Property studies of various alloy materials for fuel element cladding are described. Attempts to plate UO/sub 2/ pellets with Zr were performed. Corrosion studies on aluminum alloys in acid and in corrosion loops are reported. Results from the superheater thermal resistance test are summarized. Mechanical design and fission gas release of the boiler fuel elements are discussed. By a series of approximations based on existing information, the liquid level contour in the reactor vessel was calculated. Four flat tensile specimens of 2 wt.% B- stainless steel were tested at 500 and 1000 F. Wetter variations of the reference core were investigated for total coefficients, power distributions, and control rod worths. The effect of variations in the moderator density was determined for the reference boiler core. Lattice constants were determined for the low enriched superheater element concept. Burnup characteristics of the two- region core were calculated. Concentrations of N in various parts of the turbine buildin were calculated. A small 50 in./sup 2/ wound wiremetallic type filter was tested for filtration and backwashing characteristics. Calculations were performed to estimate the conditions and concentrations of the plant' off-gas'' under normal full power operation. Work on instrumentation is summarized.
