new location of the proposed airport in the vicinity of the Black Fox Nuclear Power Station. The relocated position of the proposed airport brings it beyond about 6 miles from the Black Fox Station. This reduces significantly the aircraft impact risk with respect to the station.
However, with the information at hand, we are not able to conclude that the operation of the proposed airport would not pose an undue risk to the station.
Specifically, when an airport is located between 5 and 10 miles from a nuclear power station, we require a license applicant to submit a detai ed risk assess-ment if the projected annual number of operations exceeds 500 D}', where D is the distance (in miles) between the airport and the power plant. The projection is for the plant lifetime which is 40 years. Thus, for example, the proposed airport would exceed the above criterion when the annual number of operations reached 500 x 62 or 18,000 movements per year. Based on the statistics provided in the National Airport System Plan (1980-1989), it appears that this level of activity would be exceeded sometime within the next 40 years.
It may be possible to reduce the estimated annual number of operations with respect to general aviation..since it is our understanding that a significant portion of the operations involve touch-and-go movements used in pilot training. These movements would not be relevant to the safety of the Black Fox Station, since they would be confined to the inmediate vicinity of the airport. The overall effect of discounting touch-and-go movements would depend, in part, on the relative split between general aviation and larger aircraft (e.g. business jets) activity associated with the propcsed airport.
Thesizeofthelargestrunway(about6900 feet)sug{e.g.sthepossibilityof gest future airport expansion to service large aircraft carriers, military aircraft). This, coupled with its orientation (about 160 from a direction towards Black Fox Station) could be a source of concern requiring a detailed risk assessment and possible plant modification.

c; Mr. Robert A. Smith JUL 2 01981 In view of the above, we find that specific infomation with respect to projected airport operations (by type of novement, type of aircraft, and possibly with respect to runway approach usage) is needed in order to evaluate the potential effects of the proposed airport location on the Black Fox Nuclear Power Station.
if it is feasible for you.to provide this infomation to us, we believe that we could give you a definitive eveluation for your use.
In the c' cent that you nay have some questions, please feel free to contact Dr. K. Campe of our staff, who is the technical reviewer of aircraft hazards (telephone FTS 492-4882).
Sincerely.
