Title	Part 21 Notification - Inadequate Dedication of Relays
Event Description	On March 13, NextEra Energy completed its evaluation of a deviation concerning relays dedicated at its Corporate Procurement Engineering & Dedication Facility and concluded that the condition represented a defect under 10 CFR 21. The defect was discovered on January 16, 2018 during pre-installation bench testing. During that bench test, some of the relays exhibited contact chatter. Upon review of the dedication, it was identified that contact chatter had been noted at reduced voltage, and that the condition was improperly dispositioned as acceptable. That conclusion was incorrect as the relays are DC powered and may be required to operate under reduced voltage conditions. The affected relays were supplied to the Seabrook Nuclear Power Station. None of those relays were installed and all have been quarantined to prevent installation. Dedicating Entity: NextEra Energy Integrated Supply Chain - Corporate Procurement Engineering & Dedication Facility, West Palm Beach, FL Device: GE Relay, base model CR120BD NextEra expects to complete their evaluation by April 14, 2018.
