95 Nuclear Scientist Questions And Answers

62⟩ Tell me what Is Half Life And Its Significance?

The half life or half life period is defined as the time required for the radio-activity of an isotope to reduce to half of its original value. Radioactive material is dangerous because of its half life periods. Half life for radio active materials such as uranium, plutonium lasts for thousands of years.When the radio activity is exposed to the environment, the element will exist in the environment for thousands of years before it decays results in making the environment ( land, water, habitation ) radioactive for thousands of decades.

64⟩ Tell me where do you see the future of nuclear power in the next fifty years?

There is going to an enormous development in this field and in the Indian context also India has to become self reliant in the field of clean energy. And thet are new projects coming up for the purpose. But in next 50 years I see that about 25 to 50 percent of the energy distribution in India through nuclear processes only.

65⟩ Tell me what Is Nucleus?

It is the part of an atom where whole mass of the atom is assume to be concentrated.Or it is the central part of an atom which contain proton and nuetron.

67⟩ Tell me what Is Meant By The Rest Mass Energy Of An Electron?

According to the Einstein's Theory of Relativity, the mass of a body (say a particle) depends on the energy and on the momentum (say the velocity) with which the particle moves.

So, we have a problem: is there a mass value that every observers can relate to? Yes: is the rest mass, that is the mass you could measure in a frame of reference co-moving with the particle (in which the particle is still), that is the center-of-mass frame and that coincide with the minimum value measurable for every observers.

68⟩ Explain me are nuclear power plants worth the cost?

Nuclear power is expensive — really expensive. After reporting on the true costs of building and running nuclear power plants, Time magazine concluded: “It turns out that new plants would be not just extremely expensive but spectacularly expensive.” A report published by the Center for American Progress estimates costs for power from new nuclear plants to be 25 to 30 cents per kilowatt-hour–triple current U.S. electricity rates and 10 times the cost of energy efficiency. Wall street has largely deemed nuclear power a bad financial bet, with credit agencies such as Moody’s asking “whether new liquidity is even available to support such capital-intensive projects.” As a result Congress has been forced to dole out millions in loan guarantees in order to attract private financing for new nuclear plants. This is despite the fact that the Congressional Budget Office has concluded that the risk of default on a nuclear loan would be “very high – well above 50 percent.” Do we want to promote a energy “solution” that is more expansive and financially unstable — and creates fewer jobs — than renewable alternatives?

69⟩ Tell me what Is Fertile Material And Fissile Material?

Not all the Uranium extracted from the ore can be used as fuel for plant for carrying out the fission reaction. Natural uranium consists of 99.3% of 23892U and only 0.7% of 23592U. Out of these isotopes, 23592U is used in fission reaction

Materials such as 23392U, 23592U,and 23994Pu are called fissile material or fissionable materials. This material is required to carry out the fission reaction.

Materials such as 23892U and 23290Th which occur in nature are called fertile materials. Fissile materials (23392U, 23994Pu ) can also be artificially be produced using fertile materials.

71⟩ Do you know history Of Nuclear Reaction?

Bigger nucleus broken to from two lighter nucleus and two or three neutrons is called nuclear fission used for making atom bomb two ligther nucleus joined to form bigger nucleus is called nuclear fusion used for making hydrogen bomb.

72⟩ Explain why Is Heavy Water Used As A Moderator?

Heavy water is water highly enriched in the hydrogen isotope deuterium.we can compare the neutron inatractions with billiard ball collision, where neutron collids wth nucleus of other automs & lose energey. If the colliding nucleus size is small like hydrogen nucleus it will lose maximum energey. If nucleus is hevy the neutron hits the nucleus just changes its direction but not that much chnage in the energy of neutron. So we use heavy water as moderator to slow down neutrons.

73⟩ Tell me why is it so important to follow the details so precisely in nuclear energy?

Nuclear engineering is a dangerous technology. And technically if we see the anatomy of the reactions we can conclude that a very vast amount of energy is released in a very short time through a chain reaction and here we are only going to control that chain reaction . If we are not precise in our approach... It will lead to destruction. Nuclear plant will become an atom bomb.

76⟩ Tell me can extraction be made safe?

Millions of tons of toxic waste is created at the start of the “nuclear chain” with uranium extraction producing radioactive rock, dust and water — resulting in contaminated water supplies and skyrocketing cancer, kidney and other deadly diseases in communities near uranium mines. The extraction jobs are some of the most dangerous anywhere, with workers regularly overexposed to radiation. Is the human and environmental cost of uranium extraction being properly included on the cost side of nuclear power?

77⟩ Tell me why is nuclear power a great energy source? In your opinion?

We are getting too much dependent on fossil fuels. The oil prices are already high and also it is not convenient for the environment. Our major economy is dependent of coal but according to statistics it would require a million times less uranium than the coak to produce same amount of energy every year and that too without gren house emissions so nuclear technology is indeed a great source of energy.

78⟩ Do you know what Other Industries Have Adopted Similar Codes Of Conduct?

The process that produced the Principles of Conduct, as well as the Principles themselves, reflects a recent trend in the management of global challenges. Leading national and transnational industries [business sectors], such as the oil and gas, apparel and pharmaceutical industries, have come to recognize that their reputations as socially responsible actors are key to their long-term business success. Some industries with similar codes of conduct include:

☛ Manufacturing (The Fair Labor Association, Worldwide Responsible Apparel Production)

☛ Extractive (Voluntary Principles on Security and Human Rights, Extractive Industries Transparency Initiative, International Council on Mining and Metals)

☛ Financial (Equator Principles, UN Principles for Responsible Investment)

☛ Electronics (Electronic Industry Code of Conduct)

79⟩ Explain me can nuclear power production be kept safe from natural disasters?

Regardless of our best laid plans, tornadoes, earthquakes, tsunamis and other irrepressible natural forces will inevitably strike some nuclear power sites. Just this month a tornado forced the shutdown of the Fermi2 atomic reactor in Michigan, the site of a 1966 melt-down that nearly irradiated the entire Great Lakes region. We need to ask ourselves, is it possible to manage the risk posed by natural disaster?

80⟩ Tell me doesn’t Cheap Natural Gas Make Nuclear Uncompetitive?

Cheap gas is making coal, nuclear, renewables, and virtually all other energy technologies less competitive. But that didn’t happen by accident. The shale gas revolution, which dramatically lowered the price of gas in the United States, was made possible thanks to three decades of public investment in better drilling technologies. This is why investing in next generation nuclear technologies right now is so important. so that we have a new generation of cheap nuclear technologies that can replace fossil energy in the coming decades.
