TEXAS AGREEMENT STATE REPORT - TWO TRITIUM EXIT SIGNS MISSING

The following information was received via e-mail from the State of Texas Radiation Branch:

"On June 15, 2010, the Agency received a letter from a company operating under a General License in the State of Texas. [While] conducting an inventory of tritium (H-3) exit signs used at their facilities, they found that two signs containing 10 curies each of H-3 were missing from a facility in Hewitt, Texas. The signs were manufactured by SRB Technologies, Inc., Model BetaLux-E. A search of the facility was conducted and interview with the individuals working at the facility were held. The interviews did not provide any information on the location or disposition of the signs. The company is removing all exit signs containing tritium and returning them to the manufacturer to prevent a reoccurrence of the event. Additional information has been requested by this Agency and will be provided when received."

TX Incident # I-8754

* * * UPDATE FROM TEXAS (TUCKER) TO HUFFMAN (VIA E-MAIL) AT 1515 EDT ON 6/15/10 * * *

"The company provided the following information [to the Texas Radiation Branch] during a phone conversation.

"The signs were found to be missing on May 20, 2010. The loss was reported to the Health and Safety Group (HSG) on May 25,2010. The HSG Group incorrectly interpreted the reporting criteria for this event and believed that it only required a 30 day written report. The HSG manager stated that they would change their procedure to insure any future required reports would be done on time."

R4DO (Powers) and FSME (McIntosh) notified.

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

PENNSYLVANIA AGREEMENT STATE REPORT - STUCK SOURCE

The following information was received from the Pennsylvania Bureau of Radiation Protection via facsimile:

"The licensee called the PaDEP Southwest Regional Office (SWRO) on the morning of June 14, 2010 to provide a 24-hour verbal notice of a stuck source. The licensee secured the location, and contacted the manufacturer and their consultant for instruction on how to proceed. Equipment appears to have failed to function as designed, thus, the licensee and DEP are doing a 24 hour report per 10CFR30.50(b)(2).

"On June 14, 2010, the SWRO of the Department received verbal notification of a stuck radioactive source. DEP was informed the threaded cap on the end of their cobalt-60 source became stuck within the mold they were checking. The licensee moved the unit to a secure location, roped-off this area, and began to conduct surveys. The manufacturer (Berthold Technologies), along with an outside consultant were contacted for support on recovering the source. We were told the activity of the source is 5.3 millicurie (mCi), but it is not clear if that is a decayed or initial activity. The source information from their license is as follows: Berthold Technologies, source model P2608-100, Co-60 sealed source capsule.

"DEP Central Office is awaiting further details from its Western Regional Office and the licensee's facility staff and consultant to confirm radiation survey measurements and source recovery. It is anticipated that Regional staff will conduct a follow-up inspection. Final even details will be communicated in a NMED report."

UNANALYZED CONDITION DUE TO CONTAINMENT SPRAY RECIRC SUMP ISOLATION VALVE FAILURE TO STROKE CLOSED

"At 0519 CDT on June 17th, Unit 2 was closing the 2CS009B, Containment Spray Recirc Sump Isolation Valve, as part of post maintenance testing when the valve stopped stroking (i.e. mid position). The 2CS009B valve was being stroked closed for restoration from a successful timed stroke in the open direction. The 2CS009B valve was manually closed and verified closed via limit switch indication.

"With the 2CS009B valve unable to be closed from the Main Control Room, an unanalyzed condition may have existed where, during a large break LOCA requiring cold leg recirc, the Refueling Water Storage Tank (RWST) had an additional flow path to the containment recirc sump. This potentially challenges the operators to complete the switchover prior to the RWST reaching 9%, the point at which pumps taking a suction from the RWST only are shutdown. This condition is still being evaluated."

The licensee notified the NRC Resident Inspector.

OFFSITE NOTIFICATION DUE TO INADVERTENT INITIATION OF EMERGENCY PREPAREDNESS SIRENS

"At 1045 [CDT] on 6/17/2010, the Monticello Nuclear Power Generating Plant (MNGP) received a report from the Sherburne County Sheriff Dispatcher that there had been an inadvertent manual initiation of Emergency Preparedness sirens in the county while performing siren testing in preparation for inclement weather anticipated later this evening. All plant conditions/parameters are normal. A total of 48 emergency sirens were on for approximately 1 minute before being secured. The inadvertent initiation of the sirens was determined to be reportable under 10 CFR 50.72(b)(2)(xi), 'News Release or Notification of Other Government Agency.'

"Sherburne County, the State of Minnesota, and the site NRC Resident Inspector have been notified."

OFFSITE NOTIFICATION DUE TO GRASS FIRE OUTSIDE PROTECTED AREA

"At 1400 EDT on 6/17/2010, a grass fire was reported by security officers at the main entrance facility. The fire was located outside of the protected area and outside the main entrance to the plant. The cause of the fire appears to be sparks from an 18 wheel truck's wheel contacting a curb. These sparks apparently ignited dry grass in the surrounding area. The site fire response team responded to the incident and discovered approximately a 20' x 20' area of grass burning. Extinguishing agent was applied by on site personnel and the fire was extinguished. Off site assistance (Saint Leonard Volunteer Fire Department) reported to the scene and provided makeup water to the site fire engine. There was no damage to any equipment or structures. A courtesy notification was made to Calvert Control Center at 1445 to ensure local agencies were informed of the call for assistance to the local fire department."

The licensee notified the NRC Resident Inspector.
