How much temperature can be controlled by liquid sodium in nuclear reactors?

Liquid sodium has been used as a coolant in fast reactors, because it does not slow down and absorb fast neutrons. It does not control the nuclear reaction directly, for that variable neutron absorbers are required.

Does liquid sodium is used as a coolant in nuclear reactors?
In some reactors it is, depends on the design.
Are there liquid metal?
Pretty much all metals can melt if you get them hot enough. Mercury is normally liquid at room temperature. The melting point of eutectic mixtures of many gallium alloys are also liquid near room temperature - so is sodium-potassium alloy. Some nuclear reactors have used molten (liquid) metals as the circulating/cooling fluid.
What can be used in as a coolant in nuclear reactors?
The most successful have been light water and carbon dioxide. Liquid metals like sodium have been tried experimentally, and helium gas might be used in a high temperature reactor.
What has the author W E Kastenberg written?
W. E. Kastenberg has written: 'Anticipated transients without scram for light water reactors' -- subject(s): Safety measures, Nuclear reactors, Liquid metal fast breeder reactors
Liquid sodium can be used to cool nuclear reactors. If it takes 1395 g to fill a contained of 1500 mL what is the density of the liquid sodium?
1395g/1500mL = 0.93g/mLCome on its simple math!Mass/Volume = Density
How are nuclear reactors classified?
There are 1. Light water reactors. PWR and BWR, 2. Heavy water reactors, CANDU mainly, 3. Gas cooled reactors, mainly magnox and AGR in the UK, possibly pebble bed reactors not yet built 4. 'Fast' reactors which do not use moderators, liquid metal cooled. 5. Small research reactors also used to produce radioisotopes for medical and industrial use.There are a few other diverse types like the Russian RBMK (Chernobyl), now obsolete.
What is something that is made of indium?
Several applications of indium:- in liquid alloy at r.m. called gallinstan- in aluminium alloy for some anodes- standard in thermometry- vacuum sealing- component of some control rods for nuclear reactors
What are the popular states of matter?
The most common states of matter on Earth are solid, liquid and gas.There is a fourth state, plasma, which requires high temperature and pressure, and is thus found on our planet mostly in science labs and nuclear reactors. But it's a much more popular state of matter in the universe at large, as it's what the bulk of stars (including our own sun) are composed of.
What metal do power stations use as a liquid cooler?
Most current nuclear power plants just use ordinary wateras coolant.However experimental reactors have been built using:MercuryNaK - Sodium Potassium alloyLeadSolder - Tin Lead alloyOil (which also acts as moderator to slow neutrons)etc.NaK was the most common in fast breeder power reactors.
Is nuclear fusion used as an energy source in power plants?
Nuclear power plants use controlled atomic fission to generate electricity. Atoms of the fissile material are split and part of their mass is converted to energy in addition to neutrons being ejected from the nucleus. These neutrons impact other atoms within the fissile material which then release further energy and more neutrons. The reaction is controlled by absorbing most freed neutrons with material so an uncontrolled chain reaction doesn't occur like the atom bomb used in WWII. The energy released produces heat (and radiation) which heats liquid into steam turning turbines connected to electric generators to make electricity. The highly radioactive spent fuel is a dangerous waste product that must be warehoused for many lifetimes. Conversely, the simplest type of nuclear fusion, which may become a reality this century, converts hydrogen atoms into helium atoms and produces no radioactive waste products.
What is used as a cooling medium for nuclear reactors?
Different things are used in different designs:water (most common)liquid metals (e.g. mercury, sodium, potassium, NaK alloy)airinert gasses (e.g. helium, nitrogen, argon)etc.
Is nuclear a liquid?
nope
