FSEIS RAI Response 1994-08 TVA to NRC Letter.pdf Eva, here are TVAs verbal responses to our clarification questions on their RAI response submittal of May 26, 2011.
- 1. Referring to Enclosure 1, Table I; Enclosure 1, Attachment F; and Enclosure 1, Attachment G. The revised population by sector and radial distance around the WBN2 site estimate for 2040 was 50% greater than the same population estimate for 2040 provided in the application. However, the population estimates for the public water supplies downstream of WBN and the estimated recreational use of the Tennessee River downstream of WBM did not change. Should the public water supply and recreational use estimates have also been revised upward by 50%? If so, then what are the revised estimates? If a revision is not necessary, why not?
TVA response: The data they submitted on population for the year 2040 is correct.
- 2. Referring to Enclosure 1, Table 1, and item 5. The requested parameter was Fraction of milk-cow feed intake that is from pasture while on pasture. The response was 64 kg/d. The units imply that this is not a fraction. Explain how this value is to be used as a fraction of the total milk-cow feed intake.
TVA response: The fraction of milk-cow-feed intake that is from pasture while on pasture is 0.65.
- 3. Referring to Enclosure 1, Table II and Enclosure 1, Attachment F. The response in Enclosure 1, Table II states that boating and swimming was not considered at the recreation areas listed in Enclosure 1, Attachment F. Please explain why boating and swimming would not be considered at a recreation area.
TVA response: Their August 5, 1994 letter to the NRC explained why they do not consider boating and swimming in the dose calculations for Watts Bar. (the letter is attached to this e-mail)
- 4. Referring to Enclosure 1, Attachment E. What is the meaning of the Unplanned in the Nuclide row?
TVA response: TVA provided no answer on the meaning of Unplanned. They said it is based on NRCs NUREG-0017, so we should know what it means. However, an NRC staff member (Steve Schaffer or RES) in attendance explained it to them. It is the amount expected during operational occurrences and curie amount should be applied to the source term list of radionuclides released in liquid effluent.
