Decontamination techniques applicable to waste packages: Final report

Technical Report · Tue Mar 01 04:00:00 EST 1988

OSTI ID:6914866

This report presents an evaluation of methods for decontamination of reference waste canisters and waste containers. The potential use of chemical solvents, ultrasonics, liquid abrasive blasting, vibratory finishing, electropolishing, liquid honing, high-pressure steam/water spraying, and fixatives as decontamination techniques for outer waste package and canister surfaces is discussed. Either test results or available literature on these techniques were examined to assess applicability of the methods. Pertinent technical considerations for each method are presented and discussed. Electropolishing and liquid abrasive blasting are the processes recommended for remote decontamination of waste overpacks and canisters. These processes are recommended on the basis of a number of factors including the type of contaminants present; the geometric configurations and materials; the accessibility, size, and mass of the units; and the time available to perform the process. Representative process conceptual designs for electropolishing and liquid abrasive blasting are presented in this report. Major equipment items and process operations are discussed. Secondary waste treatment and disposal requirements are also briefly discussed. 16 refs., 7 figs., 4 tabs.
