Properties and environmental impact of ammonia scrubber discharge waste to the 216-A-36B crib

Technical Report · Fri Jan 01 04:00:00 EST 1988

OSTI ID:6848639

Review of process flowsheets for potentially reportable waste components was conducted at the Hanford Site. The review indicated that the ammonia scrubber distillate (ASD) appeared to contain reportable quantities of the Class C toxin ammonium hydroxide (NH/sub 4/OH). Sampling and analysis of the ASD waste stream confirmed that reportable levels of NH/sub 4/OH were present. The Plutonium-Uranium Extraction (PUREX) processes that generated the waste to the 216-A-36B Crib were discontinued. The responsible regulatory agencies were notified on August 31, 1987. This report provides characterization data for evaluating the effect on the environment of the discharge of the ASD waste stream. Data provided include the concentration and quantity of NH/sub 4/OH discharged per hour during the maximum five hours of discharge. The total quantity of NH/sub 4/OH discharged per 29-h headend cycles and the estimated total quantities of NH/sub 4/OH and NH/sub 4/F discharged from 1966 to 1971 and 1983 to 1987 are provided. Numbers and dates of decladding cycles, volumes of discharges, and frequency of discharge are provided and combined with the NH/sub 4/OH discharge quantity per cycle to develop the total NH/sub 4/OH discharge values. Inorganic and organic waste parameter values are provided for two sampling dates. Average ammonium fluoride (NH/sub 4/F) concentration of 10 hourly sampling of the 10-h decladding cycle are provided.
