e Docket No FEB 151972 ESVIROX Mr. John G. Miller Vice President F.C. Box 542 Reading, Pennsylvania 18101
Dear Mr. Miller:
In connection with the preparation of our Environmental Statement for Three Mila Island 1 & 2, we have established a program for estimating the type and quantities of nuclidas to be released annually from this facility. Personnel from the Oak Ridge National Laboratory are assisting us in this part of the environmental review. For this progr a we need basic data for a source term calculation and for a gaseous and liquid affluent analysis that specifically relate to Three Mile Island. Much of this information may already be in your application or Environmental Report, but to expedite the review we require a tabulation of this information as indicated in the enclosed list. Any data that is incon-sistent with information in your SAR or Environmental Report should be identified. Separate answers should be submitted for (1) the facility as presently designed, and (2) any projected design changes.
This information should be provided by February 18, 1972. If it is
~~
impossible to meet this schedule, please let us know. When we have this information for Three Mila Isisad and other facilities we may need to meet with you and representatives of other utilities at Oak Ridge to discuss the use of this information in our environmental analysis.
Sincerely.
Original signed By B, C, DeYoung R. C. DeYoung, Assistant Director for Pressurized Water Reactors Division of Reactor Licensing Enclosuret List of Questions ID.]
