Optimization of the technological solutions for recharge and boron control system at the NPP for the project AES-2006

Abstract

The article considers the possible ways to optimize the technological solutions of the recharge and boron control system of nuclear power plants under construction within the AES-2006 project. The possibilities for optimization of technological solutions of the system of recharge and boron regulation of the AES-2006 project, which will not affect the reliability and efficiency of its main functions: purge-recharge of the primary circuit and boron regulation, were studied. As a result of the analysis of technological solutions and analytical calculations carried out during the work, it was found that in the system of recharge and boron regulation of the NPP within the project AES-2006 it is possible to perform optimization basing on reduction the metal content of the heat exchange equipment by reducing the surface area of the heat exchangers of the coolant outlet, reducing the power of pumps, as well as reducing the diameter of a number of main pipelines. Implementation of the proposed optimization of technological solutions will allow a more rational arrangement of the system and reduce capital costs for the construction of nuclear power plants as a whole, while not adversely affect the safety of the system and its functions.

The new ways to increase the efficiency of thermal hydraulic processes in systems of separation and reheating of NPP wet steam turbines

“…The moisture separation and reheating organisation of low-pressure steam in turbine units of nuclear power plants with water-cooled reactors is the problem, appeared with the steam turbines creation operating on saturated steam, i.e. simultaneously with the large-scale nuclear power advent in the USSR and in other countries (in early 1960s) [1]. The steam parameters are significantly lower than the standard reheated steam parameters of used in organic fuels power engineering.…”
