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.

An experimental program was set up at SCKCEN to determine the thermal neutron-induced fission cross section of curium isotopes. These transuranium nuclei are produced in nuclear reactors and are candidates for transmutation. This paper presents our 243Cm(n,f) measurement, yielding a cross-section value of (667 ± 26) b. A detailed analysis of the experimental results published by previous groups is performed, and the renormalized values are compared with our result. In general, a good agreement with old data is observed, questioning the values adopted by different nuclear data libraries.
