Assuming that "release“ is needed, became 123 results found.
May 18, 2016 - News about the THTR incident -
do not attract attention. Dr. Daoud, as representative of the main commissioning company HRB (Hochtemperatur Reaktorbau GmbH) and head of start-up operations, acted on his own authority, which has criminal relevance in view of the release of radioactive substances. The radioactively contaminated bullet fragment was intentionally blown out into the surrounding area, thereby exposing the population to great danger...
also those with 1280 degrees, but this only proves that this temperature has at least been reached. + The report also shows that there was an increased release of radioactivity in the reactor core, particularly between 1974 and 1976. Quote: “It is incomprehensible to the expert group that after evaluating the third series of monitor spheres from 1986 to 1988, no further...

that would have caused the reactor to run away within a very short space of time - as happened in Chernobyl. The AVR's low security barriers would have been breached. The release of the radioactive dust in the reactor vessel, which was caused by the poor retention of the fuel balls, would have led to considerable contamination of the environment....

(Formation of explosive gas mixtures, corrosion and destruction of fuel elements, increase in nuclear reactivity). Leaks in the reactor vessel that: - lead directly to the release of large quantities of radioactive dust accumulated in the reactors into the environment, since pebble bed reactors cannot have a tight containment like conventional reactors (e.g. Fukushima). -...

of the spent nuclear fuel pool - instead of feeding water in regularly - would suck water out of 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 discovered in January that this had never been installed in blocks 2 and 3....
2008 - Moormann study - Inherent accidents and radioactivity emissions in the HTR line!
This means that it is partially mobile in pressure relief accidents, which must be taken into account in safety assessments of future reactors." 3. Unacceptably high core temperatures are the cause of high releases. "This revealed that the contamination of the AVR cooling circuit is not, as previously assumed, primarily caused by inadequate fuel element qualities but was through...

of the German Childhood Cancer Register in Mainz. On December 10, 2007, this committee unanimously stated in its statement on the study results that radioactive releases from German nuclear power plants cannot be ruled out as the cause of the increased cases of childhood cancer. According to physics professor Schmitz-Feuerhake - formerly...

is celebrated for the future, this is an alarming sign. In 1986, there was no catastrophe in the THTR prototype in Hamm, but there was a momentous accident with the release of radioactivity, which put a - today we have to say only a temporary - end to this nuclear power variant. Just 15 years ago, no one would have bet a single cent on this reactor line...

future should happen. A rapid demolition will put the population at additional risk because the radioactivity has not yet decayed sufficiently and the dismantling of the reactor would result in radioactive releases and countless transports of nuclear waste. Additional transport routes would put even more people at risk. A safe final storage facility is also not yet in sight. In the reactor...

to be responsible. As is the case in the Elbmarsch. The highest rate of childhood leukemia in the world was found in the area around the GKSS (Society for Nuclear Energy Utilization in Shipbuilding and Shipping), where there was also a release of PAC beads: 17 cases of childhood leukemia in a very sparsely populated area! They employ numerous...

a lot to do with Hamm and the THTR: During a nuclear experiment in the GKSS there was an explosion on September 12, 1986, during which there was probably a release of small radioactive spheres containing uranium, thorium and plutonium . They have a diameter of less than half a millimeter. Exactly these with the eye hardly...
Entangled in the network of European uranium transports
Reaction of the uranium hexafluoride with the humidity would begin. This reaction is not violent, so no excess pressure will build up in the container. To stop the chemical reaction and the release of hydrofluoric acid, it is sufficient to prevent further air from entering the container. This requires a seal with appropriate bandages made of PVC film, which are secured with plastic adhesives...

abroad. As a third key component of its nuclear policy, the federal government changed the Radiation Protection Ordinance in 2001. The new regulation allows the release of radioactive waste into the environment in unlimited quantities. According to her, a large part of the rubble from demolished nuclear reactors will end up in the nearest landfill in the future (these are nice prospects for the THTR...

Failure of the tritium measuring channel in the activity monitoring of the nacelle exhaust air. July 19.07.1992, 13.11.1992: Malfunctions in the V-belt drive of a supply air fan in the nuclear ventilation system. November 1992, 1993: Release of an exhaust fan for the reactor hall. * December XNUMX to February XNUMX: “Tritium accident”: Even after its decommissioning, a long-lasting accident occurred in the THTR with a release...
1988 - Lothar Hahn on the subject of proliferation in pebble bed reactors
High-temperature reactors could not be achieved anyway. In general, it is then claimed that at HTR no accident sequence is possible, which would result in radioactive releases that would require disaster prevention measures outside the facility. Such an argument must be rejected as false and dubious because - consciously or unconsciously? - to the...

and the residual heat removal (and ultimately also the retention of fission products) relies on active safety devices and/or handles if serious accidents and significant releases of the radioactive inventory (approximately the same size in relation to the output of the light water reactor) are to be prevented. As evidence for the claim of supposed inherent safety...

(final storage advance payment). The “incident” you mentioned in 1986 was not an incident but a “category N reportable incident”. The repeatedly reported releases and the resulting radioactive emissions amounted to 1/5.000th of the natural and civilizational pollution, were below the approved daily and half-yearly values and...

It can be ensured that the temperatures of the core structures remain below 1500o C throughout the entire accident. This means that the inclusion of the fuel is not endangered by the release of the decay output."
