The Defense Waste Processing Facility (DWPF) melter off-gas flammability model for the current nitric- formic acid (NFA) flowsheet was revised in Revision 0 to reflect the upcoming reductant change from formic to glycolic acid. The necessary data for the model revision was obtained during Phase 2 of the Cold-cap Evaluation Furnace (CEF) test, which was completed on March 21, 2014 after 24 days of round-the-clock feeding and pouring, including a total downtime of ~20 hours due to equipment failures.
