Title	Potential Failure of Sbm Type Switches
Event Description	The following is a summary of information that was provided by the reporting organization via facsimile: Pursuant to 10 CFR 21.21 (b), AZZ - NLI [AZZ - Nuclear Logistics Inc.] has provided written notification to the affected licensees of the potential failure of GEH SBM type switches manufactured (by GEH) [General Electric - Hitachi] in the period from January 2012 to December 2014. This condition has been reported in GEH document SC 14-19 (dated Dec. 11, 2014) in which GEH notified their affected licensees of the potential failure of SBM type switches, manufactured and shipped January 2012 through December 2014, due to incorrect installation of a conical spring. AZZ - NLI procured and dedicated commercial grade SBM type switches, manufactured during this time-frame, and subsequently provided to: Exelon - Peach Bottom; OPPD - Fort Calhoun; TVA- Watts Bar; KHNP [Korea Hydro & Nuclear Power]. On the basis of our evaluation, it is determined that AZZ - NLI does not have sufficient information to determine if the subject condition would, or has, created a Substantial Safety Hazard or would have created a Technical Specification Safety Limit violation as it relates to the subject plant applications. Therefore, purchasers are being advised to perform a visual inspection of the switches at the earliest opportunity to determine if the condition exists. The following information is provided per 10 CFR 21.21(d) (4). Name and address of the individual or individuals informing the Commission: Tracy Bolt, Director of Quality Assurance, AZZ - Nuclear Logistics Inc., 7410 Pebble Drive, Ft. Worth, TX 76118
