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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

Neutron activation cross sections between 15 and 40 MeV were measured by the activation method using a monoenergetic neutron field based on the 7Li(p,n)7Be reaction. Natural samples of carbon and cobalt, and separated isotope samples of 30Si, 47Ti, 48Ti, 52Cr and 58Ni were irradiated in the p-Li neutron fields generated by 20, 25, 30, 35, and 40 MeV protons. Neutron yields were determined from the amount of 7Be induced in the lithium target. The amount of 7Be was measured by observing the 0.478-MeV gamma rays of 7Be(T1/2 = 53.29 days) after the irradiation experiment. Cross sections of 12C(n,2n)11C, 30Si(n,np)29Al, 47Ti(n,np)46m+gSc, 48Ti(n,np)47Sc, 52Cr(n,2n)51Cr, 59Co(n,2n)58m+gCo, 59Co(n,3n)57Co, 59Co(n,4n)56Co, and 58Ni(n,2n)57Ni are reported.
