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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

TOUR REGISTRATION DEADLINE HAS PASSED
Idaho National Laboratory (INL), the nation’s nuclear energy laboratory, will be hosting a tour of some of its key “Site” locations, including the National Historic Landmark Experimental Breeder Reactor-I Atomic Museum, the Advanced Test Reactor and the Materials and Fuels Complex.
Experimental Breeder Reactor-I was the first reactor built at what is now Idaho National Laboratory. It was also the first reactor in the world to prove the principle in 1951 that electricity could be supplied from atomic energy. It is therefore known as the world’s first nuclear power plant and is now a museum and registered National Historic Landmark.
The Advanced Test Reactor, a third-generation test reactor, has held the first position on the International Atomic Energy Agency’s list of the most powerful research and test reactors since it first powered up in 1967. In just months, ATR can rapidly age materials duplicating years or even decades of neutron damage an experiment would see in a commercial reactor. This capability makes ATR the national and international materials and fuels irradiation facility of choice.
The Materials and Fuels Complex is the bustling “metropolis” of INL’s 890-square mile site. MFC is a vital component of U.S. nuclear research and development efforts, with capabilities ranging from post-irradiation examination of new fuel types to producing radioisotope power systems that power spacecraft such as the Perseverance Rover on Mars. It is home to the largest inert hot cell in the world as well as two of INL's operating test reactors, the Transient Test Reactor, and the Neutron Radiography Reactor.
