Why Nuclear Power Station Is Better than Normal Power Station in Essay

Why Nuclear Power Station Is Better than Normal Power Station in Generating Electricity - Essay Example Introduction: This project is about nuclear energy and how important it is in our life as a source of energy that can be produced in nuclear reactor. Nuclear reactor can produce a high amount of energy which can use to boil water in order to produce a high amount of steam which helps to generate electricity. Nuclear power station is an efficient source of energy that can produce a huge amount of electricity and relatively cheaper than the other source of energy; able to reduce the emission of greenhouse gases which play an important role in changing the environment; and has a high level of safety equipment to monitor and prevent any error or failure. Therefore, relaying on nuclear may change the future of the world and the future of our new generation. Advanced methods are employed to make nuclear power safer and more cost efficient. The advanced ABWR (Advanced boiling water reactor) and PWR (Pressurized water reactor) techniques have made the nuclear power much cost efficient. The a dvanced core cooling techniques made nuclear power safer for the future. Now a day our major problem is the green house gases emissions and to address the problem nuclear power has a better and safe solution. Nuclear power is free from green house gases emissions. ... In comparison, one kilogram of uranium releases almost the same energy produce by 1 million kilogram of coal (Dittmar, 2009). This energy release because the atom in nucleus split into two fragments and the two fragments split into four and then four to eight and thus a chain reaction starts. At every split, a large amount of thermal energy is released, which is used to heat water to generate power. This is all that happens in all nuclear reactors to produce that huge amount of energy. The capital investment that is required in building a nuclear power plant is comparatively higher than other power plants but the operating cost of a nuclear power plant is lower than a conventional coal or gas fired power plants. Secondly, using nuclear energy as an alternative source of energy will reduce the amount that spent in producing electricity by using fossil fuel. The cost of nuclear fuel is comparatively low as compared coal or gas in terms of energy released. However, there is misunderstan ding between the cost of nuclear energy production and the cost of producing nuclear as station that include a high safety level and materials use to control it outcome disposal. The cost of any nuclear power plant is highly dependent on the structure, locality and cooling techniques utilized to remove the unnecessary heat or decay heat. Decay heat or unnecessary heat produced by a nuclear reactor is a big problem and it should be taken care of. Pumping cool water through the nuclear reactor helps remove the decay heat. A structure that could hold a lot of water like a lake should be built before or after constructing a nuclear power plant. If a power plant is near a natural source of water,

Temporary agencies in organisation Essay Example | Topics and Well Written Essays - 1000 words

Temporary agencies in organisation - Essay Example Generally, client organizations divide its workforce between core and peripherals. Core workforces are derived within the organization, while peripherals are obtained outside the organization. Literature indicates those firms are responsible in making the decision on the jobs that should be retained for the permanent employees and tasks to outsource (Booth, Francesconi and Frank, 2002). Outsourced tasks require less organizations skills and knowledge such as routine. Based on this model, firms distinguish core labour in order to reduce turnover of skilled workers. In other words, the addition of the temporary agency staff in a firm helps to make quicker adjustments of the number of staffs when need arises. Therefore, during economic contraction, firms hire the temporary agency workers. The firm will no longer have the need to sack the permanent members of the workforce (Forde, 2000). In addition, the firm may opt to use temporary staffing agencies to reduce the increasing labour costs. Research indicates that most temporary agency workers receive less pay compared to the permanent members of the workforce (Booth, Francesconi and Frank, 2002). However, this may differ between the bottom and top end of the labour market. In addition, firms are able to reduce operation costs by reducing liabilities such as holiday pay sick pay and maternity cover, although this may differ in various countries. In some countries, the temporary agency workers are entitled for payments. Moreover, the use of the temporary agency workers reduces the fixed cost of hiring permanent staffs. Outsourcing some functions allows a firm to reduce their non-core proficiencies. Therefore, the firm has more time to focus on its main functions. The client organizations get opportunity for screening the temporary workers for potential permanent employees at low cost. Hiring core workforce from a pool of temporary staff can be
