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 neutronics characteristics of four possible driver fuels for the Fast Test Reactor (FTR) are compared. The fuels investigated are PuO2-SS and UO2-SS cermets and PuO2-238UO2 and UO2-238UO2 ceramics. Since a high flux is of paramount importance in a test reactor, low-inventory plutonium-fueled cores are found to be quite attractive for use in the FTR. For core volumes of approximately 600 liters, cermet fuels offer a higher neutron flux and a larger shutdown coefficient than oxide ceramic fuels. If the latter fuels are used, BeO could be added to enhance the Doppler coefficient.
