This paper presents the results of a pipe and vessel theoretical blowdown analysis in order to identify and assess rapid depressurization phenomena occurring during a Loss of Coolant Accident in a nuclear power plant. Calculations were performed in 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 and a computational model was built on the basis of available literature and implemented in MATLABr code. Finally, pipe depressurization results were compared to experimental results taken from the literature.
