Can anyone give a percentage comparision of efficiency of energy conversion in nuclear fuel and fossil fuels like oil and coal?

Here's a simple article that presents the case that nuclear is actually a renewable resource. An excerpt: Any thoughts on the matter? Do other countries consider nuclear as renewable? Japan only comes to my mind.

Hi there, I'm looking for some interesting activities regarding nuclear physics in high school. I already have: - building a cloud chamber with dry ice or peltier modules - simulating radioactive decay with dice - simulating Rutherford's experiment hitting with glass marbles a hidden target...

What are some good ideas for a senior project in nuclear physics? So far I've taken the following courses (important ones): Analytical Mechanics, E&M, Introduction to Modern physics, Introduction to Nuclear physics. Right now I'm enrolled in the QM course (as well as others). I should be...

What's the smallest nuclear reactor possible in terms of size and/or weight? What kind of power output could it achieve?

Do they need a nuclear engineer in a Synchrotron ? if yes what kind of job does he do ?

Hi guys, I have been reading about nuclear fusion and I have some doubts that I did not find the answer. I understand that the reactants are in a more energetic state than the products when the energy release occurs, however: *What triggers the release of energy? *Where does the released energy...

If an enemy had a secret nuclear reactor and they were retrieving the rods, or whatever it is that they retrieve to make secret nuclear bombs, how much time (how fast) would it take for them to retrieve their needed material? Would just a part of the reactor be shut down, and if so, what...

Can anyone explain to me why angular momentum of F-19 equals to J=1/2, but if we calculate J with the shell model the result is J=5/2. Thank you

I've heard that the weak nuclear force is stronger than the electromagnetic force at distances of 10^-18 m. I've also heard that the strong force becomes repulsive at a distance of 0.7 fm. So if two quarks got to a distance of <<10^-18 m which force would win, the strong force or the weak force?

Good morning at all, I have to do one research of the transport of large nuclear reactors, and I need to have an idea of which is the DIAMETER, HEIGHT and WEIGHT of the reactor I think that there are a lot of different dimension, but i want to know only approximately, because i don't have...

Why do nuclear mass tables usually start with atomic numbers larger than 8? for example see following article: http://dx.doi.org/10.1016/j.adt.2017.05.001

Hi, Please could someone explain the differences between the strong interaction (force that hold nucleons together) and the strong force (force that holds quarks together) in terms of the exchange particles. I have been reading several online sources and there seems to be some disagreement...

So, I'm writing something taking place a few centuries after a global nuclear war, but I'm unsure what the climate would be like, both in general and in the story's specific setting - the western coast of Canada. Would the average temperature or amount of yearly rainfall change? Would areas...

Managed to get through a Ph.D. in nuclear physics without covering nuclear matter calculations (or I just don't recall it). My question is does nuclear matter have any shear strength, or is it like an ideal gas? What little I see of elementary calculations it's like a fermi gas so one would...

Homework Statement A neutron is passing through a thin sheet of 115In of thickness 0.01 cm. Given that the density of the sheet is 7.31 g cm-3 and that the absorption cross section is 100 barns, what is the chance of the neutron being absorbed? You may assume the neutron is not scattered. a)...

Could I please check if my answers to the following three questions are correct? My answers are in bold. 1. How would you expect 39Ca to decay? a) β+ or electron capture (EC) b) Electron capture only c) β- d) α 2. How would you expect 39Ar to decay? a) β+ or electron capture (EC) b) Electron...

Midland Nuclear Power Plant was going to have two nuclear reactors from Babcock & Wilcox. Unit 1 was to have a capacity of 460 MWe, while Unit 2 was to have a capacity of 808 MWe. Were the reactors twins that simply had different steam machinery due to the cogeneration requirements or were they...

I would like to know if there is any formula for calculating the necessary conditions for certain elements to undergo nuclear fusion. I know that before the quantum tunnel effect was proposed, theoretically nuclear fusion reactions shouldn't occur in the Sun; with the increasing energy (affected...

I've been reading about this a bit and stumbled across something that said its desirable that the heat source not be something that emits a lot of gamma radiation. Other than hazards to a technician, does this have any effect on the device its being used on? Why would it require extra shielding...

dear physicists is it possible to download full data of half lives (or another parameters) from Chart of Nuclides in http://www.nndc.bnl.gov/chart/ I can see data One by one for extract my Required data and it is too time consuming So, if there's any way I can download all the information, it...

I thought of another question(s) :) does temperature affect the rate of the decay at all? Does temperature effect the energy of the decay; in that the energy of the electron anti neutrino would be higher?

When two atoms undergo nuclear fusion, some of the mass is converted into energy, but where is this lost mass from? Atoms are composed of protons, neutrons, and electrons, but all three have all have set values for mass. What is the origin of this mass that is converted to energy?

In Wikipedia I read that Uranium-235 is a nuclear is fuel in fission reactors, also that Uranium-235 is split (fission) and energy is revealed. But in some images showing how nuclear reactors work, they show Uranium dioxide as nuclear fuel elements. In Wikipedia, it's written that the oxides...

