U.S. Nuclear Regulatory Commission

Question 430: Question 373 concerns the minimum

requirements for height and access restrictions of barriers

used to prevent entry to locked high radiation areas (HRAs)

and very high radiation areas (VHRAs) at nuclear power

plants. Does this question and answer also apply to
