Bill, The following was a handout during our public meeting on the review of Chapter 11/12 and the environmental review. The staff asked that you provide the information in this table that is applicable. This information is being requested as part of the effort to ensure consistency between the FSAR review and environmental review.

Information Required for Staff Analysis for Dose from Gaseous Effluents The staff will be performing dose assessment for dose to the public from gaseous effluents from Watts Bar Nuclear Unit 2 using the NRC developed GASPAR II computer code (Strenge et al.

1986) developed using the approach specified in Regulatory Guide 1.109 (NRC 1977). The following is a list of input values needed to run the computer code. Provide the data, the source of the data and any appropriate assumptions. Refer to RG 1.109 for any questions on the need for the parameter or more detail on what the parameter is.

Please provide answers to the following questions, as well as Tables 1-5.

a. Confirm that there are no milk goat or meat animals are present in the 5-mi radius.

b. Provide the direction and distance for the nearest residence, nearest garden, and nearest milk cow.

c. Confirm that releases are calculated as ground level releases

d. Provide nearest site boundary distances for the 16 cardinal compass directions

e. Provide the estimate of direct radiation doses from sources within the site for each of the 22.5-degree radial sectors centered on the 16 cardinal compass directions for radial distances of 2, 4, 6, 8, 10, 20, 40, 60, and 80 km (1.2, 2.5, 3.7, 5, 6.2, 12, 25, 27, and 50 mi) from the reactor.

f. Confirm that there are no unusual animals, plants, agricultural practices, game harvests, or food processing operations having the potential to contribute 10 percent or more to either individual or population doses in areas affected by liquid effluents, and food-processing operations involving large quantities of water.

g. Identify and provide a reference for direct radiation sources within or onsite out-of-plant as solid waste (e.g., independent fuel storage).

Provide the data, the source of the data and any appropriate assumptions. Refer to RG 1.109 for any questions on the need for the parameter or more detail on what the parameter is. Some supplementary information is provided in Regulatory Guide 1.113 (NRC 1977) to which the licensee is referred.

1. The staff compares their calculations against the applicants. Will TVA be revising the information in the TVA application or will the staffs comparison be against the 2008 application?
