Abstract : This is the final report of the disposal of laboratory quantities of energetic materials. SRI examined the use of very hot water as a medium for safe and complete disposal of energetic materials. The temperatures Os the study were in the range of 200 - 350 deg C. 0ne of the tasks dealt with the hydrothermolytic destruction of a range of pure energetic materials and various energetic formulations. The program found that the pure materials PETN, HBNQ, TNAZ, and TNT, and the formulations Pentolyte, Comp B, Octol, AFX-644, AFX-931, and PBXN-109 were all converted to simple inorganic ions and CO2. Since AmP is water soluble, the ammonium nitrate work was conducted to develop some sense of the safe concentration limits in an aqueous system for hydrothermolytic destruction. The data obtained point to aqueous ammonium nitrate solutions that can be safely heated at concentrations up to about 12 wt %. AmP was found to be consumed at a rate apparently independent of starting pH. The products mirrored a widely ranging internal oxidation/reduction and included 40%, 15% and 15% of the starting nitrogen recovered respectively as N2, N2O and ammonium ion.
