Рurpose Subject of diploma project is a design of NPP with a capacity of 1,800 MW and with two BN-900 reactors . It’s main purpose is the production of electricity in the Trans-Baikal Territory. Its operation will enhance opportunities for development of the region due to the increase in electricity generation and replacement of decommissioned (state district power stations)GRES. So it is necessary to choose main equipment and make neutron-physical, thermal-hydraulic and economic calculations. Design / Methodology / Approach Neutron-physical parameters were calculated by four-group approximation method using four zones reactor model with end and side reflectors. Сhanges of the temperature of coolant, fuel cladding and in the center of the fuel pellet were determined by thermal hydraulic calculation . The calculation of technical and economic indicators allowed us to estimate the cost of construction of NPP and other economic indicators. Special Task Subject of special task is technological channels integrity system «TCIS». TCIS is an integral part of the gas circuit system of the reactor. TCIS system is an integral part of the gas circuit system of the reactor . It is designed to identify leaky channels when the reactor is operating in the energy mode. The modernization directed at reducing the number of technological channels belonging to one group is considered. Findings. Designed BN -900 reactor is safe from the point of view of neutron-physical and thermo-hydraulic calculation results. The main equipment of the plant was chosen. On the basis of technical and economical results it can be approved that the cost of electricity is quite low, the projected NPP has reasonable pay-back period. It can be expected that the creation of the reactor facility based on BN is advisable.
