AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE
The following information was received via facsimile:
This event occurred at a construction job site in Northern Kentucky on the Westbound I-275 to Southbound KY-17 ramp, 30 feet up the ramp and approximately six feet from the outside edge of the roadway.
A pickup truck backed over a Humboldt moisture density gauge (model 5001, S/N 3182, 11 mCi Cs-137, 44 mCi Am-241:Be) while the gauge was in "backscatter mode." The operator had stepped away as instructed during the backscatter reading. The operator could not stop the pickup driver. The insertion handle on the gauge broke. The gauge shutter could not be closed. There was no apparent contamination of the site per a survey. Readings around the gauge were near background except the beam from the non-closable shutter. The licensee placed the gauge on the ground in a storage building with the beam pointed into the earth. A survey was conducted around the broken gauge and the site was secured. A check was made for contamination at the job site, on the transport truck, and in the storage area. The gauge was transported on June 9, 2011 to the normal secure storage site at the DOT secure storage shed in Frankfort, KY.
On June 10, 2011 the Kentucky Radiation Health Branch (KRHB) surveyed the gauge and inspected the site. KRHB advised the licensee that the device should not be disturbed until trained and licensed persons could package and ship the gauge. KRHP advised the licensee to secure the dosimetry of persons involved. KRHB will review, inspect and consider enforcement actions after the damaged device is secure.
Dosimetry was not available at the time of this report, but it will be obtained for affected individuals.

NOTIFICATION OF UNUSUAL EVENT DUE TO FLOODING THAT POTENTIALLY AFFECTED SAFETY RELATED EQUIPMENT
"Flushing activities were in progress on the 2A Auxiliary Feedwater (AF) Pump suction line from the Essential Service Water System (SX). At 1011 [CDT], during this flushing activity, the flushing hose ruptured and caused flooding in the Auxiliary Building that had the potential to affect safety related equipment needed for the current operating mode. This was due to the flood waters contacting the motors of the 1A and 2A AF Pumps.
"At 1026, an Unusual Event was declared by the Shift Emergency Director because the conditions for EAL entry were met for EAL HU5. Specifically the EAL conditions were 'Flooding in the Auxiliary Building that has the potential to affect safety related equipment needed for the current operating mode.' Auxiliary Feedwater is required to be operable in Mode 1 for each unit.
"The leak was immediately isolated (within 45 seconds of hose rupture) and remains isolated. Maintenance personnel are in the process of testing the 1A and 2A AF Pump motor to determine operability. The appropriate Tech Spec Action Statements have been entered on each Unit for the AF Pumps. The leak also caused the wetting of MCC [Motor Control Center] 132X1, which feeds the 1B AF Pump control power. The Unit 0 [Common] Component Cooling Pump feed breaker cubicle was also wetted. Investigation into these components are also in progress."
The licensee has entered Technical Specification LCO 3.7.5 Condition A which requires restoration of the one of the AF pumps within 72 hrs. There were no personnel injuries. The licensee has notified the NRC Resident Inspector.
* * * UPDATE FROM SCOTT BUTLER TO HOWIE CROUCH AT 1227 EDT ON 6/8/11 * * *
At 1122 [CDT] on 6/8/11, the Unusual Event was terminated due to the flooding conditions no longer existing. Evaluation of wetted components are still in progress.
The NRC Resident Inspector has been notified of event. Notified IRD (Gott), R3DO (Lara), NRR EO (Thorp), FEMA (Blankenship), and DHS (Flinter).

SECONDARY CONTAINMENT INOPERABLE DUE TO VENTILATION ALIGNMENT ISSUE
"Secondary containment was declared inoperable after transferring refuel floor supply fans. Secondary containment D/P [Differential Pressure] lowered to 0.17 inches of water vacuum which does not meet the surveillance requirement to have secondary containment vacuum greater than or equal to 0.25 inches of water vacuum. Refuel floor ventilation was restored back to the previous configuration and secondary containment D/P was restored back to greater than 0.25 inches of water vacuum. Vacuum was less than 0.25 inches of water for approximately 4 minutes.
"There were no actual radiological releases associated with the event.
"Actual secondary containment integrity was not challenged. The lowered secondary containment D/P was a result of a ventilation lineup change."
The licensee has notified the NRC Resident Inspector and the State of Minnesota.

AGREEMENT STATE - SHUTTER SEPARATED FROM GAUGE
The following was received via fax:
While removing the gauge the shutter became partially separated from the body. The source did not leave the gauge. The operator placed the gauge face down on the shutter assembly in a lead lined transport box. The gauge was surveyed and the max radiation field was 0.026 mR/hr. There was no exposure to personnel. The area was cordoned off and the manufacturer was notified to package and transport the device.
The gauge was a Texas Nuclear Model 5193 S/N Bi449.

AGREEMENT STATE REPORT INVOLVING AN UNDER-DOSE
The following report was received from the State of Virginia via fax:
On June 8, 2011, a prostate implant procedure was performed utilizing 57 seeds of 0.406 mCi/seed to a gland size of 33.7 cc. The intended dose was 145 Gy. On August 2nd during a post-plan evaluation, a CT was performed where it was discovered the base of the prostate was under-dosed. It is estimated that all 57 seeds are 1 cm short of the far superior position. The prescribed minimum D-90 dose was 80 Gy, a calculation was performed estimating that the actual dose delivered was 51 Gy. The physician and patient have been notified. A follow-up visit has been scheduled.
Virginia Event Report ID No.: VA-11-06
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
