Efficiency of producing additional power in units of nuclear power stations containing water-cooled-water-moderated reactors

Abstract

There is a basic possibility to raise the maximum power of a unit containing the VVER-1000 reactor in the course of the fuel charge burn-up and with lowering the coefficient of the energy-release nonuniformity in the reactor core. It is more advantageous economically to obtain additional power in carrying the peak load. With the duration of such operating conditions for 1000–2000 h/yr savings can amounts to 1–4 million rubles per year per 100 MW of additional power when compared to peaking GTP.
