Benefits of technology

[0009]To achieve the above purpose, the present invention is a hydrogenation electrolysis apparatus, comprising a first electrode, a second electrode, an electrolyte solution and a direct current (DC) power source, where the first electrode and the second electrode is put in the electrolyte solution; the anode of the DC power source is coupled to the second electrode and the cathode of the DC power source is coupled to the first electrode; the first electrode is made of Zr and the electrolyte solution comprises an acidic solution and

Problems solved by technology

As a result, a hydrogen embrittlement is happened to the Zr tube, and crack or hole may appear to the Zr tube to leak the U235.
Thus, a study on the hydrogen embrittlement of the Zr tube is an important issue.
Although a great sum of hydrogen is left on the Zr tube, the time spent is too long.
It becomes a big issue for this prior art on shortening the reaction time.
Hence, the prior arts do not fulfill all users' requests on actual use.

Abstract

The present invention provides an apparatus for rapidly grow zirconium hydride (ZrH2) on a Zr tube. ZrH2 is obtained through electrolyte in a hydrogenation. The electrolyte uses As2O3 as a catalyst to speed up the deposition of ZrH2.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a hydrogenation; more particularly, relates to an electrolysis apparatus for speeding up a hydrogenation of zirconium hydride (ZrH2).DESCRIPTION OF THE RELATED ARTS[0002]Nuclear power is one of the most important power source nowadays. A chain reaction of U235 is utilized to release a tremendous sum of power. In general, U235 is filled in a zirconium (Zr) tube for a nuclear fission reaction. Because the Zr material has a small neutron absorption cross-section, neutron is not easily trapped by the Zr tube and thus the fission reaction continues. In the other hand, the Zr tube has a good resist to corrosion and a good mechanical strength under high temperature. Thus, the Zr tube is used as a protection for U235 material.[0003]In a nuclear power generation, water is usually used to transfer power obtained from the nuclear fission reaction. However, the Zr tube would react with water to obtain hydrogen through an oxidation rea...
