PART 21 REPORT
A potential safety condition was reported which may exist with the Eaton Cutler-Hammer Type W Vintage Unit plug in stabs. On July 3, 2003, Framatome ANP, Inc - Electrical Products received from Eaton Cutler-Hammer an Eaton Cutler-Hammer Type W Vintage Unit Product Advisory, dated June 27, 2003. The advisory warns that the condition exists when a unit of a particular Manufacturing Date Code range is withdrawn from a Motor Control Center structure. Under this condition, the clip holding the stab finger in place may dislodge. As a result, the stab finger remains plugged onto the vertical bus until the breaker cable connection forces the stab finger off the bus. The potential of a unit being extracted from live bus may cause arcing or single phasing or risk of personal injury, death or property damage.
On July 3, 2003, Framatome ANP, Inc. - Electrical Products determined that the defective Eaton Cutler-Hammer Type W Vintage Unit Plug in Stabs were supplied as a Safety Related component installed in Safety Related Type W MCC Buckets to only one Nuclear Customer. On July 3, 2003, Framatome ANP, Inc. - Electrical Products notified the Point Beach Nuclear Plant (Nuclear Management Company). Corrective actions implemented by Framatome ANP, Inc. - Electrical Products included the replacement of thirteen (13) Type W Stab Assemblies, with new Type W Stab Assemblies manufactured by Eaton Cutler-Hammer with "updated clips" (clips with wings) at the Point Beach Nuclear Plant Site on July 11, 2003.
