(J) The development of alternative fuels and irradiation targets based on low-enriched uranium to convert research or other reactors fueled by highly-enriched uranium to such alternative fuels, as well as the conversion of reactors and irradiation targets employing highly-enriched uranium to employment of such alternative fuels and targets.

(K) Accelerated actions for the blend down of highly-enriched uranium to low-enriched uranium.

(L) The provision of assistance in the closure and decommissioning of sites identified as presenting risks of proliferation of proliferation-attractive fissile materials, radiological materials, and related equipment.

(M) Programs to— (i) assist in the placement of employees displaced as a result of actions pursuant to the program in enterprises not representing a proliferation threat; and (ii) convert sites identified as presenting risks of proliferation regarding proliferation-attractive fissile materials, radiological materials, and related equipment to purposes not representing a proliferation threat to the extent necessary to eliminate the proliferation threat.

(2) The Secretary of Energy shall, in coordination with the Secretary of State, carry out the program in consultation with, and with the assistance of, appropriate departments, agencies, and other entities of the United States Government.

(3) The Secretary of Energy shall, with the concurrence of the Secretary of State, carry out activities under the program in collaboration with such foreign governments, non-governmental organizations, and other international entities as the Secretary of Energy considers appropriate for the program.

Not later than January 1, 2006, the Secretary shall submit to Congress a classified final report on the program under subsection (b) that includes the following:

(1) Not later than March 15, 2005, the Secretary of Energy shall submit to Congress a classified interim report on the program under subsection (b).

Not later than January 1, 2006, the Secretary shall submit to Congress a classified final report on the program under subsection (b) that includes the following:

(A) A survey by the Secretary of the facilities and sites worldwide that contain proliferation-attractive fissile materials, radiological materials, or related equipment.

(B) A list of sites determined by the Secretary to be of the highest priority, taking into account risk of theft from such sites, for removal or security of proliferation-attractive fissile materials, radiological materials, or related equipment, organized by level of priority.

(C) A plan, including activities under the program under this section, for the removal, security, or both of proliferation-attractive fissile materials, radiological materials, or related equipment at vulnerable facilities and sites worldwide, including measurable milestones, metrics, and estimated costs for the implementation of the plan.

(3) A summary of each report under this subsection shall also be submitted to Congress in unclassified form.

Amounts authorized to be appropriated to the Secretary of Energy for defense nuclear nonproliferation activities shall be available for purposes of the program under this section.

Not later than October 31 of each year, the Secretary of Energy shall submit to the congressional defense committees a report on the receipt and use of amounts under this subsection during the preceding fiscal year. Each report for a fiscal year shall set forth—

(1) In general The Secretary of Energy may, with the concurrence of the Secretary of State, enter into one or more agreements with any person (including a foreign government, international organization, or multinational entity) that the Secretary of Energy considers appropriate under which the person contributes funds for purposes of the programs described in paragraph (2).

(2) Programs covered The programs described in this paragraph are any programs within the Office of Defense Nuclear Nonproliferation of the National Nuclear Security Administration.

(3) Retention and use of amounts Notwithstanding section 3302 of title 31, the Secretary of Energy may retain and use amounts contributed under an agreement under paragraph (1) for purposes of the programs described in paragraph (2).
