Scientists have long manipulated the process of fission, in which an atom splits into two smaller pieces. This occurs naturally as well as by human manipulation. The natural occurrence takes millions of years, but scientists now can speed up the process through induce fission.

The most common element used for nuclear power is uranium. Uranium’s natural fission process takes millions of years. For example, the half-life of Uranium, or the amount of time for Uranium to lose half of its mass, takes 4.5 billion years.

Uranium occurs naturally in three forms. These three forms are Uranium-238, -235, and -234. All three undergo natural fission when radioactive decay sets in, but scientists have found that they can induce fission when using Uranium-235.

Overtime, Uranium will experience decay by alpha radiation, a natural occurrence in which an alpha particle, made

Civil engineers which possess an academic degree with a major in civil engineering is one of most important job in the world ,civil engineering is a professional engineering discipline that deal with the design ,construction and maintenance of physical and naturally built environment that include work such as bridges , roads ,canal ,dams and building. university offer the course usually three to five years and designate the degree as bachelor of engineering.

As a civil engineer should be completely open-minded about the direction of career and realize the short and long term goal to think ahead and look ahead ,prepare much more knowledge to adapt the changing world .This job need the good team working spirit ,we try to work in a lot of group and working with people in different discipline together ,the manufacture or industry need the student have more experience of job as a
