AGREEMENT STATE REPORT - POTENTIAL PERSONNEL OVEREXPOSURE

The licensee's RSO received a phone call from Landauer at 1030 this morning to report a badge which had a deep dose reading of 6437 milliRem, an eye dose reading of 6437 milliRem, and a shallow dose reading of 6400 milliRem. The badge was assigned to the Chief of Surgery for the licensee for the month of January 2006. The RSO is investigating the cause for the fifteen month delay (January 2006 till June 2007) in processing the badge. Landauer told the RSO that this was a "dynamic" exposure to the badge meaning that the badge was moving during the time period of exposure.

Iowa Item Number IA-070001.

INVALID ESF ACTUATION DURING REFUELING OUTAGE

"This telephone notification is provided in accordance with 10 CFR 50.73(a)(1) to report an invalid Engineered Safeguards Feature (ESF) actuation of the Auxiliary Feedwater(AFW) system reportable under 10 CFR 50.73(a)(2)(iv)(A).

"On April 16, 2007, at 2223 with Unit 1 in Mode 3, starting up from refueling outage 18, the 11 Steam Generator Feed Pump (SGFP) trip AFW Pump Auto Armed light extinguished unexpectedly and the Steam Generator (SG) sample valves 11 through 14-SS94 and SG Blowdown valves 11 through 14-GB4 closed. At the time, the 11 and 12 SGFPs were already tripped and the 11 and 12 Auxiliary Feedwater pumps were in service. No control room manipulations were in progress. A signal was generated to start the already in service AFW pumps.

"The invalid signal to start the AFW pumps was determined to be from a faulty SGFP alternate trip relay. The defective relay was replaced and the isolation signal was reset and retested satisfactorily.

"This event is reportable under 10 CFR 50.73(a)(2)(iv)(A) as an invalid ESF actuation and invalid system actuation.

"The licensee notified the NRC Resident Inspector."
