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.

High-purity, low-activity powder metallurgy aluminum alloys can be developed for use in a fusion reactor at 300 to 400°C using helium as a heat transfer medium. Hot water as a coolant may limit aluminum to 200°C. From a heat transfer point of view, based on the dual- or two-temperature design approach, commercial fusion reactor blanket designs appear to be feasible. To meet all of the blanket design requirements feasibility requires quantification of thermal hydraulics, materials, neutronics, and material responses. Also, radiation damage and lifetime analyses are key issues for design qualification. Based on tests performed to date, aluminum appears well suited for experimental fusion reactors operating at wall temperatures below 200°C.
