At the Nevada Test Site (NTS) Kiwi A, the 100,000-kilowatt experimental reactor designed to use graphite-based fuel elements, completed two short criticality runs to establish power calibration. No technical difficulties were encountered and radiation levels outside the reactor were insignificant. Actual power operation is to follow the individual testing of subsystems and the integral testing of the heavy and light water cooling systems and gas flow systems. —— “16 2 IETS oo ver -—
