| Event Text FAILURE OF A RADIOGRAPHIC CAMERA LOCKING MECHANISM
The following information is from a letter that was sent to the NRC:
"During an NRC inspection it was brought to our attention that we are required by 10CFR 34.101 to notify the Nuclear Regulatory Commission of any failure of a radiographic device or a component critical to the safe operation of the device to properly perform its intended function. The following is the information requested in 10CFR 34.101.
"1. The key mechanism would not lock on a 660B Tech Ops Camera.
"2. The failure of the locking mechanism is not known by us.
"3. The manufacture of the equipment is AEA Technology QSA, Inc., Burlington, MA.
"4. The place was Anchorage, Alaska and the date 7/23/2003.
"5. The action taken to establish normal operations is ship the camera back to AEA Technology QSA and have them fix the lock mechanism when we need and additional camera. The iridium source was transferred to a IN Model IR-50 source changer and shipped to Industrial Nuclear for disposal. The camera at this time is empty and awaiting a time when we would need an additional camera. We have four operational cameras and do not have a need for this camera anytime in the foreseeable future.
"6. We plan to have AEA Technology QSA repair the lock mechanism.
"7. (Deleted) President of Alaska Industrial X-ray a former RSO and radiographer took the above action to prevent any over exposure to our personnel." |

"On September 7, 2006 at 2157 hours, Beaver Valley Power Station Unit No. 1 was operating at 100% when an automatic reactor trip occurred following a spurious opening of the 'B' Reactor Trip Breaker. The first-out indication for the reactor trip was turbine trip due to reactor trip.
Control room personnel entered Emergency Operating Procedure E-0, 'Response to Reactor Trip and Safety Injection.' Safety systems and equipment functioned as designed following the automatic reactor trip. Reactor pressure and temperature have been stabilized following the reactor trip without requiring a Safety Injection. The plant was stabilized in Mode 3 utilizing the normal heat sink (main condenser) with steam generator levels restored to post shutdown values by the Auxiliary Feedwater System. All normal and emergency busses are energized from offsite power.
"The cause of the reactor trip is being investigated."
All rods fully inserted, all ESF systems remain operable, and the electrical grid is stable. The licensee notified the NRC Resident Inspector and plans to issue a press release. | |
