Question 56: Would areas periodically patrolled, but not
constantly manned, be considered to fall within the
exception in 10 CFR 20.2202 (a) (2) and 20.2202 (b) (2) for
"locations where personnel are not normally stationed
during routine operations, such as hot-cells or process
enclosures?" For example, would these exceptions apply "if
a hallway or cubicle in the reactor auxiliary becomes an
airborne radioactivity area and auxiliary equipment
operators make their rounds periodically during their
shift?"
Answer: No, the exception would not apply to these areas
that are "periodically patrolled" or otherwise normally
accessible to personnel. However, for nuclear power plants
at power, primary containments are examples of "locations
where personnel are not normally stationed." (References:
10 CFR 20.2202 (a) (2), 10 CFR 20.2202 (b) (2))
