Liquid sodium (Na) has a very wide range of operational temperature (371–1155 K) and chemically stable up to near 1173 K with high thermal conductivity (Liu et al., 2019; Pacio et al., 2013).

Liquid sodium is used as a heat transfer fluid in some types of and low neutron absorption cross-section required to achieve a high neutron flux in the reactor. The high thermal conductivity properties effectively create a reservoir of heat capacity, which …

Oct 13, 2014 · Liquid sodium is better than water at evacuating heat from the reactor core and its high boiling point of about 900 degrees Celsius allows SFRs to operate close to atmospheric pressure, negating...

The sodium-cooled fast reactor (SFR) uses liquid metal (sodium) as a coolant instead of water that is typically used in U.S. commercial power plants. This allows for the coolant to operate at higher temperatures and lower pressures than current reactors—improving the efficiency and safety of the system.

Mar 29, 2025 · Liquid selenium and tellurium both react vigorously with solid sodium to form selenides and tellurides. Sodium shows relatively little reactivity with carbon, although lamellar (layerlike) materials can be prepared in which sodium is present between graphite layers.

Liquid metals, such as sodium, exhibit superior thermal conductivity compared to conventional heat transfer fluids (HTFs) such as water and oil, enabling them to absorb and transfer heat efficiently.

May 25, 2024 · Learn how liquid sodium’s superior thermal properties enhance heat transfer in nuclear reactors, improving energy efficiency and safety. One of the most critical aspects of nuclear reactor efficiency and safety is the method used for heat transfer.

Apr 1, 2018 · Single-phase liquid sodium as a kind of ideal coolant is widely applied in the fields of nuclear reactor engineering, aerospace, solar energy and industrial waste heat utilization, due to the good heat transfer and flow characteristics.

Liquid sodium is used as a coolant in fast breeder reactors on account of its excellent heat transfer properties. It must, however, be in the pure form to be compatible with structural materials.

Jan 21, 2025 · Here are six key sodium compounds along with their chemical equations: Common table salt, used in food and as an industrial chemical. A strong base used in soap making, paper manufacturing, and as a chemical reactant. Known as soda ash, used in glassmaking, detergents, and as a water softener.
