AGREEMENT STATE REPORT - DAMAGED X-RAY FLOURESCENCE DEVICE

The following information was obtained from the State of Nebraska via facsimile:

"The Douglas County Health Department, a Nebraska licensee (license no. 01-45-01), reported that a Radiation Monitoring Devices, Inc. (RMD) Model LPA-1 portable x-ray fluorescence [XRF] device had been damaged on May 27, 2009. The XRF contained 12 millicuries of Cobalt-57. An authorized user left the XRF on a window sill and the XRF fell approximately eight feet to the floor. The XRF case was cracked in several pieces, but the integrity of the sealed source shield was not damaged. Radiation dose readings of the damaged XRF were within the expected range [for this device]. No individuals of the public or occupational workers were exposed as a result of this event. The licensee was able to return the XRF to its shipping container [which was placed in the] licensee's secured storage facility. The licensee was instructed to contact the manufacturer, perform a leak test and contact [the State of Nebraska] prior to shipping the XRF back to the manufacturer."

CALIFORNIA AGREEMENT STATE REPORT - STOLEN TRITIUM EXIT SIGN

The following information was obtained from the licensee via email:

"[The licensee] notified the [California Radiation Health Bureau] that a tritium exit sign had been stolen from a Roseville property they manage. The sign was an SRB Technologies Model 171-10-wh-s-gn."

SRB Technologies Tritium exit signs typically contain 10-20 Ci of tritium.

California Incident number: 5010-052809

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.

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

BOTH TRAINS OF AUXILIARY BUILDING GAS TREATMENT SYSTEM RENDERED INOPERABLE

"On May 27, 2009, Plant Operations was shutting down the Auxiliary Building General Ventilation system [ABGTS] as a compensatory measure in response to an historical deficiency that was identified in the surveillance procedure for conducting TS SR 3.7.12.4. The building's general ventilation was being shut down to place the plant in a known tested configuration to ensure continued safe operation while plans were being developed to properly perform SR 3.7.12.4. While shutting down the building's ventilation system, the operator shut down the building's supply fans followed by the shut down of building's exhaust fans. This sequence resulted in an unacceptable differential pressure condition across a set of Auxiliary Building Secondary Containment Enclosure (ABSCE) doors. Upon identification of the failed doors at 1905 EDT on May 27, the plant entered TS Condition 3.7.12.B for 2 trains of ABGTS being inoperable. Repairs to re-establish the integrity of the ABSCE were immediately initiated and TS Condition 3.7.12.B was exited at 2239 EDT, approximately 3 and 1/2 hours later.

"The reportability of this condition was not recognized at the time of this event. Based upon a review subsequent to the event on June 1, 2009, this event was determined to be reportable under 10 CFR 50.72(b)(3)(v)(C) and (D) as a condition that could have prevented the safety function of structures or systems that are needed to: (C) Control the release of radioactive material; or (D) Mitigate the consequences of an accident.

"The licensee has notified the NRC Resident Inspector."

LOSS OF TSC AIR CONDITIONING UNIT COMPRESSOR

"On 5/20/09, the Technical Support Center (TSC) air conditioning unit compressor failed to restart following refueling outage electrical bus maintenance. On 5/31/09, the compressor was discovered to be shorted to ground. The short renders the air conditioning unit nonfunctional and at 1650 on 6/1/09 the nonfunctional air conditioner was determined to adversely affect TSC habitability based on meteorological conditions. TSC filtration capabilities are not affected by this problem. The nonfunctional air conditioner leaves the TSC in a degraded state; however, the TSC is currently habitable and available for service. Should the TSC need to be activated, habitability of the TSC will be monitored per existing plant procedures. Relocation of the TSC to an alternate location would be performed in accordance with station procedures as necessary to ensure continued TSC functionality. The control room and all other emergency response facilities are unaffected by the TSC chiller outage. Work instructions to repair the chiller are in review and work is expected to commence on June 2nd and proceed with high priority. A follow-up notification will be made when the TSC chiller has been restored. This event is being reported as a loss of emergency preparedness capabilities in accordance with 10 CFR 50.72(b)(3)(xiii). The NRC resident has been notified."

UNUSUAL EVENT - SMOKE ALARM IN PROTECTED AREA LASTING GREATER THAN 15 MINUTES

Licensee declared an Unusual Event due to a possible fire in the protected area inside containment. The smoke alarm could not be verified before 15 minutes, therefore licensee entered into EAL HU 2.1. There are 17 smoke detectors located inside the containment, and it is unknown if more than one smoke detector initiated the alarm. The local fire department was not requested to respond to the site. Licensee is sending personnel inside containment to investigate weather or not this alarm was spurious. There is no indication of smoke or an increase in temperature in or around the containment. There was no radiological release to the environment.
