the silent and the second signal was the activation. Upon selecting the alert, they immediately sent out a signal to cancel the activation. Thirty-two of the 117 sirens in the 10-mile Emergency Planning Zone (EPZ) were activated for approximately 14 seconds. The licensee was notified of the siren activation by the activation signal received on the informer unit in the Technical Support Center (TSC) as well as hearing the sirens being activated. Goodhue County Emergency Management contacted the local radio station at 0805 [hrs. CDT] to notify the public of the false activation. No press release is planned by Xcel Energy. No other press release is planned by Goodhue County."

"On March 26, 2008, at approximately 11:07 hours, an oil sheen was discovered outside the Indian Point cooling water discharge canal in the Hudson River. In accordance with the Indian Point Spill/Release plan, a spill or leak causing a visible sheen in the river as a result of the release of a petroleum product requires a notification to the New York State Department of Environmental Conservation (NYS DEC) and the National Response Center (U.S. Coast Guard). The National Response Center was notified at 11:16 hours and the NYS DEC was notified at 11:38 hours. The source and cause of the petroleum product spill/leak is under investigation. An environmental cleanup vendor was contacted and is scheduled to be on site the afternoon of March 26, 2008, for assessment and cleanup."

"At 1045 EDT, it was recognized that Auxiliary Building Door R5-6 is a Control Center Pressure Boundary door. The door was blocked open at approximately 1400 on 3/24/2008 to support draining for on going maintenance on Division 1 CCHVAC Chiller. Upon recognizing this condition, Tech Spec 3.7.3 Action B.1 was entered for an inoperable Control Center Pressure Boundary at 1045 EDT [03/26/2008], with a 24 hour action to restore the boundary to operable status. Actions were taken to close Door R5-6 at 1120 hours [03/26/2008], and Tech Spec 3.7.3 Action B.1 was exited. This event is being reported per 10CFR50.72(b)(3)(v) as a condition that at the time of discovery could have prevented the fulfillment of the safety function of the Control Room Emergency Filtration (CREF) system. The accident mitigation function of CREF could not be assured during the time Door R5-6 was open without administrative controls to close it, if necessary."

"At 1410, on 3/26/08 the Plant Shift Superintendent was notified that a violation of a nuclear criticality safety approval (NCSA) had occurred. During a review of pre-removal NDA [Non destructive assessment] inspection in C-337 for the unit 3 cell 10 stage 2 converter inspection port, it was discovered that the NDA was performed on the wrong side of the converter (measurement taken on the east side of the converter, and the access hole was cut in the west side). The pre-removal NDA inspection was improperly performed resulting in a violation of NCSA GEN-10. The purpose of the requirement is to determine the initial handling category of the equipment.
"Two independent post removal NDA measurements were performed on the adjacent system and two independent visual inspections were performed on the removed item that demonstrated the item and adjacent system were each UH [uncomplicated handling]. The results indicate the equipment was properly classified as UH based on the resulting mass.
"SAFETY SIGNIFICANCE OF EVENTS: Although a leg for double contingency was lost, the correct equipment handling category was used. Additionally, an independent verification of no visible uranium present on the removed item has been successfully performed in accordance with applicable procedures to NCS Exempt the item.
"POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO(S) OF HOW CRIT!CALITY COULD OCCUR): The equipment contained less than a safe mass of uranium and the equipment was covered to prevent exposure to a moderator. The uranium mass would have had to exceed a critical mass. The equipment would then need to be exposed to sufficient moderator in order for a criticality to be possible.
"CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY CONCENTRATION, ETC.): The process condition relied on for double contingency for this scenario is mass.
"ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS LIMIT AND % WORST CASE CRITICAL MASS): The NDA measurement indicated less than 674 grams at 1.6679 wt% U-235.
"NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION OF THE FAILURES OR DEFICIENCIES: The first leg of double contingency relies on mass. Prior to opening the system a pre-removal NDA is required to be performed to initially classify the handling category of the equipment. Since the pre-removal NDA was performed on the wrong side of the equipment potentially resulting in an improper handling categorization, this control was violated. The second leg of double contingency is based on mass by performing a post-removal NDA of the removed equipment and adjacent system within 24 hours to verify the handling category. This control was not violated.
"CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEMS AND WHEN EACH WAS IMPLEMENTED: On 3/26/08, a second post removal NDA was completed on the adjacent system and a second visual inspection was performed on the removed item in order to verify the handling category is UH and re-establish double contingency.
