-Post Office Box 767 Chicago,-IL 60690 1

Gentlemen:

1 This letter'is to' inform you of a planned special ALARA appraisal at the LaSalle Nuclear Station during the week of April 22, 1990. The site team will be led by Mr. W. G. Snell of Region III and is expected to include four representatives from NRC Regions-I and III, two from NRC Headquarters and one from Brookhaven National Laboratory (BNL). One of the NRC Headquarters representatives is a Finnish citizen on temporary assignment with the NRC.

This individual will be an observer and will not work independently.- We will provide certification of radiation protection training so that site a

specific. training will be sufficient for unescorted access to radiologically controlled areas except possibly for the'Finnish citizen.

3 To assist the team in its preparation, we would appreciate that the information 1

identified in the attachments to this letter be provided to Region III by April.

j 10, 1990.

If-you determine there'is-a need, we can. travel to' LaSalle to pick up the information and discuss it with you at the same time.

The'above information was discussed in seperate' telephone conversations with Messrs.'G. Diederich and D. Hieggelke on February 26, _1990. We appreciate your cooperation in this matter.

If you have any questions, pleaseLeontact William i

Snell: at (708) 790-5513 or, Marty Schumacher at (708) 790-5514..

COMMENTS On a separate sheet, give the item nuniber your comment relates to and any

' additional information that will clarify your answer..

Examples:

15.

Magnetic filters were included in our plant design. They yicided only 50%

efficiency vs. 80% predicted, and as such are only marginally cost-effective.

20.

Engineering evaluation of this item conc 1uded that it was not cost-effective for our plant.

28.

Engineering evaluation of this item revealed it was cost effective assuming use occurred on critical path 25% of the time.
