"At 2045 [CDT] on 8/14/12, MNGP [Monticello Nuclear Generating Plant] Operations determined that valves RHR-82 and RHR-84 had been inappropriately closed as part of an isolation clearance order for work on shutdown cooling suction piping. These valves are required to be open to provide overpressure protection for RHR piping passing through primary containment penetration X-12. Upon discovery of the condition, Primary Containment was declared Inoperable and the Required Actions of Tech Spec 3.6.1.1 were entered. Following discovery, the isolation was restored and the valves opened. At 0001 [CDT] on 8/15/12, Primary Containment was declared Operable.
"This issue is being reported in accordance with 10CFR50.72(b)(3)(v)(C) and 10CFR50.72(b)(3)(v)(D) as a condition that at the time of discovery could have prevented the fulfillment of the safety functions of a system needed to control the release of radioactive material or to mitigate the consequences of an accident.
"The MNGP Senior NRC Resident Inspector has been notified of this issue."
The licensee will contact the Minnesota State Duty Officer.
* * * RETRACTION FROM RANDY SAND TO CHARLES TEAL ON 08/23/12 AT 1545 EDT * * *
"This notification is a retraction of ENS 48190 based on further engineering evaluation. Monticello had previously evaluated penetration X-12 for thermally induced over pressurization. The evaluation qualified the piping components in the penetration for a maximum pressure of 3,306 psig using ASME Section III Appendix F operability criteria. The peak pressure calculated for the penetration was 2,743 psig based on Reactor pressure of 1000 psig with Reactor in Mode 1, and at worse case LOCA conditions for the Drywell. These assumptions and parameters envelop those that were present when valves RHR-82 and RHR-84 were closed on August 14, 2012. Therefore, this event would not have prevented the fulfillment of the safety function reported.
"The NRC Resident Inspector has been notified."

The following information was received by email:
"On August 15, 2012, the licensee notified the Agency [Texas Department of State Health Services] that sometime during the evening, a QSA Global 880D radiography camera was stolen out of the dark room of one of their trucks. The camera contained Iridium-192. The truck was parked at the licensee's office, however the Radiographer left the camera in the truck instead of transferring the camera to the vault. The thieves broke into five radiography trucks taking various items including generators and the one camera. A police report was filed with the Chamber County Sheriff's Department. The thieves did not take the crank outs or source tube."
"The State of Texas event number for this event is I- 8979. Additional information will be provided in accordance with SA 300."
Notified DHS, FEMA, USDA, HHS, DOE, DHS NICC and EPA EOC.
* * * UPDATE ON 8/15/12 AT 1330 EDT FROM CHRIS MOORE TO DONG PARK * * *
"On August 15, 2012, around 1130 [CDT], the licensee and Local Law Enforcement recovered the stolen QSA Global 880D Radiography Camera. The camera is stored in the vault at the licensee facility and is in normal working condition. [A person of interest has been identified]. The truck used by the thief was identified on video surveillance tape. The camera was in the back of truck at the residence of the thief. Investigation will continue for the company and radiographers [concerning] Increased Controls (IC) security violations."

THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL
Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

* * * UPDATE FROM DANLEY TO KLCO ON 8/16/2012 AT 0956 EDT * * *
The following information was received by email from the licensee:
The licensee received a call from the permit RSO [Radiation Safety Officer] that the Am-241 source has been recovered. It was located in the traffic management office.
Notified the R1DO(Powell), R4DO(Hagar) and FSME via email.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |

A HDR (High Dose Rate) treatment was planned for a patient's mammary area, but the delivery of the source position was offset from the intended delivery. The patient and referring physician were informed of the difference between the planned and the delivered dosage. The patient will receive follow-up to discuss potential options.

The following report was received via fax.
"Received report from the RSO on 2 Aug 2012 at approximately 1430 [EDT] hrs of a medical event that occurred on 1 Aug 2012. Two patients with similar procedures (mammosite) were being treated with an HDR [High Dose Rate]. First patient correctly treated, second patient treated with the same plan as the first. Second patient only under dosed by 0.5%. Their treatment plans were allegedly the same.
"Orlando office investigated licensee and found violation to be caused by operator error. Corrective action consists of a 'Time Out' to verify patient's name, plan, and treatment settings. Further action referred to the Office of Licensing and Materials, this office will take no further action on this incident."

PART 21 GROUP (Emai)
| Event Text PART 21 - STRESS CORROSION CRACKING CAUSING RELAY FAILURE IN SAFETY RELATED SYSTEMS
The following is summary of the information received from the licensee:
"The basic component is an Eaton-Cutler Hammer Type ARD660UR DC relay that is commercially dedicated by Westinghouse for use in safety related systems at Palo Verde Units 1, 2 and 3. Except for the Palo Verde plants, Westinghouse is not aware of any other plant that uses this relay as a safety-related component in normally energized applications.
"The relay contacts failed to change state when required to do so during postulated events and/or surveillance testing. Westinghouse has identified the kick-out spring as a possible contributing factor for the relay failure due to stress corrosion cracking. Other anomalies such as relay core barrel tolerance and potential material deficiencies are currently under review. Based upon testing at APS, the relay failure rate is low and non-reproducible. This indicates that a combination of factors could be resulting in the failures with different causes for each failure. Results of testing do not identify a common cause for the failures. For ARD660UR relays used in normally de-energized applications, the kick-out spring will be compressed for only a short period of time and exposure to additional heat generated by intermittent coil energization will be minimal. For relays in normally de-energized applications, it is not expected that the force provided by the kick-out spring will decrease significantly over time and the contacts will change position when the relay coil is de-energized. Westinghouse has not received any reports to date of relay contacts failing to properly change position when the relay goes from a de-energized to an energized state. Because of the kick-out spring's limited exposure to compression and heat generated by the relay coil, it is expected that the springs will perform as intended in normally de-energized applications for the qualified life of the relay.
