I'm going to be working on the lattice physics calculations using phoenix today and tomorrow.
I've noticed that SCWR's need a high number of groups for the calculations to be accurate. According to literature by Mori, an 11 group MGD calculation produced up to a 20% deviation in k effective...
Thank you for such a quick reply! I am designing a SCWR core for my senior design project. My professor keeps suggesting to see if a smaller version of the core can be produced, so that it can be built up (and transported easily) like the mpower reactor.
Based on your response I will read up...
Would it be possible to shrink down the scwr (super critical water reactor) to a modular size like the mpower reactor (such as the hyperion reactor)? Does anyone forsee any complications in this idea? It seems like the major change would be the use of super critical water. I know the SCWR is...
Talked to my professor again, he said that it is only true for scattering cross sections. If you look at the math, you will notice it is dependant upon the surface area. I'm guessing its some sort of quantumn mechanical phenomena?
My professor told me that the neutrons in a reactor see the surface area of nuclei, and not the the projected cross section. That really doesn't make intuitive sense. Is he right?
One of the thought experiments Einstein proposed involved one twin staying on earth, while the second twin entered a shuttle. The twin in the shuttle went on a trip (a physical one), traveling near the speed of light. The twin in the shuttle would have time pass by slower than the one on the...
For those interested, I found a good link on hyper-physics that seems to do a decent explanation:

After some Wiki-ing, I found out that all fermions are restricted by the Pauli exclusion priniciple. Do do the energy levels fill the same way as electrons (1s2,2s2,2p6 and so on)? And in what ways are these levels filled with protons and neutrons?
My professor mentioned that the pauli exclusion principle applies to the nucleus. How exactly is the nucleus quantized (the protons and neutrons), and how do the quantization rules apply to it (such as pauli's, hunds, and so on). Also, is this the reason why we don't observed multiple neutrons...
Well, i was under the assumption that the electron can exist in certain wave distributions according to the Schrodinger equation. Since it can't smoothly transition (or can it?), because its not a solution to the Schrodinger equation, it has to change its wave distribution instantly. So would...
What about when radio waves are created by radio towers? You need specific frequencies for the specific radio channels. How would they ensure that their radio wave is created at only the frequency they need? How does it correlate with the oscillating current?
I thought about the question some more and realized that if the current is high enough it will cause the free moving electrons to collide with the electrons in the stable atom and cause some of its electrons to be excited. Once these electrons de-excite, they can release visible light (or a...
