The main purpose of the computational OECD/NEA PWR MSLB-Benchmark is the evaluation of the prediction capability of advanced code systems by means of a code-to-code comparison. The postulated MSLB-transient is characterized by a strong non-symmetrical core thermal behaviour due to the feedback between neutron kinetics and plant thermal hydraulics. ...
The main purpose of the computational OECD/NEA pressurized water reactor main steam line break (PWR MSLB) Benchmark is the evaluation of the prediction capability of advanced code systems by means of a code-to-code comparison. The postulated MSLB-transient is characterized by a strong non-symmetrical core thermal behaviour due to the feedback betwe...
In the framework of the code assessment and maintenance program (CAMP) of the US NRC the reflood model of the RELAP5 code is being validated at Forschungszentrum Karlsruhe (FZK) using data from the test PKL-IIB.5. The primaerkreislauf-(PKL) test IIB.5 simulates a double-ended break of the cold leg of a German 1300 MWe PWR with emphasis on the reflo...
Derzeitiger Stand der Forschung: Der Kohlenstaubdruckfeuerungs-Kombiprozess mit direkt befeuerter Gasturbine verspricht elektrische Wirkungsgrade ueber 50%. Die dazu notwendige Gasreinheit vor der Gasturbine ist bislang bei Temperaturen ueber 1000 C nicht erreichbar. Als ein Ansatz wird versucht, die notwendige Abscheidung von Asche und Alkaliverbi...
Within the scope of German reactor safety research the thermal-hydraulic behaviour in accumulators was investigated experimentally and analytically for transient injection. The paper includes the description of two test facilities used for separate effect experiments for the discharge flow of accumulators. Results derived from experiments at a glas...
