are still praised by interested circles in the professional world, in business and in politics for being "inherently safe": In contrast to light water reactors, for example, there is no risk of a core meltdown; Nuclear catastrophes are therefore not to be feared. Dr. In his investigations, Moormann came to the conclusion that...

again their hearts for supposedly inherently safe reactor lines where nothing bad can happen. Our THTR in Hamm. Or the small AVR experimental reactor in Jülich. If light water reactors have already fallen into disrepute around the world, why not rely on pebble bed reactors again and get state subsidies for them, as has been the case in the social democratic home state of North Rhine-Westphalia since...
The international INES rating scale and the list of nuclear power plant accidents
therefore 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, according to initial...

Article in the controversial magazine "MUT" was no exception, shows his long interview in the new right-wing "Junge Freiheit" (No. 28) in 2010 on the topic of "economic espionage". As the former President of the Federal Intelligence Service, who was well versed in all his skills, he knew exactly which newspaper he was dealing with. He will have chosen his medium carefully. In 2004 I wrote...

Fort St. Vrain, the original HTR didn't work either
Reactor Technology Network) today in 2010 cannot avoid admitting the problems in Fort St. Vrain in its presentation under "Experiences": "- Cavitation ("hollowing out", HB) of the water pumps = one year delay - Leaks in the heater Blower bearing = further delays - faults on (reserve) shut-off rods - bypass of hot helium and corrosion on shut-off rod drives -...

Accordingly, the useful temperature of the reactor would be reduced from 900o C to 720o C, which could result in a certain safety gain. However, similar to the German concepts, water intrusion would add a dangerous potential for accidents. Above all, the new concept offers no advantages over conventional reactors and is far too expensive. For the old PBMR concept...

Radioactivity in the groundwater With its 15 MW of electrical power, the AVR is a tiny experimental reactor. The THTR in Hamm, which is also prone to breakdowns, is Uentrop has twenty times higher performance. Which...
2008 - Moormann study - Inherent accidents and radioactivity emissions in the HTR line!
The operators of the THTR Hamm fought so vigorously against our demand for a nuclide register after it was shut down. An additional disaster would have been obvious and publicized! 8. Water leaks occurred. These must be excluded in the future using additional devices. "In the event of water intrusion, the penetration of liquid water into the globular cluster must also be...

by physics professor Schmitz-Feuerhake - formerly of the University of Bremen - nuclear facilities release more radioactivity than is officially stated. The operators would carry out continuous measurements on the exhaust air chimney and in the wastewater. "However, there are examples of unauthorized releases occurring. This is reflected, among other things, in the fact that children in the area...

The tritium accident in 1992, in which radioactive water seeped into the ground over a long period of time, shows that a lot can still happen even after a reactor has been officially shut down! One reason the KIKK study was created is...

The history of the citizens' initiative in Hamm and its posters
the planned construction of the THTR, but there was no longer-term citizens' initiative shortly before construction began. Only when it became known in 1975 that an additional light water reactor was to be built in Hamm did initial resistance arise. Although Hamm, with its 180.000 inhabitants, proudly called itself a big city, the social and cultural life was more like what you would expect...
Entangled in the network of European uranium transports
Its radioactive radiation is only weak, but with a uranium half-life of 4,5 billion years, once an area has been irradiated, it remains permanently contaminated. When in contact with water, uranium hexafluoride forms hydrofluoric acid (HF), a colorless gas with a pungent odor. Hydrofluoric acid is even more corrosive than hydrochloric acid and is very toxic. Since the skin absorbs the acid quickly, a...

Bariloche is the ultimate German colony in Argentina, the refuge of many Nazis. Here, together with the heads of the atomic center, they dreamed of a future plutonium and hydrogen bomb. Bariloche with its numerous German schools and clubs will be discussed at the end of the article. Why were Nazis in particular so interested in nuclear technology?...
