American National Standard


Book Description

ANS 58.9-1981 (R2020) provides criteria for the designer which interpret the requirements of Title 10, Code of Federal Regulations, Part 50, "Licensing of Production and Utilization Facilities," Appendix A, "General Design Criteria for Nuclear Power Plants," with respect to design against single failures in safety-related Light Water Reactor (LWR) fluid systems. Means of treating both active and passive failures are addressed for safety-related fluid systems following various initiating events. Current acceptable practice is used as a basis for these criteria.




American National Standard


Book Description

ANS This standard sets forth a series of design conditions and functional requirements for the design of fuel assemblies for light-water-cooled commercial power reactors. It includes specific requirements for design, as well as design criteria to ensure adequate fuel assembly performance. The standard establishes a procedure for performing an evaluation of the mechanical design of fuel assemblies.




American National Standard


Book Description

This standard sets forth minimum design, construction, and performance requirements, with due consideration for operation, of the liquid radioactive waste processing systems for light water reactor plants for design-basis inputs. It is applicable to routine operation, including design-basis fuel leakage and other design-basis occurrences.




American National Standard


Book Description

This standard presents the requirements of the Nuclear Safety Related Cooling Water Systems (NSRCWS) for Light Water Reactors (LWRs). It establishes nuclear safety requirements in the areas of design, materials, fabrication, placement and testing of systems. This standard is applicable to open and closed NSRCW systems. 58.9-1981 (R2020) provides criteria for the designer which interpret the requirements of Title 10, Code of Federal Regulations, Part 50, "Licensing of Production and Utilization Facilities," Appendix A, "General Design Criteria for Nuclear Power Plants," with respect to design against single failures in safety-related Light Water Reactor (LWR) fluid systems. Means of treating both active and passive failures are addressed for safety-related fluid systems following various initiating events. Current acceptable practice is used as a basis for these criteria.
