Abstract Scope |
Tungsten transmutes to rhenium and osmium under neutron irradiation. Recent research indicates that transmutation effects in tungsten dominate the degradation of its mechanical and thermophysical properties. Oxford Sigma is developing technology that suppresses the rhenium and osmium production via enrichment of selective tungsten isotopes in order to improve the neutron radiation damage resistance. The displacement of tungsten-186 suppresses the production of rhenium and osmium isotopes via transmutation. Oxford Sigma’s isotopically enriched tungsten mainly transmutes to tantalum, an element that is soluble within the matrix. This talk will discuss the latest project development on isotopically enriched tungsten [1]. Modelling work, such as inventory modelling and neutronics, will be presented. In particular, the possibility of improving the mechanical and thermal properties will be discussed. Moreover, this talk will discuss a pathway for commercialising such a technology to accelerate the development of fusion energy.
