V.V. Saprykin, I.I. Yasnopolskaya, A.N. Novikov RRC "Kurchatov Institute", Moscow, Russia

17th Symposium of AER on VVER Reactor Physics and Reactor Safety (2007, Yalta, Crimea (Ukraine, back then))


The paper has as an objective to make conclusions for works performed on modernization of VVER-440 fuel cycles. Possibilities and perspectives on further improvement of neutronics and operation characteristics of VVER-440 are discussed basing on additional optimizations of fuel assembly design and of fuel load patterns. Discussion is applied to reactor operation with power levels of 100 and 112% comprising equilibrium refueling regimes.
