Kaplan University CJ340: Applied CJ Ethics Unit 4 Assignment August 26‚ 2013 Merriam-Webster’s dictionary defines “slippery slope” as a course of action that seems to lead inevitably to from one action or result to another unintended consequence (Merriem-Webster‚ 2013). The “slippery slope” can refer to almost every walk of live but here it is being applied to law enforcement and accepting gratuities. Here it is referring to police officers accepting what may seem to be harmless

Metals and alloys for nuclear energy There are two important ways in the making of nuclear energy: nuclear fission and nuclear fusion. Fusion and fission have a different working mechanisms‚ thus other materials are used. In a nuclear reactor fuel rods are bombarded with neutrons causing fission of the fuel. This way energy is released. With this energy water is heated to steam and with the use of heat exchangers and steam turbines electricity is generated. As fuel is usually uranium used‚ but also

Today‚ many countries are depending more and more on nuclear energy to produce electricity. Although‚ nuclear energy can bring many benefits‚ such as nuclear fission‚ which releases no carbon dioxide‚ it also brings many risks to many countries that use nuclear energy. This was proved‚ in many disasters that nuclear energy caused years ago‚ like the Chernobyl Disaster in April 26‚ 1986‚ which was said that‚ “the radiation released was to be 200 times that of Hiroshima and Nagasaki nuclear bombs

Nuclear Power Assignment -Containment structure: This is usually a big concrete dome or structure that protects workers and the area around it from potentially dangerous radiation. The walls of the structure are metres thick of concrete to absorb the radiation. -Reactor: The reactor is the most important part of the process as it produces heat which forms steam to power the turbines therefore creating electricity. It uses uranium-235 or in some cases plutonium-239. -Control rods: Control

Nuclear Power Stations 8.4.1: The firing of neutron at a heavy nucleus may result in the nucleus splitting‚ releasing free neutrons and lighter nuclei; which can then collide with other nuclei and resulting in the same process. This is a fission chain reaction. 8.4.2: In a fission reaction‚ if you can remove the emitted neutrons from the fissionable material‚ then you can control the rate at which the chain reaction proceeds. A fission reaction whereby the reaction is allowed to proceed without

nuclear weapon has been used in a conflict between nations. Fusion bombs‚ also called hydrogen or thermonuclear bombs‚ were developed and tested in the early 1950s‚ but these have never been used in warfare. A thermonuclear device depends on a fission reaction to produce extreme heat that causes hydrogen isotopes of deuterium and tritium to come together‚ or fuse‚ but the main energy source for thermonuclear devices comes from the fusion reaction‚ not the triggering fission reaction.

Helium-3 | General | Name‚ symbol | Helium-3‚ 3He‚ He-3‚3He | Neutrons | 1 | Protons | 2 | Helium-3 is sought for use in nuclear fusion. As we know‚ all nuclear power plants use a nuclear reaction to produce heat. This is used to turn water into steam that then drives a turbine to produce electricity. Current nuclear power plants have nuclear fission reactors in which uranium

NUCLEAR POWER Nuclear power is the use of nuclear reactions to generation heat and electricity. (U. S. Department of Energy and the Texas State Energy Conservation Office (SECO). July 2010). Through several processes‚ such as nuclear fission‚ nuclear fusion‚ or nuclear decay‚ energy can be produced. Humans‚ however‚ due to technological limitations‚ stick to the use of nuclear fission. Nuclear power today is a developing and important technology‚ and despite its environmental setbacks‚ it remains a source

Nuclear forces have a very short range (about one trillionth of a centimetre) but are comparatively strong (about one million times as strong as the electromagnetic forces between two masses). In both fission and fusion ‚ the total mass of the original nucleus or nuclei is greater than the total mass of the end products. According to Einstein’ s formula E=mc2‚ the energy

products; however‚ they do not make harmful effects of the nuclear energy. Another word for the LENR‚ as researchers named it: “cold fusion.” The scientists however‚ proved through experiments and theories that LENR is not “cold fusion‚” as the LENRs do not make long‚ lethal radiations. The practical definition of a LENR is that they are not based on any niche of fusion‚ but rather high‚ energetic reactions of nuclear that do not make any radioactive waste or radiation. The interesting fact of LENR
