Hello, I am doing a small research investigation into whether Nuclear Fusion will provide a safer and as efficient energy source as current Fission technology. Just interested if anybody has opinions on the topic and what their stance is on Nuclear Fusion, do they think it can work, any...

How much energy does a neutron need to be able to split an atom and start nuclear fission?

Hello, I have been really interested in nuclear fission in my life, however, have not studied anything solid in the field. I have, however, read a little about it. Basically, I know that in order for fission to take place, a neurton needs to collide with a large, dense nucleus. What I do not...

Is there any possible way to extract energy that isn't in terms of heat in a nuclear reaction? It seems like a very passive way to collect energy. There are many medium transports from the reactor to the actual steam turbine (e.g. supercritical water, molten sodium, etc). Is there any proposed...

The binding energy per nucleon of each nucleus is as follows. 235 U : 1.2191 x 10^-12 J 92144 Ba : 1.3341 x 10^-12 J 5690 Kr : 1.3864 x 10^-12 J 36Use the data to calculate 1/ The energy release in this fission reaction( give your answer to 3 significant figures)The answer to the...

Homework Statement For my essay on nuclear fission and fusion, I have to discuss some experimental evidence for nuclear fusion. I also need to find info about scientist that are responsible for developing the theory behind nuclear fusion. I am having trouble find info on these aspect. Any...

Homework Statement Example nuclear fission: {}_{92}^{235}U+{}_{0}^{1}n \rightarrow {}_{38}^{90}Sr+{}_{54}^{163}Xe+10{}_{0}^{1}n+Q How much energy does such fission release? Homework Equations I'm given the values of M({}^{235}U), m_{n}, M({}^{90}Sr), M({}^{136}Xe) but I've not...

Looking at the fission of Uranium 235, the typical end product will be Barium 141 and Krypton 92, and 3 neutrons. From this, we can calculate the energy that the fission gives off, by taking the difference in mass of the product and "reactant", and use the equation of E=mc2. But what i see...

1. What is the energy released in the fission reaction 10n + 23592U --> 14156Ba + 9236Kr + 310n? 2. I am pretty sure this has to do with binding energies, but other than that I'm completely lost. Please help. Thank you so much.

Is it possible to use fisssion to create plasmas, then use the plasma to generate electricity instead of suing steam to for elctricity? Just a thought.

Energy Principle and Nuclear Fission Rhenium HELP! ASAP Homework Statement For some isotopes of some very heavy nuclei, including nuclei of thorium, uranium, and plutonium, the nucleus will fission (split apart) when it absorbs a slow-moving neutron. Thorium-227, with 90 protons and 137...

I'm looking for the most common thermal fission products for U-233, U-235, Pu-239 and Pu-241. As far as I understand it there are two quantities of interest, the cumulative fission yield and the independent fission yield. The latter being "number of atoms of a specific nuclide produced...

Homework Statement How many kilograms of U-235 would be needed to run a 707 MW reactor for 1 year? Homework Equations 183.9 MeV released per reaction 7.57E26 reactions per year (These numbers are from the prior problems) The Attempt at a Solution I thought maybe half life, but...

If anyone can help me with this question I'd be greatly appreciative... Here's what I think I understand: Nuclear fission is the breaking of an atomic core of an atom. Like with U-235. It absorbs a slow moving neutron which yields the unstable U-236. Because of the instability the atomic...

The nuclear fission does not work! No infraction please! I was perhaps mistakenly under the impression that matter was destroyed in nuclear fission, but a careful look at this diagram (top right) appears to show all the protons, neutrons and electrons are balanced in the equation...

1. Homework Statement [/b] The overall question is: For this assignment explain how the E=mc2 equation applies to nuclear fission. In your answer illustrate your explanation with an example, being sure to distinguish between mass and mass number, and explain how a nuclear equation differs...

I am trying to come up with an example to illustrate how E=mc2 applies to nuclear fission. I need to be sure to distinguish between mass and mass number. I feel like I have some thing on the brink of my mind and then I loose it. I guess I need some help as I am tired and don’t know how much...

What nuclear fission reactor design has the least environmental impact? Including the building, operating, safety, and amount of pollution produced? I'd imagine IFR/breeder reactors as they burn actinides.

hi guys, iam kinda stuck on 2 problems. here is what it is : The nuclear fission reaction of uranium-235 with one neutron produces germanium-81, 5 neutrons and another element, what element is that? what's the atomic number andatmoic mass,?give the equation. 2. how much energy is...

uranium is f-block element..is there any relation between f-block elements and nuclear fuel...what i mean is ,i think f-block elements have more probablity of becoming nuclear fuel..is this correct?..

i have some basic doubts...why is that nuclear fission is done only on heavy nucleus..what stops to perform nuclear fission on lighter nucleus..what are the lighter nucleus that are used for fission if any?

[SOLVED] Nuclear fission and amount of U-235 used Homework Statement At the fission of a U-235 atom about 200 MeV of energy is released. How many fissions occur in 1 second in an power plant which has the heat energy capacity of 2050 MW? How much U-235 is consumed in one year (330 days)...

Homework Statement If Bill put enough radioactive matter in one place, the chain reaction associated with multiple radioactive decays can be made to run out of control and will form an atomic bomb. What do we call this amount of matter? Homework Equations The Attempt at a Solution

in nuclear fusion, 2 nuclei join to make one correct, therefore there is a loss of mass and energy, that energy escapes as gamma rays etc. but in nuclear fission, as the binding energy increases surely energy must have to come from somewhere, but apparently energy is given out? also my...

Esp given that most of the energy has yet to be tapped

Hi, I am studying in 10th Standard and preparing for final exams, anyone please help for this following question. When Uranium undergoes Nuclear Fission, 0.1 %(percentage) of total mass is converted into energy. Calculate tota amount of energy in Joules during an explosion of atom bomb...

I can't quite understand critical mass. They say in a fission bomb they have to separate two blocks of fissile Uranium of subcritical mass so they won't undergo spontaneous fission. What exactly is critical mass? Is it just the amount of Uranium held in one place at one time and if so why...

Homework Statement 1. Which of the following statements is / are not correct? (1) In fission, two large fragments of equal masses are produced from a nuclide. (2) Natually occurring elements perform fission spontaneously. (3) 2 H2O --> 2H2 + O2 involves nuclear fission. Homework...

I am new to nuclear. you could answer me one question : why do people say "fission", I thank you

hey need to write a paper on the advantages and disadvantages of nuclear fission.. this is briefly what i have come up with: Advantages: 1) Nuclear Power: efficient and a good alternative to coal which is exhaustible.. Disadvantages: 1) It resulted in the development of atomic...

This is probably an easy question for most of you, but me nor my teacher knew. Today we learned that nuclear fission can occur when a neutron "hits" the nucleus of Uranium-235. What i wanted to know is, where does this neutron come from, and how can they make it hit this uranium-235 atom. Any...

"nuclear" fission produces quark mass A top quark is roughly 32 times more massive than a bottom quark. A charm quark is roughly 8 times more massive than a strange quark. And a down quark is roughly 2 times more massive than an up quark. In nuclear fission 2 neutrons yield 4 neutrons...

Hi, just unsure about a question I wonder if you can help me with: How do the neutrons released after nuclear fission differ from those absorbed to begin the reaction in the first place. I think this may be asking me about delayed neutrons, but this is more to do with how the neutrons are made...
