The heavy water (D_2O) cooled and moderated pressurized water reactor MZFR with a thermal power of 200 MW will be dismantled step-by-step within the framework of sectional decommissioning licenses. The past decommissioning step (6"t"h sectional license) in general covered the removal of the primary systems and of all reactor support systems inside ...
When comparing the emissions, damages and external costs of combined and separate production, a system including a combined power and heat plant is balanced against systems with an equal coverage of energy demand, but with generation of power and heat in separate plants. Four case studies of supply with electricity and heat (two metropolitan areas,...
In the framework of the external verification of the fluiddynamic computer code ATHLET developed by GRS post-test analyses of three BETHSY experiments (integral tests at the facility BETHSY in Grenoble) were performed. In test BETHSY 6.2TC (medium break in the cold leg without high pressure injection) the most relevant physical phenomena: depressio...
For the turbomachines in all fields of application possibilities of further improvement are relatively small, but ecologically most important and with the multiplicity of cases of application and operational variants economically worthwhile. In order to exhaust this, it is necessary to penetrate even more deeply into the refinement of the current i...
