AGREEMENT STATE REPORT - PATIENT RECEIVED LESS THAN PRESCRIBED DOSE
The following report was received from the California Department of Public Health via email:
"[The licensee reported to the State of California that a] patient [was] receiving Y-90 treatment to the right lobe of liver with Theraspheres. (10CFR35.1000). The prescribed dose was 100-150 Gray, actual dose received was 63.4 Gray. The targeting vessel was 'flowing slowly' causing Theraspheres to 'settle out' prior to reaching target. Preliminary findings suggest that the underdose was due to the physical condition of patient, not through any fault of the medical physicist or licensee.
"No adverse outcomes are expected for the patient. Medical physicist and physicians [are] evaluating whether or not retreatment is necessary."
California Report Number: 073014.
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.

DAMAGED MOISTURE/DENSITY GAUGE
A moisture/density gauge was damaged by Lullr construction equipment at the Civil Affairs Battalion Complex on Fort Bragg Military Base. The source rod was not damaged and the damage was mostly to the electronics portion. The RSO performed surveys of the gauge and no abnormal dose rates were observed.
The gauge is a Troxler Model 3430 moisture/density gauge and typically contains 8 mCi of Cs-137 and 40 mCi of Am-241/Be.

DAMAGED MOISTURE/DENSITY GAUGE
With the moisture/density gauge still on the ground after performing a standard count, the licensee Radiation Safety Officer backed over the gauge with his pickup truck. The source was not exposed at the time and the source remained shielded. Damage noted to the gauge was a broken shaft that sets the depth of test which is also part of the handle along with some surface scarring to the gauge housing. The gauge was checked with a survey meter for leakage from the sources. At one meter the survey meter reading was less than 0.2 mrem/hr which is comparable to a non-damaged gauge. A leak test wipe was also performed and sent to Humboldt Mfg. for measurement. The gauge was transported and placed in its secure storage location until a determination has been made on how repairs will be accomplished.
The gauge is a Humboldt Model 5001 moisture/density gauge containing 10 mCi Cs-137 and 40 mCi Am-241/Be.

ULTIMATE HEAT SINK IN AN UNANALYZED CONDITION
"On July 30, 2014, at [0940 CDT], with the plant operating at 100% power, a review of an engineering analysis of the ultimate heat sink (UHS) determined that the UHS had been in an unanalyzed condition that degraded plant safety. This condition was the result of a design basis deficiency for the UHS that did not account for the adverse effects of system leakage on compliance with the 30-day inventory required by Regulatory Guide 1.27. The system design basis requires that 30-day inventory be maintained, with the assumption that no replenishment of the UHS occurs for the entire duration of the postulated event.
"In support of the development of the engineering analysis, compensatory measures have been implemented which provide adequate assurance that the UHS will perform its design safety function. Corrective actions to restore full compliance with design basis requirements are in development.
"This event is being reported in accordance with 10 CFR 50.72 (b)(3)(ii) as an unanalyzed condition that degraded the safety function of the UHS."
The licensee notified the NRC Resident Inspector.
