Nuclear plant piping criteria and construction costs: Final report

A workshop on Nuclear Power Piping Constructibility attended by architect-engineers, utilities, fabricators, and nuclear steam system suppliers has identified cost-reducing modifications and improvements in the design and construction of piping systems. Among the measures that can reduce piping costs are: stabilization of design practices and regulations, improvement of acceptance criteria for as-built piping tolerances, reduction of piping supports, increased use of computer-aided construction, and reduction of field changes by making welding acceptance criteria more realistic. Participants categorized and prioritized areas for recommended industry actions involving either available and advanced technology
