The following information was obtained from the State of Ohio via email:
"The shutter locking mechanism for the licensee's Rock Belt fixed gauge has failed. The shutter is still functional, but is not capable of being locked. This failure was identified by the manufacturer's service technician during a site visit on 5/6/2010 while they were troubleshooting the electronics unit for this particular fixed gauge.
"The gauge was manufactured by Ohmart/VEGA, Model SH-100, Serial # M-5800, containing a 50 mCi Cs-137 source installed in June 1991. This style of source holder is currently no longer being manufactured and the licensee is working with Ohmart/VEGA to determine possible repair or replacement options."

"On June 1, 2010, at 0900 hours CDT, Clinton Power Station removed the Technical Support Center (TSC) ventilation system from operation to facilitate preventive maintenance to replace charcoal media in the ventilation system filter assembly.
"This work is expected to last approximately 3 days, during which the TSC ventilation system will be unavailable. If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable due to ambient temperature, radiological, or other conditions. If relocation of the TSC becomes necessary, the Station Emergency Director will relocate the TSC staff to an alternate TSC location in accordance with applicable site procedures giving first consideration to the Control Room. TSC facility leads have been made aware of this contingency.
"This notification is being made in accordance with 10CFR50.72 (b) (3) (xiii) due to the potential loss of an emergency response facility (ERF) because of the unavailability of the emergency filtration mode of the ventilation system. An update will be provided once the TSC ventilation has been restored to normal operation. The NRC Resident Inspector has been notified."

| This material event contains a "Category 3" level of radioactive material. | Event Text POTENTIALLY LOST SOURCE
On the afternoon of May 28, 2010, Nucletron Corporation (Columbia, Maryland) received a call from 21st Oncology Katin Radiation (Martinsburg, West Virginia) who received a phone call from QSA Global (Burlington, Massachusetts) saying they received a call from a GM plant located in the Martinsburg, West Virginia general area. The GM plant had mistakenly received a properly shielded radiation source from a common carrier. Because of an exception in the shipping paperwork, the shielded source was supposed to be shipped back to Katin Radiation.
The device is a Microselectron HDR Brachytherapy Afterloader: serial number #31836. The source is IR-192, 4.69 Ci, serial number D36C-1703.
The common carrier is investigating the driver's routing and logistics during the day of the event in order to track the source.
* * * UPDATE FROM DEBRA BENSEN TO VINCE KLCO ON 6/1/10 AT 1759 EDT * * *
Notified by the licensee that the source was located at a GM plant in the Martinsburg, West Virginia area. The common carrier picked up the source and delivered it to Katin Radiation at 1632 EDT. The source packaging was inspected and showed no evidence of damage or tampering.
Notified the R1DO (Dentel), FSME (Camper), and ILTAB (English).
THIS MATERIAL EVENT CONTAINS A "CATEGORY 3" LEVEL OF RADIOACTIVE MATERIAL
Category 3 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 some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial gauges involving high activity sources (for example: level gauges, dredger gauges, conveyor gauges and spinning pipe gauges) and well logging. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
Although IAEA categorization of this event is typically based on device type, the staff has been made aware of the actual activity of the source, and after calculation determines that it is a Category 3 event.
Note: the value assigned by device type "Category 2" is different than the calculated value "Category 3" |

"The following event description is based on information currently available. If through subsequent reviews of this event, additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS or under the reporting requirements of 10CFR50.73.
"On June 01, 2010, at approximately 0715 Mountain Standard Time (MST), the Palo Verde Emergency Planning Department discovered that public warning system siren No. 17 was not responding, and therefore, is out of service. The loss of siren No. 17 could potentially impact a population of approximately 1196 people in the 5-mile Emergency Planning Zone (EPZ).
"Since the loss of siren No. 17 could impair Arizona Public Service Company's ability to inform greater than 5% of the population within the EPZ, this notification is being made in accordance with 10 CFR 10.72(b)(3)(xiii). If an event occurs while siren No. 17 is out of service, the Palo Verde Emergency Plan has a contingency for dispatching Maricopa County Sheriff's Office (MCSO) vehicles with loud speakers to alert persons within the affected area. The MCSO is prepared to implement this contingency should it become necessary.
"The NRC Resident Inspector has been notified of siren No. 17 being out of service and this ENS call."
* * * UPDATE FROM DAVE OAKES TO HOWIE CROUCH @ 1818 EDT ON 6/01/10 * * *
"Siren number 17 was returned to service at 1435 MST. The NRC Senior Resident Inspector has been notified."
The remote radio was replaced and all post-maintenance testing was completed.

"On May 27, 2010, during a control board walkdown, it was discovered that two sets of auxiliary building tunnel exhaust dampers were open at the same time. This configuration created a pathway from the secondary containment to the outside. The condition was immediately corrected. Additional investigation determined that this condition existed since May 11, 2010, when Millstone 3 was in Mode 5.
"Technical Specification 3.6.6.2 'Secondary Containment' is applicable in Modes 1, 2, 3, and 4. The condition discovered on May 27, 2010, rendered Secondary Containment inoperable. Further evaluation since the discovery date concludes that the secondary containment structure was in a condition which could prevent the fulfillment of the safety function for controlling the release of radioactive material. [On June 1, at 1550 EDT the licensee determined that the event was potentially reportable].
"An investigation is on-going.
"This condition is being reported pursuant to 10 CFR 50.72(b)(3)(v)(c).
"The NRC Senior Resident Inspector has been notified [by the licensee]."
The State of Connecticut and the Town of Waterford were notified. A press release will be issued. |

"At 1239 CDT on June 1, 2010, Byron Station Technical Support Center (TSC) ventilation (OW25C), filtration system was identified as nonfunctional. This failure affects the ability of the TSC ventilation to maintain adequate radiological habitability in the event of an emergency with an airborne radiological release. All other capabilities of the TSC are unaffected by this emergent condition. Currently, troubleshooting/investigation is being performed. This condition is considered a major loss of emergency assessment capability and is reportable under 10CFR50.72(b)(3)(xiii).
