Assuming that "gas“ is needed, became 156 results found.
Fort St. Vrain, the original HTR didn't work either
found in the control rod cables, etc.." (2) The scientists from Darmstadt added: "Almost from the beginning, the FSV was not allowed to operate at more than 70% of full power due to gas fluctuations in the reactor core and problems with the cooling fan as well as uncertainties with the guaranteed residual heat removal performance . In addition, there was already a leak in the steam generator in 1981 and a whole...

The commitments are based on a law from the term of office of his predecessor George W. Bush - this allows government loans for projects by private energy companies provided they reduce greenhouse gas emissions. According to government figures, this fund currently has around $18 billion. Obama wants to triple it." The comment quoted by Deutsche Welle is particularly interesting:...
devices. RWE's two new coal-fired power plant blocks in Uentrop will not only emit 8,9 million tons of CO2 per year, but with an efficiency of 46 percent they are far behind modern gas and steam power plants. These new large power plants will be in operation for around 40 years and are hindering the expansion of renewable energies in this region for this period...
The history of the citizens' initiative in Hamm and its posters
To win over the population to our position. * With satirical leaflet campaigns, Hammer citizens were made aware of the dangers of THTR operations: At Christmas there are iodine tablets, gas masks and radiation protection suits. Nevertheless, the THTR went into operation. Sometimes for a few hours, then again for a few days. In between, standstills, shutdowns, problems, improvements,...
Entangled in the network of European uranium transports
and in 0,7 percent of cases connected to uranium 235 atoms. This type of uranium hexafluoride is called a “feed.” It is a crystalline white substance that becomes gaseous when heated to 56,5 degrees and can therefore be fed into a uranium enrichment plant (UAA). There the “feed” is separated: Enriched uranium hexafluoride contains at least 5 percent fluorine-uranium 235 molecules...

All original plans were given 'for free',” wrote the ND. No wonder, because even nuclear power plant supporters criticize the outdated technology of Atucha 2 and advocated converting it into a gas and steam power plant. Even today, Argentina does not want to fall behind Brazil. The big neighbor started building a uranium enrichment plant in 2006 and...

Nuclear action cannot be tolerated is now being contradicted in Dortmund. The newly founded citizens' initiative against nuclear facilities, Contratom, distributed leaflets on "Nagasaki Day" at the beginning of August and criticized the uranium enrichment plants in the USA, in Gronau in Westphalia, the planned one in Iran - and the involvement of local companies in the new construction of...

Control rods are inserted from above using the “pin in block” method and the cooling gas helium, known from THTR, flows through the cavity of 7 mm remaining between the rod and the hollow cylinder. The fuel elements do not have the shape of spheres, but of honeycomb-shaped hollow cylinders that are filled with "Coated Particles" (PAC beads, fuel particles), as we...
Reactor". In a review it says: "35 recognized engineers and scientists report in the English-language book on the operating results and the future prospects of the gas-cooled high-temperature reactor. Since the future of the high-temperature reactor in the Federal Republic is currently uncertain, the English edition of the book is intended to increase knowledge of this in the Federal Republic...
List of incidents at THTR - collected by Horst Blume
A malfunction was detected in the water-steam cycle. The defective controller was replaced immediately. 30.05. - June 02.06.1988, 12.06.1988: During a recurring test, a cooling water valve in the gas cleaning system did not close as planned. June XNUMX, XNUMX: The cooling water supply to the turbine was interrupted due to a defective electronic card in the control system of the dry cooling tower. Subsequently...

The underground salt dome contains not only radioactive waste from the GDR, but also, since 350, nuclear waste from West German nuclear research centers and the Würgassen nuclear power plant at a depth of around 1990 meters. In 1998 a storage freeze was imposed. As early as 2000, newspaper reports reported that several underground chambers were in danger of collapsing and that rocks weighing several thousand tons...

Water flowed at the expense of a dilapidated pipe system. Because the regulatory authority is now demanding investments and limiting returns to six percent per year, RWE is fleeing: there is more to be earned from gas and electricity. By purchasing Thames Water in 1999, RWE took over the world's largest water and wastewater facilities operated by a private company:...

Operating temperature for the fission of enriched uranium should not be around 300, but at least 950 degrees Celsius. This allows, for example, the noble gas helium to be heated in a parallel circuit, which first causes turbines to rotate to generate electricity. This heat is also sufficient to trigger additional chemical processes to produce the energy source hydrogen...

remains today"!! But we can rest assured. The following reactor systems were selected by the exclusive Generation IV Club in 2002 to be shortlisted in the future: VHTR: Gas-cooled ultra-high temperature reactor GFR: Gas-cooled fast reactor SCWR: Water-cooled Reactor with supercritical steam states LFR: Lead-cooled fast reactor MSR: Molten salt reactor...
contradiction. This connection is visualized in the graphic from the FZK newspaper (4, see below). Within the hydrogen “cake” there are not only coal, natural gas, biomass and solar heat as application forms. Nuclear power and nuclear heat have their own “district” and of course should not be missing. For the implementation of such energy research...

the environmental impact study submitted by the mine operators was evaluated in its own 24-page study (1). The institute found that the values of the radioactive gases radium and radon were underestimated by the operators by a factor of four. The German institute also criticized serious deficiencies, weak points and unresolved problems with regard to the...
