What is Nuclear energy: Definition and 55 Discussions

Nuclear energy policy is a national and international policy concerning some or all aspects of nuclear energy and the nuclear fuel cycle, such as uranium mining, ore concentration, conversion, enrichment for nuclear fuel, generating electricity by nuclear power, storing and reprocessing spent nuclear fuel, and disposal of radioactive waste.
Nuclear energy policies often include the regulation of energy use and standards relating to the nuclear fuel cycle. Other measures include efficiency standards, safety regulations, emission standards, fiscal policies, and legislation on energy trading, transport of nuclear waste and contaminated materials, and their storage. Governments might subsidize nuclear energy and arrange international treaties and trade agreements about the import and export of nuclear technology, electricity, nuclear waste, and uranium.
Since about 2001 the term nuclear renaissance has been used to refer to a possible nuclear power industry revival, but nuclear electricity generation in 2012 was at its lowest level since 1999.Following the March 2011 Fukushima I nuclear accidents, China, Germany, Switzerland, Israel, Malaysia, Thailand, United Kingdom, and the Philippines are reviewing their nuclear power programs. Indonesia and Vietnam still plan to build nuclear power plants. Thirty-one countries operate nuclear power stations, and there are a considerable number of new reactors being built in China, South Korea, India, and Russia. As of June 2011, countries such as Australia, Austria, Denmark, Greece, Ireland, Latvia, Lichtenstein, Luxembourg, Malta, Portugal, Israel, Malaysia, and Norway have no nuclear power stations and remain opposed to nuclear power.Since nuclear energy and nuclear weapons technologies are closely related, military aspirations can act as a factor in energy policy decisions. The fear of nuclear proliferation influences some international nuclear energy policies.

    News Should nuclear energy be phased out in the USA?

    Given the numerous externalities associated with nuclear energy including but not limited to Expense Safety Waste Disposal Vulnerability to Terrorist Attack perhaps it's time to reconsider whether we really need nuclear in the energy mix in the United States--and instead concentrate on other...

    Exploring the Energy-Mass Relationship in Nuclear Reactions

    The mass of an atom is less than the sum of its parts. The difference in mass is called the mass defect, and E = mc^2 shows how much energy that difference in mass has. Since mass and energy interchange in nuclear reactions, mass and energy would go on different sides of the equation. Here is...

    If you let go two oposite charges from distance D they will start to attract and if they can pass thru each other when they meet they will distant them selfs until they reach -D distance. They they will start geting back until they get to the initial distance D. This domain from D to -D via the...

    How Do You Calculate X-Ray Wavelength and Radioactive Decay?

    1. Calculate the wavelength of an x-ray which has a frequency of 10^16 Hz 2. Calculate the Energy associated with an x-ray with a frequency from Question 1. * I don't know how to do this, but from looking at the electromagnetic spectrum, it tells you. But i want to know how to calculate...
