Prospects for the Use of Atmospheric Optical Communication at Nuclear and Fusion Facilities.

An analysis of the prospects for the use of atmospheric optical communication lines at industrial nuclear energy installations, including thermonuclear (fusion) reactors and energy facilities with on-site fuel reprocessing plants, was carried out. It is shown that modern atmospheric communication terminals make it possible to implement high-speed data exchange within the perimeter of energy complexes, as well as to provide an external backup communication channel protected by use of quantum key distribution technology. The absence of the need to lay special cables through limited-access areas to organize high-speed data transmission provides a significant advantage of atmospheric communication systems over any wired communication systems. A methodology is presented for assessing the feasibility of using atmospheric optical communications at nuclear facilities, and based on long-term meteorological observations in the area where ITER (International Thermonuclear Experimental Reactor) is located, graphs of the availability of atmospheric communications are constructed. The high prospects of using atmospheric laser communication at nuclear and fusion facilities are shown. [ABSTRACT FROM AUTHOR]
