Nuclear Power Essays (789 words) - Nuclear Technology,

Nuclear Power Nuclear Power Nuclear energy in California has produced 36,186 million Kilowatt/hours of electricity in 1995. The total dependable capacity of Californias nuclear-supplied power is 5,326 megawatts, including the two operating nuclear power plants in California and portions of nuclear plants in other states owned by California electric companies. There are two ways to release energy from nuclear reactions: fission and fusion of atomic nuclei. Electricity generating technologies are available, whereas fusion is still in the early stages of research and development. Nuclear fission is the process of splitting the nuclei of atoms, which releases energy from within those atoms. Nuclear fusion is the process of joining, rather than splitting, these atoms with similar releases of energy. There are several types of fission reactors in the United States but the most common is light water reactors. The reason they are called light water reactors is because normal (light) water is used to cool the reactor core; some reactors use heavy water, which contains hydrogen atoms with an additional neutron in the nucleus. Pressurized water reactors (PWR) and boiling water reactors (BWR) use uranium-235, a naturally occurring radioactive isotope of uranium, as a fuel. As the nucleus of a uranium-235 atom is hit by a neutron, it splits into smaller atoms of other elements, and releases energy and extra neutrons. Those neutrons hit more atoms of the original uranium-235 creating a fission chain reaction that releases more energy and neutrons. In a PWR, water passes through the nuclear core and is heated. The power plants primary circulating system passes water through the reactor core, where the water is heated by the nuclear reaction. That water (under high temp and pressure to prevent boiling) is passed through a steam generator, where it releases its heat to the secondary circulating system. Water in secondary circulating system is allowed to boil, and the resulting steam is used to drive a steam turbine-generator. In a BWR, there is no need for a steam generator and a secondary circulating system, as the water in primary circulating system is allowed to boil before exiting the reactor and is then routed directly to a steam turbine-generator. There are only two nuclear power plants out of six that are still used in California. The first one is owned by PG&E named Diablo Canyon Nuclear Power Plant near San Luis Obispo. The Plant has two units; the first unit is a 1,073-megawatt PWR, which began operation in May 1985. The second unit is 1,087-megawatt PWR, which began operation in March 1986. The second plant is owned by Southern California Edison Co. and San Diego Gas & Electric named San Onofre Nuclear Generating Station. Unit two of that station is a 1,070-megawatt PWR that began operation in August 1983, while unit three is a 1,080-megawatt PWR that began operation in April 1984.

There are many reasons and issues why we dont have a lot of nuclear power plants in California here are a few: ? Nuclear plants may not be economically feasible in the United States. No American utility has proposed to construct a new nuclear power plant since the late 1970s. ? Need for a spent fuel disposal facility and a decommissioning plan ? Use of large amounts of water for cooling purposes (if wet cooling ? towers are used) ? Biological impacts on the ocean due to thermal discharge (if seawater cooling is used) ? Designing for seismic safety ? Public safety concerns ? Transportation issues associated with the development of an emergency evacuation plan ? Changes in visual quality due to the power plant structures, including the reactor vessel containment structure, and cooling towers (if applicable) ? Potentially significant amounts of land ? Potentially significant public opposition Nuclear power plants produce a lot of energy but they serious environmental problems. I think that these plants are

The rebellion came about because the goldfield workers (known as 'diggers') conflicting the government miners' licenses. The licenses were a simple way for the government to tax the diggers. License fees had to be paid even if the digger couldn’t find any gold. They had to carry it with them at all times, or face a fine and arrest. Less successful diggers found it difficult to pay their license fees. The miners felt this was an unfair system and were prepared to fight for change. They lost the fight they were successful in bringing about the changes they wanted -miners paid a tax on gold they found, instead of paying for the possibility of getting gold. Many ordinary people hated the inequalities that existed between rich and poor in Britain and Europe. Australia seemed to offer them the chance to gain independence as small farmers. In the 1850s a popular movement developed calling for ‘free selection’. The first free selection Act was passed in the Victorian Parliament in 1860. In New South Wales free selection acts were passed in 1861 and similar laws were made in the other colonies. These free selection laws allowed

Construction Contracts Law Case Study Example | Topics and Well Written Essays - 2000 words

