PART 21 NOTIFICATION - EVALUATION OF A DEVIATION - STARTER CONTACTOR FAILURE

"Pursuant to 10 CFR Part 21, this is a non-emergency notification by Energy Northwest concerning a defect in Size 1 Freedom Series Starters with nominal 120 VAC coils manufactured by AZZ/NLI [Nuclear Logistics Inc.] used at Columbia Generating Station.

"On February 8, 2017 Energy Northwest was notified by NLI of a deviation associated with starter contactors used at Columbia that failed to close due to overheating of the starter coil. The coils that were provided were determined to not meet specified voltage ratings.

"The evaluation completed by Energy Northwest on March 14, 2017 concluded that the deviation did create a Substantial Safety Hazard, and is reportable under 10 CFR 21.21(d)(1) as a defect.

"A 30 day report will be issued by April 13, 2017 per 10 CFR 21.21(d)(4)."

The licensee performed a prompt operability assessment for the two starters currently installed.

The licensee will notify the NRC Resident Inspector.
