Fundamental to the effective management of radioactive wastes is thedesign, construction, and operation of radioactive waste
13、processing systems. Thisstandard was originally issued in 1993 in response to interest in the use ofmobile radioactive waste processing systems that could be transported fromfacility to facility, retained in service at a facility for an extended period of timeor quickly replaced by alternate treatme
14、nt technology. In 2001, the U.S. NuclearRegulatory Commission NRC! cited this standard for mobile treatment systemsin Rev. 2 of Regulatory Guide 1.143 RG 1.143!. The NRC also granted designrelief in Rev. 2 of RG 1.143 when it allowed Power Piping ANSI0ASME B31.1!versus Process Piping ANSI0ASME B31.3
15、! to be used for radioactive wastesystems.Unfortunately, this standard failed to be reaffirmed in 2003. This standard isbeing reissued to incorporate the design relief granted by the NRC in 2001 andto service continued operation at nuclear facilities and new nuclear facilityconstruction.It is the pu
16、rpose of this standard to provide requirements for the design and op-eration of the mobile low-level radioactive waste processingMRWP! system. It isthe intent of this standard to identify a basis for establishing uniform practicesand minimum requirements for the design, fabrication, and operation of
17、 MRWPsystems as applied to nuclear facility operations e.g., power plants, institutions,and laboratories that generate wastes approved for disposal at 10 CFR 61 LLWdisposal sites!. This standards scope does not address systems used to processwaste from nuclear facilities that potentially contain fis
18、sile material in sufficientquantities to require controls to avoid criticality; i.e., ANSI0ANS-40.37-2009 re-quirements do not address wastes containing quantities of fissile or long-lived ra-dionuclides that are classified as high-level or transuranic radioactive waste atypicalof NRC-licensed comme
19、rcial facilities and beyond the scope of 10 CFR 61. Systemsapplicable to non-low-level waste that use this standard might have to meet ad-ditional requirements beyond the scope of this standard. This standard addressesthe technical practices and requirements necessary for radioactive waste process-i
