| Event Text PART-21 REPORT - CLOSED SWITCH NOT ACTUATING WHEN VALVE IS FULLY CLOSED
The following is a summary of a submitted facsimile:
"Items subject to this Fisher Information Notice (FIN) were provided to Catawba Nuclear Station (CNS) per CNS Order 00178457 (Fisher Order Number 033-D800306145). Specifically, Fisher supplied an 8 inch Design A11 Butterfly Valve with a Type 1052 Actuator and TopWorx Switches, serial number F000458892 ('Equipment'). The issue is with the closed switch not actuating when the valve is fully closed.
"The purpose of this FIN is to alert CNS that as of 2 September 2015, Fisher Controls International LLC (Fisher) became aware of a situation which may affect the performance of the Equipment, including its safety-related function.
"If there are any technical questions or concerns, please contact: Ben Ahrens, Quality Manager, Emerson Process Management, Fisher Controls International LLC, 301 South 1st Avenue, Marshalltown, La 50158, Phone: (641) 754-2249, benjamin.ahrens@emerson.com"

"This is a non-emergency, information only notification to the NRCOC. Plant conditions are as follows: Unit 3 is de-fueled and Unit 4 is in Mode 1 [At 100 percent power]. The Unit 3 Startup transformer is INOPERABLE due to preplanned maintenance. The 3B Emergency Diesel Generator (EDG) became INOPERABLE due to loss of all 480V vital AC load centers on Unit 3.
"With Unit 4 in Mode 1, Technical Specification [TS] 3.8.1.1.c requires a 4-hour report to the NRC due to inoperability of 1 of 3 required EDGs onsite, concurrent with inoperability of a required Startup transformer. This report is for informational purposes only and is not required by 10CFR50.72/73.
"Spent Fuel Pool Cooling at Unit 3 remains available via 3B SFP Cooling Pump which is powered from Unit 4."
The loss of the Unit 3 480V AC load centers is still under investigation. TS 3.8.1.1.c requires Unit 4 to exit the TS action statement in 2 hours or shutdown. To exit this TS, no two battery chargers may be powered from the same motor control center. The 480V vital AC load centers for Unit 3 must be restored since Unit 4 requires at least one train from Unit 3 480V AC load centers. The licensee is in the process of performing those actions.
The licensee notified the NRC Resident Inspector. |

"On November 5, 2015 at approximately 1000 EST, the Fermi 2 Integrated Plant Computer System (IPCS) was removed from service for planned maintenance on the Uninterruptible Power Supply (UPS) vital bus power supply. The Safety Parameter Display System (SPDS) resides on the IPCS platform and will be out of service and unavailable to Emergency Response Facilities (ERFs) during the time that IPCS is removed from service. The duration of work is expected to be approximately 48 hours. During this time dose assessment (Raddose) capability will only be available in the manual data input mode. The majority of the Control Room indications remain available to the plant staff 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 to the Operational Support Center, the Technical Support Center, and alternate facilities. The plant is currently in Mode 5, and will remain in Mode 5, for the duration of the IPCS and SPDS unavailability. 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, as described in NEI 13-01.
