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.

Nuclear power in the Democratic and Republican party platforms—44 years ago
Tonight, Democratic presidential candidate Kamala Harris is expected to offer some policy details in a speech at the Democratic National Convention. With nuclear energy getting firm bipartisan support in Washington, D.C., it won’t come as a surprise if Harris backs nuclear power investments as part of her energy and climate policies.
But 11 campaigns and 44 years ago, in 1980, President Jimmy Carter and Republican presidential candidate Ronald Reagan were on the campaign trail in the first presidential election contest after the March 1979 accident at Three Mile Island. Democratic and Republican party operatives hashed out policy platforms that took stock of nuclear energy—and Nuclear News took note.

The severe-accident-free high-temperature gas-cooled reactor (SFHTR) is a prototype design for a next generation reactor. It is suitable for widespread deployment by virtue of its inherent safety features and very long refueling interval. Furthermore, its inherent safety features can be demonstrated by full-scale tests. Many of these features may be demonstrated in the High-Temperature Engineering Test Reactor (HTTR).The SFHTR is designed to have the probability of a severe accident at least two orders lower than existing systems. The fuel will not exceed its failure temperature even in the event of complete loss of coolant or complete withdrawal of two control rods. A unique configuration of burnable poisons allows a fuel cycle of 16 yr and a burnup exceeding 120 GWd/t. This feature promises very high availability and good economics.We have designed two SFHTR systems. The larger one, called the MSFHTR, has a 450- to 600-MW thermal capacity and is intended for the production of hydrogen and electricity. The smaller SFHTR (SSFHTR) is intended for remote areas, off the electrical grid, for simultaneous production of electricity and desalinated water. The SSFHTR can produce 23.5 MW(electric) plus 40 t/h of water with a net efficiency of 47%.The HTTR is capable of conducting full-scale simulation testing of key SFHTR design features in order to confirm and extend the designs and as a first step in convincing the public and the licensing authorities of the validity of demonstrable inherent safety. Design features of a 50-MW SFHTR focusing on the safety concept, safety evaluation, and core design are described. In addition, an HTTR-based test-and-development program for the SFHTR is presented.
