A webinar, and a new opportunity to take ANS’s CNP Exam
Applications are now open for the fall 2025 testing period for the American Nuclear Society’s Certified Nuclear Professional (CNP) exam. Applications are being accepted through October 14, and only three testing sessions are offered per year, so it is important to apply soon. The test will be administered from November 12 through December 16. To check eligibility and schedule your exam, click here.
In addition, taking place tomorrow (September 19) from 12:00 noon to 1:00 p.m. (CDT), ANS will host a new webinar, “How to Become a Certified Nuclear Professional.” More information is available below in this article.

The thermal scattering data for H in H2O are adjusted to better fit a series of criticality safety benchmarks using the Petten adjustment method for optimizing nuclear data. This method is based on the “Total Monte Carlo” approach developed for nuclear data uncertainty propagation to a large-scale system, together with a selection based on a global distance to specific criticality benchmarks. This paper demonstrates the possibility to improve the agreement with integral benchmarks by modifying the thermal scattering data. It is an additional step toward defining a globally adjusted nuclear data library with the Petten adjustment method, including thermal scattering data and nuclear data at higher energy.
