Section XI -- 25 years of development
- ABB Combustion Engineering Nuclear Operations, Windsor, CT (United States)
The original concept of nuclear power plant designers was that the higher standards of design and fabrication would make inservice inspections unnecessary, and little attention was given to provisions for access. By 1966 the Atomic Energy Commission recognized that a planned program of periodic inservice inspections would be needed. They began development of criteria, and encouraged industry code-writing organizations to do likewise. These groups joined forces in 1968, and their product was published by ASME in 1970 as part of the Boiler and Pressure Code, Section XI, Rules for Inservice Inspection of Nuclear Reactor Coolant Systems. Section XI, 24 pages in 1970, is now 723 pages. While it originally covered only light water reactor Class 1 components and piping, it now includes Class 2, 3, and containment, and liquid metal cooled reactor plants. Along the way, rules have been developed for gas-cooled and low pressure heavy water reactor plants. The growth in size of Section XI from its modest beginning has been largely because of recognition that the rules governing plant inspection/operation need to be considerably different from the rules provided for the component designer/manufacturer. Rules have been developed in the areas of repair/replacement technology, NDE methodology, NDE acceptance standards, and analytical evaluation methods in the absence of appropriate rules in Section III.
