    High Temperature Nuclear Power Plant GmbH as a Joint European Undertaking. As you may be aware, the THTR plant has been shut down and partially dismantled for years. In particular, the fuel elements have been removed from the power plant, so that the plant can no longer have any significance for the energy supply of the state of North Rhine-Westphalia (see question 3 in your letter). The...

    admits that this is 'obviously an unfortunate contract'. (...) Even later, the AVR got lost in the jungle of nuclear law. When the permit was finally available in 1994 and the tennis ball-sized fuel elements from the reactor were collected, it turned out that the FZJ had no permit to accept them. The federal government had to watch and pay for all of this. 'We have no legal...

    The approval notice contains a list of conditions including waste disposal, decommissioning concept and long-term treatment of highly contaminated waste and spent fuel that must be met before construction can begin. In our opinion these conditions are meaningless. (...) DEAT's press release dispenses with the fact that...

    in HTRs by investigating the direct application of high-temperature heat via a helium intermediate heat exchanger. Construction was completed in 1996 except for the spent fuel storage facility and an experimental hall. This was followed by functional tests and improvements were made to rod drives due to excessive heating of the upper concrete shielding...

    with emphasis on new type nuclear power plants. The US Senate has approved funding for industry to work with Russian scientists to develop a high-temperature reactor with spherical fuel elements. At the same time, efforts are being made there, in South Africa and in China, to exploit the possibilities and advantages of the pebble bed reactor. Japan is seriously investigating...

    After the Chernobyl disaster, the discussion about the HTR line took up a lot of space: "The possibility of military use of an HTR module was discussed. If lithium is added to the graphite of the fuel elements in excess of the unavoidable proportion, then targeted extraction of tritium can be achieved , a sought-after atomic bomb material can be achieved. The argumentation of the Soviet...

    Commonly used light water reactors have a whole range of economic and safety advantages: While conventional reactors have to be switched off regularly to replace the spent fuel, the high-temperature reactor can be operated continuously; the atomic fuel trapped in the graphite spheres (highly enriched uranium and/or thorium)...

    siedlungsnah errichtet werden sollen. Bezüglich der Freisetzungsmechanismen beim HTR ist es belanglos, ob Kernschmelzen möglich ist oder nicht, sondern es kommt darauf an, ob und wann die Brennelementteilchen (("coated particel") und die Brennelemente ihre Rückhaltewirkung verlieren. Genau diese Rückhaltewirkung lässt bei Temperaturen oberhalb von 1600o C nach und geht bei Temperaturen zwischen...

  12. 1986 - Lothar Hahn on the subject of safety at HTR

    Property of lesser importance. If rapid cooling is required, the high heat capacity is rather disadvantageous. Feature: High temperature resistance of the ceramic fuel elements and core structure materials, no core meltdown such as B. possible with light water reactors. Comment: The statement is correct, but misses the actual problem. It's not primarily about...
