Fukushima 50
Workers at the Fukushima Daiichi plant in Japan are risking their lives and staying at the nuclear power plant to prevent total destruction after the region was hit by natural disasters in 2011.
Nearly an hour after the quake, Fukushima Daiichi suffered a power outage, causing the power-operated cooling systems to fail. Although the workers initially tried to run the plant on car batteries, they eventually risked their lives to get closer to the reactors and worked virtually manually to prevent the plant from overheating.
