A kidolgozandó feladat címe: System model development for safety analysis of VVER-1200 pressurized water reactors using the TRACE thermal-hydraulics code environment |
A téma rövid leírása, a megoldandó legfontosabb feladatok felsorolása: The VVER-1200 reactor is one of the leading Generation 3+ nuclear power plant technologies currently available on the market. In Europe several VVER-1200 type power plant units are being built or are being designed and licensed. The appropriate safety analysis of these reactors is crucial not only for the successful licensing but also for the safe long term operation of the power units. Important feature of the VVER-1200 technology is that active and passive safety systems are combined to cope with Design Basis Conditions and Design Extension Conditions and to fulfil the requirements set by the Nuclear Safety Codes. For the analysis of thermal-hydraulics processes within the power units different system codes can be applied. One of the leading, state-of-the-art simulation tools is TRACE (TRAC/RELAP Advanced Computational Engine), which is the flagship thermal-hydraulics analysis program of the US Nuclear Safety Regulatory. There is no system model available in TRACE for VVER-1200 reactors. The task of the PhD candidate is to develop, verify and validate a system model for VVER-1200 using TRACE, analyze DBC and DEC scenarios with special emphasis on small and large break loss of coolant accidents (SB/LB-LOCAs) and main steam line breaks. A further task is to evaluate the operation and effectiveness of active and passive safety systems of the VVER-1200 reactors. The PhD candidate would perform the following tasks:
