U.S. Nuclear Regulatory Commission
Question 17: Will QA Category 1 requirements discussed in Regulatory Guide 1.26 have to be changed due to offsite dose requirements of 0.5 rem being changed to 0.1 rem in the revised Part 20?
Answer: The revised Part 20 does not change the QA Category 1 requirements. The 0.5 rem bench-mark is for design considerations; therefore, it will likely remain the same.
