Název v původním jazyce

High-temperature embrittlement of ferritic ODS steels in Pb/Pb-Bi coolants

Popis výsledku v původním jazyce

The oxide dispersion strengthened steels (ODS) are consider as a structural material of the proposed future nuclear energy production systems developed: i) the generation IV fission reactors, ii) fusion reactors and iii) spallation neutron sources. Several of these future concepts foresee the use of lead-based coolant (lead-cooled fast reactor and spallation target), as well as for breeder carrying material (helium-cooled lithium-lead fusion reactor). Compatibility of structural materials working at thelimiting conditions in heavy liquid metal (Pb-based) environments is a very important issue. The embrittlement of the steel was explained by the porosity development and precipitates coarsening in the bulk of the steel and intercrystalline corrosion ofthe surface of the steel during long-time high-temperature exposition in liquid metals.
