Issues in Prioritization for Remedial Action at ORNL (Oak Ridge National Laboratory)

摘要

A primary goal of the remedial action program at Oak Ridge National Laboratory is to effect closure of existing sites of contamination by radioactive material so that public health will be protected now and in the future. An important aspect of planning for remedial action is assessing programmatic priorities. Two types of remedial actions can be the imposition of institutional controls over contaminated sites and cleanup and closure of sites to an extent sufficient to ensure protection of public health in the absence of institutional controls. Current efforts in prioritizing remedial action sites at ORNL have focused principally on identifying broad issues that must be addressed in developing remedial action strategies. This paper briefly discusses the regulatory and institutional issues of importance to the development of remedial action strategies; a preliminary assessment of radiation doses associated with current levels of radioactivity at contaminated sites and their environs, which can provide useful information on the need for and most appropriate types of remedial action; and data and modeling needs for prioritization and their relationship to different options for program planning. 7 refs.
