U.S. Nuclear Regulatory Commission

Question 67: This question concerns water approaches to

nuclear sites. Several sites for nuclear power plants

include portions of navigable lakes or rivers within their

licensed exclusion areas. Obviously, the utility does not

own these areas. Would such boundaries as defined in our

licenses qualify as restricted areas, controlled areas, or

unrestricted areas?

Answer: The licensee cannot limit access to navigable

lakes or rivers that the licensee does not own; therefore,

these bodies of water cannot be part of a restricted area

or controlled area and must be considered to be

unrestricted areas. However, for the dose calculations for

airborne effluents that are required by reactor technical

specifications and that are related to 10 CFR 50 Appendix

I, doses are not required to be calculated over such bodies

of water. (Reference: 10 CFR 20.1003)
