Abstract

The code TRETOH is intended for the thermohydraulic calculation of transient, spatially-distributed processing in a VVER core with shell-less fuel assemblies. It implements algorithms for the multi-level solution of the equations of heat transfer and hydrodynamics. The aim of this paper solved based on the development of a porous body model for the core of the reactor. The coefficients of effective thermal conductivity and viscosity were determined, as well as the formulations of the boundary conditions were refined and calculate thermal-hydraulic characteristic parameters of the VVER-1000 reactor when the reactor is run efficiently 104%and 106%. The results include the improvement of the mathematical model and the TRETON software, which showed that it gives a very good agreement with the thermal-hydraulic calculations and with high accuracy. Through the results obtained it can operate the reactor efficiently with 106%, confirming its compliance with the requirements of safe operation.
