    16、ndard 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 treatment technology. In 2001, the

    17、 U.S. NuclearRegulatory Commission NRC! cited this standard for mobile treatment systemsin Rev. 2 of Regulatory Guide 1.143 RG 1.143!.

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 purpose of this standard to p

It isthe intent of this standard to identify a basis for establishing uniform practicesand minimum requirements for the design, fabrication, and operation of MRWPsystems as applied to

    20、nuclear facility operations e.g., power plants, institutions,and laboratories that generate wastes approved for disposal at 10 CFR 61 LLWdisposal sites!.

    22、 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.
