Omissions? [7] Food grown in the area was banned from sale. Rising residual heat within each reactor’s core caused the fuel rods in reactors 1, 2, and 3 to overheat and partially melt down, leading at times to the release of radiation. By March 2017 all evacuation orders in the areas outside the difficult-to-return zone (which continued to sequester some 371 square km [about 143 square miles]) had been lifted. Germany’s exit . This page was last changed on 15 September 2020, at 13:47. [11][12] Plutonium contamination has been detected in the soil at two sites in the plant. The explosion, along with a fire touched off by rising temperatures in spent fuel rods stored in reactor 4, led to the release of higher levels of radiation from the plant. Months later, radiation levels remained high in the evacuation zone, and government officials remarked that the area might be uninhabitable for decades. [18][19][20][21][22] Platts, an energy news website, said that "the crisis at Japan's Fukushima nuclear plants has prompted leading energy-consuming countries to review the safety of their existing reactors and cast doubt on the speed and scale of planned expansions around the world".
