This paper describes the operations of the Nuclear Safety Analysis Center. Established soon after an accident at the Three Mile Island nuclear power plant near Harrisburg, Pennsylvania, its efforts were initially directed towards a detailed analysis of the accident. Continuing functions include: (1) the analysis of generic nuclear safety issues, (2) serving as a repository for information resulting from the effort to restore the Three Mile Island plant, and (3) serving as a clearinghouse for technical information related to the safety and licensing of nuclear power plants. Two operation support systems are explained: the NOTEPAD computer-conferencing system, which provides information exchange among organizations concerned with nuclear plant operations; and a records management scheme built around a microfilmed document collection and a ZYTRON computer system for online information retrieval. A flow chart of the computer system, a sample database entry, and a list of subject-specific files available to NOTEPAD users are attached. (SW)
