Graphite and cold stack

WatereoledgraphiteModer-Fedreactor with graphite as a slow neutron reactor with graphite as a chronic agent and water as a cooling agent. In the early days of the development of the nuclear industry, graphite and cold stacks were mainly used to produce nuclear weapons installation -钚, 氖, etc. This heap is generally fuel with natural uranium metal components. Uranium 235 in the natural uranium in the pile absorbs neutron reactor in neutron and releases neutron and energy. These neutron parts are used to maintain chain nuclear fissure reactions, and some are absorbed by the uranium 238 in natural uranium and converted into it to converted into it into. 钚 239 and other 素 isotopes. Structural graphite and cold stacks use nuclear pure graphite masonry as a chronic agent and reflective layer. There are two or three thousand horizontal tunnels (horizontal piles) or vertical tunnels (vertical piles) in the graphite masonry. Inserting graphite sleeves in these holes, aluminum alloy crafts pipe

Main characteristics of graphite crucible

1. High thermal conductivity: Due to the use of raw materials such as graphite with high thermal conductivity, the melting time is shortened.2. Heat resistance and shock resistance: Strong heat resistance and shock resistance, resistant to cracking during rapid cooling and heating.3. High heat resistance: High fire resistance, capable of withstanding high temperatures ranging from 1200 to 1600 ℃.4. Erosion resistance: Strong resistance to erosion of molten soup.5. Resistance to mechanical impact: Having a certain degree of strength to resist mechanical impact (such as the input of molten materials).6. Oxidation resistance: Graphite is prone to oxidation at high temperatures in oxidation aerosols, and due to oxidation prevention treatment, oxidation consumption is relatively low.7. Anti adhesion: Because graphite has the characteristic of not easily adhering to molten soup, the immersion and adhesion of molten soup are less.
