TECHNICAL SUPPORT CENTER (TSC) AND EMERGENCY OPERATIONS FACILITY (EOF) VENTILATION SYSTEM OUT OF SERVICE
"This is a non-emergency eight hour notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) as the discovered condition affects the functionality of an emergency response facility.
"A deficiency with the TSC and EOF ventilation system was discovered on October 29, 2016 at 1032 [EDT]. The deficiency involved a fire alarm unable to be reset impeding the ability to place the TSC and EOF in recirculation mode in the event of a radiological release. The fire alarm was reset at 1204 [EDT] on October 29, 2016, restoring capability to perform full emergency assessment to the TSC and EOF.
"If an emergency had been declared while the fire alarm was unable to be reset requiring TSC or EOF activation during this period, the TSC and EOF would be staffed and activated using existing emergency planning procedures unless the TSC or EOF became uninhabitable due to ambient temperature. radiological, or other conditions. If relocation of the TSC or EOF became necessary, the Emergency Response Manager would relocate the TSC and/or EOF staff to an alternate location in accordance with applicable site procedures.
"This condition had no impact on the health and safety of the public.
"The NRC Resident Inspector has been notified."
A malfunctioning smoke detector was removed from the system. Compensatory measures are being employed.

AGREEMENT STATE REPORT - RADIOGRAPHER DOSIMETRY LEFT NEAR EXPOSURE DEVICE DURING RADIOGRAPHY SHOT
This report was received by the State of Washington via email:
"During preparation of a radiography exposure, the radiographer and another radiation worker from Bechtel, attempted to untangle their dosimetry from the camera apparatus. In doing so, they left their dosimetry next to the camera during a shot. The radiographer exposed his TLD [Thermo Luminescent Dosimetry] and pocket dosimeter, as well as a client's electronic dosimeter during the exposure. Their dosimetry minus the radiographer's rate alarm was left next to the camera during the exposure. The radiographer wears dosimetry issued by Northwest Inspection and their client, Bechtel, sub contractor of the US Department of Energy. The radiographer's pocket dosimeter was off scale. Bechtel's electronic dosimeter showed an exposure dose of 300 mrem. The radiographer reported the incident to the RSO [Radiation Safety Officer]. The radiographer's TLD was sent to the dosimetry processing facility. Additional training for the radiographer has already taken place. In view of the fact that no 'persons' were overexposed, a spare TLD will be issued to the radiographer and will be allowed to continue to work."
The radiography camera is a QSA Model Number A424-9, Serial Number 32886G, containing an Ir-192 34.5 Ci source.
