AGREEMENT STATE - DAMAGE TO TROXLER MOISTURE DENSITY GAUGE

The Washington State Department of Health, Office of Radiation Protection provided the following report via e-mail:

"The Licensee was working with a Troxler Model 3430, portable moisture density gauge, serial number 19739, having a 10 millicurie, Cesium-137 and a 40 millicurie, Americium-241/Beryllium sealed sources. The work was being done at a temporary job-site near Walla Walla, Washington. The gauge operator was taking measurements with the Cs-137 source rod inserted into the test hole. The operator walked away from the gauge to look for the next test site. While the operator was away, the gauge was struck by a front-end loader. The gauge operator cordoned off the area and contacted the Radiation Safety Officer. The RSO then contacted the Office of Radiation Protection (ORP) to make a verbal report. Two ORP staff were already in the vicinity and were rerouted to the incident scene. When staff arrived they reported the gauge had been visibly damaged. The plastic exterior was smashed with the source rod still in the test hole. The gauge's guide rod with the handle had been sheared-off by the front-end loader. ORP staff were able to push the source rod back into the gauge's shielded position. They also took a wipe sample from the source rod, the gauge exterior, and surveyed the soil where the source rod had been. No contamination was found. The gauge was placed back into its transport box. ORP staff took dose-rate readings on the outside of the box and found normal levels. The gauge was taken to the licensee's storage facility in Walla Walla where it awaits shipping instructions for returning it to Troxler.

"The Licensee is being cited by DOH for not keeping the gauge under constant surveillance and control while away from an approved storage location."

Washington Report WA-08-040

TSC HVAC SYSTEM RENDERED NONFUNCTIONAL

"Work Order Number 1050889203 will perform maintenance on 1R24-S026 - 600/208V MCC. The specific work is to remove the LA 600 Breakers in frames 1C & 5C to take measurements for replacement breakers. The removal and measurement of the two breakers will be performed by two work crews simultaneously to minimize out of service time. In order to perform this work activity, the power will be removed from 1R24-S026 which also supplies power to the TSC HVAC rendering it nonfunctional during the performance of this work activity. This work activity is planned to be performed and completed within a 12 hour work shift with 2 hours scheduled for establishing and removing the clearances for a total of 14 hours. During the time this activity is being performed, the TSC air handling unit, TSC condensing unit, TSC filter train, and the fan unit for the TSC filter train will not be available for operation. As such, the TSC HVAC will be rendered nonfunctional during the performance of this work activity.

"If an emergency declaration is made requiring activation of the TSC during the time this work activity is being performed it will take approximately (3-6) hours to return the equipment back to an operable status dependent on the stage of the work activity at the time the emergency occurs. Plans are to utilize the TSC for any declared emergency during the time these work activities are being performed, as long as radiological conditions allow. Procedure 73EP-EIP-063-0, Technical Support Center Activation, provides instructions to direct TSC management to relocate to the Control Room and TSC support personnel to relocate to the Simulator Building to continue TSC activities if it is necessary to relocate from the primary TSC."

Licensee notified NRC Resident Inspector.

At 1500EDT the MCC was re-energized and the HVAC equipment confirmed operable at 1518EDT on 06/17/08.

The licensee will inform the NRC Resident Inspector. Notified R2DO (Bonser).
