TECHNOLOGY UPDATE which must be scrapped and replaced entirely when it corrodes, the thin-walled insert is replaceable. Sensors located in the pressuretransfer fluid detect any breach of the insert. The NitRem process and the dual-shell reactor technologies have been licensed to a Little Rock, Ark. company, ThermoEnergy Corp., which is marketing them for nitrogen contamination cleanup of industrial and municipal waste streams. —KELLYN S.

Novel reactor destroys nitro-wastes Results of full-scale tests of the "NitRem" noncatalytic hydrothermal process, which destroys nitrogencontaining wastes, have been compiled by scientists at the Pacific Northwest National Laboratory (PNNL) in Richland, Wash. Completed last summer at the Radford Army Ammunition Plant in Radford, Va., the novel process demonstrated a dinitrotoluene destruction efficiency of 99.996%, reducing contaminant levels from 120,000 ppb to
