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.

In the GAMMA 10 tandem mirror device, an experimental plan of high power ECRH is now under way. As the first step, operation of existing gyrotrons for plug ECRH has been carried out at a power exceeding their nominal powers of 200 kW. In this step, the highest recorded value of [varphi]c for a hot ion mode plasma is 1.4 kV at Pplug = 240 kW. The effective temperature Teff of the end loss electrons as a scaling factor of the axial potential distribution has attained to 3 keV at a heating power of 260 kW and the potential difference between the plug to the end plate has exceeded 5 kV. Then, the potential range of the scaling between and Teff has been expanded. Use of a new gyrotron delivering much higher power is the second step. The first experimental campaign with this gyrotron has just started.
