Revise laws relating to nuclear energy

This bill allows Montana to approve temporary storage facilities for spent nuclear fuel produced by in-state nuclear power plants, provided the facilities meet specific conditions. The key requirements are that the storage must occur on the same site as the operating power plant, receive a recommendation from the state's environmental quality department, and hold a construction and operation license from the federal Nuclear Regulatory Commission. The legislation also updates existing state law to clarify how the department must file recommendations with federal regulators and establishes a fee system to fund the department's participation in federal proceedings.
