AGREEMENT STATE REPORT - FETAL EXPOSURE IN EXCESS OF 500 MILLIREM DURING A PET/CT SCAN

The following information was obtained from the State of Colorado via facsimile:

"The Department received notification on March 23, 2010, of a fetal exposure in excess of 500 milliRem from a PET/CT Scan. The licensee, PET Imaging of Northern Colorado, License No. 1105-0, is located in Fort Collins, Colorado. The licensee reported that on December 14, 2009, a female patient received 17.4 mCi of F-18 and underwent a PET/CT scan. The patient had indicated that she was not pregnant on her medical history questionnaire and told the technologist she was not pregnant prior to the scan. Later, the patient's physician notified the licensee that the patient was indeed pregnant at the time of the scan.

"A consulting medical physicist calculated the total dose to the fetus from the PET/CT scan as 2.6 Rem (26 mGy). However, the medical physicist did not report the individual dose from the F-18 component alone, and this information has been requested from the licensee.

"The licensee's authorized user physician reported that the risk of abnormality for the fetus is considered to be negligible per the guidance from the American College of Radiology Practice Guidelines.

"No other details are available at this time."

PRESS RELEASE DUE TO LUBE OIL FIRE AFFECTING REACTOR FEED PUMP

"At 1818 , the control room was notified of a lube oil fire on Reactor Feed Pump Turbine B. The fire brigade was toned out, and the Perry Township Fire Department was notified for assistance. Reactor Feed Pump Turbine B was manually tripped to allow removing the turbine lube oil system from service. The Motor Feed Pump started as expected, and the Reactor Recirculation system lowered reactor power as designed. Currently the reactor is at 68% reactor power following rod line adjustments after the transient was complete.

"The fire was reported to be out by the fire brigade leader at 2122. Damage assessment is currently in progress. Two fire brigade members were transported by ambulance to Tri-Point Medical Center with signs of heat exhaustion. Both individuals were verified to be free of contamination prior to transport.

"A news release will be made due to local media interest for this event. The NRC Resident Inspector has been notified."

* * * UPDATE FROM CHARLES ELBERFELD TO DONALD NORWOOD AT 1636 EDT ON 3/29/2010 * * *

"The purpose of this call is to update Event Number 45798. In the notification made on 3/28/10, it was stated that a news release would be made due to local media interest for this event. After further review, it was determined that discussions with the media adequately addressed the interest and that a new release will not be made. The NRC Resident Inspector has been notified."

SAFETY EQUIPMENT FAILURE - PROCESS GAS DETECTION SYSTEM FOUND INOPERABLE

"At 0808 CDT on 03-29-10, the Plant Shift Superintendent (PSS) was notified that C-333 Unit 5 Cell 6 Process Gas Detection System (PGLD) was found with the READY light not illuminated when Operations were performing the manual test firing required by TSR surveillance requirement SR 2.4.4.1-1. This PGLD System contains detectors that cover Unit 5 cell 6 cell housing and Section 3 of the cell bypass piping. At the time the READY light was discovered not illuminated, these areas were operating above atmospheric pressure. The PGLD System was declared inoperable, TSR LCO 2.4.4.1.A.1 and 2.4.4.1.C.1 were entered and a continuous smoke watch was put in place within one hour. The power supply module was replaced and the system was satisfactorily tested. The system was declared operable at 1030 CDT on 03-29-10.

"TSR 2.4.4.1 requires that at least the minimum number of detector heads in the cell housing and in each defined section of the cell bypass are operable during steady state operations above atmospheric pressure. With the Unit 5 Cell 6 PGLD system inoperable, none of the required cell housing heads were operable. A PGLD head was manually actuated ('smoke tested') and the system would not alarm. Engineering has determined that the system would not have been able to perform its intended safety function.

"This event is reportable as a 24 hour event in accordance with 10CFR76.120(c)(2)(i).

"The NRC Senior Resident Inspector has been notified of this event."
