North Korean nuclear weapons program
Japan's Foreign Minister Tarō Kōno and South Korean media announced on September 3, 2017 that North Korea had carried out another nuclear weapon test. This was indicated by measurements from various earthquake monitoring stations, which registered two tremors. The American USGS gave the strengths as 6,3 and 4,6. The first shock came from an explosion, the second, about 8 minutes later, from a collapse.
A few hours after these reports, North Korean state media announced that the country had tested a hydrogen bomb.
While the explosive power of the last tests from 2013 to 2016 was in the range of 10 to 25 kilotons of TNT equivalent, the explosive power of the explosion on September 3, 2017 is, according to initial estimates, in the range of a few hundred kilotons of TNT equivalent...

North Korean nuclear weapons program
On January 6, 2016, the government of North Korea announced that a successful test of a hydrogen bomb had been carried out for the first time. Seismic signals indicating a nuclear weapon explosion have been measured by Chinese and US earthquake monitors near the Punggye Ri nuclear weapons test site. However, the level of seismic activity expected from a hydrogen bomb does not match the measured values, since the explosive power of a hydrogen bomb is normally many times higher than that of a fission bomb. Rather, experts assume it is a fission bomb boosted using hydrogen. The People's Republic of China, which has often supported North Korean positions in the past, condemned the test in clear terms. At the request of the USA and Japan, the United Nations Security Council then convened an emergency meeting. On January 10, 2016, a U.S. B-52 bomber flew over South Korea, which was seen internationally as a reaffirmation of the U.S.-South Korean military alliance and a warning to North Korea not to escalate the situation too much...

The North Korean government refused until 1992 to allow full control by the Atomic Energy Agency (IAEA). During subsequent inspections, the IAEA found that there was a discrepancy between North Korea's reported amount of reprocessed plutonium and its own measurements. The IAEA suspected more plutonium was being reprocessed for a nuclear weapons program, totaling over 20 kilograms - enough for three small warheads. Tensions between the US and North Korea over nuclear weapons led to a crisis in the spring of 1994 that nearly culminated in war...

A missing component did not prevent backflow in the cooling lines of the storage pool for the fuel assemblies of Units 2 and 3. The storage basin could have become empty in an uncontrolled manner. Due to a malfunction, the cooling water injection line of the spent fuel pool could - instead of feeding water regularly - suck water from the pool, which would slowly empty it and lead to larger releases of radioactivity. There is usually a device to interrupt this suction process. In Cattenom it was found in January that this had never been attached to Blocks 2 and 3.

North Anna Nuclear Power Plant#Incidents
In August 2011, an unusual earthquake occurred along the northeast coast of the USA. The epicenter, with a magnitude of 5,8 Richter, was in Virginia, the same state as the nuclear power plant. The quake led to the failure of the external grid feed-in, which meant that both blocks had to be cooled down using emergency diesel generators (emergency power supply). After just 40 minutes of operation, one of the diesel engines failed due to damage to the cooler, which meant that the power required to operate the pumps had to be supplied by another diesel generator, the so-called emergency diesel. The day after the earthquake, the grid supply was restored to dissipate residual heat, but the blocks remained shut down for a longer period.
In December 2016, it became known that North Anna was also affected by the Creusot Forge scandal involving fake certificates. Parts of the lids of both reactor pressure vessels came from the affected Areva subsidiary.

On March 14, 2011, 73.000 liters of water, slightly contaminated with tritium, flowed into Lake Ontario because of a sealing problem at a pump. The operator and supervisory authority described the risks as "negligible".
In January 2012, according to the Sierra Club, the "broken" reactor 4 leaked contaminated water due to a leak ...

Chronology of the 2011 disaster in Japan
Due to the great Tōhoku earthquake on March 11, 2011 and the subsequent tsunami, all four reactor blocks at the Fukushima-Daini nuclear power plant (Fukushima 2) were shut down automatically.
On March 12, 2011, the temperature in the condensation chambers of units 1, 2 and 4 rose to over 100 ° C and the pressure relief systems stopped functioning. An evacuation zone of 10 kilometers radius was ordered for Fukushima II. The evacuation area of Fukushima II was therefore almost entirely within the 20 km evacuation zone for Fukushima I Daiichi. The temperature in the 3 reactors only fell below 15°C again on March 100th.
On April 18, 2011, the Japanese Nuclear Regulatory Agency (NISA) assessed the events at Fukushima-Daini as INES Level 3.

Fukushima, Japan
The three nuclear meltdowns at the Fukushima Daiichi nuclear power plant in March 2011 led to the largest radioactive contamination of the oceans in human history. This nuclear meltdown contaminated soil, air, food, and drinking water, and exposed the entire population of the region to elevated levels of radiation. It is still too early to assess the full extent of the health impacts of this disaster, but based on the amounts of radiation released, tens of thousands of additional cases of cancer and numerous other illnesses can be assumed...

The Fukushima disaster
End of the myth of safe nuclear power
The Fukushima disaster in March 2011 was the third disaster to occur after Mayak and Chernobyl. Entire areas of Japan were radioactively contaminated. To date, the Japanese government and the operator TEPCO do not have the situation under control. The destroyed reactors cannot be entered, and radioactive water contaminates groundwater and the Pacific Ocean.
This must be kept in mind in order to be able to assess the degree of irresponsibility of the Japanese government in its decision to bring nuclear power plants that were shut down after the GAU back online despite the resistance of the population.

Tricastin Nuclear Power Plant#Faults
On February 16, 2011, it was discovered that in more than half of the emergency diesel generators in blocks 3 and 4, some individual parts that had been replaced two years previously could fail prematurely if the diesel was running for a little longer. These quality defects were found to be the cause of a total failure of the diesel in a test at another nuclear power plant. If the external power grid and the reserve grid failed (emergency power), the power supply to dissipate the residual heat in the reactor core at Tricastin 3/4 would not have been guaranteed, and in the worst case scenario, this could have led to a core meltdown in both blocks...

Tricastin (France)
Old reactors on the Rhône from 1980/81
The Tricastin site has made headlines time and time again for a long list of mishaps and incidents, most notably in 2008.
The facility is located in the southern French department of Drôme on the Canal de Donzère-Mondragon next to the Rhône, south of Montélimar and north of Orange and Avignon. In Tricastin, four pressurized water reactors with an output of 955 MW each, which went into operation in 1980 and 1981, generate electricity. The facility is owned and operated by the French company Électricité de France (EDF). Manufacturer was Framatome (today AREVA).
In 2011, the French Institute for Nuclear Safety (IRSN) criticized the operators for not having given enough consideration to the fact that there are dangerous factories in the vicinity of the French nuclear power plants Gravelines, Saint-Alban and Tricastin, in which chemicals are produced, for example.
On February 11, 2015, the French nuclear regulatory authority ASN approved an extension of the operating life for the Tricastin-2 reactor by a further ten years, as did the same on June 9, 2015 for Tricastin-3 ...

Vermont Yankee Nuclear Power Plant
In February 2010, traces of 137Cs were found on the nuclear power plant site at levels three to XNUMX times higher, according to the Vermont government, than would be expected from the impact of nuclear weapons testing and the Chernobyl disaster. The operator Entergy then announced that it would remove the soil and dispose of it as nuclear waste.
On August 27, 2013, despite the extended license, the owner Entergy announced that the nuclear power plant was to be shut down in 2014 because continued operation was no longer economically viable. The reason for the Senate decision was a tritium leak in the plant's underground ...
