The N-Reactor Department Research and Development Program for FY 1965, 1966, and later years is structured to achieve the following general goals. (1) Assurance of a high level of nuclear safety; (2) Assurance of achieving full plant life; (3) Reduction in operating costs for a given production rate; (4) Increase in production rate without proportionate increase in operating costs; (5) Savings in capital outlays necessary to achieve stated reductions in operating cost or increases in production; (6) Production of new products of value; (7) Savings in capital outlays or operating costs to achieve a given level of plant safety. The program is divided into three general categories; Reactor, Metallurgy, and Co-Product. The Reactor category is further divided into physics studies, thermal hydraulics studies, zircaloy process tube development, control, instrument and system analyses, chemistry, engineering research and development, gas, atmosphere studies, graphite studies, and nuclear safety research.
