- 2. L. Waterfield, site-Environmental Branch, DAL QUESTION LIST FCE DCKZ POWER PSA1, DOCKET NO. 50-269 AND 50 270 site Plasse elaborate on the extent of the Duke Isad holdings within one mile of the plant.
Provide a drawing indicating the location of all areas within this distance which de not now belong to Duke, sad ladicate which ones are still being negotiatt.d.
Discuss the centrol of the Federal-owned land within this distance.
Hydrology Describe more fully the expected future use of Lake Keewee and
s shores, including the expected extent of building s===ar cottages, and the expected transient population due to this and all other activities. Are construction of any commercial or government-supported activities, such as metals, amusements, or boat doche and storage anticipated?
Give the distance and bearing from the reactor of the location of the water intake for the town of Seneca. What is the distance to the proposed intake point on Lake Hartwell for the city of Anderson and the towns of Clemson and Pendleton!
What is the relation of stream flows to travel times to these locations froa the sitaf How long can these municipalities contime normal operation without the use of these intakes?
What is the effective transit time and dilution factor between the plant liquid discharge canal and the intake canal for various flow conditions in th: rivers? What is the corresponding factor between the discharge canal and tailrace of the hydro-station for various stream flows, with and without the station in operation? What is the justification for discharging radio-active liquid waste directly off-site into the tailrace, rather that into Lake Kesweef How is this related to the minimum river flow rate of 30 efsf (Centiamed) emer >

O L Meteorofore In Appendix 23, please explain the discrepancy of the units in Table 7.
For instance, how can a calm with a duration of 12 to 17 hours1.967593e-4 days <br />0.00472 hours <br />2.810847e-5 weeks <br />6.4685e-6 months <br /> occur for only 2.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> per year? What is the average wind speed for Type F stability conditions, including the calms? Considering that this site is an area having one of the poorest dilution climates in the country, how can the use of a higher than usual wind speed for site evaluation be justified? Also, Why is the persistance of inversion coaditions less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />? Similar sites have shown such longer persistence of inverstens.
Please re-examine the assumed 30-day meteorology as compared to that presented for the yearly average. They appear to be the same, which is doubtful, and certainly not conservative. Re-examine the assumed 20% direction persistence in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in light of Weather Bureau data indicating the persistence at most sites is approximstely 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br />.
Acetdent Analysis Provide the additional constants required to calculate the reactor coolant activity from 1% failed fuel elementat release rate of noble gases, including how the half-life is accounted for1 boron removal rate; fsed-water addition rate, etc. Provide a technical definition of " equivalent curies of iodine-131." What mixing depth and deposition area in the lake are assumed in calculating the iodine intake from the reinout accident durin,g the first 5 or 10 days? For how long is the intake of water assumed in the dose calculation? Itow does the mixing depth vary with time af ter rainout?
What is the scope and type of sagles proposed for both the pre-and post-operational program of environmental monitoring?
