AGREEMENT STATE REPORT - MINOR TRANSPORTATION EVENT
The following was received from the Washington State Department of Health (the department) via email:
"A hospital [Baptist Hospital of Miami, Miami, FL.] shipped unused brachytherapy seeds and GammaTiles back to the manufacturer, who is GT Medical Technologies. The manufacturer surveyed the returned package and measured about 14.6 mR/hour on the outside of the package instead of the typical reading of about 1.5 mR/hour.
"The manufacturer opened the package and found that the hospital did not follow the written instructions on how to pack return shipments. The top piece of foam packaging was not included in the package.
"The manufacturer found that, during transportation, two glass vials containing [cesium-131] reference brachytherapy seeds had escaped from their shielded storage container. The glass vials did not break and the seeds were still inside them. It was the unshielded seeds that caused the elevated reading on the outside of the package.
"The manufacturer notified the hospital, the [common] carrier, and the regulator [(the department)].
"The department expects to obtain additional information tomorrow about this event, and will provide an updated event report."

HIGH PRESSURE COOLANT INJECTION ISOLATION
The following information was provided by the licensee via fax or email:
"While performing a planned high pressure coolant injection (HPCI) system surveillance, an isolation signal was received based upon an exhaust rupture disc high pressure signal. This resulted in an unplanned inoperability of the HPCI system. All systems responded as expected, and the event is under investigation. No other systems were affected by this condition.
"This event is reportable as an 8-hour non-emergency notification under 10CFR50.72(b)(3)(v) as HPCI is a single train safety system. There was no impact to plant personnel or the public as a result of this condition. The NRC resident has been notified of this condition."
