CP applicants for which SERs were issued after July 1, 1974, were required by the NRC to qualify all safety-
related equipment to IEEE 323.[1] From the time this standard was originated, the industry developed methods that were used to qualify equipment in accordance with the standard. However, some of these methods had not been resolved to the satisfaction of the NRC.
In order to expedite the review and assess the adequacy of the equipment qualification methods and acceptance criteria used by NSSS and BOP vendors, the NRC determined that a generic approach was required. This item
was originally identified in NUREG-0371[2] and was later determined to be a USI in NUREG-0510.[3]
This USI was RESOLVED with the publication of NUREG-0588.[4] A new rule affecting future plants was also issued. MPA B-60 was established by DL/NRR for implementation of the solution at operating plants.
