In monazite ore deposits on the west of the Kirovograd area, the variety of the mineral by an age of 2 billion years practically without uranium, which contains ∼10% of thorium and ∼1% of lead with cleanliness of 98% on 208 isotope is established. It is predicted that such lead may be a perspective coolant for reactors of the IV generation without additional isotope enrichment. The method and results of searching for such raw material are described, the content of elements and structural characteristics of the mineral are presented, and the estimation of its resources is done.
