This report describes the simulation and analysis of solution level and density (L,D) in all key main process tanks in a large reprocessing plant. In addition, initial provisions were made to include temperature (T) data in the analysis at a later time. FacSim, a simulation program developed at Los Alamos, was used to generate simulated process operating data for the Rokkasho Reprocessing Plant (RRP) that is now under construction in Japan. Both normal facility operation and more than thirty abrupt diversion scenarios were modeled over 25-day periods of simulated operation beginning with clean startup of the facility. The simulation tracked uranium, plutonium (both +3 and +4 oxidation states), HNO{sub 3} diluent, and tributyl phosphate from the input accountability vessel to the plutonium output accountability vessel, with the status of each process vessel and many pipes recorded at intervals of approximately four minutes. These data were used to determine solution volume and density values in each process vessel as a function of time
