Depleted uranium

using a liquid nuclear fuel, not a solid fuel. MSRs also use a coolant that remains liquid at atmospheric pressure. LFTRs are designed to convert Thorium, an inexpensive and abundant material, into Uranium-233 which can then undergo nuclear fission. Other types of MSR can use spent uranium, depleted uranium, or plutonium, eliminating nuclear waste from solid-fueled reactors. Most safety concerns of LWRs are from using water coolant; LFTR is a molten salt reactor (uses special salt…

Term Paper - Light Water vs Breeder Nuclear Reactor to Replace Grid Introduction One of the most critical global challenges in society is the challenge of energy. The world’s dependence on nonrenewable fossil fuels that power the grid. For a collection of problems associated with fossil fuels, there is a need to adopt alternative energy sources on a wider scale for the sustainability of the world population; a strong alternative is Nuclear energy. Particularly, the process of nuclear fission…

Uranium and its decay products can be found in the environment through a wide array of anthropogenic activities such as mining, nuclear and power generation industries and the production of phosphate fertilizers .(Sprynskyy et al. 2011) They pose a severe, long term ecological and public health threat (Khani 2011, Landa 2003) and therefore there is a considerable effort in the removal of these pollutants before their final discharge in the environment, as well as their recovery as an energy…

Mineral resources is a concentration of naturally occurring solid, liquid, or gaseous material in or on the earth’s crust that can be extracted and processed into useful materials at an affordable cost. Mineral resources are essential to support sustainable economic growth and our quality of life. Therefore, it is important to have sufficient supply of materials to provide for infrastructure, buildings, energy and goods. However, since mineral resources are nonrenewable natural resource, and…

Nuclear weapons were introduced into the world in 1945 ending the WW2. The main purpose of them was guised to “protect” the people of the world when it was truly created for another reason. We know what nuclear weapons can do, it has both short term effects and long term effects and also highly destructive, yet we still construct more of them. In total, there are about 23 000 nuclear weapons in the world (Walker, Countdown to Zero). Clearly, that is way too much weapons that cause mass…

million years old. Dating methods are used to find out about how old an artifact may be, or how old it is exactly. Relative dating methods are stratigraphy and style analysis. Absolute dating methods used are absolute dating, radiocarbon dating, uranium-lead dating, and luminescence dating. Stratigraphy as a dating method, is based around the principle that older artifacts are usually found below younger artifacts. When archaeological sites are excavated, the layers of ground near the…

Have you ever seen the picture that shows polar bears stuck on a small block of ice, embracing each other, and looking into the distant horizon, in hopes of finding the icy shore? If yes, that picture is the perfect reflection of the fate of all the animals that live in the North and South Pole. They face extinction because of the excess combustion of fossil fuels. Now what does combustion has to do with the extinction of these animals? Let’s start with the United States. For the year of 2014,…

A-10 proves it can land pretty much anywhere Since July 20th, four A-10s from the 354th Expeditionary Fighter Squadron of US Air force have practiced landing at an airfield that that has been decommissioned since 2000, near Nowe Miasto, in Poland. The cracked, crumbling runway is in bad shape from long lack of any maintenance, as the past Polish unit stationed there used helicopters, and conditions at the former Warsaw Pact airfield are poor in general. Not a problem for the A-10, which is…

The Gulf War, also called The Persian War, was in the frontlines of America’s news from the beginning of the war until the very end. This war took place 2 August 1990-28 February 1991. This war was fought between Iraq and 39 other nations including The United States, Great Britain, Egypt, France, and Saudi Arabia. This war lasted 6 months, 3 weeks, and 5 days. The Gulf War was fought in multiple different countries including Iraq, Kuwait, Saudi Arabia, and Israel. This war was fought to…

of the A-10 remains equipped with the biggest gun ever put into an aircraft. This wonderful piece of hardware is called the: GAU-8/A Avenger. It fires 30mm rounds that are either high explosive incendiary or an armor piercing incendiary with a depleted uranium core. To give you an idea of the size of this round imagine a glass soda bottle, it’s a little bigger than that. The weapon fires its rounds at a fixed rate of 3,900 rounds per minute and can fire about 18 seconds of ammo before running…
