Consider the following statements: 1. Indira Gandhi Centre for Atomic Research uses fast reactor technology. 2. Atomic Minerals Directorate for Research and Exploration is engaged in heavy water production. 3. Indian Rare Earths Limited is engaged in the manufacture of Zircon for India's Nuclear Programme beside other rare earth products. Which of the statements given above are correct?

Evaluating statements about Indian nuclear and research institutions: 1. Statement 1 is correct. The Indira Gandhi Centre for Atomic Research (IGCAR) at Kalpakkam focuses on research and development related to sodium-cooled fast reactor technology, including the Fast Breeder Test Reactor (FBTR) and the Prototype Fast Breeder Reactor (PFBR). 2. Statement 2 is incorrect. The Atomic Minerals Directorate for Research and Exploration (AMD) is primarily responsible for the survey, prospecting, and exploration of atomic minerals (like uranium, thorium) required for the nuclear power programme. Heavy water production is handled by the Heavy Water Board (HWB). 3. Statement 3 is correct. Indian Rare Earths Limited (IREL) processes mineral sands to produce various rare earth products, ilmenite, rutile, and Zircon. Zirconium, derived from zircon, is used as cladding material for nuclear fuel rods in India's Nuclear Programme. Therefore, statements 1 and 3 are correct.
