REMAINS DISCOVERED OUTSIDE OCA

"On June 9, 2009 at approximately 1200 CDT, remains not yet identified as human or animal were found by Prairie Island Nuclear Generating Plant (PINGP) employees. The remains were discovered on Xcel Energy property just outside the PINGP owner controlled area along the transmission line path, near the railroad tracks.

"The Red Wing City Police Department and the Prairie Island Indian Community Police Department have both been notified and are on the scene. Notifications are being made to appropriate agencies and officials. No press release is planned."

The licensee has notified the NRC Resident Inspector. The licensee is treating this as a media sensitive event.

* * * UPDATE FROM L. PASCHKE TO HOWIE CROUCH @ 2026 EDT ON 6/9/09 * * *

The licensee reported that the Prairie Island Police, Red Wing City Police and the Minnesota Bureau of Criminal Apprehension have cleared the scene after they determined that the remains were that of a large bird. There has been no intense media interest at this time.

Notified R3DO (Pelke), HQPAO (Brenner) and ILTAB (Allston).

DOOR FOR SECONDARY CONTAINMENT BOUNDARY LEFT OPEN

"This notification is being made pursuant to NRC regulation 10 CFR 50.72(b)(3)(v)(D), any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.

"At 1852 [CDT] on June 9, 2009, River Bend Station personnel discovered that a normally closed auxiliary building door was open. This door serves as part of the secondary containment boundary. At discovery, immediate action was taken to close the door. This action restored the secondary containment to the design configuration. Investigation determined that the door was last accessed at 1242 on June 9 and was most probably left open at that time. Further action is being taken to investigate the cause of the event.

"Secondary containment leak tightness is required to ensure that the release of radioactive materials from the primary containment is restricted to those leakage paths and associated leakage rates assumed in the accident analysis, and that fission products entrapped within the secondary containment structures will be treated by the Standby Gas Treatment System prior to discharge to the environment. With the subject door being open, the function of secondary containment would be impacted. A second door is located in the same exterior passage way as the secondary containment door found open. This door was closed during the period of time the secondary containment door was open. This second door serves a security function. However, it potentially could serve to perform the secondary containment function. An evaluation is being performed to determine the actual impact of the condition on the secondary containment function. However, based on the identified condition, this report is being made as a condition that could have prevented fulfillment of a safety function."

The licensee has notified the NRC Resident Inspector.
