ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

Why push materials to their breaking point?
Stephen Taller
We push materials to their breaking point for you.
Millions of Americans rely on nuclear energy. It provides 20 percent of electrical power in the United States—24 hours a day, 7 days a week, 365 days a year. To maintain this reliability, every material used in our reactors must work safely and efficiently.
I’m part of a team of world-class scientists, engineers, and technical professionals at Oak Ridge National Laboratory, testing and evaluating materials designed to thrive in one of the most complex environments on Earth. Nuclear reactors experience heavy stress loads, high temperatures, corrosive environments, and intense radiation fields. Combined, these forces can substantially impact the performance of cladding or other structural materials. We want to know where and under what conditions materials may fail to keep a reactor running safely and reliably.

The current-drive technique, using lower hybrid waves (LHWs) for radio-frequency heating, is of highest priority on EAST, and over 100 s steady-state long-pulse H-mode plasmas have been achieved recently. The suprathermal electrons driven by LHWs make the interpretation of electron cyclotron emission (ECE) spectrum complex. This paper presents the preliminary results of a synthetic diagnostic for interpreting the ECE measurement results in both ohmic and LHW-heated plasmas on EAST. The synthetic diagnostic is realized by using the simulation code SPECE. The agreement between the simulations and experimental results is fairly good for the ohmic cases. For the LHW case, the simulations don’t agree well enough with the measurements.
