Licensee are obliged to follow regulation, in this specific topic to prepare
the optimization according the dose constraint fixed by Regulatory
Authority, so dose constraint should not be confused with the dose limit.
The difference between constraints and  a limit is in the action taken when
they are exceeded. Exceeding the constraint requires corrective actions to
prevent recurrence. Exceeding a limit also requires corrective actions to
prevent recurrence, but in this case, enforcement may also be taken.

 There are an interesting report prepared by the OECD Nuclear Energy Agency
and European Commission on Considerations on the Concept of Dose Constraint,
to those interested I can send a copy.
