This chapter summarizes the past activities at INEEL that generated this waste, current waste inventories, current waste management practices and facilities, and future p1ans. This background material defines the starting point for all treatment options, which are comprised of the technical process steps considered in greater detail in the chapters that follow.

The solid waste bins are partially buried stainless steel bins grouped inside concrete vaults (see Figure 1.1) , and they are designed to last 500 years (Palmer, 1998; Dirk, 19944; Schindler, 19743.5 Three to seven bins built adjacent to each other and within the same vault form a "bin set," and the piping from the calciner distributes calcine into each bin of a "bin set" (see Figure 1.2~.

This process creates additional HLW Trough mixing, and the possibility that this process may be continued caused the committee to regard SBW treatment as part of the task of this study. The underground tanks do not have secondary containment liners that meet current regulatory requirements of the Resource Conservation and Recovery Act (RCRA)

Four other tanks are surrounded by poured-in-place concrete vaults of square shape. Octagonal concrete vaults of "pillar and panel" construction surround the remaining 5 of the 11 steel tanks.

SNF planned for storage at the INEEL site and generated from other, off-site sources. As used in this report, these DOE SNF inventories are loosely labeled as "defense" in nature and are discussed only insofar as current DOE plans destine the HLW calcine and DOE SNF for co-disposal in the geologic repository under development for commercial SNF from nuclear power plants.

The DOE-EM program, created in 1989 to clean up the sites and wastes of the former nuclear weapons complex, routinely conducts EIS evaluations prior to the construction of major facilities. The DOE-EM is developing an EIS that addresses technical alternatives for the conversion of INEEL's HLW and SBW into waste forms suitable for off-site, out-of-state transport.

A succession of such steps, if properly designed and integrated into a treatment system, would produce final waste forms with radiological and material properties tailored to meet requirements imposed by long-term disposal conditions. For processing INEEL calcines and liquid waste into other forms, several technical options exist, as summarized briefly here.

The full context for this decision includes multiple criteria (e.g., worker risk, public safety, and environmental impact) and multiple and potentially competing objectives (e.g., responsible waste management consistent with INEEL's future plans and missions, local interest in pristine cleanup versus national interest in reducing total program cost)
