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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Effective energy cutoffs have been calculated on an IBM-7090 computer for cadmium, gadolinium, samarium, and boron filters as functions of filter geometry, the ratio of Maxwellian to epithermal flux (assumed to be 1/E), the lower energy limit of the 1/E flux, the energy corresponding to the Maxwellian most probable (modal) velocity, and filter thickness. The geometrical configurations were spherical (which on the assumptions made is equivalent to a beam flux case), cylindrical, and slab. By the use of two or three different filters (cadmium and gadolinium and perhaps samarium) it should be possible to detect resonances in the thermal to cutoff energy regions, in addition to measuring resonance integrals and thermal cross sections of unknown nuclides.
