Change Control Process
During the performance of decommissioning work, changes may be necessary to facility systems
or work plans that are not anticipated. In order to ensure that the safety basis is current,
adequate, and documented, it is important that a change control process be developed that
considers the significance of proposed changes and links to the USQ process to determine if
DOE approval of the change will be necessary.
Unanticipated changes or discovery of new information may also affect a condition, parameter,
or assumption that helped support the basis for downgrading a facility below hazard category 3.
Such changes should be subjected to a management of change process to evaluate potential
impact on the approved safety basis that supported a downgrade.  Violation of certain
assumptions and controls could invalidate the downgrade such as changes in radionuclide
material inventory, form of material, dispersibility (e.g., changes in container storage or energy
