摘要：This paper presents results of pipe and vessel theoretical blowdown analysis in order to identify and assess basic rapid depressurization phenomena occurring during Loss of Coolant Accident e.g. in nuclear power plants. Therefore, calculations have been performed with conditions similar to those in a reactor pressure vessel. Due to critical two-phase flow occurrence, RELAP5 mod 3.3. and TRACE v 3.0 system codes were used for this purpose as well as a computational model built on the basis of available literature and implemented in the MATLAB® code. Finally, pipe depressurization results have been compared to experimental results taken from literature.
