The Secretary, acting through the Administrator, shall submit to the congressional defense committees and the Nuclear Weapons Council the following:

(A) An independent cost estimate of the following: (i) Each nuclear weapon system undergoing life extension at the completion of phase 6.2A, relating to design definition and cost study. (ii) Each nuclear weapon system undergoing life extension at the completion of phase 6.3, relating to development engineering. (iii) Each nuclear weapon system undergoing life extension at the completion of phase 6.4, relating to production engineering, and before the initiation of phase 6.5, relating to first production. (iv) Each new nuclear facility within the nuclear security enterprise that is estimated to cost more than $500,000,000 before such facility achieves critical decision 1 and before such facility achieves critical decision 2 in the acquisition process. (v) Each nuclear weapons system undergoing a major alteration project (as defined in section 2753(a)(2) of this title).

(B) An independent cost review of each nuclear weapon system undergoing life extension at the completion of phase 6.2, relating to study of feasibility and down-select.

Each independent cost estimate and independent cost review under paragraph (1) shall include—

(A) whether the cost baseline or the budget estimate for the period covered by the future-years nuclear security program has changed, and the rationale for any such change; and

(B) any views of the Secretary or the Administrator regarding such estimate or review.

(3) The Administrator shall review and consider the results of any independent cost estimate or independent cost review of a nuclear weapon system or a nuclear facility, as the case may be, under this subsection before entering the next phase of the development process of such system or the acquisition process of such facility.

Except as otherwise specified in paragraph (1), each independent cost estimate or independent cost review of a nuclear weapon system or a nuclear facility under this subsection shall be submitted not later than 30 days after the date on which—

(A) in the case of a nuclear weapons system, such system completes a phase specified in such paragraph; or

(B) in the case of a nuclear facility, such facility achieves critical decision 1 as specified in subparagraph (A)(iv) of such paragraph.

(5) Each independent cost estimate or independent cost review submitted under this subsection shall be submitted in unclassified form, but may include a classified annex if necessary.

Upon the request of the Administrator, the Secretary of Defense, acting through the Director of Cost Assessment and Program Evaluation and in consultation with the Administrator, may conduct an independent cost assessment of any initiative or program of the Administration that is estimated to cost more than $500,000,000.
