The following standard has been published: 1. ANSI/ANS-3.14-2021, Process for Infrastructure Aging Management and Life Extension ofNonreactor Nuclear Facilities (new standard). This standard addresses requirements for systematically evaluating structures, systems, and components to extend the life of nonreactor nuclear facilities. The standard provides a systematic process to determine the scope of the aging management/life extension program in terms of SSCs. For those SSCs, a process for evaluating remaining lifetime and determining the need for additional analysis, repairs, inspections, surveillance, testing, and spare part obsolescence will be developed. The following standard has been approved: 2. ANSI/ANS-2.15-2013 (R2021), Criteria for Modeling and Calculating Atmospheric Dispersion of Routine Radiological Releases from Nuclear Facilities (reaffirmation of ANSI/ ANS-2.15-2013 [R2017]). This standard establishes criteria for the use of meteorological data collected at nuclear facilities to evaluate the atmospheric effects on routine radioactive releases, inclusive of dilution, dispersion, plume rise, plume meander, aerodynamic effects of buildings, dry deposition, and wet deposition (e.g., precipitation scavenging).
