Lifting lugs should be considered as a part of equipment designs to better
facilitate equipment removal both during maintenance and decommissioning.
The ease with which a remotely operated device could be used in the rigging
effort should also be considered.
Building Layout (to Facilitate Decontamination and Decommissioning) .
Facility designs should limit the spread of contamination and simplify periodic
decontamination and ultimate facility decommissioning and disposal or reuse,
especially where radioactive or other hazardous materials will be used or will
result from facility operations.
Areas for work with like radioactive or other hazardous materials should be
located together to simplify solutions to problems of air supply and exhaust,
waste disposal, decontamination, and cross-contamination. However, design
criteria should specify minimum potential for cross-contamination between
radiological and hazardous materials. In addition, areas where radioactive
materials are used should be designed for ease of decontamination during
building use and for decommissioning at the end of the building' life cycle.
Use of modular, separable confinements for radioactive and/or hazardous
materials should be considered to preclude contamination of structural
components or nonprocess support equipment and to allow for easy removal.
The size and arrangement of corridors should accommodate movement of
equipment for initial installation, facility operations, future replacement or
removal, and ultimate decontamination and decommissioning (D&D) of the
facility, including required equipment accessibility during decontamination.
Access to facilitate decontamination should be provided in areas most likely to
become contaminated, such as crawl spaces, piping tunnels, and hatches into
Air exhaust filters, either roughing or HEPA, should be located as near to
individual enclosures or equipment as reasonably possible to minimize long
runs of internally contaminated ductwork.
