| Event Text AGREEMENT STATE - BRACHYTHERAPY TREATMENT DOSE DELIVERED DIFFERS FROM PRESCRIBED
The following was received via fax from the state of Wisconsin:
"On July 8, 2010, the licensee's Radiation Safety Officer (RSO) reported the preliminary identification of six medical events involving permanent implants of I-125 for prostate brachytherapy where the total dose delivered differs from the prescribed dose by 20% or more. During recent routine inspection, DHS [Department of Health Services] inspectors determined that the licensee was not reviewing prostate brachytherapy cases against the medical event criteria. The licensee is currently evaluating all 269 prostate implants performed since August 2003. This review is ongoing and will include an assessment of whether any implants involved doses to an organ or tissue above 0.50 Sv and 50% more than the expected dose. The licensee is in the process of notifying the affected patients and referring physicians.
"The reported medical events involve two locations of use. One facility identified three under doses (74.8%, 75.2%, and 76.5%) and one overdose (121.4%). The second facility identified one under dose (78.2%) and one overdose (121.0%). DHS inspectors are investigating these medical events and will send a special inspection team following completion of the licensee's review"

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. |

| Event Text ELECTRICAL FAULT DISABLED PUBLIC ADDRESS SYSTEM WHICH SUPPORTS VARIOUS ALARM ANNUNCIATORS
"At approximately 1200 hours (EST) on 7/12/2010, an electrical fault was identified in the fire alarm system. This fault disabled the public address portion of the system which supports annunciation of plant alarms including the following: fire alarm, criticality alarm, take-cover alarm, [carbon dioxide] discharge alarms. Trouble shooting of the problem is continuing. There is no impact to actual detection, suppression, etc. systems. Compensatory measures include the following: stop SNM handling and movement, fire patrols, restriction of hot work, notification to facility personnel, evacuation of nonessential personnel from production areas, fire brigade on standby and radios provided to fire brigade officers and some fire brigade members.
"It is believed that the condition was associated with heavy rainfall and possible water intrusion.
"There were no actual safety consequences to workers, the public, or the environment associated with the event. Potential consequences to workers, the public, or the environment are mitigated by compensatory measures."
The licensee notified the NRC Resident Inspector.
* * * UPDATE FROM RANDY SHACKELFORD TO JOHN KNOKE AT 1628 ON 7/15/10 * * *
"The public address portion of the plant alarm system was restored on 7/13/2010. It appears that recent rain storms caused some wiring to develop short circuits. These short circuits were corrected. The system is continuing to be monitored and wiring may be identified that requires replacement. It was confirmed that the criticality alarm portion of the plant alarm system was not impacted during the recent outage."

"At 1834 hours on 7/14/10, the Unit 1 'C' Reactor Coolant Loop was declared inoperable due to small unisolable leaks on the 'C' Steam Generator secondary side surface sample line. Two small through-wall flaws were identified in the piping upstream of 1 -SS-217, 'C' Steam Generator surface sample line manual isolation valve. The piping is Class 2 and the non-conforming condition could not be evaluated with the steam generator pressurized. Based on the condition of the piping and the inability to evaluate the flaw, the 'C' Steam Generator was declared inoperable per Technical Requirements Manual 3.4.6, ASME Code Class 1, 2 and 3 Components. Subsequently, Technical Specification 3.4.4 was entered to place Unit 1 in Mode 3 within 6 hours.
"At 1934 hours on 7/14/10, North Anna Unit 1 initiated a shutdown in accordance with Technical Specification 3.4.4. The unit will be shutdown and the line will be evaluated and repaired."
The licensee is presently at 82% power and coasting down in power. All safety systems are fully operable.
The licensee has notified the NRC Resident Inspector.
* * * UPDATE FROM PAUL TRENT TO DONALD NORWOOD AT 0015 HRS ON 7/15/2010 * * *
North Anna Unit 1 entered mode 3 at 2353 hrs. There were no complications during shutdown. One source range monitor failed downscale low. The other source range monitor is operating correctly. The failure of this source range monitor did not affect shutdown capabilities.

"On July 2, 2010, Southern Nuclear Operating Company (SNC) provided a non-emergency event notification (EN# 46067) for an apparent non-compliance with 10 CFR 26.61 relating to self-disclosure requirements. During implementation of corrective actions for that event, Shaw Nuclear Services Inc. (Primary Construction Contractor for Vogtle 3&4) personnel identified that several of the self-disclosure forms received from a sub-contractor had very similar handwriting. An incident investigation was initiated to ascertain the relevant facts. During that investigation, Shaw identified two supervisory personnel from the sub-contractor organization who apparently provided the suspect self-disclosure documents for other employees from their company. Unescorted access for the two supervisory personnel was suspended and they were removed from the site pending completion of the investigation. All suspect self-disclosure forms were removed from the files, and the affected individuals have completed and submitted new self-disclosure forms. No other evidence of policy violations has been identified during this process. The investigation into the FFD event continues. On July 14, 2010, Shaw notified SNC that sufficient indication exists that the actions of the sub-contractor supervisory personnel may have violated the Shaw FFD policy. As such, this issue is reportable in accordance with 10 CFR 26.719(b)(2)(ii), which requires a non-emergency event notification."

| Event Text DAMAGED MOISTURE DENSITY GAUGE
The licensee was using a MC3 moisture density gauge (s/n M38098467) at a construction site in Kauai, HI. During the construction of the Kamualaii road a water truck drove over the gauge and damaged the casing. The source was able to be returned to the shielded position. Licensee is contacting the manufacturer for transporting the MC3 gauge back to them for repair. The radionuclides used with the gauge are 50 mCi of Am-241/Be and 10 mCi of Cs-137. Licensee said they would perform a test for any source leakage. | |
