With the initiation of the LAMPRE Program Quarterly Report the opportunity is taken to review the objectives of the program as well as to summarize its present status. The program can be conveniently divided into two separate but related phases. The first is concerned with the design and construction of the first reactor experiment, called LAMPRE I. The second involves problems of specific interest for LAMPRE I as well as to the general class of molten plutonium fueled reactors. A general description. core parameters, reactor and plant configarations, and general status of LAMPRE I are given. Current progress is reported in terms of capsule certification tests, sodium system, fuel element storage, and LCX III measurements. The research and development work in support of the LAMPRE program includes Na loop (heat exchanger) studies. fuel alloy development, container alloy development, core concept studies, nuclear physics calculations, mechanical fabrication and welding development, corrosion studies, liquid fuel handling and circulating experiments, fission gas studies, mobile blanket develepment, and fuel processing experiments. A fairly complete account of tbe various lines of development at the present time is contained. (W.D.M.)
