Reactor Controls Reliability and Maintenance at the Orr

Abstract

Early evaluation and study of the various criteria for the ORR clearly established the requirements for the fundamental safety and control instrumentation, and the instrumentation was well integrated into the design and construction of the plant. However, it was not designed for the optimum of maintenance convenience and minimum reactor down time in the event of instrument failure. This paper will attempt to describe the revisions and additions that have been made in the physical plant and maintenance which have resulted in a definite reduction of reactor down time due to instrument failure in both the reactor and in the experiments.
