AGREEMENT STATE REPORT - Y-90 SIR-SPHERE UNDER DOSE OF 87%
"The licensee notified the Department [Ohio Department of Health] on March 20, 2013 of a medical event that occurred on March 19, 2013 involving a Y-90 SIR-Sphere patient treatment. The delivery system became clogged and delivered only 3.2 mCi (13%) of the 24.3 mCi prescribed activity. The cause of the event is under investigation. The licensee plans on retreating the patient."
Ohio Item Number: OH130002
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.

MANUAL REACTOR SCRAM DUE TO LOWERING CONDENSER VACUUM
"At 0402 [CDT] on 03/19/2013, the Unit 1 reactor was manually scrammed due to lowering main condenser vacuum. The cause of the loss of vacuum was a significant leak on the 1C feedwater heater level control line. The leak appeared as a steam/water leak near the penetration to the main condenser. As extraction steam was isolated, condenser vacuum deteriorated and was approaching the turbine trip setpoint, at which time the reactor was manually scrammed. Condenser vacuum recovered following the scram. MSIVs [Main Steam Isolation Valves] are open, main turbine bypass valves are controlling reactor pressure and reactor feedwater pumps are being used to control reactor water level.
"All expected containment isolation and initiation signals (Groups 2, 3, 6, and 8) were received. Upon receipt of these signals all required components actuated as required. In response to the scram, all plant equipment responded as designed. The reactor had been operating near 95% power for several hours due to the 1C3 heater isolating at 2334 [hrs. CDT] on 3/18/13.
"This event is reportable within 4 hours per 10CFR50.72(b)(2)(iv)(B) `any event or condition that results in actuation of the reactor protection system (RPS) when the reactor is critical except when the actuation results from and is part of a pre-planned sequence during testing or reactor operation.' It is also reportable within 8 hours per 10CFR50.72(b)(3)(iv)(A) and requires an LER within 60 days per 10CFR50.73(a)(2)(iv)(A)."
All rods inserted into the core during the scram. No safety relief valves lifted during the transient. The plant is in its normal shutdown electrical lineup. The licensee has notified the NRC Resident Inspector.

TSC VENTILATION REMOVED FROM SERVICE FOR PLANNED MAINTENANCE
"On March 19, 2013, at 0830 hours [CDT], the Kewaunee Power Station Technical Support Center (TSC) ventilation system was removed from service for planned TSC ventilation system maintenance. The removal of the ventilation system potentially affects the TSC habitability during a declared emergency requiring activation. The Emergency Response Organization (ERO) team has been notified of the maintenance and the possible need to relocate during an emergency. If an emergency is declared and TSC ERO activation is required, the TSC will be staffed and activated unless the TSC becomes uninhabitable due to ambient temperatures, radiological, or other conditions. If relocation of the TSC staff becomes necessary, the Station Emergency Director will relocate the staff to an alternate TSC location.
"The ventilation system is expected to be out of service for approximately 5 hours.
"This condition is being reported in accordance with 10CFR50.72(b)(3)(xiii) as an event that results in a major loss of emergency assessment capability.
"The NRC Resident Inspector has been notified."
