Thorium

Though the BN-800 is more costly than its light water counterparts, during operation, the reactor is known to be safer. The thorium reactor is still cooled with molten salt but has an emergency shutdown where the molten salt can be dumped into a reservoir chamber under the reactor, this allows it to cool down quickly enough to harden thus leaks are no longer a significant problem…

Nuclear Energy Nuclear Energy Nuclear Power Plants: Nuclear Power Plants are facilities which generate electricity through the use of nuclear reactions. It is referred to as a thermal power station because it creates a nuclear reaction, in which a lot of heat and energy is created. Due to the production of heat, the plan creates a lot of steam which is used like in coal or gas-fired power stations to drive turbine generators to generate electricity. Nuclear Reactions The are two nuclear…

Art, Ross, and Morrie have a model rocket club in which they are testing their new rocket, the Starstruck V. It fails (it EXPLODED). They get out of the makeshift house they constructed to hold the model rocket, when suddenly they see a man on the floor. He has blood on his head and there is also blood all over the place. The boys assume that a piece of the exploded rocket hit him on the head, and they call the ambulance. Suddenly, Art recognizes him as his uncle, Doctor Cargraves. Everyone is…

iron shell 56 miles thick. The crust has a thickness of about 43 miles on the moon's near-side hemisphere and 93 miles on the far-side. It is made of oxygen, silicon, magnesium, iron, calcium and aluminum, with small amounts of titanium, uranium, thorium, potassium and…

decay; write out the equation for the beta decay. U-238 has an extremely long half-life of 4.5 billion years. Using the isotopes from 3, what are the half lives of the 2 products. After 30 days, how many half lives have occurred? Given 85 grams of Thorium 234, how many grams will remain after 72.3…

Task 1: radioactive decay is a nuclei of some isotopes which are unstable. If a radioactive isotope decays the it will change and become a different atom with different number of protons. Radioactive decays also are a process which has an unstable atomic nucleus and which causes it to lose energy this because of radiation, for example there three main types of radioactive decay alpha, beta, and gamma particle. If a material has unstable nuclei it would be considered as radioactive. If an atom…

Radioisotopes are atoms that consist of unstable combination of neutrons and protons. All elements which have their atomic numbers greater than 83 are radioisotopes and have unstable, radioactive nuclei. They have at least one stable isotope and one unstable isotope. In order to gain stable conformation the nucleus of the atoms loses a neutron due to which radiation energy is given off and the atom is said to be in radioactive state. They are also called as radionuclides because they have more…

It occurs in three natural isotopes 2 19Rn (actinon), 220Rn (thoron), and 222Rn which is commonly referred to as radon. Thoron is produced in the thorium-232 decay series with its principle mode of decay being β (beta) particles. Actinon has a very short half-life of around 3 seconds and is only present in around 0.7% of natural uranium. 222Rn (radon) is the main radon isotope of concern. It occurs…

The Marble Institute of American notes, “All rocks have a small amount of radioactivity in them due to the presence of minerals containing the radioactive elements uranium, thorium and potassium. Because granite typically contains more of these elements than most other rocks, it will be more radioactive than a slate or marble, for instance.” The EPA also notes that porous stones such as sandstone are likely to emit more radon…
