Progress report on research and development activities in 1982 of the Institut fuer Reaktorbauelemente
Description
In 1982 problems of the following subjects have been dealt with: - Thermohydraulic behaviour of core melts and pebble beds. - Fuel rod behaviour and effects of cooling channel blocking during loss-of-coolant incidents. - Hydraulics of pulsed screen bottom columns. - Evidence of incidents on the sodium-cooled fast breeder reactor. - Leakage-before-rupture behaviour of pipe lines. - Two-phase mass flow measuring methods. - Investigations on heat removal and stability of steel structures in the reactor vessel. - Thermo- and fluid dynamics of core elements with regular and irregular geometry. - Core emergency cooling for advanced pressurized water reactors. - Reliability of component parts in machine construction. - Investigations on fusion reactor components. - Fundamental investigations on natural convection.
