CRANE ITEM RELIED UPON FOR SAFETY NEVER INSTALLED
"During unrelated maintenance, it was discovered that the UUSA UBC crane was missing components that are within the IROFS27e, QL1 boundary. These components have been missing since the crane went into operation in early 2015. The IROFS [Item relied upon for safety] has been declared degraded and is currently inoperable, and in a location where it cannot impact licensed material.
"This IROFS is designed to mitigate the consequences of UF6 release, to meet 10 CFR 70.61 performance requirements. No accident occurred, no release occurred.
"During the period in which the crane was operating in a degraded state, no design basis accidents occurred, thus there are no actual consequences. The crane had been moved to a safe position in order to perform other repairs (away from licensed material), and it locked in a place, thereby removing applicability of the IROFS. Thus, there is currently no potential for consequences.
"During unrelated repair activities, it was discovered that the URENCO USA UBC Crane has been in operations since March of 2015 while in a degraded condition. A component within the IROFS QL1 boundary was never installed.
"This is a sole IROFS to mitigate consequences. There are no other IROFS in place to support this function. Currently there is no analysis available to support the ability of the degraded IROFS to perform its safety function.
"There were no design basis external events during operation of the crane, nor do any currently exist.
"The UBC Crane was already locked out for ongoing corrective maintenance, The lockout remains active, and the IROFS is now declared inoperable. The condition was entered into the USA's Correcting Action Program for Evaluation and Corrective Actions.
"The degraded IROFS has been declared inoperable. No accident sequences occurred.
"The plant did not enter an emergency classification, nor is one planned.
"There are no planned notifications other that this event notification to the NRC Operations Center."
The NRC Regional Inspector (Munson) was notified.

CONTROL ROOM EMERGENCY VENTILATION SYSTEM INOPERABLE
"On December 07, 2015, at 0825 hours (CST), the Control Room Emergency Ventilation (CREV) system was declared inoperable due to the Air Handling Unit (AHU) tripping upon attempting to swap from the non-safety related CR HVAC. Swapping was being performed to allow maintenance on the non-safety related system.
"Technical Specification 3.7.4, Condition A, was entered which requires the CREV system to be restored to an operable status in seven (7) days. Additionally, Technical Specification 3.7.5, Condition A, was entered which requires CREV AC to be restored to an operable status in 30 days.
"This notification is being made in accordance with 10 CFR 50.72(b)(3)(v)(D), 'Event or Condition That Could Have Prevented Fulfillment of a Safety Function,' because the CREV system is a single train system required to mitigate the consequences of an accident."
The NRC Resident Inspector was notified.
The Licensee notified the Illinois Emergency Management Association.
