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)
