ENTRY INTO TECHNICAL SPECIFICATION REQUIRED SHUTDOWN
"While operating in mode 1 at 100% power, [the licensee] identified [a] failure to comply with Technical Requirements [TR] Manual 3.7.20, Snubbers, Condition C. [The] required action C.1 requires the performance of an inspection of required snubbers affected by transient in accordance with Table TR 3.7.20-1 within 6 months of the event. WCNOC [Wolf Creek Nuclear Operating Corporation] determined that a portion of the required inspections was not completed for transients that occurred during Refueling Outage 16 (Spring 2008). TR 3.7.20, Snubbers, Condition D requires affected systems to be declared inoperable immediately. No major equipment was out of service prior to the event.
"At 1525 CST, TS [Technical Specification] LCO [Limiting Condition of Operation] 3.7.8, Essential Service Water (ESW) System, was declared not met, [and therefore], both trains of ESW [were declared] inoperable. With both trains of ESW inoperable, TS LCO 3.0.3 was entered and preparations for unit shutdown commenced. Additionally, with both trains of ESW inoperable both Emergency Diesel Generators were declared inoperable. TS LCO 3.8.1, AC Sources - Operating, Conditions B and F were entered.
"Actions to complete required inspections per TR 3.7.20 Table TR 3.7.20-1 have been initiated.
"Shutdown was commenced at 1618 CST.
"NRC Senior Resident was notified 1/26/2010 15:30 CST regarding entry into TS LCO 3.0.3."
* * * UPDATE FROM RICK HUBBARD TO JOHN KNOKE AT 2206 EST ON 1/26/10 * * *
The licensee completed inspection of Train "B" snubbers, and at 2013 CST, the licensee exited TS LCO 3.0.3 based on restoration of Train "B" of Essential Service Water System to operable status. Licensee is still inspecting Train "A" snubbers.
The licensee has notified the NRC Resident Inspector. Notified R4DO (Greg Pick)

AGREEMENT STATE REPORT - POTENTIAL SHALLOW DOSE EQUIVALENT OVEREXPOSURE
"On 1/26/10, the Agency [State of Texas] received a report from the licensee's Radiation Safety Officer stating they had received a report from their dosimetry processor indicating one of their workers had received 230 rem to the badge worn on his left hand. The right hand badge read 1.420 rem for the same period. The RSO stated that the individual involved handled predominantly Fluorine (F)-18. His deep dose equivalent (DDE) for the same period was 439 millirem. The RSO stated that the typical exposure to the hands is between 500 and 1,200 millirem and that the DDE was about 250 millirem per exposure period. The RSO believed the exposure was to his badge only. The RSO stated that on December 23, 2009, the individual was involved in a spill of F-18 and his badge may have become contaminated causing the exposure. The RSO stated that he was waiting on a statement from the individual involved.
"On February 25, 2010, the Agency received a written report of the event from the licensee. A review of the report indicated that the information provided did not appear to substantiate the conclusion made by the licensee that this was a badge only event. The Agency's position is that the actual shallow dose equivalent (SDE) is currently unknown, and may have exceeded the limit. The Agency has begun their investigation. Additional information will be provided as obtained."
Texas Incident Number I-8707
* * * RETRACTION FROM ART TUCKER (VIA EMAIL) TO HOWIE CROUCH @ 0944 EDT ON 3/26/10 * * *
"It was determined that the individual was involved in a spill of F-18 and his badge became contaminated causing the exposure. It is believed that the worker contaminated his badge when he removed his gloves after cleaning up the spill. Surveys of the room after the spill indicated that the door handle used to exit the room by the individual was contaminated. The individual performed a contamination survey of his hands after leaving the room and they were not contaminated. Calculations indicate that, based on the specific activity of the F-18 involved, a small fraction of a milliliter would be required to cause this dose to the badge. The Agency agrees that this was a badge only exposure.
"This Agency is requesting that this event be retracted."
Notified R4DO (Deese) and FSME EO (McIntosh).
