NUCLEAR PROPERTIES OF URANIUM•U isotopes all alpha emitters. •Some spontaneous fission (SF). •Specific activity of U low due to long half-lives …. but … •Decay through chain of daughter products, ultimately leading to lead or bismuth. •At secular equilibrium: –All...

The nuclear fuel cycle is the series of industrial processes which involve the production of electricity from uranium in nuclear power reactors. Uranium is a relatively common element that is found throughout the world. It is mined in a number of countries and must be processed before it can be...

As we near the end of the century, the disposal of nuclear waste is becoming a concern. Many nuclear power plants around the world are nearing the end of their operating lives. The disposal of radioactive waste from nuclear power plants and nuclear missiles is as politically intense an issue as the...

Fast neutrons produced in the fission reaction are slowed when they bounce off light atoms such as hydrogen or carbon and contains a large amount of such moderating material to slow down the fission neutrons. This takes advantage of the fact that the probability of a neutron being absorbed into another...

Thermal and fast nuclear reactors A nuclear reactor converts the fissile components, such as 235U, of nuclear fuel into energy, and fertile components, such as 238U, into fissile components and then into energy. A fissile atom is one that is very likely to be fissioned (split) when a neutron is absorbed, thereby enabling a nuclear chain reaction....

What is Greenhouse Gas? Greenhouse gas is a gas in atmosphere that absorbs and emits radiation. 3 priority Greenhouse gases in Malaysia is carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). How to control the Greenhouse Gas? First we have measure the emission of the greenhouse gases....

The Klang Valley Mass Rapid Transit is a proposed 3-line 150 km Mass Rapid Transit ‘”(MRT)”’ system in the Klang Valley/Greater KLconurbation which envisages a “Wheel and Spoke” concept comprising two northeast-southwest radial lines and one circle line looping around Kuala...
