Directs the Nuclear Regulatory Commission (NRC) to regulate the remediation of radioactive waste and nuclear materials at the Center according to prescribed guidelines.

Directs the Secretary to: ( 1) prepare any environmental impact statement for decommissioning or long-term stewardship of the Center in cooperation with the NRC and federal and state agencies; (2) assume exclusive use and possession of the entire Center; (3) take title to land or facilities at the Center that have not been approved by the NRC for release for unrestricted use; and (4) take title to radioactive and nonradioactive wastes and materials located at the Center.
