Nuke Definition and 41 Threads

HI, Id like someone to assist me please. the nearest what I would consider nuclear target is 14.7km from my house as the crow flies. The presumed explosion is 800 kilotons air burst My house is brick built, modern double glazed windows. Diagonal on from the explosion. Nuke map indicates I...

Anyone been following this story? Sensational or did we really narrowly miss a global nuclear disaster? What were the possible consequences of the fire spreading to the reactor? https://www.bloomberg.com/news/articles/2019-07-08/stricken-russian-nuke-sub-crew-prevented-planetary-catastrophe

Sooner-or-later, at random, the world will be faced with the threat of a large Comet impact. Our only recourse will be to Nuke it. In order to know how large the thermonuclear device needs to be to either deflect or destroy it there are two questions: - What is the expansion velocity of...

This study from Johns Hopkins University shows that even if we manage to nuke an asteroid and "destroy" it, it will have a core back, in almost 2 hours. Nuking them was a bad idea before, but now seems worse. More details here...

So I was trying to debunk a conspiracy theory involving bombs and I realized that I have a small problem with Einstein's equation: E=mc2 To be honest I haven't really understood how it's used... I mean, how far should the fission go until as much energy as E=mc2 is released? Does the matter have...

Here is a longish article from Science mag news about using an agent based modeling approach and detailed geographic information to model what might happen if a small nuclear bomb went off in the middle of Washington DC. The article also discusses the use of similar models for other purposes...

Hi all, a 15 year old noob here. I want to calculate how much FORCE in NEWTONS would be delivered by a 100 kiloton nuke on an object of area around 2cm^2 from a distance of about 5 meters. This might sound like a stupid question, but all the answers about nukes are its POWER in joules, not...

Here is a Lawrence Livermore National Laboratory YouTube playlist of 64 recently declassified nuclear bomb test videos.

Hi all, thanks for allowing me on to your forum. I'm not a physicist, but I am trying to write a piece of fiction and I'm aiming to get my physics at least some what plausible, so I thought I'd ask the experts. It goes like this: A character in a novel I'm slaving on (set in the early 80s) is...

Helly everyone. I'm new in physics and I don't understand many things there. What interests me the most is energy generation. I was mostly reading Wiki articles, and I found something I couldn't understand, so I'm asking for help. According to wiki, peak power output of the largest nuke ever was...

If I major in math and minor in nuclear engineering. Can I work at a npp still? I would like to get a math degree rather than nuke degree just in case I want to work in the math field(no teaching).

Hey guys, I am currently working on a uni MATLAB group project for blast radius, thermal radius etc. Apparently these formula are the best possible to use: r_thermal = Y^0.41 * constant_th r_blast = Y^0.33 * constant_bl r_radiation = Y^0.19 * constant_rad But can anybody tell me what...

A friend of mine who is enlisting into the navy informed me of their enlisted nuke program. He really played it up saying I'd get great pay and a lot of benefits. I looked into it myself but found a large amount of people that were dissatisfied with their experience citing claims of delays of...

Okay can I first start of by saying sorry if there are any gramatical errors or mis-spellings I've got dyslexia and, well, sometimes things can get messy! So I have been really interested in Physics since I was really young, mainly in things like astrophysics and questioning why things happen...

Hey all, I graduated with a master's in Nuclear engineering last summer after I've spent the last 10 years working as an engineer in a totally different field. I have'nt had any bites for interviews, etc I was just wondering if maybe some of the working nuclear professionals on here might just...

Can you do nuclear physics research with a degree in nuclear engineering?

Could you stop an incoming nuke with an emp? Would it disable the nuke, or just detonate? Or even hav no effect, what would happen? Is there any other way you might stop an incoming nuke?

I'm suggesting to my nephew that he enlist and go for nuclear-qualified machinist mate position. I'd like to hear about post-Navy job opportunities in this field. Thanks.

Hello, I am studying Chemical Engineering at the University of Oklahoma. I have recently become very interested in Nuclear Engineering, but unfortunately my school does not offer the degree. Is it possible to go from a Chem E b.s to a Nuclear Masters? Thanks!

I found a recent article suggesting that solar storms predicted in in the next few years pose a serious threat to the electrical grid and thus to nuclear plant cooling systems: "Severe Solar Storms Could Disrupt Earth This Decade: NOAA," International Business Times...

Hello, So I have a problem in my last semester of my final year. There is a course conflict between two physics courses that I need to graduate: Special Relativity and Advanced Optics. The only reason is because I missed one course from the previous year and the undergraduate advisor said...

