Which one of the following statements is correct?(a) Liquid Sodium …

Notes: A Sodium-cooled Fast Reactor (SFR) is a type of nuclear reactor that utilizes molten sodium metal as the reactor coolant as it allows for a high power density with a low coolant volume. [3] An SFR can achieve a core power density of around 300 MW/m3 compared with Pressurized Water Reactors (PWR) that achieve 100 MW/m3. ...

Which one of the following statements is correct? (a) Liquid sodium …

(a) Liquid sodium is used as a coolant because water is difficult to use as a coolant for a fast reactor because water acts as a neutron moderator that slows the fast neutrons into thermal neutrons. While it may be possible to use supercritical water as a coolant in a fast reactor, this would require a very high pressure.

Can sodium be used as coolant? – Pleasefireme

Why is liquid sodium used as coolant? The primary advantage of liquid metal coolants, such as liquid sodium, is that metal atoms are weak neutron moderators. Water is a much stronger neutron moderator because the hydrogen atoms found in water are much lighter than metal atoms, and therefore neutrons lose more energy in collisions …

Sodium in Oil

Sodium can come from Coolant. When coolant leaks into the engine, it drain down into the sump. At standard operating temperatures, the water boils off and leaves behind sodium trace elements.

NaK Coolant

NaK Coolant is an alloy of sodium (Na) and potassium (K) used as a coolant in nuclear reactors. It is particularly useful in these situations because it remains liquid at room temperature and is commercially available in various grades. NaK is highly reactive with air or water, and as a consequence must be handled with special precautions.
