7.5.3 Special Considerations During Decommissioning Activities

Before decommissioning or disposal of any facilities or equipment, an evaluation should be

performed to assess the potential holdup of fissionable material in any equipment. These types of

measurements may require the assistance of radiological control staff.

Some strippable coatings and surface-fixing films are effective neutron moderators. Nuclear

criticality safety specialists should be consulted when using these coatings to decontaminate surfaces

because criticality could be a concern, depending on the geometry of the removed coating when in the

disposal unit.
