Heat accumulators at nuclear power stations

Conclusions It has been shown to be technically possible and economically desirable to introduce heat accumulators into nuclear power stations and CHPS, particularly FWA, DHWA, and DSWA. The largest power-control range is attained with HA of DHWA, PTA, and DSWA types and is 120–140% for stations with HA of the water class in relation to the nominal reactor power or up to 160% for stations with PTA.The inclusion of HA in a nuclear station provides higher PUF and consequently maintains high rates of production for secondary nuclear fuel with nuclear stations working in variableload mode. The introduction of HA at nuclear stations will enable one to fit turbines of power 1.2–1.4 times larger than the reactor power with HA of the water class or by more than a factor 1.5 for PTA, which provides a reliable means of covering peak loads by means of nuclear stations.Translated from Atomnaya Énergiya, Vol. 56, No. 6, pp. 389–396, June, 1984.
