Chemical characterization of lithium titanate and lithium aluminate as tritium breeders of fusion reactor by PIGE and INAA methods

Lithium titanate and lithium aluminate, proposed as tritium breeding blanket materials in D–T fusion reactor, were analyzed by nuclear analytical techniques as a part of chemical quality control exercise. Concentrations of Li, Ti and Al were quantified by particle induced gamma-ray emission using 4 MeV proton beam from folded tandem ion accelerator facility. Trace elemental concentrations belonging to long-lived nuclides were determined by instrumental neutron activation analysis using neutron flux from Dhruva research reactor at BARC. The analysis results are useful in designing a shielded facility for tritium release studies of these irradiated breeder materials.
