The strategy for the growth of nuclear power in our country in the rst half of the 21st century provides for building and commissioning new-generation fast reactors with different coolants: sodium (BN-800, BN-1200, MBIR) and lead (BREST-OD-300). Structural materials with the required level of radiation and heat resistance as well as corrosion resistance upon exposure to the ssion products of nuclear fuel, in the coolant, and the spent-fuel pool must be developed for the reactor cores in order to ensure the performance of the reactors under construction and to reach economically expedient burnup of nuclear fuel. The basic results of the performance validation of structural materials in application to their use in the cores of operating (BOR-60, BN-600) and advanced fast reactors with different types of coolants as well as the prospects for further advancement of the research are presented.
The strategy for the development of nuclear power in our country in the rst half of the 21st century provides for the construction and commissioning of new-generation fast reactors with different coolants: sodium (BN-800, BN-1200, and MBIR) and lead (BREST-OD-300). To ensure reactor performance and attain economically expedient burnup of nuclear fuel, it is necessary develop and validate for the reactor cores structural materials possessing the requisite radiation resistance and heat resistance as well as high corrosion resistance in the presence of interaction with the ssion products of nuclear fuel, in the coolant, and in the water in spent fuel pools.
The main results of performance validation of the structural materials for use in the core of operating (BOR-60, BN-600) and advanced fast reactors with different types of coolants as well as the prospects for further advancement of research are presented here.
Structural Materials of the Cores of Sodium-Cooled Fast Reactors. A program of comprehensive research on the development of radiation-resistant materials was initiated at the beginning of the 1980s. Different steels and alloys were tested in the BOR-60, BN-350, and BN-600 reactors as part of this...
