Opening titles: Nuclear Reactors for Research (:06-:08). A scientist climbs the steps to a low powered, research reactor. It is used for nuclear research. Geiger counters are used, isotopes are removed. A woman uses a geiger counter. Scientist fills out a sheet on a clipboard. Compact solution type reactor shown via animation. A diagram shows the way the tank is set and how it works. Steel housing is used. The rods are shown in the diagram (:09-2:24). How the mixing chamber and core work. Uranium fission chain reaction is shown and explained via animation. Neutron and Uranium nucleus are shown and explained. Fission process shown and explained via animation (2:25-3:49). Shut down rods are shown and discussed via animation. Ionization chambers. Reactor power level. Layer of lead. Concrete blocks helps with shielding. Overhead view of the reactor shown via animation (3:50-5:02). Overhead view of the reactor explanation. Safety feature provided by a plastic model which shows what would happen if there was a problem and safe shutdown occurs (5:03-6:16). Construction of a nuclear reactor. This is shown and explained in detail. Graphite blocks are lowered inside. In a laboratory, the core is checked and reviewed (6:17-7:25). Scientists turn on a machine. Leak detector. Core in the assembly area. Pipes are installed. Men place pipes into and coming out of the reactor. Gas handling system, flow meters tested. Men hammer a crate (7:26-8:59). Men continue to build around the reactor. Uranium is transferred as a liquid to a plastic bottle. It is poured into a stainless steel mixing chamber. Water is added as well (9:00-10:18). A man connects a hose. A man hands a woman an item. She turns on a machine. She jots down numbers and figures. She uses a ruler. Reactor is ready for operation (10:19-11:37). A man sits in the control room. He presses a button. Power level increases slowly. Rod dial. Counting rate meter. Reactor reaches its operating level (11:38-12:47). Man sits in the control room for the reactor. A rod is inserted into a reactor. Scientists perform tests (12:48-13:36). End credits (13:37-13:49).
