Study on Sodium Nanofluid for Fast Reactor (2)Reaction Suppression of Sodium Nanofluid

Nagai K., Saito J., Ara K., Japan Atomic Energy Agency, JP

　　Liquid sodium is used for a coolant of fast reactor, because of its superior thermal properties and high melting temperature etc. However liquid sodium has high chemical reactivity with oxygen or water. This is the [...]

Study on Sodium Nanofluid for Fast Reactor (1)Concept of Sodium Nanofluid

Saito J.-I., Nagai K., Ara K., Japan Atomic Energy Agency, JP

Liquid sodium is used for a coolant of fast reactor (FR), because it has superior properties. For example, there are high heat conductivity, high melting temperature and excellent compatibility with structural materials. However high reactivity [...]

The concept of a superconductor of man-made 1D superlattice

Inoue A., Japan Atomic Energy Agency, JP

It is well-known that man-made 1D superlattice structure (for instance, GaAs-Ga1-xAlxAs prepared with alternating epitaxy) exhibits a resonant tunneling phenomenon. The mean free path of an electron is, however limited to the order of 100 [...]

The interpretation of the conventional superconductivity on the basis of hypothesis of small polaron

Inoue A., Japan Atomic Energy Agency, JP

The mechanism of conventional superconductivity is well-known to be able to be explained on the basis of BCS theory which is based on the ambiguous correlation between a normal state and superconductive state of metals. [...]
