Graphite reactor
WebThe reactor itself, nicknamed “Chicago Pile-1” or CP-1 for short, was a 20-foot-tall pile of graphite blocks studded with hundreds of smaller blocks of uranium. Crews worked round the clock for two weeks, purifying graphite and uranium, arranging the blocks in 57 layers of precise positions, and fitting holes for cadmium control rods. WebThe BGRR was an air-cooled, graphite-moderated reactor. It was enveloped in a biological shield made of high-density concrete containing scrap iron and limonite. During reactor operations, outside cooling air …

WebThe surplus production reactors, which are graphite-moderated and water-cooled, were used to produce plutonium and other special nuclear materials. As shown in Figure 1, each reactor building contains inner and outer rod rooms, laboratory areas, fuel storage basins, and the reactor block. WebThe graphite bricks act as a moderator. They reduce the speed of neutrons and allow a nuclear reaction to be sustained. They also perform an important safety function by providing the structure through which CO2 gas flows to remove heat from the nuclear fuel and the control rods used to shut down the reactor are inserted.
WebGraphite has been used in nuclear technology since the birth of this technology. The first artificial nuclear reactor, the Chicago Pile-1, consisted of a pile of uranium and graphite.
