FAILED POWER SUPPLY AFFECTING RADIATION MONITORS

"At 0130 CST, a degraded power supply resulted in multiple Area Radiation Monitors (ARMs) reading erroneously low. As a result, this condition is reportable under 10 CFR 50.72(b)(3)(xiii) as these ARMs are used to assess NUE and Alert thresholds. Portable Radiation Monitors have been placed in identified affected areas as a compensatory measure.

"The health and safety of the public was maintained as the plant was in a normal condition with no initiating event in progress or signs of elevated radiation on any other unaffected radiation monitors.

"The NRC Resident Inspector has been notified."

INTEGRATED PLANT COMPUTER SYSTEM REMOVED FROM SERVICE FOR PLANNED MAINTENANCE

"[On] February 23, 2014, at approximately 1200 [EST], the Fermi 2 Integrated Plant Computer System (IPCS) was removed from service outside of the Control Room to support planned system maintenance. The Safety Parameters Display System (SPDS) and Emergency Response Data System (ERDS) reside on the IPCS platform and [was rendered] out of service when the IPCS [was] removed from Emergency Response Facilities (ERFs). These systems will be unavailable to all Emergency Response Facilities (ERFs) for approximately 50 hours. During this time, dose assessment (Raddose) capability will only be available in the manual data input mode. The SPDS indications and Raddose remain available to the plant staff in the Control Room, and will be used for emergency response, if needed. Information will be communicated to the NRC using other available communication systems as needed. A follow-up notification will be submitted when the IPCS is completely restored, including SPDS and ERDS, to the Operational Support Center, the Technical Support Center, and alternate facilities. This 8-hour non-emergency notification is being made per the requirements of 10 CFR 50.72(b)(3)(xiii), as an event that results in a major loss of emergency assessment capability."

The licensee has notified the NRC Resident Inspector.
