| Title | Part 21 - Potential Defect in General Electric Sb1 Switches and Hea Relays |
| Event Description | {{#Wiki_filter:The following is an excerpt from a fax received from United Controls International (UCI):
The purpose of this letter is to provide the NRC with a report in general conformity of the requirements of 10CFR Part 21.21. On March 19, 2013, United Controls Issued an Interim letter regarding a discovered manufacturing change in the contact assembly of General Electric SBM series switches. Since 2009, the manufacturing process of the contact assembly of the SBM switch contacts has changed to have the whole assembly (contact holder and contact tip) tin plated. This was discovered while investigating an SBM switch that failed at a customer site due to high contact resistance across closed contacts. The finding that there was a manufacturing process change in the SBM switches lead to further discussions and evaluations regarding equipment of similar design. General Electric SB1 series switches and HEA series relays use the same contact arrangement design as the SBM series switches. The contact assemblies of the SB1 switches and HEA relays are subject to the same tin plating process of the contact assembly as previously reported on the SBM series switches. At this time, UCI is unable to evaluate if this manufacturing change may have an adverse effect on the capability of the General Electric SB1 switches and GE HEA relays to perform in their intended safety related application. UCI will notify the affected Utilities to our findings. The affected Part Number, Utility, Order Number and Quantity is listed below: Part Number 12HEA61B23SX2; Utility CFE; Order 700372018; Quantity 3 Part Number 12HEA61C236X2; Utility FPL Turkey Point; Order 02260642-34; Quantity 2 Part Number 12HEA61C237; Utility OPPD; Order 180520; Quantity 4 Part Number 12HEA61C238X2; Utility OPPD; Order 180520; Quantity 3 Part Number 12HEA61C237; Utility OPPD; Order 185929; Quantity 2 Part Number 12HEA61C237X2; Utility OPPD; Order 188314; Quantity 2 Part Number 12HEA63C239X2; Utility FPL St. Lucie; Order 02260642-41; Quantity 8 Part Number HEA61C234X2; Utility Antung; Order PP100204; Quantity 2 Part Number HEA61C244X2; Utility OPPD; Order 179664; Quantity 5 Part Number HEA61C241X2; Utility OPPD; Order 179664; Quantity 2 Part Number HEA63C239X2; Utility FPL St. Lucie; Order 02260642-103; Quantity 3 Part Number 12HEA61C238X2; Utility OPPD; Order 194686; Quantity 4 Part Number 16SB1BB339STS2P; Utility Duke Oconee; Order 156606; Quantity 11 Part Number 165BlFB2C85SWM2Y; Utility Nextera Seabrook; Order 2259825-3; Quantity 1 Part Number 16SB1LB2C01LSM2P; Utility CFE; Order 700327408; Quantity 3 Utility CFE is the Comisi�n Federal de Electricidad (Mexico) and Utility Antung is located in Taiwan.
