1n the early morning of November 22, 2016, an earthquake with a magnitude of 7.4 occurred near Fukushima Prefecture. Affected by this, the cooling device of unit 3 with 2544 fuel rods in the second Fukushima nuclear power plant stopped operation. Although the cooling function returned to normal after one and a half hours, the local people were still in a cold sweat after the news came out, and the atmosphere of “nuclear terror” still spread in Japanese society. So, what is Japan’s nuclear defense force
objectively speaking, Japan’s nuclear protection environment is still relatively fragile. Local nuclear power plants are large in size. 1n addition to nuclear reactors, power systems, water sources and other ancillary facilities also need to cover an area of at least 80000 square meters. The structure of nuclear power plant facilities is quite precise and fragile. As long as aerial bombs or conventional artillery fire on them at a low precision level, Even rockets launched by terrorists could paralyze nuclear power plants. Moreover, the physical structure of the nuclear power plant determines that it can only be built above the surface, which is an ideal target for the enemy
the 1970s and 1980s were a period of rapid development of Japan’s nuclear power plants. At this stage, Japan built 18 new nuclear power plants and 35 nuclear reactors (up to 51 in the 1990s). Since then, with some nuclear reactors abandoned, Japan still has 17 nuclear power plants and 44 nuclear reactors. 1t should be pointed out that these 17 nuclear power plants, densely distributed in the sea of Japan and the Pacific coast, are easy to be attacked
in March 2011, after the Fukushima nuclear power plant was hit by the tsunami caused by the earthquake and a large area of nuclear leakage occurred, the self defense forces began to strengthen the protection capability of the nuclear power plant. However, due to the late start, the scale and quality of the support of the relevant forces still lag behind the overall construction level of the self defense forces. Japan’s large number of nuclear power plants and high-density population distribution mean that in the event of a nuclear leak, the surrounding residents will suffer
the Ministry of foreign affairs of Japan has conducted a study on the possible damage to the nuclear power plant after being hit by air, and the results are “chilling”. Research shows that the nuclear leakage pollution caused by the attack on the nuclear power plant will cause great harm to the people in the surrounding areas. 1f the surrounding people are not transferred in advance, 18000 people will die and 41000 people will be poisoned; 1f the residents within a kilometer radius of the nuclear power plant are urgently transferred within one to five hours after the attack, 8200 people will still die and 33000 people will be acutely poisoned; 1n the long run, 24000 people will die of cancer, and the nuclear power plant within 87 km radius will no longer be suitable for human habitation< According to the Japanese news network, the Tokyo Fire Department disclosed the anti nuclear uniforms of firefighters participating in the water discharge and radiation monitoring of the Fukushima Daiichi nuclear power plant on the 21st. On the left side of the photo is the anti nuclear fire suit, and on the right side is the anti nuclear suit for nuclear radiation detection. The weight of each firefighter's anti nuclear clothing is about 16 kg
