PR: American Nuclear Society welcomes Senate confirmation of Ted Garrish as the DOE’s nuclear energy secretary
Washington, D.C. — The American Nuclear Society (ANS) applauds the U.S. Senate's confirmation of Theodore “Ted” Garrish as Assistant Secretary for Nuclear Energy at the U.S. Department of Energy (DOE).
“On behalf of over 11,000 professionals in the fields of nuclear science and technology, the American Nuclear Society congratulates Mr. Garrish on being confirmed by the Senate to once again lead the DOE Office of Nuclear Energy,” said ANS President H.M. "Hash" Hashemian.

In this accuracy study, we have solved with the discrete S2, S4, and S8 approximations a monoenergetic half-space problem with a delta-function pencil of neutrons as a source and compared the values of four suitable integral quantities with the results of Monte Carlo calculations. The errors in the space-dependent integrated neutron flux are shown in several figures. Also, tests with different mesh resolutions of the iteration net and with different standard quadrature sets have been made.
