The purpose of ANS 19.1-2019 is to provide criteria for the use of nuclear data in reactor designcalculations. Thus, this standard identifies and describes the specifications for developing, preparing, anddocumenting nuclear data sets. The nuclear data sets considered are evaluated data sets, processedcontinuous data sets, and processed averaged data sets. These data sets enable the analysts to generatecross-section data, which are used as input in neutronics codes.
