LOSS OF COMMUNICATIONS CAPABILITY DUE TO A MAJOR CABLE CUT
"On 12/06/2011 at approximately 1306 CST, a major offsite underground communications line was severed, cutting telephone lines to Clinton Power Station. The lost communications include the Health Physics Network (HPN), Emergency Notification System (ENS) and the ability to send Emergency Response Data System (ERDS) data to the NRC. Alternate communications have been established with the NRC and other agencies.
This event is reportable due to the major loss of emergency assessment capability per 10CFR50.72 (b)(3)(xiii). The time to repair the lines and restore communications is unknown at this time.
The NRC Resident Inspector has been notified.
* * * UPDATE AT 1624 EST ON 12/6/11 FROM BOB RUSH TO S. SANDIN * * *
The communication lines have been repaired and HPN, ENS, and ERDS have been restored. Notified R3DO (Skokowski).

AGREEMENT STATE REPORT - POSSIBLE MEDICAL EVENT
The following was received from the State of Minnesota via email:
"Minnesota Department of Health (MDH) was initially notified on December 14, 2011, by a representative from the University of Minnesota about a possible HDR [High Dose Rate] medical event. As of December 15, 2011 MDH was notified of the determination of a medical event that resulted in a 50% overexposure to an unintended area."
* * * UPDATE FROM BRANDON JURAN TO DONALD NORWOOD AT 1149 EST ON 12/23/2011 VIA E-MAIL * * *
"This notification is to provide follow-up information to the medical event initially reported on 12/15/2011 by Lynn Dunbar of the Minnesota Department of Health.
"The patient was being treated for uterine cancer using iridium 192 high dose-rate (HDR) brachytherapy. The written directive called for treating the target area to approximately 600 cGy per fraction for five fractions. Instrumentation consisted of four plastic Heyman capsules, a tandem, and a pair of ovoids. Of the seven pathway options, five were identified to be used in the treatment plan for delivering the dose, and catheters were inserted into these instruments.
"The first fraction of five was delivered with the tandem catheter not fully inserted into the tandem. The second of five fractions was delivered according to the original written directive. The 3rd, 4th, 5th fractions were modified to give the treatment volume the originally intended total dose. The dose to the rectum would have been 157.5 cGy if all five fractions were completed according to the original written directive. The dose to the rectum as treated was 256.2 cGy, about 63% more than intended."
The Event Date provided in the initial report was changed (from 12/15/2011 to 12/6/2011) and the number given as the 'MDH #' (MDH #: 1049-206-27) was re-assigned as the licensee's license number based on information provided in the update.
Notified R3DO (Pelke) and FSME EO (Einberg).
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.

TECHNICAL SUPPORT CENTER NON-FUNCTIONAL DUE TO PLANNED MAINTENANCE
"Between December 6, 2011 and January 13, 2012, a sequence of activities are planned that will render the Technical Support Center (TSC) non-functional at times by removing the emergency ventilation system from service. These activities are being performed in support of planned preventive maintenance and extended power uprate facility upgrades. In preparation for these emergency ventilation system outages, the TSC emergency responders were notified that if an emergency occurred during these outages the Emergency Coordinator and the TSC staff involved with classification, notification and PARS should report to the control room. All other TSC personnel should report to the Operational Support Center. The duration for each of these TSC outages is expected to be less than 24 hours. The NRC Operations Center will be provided an update to this notification when the TSC emergency ventilation has been removed from service and following restoration for each time period. This 8 hour notification in accordance with 10 CFR 50.72(b)(3)(xiii)."

LOSS OF EMERGENCY ASSESSMENT CAPABILITY
"At 0900 hours EST, on December 6, 2011, Emergency Preparedness personnel determined that the Unusual Event and Alert EAL criteria for the Liquid Waste Disposal Effluent could not be achieved due to the monitor range capability. Specifically, the R-18 effluent monitor instrument range has a maximum range of 1.0E+06 with the alarm set at 1.0E+06. The UE and Alert criteria, which are 2 times the alarm and 200 times the alarm respectively, both exceed the instrument range.
"The NRC Resident Inspector has been notified."
This condition has existed for some time (at least three years) and was discovered during a review of the Operating Experience database involving a similar condition reported by Crystal River-3. The licensee maintains the ability to perform grab samples of the liquid effluent for assessment.
* * * UPDATE ON 12/08/11 AT 2330 EST FROM RAY BUZARD TO JOHN KNOKE * * *
As a follow-up to the condition reported above, the licensee inspected other discharge and effluent radiation monitors for similar conditions and provided the following update:
"At 2250 hours EST, on December 8, 2011, it was determined that the Alert EAL classification criteria for the Steam Generator Blowdown radiation monitors and the Condensate Polisher Sump discharge radiation monitor could not be achieved due to the monitors range capability. Specifically, the R-19 A, B, C and the R-37 monitors instrument range have a maximum range of 1.6E+06 which is less than the Alert EAL classification criteria. This information was validated as a follow-up to a similar event which was reported on December 6, 2011 in EN# 47501.
"The NRC Resident Inspector has been notified."
R2DO (Musser) notified.
