Dear Mr. O'Reilly:
SEQUOYAH NUCLEAR PLANT UNITS 1 AND 2 - SPECIAL REPORT - LAND USE SURVEY -

If you have any questions, please call Ken Parr at FTS 858-2685.
Very truly yours, TENNESSEE VALLEY AUTHORITY L. M. Mills, Manager Nuclear Licensing Enclosure cc:

ENCLOSURE LAND USE SURVEY AT SEQUOYAH NUCLEAR PIMT - 1983 Sequoyah Nuclear Plant Technical Specification 3.12.2 requires that:
With a land use census identifying a location (s) which yields a calculated dose or dose commitment greater than the values currently being calculated in Specification 4.11.2.3.1, in lieu of any other report required by Specification 6.9.1, prepare and submit to the Commission within 30 days, pursuant to Specification 6.9.2, a Special Report which identifies the new location (s).
and With a land use census identifying a location (s) which yields a calculated dose or dose commitment (via the same exposure pathway) 20 percent greater than at a location from which samples are currently being obtained in accordance with Specification 3.12.1, in lieu of any other report required by Specification 6.9.1, prepare and submit to the Commission within 30 days, pursuant to Specification 6.9.2, a Special Report which identifies the new location. The new location shall be added to the radiological environmental monitoring program within 30 days.
In response to the land use survey report received in October 1983, doses based on annual-average meteorology and design-basis source terms were calculated for air submersion, vegetable ingestion, and milk ingestion.
Locations producing the highest doses from air submersion and vegetable ingestion were not different from those currently used for making the routine calculations in accordance with Sequoyah Nuclear Plant Technical Specification 4.11.2.3.
As shown in the attached tabulation, milk producing animals were identified at three locations from which samples are not currently being obtained.
The owners of the animals were contacted concerning their willingness to provide a sample of the milk. All agreed to participate in the sampling program contingent upon the availability of milk and their ability to provide suf ficient quantities for analysis. The owner at location 5 indicated that his animal was not currently producing milk and would not until next spring.
Vegetation samples will be collected at that location until next spring when milk sampling will commence as milk is available. Milk sampling will be initiated immediately at locations 4 and 6 as the milk is available.
If the milk at any of the three locations become unavailable for sampling, vegetation samples will be. collected on a monthly basis.
