Which problem is associated with energy produced by nuclear fission?
1. Some of the waste products from the spent fuel are very radioactive. 2. The plants are expensive to build, and to insure.
How many neutrons are there when uranium 235 is bombarded with a neutron?
When uranium-235 is bombarded with a neutron, it may undergo a fission reaction, resulting in the formation of multiple fission products, which may include different numbers of neutrons depending on the specific reaction that takes place. Typically, fission of uranium-235 produces around 2 to 3 neutrons per fission event.
How many neutrons are produced during a typical uranium fission reaction and what is the role of these neutrons in a nuclear chain reaction?
A typical uranium fission event produces 2 to 3 neutrons. These neutrons are moderated (slowed down) and go on to initiate the fission of more uranium. On average, in a controlled reaction that is maintained at normal criticality (KEffective = 1), each fission creates exactly one neutron that is used to produce another fission.
Is energy released from uranium 238 when the atom splits?
1. Energy (heat) 2. Fast neutrons 3. Fission products (atoms of other elements of lower atomic weight, often very radioactive). All three are produced simultaneously, for every fission that occurs.
Does uranium emit heat?
1. For the non-irradiated uranium the effect is unnoticed. 2. If you think to nuclear fission of uranium, this is another question.

What is the Fission equation of uranium-235?
U-235 splits into a variety of fission products, see the article linked below. Also 2 or 3 neutrons are ejected, with gamma radiation. The total energy per fission is about 200 MeV, or 3.2 x 10-13 Joules.
What are 3 examples of nuclear enegy?
1. Fission of uranium 235. 2. Fission of plutonium 239 . 3. Fusion of deuterium and tritium

What is uranium mass when it splits?
When uranium undergoes nuclear fission, its mass decreases slightly. This decrease in mass is converted into energy in accordance with Einstein's famous equation E=mc^2. The precise amount of mass lost during fission is dependent on the specific isotopes involved and the energy released.
Compared to the mass of a uranium nucleus before splitting the pieces it splits into have?
The mass of the uranium nucleus after splitting into two pieces is slightly less than the mass of the original uranium nucleus before splitting. This is due to the conversion of a small amount of mass into energy in accordance with Einstein's famous equation, E=mc^2.
Why don't the pellets with uranium oxide start to react during the enrichment process?
1. The material for enrichment is the uranium hexafluoride (UF6) not uranium dioxide pellets. 2. For a nuclear fission and and a nuclear chain reaction we need thermal neutrons.
Radiation is one of the long-term effects of a nuclear detonation wich of the fallowing type of radiation is emitted only during detonation?
Mostly Uranium 235, Uranium 238, and Plutonium 239 Also fission fragments. If your talking about any kind of radiation then it would be thermal radiation from the heat blast. When you split the Uranium atom you get 2 Neutrons, 2 protons + 2 fission fragments. 1 of the 2 neutrons will be uranium 235 and the other plutonium 239. the radiation from a nuclear blast will at first be heat. This will be continious until the energy that created it is depleated. Note Uranium 238 is weaker than Uranium 235 and it absorbs neutrons. Uranium 235 has a far greater Neutron density (99.3%) Uranium 238 = (0.7%)
What kind of bombs they had in the planes in world war 2?
High explosive (e.g. TNT, RDX, Amatol)Magnesium incendiaryPhosphorous incendiary1 Uranium gun fission bomb1 Plutonium implosion fission bomb
What is the 2 or more elements that make uranium?
Uranium is a chemical element and doesn't contain other elements,As all chemical elements uranium is formed from protons, neutrons and electrons.
