The research deals with boron dilution that might occur during some transient conditions in PWR, VVER-1000. A boron diluted coolant plug may cause a neutron flux excursion. The phenomenon is analyzed by available techniques: 1- System Thermalhydraulics (TH) to calculate boron dilution process and transport; 2-Computational Fluid Dynamics (CFD) to study mixing in boron diluted and non-diluted, 3-Three-dimensional Neutron Kinetics (3D NK) to study effects of boron diluted plugs in the physics of neutrons. The key findings were to set-up a suitable computational system to address relevant phenomena involved. Regarding TH system codes, it was demonstrated that TH system codes are suitable to investigate formation and transport of significant non-borated plugs in loop seals of PWRs after a SB LOCA. Regarding 3D NK and CFD codes, information, working knowledge and expertise were acquired. Ways.
