Why can't the Sun (or any star) fuse elements higher than iron? Could anyone provide a technical answer? Thanks!

I've heard this expression in nuclear physics: the "island of stability." I know it has to do with the stability of a heavy transuranium atom (at least i think so), but what precisely does that expression mean? And what does it have to do with quantum mechanics? Why is this "island" there...

i want to become the physicist behind nuclear engineering or electrical engineering i want to study how particles and electrons work , how the nucleus work , but still i don't want to become someone studying something that has nothing to do with reality or someone who just applies knowledge...

I am an aeronautical engineer and I am curious why do NE's design the reactor smokestacks to be shaped like elongated rocket nozzles? In general, the nozzle shape offers less drag and a cleaner exit of the flow upstream and downstream from the nozzle exit. In supersonic flow, the nozzle shape is...

Do nuclear plants shut down during a tornado warning? I have heard that they do but really can't think why.

Hi all, just to point out that I am a lay person as far as physics go, but thought that perhaps someone here can help me! While in St. Petersburg recently I went to a flea market and purchased the ship's compass from a Soviet Submarine. Not exactly sure from which sub or when it was built...

I am confused about spontaneous fission. My basic understanding is that like α-decay the tunnel effect is responsible. We have a potential barrier caused by the superposition of surface tension energy and coulomb potential through which an energised nuclear fragment can tunnel with a certain...

Hello everybody! :wink: I have some difficulties concerning the concept of nuclear binding energy. First, look at this example: http://www.freeimagehosting.net/newuploads/jtefo.png In the first case, the two protons have big energy. But this energy is not changing it's weight. And in the...

I'm in undergrad doing research with a professor. He's leaving for vacation for a few weeks, and has tasked me with a project. I've been analyzing some spectra for some Carbon reactions, and he posed a question to me on why we don't see other higher-energy states, even if the experiment is ran...

What are your thoughts on nuclear energy ? Are you for it or against? In my opinion the only cons are that fact that they cost large amounts to build/maintain, as well as they develop radioactive waste. But the waste can be dealt with, thing plants can power entire cities while a regular...

Hello, My name is Zack Groothouse. I am new to this forum, although i have read the forum rules, please forgive me for any rules i break, or mistakes i make in my statements. I just recently graduated high school (2 weeks ago to be exact) and I am aspiring to be a nuclear engineer. I would...

is it possible to make a nuclear "battery" which works off nuclear not electrochemical reactions using berylium/graphite shielding?

When a nuclear reactor is in a critical state, the neutrons released in each fission trigger an average of exactly one additional fission. If the average number of additional fissions triggered rises above one, the reactor enters a supercritical state in which the fission rate and the thermal...

I know people have designed nuclear rocket engines, but is there any reason you couldn't have a nuclear thermal jet engine? Simply take a conventional jet and swap out the combustion area with a small reactor? Could the same idea work at higher speeds with a nuclear ramjet, or scramjet equivalent?

Do you think it would be possible to use a beam of neutrinos to probe the structure of atomic nuclei? Since they do not interact electronically, they would be useful to study the structure of both neutrons and protons, either through gravitational deflection or weak interactions. Could this...