Ancient Greek over Modern Physics?? I'm a Math, Nuke E major Hi, This fall, I'm 3rd yr math major w/ a nuke E minor, & looking to get into grad school in Nuke E. It's alright if you say this is stupid, I merely want to know what you think. I plan to take ancient greek 101 over modern...

How is the net driving pressure difference within a PWR a function of T and H delta P = delta T(Core) * g * partial Rho(T, P(RCS))/partial T * delta H I get how this correlates to the pressure differential and is found with bernoulli's equation but how does the temperature dependence get...

So I was watching Abyss the other day and got to the part where Ed Harris drops down an underwater cliff to disable a nuke which lies at the bottom. I think the distance was two miles underwater. If the nuke were to have exploded what kind of damage would be done and would it have even been...

I'm not sure if this is the right spot for this question...if not could the mods move it please? If a nuke was used on the BP leak, would there be a chance that it could ignite the methane? I know there's lots of variables and factors but, if it was possible to ignite it, what's the chance...

Hey, I was just looking for people's feedback. I've completed a Bachelors in Engineering Physics (Canada) and a Masters in Subatomic Physics (France -research oriented, was originally leaning towards particle physics research not anymore). Needless to say theyres basically no nuclear jobs...

Will zero gravity effect the fission and fusion of the atoms making a chain reaction impossibile

There was no "Geology section" so I guess here is where this thread belongs. So, can a nuclear explosion blast one of the slopes of a volcano and open a gap through which lava will flow? Or will it be insufficient. By "nuke" I mean a bomb of ~20 kilotons, something between "Little Boy" and...

Wikipedia has an Ivy Mike level nuke at 530 TPa, and the core pressure is at 380 GPa. That's a factor of over 1000 times. I'm wondering whether these are exactly comparable, since the pressure at the core is constant, whereas in a nuke, it's relatively brief. A multi walled carbon nanotube...

Hi, A video link of the russian Tsar nuke being tested. http://www.break.com/index/russian-tsar-hydrogen-bomb-explosion.html Food for thought eh? wouldn't want one of those going off in a city near me. Utwig

"Aftermath: Population Zero" view of unattended nuke plants The National Geographic TV special called "Aftermath: Population Zero" explored the consequences if everyone on Earth vanished, particularly from the standpoint of suddenly unattended technical and industrial systems, and especially...

I just joined the Navy as a Nuclear Engineer. I was in college before majoring in Nanotechnology. I had failed calc III (lazy) and was feeling out of place. I had so many options in my face that I didn't feel like I could dedicate myself to something. I am fascinated in physics...

http://www.bangkokpost.com/breaking_news/breakingnews.php?id=124200 http://www.washingtonpost.com/wp-dyn/articles/A24677-2005Jan20.html Luckily, even Sen. Webb said that were Bush to bomb Iran, he would likely be impeached. Hopefully the fear mongering will end. Why anyone still believes...

Calls like this one to make international databases of nuclear "signatures" available publicly make sense to me as a way to help deter theft and transfer of nuclear materiel: http://www.nature.com/nature/journal/v443/n7114/full/443907a.html" The rationale is that a state that manufactured...

Ok, I was watching the movie "Resident Evil: The Apocalypse" the other day. The big evil "Umbrella Corporation" nukes a city to kill the T virus (which is what makes the people turn into zombies ) The cover up for the city getting vaporized is too just say that the local nuclear power plant...

Yah those are the last 4 words you want to see in the same sentence! http://www.msnbc.msn.com/id/10490469/ But it's ok, nothing bad happened... supposedly...

Im currently a Navy Fireman at NNPTC, I am already experiencing the school and getting by... but i wanted to know, what kind of out look I am looking for in the future as far as civilain job markets or staying in the navy... thanks

Ok I've done quite some reading on neutron bombs. What exactly is the difference between them in the way they work? The way i see it now its a nuke, but not focused on heat/blast damage but radiation. How does it work? Other material used? And what isn't really clear to me is if they have...

Did NASA Accidentally “Nuke” Jupiter? If you're not familiar with Richard Hoagland, famed for his claims of alien bases on the moon, Egyptian looking structures on Mars, and many familiar stories from the wild side, in fact, as I understand, he was once considered a highly respected scientist...

i was recently watching a TV program about british and norwegian soldiers who sabotaged a 'heavy water' factory in nazi norway in world war 2. it was said that hitler was trying to make a nuke and that this factory was vital to its completion. my question is, do you actually need deuterium to...
