Neutron moderator

The Nuclear Age was a very horrific period in world’s history due to many deaths and casualties. Thousands of people died in a matter of a year. From the radiation to destruction, the Nuclear Age made people realize we humans have the power to destroy Earth and it’s abundant ecosystems. Nuclear Age was a great way for the scientists to understand our world, understand our world’s fragility and advances in technology. From Hiroshima to Nagasaki bombing, a new type of energy (Nuclear Power) became…

Pressurised Water Reactor (PWR) PWR is the most commonly use type of nuclear reactor, with over 230 of PWR used for electrical generation and several hundred more used for nuclear power naval ships/submarines. PWR reactors use water as both coolant and moderator. PWR works by having a primary cooling circuit using very high pressured water to flow through the core of the reactor, and another circuit that uses heated steam that had been generated to drive the turbine. (World Nuclear Association,…

good strength and a high melting point. Additionally, it is a good electrical conductor, has high modulus of elasticity, exceptionally transmit x-rays and sounds at very high velocities. Moreover, it has the ability to act as a source, moderator and reflector of neutrons. It can be forged, rolled and extruded, machined, punched, sheared and casted by vacuum casting. Commercially, it is available in block, rod, sheet, pebble, metal disk, foil and powder form. Beryllium…

For example, they miscalculated the amount of graphite and heavy water needed for a moderator. This was one of many issues that hindered the Nazis from completing an atomic…

India 's nuclear programme started on March 1944 and its three-stage efforts in technology were established by Dr. Homi Bhabha when he founded the nuclear research centre, the Institute of Fundamental Research. Bhabha drew up the blue print of the nuclear energy programme in India. Based on early geological surveys, he decided that the vast deposits of thorium in the monazite sands of Kerala could be harnessed for securing India’s long-term energy needs. Thorium is particularly attractive for…

reactor, which used “enriched U-235 uranium fuel to heat water creating steam that drives the reactors’ turbines and generate electricity” (http://www.livescience.com/39961-chernobyl.html). The plant had 4 reactors with graphite moderators, which slows down the release of neutron during fission. Essentially, used to maintain the chain reaction. The reactors were powered by enriched uranium oxide pellets enclosed in a fuel rod. As for the coolant, general there is two water loops that circulate…
