BUS GROUND ON HOUSE SERVICE TRANSFORMER 4160V VITAL BUS TRANSFORMER
At 2120 CT Ft. Calhoun Station control room received an alarm indicating a T1A3 4160V Bus Ground on house service transformer 4160V vital bus 1A3 transformer. Licensee referenced ARP and plant AOP's 31 and 32, for all 4160V buses fed from 22KV and Loss of 4160V bus power. Subsequent securing of possible 4160V bus loads did not isolate the ground. Subsequently transferred 4160V bus 1A3 feed from 4160V transformer T1A3 to 22KV Transformer T1A1. Alarm and ground indications went away upon transfer. Per Technical Specification 2.7.(2)b Nuclear Regulatory Commission Operations Control Center shall be notified within 4 hours of transformer inoperability. System Engineering and Electrical Support Staff are on site investigating. Plant is in a severe thunderstorm warning until 2300 CT. Diesel operability has been verified.
The NRC Resident Inspector was notified of this event by the licensee.

"Following a root cause investigation it was determined that the event of June 10, 2002, did not result in the inoperability of either house service transformer T1A-3, or vital bus 1 A3. The misdiagnosis of the event was caused by a disconnected ground detector. The ground was on a 4160 to 480 volt vital transformer and did not result in the inoperability of plant equipment."
The licensee notified the NRC Resident Inspector. The R4DO (Dale Powers) has been notified.

PART 21 ON ROTORK NA1 ACTUATOR
The name of the manufacturer is Rotork Controls, Inc. The defective components the Rotork NA1 type electric Valve Actuators fitted with an Add-on-Pak 1 (AOP1) Assembly which was manufactured between 1978 and October 2001 and have a safety function used for end of travel indication. The problem is that moulded components within the AOP1 assembly cannot be confirmed to the same specifications as those originally tested and qualified at Wyle in 1978. No list of affected plants was available at this time.
