North Korea may be preparing for a new 280,000 nuclear test

According to the United States Johns Hopkins University Korean research site "latitude 38 degrees north latitude," 10, said the DPRK may be preparing for a new nuclear test.
According to the depth of excavation, experts speculate that the maximum equivalent of the nuclear test may reach 282,000 tons, if the news confirmed that the power of the nuclear test is 14 times the last time, that is equivalent to 100 kilometers away from the border at the same time Detonated 14 Hiroshima atomic bombs.
Does North Korea have the capacity to make such a nuclear equivalent?
Take a look at the amount of plutonium 239.
South Korea's Ministry of Defense issued on January 11, 2017, "2016 Defense White Paper" pointed out that the DPRK has a nuclear warhead can produce more than 50 kilograms of plutonium, the production of highly enriched uranium (HEU) and the ability to manufacture nuclear warheads and nuclear warhead miniaturization technology has reached a high Level.
Yonhap news agency quoted the White Paper on the 11th reported that the DPRK through several times in the Yongbyon nuclear facilities for spent fuel rods and then deal with more than 50 kilograms of plutonium. The 2008 Defense White Paper speculates that North Korea has more than 40 kilograms of plutonium, an increase of 10 kilograms after eight years. The manufacture of a nuclear weapon requires 4-6 kilograms of plutonium, thus speculating that North Korea can produce about 10 nuclear weapons.

Put the Nagasaki atomic bomb "fat", the use of plutonium charge.
The world's first put into combat plutonium bomb is codenamed "fat man" of the atomic bomb, when the World War II put into Japan Nagasaki, equivalent 20,000 tons, the total weight of 4545 kilograms, of which nuclear charge plutonium 239, 6.1 kg , Nuclear utilization rate of about 17%.
We have reason to believe that with the progress of technology, today's nuclear bombs can be used less than 72 years ago, nuclear charge, take the above said 4-6 kg lower limit, a nuclear bomb consumption of 4 kg of plutonium, explosive power still For the 20,000 tons equivalent, 280,000 tons of equivalent consumption of 56 kilograms of plutonium, count down the North Korean reserves of plutonium one-time consumption of light just to achieve this power.
Look at the number of uranium 235 stored.
South Korea military speculation, after 2010, North Korea's high-enriched uranium production capacity reached 40 kg. The manufacture of a uranium bomb requires 15 to 20 kilograms of highly enriched uranium, and the production of these highly enriched uranium requires a centrifugal separator of 750 to 1,000 units for one year in a row.
7 years, North Korea can produce 280 kilograms of highly enriched uranium, according to 15 kg of a nuclear bomb consumption, can produce 18 nuclear bombs.
Assuming that each nuclear bomb equivalent of 20,000 tons, a total of 360,000 tons of equivalent, uranium 235 can also meet the demand.
No matter what kind of charge, 280,000 tons of nuclear bombs will consume almost half of North Korea's nuclear material reserves, it can be said to put a super "artillery battle."
If North Korea really carry out the equivalent of 280,000 tons equivalent level of nuclear test, what will happen to the surrounding?
For the first time, the Chinese side of the border side of the residents have a greater impact.
1, resulting in a strong earthquake
Since the beginning of the nuclear test, the Chinese side of the residents will have a sense of shock, and with the increase in test equivalents, the earthquake became more intense.
January 6, 2016, North Korea test the first hydrogen bombs, seismic network determination of nuclear explosion site magnitude of 4.9. Hunchun people felt strong, the local people thought it was an earthquake, have to go out to avoid.
There are local residents said, "At that time people feel unstable," and the driver of the border in the driver told him that the more close to the border, that is, benevolent, Nanping feel more intense side.
September 9, 2016, the DPRK fifth nuclear test, equivalent to 20,000 tons.
Seismic network determination of nuclear explosion site magnitude of 5.0.
According to Yanbian interview in Jilin Province, CCTV reporter reported that Yanji City, shocked. People in the room can be clearly felt the furniture shaking.

September 9, 2010 8:35 am, Yanji Dongshan primary school, the school after the earthquake to organize students to hedge.
If the power directly increased by 14 times, it is difficult to imagine what will affect the local residents.
2, the risk of nuclear leakage
North Korea's nuclear tests were carried out at the nuclear test site at Fengxi County, Jizhou County, Hamgyong Road.
First, tunnel excavation, and then nuclear weapons and observation equipment placement, the DPRK will nuclear devices, radioactive observation equipment, seismic wave detector and other equipment into the test tunnel. In the connection cable and closed port stage, a variety of functional cables will be connected, the tunnel was soil, sand, gypsum, concrete, etc. closed up. Nuclear test preparation of the final stage of the signs of a variety of equipment in place, the staff import channel closed, the tunnel for the final landfill, and finally the explosion.
At present, the excavation depth of the nuclear test tunnel is not yet known.
However, from the US underground nuclear test situation, even if the nuclear bomb placed in the depth of underground kilometers, or a large number of nuclear radiation elements leaked.

Nevada underground nuclear test site

Even if the underground nuclear test to radioactivity fixed on the rock plate, to avoid the radioactive material spread to the atmosphere, but it can not guarantee not leak to the ground. In fact, if the depth of the tunnel is not enough, it will lead to radioactive gas through the backfill rock gap to the ground. For example, an underground nuclear test in the United States in 1970 caused radioactive gases to reach the territory of Canada. In 1971 in Sweden also detected the former Soviet Union underground nuclear test leaked radioactive material.
In any case, the DPRK's nuclear test, must not be taken lightly.
