The Oak Ridge High Flux Isotope Reactor (HFIR). which began full-power operation in 1966. provides one of the highest steady-state neutron flux levels of any research reactor in the world. An ongoing vessel integrity analysis program to assess radiation-induced embrittlement of the HFIR reactor vessel requires the calculation of neutron and gamma displacements per atom (dpa). https://www.marcelovicente.com/product-category/detox-shampoo/
