The waste products of the no action alternative include:(1) existing calcine(2) calcine produced during the H4 calciner campaign, in which waste from Tank WM-188, an evaporated (3) calcine from calcination of blended and evaporated wastes from WM-185 and WM-187, presently (4) calcine of the remaining Sodium-Bearing Waste (SBW), including waste presently in WM-180, WM-(5) calcine from other wastes generated by ICCP facilities from 1996-2012. blend of waste previously stored in WM-189 and WM-183, is calcined stored in WM-189, plus calcine fiom the remaining wastes in WM-185 and WM-187 181, WM-184, and WM-186, and referred to as the "2008 composite" The volume of the existing calcine, as estimated by Dan Staiger, is 3809 m3.(I2)The volume of calcine produced from WM-188 has been calculated by Robert Rivard.3 Rivard calculates calcine volumes of 158 to 248 m3 for A1 to Na + K ratios of 3.2 to 6.3. I suggest that we use his calcine volume calculated at an A1 to Na + K ratio of 3.467, which is 166 m3. Rivard used a calcine density of 1.653 g/cm3 in his volume calculations. The waste which was previously in WM-189 was the last tank of "high level" waste.Blends of tank farm wastes fiom WM-185 (SBW) and WM-187 (a dilute-fluoride waste of secondand third cycle raffinates along with flushes and decon wastes) were evaporated in the High Level Liquid Waste Evaporator (HLLWE) in December of 1996 and January of 1997, and are being stored in W-189.4 The flowsheet for calcination of this waste has not been defined, nor has the completion of the evaporation of liquids in these two tanks. To estimate the calcine volume that will be produced from this waste, I assumed an A1 to Na + K mole ratio of 3.5, and used tank volumes and compositions from Reference 6 for WM-189 and WM-187, compositions of WM -185 from Reference 4 and a volume of WM-185 from a phone conversation with Clark Millet, May 22,1997. I assumed a heel of 14,000 gal remained in each of the tanks, and a calcine density of 1.2 g/cm3. Based on the above assumptions, the estimated calcine volume for WM-185/WM-187 tanks is 160 m3. The calcine chemistry in these calculations was based on O'Brien (Reference 55).Using the same method, calcine volumes fiom SBW were estimated based on a composite composition for WM-180, WM-181, WM-184, and WM-186, as given in Reference 7. The evaporated volume of this waste is estimated to be 790,000 gal or 3 million liters. The estimated calcine volume, assuming a calcine density of 1.2 g/cm3, is as follows:AV(Na+K) Mole Ratio Calcine Volume based on 500°C calcination, m3 1
