Draft EIS
^ y Cooling System Chemical Decontamination at Dresden Nuc or Station Unit No. 1 The Draft Environmental Impact Statement, NUREG-0686, hay 1980, related to the Primary Cooling System Chenical Decontamination at Dresden Nuclear Power Station, Unit No.1, Commonwealth Edison Company has been reviewed by the Bureau of Radiological Health, Food and Drug Administra-tion. We have the following comments to offer.
1.
Our assessment of the proposed decontamination operation indicates that the planning, system testing, and training of personnel provides adequate assurance that the occupational radiai.lon exposure will be maintained As Low As Reasonably Achievable (ALARA).
2.
The Atomic Industrial Formum in February 1980 published a document titled "An Assessment of Engineering Techniques for Reducing Occupational Radiation Exposure at Operating Nuclear Power Plants." Pages 23-24 contains a discussion of chemical decontamination as a means of reducing the primary source term.
It states in connection with the estimated exposure reduction that, "the long term effectiveness of decontamination has not j
been established. Operating experience indicates that activity build-up of corrosion products show an increasing trend through at 1 east fit 3 years of operation. Consequently, a system decontamination would not be effective over the long term and repeat decontamination would probably be required at least every five years to gain substantial reduction."
It would be appropriate for the DEIS to contain a discussion of the need for repeat decontamination operations.
It is noted that the staff analysis of future occupational exposure savings is based on a five year period of operation.
3.
As an editorial comment the last sentence of the first paragraph under section 4.2.3, Radioactive Waste Disposal should read "... principal radionuclides to decay to hsignificant levels".

'4 The environmental impacts of postulated accidents are discussed
-in section 4.3.
Even though accidental releases of radio-activity has a low probability of occurrence, it would be appropriate to expand this section to include a statement that coordination with the State of Illinois has taken place.
This is -particularly important at this time in view of the public and State agencies concerns about potential exposure to low levels of radiation.
5.
The statement does not contain any information on the monitoring program at the Dresden Nuclear Power Station.
It would be helpful to expand the statement by adding a section on environmental monitoring which could specify the adequacy of the existing program to monitor any accidental releases.
Thank you for the opportunity of reviewing this draft statement.
