Three items from this morning’s NRC Event Reports page:
1. On Friday morning, an employee supervisor at the Grand Gulf nuclear power plant failed a random Fitness for Duty screening. Test results showed the presence of prohibited drugs in the supervisor’s blood. The employee’s access to the plant has been terminated.
2. Also on Friday morning, an employee at the Vermont Yankee nuclear power plant had been instructed to shut down the ‘B’ diesel generator serving the Unit 1 reactor. The employee entered the ‘A’ diesel generator room and took the only working generator out of service. This resulted in a control room alarm due to both generators being inoperable.
3. And on Saturday afternoon, an operator on rounds at the Millstone nuclear power plant in Connecticutt discovered that a door seal had failed in the Secondary Containment Enclosure Building. This caused plant owner Dominion to report the event “as a condition that could have prevented the fulfillment of the safety function to control the release of radioactive material.”
