An overview of present operations concerned with the management of Hanford-generated high-level radioactive wastes is presented. Interim storage, leak experience, costs, and program operations are discussed. (LK)

A synopsis is given of the detailed characterization of the existing environment at Hanford. The following aspects are covered: demography, land use, meteorology, geology, hydrology, and seismology. It is concluded that Hanford is one of the most extensively characterized nuclear sites. 16 figures. (DLC)

The practices which are currently used for handling radioactive waste are outlined. These include burial of solid waste, scrubbing of off gas streams, and routing liquid effluents (mostly cooling water) to open ponds where the water percolates to the water table. (LK)

Dielectrophoretic filtration experiments were conducted on glass, polyester, dacron, Teflon, wool, acrylic and polypropylene filter media. A polydispersed (sigma g = 2.0, ammd = 0.95 ..mu.. m) sodium chloride particle was used as a test aerosol. All materials exhibited significant increases in efficiency with increasing field strengths. Efficiencies of greater than 99 percent could be obtained from glass fiber mats using a 13 kV/cm electric field at 16.3 cm/s face velocity.

A conceptual drawing of the MX experiment is given. The central feature of the MX is a large superconducting magnet. The magnet parameters and conductor parameters are listed. The electrical and engineering design of the magnet is given.

An overview of the Hanford Long-Term High-Level Waste Management Program is presented. Four topics are discussed: first, the kinds and quantities of waste that will exist and are included in this program; second, how the plan is structured to solve this problem; third, the alternative waste management methods being considered; and fourth, the technology program that is in progress to carry out this plan.