Construction Contracts Law - Case Study Example A proposal, when accepted, becomes a promise" Thus, when there is a proposal from one side and the acceptance of that proposal by the other side, it results in a promise. This promise from the two parties to one another is known as an agreement. Also all agreements are contracts if they are made by the free consent of parties competent to contract, for a lawful consideration and with a lawful object and are not hereby expressly declared to be void. These basic rules of offer, acceptance and invitation to treat etc are amply illustrated in the cases 'Pharmaceutical Society of Great Britain v. Boots Cash Chemicals Ltd.(1952)2 Q.B.795)' , 'Felthouse v. Bindley(1862)6L.T.157)' and also in 'Fisher v. Bell (1961) 1Q.B. 394)'. The intention to create a legal relationship is demonstrated by 'Rose and Frank Co. v. Crompton & Bros. Ltd.(1925)A.C.445)', Balfour v. Balfour(1919)2K.B.571)', By 'Jones v. Padavatton(1969)All E.R. 616)', and also through 'Merrit v. Merrit(1970)2All E.R.760)' As per the facts of the case it was a contract about the construction of a new warehouse incorporating high quality offices and the client wanted tight financial control. ... In nut shell the essentials needed for a valid contract, therefore, are as under : An agreement between the two parties. An agreement is the result of a proposal or an offer by one party followed by its acceptance by the other. Agreement should be between the parties who are competent to contract. There should be a lawful consideration and lawful object in respect of that agreement. There should be free consent of the parties, when they enter in to the agreement. The agreement must not be one, which has been expressly declared to be void. A proposal, when accepted, results in an agreement. It is only after the acceptance of the proposal that a contract between the two parties can arise. After the offer has been accepted, it becomes a promise which, if other conditions of a valid contract are satisfied, binds both the parties to the promise. These basic rules of offer, acceptance and invitation to treat etc are amply illustrated in the cases 'Pharmaceutical Society of Great Britain v. Boots Cash Chemicals Ltd.(1952)2 Q.B.795)' , 'Felthouse v. Bindley(1862)6L.T.157)' and also in 'Fisher v. Bell (1961) 1Q.B. 394)'.

Merrit(1970)2All E.R.760)' As per the facts of the case it was a contract about the construction of a new warehouse incorporating high quality offices and the client wanted tight financial control. There is no express condition laid down as to 'Time as the essence of the Contract' But through the wording of the contract it is quite clear that the client has laid down two conditions, first the quality of workmanship should

Fire and Emergency Management Research Paper Example | Topics and Well Written Essays - 3750 words

Fire and Emergency Management - Research Paper Example History There is a rich history that comes with the use of both the ISO grading system and the standards of coverage. The ISO grading system is actually adopted version of the fire suppression rating schedule (FSRS). The FSRS had been used as an independent rating system for several years in selected States until the need to ensuring that there is a global standardization of the activities of the fire and emergency service was brought up (ISO, 2014). Meanwhile, the insurance service office (ISO) had been functioning as an internationally recognized body that was responsible for setting standards of operation for various industries across the globe. To ensure that the rating schedule used for the purposes of fire and emergency fighting was at par with what was internationally recognized, the rating schedule was merged with the ISO standards to form what is today referred to as the ISO grading system of fire fighting. The history behind the standards of coverage can however be traced to very specific fire and emergency agencies across the country. This is because when the use of the standards of coverage started as an assessment system, it was only certified and used by the International Association of Fire Chiefs (IAFC). These fire chiefs were the ones who ensured that within the limit of the agencies that managed, there was a standard that defined the way they operated and responded to fire.

Emilia’s Perspective on Betrayal in Relationships in Shakespeare’s Othe

Emilia’s Perspective on Betrayal in Relationships in Shakespeare’s Othello In Othello, Act IV, scene ii and iii, Emilia, Iago’s wife, reveals her opinion about relationships to the reader as she attempts to comfort Desdemona. She indefinitely believes that many men, as well as women, are frequently guilty of deception and betrayal of their partner. By this part of the play, Othello’s suspicions of Desdemona’s unfaithfulness have greatly increased, and he begins to accuse her of cheating on him. When Desdemona persistently denies his accusations, Othello becomes enraged. He sarcastically asks for her pardon and claims that he took her to be the â€Å"cunning whore of Venice† (Act IV, scene ii, line 88). Desdemona is heartbroken by her husband’s mockery and seeks Emilia’s kind words. Emilia insists that female innocence and chastity is overrated when Desdemona scolds herself for her unworthiness of Othello. Emilia subtly suggests that Desdemona should leave Othello and seek happiness elsewhere. Emilia states in Act IV, scene iii, lines 83-85, â€Å"...’tis a wrong in your own world, and ...
