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 case of a drift-type disturbance, the systematic error of the period to be measured is reduced by the formation of first-order differences between the counts in successive time intervals. The influence of the correlation between the differences on the error of the period to be measured is studied; a connection is found between the parameters of the experiment to fulfill the condition that the correlation between the differences should be equal to zero; the precision limits of the period and reactivity measurements are obtained.
