Nuclear Regulatory Commission February 4, 2016 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is considering amending the NRC's Source Materials License No. STB-401 to allow the option to perform direct dose assessment of residual radioactivity in addition to using derived concentration guideline levels (DCGLs) to demonstrate compliance with the license termination criteria at the Mallinckrodt site in St. Louis, Missouri. The NRC staff is issuing an environmental assessment (EA) and finding of no significant impact (FONSI) associated with the proposed action.
