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.

NOTIFICATION UNDER 10 CFR PART 21 OF BETTIS BRAND SEISMIC QUALIFIED G SERIES SPRING RETURN ACTUATORS
The following report was received via fax:
"Pursuant to 10 CFR Part 21, Valve Automation, Inc. (VAI) is writing to inform the Nuclear Regulatory Commission that, due to a retroactive application of a more stringent parts classification analysis, the adaptor plate contained in Bettis Brand Seismic Qualified G Series Spring Return Actuators (the 'Affected Actuators') is now classified as 'critical,' and therefore subject to certain inspection and dedication requirements which may not have been satisfied in Affected Actuators sold in the period between 2010 and 2016.
"VAI has not received any information that absence of the inspection and dedication activities as a result of the prior classification has resulted in a safety hazard. In addition, VAI does not have the ability to determine whether or not a defect or non-compliance as defined in Part 21 exists. We are notifying customers and recommending remedial inspection of the Affected Actuators.

"2.0 Identification of the basic component at issue:
Adaptor plates bearing the following part numbers:
VA600688
VA600692
VA600873
VA600988
"3.0 Nature of the issue:
VAI is not aware of a 'defect' in the adapter plates of Affected Actuators, but due to a retroactive application of a more stringent parts classification analysis, an inspection and dedication noncompliance may exist concerning these adaptor plates.
"4.0 Number and location of affected components in use:
42 Affected Actuators, sold to direct customers located in the United States.
"5.0 Date the issue was discovered:
March 14, 2017
"6.0 Corrective action and advice given to purchasers:
Inspection Recommendation
Certain measurements should be taken to remedy the inspection nonconformance. All measurements may be taken in situ with the actuator assembled to the valve. Please refer to Figure A (attached) depicting the feature to be measured. The numbered measurements in Figure A correspond to the numbered measurement inspection procedure below. Table 1 provides measurement values for reference [Figure A and Table 1 were supplied with the original submittal and may be viewed at https://www.nrc.gov/reading-rm/doc-collections/event-status/part21/ when posted]. Remedial inspection recommendations are to:
1. Confirm the thickness of the plate at the point where the bolt head & washer engage the flange surface. This location may be a milled flat section or counter sunk hole depending on the actuator size.
2. Verify full thread engagement for nuts installed on bolts for the housing flange.
3. Perform hardness testing on a small area on the outside diameter of the adaptor plate. The paint will need to be removed at the point of hardness testing.
Should the adaptor plate fail to meet the above specifications, please contact us promptly.
"7.0 Other advice to purchasers:
VAI recommends that users review applications where any Affected Actuators are used to determine any safety considerations in the operation of the plant.
"VAI is committed to the highest standards of safety and customer service in the nuclear industry, and remains dedicated to the supply of world class products to our customers. If you have any questions or require additional information related to this issue, please contact: Justin DeClue, Director of Global Quality, [Tel:] 281 477 4631."
