A Time and Motion simulation model was developed for the Waste Receiving and Processing (WRAP) Module 1 Facility which will be located at the Hanford site. The simulation model was developed using the WITNESS computer program licensed from AT T ISTEL. The model simulates the movement of 6,825 drums per year of transuranic (TRU) and low level waste (LLW) through the WRAP 1 Facility. In the WRAP 1 Facility, four main areas were modeled: Receiving, Non-Destructive Examination/Non-Destructive Assay (NDE/NDA), Waste Process and Shipping. Movement of waste drums through the plant is accomplished with forklifts, roller conveyors, two automated guided vehicles (AGV's), lift tables, jib cranes and pallet transfer carts. In-plant drum storage is provided by an automated storage and retrieval system (ASRS) for palletized drums in the Receiving/Shipping areas, a 12- drum storage carousel in the NDE/NDA area and a 24-drum storage carousel in the Waste Process area. The process simulation models use a color graphic display of plant operations to show drum (or pallet) movement throughout the plant. Actual speeds of vehicles, conveyors and forklifts are simulated in the model as well as machine cycle times, delay times, and stop times. Vehicle load and unload times, and acceleration and deceleration are included in the model. Distributions for the arrival of trucks delivering pallets or trucks leaving with waste drums or pallets are included in the model. Random numbers for distributions are assigned to determine the effect of variability on plant performance. The simulation program generates a full range of reports that allows users to determine the plant throughput under a wide variety of conditions. Typically a warm-up period is run to allow drums to complete travel through the system until steady steady-state'' operation is achieved . The model is then run at these steady-state conditions for several days, weeks or even years, depending on the complexity of the model.
