- (a) The disposal facility shall be designed to provide long term stability to the engineered structures of the disposal units.
(b) At a minimum, the stability requirements for the engineered structures for the different classes of waste shall be:
- (1) Class A radioactive waste—100 years.
- (2) Class B radioactive waste—300 years.
- (3) Class C radioactive waste—500 years.
- (4) Mixed waste—500 years.
- (c) If more than one class of waste is disposed of in the same disposal unit, the more stringent stability requirement shall be met.
- (d) Waste containers or modules shall be emplaced in the disposal unit in a manner that maintains physical integrity.
- (e) Waste containers or modules shall be designed and emplaced in the disposal unit in a manner that minimizes void space.
