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.

A high convertor pressure tube reactor is presented and analyzed from the standpoint of neutronics. High conversion and for some cases even breeding are obtained because of the hard neutron spectrum in a tight lattice reactor as well by reducing the parasitic absorptions through constant refueling. Eight different cases are analyzed with different fuels (232Th, 233U, 235U, 238U, and plutonium) and different coolants (H2O and D2O). The advantage of pressure tube reactors compared to pressure vessel reactors is demonstrated from the standpoint of the neutronics. This advantage is demonstrated by the improved fuel utilization associated with pressure tube reactors.
