WebThe maximum allowed temperature of the graphite is up to 730°C. [11] The reactor has an active core region 11.8 meters in diameter by 7 in height. There are 1700 tons of graphite blocks in an RBMK-1000 reactor. [8] The pressurized nitrogen in the vessel prevents the escape of the helium-nitrogen mixture used to cool the graphite stack. WebNuclear Graphite. Next-generation nuclear reactors (Gen IV) will be high-temperature, gas-cooled reactors with graphite used as a core and moderator material. These reactors involve high operating temperatures as well as very high neutron dose rates, placing increased emphasis on strength, creep, and creep-fatigue behavior of the materials used.
