Question 14: Are Design Basis Accident criteria (doses)
changed by the revised Part 20?
Answer: No, only those conforming changes included in the
Federal Register notice will be effective when the revised
Part 20 is implemented. Old dose criteria used for Design
Basis Accident will retain their original definitions
unless they are specifically changed in a licensing action.
