Sejvar, J; Dawson, P H

This report is associated with a comprehensive review of various chemical and mechanical decontamination methods being conducted by the Electric Power Research Institute. The primary goal of this review is to identify potential state-of-the-art methods for use in decontamination of fluid systems at the Three Mile Island Unit 2 (TMI-2) facility. The particular method addressed in this study is an abrasive grit/high-pressure water technique developed primarily for decontamination of steam generator channel heads. Included in the report is a description of the system and summaries of field experience to date. Also included are general guidelines, criteria, and pertinent parameters which must be considered in the application of this decontamination method as well as a general assessment of the applicability of this process to various components and systems.
