AGREEMENT STATE REPORT - IRRADIATOR DRAWER STUCK IN INTERMEDIATE POSITION

"On June 9, 2017 it was reported to the department that, following a routine irradiation of two samples, the drawer containing the irradiated material ground to a halt while being raised from the irradiation position. The drawer is currently stuck in an intermediate position. Following the halting of the device, the licensee immediately removed it from service and contacted the manufacturer to schedule servicing of the device. Area monitors indicate that there are no elevated radiation levels. The device is J.L. Shepherd Model 143-45-C irradiator. The department will dispatch inspectors to perform an investigation."

PRIMARY CONTAINMENT DECLARED INOPERABLE DUE TO FAILURE OF DRYWELL TO SUPPRESSION CHAMBER VACUUM BREAKER TO FULLY CLOSE

"This report is being made pursuant to 10 CFR 50.72(b)(3)(v)(D), 'any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.'

"At time 2115 CDT on June 19, 2017, one torus to drywell vacuum breaker failed to indicate that it was closed after being cycled for surveillance testing. The vacuum breaker had been cycled open and then closed to satisfy SR 3.6.1.8.2 - Perform a functional test of each required vacuum breaker. Failure of the vacuum breaker to indicate closed after the control switch was taken to the closed position represents a failure to satisfy SR 3.6.1.8.2 and SR 3.6.1.8.1 - Verify each vacuum breaker is closed. Primary containment is allowed to have a bypass area between the drywell and suppression chamber less than or equivalent to a one inch diameter hole. The are of bypass was indeterminate while the vacuum breaker did not indicate fully closed. Primary containment was declared inoperable during the time the vacuum breaker did not indicate fully closed.

"The vacuum breaker control switch was subsequently cycled open and closed one additional time. At time 2311 CDT, the vacuum breaker indicated fully closed. At that time, primary containment was declared operable.

"Currently, all twelve Drywell to Suppression Chamber vacuum relief valves are closed and in the normal line-up.

"The NRC Senior Resident Inspector has been notified."
