UNPLANNED LOSS OF EMERGENCY ASSESSMENT CAPABILITY
"CPNPP [Comanche Peak Nuclear Power Plant] experienced an unplanned loss of the seismic monitoring instrument on May 24, 2016 at 1022 [CDT]. The unplanned loss of the seismic monitor resulted in a loss of assessment capability for the HA1.1 (seismic event greater than operating basis earthquake) Alert emergency classification. The seismic monitor was restored to service on May 24, 2016 at 1043.
"This loss of assessment capability is reportable to the NRC within 8 hours of discovery in accordance with 10 CFR 50.72(b)(3)(xiii)."
The NRC Resident Inspector has been notified.
* * * UPDATE ON 6/2/16 AT 1630 EDT FROM ANTHONY PATE TO DONG PARK * * *
"On May 24, 2016 at 1748 [EDT], Comanche Peak reported an unplanned loss of emergency assessment capability per 10 CFR 50.72(b)(3)(xiii) [EN# 51955]. Specifically, Comanche Peak reported an unplanned loss of the seismic monitoring instrument. The unplanned loss of the seismic monitor would have resulted in a loss of assessment capability for the HA 1.1 (seismic event greater than operating basis earthquake) Alert emergency classification. The seismic monitor was restored to service on May 24, 2016 at 1043 [CDT].
"The engineering review determined that the alarms displayed on the seismic monitoring screen provides Operations awareness of the system status. Signals were still being received from the sensor and if there was an OBE [Operating Basis Earthquake] during the time the alarms were in, it would have displayed on the monitoring screen and on the Main Control Board by providing an OBE Exceedance alarm, maintaining emergency assessment capability. Therefore, Comanche Peak requests that the May 24, 2016, 10 CFR 50.72(b)(3)(xiii) reportable event for Units 1 & 2 be retracted."
The licensee will notify the NRC Resident Inspector.

AGREEMENT STATE REPORT - MEDICAL UNDERDOSE TO THE LEFT LOBE OF LIVER
The following report was received from the New York State Department of Health, Bureau of Environmental Radiation Protection via facsimile:
"Radiation safety staff from a hospital called on 5/24/2016 to report a medical event that meets the reportability criterion on the borderline. 79.5 percent of intended dose is believed to have been delivered to the left lobe of the liver of a patient receiving Y90 treatment. The patient had received treatment to the right lobe a month ago. The left lobe was smaller with small vessels. The waste measured after the procedure showed that only about 79 .5 percent had been delivered. The licensee usually is able to administer 95 percent of intended dose in this procedure. We were informed that since the amount retained in the device is about the same, smaller doses tend to show a greater percent in retained in the device. They will send a report within 7 days."
NYS NRC Event Report ID No.: NYDOH-16-02
NY State Incident No.: 1146
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.
