Mr. John F. Badalich Executive Director Minnesota Pollution Control Agency 459 Board of Realth Building University Campus Minneapolis, Minnesota 55440 Dear Mr. Badalicht Thank you for your letter of December 20, 1968. As regards the additional questions contained in your recent letter and its attachment, some further comments may be helpful.

The distance from dense population centers of nuclear power generating stations now under construction or in o ranges from a few milaa 'to to forty miles or more.peration None of then are located in metropolitan centers, but other reactors may be eventually. All of the plants, regardless of their location, are required by statute and the Commission's regulations to be designed, constructed and operated so as not to endanger the haalth and safety of the public. An extensive discussion of siting considerations is contained in the enclosed report of the Congressional Joint Committee on Atomic Esergy Esarings on the-Licensing and,Ragniation of Nuclear Reactors held in April and May 1967.

Approximately half of Mr. Godler's second list of questions relates to his concern about routine releases of radio-activity into the Mississippi River and into the air Amring operation of ths Monticello plant. giace a major part of the information transmitted with my earlier letter to you dated November 19, 1968 was devoted to this subject in response to about half of Mr. Gadler's first list of questions, I will not try to repeat what was in that trans-mittelishich should serve to answer the envira====r=1 9211250334 690217 PDR P

d Mr. John P. Badalich FEB 1 7 E3 release questions in the second list as well as the first.

In sumusary, such environmental releases are restricted under Part 20 of the causalssion's regulations to quantities which are not likely to result in exposures to members of the general public exceeding the limita recommended by the -

National Council on Radiation Protection and Measurements, -

the International commission on Radiological Protection and the Federal Radiation Council.

The remaining questions in Mr. Gadler's second list are directed to accident situations and the emergency procedures for notifying various authorities in the event that major releases of radioactivity into the environment should occur.

This was also discussed at some length in my previous transmittal. While it is not possible to rule out such accidents - on an absolute basis, the refeguards built into the plant design are so extensive as to make it extremely unlikely that any dangerous amount of radioactivity would be released offsite even in the event of credible accidents inside the contairmnent structure. Baergency procedures to cope with unlikely substantial radioactive releases offsite, including notification of appropriate public officials are required to be developed by all -licensees. prior to the start of nuclear- power plant operations. Such procedures' will be included in the final safety analysis report prepared by Northern 5tates Power Company-and reviewed for. adequacy by the staff and the Advisory Commaittee on Reactor Safeguards prior. to granting a license to operate . the Monticello plant.

This report will be a part of the public record, and a copy will be placed in the Commirision's Public Document Room when completed.

Records of the releases,will be required to be kept by the Monticello plant, and should be available to your Agency on request.

The remaining questions in,Nr. Gadler's second list are directed to accident situations and the energency procedures for notifying various authorities in the event that major releases of radioactivi,ty into the enviran==at should occur.

This was also discuss 94 at some length in my previous transmittal. While it is not possible to rule out such accidents on an hbeslute basis, the safeguards built into .

the plant design a,re so extensive as to makm it extremely unlikely that any' dangerous amount of radioactivity would ba released offeite even in the event of credible acci.ignes inside the conchinnent structure. Energency procedures to cope with unlikely substantial radioactive releases offsite, including not'ification of appropriate public- officials, are required to be developed by all licensees $rior to the start of n will be in/ clear power plant operations. Such procedures cluded in the final. safety analysis report prepared /by Northern States Power Company and reviewed for ade Reacto/quacybytheStaffandtheAdvisorycommitteeomSafeguards the Menticello plant.- This report will h a part of the Pubit'c record, and a copy will be placed in the Commission's Pub 1'ic Document Room when completed.
