Resolution of Generic Safety Issues: Item B-24: Seismic Qualification of Electrical and Mechanical Equipment ( NUREG-0933, Main Report with Supplements 1–34 )
The seismic qualification of complex electrical and mechanical components has undergone rapid changes in the past several years. Revisions in industry standards (IEEE 344) have resulted in the need to audit the qualification programs of NSSS vendors and architect/engineers to ascertain if components previously qualified using older requirements meet the new requirements. This NUREG-04713 task will include: (1) revising SRP11 Sections 3.9.2 and 3.10 to combine pertinent material, (2) continuing the generic audit of NSSS vendors and architect/engineers, and (3) compiling a listing of all equipment considered to be adequately qualified and identifying the level for which the qualification is acceptable.
This issue is covered in USI A-46, "Seismic Qualification of Equipment in Operating Plants."
