Summary

 
Object and purpose of research.The authors of this study suggest an barbotage-sprinkler emergency depressurization system for containment shells of marine nuclear reactors. The purpose of this analytical simulation is to confirm the efficiency of barbotage-sprinkler system in containment shell depressurization and to support selection of parameters for the emergency system at design stage
Subject matter and methods
This simulation is based on the physical & mathematical model developed by the authors to describe the dynamics of an emergency inside containment shell of nuclear reactor, and is performed in RAPAR calculation software for the parameters of environment inside the containment shell. Mathematically, this model is a numerically solvable system of non-linear differential and algebraic equations. Main results.
The results of this analytical simulation of a LOCA event have shown that emergency barbotage-sprinkler system can ensure required efficiecncy of depressurization for selected design of containment shell, and the methodological base developed by the authors, as well as calculation software for pressure and temperature inside containment shell can determine the parameters of this emergency system. Conclusion. Analytical simulation methods for the processes taking place inside containment shell of nuclear reactor are based on the physical & mathematical model developed by the authors and enable efficiency justification of emergency systems. This combined barbotage-sprinkler system can be used as emergency depressurization system for containment shells of marine nuclear reactors.