Sorry, I have never found what does it mean Nuclear statistical equilibrium. It is used in any text but exact explanation nowhere. Please explain a physical meaning of it. Thank you.

hi dears first i hope that this is the right position to my topic I am a student and i want to know what is the future of nuclear physics researches and what if this field is still promising or not

Hi all , I have a very simple doubt in the basics of radioactivity . Nuclear fission is the splitting of the nucleus of a heavy atom such as U23592 by bombarding with slow neutrons into two lighter nuclei with a simultaneous release of huge amount of energy . Now my doubt is that - Can a...

In a heavy nucleus, the balance of the Coulomb and nuclear forces is a delicate one. This can be seen in two cases: First, in oblong deformed nuclei, alpha particle emission is more likely to occur at the poles, where the Coulomb barrier is thinner, than at the waist. Second, heavy synthetic...

Hi Sorry, English is not my first language. Is Turkey Point nuclear powerplant in Florida safe for the storm surge of Irma ?

Is it possible to bombard the reactors at the Fukushima power plant with alpha particles and or protons, and or neutrons and or electrons in a combination that would alter the radioactivity presently being admitted by the failed reactors

Is it possible to do masters in nuclear engineering with a physics degree

In a spectrum from an MCA (that is hooked up to a scintillator and PMT), does an increase in amplifier gain cause the peak to shift towards higher channels? I have a source and its really weak so while calibrating my detector, I had to turn the gain up way high to see a peak, but I'd preferably...

I am about to begin an MSc in Nuclear Engineering. I am competent in MatLab language but wish to practice/learn another in the time before my course starts. Would I be well served in continuing to practice MatLab or to learn another from scratch (C/Java/Labview)? Are there any particular areas...

It seems that the batteries installed at nuclear power plants would have been one of the largest scale applications of battery technology prior to the development of battery storage stations for utilities. I'm wondering what kind of technology they use(d) and what kind of lifespan, capacity, and...

The first light atomic nucleus with a second face Physicist found the first light atomic nucleus in a lab that had too little resources. http://sciencefeeds.weebly.com/journal/the-first-light-atomic-nucleus-with-a-second-face

I was unsure whether or not to post this question here or in the Nuclear physics sub-section, but it's a relatively simple question: Given that quantum tunneling exists, would it be possible to produce infinite energy via repeated nuclear fusion reactions? Now given the second law of...

Hello Physicsforums. The title states my main question, but there is a little bit more than is revealed there. 1. Can you become a nuclear physicist with a nuclear engineering PhD? 2. If not, then can I get a PhD in nuclear physics with a double major in mechanical engineering and mathematics...

Hello ,every one . I am a reactor physics　teacher . I want to find some books or papers about how to teaching reactor physics． if you know it ,please tell me. Thank you very much.

So I need some help verifying this information.(I had to dumb it down, for the younger ones) - The Nuclear Fission process is started when the Nuclear fuels rods are submerged in coolant water to moderate the Nuclear fission process. When the Fuel rods are put close together this sets of a...

Hi all, I'm currently a freshman studying mechanical engineering. My interest is 100% in energy production of all methods. However, I've wanted to work nuclear since I was 7 years old and intend to pursue higher degrees in it. I have chosen not to get my bachelor's in it as I feel a B.S. in nuke...

I understand that the difference in mass between the protons and neutrons and the nucleus itself is called the mass defect, and that this mass defect is converted into nuclear binding energy. What seems to confuse me is where this energy is actually stored. I've been reading 4-5 different...

Hi, does treating neutrons as waves make any difference when it comes to micro cross sections ? , does quantum mechanics help more than classical mechanics in nuclear reactor physics ? Noticing that I am a nuclear engineering student

Just wondering how much of this is political posturing and how much is hard science. http://www.sciencemag.org/news/2017/06/safety-problems-los-alamos-laboratory-delay-us-nuclear-warhead-testing-and-production

I've mentioned my admission to MS Nuclear Engineering in the University of Florida earlier. Thing is I am a foreigner. What with all the security most countries have surrounding nuclear technology, would I be limiting myself in the number of parties I can work with? I am aware I have other...

As a 14 year old, my access to resources is limited to what I can find on my phone or occasionally in the library. With this consideration, can anyone recommend some good online resource for learning quantum physics and nuclear physics. I already have the background knowledge, I understand...

ok , it might be a silly question .. but i just want to know how does the nuclear bomb react when her rockets touch the ground .. for sure the nuclear bomb isn't like the normal bomb or the dynamite that needs a spark to exploid ( excuse me I am not that good in physics :v )

When a proton strikes a target with high energy, neutrons are produced. Is the number of neutrons produced calculatable, or random? This reaction would be proton-target fusion, followed by fission. Is the fission random, or is there a way to calculate the average neutrons per reaction? If so...

I'm fairly new to nuclear engineering. Basically two questions regarding nuclear fission. 1) Neutrons hit atomic nuclei of fuel in reactor which in turn causes atoms to decay until a stable atomic isotope is ultimately reached. However, surely the "stable" isotopes (and also those unstable...

I am almost done with a BS in physics with focus in nuclear engineering and engineering. My classes have been all the normal BS physics classes as well as nuclear physics with kranes book, two classes with Lamarsh's books on nuclear engineering as well as the blue bible (deuterstadt and...
