April 3, 2018 U.S. Nuclear Regulatoty Commission ATIN: Document ConttolDesk Washington, DC20555-0001
Subject:
NextEra Energy'- Integrated Supply Chain-Dedicating Entity West Palm Beach, Florida Part 21 Notification - General Electric CR120BD Relay In accordance with 10 CFR 21.21 ( d)(3)(ii), N extEra Energy is providing the required written notification of the identification of a defect in General Electric (GE) Type CR120BD Relay. This information was initially reported to the NRC Operations Center on March 15, 2018 (i.e., Event Number 53262). The enclosure to this letter provides the information required by 10 CFR 21.21(d)(4).
This document contains no regulatoty commitments.
Sincerely, J3~J-.~
David Peterson Director - Integrated Supply Chain - Technical Services AAL
Enclosure:
30-Day Notification Per 10 CFR 21.21(d)(3)(ii)
Florida Power & Light Company 700 Universe Boulevard, Juno Beac;h, FL 33408
30 Day Notification per 10 CFR 21.21(d)(3)(ii)
- 1.
Name and address of the individual or individuals informing the Commission.
David Peterson Director - Integrated Supply Chain - Technical Services NextEra Energy (NEE) 2456 Port West Blvd West Palm Beach, Florida 33407 ii.
Identification of the facility, the activity, or the basic component supplied fot such facility or such activity within the United States which fails to comply or contains a defect.
Basic Component:
General Electrical (GE) Type CRJ 20BD Relay (l 25VDC relay with 6 normally open and 2 normally closed contacts) was dedicated for safety related application at Seabrook Station 111.
Identification of the firm constructing the facility or supplying the basic component which fails to comply or contains a defect.
Facility (Dedicating Entity):
NextEra Energy (NEE) Integrated Supply Chain-Technical Services (ISC-TS)
Corporate Procurement Engineering & Dedication (CPED) Facility West Palm Beach, Florida 33407 NEE JSC-TS procured GE Part Number CR120BD06141 relays commercial grade and performed commercial grade dedication (CGD) of the items/or U$e in safety related applications at Seabrook Station.
iv.
Nature of the defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply.
The commercial grade relays were provided by commercial supplier (General Supply &
Services Inc. -PO 02350829) from Parts Super Center (PSC) as GE Part Number CR120BD06141.
The following table provides the purchase order numbers, quantities, and date received associated with the affected relays.

On January 16, 2018, during the performance of bench calibration of GE Type CRJ 20BD relay at Seabrook, the relay failed to operate reliably during the 100 cycles test at l 25VDC. When energized the relay coil made a loud noise and the contacts chattered excessively. Bench calibration process was ceased and condition report written.
ISC-TC was contacted and after further investigation, it was determined that during pe,formance of the commercial grade dedication plan, the relays were subjected to a 90VDC pickup voltage test, during which three relays had chatter and the test was stopped The test results were documented via NEE Discrepancy Report and subsequently dispositioned as acceptable.
The disposition of acceptance was documented by the procurement engineer based.on engineeringjudgment and resulted in removal of the 90VDC pickup voltage test.
Review of NEE parts database identified that GE CRJ20BD relays are required to meet the modification specifications, which states, in part, that a 125 VDC relay is to have a minimumpickup voltage of90 VDC.
The failure of the three relays to successfully pass the 90VDC pickup test is considered a deviation from the design specification.
Based on review of EDG control circuits, a failure of this relay, like the one that occurred during the bench testing, could prevent the safety related Emergency Diesel Generator (EDG) from starting and loading.
- v.
The date on which the information of such defect or failure to comply was obtained.
Date of Discovery January 16, 2018 Seabrook site personnel provided prelimina1y evaluation of the condition and JSC-TS completed the evaluation concluding reportability pursuant to 10 CFR Part 21 on March 13, 2018.
NRC was notified by telephone on March 15, 2018 (ref EN 53262).
v1.
In the case of a basic component which contains a defect or fails to comply, the number and location of these components in use at, supplied for, being supplied for, or may be supplied for, manufactured, or being manufactured for one or more facilities or activities subject to the regulations in this part.
