ASME Press
Publication date:


This chapter focuses on specific aspects that are the driving and controlling forces in hydraulic systems for nuclear power plants. It discusses how the ASME Boiler and Pressure Vessel Code requirements are implemented for Class 1, 2, and 3 nuclear pumps designed to meet the requirements of the Code. The Design Specification defines the applicable Code, the class of construction for the pump, and all operational requirements which define how the components function in their applications. The Owner’s Responsibilities for the system design play an important part in establishing the rules applicable to the Design Specification for each safety-related pump. The chapter provides a historical perspective for the Code rules, cross-referencing other Subsections of the Code. It is written to refer to and explain the requirements for pump Subarticles NB, NC, and ND-3400, and Articles NB, NC, and ND-7000 of the 2015 Edition of the Code. A Nonmandatory Appendix divides pump internal parts into various categories and sets up requirements for appropriate quality levels.
