95 Nuclear Scientist Questions And Answers

41⟩ What is Neutrino?

Neutrino is a small, tiny elementary particle which carries no electrical charge which means it is not affected by electro-magnetic forces, and travels almost the speed of light and passes through ordinary matter without making any interaction.

42⟩ Tell me doesn’t The Spread Of Nuclear Energy Increase The Risk Of Nuclear Proliferation?

There is no relationship between the global expansion of nuclear energy and nuclear proliferation.35 No nation has ever developed a weapon by first developing nuclear energy. To the degree that there has been a progression from one to the other, it has always been the opposite, with nations first developing weapons and then energy.

Some nations claimed to be developing nuclear energy capabilities when they were in fact attempting to develop a weapon,36 but these claims were transparently false to virtually all observers. By international law, nuclear energy facilities must be open to international inspections. The International Atomic Energy Agency has an extensive monitoring and inspection network, and it is not difficult to distinguish a weapons program from an energy program.

44⟩ Explain me how Is Energy Transformed In Windmills?

Essentially what happens is that as the energy from the wind rotates the vanes of the mill, coils of wire rotate inside a permanent magnet (generator) and produce electric voltage/current. This current is then sent onto the grid and used by us as electricity another form of energy. This is a very simple explanation and there is a lot more in the design of the system.

45⟩ Explain me me about a time when you made a mistake. How did you correct the mistake?

The biggest mistake I consider for myself was the time when I was in 3 rd year of my b. Tech course and I was coordinating the music team of IET luck now And I was organizing an event sur sangram but I did not made proper arrangement of the judges of the event. They felt very bad. I apologized to them but from Next time onward I myself checked that they don't face any situation like this again.

46⟩ Tell me what Is Fission And Fusion?

Fission: The breaking down of a Nucleus (not atom) into smaller nuclei. It is usually induced by a neutron.

For example, a Helium nucleus (called alpha particle) is divided into two 4He(+2) --> 2H(+1) + 2H(+1)

A lot of energy is released in the process.

Fusion: This happens when two nuclei combines to form a larger nuclei. Huge amount of energy is needed to start this. Because its not easy to bring two positively charged nuclei closer.When they combine, a huge amount of energy is released.

This usually happens in the stars. The enery required to start the fusion comes from the gravitational force between the particles.

47⟩ Explain how Has Atomic Energy Of Canada Limited (aecl) Become Candu Energy?

It has been a public policy objective of the Government of Canada for the last several years to transfer the commercial activities from AECL, which is owned by the Government of Canada, to the private sector. On June 29, 2011, the Government of Canada announced the signing an agreement for the sale of AECL’s Commercial Operations to Candu Energy Inc., a wholly owned subsidiary of SNC‐Lavalin. The targeted closing date for the transaction is September 30, 2011.

48⟩ Explain is It Possible That A Nucleus Has Negative Mass Defect?

If the nucleus has had a mass defect it is likely that the strong force and the weak force have sustained a major reduction in equilibrium. This can cause the positive and negative charges to reverse and change energy levels. Such a phenomenon has been describe by Einstein in his paper on the speed of light and time reduction. You can check this with the use of an electron microscope to determine is the color spectrum had changed drastically. If so, then you may have a problem.

49⟩ Tell me do we want to switch to nuclear power when there is ZERO room for error?

BP official Mark Hafle recently told a Coast Guard investigative panel that “all the risks had been addressed” at the Deepwater well. With oil still gushing, he’s clearly untethered from reality, but it raises an important question: While we can force BP and other oil companies to improve their safety and environmental damage plans, are there are some technological systems — like nuclear power and deepwater drilling — that are so dangerous that they are unacceptable unless they have zero possibility for error. And who could ever give such a guarantee? If we build the thousands of nuclear plants required to meet growing energy needs, even the smallest mistake puts millions of lives at risk. As a society are we willing to accept the risk — however small — of such a catastrophic disaster?

50⟩ Explain me what Was The Process For Drafting The Principles?

Carnegie began this process by convening the leading international experts on various aspects of nuclear power plant exportation as well as key exporting vendors of nuclear power plants. Drafting took place at a series of meetings occurring every 3-4 months.

These meetings brought together Carnegie staff, the participating vendor companies, and a group of international experts on the subjects addressed in each of the Principles, as well as antitrust/competition law counsel. The meetings, which were held over a three-year period, involved discussion of the substance of Principles as well as the crafting of consensus on the text of the Principles themselves.

51⟩ Tell me what Is The Difference Between Cathode Ray And Beta Ray?

Actually normal on the wave front called RAY, in the beta radiation there is wave packet and hence no wave frant. in cathod ray there is electromegnatic radiation and we can use word ray but in the case of beta partical we use word beta radiation instead of betaray.

53⟩ Tell me do We Really Need Nuclear In Order To Deal With Global Warming?

Preventing dangerous warming of the planet due to human emissions of greenhouse gases will require that we cut our emissions by 80 percent over the next 40 years at the same time that global energy demand is expected to double or triple. Doing so will require that we produce vast amounts of zero carbon energy. At present, the only way we know how to do that is with nuclear energy.

54⟩ Tell me what About The Risk That Terrorists Will Attack A Nuclear Plant?

Nuclear plants are not good targets for terrorists. The plants have high security, extensive perimeters, and are built to withstand the impact of a plane crash or large explosion. Were terrorists somehow able to infiltrate a plant and escape undetected with fuel or waste—a highly improbable scenario—they would still need costly, difficult to obtain equipment and highly sophisticated technical knowledge to turn the material into a weapon. It has taken decades and billions of dollars for nations like India, Pakistan, North Korea, and Iran to build a single bomb. The prospect of non-state actors marshaling the technical and financial resources to do the same is highly unlikely.

56⟩ What is Pascal law?

A Pascal law states that when you apply force at one point on liquid it will transmit equal force from one location to another within the liquid.

60⟩ What is dyne?

Dyne is a unit of force or also referred as C-G-S (centimetre – gram –-second). It means that when a force is applied to mass of 1 gram, it gives acceleration of 1 centimetre per second.
