U.S. Nuclear Regulatory Commission

Question 384: Nuclear power plant licensees are required

to meet the criteria in 10 CFR 50 Appendix I and 40 CFR 190

with regards to maintaining doses to individual members of

the public ALARA. Related Regulatory Guides (e.g., 1.21,

1.109, and 4.1) describe programs which are acceptable to

the NRC staff to demonstrate compliance with 10 CFR 50

Appendix I and 40 CFR 190 criteria. Specific requirements

for monitoring, sampling, dose calculation and reporting

are included in each plant's Technical Specifications and

related Offsite Dose Calculation Manual. Does compliance

with plant Technical Specifications, applicable Regulatory

Guides, and the radiation standards in 40 CFR 190 fully

meet the requirements of 20.1301? The purpose in asking

this question is to obtain clarification that, although the

revised 10 CFR 20 introduces new dose limits for individual

members of the public and new effluent concentration values

in 10 CFR 20 Appendix B, the scope of monitoring, sampling,

dose calculation and reporting are not changed for nuclear

power plants by the revised 10 CFR 20 from the previously

applicable requirements and guidance.



Answer: Not necessarily. See the questions and answers

in sections 10 CFR 20.1301 and 10 CFR 20.1302. Generally,

for nuclear power plants, no major changes are needed in

"the scope of monitoring, sampling, dose calculation, and

reporting" that has been adequate for compliance with plant

Technical Specifications and 40 CFR 190, and for

conformance with applicable regulatory guides. However,

some relatively minor changes may be needed. For example,

at some plants, changes may be needed for demonstrating

compliance with the requirements of 10 CFR 20.1301 as they

apply in members of the public in controlled areas. (See

the answer to Question 104.) (References: 10 CFR 20.1301,

10 CFR 20.1302).
