Hydrogen generation during treatment of simulated high-level radioactive waste with formic acid
The Integrated Defense Waste Processing Facility (DWPF) Melter System (IDMS), operated by the Savannah River Laboratory, is a one-fifth scale pilot facility used in support of the start-up and operation of the Department of Energy`s DWPF. Five IDMS runs determined the effect of the presence of noble metals in HLW sludge on the H{sub 2} generation rate during the preparation of melter feed with formic acid. Overall, the results clearly showed that H{sub 2} generation in the DWPF SRAT could, at times, exceed the lower flammable limit of H{sub 2} in air (4 vol%), depending on such factors as offgas generation and air inleakage of the DWPF vessels. Therefore, the installation of a forced air purge system and H{sub 2} monitors were recommended to the DWPF to control the generation of H{sub 2} during melter feed preparation by fuel dilution.
