WM2021 Conference, March 8 - 12, 2021, Phoenix, Arizona, USA 1 Waste Information Management System with 2020-21 Waste Streams – 21356 Himanshu Upadhyay * , Walter Quintero*, Santosh Joshi * , and Leonel Lagos * *Florida International University ABSTRACT The Waste Information Management System (WIMS) 2020-21 was updated to support the Department of Energy (DOE) accelerated cleanup program. The schedule compression required close coordination and a comprehensive review and prioritization of the barriers that impeded treatment and disposition of the waste streams at each site. Many issues related to waste treatment and disposal were potential critical path issues under the accelerated schedule. In order to facilitate accelerated cleanup initiatives, waste managers at DOE field sites and at DOE Headquarters in Washington, D.C. needed timely waste forecast and transportation information regarding the volumes and types of radioactive waste that would be generated by DOE sites over the next 35 years. Each local DOE site historically collected, organized, and displayed waste forecast information in separate and uniqu2018e systems. In order for interested parties to understand and view the complete DOE complex-wide picture, the radioactive waste and shipment information of each DOE site needed to be entered into a common application. The WIMS application was therefore created to serve as a common application to improve stakeholder comprehension and improve DOE radioactive waste treatment and disposal planning and scheduling. WIMS allows identification of total forecasted waste volumes, material classes, disposition sites, choke points, technological or regulatory barriers to treatment and disposal, along with forecasted waste transportation information by rail, truck and intermodal shipments. The Applied Research Center (ARC) at Florida International University (FIU) in Miami, Florida, developed and deployed the web-based forecast and transportation system and is responsible for updating the radioactive waste forecast and transportation data on a regular basis to ensure the long-term viability and value of this system INTRODUCTION The U.S. Government Accountability Office (GAO) published a report in 2005 that criticized the Department of Energy (DOE) for their lack of life-cycle cost analysis for low level waste (LLW) and mixed low level waste (MLLW) treatment and disposal [1]. Additionally, the National Governor’s Association and other stakeholder organizations called for a “national forum” and “formal integration” of DOE waste management plans. The DOE National Low Level Waste/Mixed Low Level Waste Disposition Strategy was issued as a draft advanced copy in 2006 and discussed DOE’s long-range strategy for managing and disposing LLW and MLLW [2]. The strategy discussed in the disposition strategy document is consistent with the DOE Strategic Plan [3], DOE Order 435.1 Radioactive Waste Management and the corresponding DOE Manual 435.1-1 Radioactive Waste Management Manual [4], which requires the integration of waste projections and life-cycle waste management planning into complex-wide decisions for LLW and MLLW. Accurate estimates of the quantity and type of present and future radioactive waste streams is critical to the development of tools to integrate the complex-wide management of LLW/MLLW treatment and disposal. To meet this need, DOE’s Office of Environmental Management (EM) was tasked with developing a new complex-wide LLW and MLLW database and subsequently worked with the Applied Research Center (ARC) at Florida International University (FIU) to develop, deploy, maintain, and update the system [5]. EM collects and validates the waste forecast data from the DOE sites and then provides the data to ARC at FIU for integration and deployment.
