- A comprehensive test program was prepared utilizing the LMFRE general outline as a point of departure. A minimum of one year was determined for the full-power demonstration run Work continued on the graphite development program, The concept of building the LMFRE with a full or partial blanket was considered as an alternate design. The nuclear specifications of the reference design LMFRE were calculated in spherical geometry, using the completed Spectral Code. The immediate and total temperature coefficients of the reference design were computed. The reactivity associated with various materials in the core and reflector test holes was estimated. Control rod calculations were revised. The set of fifteen differential equations representing the time behavior of the reactor power, temperature, and pressure after the introduction of reactivity was programmed and initial results obtained, Design studies indicated that on LMFRE critical experiment should be performed. A graphite core-reflector barrier reactor arrangement was selected as the LMFRE reference design. Work was accomplished on the reactor vessel, containment system, and control rods. Core thermal calculations were continued. Comparison of concretes for shielding was completed. Reactor start-up studies received consideration. Primary system components and materials were selected. The reactor building and facilities are described. Chemical considerations for the quarter were devoted to completing the LMFRE Phase I reference design for the chemical plant and associated research and test programs. The scope of chemical processing received extensive consideration throughout the conceptual design phase. Projects on chemistry, metallurgy, and other smaller laboratory test work are described.
