RESUMPTION OF PLUTONIUM OPERATIONS IN BUILDINGS AT ROCKY FLATS.

SEC. 3133. RESUMPTION OF PLUTONIUM OPERATIONS IN BUILDINGS AT ROCKY FLATS. (a) Resumption of Plutonium Operations.—The Secretary of Energy may not resume plutonium operations in a plutonium operations building at the Rocky Flats Plant, Golden, Colorado, until the Defense Nuclear Facilities Safety Board determines, to the satisfaction of the Board, that the Secretary’s response to the Board’s recommendations numbered 90–2, 90–5, and 91–1 adequately protects public health and safety with respect to the operation of such building. (b) Resumption of Production of Plutonium Warhead Components.—The production of plutonium warhead components for any particular type of warhead may not be resumed at the Rocky Flats Plant until the later of— (1) April 1, 1992; or (2) 30 days after the date on which the Secretary of Defense and the Secretary of Energy certify to Congress that the production of that type of warhead is necessary in the interest of the national security of the United States. (c) Reports on Warhead Pit Reuse.—(1) The Defense Science Board shall prepare and submit to Congress a report on each type of warhead proposed to be produced at the Rocky Flats Plant. The report shall contain the following information: (A) Whether the reuse of existing plutonium pits in the production of that type of warhead is feasible. (B) If such reuse is feasible, the approximate cost and date on which it is feasible to begin the production of warheads of that type using such pits. (C) What modifications (if any) to the warhead, the weapon system for the warhead, or production facilities are necessary to permit the reuse of plutonium pits for the production of warheads of that type, and where (in the case of the warhead or the weapon system) such modifications would be made. 105 STAT. 1575 (D) Whether and how the performance of the warheads would be diminished or altered, if at all, by reason of the reuse of such pits for the production of those warheads. (E) The impact of pit reuse on worker exposure rates, and the amount of waste generated by pit reuse in comparison to new pit production. (F) Such other matters as the Defense Science Board finds appropriate. (2) In each instance that the Defense Science Board prepares a report under this subsection, the Board shall submit such report to the Secretary of Defense and the Secretary of Energy at least 30 days before submitting such report to Congress. (3) In each instance that the Defense Science Board submits a report under this subsection to Confess, the Secretary of Defense and the Secretary of Energy shall jointly submit a report to Congress containing comments on the Board's report and any related matters. (4) The Defense Science Board shall submit a report to Congress under this subsection with respect to warhead type W–88 not later than March 1, 1992. (d) Form of Reports.—Each report submitted pursuant to this section shall be submitted in an unclassified form. Classified information may be submitted in a classified appendix. (e) Definition.—For purposes of this section, the term “plutonium operations building” means the building numbered 371, 559, 707, 771, 776, 777, or 779 at the Rocky Flats Nuclear Weapons Plant, Golden, Colorado, or any other building at such Plant in which plutonium operations are conducted.
