Event Notification Report for April 24, 2009

AUTOMATIC REACTOR TRIP DURING INSTRUMENT CALIBRATION

"At 1141 CT, Braidwood Unit 2 experienced an automatic Reactor Trip. The Reactor Trip red first out annunciator was Over Temperature Delta Temperature (OTDT). At the time of the Reactor Trip the Instrument Maintenance Department was performing a scheduled calibration of a Pressurizer Pressure channel (2PT-456) which is in the B loop of reactor protection. During the calibration a spike occurred on the D loop of reactor protection. Specifically, the RCS [Reactor Coolant System] temperature for the D loop. This caused a Reactor Trip on a 2 of 4 coincidence.

"After the reactor trip occurred, all four steam generators reached their low-2 Reactor Trip setpoints and pressurizer pressure reached its low pressure Reactor Trip setpoint all of which is an expected response on a trip from full power. Steam Generator levels and Pressurizer pressure have been restored. Both the 2A and 2B Auxiliary Feedwater pumps auto started on the low-2 steam generator levels as expected. All control rods fully inserted into the core.

"No secondary relief valves lifted and no secondary steam released as a result of the Reactor Trip. Steam Generators are now being filled by the 2A Main Feedwater pump and the Auxiliary Feedwater pumps have been placed in standby. The main steam dumps are in service to the main condenser to provide heat sink cooling. The plant is being maintained at normal operating pressure and temperature.

"This report is being made per 10 CFR 50.72(b)(2)(iv)(B) for RPS actuation, 4 hour notification, and per 10 CFR 50.72(b)(3)(iv)(A) for automatic actuation of the Auxiliary Feedwater System, 8 hour notification.

"The electrical line up transferred to the normal shutdown configuration with the standby diesel generators and safety systems available. There is no Unit 1 impact.

"The licensee plans on issuing a press release and has notified the NRC Resident Inspector."

AGREEMENT STATE REPORT - LOST STATIC ELIMINATOR

"On April, 23, 2009, the Virginia Department of Health (VDH) was notified by Virginia Commonwealth University (VCU) that a Nuclear Radiation Developments, Inc. 'Ionotron' containing an Am-241 source has been lost. The source is a model number A-001 with an activity of 20 microcuries on 12/75.

"The source was last inventoried on February 27, 2009. Since then, VCU began to clean up this storage location and placing unwanted material in a barrel for disposal through RSO, Inc. The barrel was picked up on April 1, 2009.

"VCU found the source missing when they went to take a picture for its disposal through the SCATR program. It is believed that the source was placed into the barrel and has been disposed of by RSO, Inc.

"VCU will submit the 30 day written report to VDH."

This report is VA number: VA-09-01.

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

AGREEMENT STATE REPORT - TWO MISSING GENERAL LICENSED DEVICES

The following information was received via facsimile from the Alabama Office of Radiation Control:

"On the morning of April 24, 2009 at approximately 1120 am CDT, the Alabama Office of Radiation Control received a phone call from representatives of BF Goodrich in Tuscaloosa, Alabama advising the [State] Agency of the discovery of two missing general licensed devices containing radioactive material. The representatives of BF Goodrich indicated that on April 23, 2009, two NDC model 103 profile gauges containing 150 millicuries each of Am-241 were discovered to be missing. The gauges were installed at the facility but had not been in use for an extended period of time. The shutter for each of the devices were reported as closed. The serial numbers reported were 13311 and 13312. The gauges were possessed and used under a general license registration. Representatives of BF Goodrich continue to investigate the incident and will provide a written report within 30 days."

REPORT INVOLVING THERAPEUTIC ADMINISTRATION OF I-131 TO PATIENT IN EARLY PREGNANCY

On 4/24/09 at approximately 1400 hours, a female patient undergoing treatment for hyperthyroidism received a 12.1 millicuries dose of I-131. She had completed both a questionnaire and lab test indicating that she was not pregnant prior to receiving treatment. Subsequent to the administration, she learned she had conceived approximately 2-3 days prior to treatment. This information was provided to hospital staff on 6/16 at which time an evaluation for potential adverse consequences was initiated.

The licensee discussed this issue with NRC Region IV staff (Leonardi).

* * * RETRACTION FROM LOWELL HUSMAN TO JOE O'HARA AT 1242 EDT ON 6/18/09 * * *

The licensee is retracting the event report because they believe the dose to the embryo is less than the limit specified in 10CFR35.3047(a).
