The following notification is an excerpt from the received report:
Westinghouse nuclear steam supply system (NSSS) plants that have thermal sleeves in the control rod drive mechanism (CRDM) penetration tubes, wear of the thermal sleeve flange against the tube could have safety consequences that were not previously considered. Recent operating experience, during startup procedures at an Electricite de France (EdF) plant, has shown the possibility for the flange remnant from a thermal sleeve to interfere with control rod movement.
Potential affected plants include, A. W. Vogtle 1 & 2, Braidwood 1 & 2, Byron 1 & 2, Callaway, Catawba 1 & 2, Comanche Peak 1 & 2, Diablo Canyon 1 & 2, McGuire 1 & 2, Millstone 3, Seabrook, Sequoyah 1 & 2, Shearon Harris, South Texas 1 & 2, Watts Bar 1 & 2, Wolf Creek, Beaver Valley 1 & 2, D.C. Cook 1 & 2, Indian Point 2 & 3, North Anna 1 & 2, Point Beach 1 & 2, Prairie Island 1 & 2, R. E. Ginna, Salem 1 & 2, Surry 1 & 2, and Turkey Point 3 & 4.
