What is Reactor physics: Definition and 25 Discussions
A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. As of early 2019, the IAEA reports there are 454 nuclear power reactors and 226 nuclear research reactors in operation around the world.
Dear experts, I would like to get help from you on something. I want to design a vver -1200 core in the serpent nuclear code, but I am getting errors in the geometry I defined below. I would like to get help from you on how to fix these errors.I seem to be getting errors in cell definitions and...
So I'm aware that uranium 235 is the fissile isotope which is used in fuel for most reactors (about 3% of all uranium fuel for example), but what actually happens to the other 97% of the U-238 if it doesn't undergo fission?
I get some of it absorbs neutrons making it U-239? But I've also seen...
I really like the book for how much it covers. There's not a single topic that's missed that is relevant to nuclear reactor design/analysis. Often other books can miss a topic or two. It's just that the style is not to the point and often time is wasted talking about things that are irrelevant...
Summary:: How do high-enriched uranium reactors compare with low-enriched uranium reactors?
Hello, I'm doing some research for a book, and there's some information about fission reactors I just can't find.
I am comparing HEU fission reactors with LEU fission reactors ... even ballpark figures...
How can we achieve "higher-resolution" 3D pin-by-pin core simulators "without spatial homogenization" for the nuclear reactor core (PWR/BWR) calculations? In regards to this question, is it okay to perform "pin-by-pin fine-mesh core calculation" and/or "cell-heterogeneous detailed transport...
Dear all,
I have completed my MSc and PhD in Nuclear Engineering (Reactor Physics and Core Design) from a UK university. I am currently working at a National Lab in France.
Can you please suggest/recommend me a site where I can find the most suitable jobs related to Nuclear...
I found this formula when I was studying neutron diffusion equation in Weston M. Stacey's book
Thanks in advance
cosβ=cosθx cosθ+sinθx sinθ cos(ψy−ψ)
Edited by moderator for clarity:
##\cos(\beta) = \cos(\theta_x)\cos(\theta) + \sin(\theta_x)\sin(\theta)\cos(\psi y - \psi)##
I have completed Calculus 1,2,3. I haven't yet completed differential equations.What other courses do I have to take to get started?
I know that there are difficult topics in reactor physics like neutron transport equation.So,it would be really helpful if you can give some guidelines so that I...
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.
Hey all,
Does anyone happen to know the value of ν∑f for natural uranium? Here ν is the average number of neutron released from fission and ∑f is the macroscopic fission cross section of uranium.

Hello hope someone can help me
I need to do WIMS reactor physics codes analysis for
1) divide fuel pin into radial equal-volume sub regions
2) preform criticality calculations to obtain radial fast and thermal neutron flux (use 0.615eV energy cut off between fast and thermal regions)
I will...
Hello,
I've heard that MCNP outputs delayed neutron fractions (beta) and neutron generation times (Lambda).
Any ideas as to where in the output file it writes these? I've coppied and pasted the Godiva reactor code and run it, but I can't seem to find it in there.
Best Regards,

Hi All Members
I've been lurking through the forum threads (as a guest) and I really enjoy the depth of discussions that arise, even to the most basic of questions.

Let us take the example of 89Y(n,n')89mY reaction. In the calculation of Q value we require mass of reactants and products. Both are same here. Then how to calculate the Q value of this reaction or how to calculate the threshold energy of this type of reactions?
The question of neutronics or reactor physics methods has come up at various times and with respect to different aspects. I thought it would be worthwhile to explore various methods, the technology and their applications.
Broadly, reactor physics calculations involve solving equations related...
Hey I am a math major looking to do an REU (and later a masters/PhD.) in nuclear engineering and I am interested in the field of reactor physics. I hear it tossed around a lot but I don't really know the definition of it. I'm taking a radiation physics class next semester at a separate...
nobody can solve my Nuclear Reactor Physics Question? please help me!
In the centre of the core of a 1000 MWe BWR, the observed fission rate is 1.7×1012 cm-3 s-1 and the observed temperature of the fuel is 800 oC. What will be the fission rate at the same location if the temperature is raised...
Why don't you answer my Nuclear Reactor Physics Qestions? ...Please Help me
[/B]1 ) Dry air at normal temperature and pressure has a mass density of 0.0012 g/cm3 with a mass fraction of oxygen of 0.23. What is the atom density of 18O?
2) In the centre of the core of a 1000 MWe BWR, the...
Hi
My school started a nuclear engineering concentration in the ME/CHE department for the spring and I just wanted to know what are the topics covered typically in a reactor course and what stuff should I brush up on to be sharp for the class?
Thanks in advance.
Hello everybody,
This problem is from "Elementary Introduction to Nuclear Reactor Physics" by Liverhant,
I will be thankful for any help,because I'm really stuck on it :(

Hi folks, can anyone suggest a good and current reference text on nuclear reactor theory and physics?
I'm a theorist, so mathematically sophisticated presentation is welcome.
Thanks in advance for any recommendations.
"nuclear reactor physics" by Weston Stacey
I just bought it and started reading it. Anybody know the book ? Opinions, remarks ? I might have a few questions when reading it, are some people prepared to discuss it ?
As a first question, actually, on the cross section plots, there's always...
