ACCIDENT MITIGATION - MAIN STEAM SAFETY VALVES NOT ADEQUATELY PROTECTED FROM TORNADO MISSILES
"During an evaluation of protection for Technical Specification (TS) equipment from the damaging effects of tornados, Harris Nuclear Plant personnel identified conditions in the plant design such that specific TS equipment is considered not adequately protected from tornado missiles. A tornado could generate multiple missiles capable of striking exhaust piping on multiple main steam safety valves (MSSVs), resulting in crimping of the piping that could impact flow capacity and render the MSSVs inoperable. If the tornado caused a loss of offsite power, the MSSVs are credited to remove decay heat to achieve cold shutdown. Compensatory measures have been implemented to ensure safety in the event of a tornado.
"Enforcement discretion per Enforcement Guidance Memorandum EGM 15-002 and Interim Staff Guidance DSS-ISG-2016-01 has been implemented and required actions taken. Corrective actions will be documented in a follow-on licensee event report."
The licensee has notified the NRC Resident Inspector.

AGREEMENT STATE REPORT - TOTAL DOSE DELIVERED DIFFERS FROM THE PRESCRIBED DOSE
The following report was received from the California Department of Public Health, Radiation Health Branch (RHB) via email:
"RHB North was informed by the Radiation Safety Officer of UC [University of California] Davis Medical Center, of a Medical Event that took place on July 7, 2016. The Medical Event involved a SirSphere case. The patient received 29 per cent more than the prescribed dose. The physicians working on the case as well as the referring physician and the patient have been notified. There are no expected negative impacts on the patient.
"Prescribed dosage: 13.5 mCi. Administered dosage: 17.4 mCi.
"The apparent reason of the misadministration is that the CNMT [Certified Nuclear Medicine Technologist] miscalculated the dosage required."
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.

LOSS OF TONE ALERT RADIO SYSTEM TOWER
"At 0610 CDT on 7/7/2016, Cooper Nuclear Station confirmed that the Shubert radio transmission tower was not functioning. This affects the tone alert radios used to notify the public in the event of an emergency condition. This is considered to be a major loss of the public prompt notification system capability and is reportable under 10CFR50.72(b)(3)(xiii).
"Nemaha, Richardson and Atchison county authorities within the 10 mile EPZ were notified of the condition and the effect on the tone alert radios and will utilize the backup notification method making this condition reportable under 10CFR50.72(b)(2)(xi) for notification of other government agencies.
"Estimated return to service time is unknown. The cause of the failure is unknown.
"The NRC Resident Inspector has been notified of this condition."
