The final safety analysis report (FSAR) for the Advanced Test Reactor (ATR) is presently being updated at the Idaho National Engineering Laboratory and will use the US Nuclear Regulatory Commission's FSAR format as a guide to provide a safety analysis comparable with that used throughout the commercial nuclear industry. In upgrading the FSAR, an updated reactor core physics analysis is performed on the unique serpentine core design. Unlike the two-dimensional (2D) partial core model used in the original FSAR, this new physics analysis uses both 2D and Three-dimensional (3D) PDQ full-core models employing the most recent cross-section data libraries. The 2D PDQ benchmark comparison provides a reliable validation for the ATR FSAR power distribution calculations. And the new full-core depletion analysis now provides a more detailed picture of changes in core composition, power distributions, and reactivity as a function of time.
