Reactor system description and development status of unattended low power NP SAKHA

The low power SAKHA-92 nuclear power plant is intended for generation of electric energy or combined generation of electricity and heat in independent regions with poor access isolated from power networks. The NPP may be used for sea water desalination as well. 

The major design decisions which provide for the high safety level of SAKHA-92 are the following. 

The NPP structure is designed for prefabrication and delivery to the site in the form of three main modules weighing 90 tons each. 

The reactor plant (Fig.7.10.1.) uses a self-pressurized integral reactor (Fig.7.10.2.) in the vessel in which the core with the protection system, the heat exchanger and steam-gas pressurizer are located. 

The reactor vessel is a prefabricated forged-welded vessel with elliptical bottom of 4230 mm hdght and 1 860 mm diameter. There are 2 nozzles (ND 80) for steam removal and 2 (ND 40) for feed water supply in the upper part of the vessel.
