THE NUCLEAR ARMS RACE The nuclear arms race began during World War II when the United States was informed that the Nazis may be building a weapon of mass destruction‚ the atom bomb. The US‚ realizing that the Nazis could possibly develop this weapon making them unstoppable‚ started its own nuclear weapons program‚ called the Manhattan Project. The US won the first nuclear arms race when they tested the first nuclear weapon on the Alamogordo Bombing Range in New Mexico on July 16‚ 1945. Only

Abstract Today‚ many safety-critical applications are controlled by computer software. Therefore effective testing tools are required to provide a high degree of safety and to reduce severe failures to a minimum. The paper examines existing regulating standards in safety-critical systems. By comparing different software testing methods the requirements and challenges in safety-critical software testing are being evaluated. The IEC61508 standard serves as the main regulatory framework for

Nuclear Energy – Blessing or Curse? Nowadays hot debates surround use of nuclear energy. It is widely suggested that it is one of the cheapest and cleanest energy resources‚ whereas others strongly disagree with that viewpoint‚ and claim that use of nuclear energy poses an unacceptable risk to the environment and to humanity. Consequently‚ there are many demonstrations against nuclear power plants worldwide‚ whereas others consistently support nuclear energy. Where does the truth lie? One of the

Advantages and disadvantages of Nuclear Power As an important part of science‚ at the moment‚ nuclear technology is being continually and effectively developed. Regarding to nuclear‚ there has always been controversies over whether its advantages outweigh its disadvantages. From my point of view‚ the matter of the use of nuclear power should be taken seriously and thought about carefully with positive attitude towards it. On the one hand‚ nuclear has been providing us with energy

Importance of Automobile Safety Many people‚ including college students‚ overlook one of the most important things when buying a new car–safety. It is a known truth that a new car is probably filled with the most up-to-date safety features in the automotive market today. However‚ knowing that the car is “safe” does not mean how safe the car really is because of the safety features it has or the lack of them. Therefore‚ this paper will illustrate the need to examine and research the safety features when a

Introduction In the development of next generation nuclear power plant‚ higher efficiency and more compact size of reactor core is important. Among the six next generation nuclear power plant‚ supercritical water-cooled reactor (SCWR) are promising because of their high thermal efficiency (i.e.‚ about 45% vs. about 33% efficiency for current Light Water Reactors‚

Nuclear energy is one of the hottest topics in the fight to a cleaner world. The number of people who believe that nuclear energy is too dangerous and unhealthy for the earth has skyrocketed because of the nuclear accidents that have happened in the past and recently. These protesters may have a lot of evidence and theories about how bad this type of energy can be‚ but the people who have realized that nuclear energy is the way to a cleaner and more “Green” society have proof and facts that overrule
