Why in news

A Bhabha Atomic Research Centre (BARC) study concluded that HALEU-Th fuel is unsuitable for India's current reactors, sparking a clash with Clean Core Thorium Energy (CCTE) over thorium-based fuel potential.

Background

The Bhabha Atomic Research Centre (BARC) conducted a study on HALEU-Th (a mix of concentrated uranium-235 and thorium). Clean Core Thorium Energy (CCTE), an American company, claims the fuel has potential benefits and has tested ANEEL fuel in a US reactor.

Facts for Prelims

S&THALEU-Th: A fuel mix consisting of concentrated uranium-235 and thorium.
BodyBARC: Bhabha Atomic Research Centre, the primary nuclear research body in India.
