E Correct answer
Explanation

E

The world Nuclear Association considers used fuel management to be sustainable if it meets certain criteria. The criteria includes the covering of all the steps of the used fuel management upto the final disposal with high feasibility. It must protect human health and environment without creating any impact for future generation.

Which weapons among the following, though, would produce far less radioactive fallout than current designs, although they would release huge numbers of neutrons?

  1. Pure fission weapons

  2. Boosted fission weapons

  3. Pure fusion weapons

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

C

A pure fusion weapon is a hypothetical hydrogen bomb design that does not need a fission primary explosive to ignite the fusion of deuterium and tritium, two heavy isotopes of hydrogen. Pure fusion weapons offer the possibility of generating very small nuclear yards and the advantage of reduced collateral damage stemming from fallout because these weapons would not create the highly radioactive byproduct associated with fission type weapons. These weapons would be lethal not only because of their explosive force, which could be large compared to bombs based on chemical explosives, but also because of the neutrons they generate.

Which of the following is true regarding the working process of weapon?

  1. Energy is released when those neutrons split off from the nucleus

  2. splitting the nuclei in the same way, releasing more energy and more neutrons.

  3. The splitting of atomic nuclei releases enormous energy

  4. None of the above
Reveal answer Fill a bubble to check yourself
A,B,C Correct answer
Explanation

A, B and C

Energy is released when those neutrons split off from the nucleus splitting nuclei in the same way, releasing more energy and more neutrons. The splitting of atomic nuclei releases enormous energy.

Hydrogen bomb is based on the principle of

  1. uncontrolled fusion reaction

  2. controlled fusion reaction

  3. uncontrolled fission reaction

  4. controlled fission reaction
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Uncontrolled fusion reaction 

Uncontrolled fusion reaction is the principle underlying hydrogen bomb. Basically in this process, lighter atoms will fuse or combine to form heavier elements.

In an atomic explosion, a temperature of about 10 million degrees is developed at the moment of explosion. The wavelengths of light corning from the hot region of the atomic explosion lie in the

  1. Ultraviolet region

  2. Visible region

  3. Infrared region

  4. X-ray region
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

lnfrared radiation, often abbreviated as IR, the large band of infrared wavelengths extends from the far-red portion of the visible light spectrum (around 700 - 780 nanometers) to about one millimeter in wavelength. This type of radiation is associated with the thermal region where visible light is not necessarily detectable or even present. As high temperature is developed at the moment of atomic explosion the wavelength of the light coming from that region lie in the infrared region.

Neutron ratio(r) (availability for fusion) of an atomic reactor and atom bomb are

  1. r > 1 in atomic reactor and r < 1 in bomb

  2. r= 1 in atomic reactor and r > 1 in bomb

  3. r > 1 in both atomic reactor and bomb

  4. r < 1 in both atomic reactor and bomb.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The reactor with conversion ratio greater than 1 is called a breeder reactor. This is the reactor that produces more fuel than it consumes. In atomic reactor Neutron ratio is greater than 1. 


A neutron bomb, officially defined as a type of enhanced radiation weapon, is a low yield thermonuclear weapon designed to maximize lethal neutron radiation in the immediate vicinity of the blast while minimizing the physical power of the blast itself. In bomb neutron ratio is less than 1.
