DISCOVERY OF AFTER-THE- FACT EMERGENCY CONDITION - UNUSUAL EVENT DUE TO RCS LINEUP
"On 5/4/2010 at 15:12 CDT when attempting to flush CH-1A charging pump, a loss of charging flow occurred.
CH-193 discharge valve for CH-1A charging pump was found to be open. This resulted in a flow path to the auxiliary building sump tank when CH-356 charging pump CH-1A discharge drain valve to waste disposal system was opened. This resulted in an approximately 38 gpm leak from the reactor coolant system via letdown to waste. This leak was isolated within 1 minute."
The site entered and exited the conditions for NOUE before the shift manager was able to make an E-plan call. There are currently no emergency conditions on site and an NOUE was never declared. The reactor continued to operate at 100% power throughout the event. The cause of this event is believed to be a valve line-up error.
The NRC Resident Inspector has been notified. The site plans to notify the State of Nebraska. No other notifications are planned.
* * * RETRACTION AT 1625 EDT ON 5/5/10 FROM MATZKE TO HUFFMAN * * *
"The declaration of Unusual Event SU 5 EAL 2, RCS leakage, on 5/4/10 is being retracted, because the declaration was inaccurate. The leak was an intersystem leak of the CVCS, not RCS leakage, and the leak was isolated as previously noted. Therefore, the leakage did not meet the initiating condition for the EAL."
The licensee has notified the NRC Resident Inspector and plans to notify the State of Nebraska. Notified R4DO (Farnholtz), NRR EO (Quay), and IRD (McDermott).

AGREEMENT STATE REPORT - MEDICAL MISADMINISTRATION
A patient was treated in early May with a vaginal applicator using three doses of High Dose Rate (HDR) brachytherapy. On May 11, 2010, the patient contacted the doctor's office and complained of skin irritation to her leg. On May 18, 2010, the patient again called to report continued skin irritation. On both of these dates, the patient could not come in to see the doctor. On May 26, 2010, the patient was seen by the doctor and radiation irritation was evident on her leg. Initial estimates of the leg dose are greater than 50 REM. Both the patient and doctor have been notified of this event.
The source was Yttrium (unknown strength). [See correction below]
The State is investigating this event.
* * * UPDATE FROM CARL SULLIVAN TO PETE SNYDER ON 6/10/10 AT 1156 EDT * * *
The event date in the header was corrected to 5/4/10. The source was Ir-192 with an activity of 3506.34 mCi on 5/4/10.
The State continues to investigate this event.
Notified R4DO (Shannon) and FSME (Villamar).
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
