Upgrading auxiliary facility outleakage and combustion detection
Abstract
A new GAT preventive maintenance method, IMG-104, patterned after a similar successful procedure in use at the Oak Ridge Gaseous Diffusion Plant, was issued to improve the performance of the specially modified Pyrotronics HF/F2 detectors used in the X-342-A HF vaporizer bay and X-344-C HF storage facilities. Detector thermal protection was added/improved to increase cold weather sensitivity and reduce moisture absorption by the detectors' dibutylamine reagent. Other moisture problems previously experienced by the X-342-A feed vaporization facility UF6 outleakage/combustion unmodified detectors were eliminated following replacement of the twelve open steam chests with two totally enclosed autoclaves, and installation of a new outleakage/combustion detection system. Practical alternate methods of detecting UF6 outleakage and combustion by-products are discussed, as is substitution of the reagent used in the HF/F2 detectors; however, no changes were recommended.
