ALERT DECLARED DUE TO TOXIC GAS BUILD UP FOLLOWING AN EMERGENCY DIESEL GENERATOR TEST RUN

On April 25, 2012 at 2106 CDT, Point Beach Nuclear Plant declared an Alert under EAL HA3.1 due to toxic gas in a vital area. During a maintenance run on the plant's emergency diesel generator, diesel exhaust caused the concentration of carbon monoxide in an adjacent vital area room (Plant Instrument Air Compressor Room) to exceed OSHA IDLH (Immediately Dangerous to Life and Health) levels. The diesel was immediately secured and the room was ventilated. There were no personnel injuries and no public health and safety issues associated with this event.

The licensee notified the NRC Resident Inspector.

Notified DHS SWO, FEMA, USDA, DOE, DHS NICC, HHS AND EPA.

NOTIFICATION TO OFFSITE AGENCIES DUE TO OIL SPILL

"At 2246 EDT on April 25, 2012, D.C. Cook notified the State of Michigan and local authorities of an oil spill from the Unit 2 [Main Generator] Seal Oil system at 2110 EDT which resulted in a portion of this oil entering the absorption pond, which is in the owner controlled area. An oil sheen is present on the absorption pond which has a surface area of approximately 2 acres (87,000 square feet) and it is estimated that five to ten gallons of oil are on the absorption pond.

"The NRC Resident Inspector was notified."

The licensee has contained the oil leak and clean up efforts are ongoing.

PRESS RELEASE ISSUED FOR SHUTDOWN OF UNIT 2 DUE TO SALP INFLUX

"On April 25, 2012, at 2227 PDT, Diablo Canyon Power Plant (DCPP) U2 was manually taken offline and the reactor shut down due to an influx of sea salp - a small, jellyfish-like organism - in the intake structure. Operators manually started the auxiliary feedwater pumps in accordance with the plant operating procedures.

"PG&E will not restart Unit 2 until conditions improve at the intake structure. As previously announced, Unit 1 was safely shut down for a planned refueling and maintenance outage.

"All systems operated as designed and no unexpected equipment performance issues were noted.

"The licensee notified the NRC Resident Inspector."

The licensee plans on issuing a press release.

OFFSITE NOTIFICATION DUE TO DEATH OF A BALD EAGLE

"At 0955 [EDT] on April 26, 2012, a bald eagle (bird of prey) caused a phase to phase fault on the Station's 428 power line (power to buildings outside the protected area). The fault temporarily de-energized the 428 line. The bald eagle was found dead beneath the power lines.

"Two outside agencies, The Virginia Department of Game and Inland Fisheries and The U.S. Fish and Wildlife Service will be notified.

"This is being reported pursuant to 10 CFR 50.72(b)(2)(xi) for an event that required notification of other government agencies.

VALID ACTUATION OF THE REACTOR PROTECTION SYSTEM DURING TESTING

"At 1012 EDT on April 26, 2012, during the Reactor Pressure Vessel Hydrostatic Test, a valid high pressure reactor scram occurred due to issues related to controlling pressure near rated values. This actuation of the Reactor Protection System was not part of the pre-planned testing sequence. All control rods were fully inserted at the time of the scram. This report is being made in accordance with 10CFR50.72 (b)(3)(iv)(A), 'Any event or condition that results in valid actuation of any of the systems listed except when the actuation results from and is part of a pre-planned sequence during testing or reactor operation.' The reactor scram was reset after reactor pressure was lowered."

The licensee has notified the NRC Resident Inspector.
