scope:

This standard¹⁾ sets forth the design, construction, and performance requirements for a solid radioactive waste processing system for light-water-cooled reactor plants. For the purposes of this standard, the solid radioactive waste processing system begins at the interface with the liquid radioactive waste processing system boundary and at the inlets to the spent resin, filter sludge, evaporator and/or membrane concentrate, and phase separator tanks. In addition, this standard pertains to dry active waste (DAW), mixed waste, and other solid radioactive waste forms that are generated as part of the operation and maintenance of lightwater- cooled reactor plants. The system includes facilities for temporary (up to 30 days of anticipated normal waste generation) on-site storage of packaged waste but terminates at the point of loading the filled drums and other containers on a vehicle. The solid radioactive waste processing system is not a safety-class system as defined by ANS-51.1-1983 (R1988) (withdrawn) [1]²⁾ or ANS-52.1-1983 (R1988) (withdrawn) [2].

¹⁾ The current standard, ANSI/ANS-55.1-2021, is hereinafter referred to as "this standard."
