Nuclear Plant Analyzer development at the Idaho National Engineering Laboratory. [PWR; BWR]

The Nuclear Plant Analyzer (NPA) was developed for the United States Nuclear Regulatory Commission (USNRC) under the sponsorship of the USNRC's Office of Nuclear Regulatory Research. The NPA is the USNRC's chief computerized tool promoting fast and easy access to accurate computational tools, commercial plant design and behavior data, and experimental data obtained from the NRC's numerous test programs. The NPA development effort is a joint undertaking among the Idaho National Engineering Laboratory (INEL), the Los Alamos National Laboratory (LANL), and Technology Development of California (TDC). The INEL has responsibility for overall project direction, with LANL providing supporting development particularly related to the TRAC-PWR series of codes, and TDC providing development of a major component of the NPA, namely the Nuclear Plant Data Bank (NPDB). This paper addresses the INEL activities during FY 1984.
