Commercial nuclear facilities accumulate radiological and environmental controls program data and documents pursuant to company policy, regulatory, license, and technical specifications requirements. During and following the Three Mile Island Unit 2 (TMI-2) accident, many documents were generated that would not normally have been produced. To handle this increase in document volume, GPU Nuclear Corporation (GPU) designed and implemented an effective and efficient records management program at TMI-2. This records management program has proven invaluable, as GPU experienced litigation following the TMI-2 accident, including class actions alleging economic dislocation losses and radiation injury. The carefully planned and systematic generation of the proper radiological and environmental documentation and data in the regular course of business facilitates the admission of such records and data into evidence in radiation injury litigation. The status of postaccident litigation, the magnitude of document production, radiological and environmental controls records in litigation, radiological and environmental controls documentation, and lessons learned from previous radiation injury litigation cases are described.
