ns allowed by 10 CFR Part 52. Although a COL applicant is not required to conform to this guidance, its use will facilitate both the preparation of a COLA by the applicant and the timely review of the application by the NRC staff. Much of this guidance also applies to ITAAC for an ESP and standard DC. The history of ITAAC is coupled with the history of nuclear power plant standardization, particularly with the standardization of the processes for issuing COLs. Many first-time nuclear plant applicants, designers, and consultants and many novel design concepts emerged in the early commercial nuclear power industry. Accordingly, the agency structured the 10 CFR Part 50 licensing process to allow it to make licensing decisions while design work was still in progress and focus reviews on individual plant-specific and site-specific considerations. The NRC commonly issued construction permits with the understanding that open safety issues would be addressed and resolved during construction and that issuance of a construction permit did not constitute the Commission’s approval of any design feature. Consequently, the operating license application review became very broad in scope. A fundamental premise of 10 CFR Part 52 is that, with a mature nuclear industry, it is possible to describe and evaluate nuclear power plant designs on a generic basis and to have designs that are essentially complete in scope and level of detail before construction. An “essentially complete nuclear power plant design” is defined as a design that includes all the SSCs that can affect the safe operation of the plant, except for site-specific features such as the service water intake structure and ultimate heat sink. An essentially complete design is a design that has been finalized to the point that procurement specifications and construction and installation specifications can be completed and made available for audit if the NRC determines that they are required for the Commission’s review
