ANS standard updated for determining meteorological information at nuclear facilities
Following approval in October from the American National Standards Institute, ANSI/ANS-3.11-2024, Determining Meteorological Information at Nuclear Facilities, was published in late November. This standard provides criteria for gathering, assembling, processing, storing, and disseminating meteorological information at commercial nuclear power plants, U.S. Department of Energy/National Nuclear Security Administration nuclear facilities, and other national or international nuclear facilities.

A semiempirical method allowing description and normalization of the prompt fission neutron spectrum (PFNS) is proposed. The method is based on the assumption that PFNS 235U(nth,f) and 252Cf(SF) have similar shapes. In the case of these two isotopes, the method works with accuracy of 1 to 2% in the energy range of 0.1 to 10 MeV.
