Design criteria for decommissioning of nuclear fuel reprocessing plants - approved 1975

This standard provides criteria for designers of nuclear fuel reprocessing facilities to guide them in enabling these facilities to meet the requirements of Federal Regulations governing shutdown and decommissioning. Title 10 Code of Federal Regulations, Chapter 1, Part 50, Appendix F, states in part that a design objective for fuel reprocessing plants shall be to facilitate decontamination and removal of all significant radioactive wastes at the time the facility is permanently decommissioned. Included in the scope of this Standard are the following considerations: (1) protection from radiation hazards to personnel and the environment during and after decommissioning; (2) decontamination of plant structures and process equipment; (3) dismantling or isolation of the facilities; and (4) disposal of contaminated materials. When the owner has deactivated or shut down one process facility but continues to operate on the same site or builds another operating plant on the same site, this deactivation of the facility, even if it involves abandonment in place, is not decommissioning in the context of this Standard. Deactivation can be partial or can involve complete shutdown of process operation
