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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Penn State and Westinghouse make eVinci microreactor plan official
Penn State and Westinghouse Electric Company are working together to site a new research reactor on Penn State’s University Park, Pa., campus: Westinghouse’s eVinci, a HALEU TRISO-fueled sodium heat-pipe reactor. Penn State has announced that it submitted a letter of intent to host and operate an eVinci reactor to the Nuclear Regulatory Commission on February 28 and plans to engage with the NRC on specific siting decisions. Penn State already boasts the Breazeale reactor, which began operating in 1955 as the first licensed research reactor at a university in the United States. At 70, the Breazeale reactor is still in operation.

This study was undertaken to evaluate Zircaloy-2 clad titanium-base dispersions containing enriched boron or enriched titanium diboride as possible control materials. Results of corrosion tests of the nonirradiated dispersions indicated that cladding with a corrosion resistant material was necessary. Roll bonding Zircaloy-2 cladding to titanium-base dispersions was shown to be feasible through a study of the integrity, corrosion resistance, and bend properties of the clad dispersions. Clad separation and excessive swelling were noted in the samples of clad titanium-base dispersions containing 5 w/o enriched boron which were irradiated for long exposures. The clad 34 w/o enriched titanium diboride dispersion irradiated to nearly the same exposures showed no visual evidence of clad cracking or excessive swelling. Metallographic examination after irradiation, which was confined to the 5 w/o enriched boron dispersion, revealed internal cracking and bond line damage with the severity of damage increasing with increasing irradiation exposure.
