Head Chyrko L.I., Registration Date 25-11-2011 Organization Scientific Center "Institute for Nuclear Research" of National Academy of Sciences of Ukraine popup.description2 It is shown, that temperature dependence of fracture toughness of WWER-1000 reactor materials observed experimentally is highly correlated with Master curve form both in the initial state and after the irradiation to neutron fluence 3x10^23 neutr/m2. The lowering of radiative loading on the reactor vessel due to introducted principle of forming of active zone with reduced neutron leakage may be used for prolongation of the life-time of KhNPP-1 Product Description popup.authors popup.nrat_date 2020-04-02 Close
