Title: HIGH-TEMPERATURE MATERIALS AND REACTOR COMPONENT DEVELOPMENT PROGRAMS. VOLUME III. REACTOR COMPONENT DEVELOPMENT. First Annual Report

Abstract

Work in process on reactor component development during calendar year 1961 is reported. Eight specific development programs are reported including those on circulating ball reactivity control with capability of operating around sharp bends, static switching utilizing solid-state devices, capacitance temperature sensors based on the change in dielectric constant of alumina or beryllia vs. temperature change, high-temperature extension of conventional nuclear sensors (fission counters and d-c ionization chambers), nuclear sensors for monitoring and controlling hightemperature, high-performance reactors, high- temperature fasteners involving stress relaxation of Inconel bolts and nuts up to 600 deg C, fasteners for remote maintenance, and Monte Carlo program for nuclear analysis of complex reactor and shield systems. Results indicate the positive feasibility of moving small magnetic rods with a length-todiameter ratio of approximately two, by means of a linear electrical induction-type drive; moving balls of magnetic material does not appear feasible. In other work, a temperature sensor, basing its sensing ability on the change in dielectric of alumina with temperature, was successfully operated up to 1000 deg F, and two fission counters demonstrated satisfactory operation to 1500 deg F for times in excess of 150 hours each. Program packages for the present version of the three major Montemore » Carlo digital computer programs and necessary auxiliary programs were compiled and delivered to the twelve requesting installations.
