§ 236.314. Enhanced containment.
(a) The disposal facility shall include engineered structures. The engineered structures shall provide additional measures for isolation of waste from the environment. For the purpose of this section, the container by itself cannot satisfy requirements for enhanced containment.
(b) At a minimum, the engineered structures shall provide:
(1) Leak resistance for a minimum of 100 years, following the postclosure observation and maintenance period.
(2) Structural stability to the disposal units. Design goals for the material integrity and stability of the engineered structure shall be commensurate with the time periods specified in subsection (d).
(c) The disposal facility shall independently comply with performance objectives in § § 236.13 and 236.16 (relating to protection of the general population and environment from releases of radioactivity; and stability of the disposal site) without consideration of natural site features, through the active institutional control period.
(d) The design goal for the disposal facility to provide containment of the different classes of waste shall be for the following minimum time periods:
(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.
