Such information could onl1y be obtained from agent reports or infrared imaging of the targets. which would reveal the heat associated with nuclear-refining activity. Early in 1963 the Agency sought special funds from the Pentagon to de velop a high-resolution infrared scanner for the U-2 in order to ascer tain the operntional status of Chinese nuclear reactors. After this request was turned down. the Agency decided to fund the develop ment of such a scanner itself.
