graphite core造句

• In October 2016 it was announced that super-articulated control rods would be installed at graphite cores.
• In the furnace, an electric current was passed through a graphite core, surrounded by sand, salt, and carbon.
• The small clearance between the pressure channel and the graphite block makes the graphite core susceptible to damage.
• The Magnox reactors used natural uranium fuel ( in magnox alloy'cans') within a graphite core, and were cooled by carbon dioxide gas.
• Some versions also offer a regulator of the desired sharpness, since it is not always desired to make the graphite core needle-sharp.
• The electric current heated the graphite and other materials, allowing them to react, producing a layer of silicon carbide around the graphite core.
• The graphite cores each weigh; 6, 156 vertical fuel channels contain over 49, 248 natural uranium magnox-clad fuel elements, hence the name magnox reactor.
• In October 2016 it was announced that super-articulated control rods would be installed in the reactor because of concerns about the stability of the reactors'graphite cores.
• The 1986 explosion and fire in the graphite core of the Chernobyl plant in the Ukraine killed at least 31 people and is the worst nuclear accident in history.
• The plant's design is not the Chernobyl-style graphite core reactor that is of greatest concern to Western governments, but is based on pressurized water reactors within a containment building.
• There have also been several experimental reactors that use graphite for moderation, such as the pebble bed reactor concepts and the molten-salt reactor experiment ( graphite core shown at right ).
• The Dungeness B restraint couplings-mechanical linkages that held the graphite core in place whilst allowing it to expand and contract in response to temperature changes-were made of mild steel and could be subject to the same corrosion.
• The cylindrical graphite core was surrounded by twelve rotating control drums with beryllium on one side to reflect neutrons and boral on the other side to absorb neutrons to control the rate of the nuclear reaction in the core.
