Equipment Selection and Location


DOE-HDBK-1132-99
The secondary confinement system should be capable of collecting and
processing tritium leakage that may occur from tritium auxiliary systems.
Systems for fusion test facilities should, to the extent practical, minimize the
conversion of elemental tritium to releasable tritium oxide, which poses a
greater radiological hazard. Furthermore, to reduce radiation exposure due to
inhalation and adsorption of tritium through the skin, the designer should
consider using an independent compressed-air breathing air system to support
the air-supplied suits used by personnel while maintaining tritium systems and
equipment. Facility design should incorporate shielding where the potential for
substantial neutron or gamma radiation may exist. Area tritium monitors should
be considered.

DESIGN OF FACILITIES TO FACILITATE ULTIMATE DECONTAMINATION AND
DECOMMISSIONING.
Introduction . Facility design should include features that will facilitate

decontamination for future decommissioning, increase the potential for other
uses, or both. Design of the areas in a facility that may become contaminated
with radioactive or other hazardous materials under normal or abnormal
operating conditions should incorporate measures to simplify future
decontamination. For example, soil sampling could be considered prior to
construction so that a baseline is created, against which sampling results
during decommissioning can be compared.
Designs consistent with the program requirements of DOE 5820.2A,
RADIOACTIVE WASTE MANAGEMENT, should be developed during the
planning and design phases, based upon either a proposed decommissioning
method or a proposed method for conversion to other possible uses. Certain
design features can readily be implemented to reduce cross-contamination of
the facility and enhance the ease with which the facility can be
decontaminated. For example, air filters should be strategically placed in the
ventilation systems to control the spread of contamination into either the
exhaust or supply ducts, depending on conditions. Walls, ceilings, and floors
should be finished with easily cleaned materials; in some areas (e.g., hot cells
and process equipment rooms), metal liners may be preferred. Construction
