| titleOfInvention | Device for passive protection of nuclear reactor |
| abstract | FIELD: nuclear energy.SUBSTANCE: invention relates to systems for protection of nuclear reactors and can be used in designing nuclear reactors, in particular fast neutron reactors. Device for passive input of negative reactivity is made in the form of two reservoirs located in a common casing one under the other, between the reservoirs and the casing an annular cavity is formed for passage of the heat carrier. Fuel elements are arranged in the annular cavity, as well as means for generation of the heat carrier flows for cooling the fuel elements and for heating the upper reservoir. Upper reservoir is located above the reactor core and is divided by an internal partition into a central cylindrical and an annular cavity. Partition is made with low thermal conductivity in the transverse direction. In the central cavity of the upper reservoir there is cadmium, and in its annular cavity – mercury. Lower reservoir is arranged, mainly, in the reactor core and filled with an inert gas. Reservoirs are interconnected by a pipe with a partition in the form of a buckling safety membrane.EFFECT: technical result is improvement of reliability of passive input of negative reactivity in various emergency modes.10 cl, 3 dwg |
