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.

Detailed stracture of the magnetic field in the Large Helical Deveice (LHD) is studied numerically. The connection length of the divertor field line is found to be the order of several km or more. The possibility of the mirror-confined plasma in the chaotic field line region is shown. The divertor plasma model is proposed based on the long connection length and the existence of the mirror-confined plasma in the chaotic field line region. A new ICRF heating scheme (runaway ion heating scheme) for LHD is also proposed based on the existence of the mirror-confined plasma in the core plasma region.
