70.50(b)(2) - SAFETY EQUIPMENT FAILURE

| Event Text OFFICE AREA ALARM AUDIBILITY DISABLED
"On December 1, 2016, at 1014 hours (EST), the speakers for a portion of the bottom floor of Building 305, office and lunch room areas, were inadvertently disabled during construction activities to remove obsolete equipment. Special Nuclear Material (SNM) is not processed, handled, or stored within the areas where the speaker system was disabled; however, these areas require evacuation in the unlikely event of a nuclear criticality accident as described in the NFS [Nuclear Fuel Services] Emergency Plan.
"There were no actual radiological or other nuclear safety consequences. The potential consequence was that in the event of a nuclear criticality accident, evacuation could have been delayed for those personnel within these areas with a resultant increase of postulated doses. Additionally, awareness of a fire event could have been delayed for these same personnel. A series of compensatory actions were taken including restricting access to the affected areas to essential personnel, and establishing radio communications between the personnel in these areas and the personnel continuously monitoring the alarm station panel.
"On December 1, 2016, at approximately 1159 hours (EST), full compliance was restored by repairing a disabled cable in the speaker circuit and by successfully performing a speaker system test in the affected areas.
"The licensee notified the NRC Resident Inspector on. December 1, 2016." |

"At 2240 [CST], December 16, 2016, it was identified that HV-SW-(SF-C-1A)(CS), control switch for supply fan SF-C-1A for HV-FAN-(SF-C-1A), main control room A/C unit supply fan had been inadvertently been placed to OFF, leaving no supply fan running as required to maintain CREFS [Control Room Emergency Filtration System] operable. This was discovered following the performance of 6.1HV.302 Essential Control Building Ventilation Functional Test (DIV 1).
"It is estimated that the control switch was placed in OFF at approximately 2220 during preparation of 6.1HV.302 per S.O.P. 2.2.38. Time of discovery was 2240. This resulted in an unplanned LCO entry for the CREFS. CREFS was subsequently declared inoperable and LCO 3.7.4 Condition A was entered, with required action A.1 to restore CREFS to operable status within 7 days. The switch was restored to its required position at 2247 and CREFS was subsequently declared operable and the referenced LCO was exited.
"CR-CNS-2016-08744 was written to document the unplanned inoperability."

"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 condition impacting functionality of the Technical Support Center (TSC) Ventilation System was discovered on December 8, 2016, at 1330 [EST]. The issue involved a loss of the ability to maintain habitability of the TSC due to a failed outside air intake fan. The repair of the equipment failure is currently being planned.
"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable due to ambient temperature, radiological, or other conditions. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to an alternate location in accordance with applicable site procedures. The secondary TSC has been notified that relocation may be necessary upon facility activation. This condition does not affect the health and safety of the public or station employees.
"The NRC Resident Inspector has been notified." | |
