Section 15. Requisitioning of any substance for extracting uranium or plutonium.

(1) The Central Government shall have the right to require that any substance which, in the opinion of the Central Government, contains uranium, plutonium or any of their isotopes, shall be delivered to it and the Central Government may extract from that substance the uranium, plutonium or any of their isotopes contained therein and return the substance to the person concerned on payment of compensation which shall be determined in accordance with section 21: Provided that such compensation shall not, in any case, exceed the cost incurred by the person in the production, mining or irradiation of the substance and in determining the same no account shall be taken on the value of the uranium, plutonium or any of their isotopes extracted from the substance. (2) Nothing in this section shall prevent the Central Government from permitting, subject to such conditions as it may deem fit to impose, the use of small quantities of natural uranium for the purpose of examination, test or analysis.
