NSSC - Nuclear Science and Security Consortium
Добавлен 30 ноя 2015
The NSSC’s mission is to support the nation’s nuclear security agenda, recruiting and training students in relevant nuclear disciplines in preparation for research and leadership roles in the national laboratories. The NSSC draws students and scholars together in unconventional ways, replacing the boundaries that separate disciplines with a more inclusive science-technology policy interface.

Просмотров 1632 года назад
Advances in laser technology and plasma physics have allowed unique sources of x-rays, charged particles, and neutrons to be generated. The specific nature of a source may be tailored by careful consideration of the laser and target specifications, leading to a wide parameter space of possibility. In addition, working at the edge of what is achievable often results in large shot-to-shot fluctua...

The High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory is one of the highest flux reactor-based sources of neutrons for research in the world. The unique capabilities at HFIR are used to support missions in isotope production and materials irradiation. For example, isotopes are produced in-vessel for a variety of medical, industrial, and research purposes. Materials can be tested...

Gamma spectroscopy can be a useful method for non-destructive identification and characterization of nuclear or radioactive sources for emergency response, field measurements, and the laboratory. But often times analysis can be hampered by the availability or quality of analysis tools. InterSpec is an open-source (github.com/sandialabs/InterSpec/) peak- based gamma analysis tool that can be use...

The use of this lecture in a drinking game by anyone but the most professional and experienced drinkers is strongly not advised. Stamina is an absolute must to get through the first 10 minutes.
The Letter of Last Resort is still in use.
Ffs strategic means big boom, tactical means smaller boom. One meant to destroy city sized targets, one designed to destroy troops related to a fight in an area.
Was the FFTF reactor a breeder reactor?
It seems to me the beryllium reflector needs to be made in a way to crush the U239. Because the high explosives is in a shape charge it hits the beryllium reflector all the presser is pushing on the reflector and not the core. Therefor the reflector must be made to ratch down to a smaller sphere volume. That compresses of the U239. Also, this would help in the difference of time of the High explosive going off.
I've always problems with my designs. Whenever I crush the first stage into criticality, the corresponding chemical charges also destroy the shared casing with the second and third stage, but which is important as a radiation reflector to start the fusion, long before it could suit this role. I almost destroyed and irradiated seven livable planets now, but I don't come further. I've tried bigger casings, less tamper, even pits with extra layers and a floating core, to achieve criticality sooner. Do you have any tips for me please? Perhaps the Teller-Ulam design is a propaganda lie from the beginning and those bombs follow completely different principles? I've even tried to work around Pu239 and fission, using the intercept of potent pulse lasers to start the fusion. Please, I do not want to destroy and poison whole civilisations and biospheres.

What about Thermal Diffusion for the separation of Uranium 235 from 238??!!
Both USA and Japan built small scale thermal diffusion separation plants during the war, according to R. Rhodes. Not enough advantageous enough for USA relative to EM and gaseous diffusion.
@@vibrolax I guess you gotta try everything when you are the first to actually attempt the separation of uranium 235 from uranium 238... What I do remember reading about the gaseous diffusion plant... That while they were contracting it... The gaseous diffusion technology for it was still being developed in parallel! I guess given it was a war on, they didn't have the luxury of having to build a pilot plant first.... They had to build the production plan from the very beginning... And sort the problems out later... I don't think any building now would get an approval on that basis.....
@@vibrolax what was the principal behind thermal diffusion?

Teller was really smart. If I had built an exploding fusion factory, I would not be out to watch the event. You would find me also hiding in a basement far away ☀️... Not fun in the Sun.
There actually were 'wet' bombs designed and fielded as 'emergency capability weapons' based on the Mike design which used cryogenic Dewar flasks to store the fusion fuel.
couldn't they just take the flask turn it sideways and put it in a nuclear torpedo?
Tsar Bomba did something like this Tanks full of liquid deuterium and helium With a small atom bomb or trigger nuke
Wen ussr records propaganda of the internal construction
Americans figured by accident they can use lye drain unclogger instead so no need for high pressure cryogenic tanks

Question 1. On the plastic, is that expanded, or just solid plastic? Question 2. The mean path of a neutron, and the probability it hits a nucleus. If the metal is compressed and so the density rises, then the length available to hit a nucleus goes down, before it escapes. How does that interaction pay out with yield? I presume it reduces it. Question 3. With explosives, what increase in density can you achieve? Fat man, levitated pip etc, how does that work.
Compression improves yield, as the likelihood of hitting a target particle also increases as the size decreases. Additionally higher compression means you'll have more time to react as you pass into and out of the higher compression levels.
@@Nickle314 I think more than mfp the purpose of compression is to keep the geometry... I suspect the plastic as even being present in real device
Emmm, eh, urr, ahhh.

Back when those Iranian students were at MIT, Iran was one of the closest allies of the US in this region and also one of the largest buyer of US weapons exports. The whole Iranian military consisted of American equipment, even the civilian airline consisted of Boeings and McDonnell Douglas. They maybe checked if those students were communist sympathizers or had any ties to the Soviet Union. They did not understand, that you can be anti-communist, but also anti-american at the same time. Or those students turned to be more loyal towards political Islam after the Islamic revolution. Since Shia-Islam is almost exclusively a Persian thing, Persian nationalism and Shia-Islamism go well together. That was not understood back than.
Regarding the comment at 1:14:21 - the person who wrote that, and people like them, always seem to forget all the Japanese war crimes. They were not some cherubic nation going about their life when the US spontaneously decided to drop a nuclear weapon or two. Estimates of Japan's victims are in the millions but it's inconvenient to mention those when instead you could accuse the US of being racist.

Although I find any talks on these topics to be very interesting... this one is almost unlistenable with how much he says "um" "uh" "uhh" "um"... good information presented ... if you can break though the maddingly distracting ums and uhs... good god... I'll just read the transcript...
Next time find an actual physics lecturer - someone who can speak to an audience and hold its attention. If you take out all of the ummms, ahhhs, eerrrrrs from this video you might have a 5 minute short. I wanted to hear this information but the delivery was so gawd awful that I had to fold my tent and leave after less than 10 minutes. What was NSSC thinking?
2nd comment. 3 years on! I played it way back in 2019, but not many players on. Still the case in the present. And sadly the game had bugs. If they really wanted tons of data they could get heaps of people playing it which would give them tons of games worth of how people play. Risk is a great game as well. 9:30pm NZST 26 July 2022
I think Dr. Strangelove was a depiction of von Neumann.
23:00. Popular misconception. The primary and the sparkplug don't produce sufficient neutron flux to breed a meaningful number of Tritons. D-D ignition is initiated and it's its fusion neutrons that breed Tritium.
Don't they place tritium in the center of core... I have not seen the lecture just enjoying the comments so far😂😂😂
@mutiur7396 Yeah, gram quantities of a stoichiometric mixture of deuterium and tritium are injected into hollow cavities of the primary pit and secondary sparkplug, which undergoes fusion to boost the fission yields of those components. But those also don't produce enough neutrons to breed significant amounts of tritium from the lithium in the secondary...

Actually a very valuable lecture, and clearly presented. Thank-you Professor ! Little biased for Berkeley, and too few mentions of Col U or Chicago, but that is forgivable.
