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...
Dimensions contain nuclear fuel or fissile materials. They are well known in the nuclear physics literature as PAC beads. Their structure is similar to the beads from which the fuel elements for the thorium high-temperature reactor in Hamm were made - these beads were manufactured on a large scale in Hanau. Alarmed by the “beads found in residential areas on the Elbe...
voted ;-) yes yes, I know what I'm talking about... so three cheers Horst "Stay as you are and..." PAC beads Top of page About the PAC beads, which are also found in the THTR fuel elements (see RB No.: 82) the newspaper "anti atom aktuell" reported in its issues 132/3 and 136 on three and seven pages respectively. Extensive research work was carried out...
THTR Circular No. 84 August 03
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...
The incident at the THTR in May 1986 in 'Spiegel'
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)...
List of incidents at THTR - collected by Horst Blume
Armed forces. For eight years there have been up to 80 arrivals per day in sunny weather. 06.04.1987/2/08.04.1987 The THTR has been switched off since March 25.04.1987nd. April XNUMX, XNUMX: Collection cans for fuel elements that could no longer be used were replaced. April XNUMX, XNUMX: Shutdown of the reactor. Checks on the pipes of the steam circuit. All welding wire areas on the small cables had to be checked...
1988 - Lothar Hahn on the subject of proliferation in pebble bed reactors
Due to the release mechanisms in HTR, it is irrelevant whether core meltdowns are possible or not, but what matters is whether and when the fuel elements ("coated particles") and the fuel elements lose their retaining effect. It is precisely this retaining effect that can be achieved at temperatures above 1600° C and is practically lost at temperatures between 2000 and 2500 o C. These are...
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...

The following was made clear in a report comprising several hundred pages: It is possible to divert uranium while the reactor is in operation because the tennis ball-sized, unmarked spherical fuel elements are particularly handy and can be exchanged unnoticed for dummy elements. The radioactive material for an atomic bomb can be produced within two months of operation. The...

helped, wasn't there another option that even Gandhi talked about if you don't want to cowardly let an injustice or a misfortune happen? Before loading the radioactive fuel elements, he inspected the construction site in order to carefully familiarize himself with a very specific idea. The gatehouse with a barrier, the expensive concrete wall, the fence on the cooling tower - was there...

The "forgotten" HTR Hanau scandal The decommissioned machines for the production of the fuel element balls can only be systems from the Hobeg company in the Hanau plutonium factory The sale must have taken place several years ago and there was no outcry in the media...
HTR is to be built as a Pebble Bed Modular Reactor (PBMR) in South Africa near Cape Town, this is one such point for our citizens' initiative. The Dortmund company Uhde is to build the fuel element factory in South Africa. There is already the very committed Böllstiftung and Earthlife Africa, with whom we work together. Before the South African Supreme Court, the...
