Assuming that "highly enriched“ is needed, became 32 results found.

there is radioactivity in it. In April 1995 at the latest, the radioactive components of the AMR were brought from Hamm to Ahaus in two castors. The special feature: They contained 3,9 kg of highly enriched uranium, almost 93 percent. This would make it possible to produce atomic bombs without any intermediate steps. On Wikipedia, the AMR is only mentioned in one sentence as “auxiliary reactor” (3). In...

"Radiological Dispersion Device" (RDD) or - more simply - from a "dirty bomb". It is necessary to make a clear distinction here. Atomic bombs are radioactive nuclear fission weapons made from highly enriched uranium or plutonium, which release an enormous explosive effect at high heat through a nuclear chain reaction, such as: B. the atomic bomb of Hiroshima. In contrast, a...
Tokaimura in Japan occurred on September 30, 1999, the worst nuclear accident in Japan to date. Two workers, who had not been informed by the operator JCO about the dangers of highly enriched uranium, had filled a uranium solution into a tank with steel buckets and by hand in too large a quantity and used "spoon-like devices" to mix it. To save time on production...
March 26, 2014 - THTR research in North Rhine-Westphalia continues!
Planning was underestimated" and the "contamination of individual components" could not or is not estimated. The atomic heritage shines ahead: 300.000 spherical fuel elements with highly enriched uranium. The Castor containers are above ground. The hall is an interim storage facility, currently without a permit. Rainer Moormann considers it all a “total debacle.” He criticizes the fact that...

what should happen to them. In addition to the option of storage on site or shipment to Ahaus, transport across the pond to the USA is also being discussed, as this is where the highly enriched uranium (HEU) for the THTR fuel elements came from (until 1977). The USA is interested in collecting the HEU, which was once so generously distributed, so that no...

already mentioned leaking tanks. This will increase remediation costs and delay the urgently needed remediation of the site. + Although there are nuclear balls that still contain highly enriched weapons-grade uranium from the USA, this by no means applies to all of them. In particular, the nuclear balls from the AVR no longer pose a threat in terms of weapon capability. Both...

is contaminated with high amounts of radioactive isotopes such as cesium-137 and strontium-90. In addition, there is a treacherous cargo slumbering inside: 198 spherical fuel elements, some with highly enriched uranium, which have become entangled and can no longer be removed. In two years, the core will be locked in a specially built interim storage facility on the research center site...

Something else happened: From 1967 to 1982, only 93% enriched uranium-235 was used in the THTR Jülich: “In the AVR, the working group has therefore been successively replacing highly enriched thorium-containing fuel elements with low-enriched fuel elements since 1982. In 1985 they accounted for 43% of the fuel elements contained in the reactor circuit” (3). It's pointless to talk about...

would have been if the reactor had had a higher temperature. In addition, the South African region could face another security problem: the highly enriched uranium required in the high-temperature reactor is weapons-grade. TAZ-Ruhr December 5, 12: The first model of the high-temperature reactor developed in collaboration with the Research Center Jülich (FZJ) has its...
1988 - Lothar Hahn on the subject of proliferation in pebble bed reactors
ask: At which stations through which the fuel passes is fissile material present in a form that is directly suitable for weapons, ie as plutonium (of any isotopic composition) or as highly enriched uranium 235? At which of these stations can fissile material be diverted for direct military use? At which of these stations can fissile material be produced in a form...

The possibility of using fissile material for weapons purposes has so far been kept out of the discussion about the THTR with the utmost care." Not only the highly enriched uranium, but also the low enriched uranium can in principle be diverted at various stations. The PBMR has a degree of enrichment of 8% is planned. At three percent...

expand the uranium separation work from the previous 1.800 t to 4.500 t. Then a total of around 35 nuclear power plants could be supplied beyond Germany and there would be hundreds of transports of highly enriched uranium every year - even more than before! While the Ahaus interim fuel storage facility (BEZ), only 17 kilometers from Gronau, is one of the most important crystallization points of the...
