You can see most of the nuclear plant facility when the camera pulls
back. It makes your realize how compact nuclear reactors are. This is
the world's nuclear largest nuc. facility. You are looking at 8.2 GWe
of reactors, the equivalent to 24,000 large scale wind turbines
(adjusting for actual versus nameplate). The site "covers 4.2
square-kilometers including land in Kashiwazaki city and Kariwa
village." That's 420 hectare; 1000 acres. Not much. See:
