if you go and watch the movie, the nuclear scientist there himself admits that this "melting down to the very core of the earth" is just a parallel, a metaphor, and that in reality the core would hit the ground water and explode into fume of radiation. so movie isnt really pushing this narrative

you are the nuclear Walter white

There is a licensed geological repository for transuranic waste, e.g., plutonium in Southeast New Mexico. Its radioactive materials license was issued by the EPA in 1999 and has been operating ever since. www.wipp.energy.gov/

I think I am learning Oilers identity

Where is that research?

Do u need enriched uranium to make plu like 3 or 5 percent or not

Awesome. But why normal reactors are not able to do this.

😮😎 🆒️

There's never been water on the planet since the beginning of time that has not been radioactive.

Having an alloy plug that melts at a precise temperature, and thus allows gravity to drain out the liquid reactant, is inherently safer than relying on mechanical control rods to try and prevent a runaway reactor. For this reason alone I believe that the liquid fuel type reactor should be given every chance to prove itself.

Nice explanation.

there are two benefits to thorium it hasnt been crippled by regulations yet, give it half a year of being viable its still a pipe dream allowing for lots of investor fellating into free money neither of wich gets power into the grid at any speed

Says the person who has _never_ drunk "zero" radioactivity water in their entire life. Nothing makes me angrier than flawed reasoning based on linear no-threshold modeling for harms caused by radiation or other contaminants. At some point, you have to consider the realities and practicalities of living in the actual world and recognize that we _must_ accept some reasonable threshold for purity (of anything), because the money it would take to lower it further would be better spent cleaning up some other substance we contact in our daily lives instead.

Shame more people don't see what you do.

If we radiant a none radioactive element like iron, will it turn into radioactive fissionable element?

Disagree with this completely…. Solid fuel reactors use highly pressurized water as a moderator to maintain fission.. Often thorium is suggested to be best used in a molten salt reactors, and the calculus completely changes with liquid fuel reactors. Graphite is the proposed moderator, so if you remove the liquid fuel from the graphite, fissioning eventually ends. It’s wayyyyyyy easier to remove a liquid fuel from a solid moderator. Plus this liquid fuel doesn’t need to be pressurized to maintain its liquid phase. All LWR use pressurized water which inherently creates the “boom” when mistakes happen. So it’s bananas to even try and compare the safety of these two designs as LWRs are wayyyyy more problematic because of their pressurized water.

I suspect that what the person in the original post refers to is exactly that there is no water in the molten salt thorium reactor typically favoured by thorium proponents. No water under some hundred atmospheres of pressure and a reaction that tends towards a temperature several hundred degrees lower than what is needed for a phase shift for the molten salt. No kaboom from water is what I suspect is referred to. Since that is the only kind of kaboom that has ever happened in a nuclear power plant. Just a guess of course.

This is one of the best advertisements for nuclear energy that I've come across.

One advantage of thorium based liquid salt reactors is supposedly that they can be used to burn up the plutonium and uranium that otherwise could be used to make bombs.

I am curious as to how accurate the values of half lives for different radioactive elements are. I can't think helping that something with a half life of hundreds of thousands of years would be difficult to measure precisely in 1 year. Are our instruments that precise?

Too many people have replaced faith in God with faith in science. The truth is that science doesn't explain nearly as much as people have been told and there is a fair amount of science that is wrong.

I worked at a Nuclear Plant and yes, their pretend safety efforts go to far. I witnessed the ridiculous red tape required to get anything done. But IMHO it was mostly for show, very little of the red tape actually made anything safer. It did however make Nuclear power more expensive than it needed to be.

We should just lock up retired power plants and walk away for a few decades while the radiation decays. Doesn't the radiation decay exponentially? Same with fuel, just park the casks full of spent fuel in a secure area. People get too emotionally irrational about radiation.

Mox fuel is a good thing period. It 100%cannot be used to make a nuclear weapon. Of course it could be made into a dirty bomb that just contaminates an area with radialogical material but thats true of any radiactive substance. The susquehanna nuclear plant is about 40 minutes from me and uses mox fuels

Shifty

@robertbhayes5039 id like to get your thoughts on a specific reactor design called the mker. It was a Soviet gen 3 graphite moderated reactor and the successor to the rbmk design. The mker was reportedly safer and more efficient than the rbmk

wow🎉😮

How about recycling nuclear waste to reduce the amount of time it has to be stored?

This is really a special case. The full equation is e^it = cos(t) + isin(t) ... just let t = pi to get the equation in the video. I think it is much cooler to let t = pi/4 and then you get e^{i pi/4} - sqrt(2)/2 * (1 + i) = 0. This allows the constant sqrt(2) be part of the fun. Side note, imaginary numbers are no less "real" that real numbers -- I have never stubbed my toe on the number 2.

Although there are countries that can and do build on time and on cost...

Perfect explain, thank you.

Cobalt-60: A Versatile Radioisotope Cobalt-60 is a radioactive isotope of cobalt. It's widely used in various industries due to its strong gamma radiation emission. Key Characteristics: * Half-life: Approximately 5.27 years. * Radiation type: Gamma rays. * Production: Produced in nuclear reactors by neutron bombardment of cobalt-59. Applications: * Medical: * Radiation therapy: Used to treat cancer by destroying tumor cells. * Sterilization: Used to sterilize medical equipment and pharmaceuticals. * Industrial: * Radiography: Used to inspect metal products for defects, such as cracks or corrosion. * Food preservation: Used to preserve food by killing harmful microorganisms. * Gauging: Used to measure the thickness of materials, such as paper and plastic. * Research: * Tracer studies: Used to track the movement of substances in biological and chemical processes. Safety Considerations: Cobalt-60 is a powerful radioactive source and requires careful handling and storage to prevent exposure. Proper shielding and protective equipment are essential when working with it. safety protocols: * Transport and Storage: Cobalt-60 sources are transported and stored in heavily shielded containers to minimize exposure. These containers are designed to withstand accidents and provide adequate protection during transportation. * Handling: When handling Cobalt-60 sources, personnel must wear protective clothing, including lead aprons and gloves, to shield themselves from radiation exposure. Remote handling tools are often used to minimize direct contact. * Radiation Monitoring: Regular radiation monitoring is essential to ensure that workers are not exposed to excessive levels of radiation. Dosimeters are worn to measure individual radiation exposure, and area monitors are used to monitor radiation levels in work areas. * Emergency Preparedness: Facilities that handle Cobalt-60 must have emergency plans in place to respond to accidents or spills. These plans should include procedures for containment, decontamination, and medical response. If you have any further questions about Cobalt-60 or its applications.

We are going to have to do something to charge all of theses EV. Our Government is spending $ on worse stupid crap.

If your SMR is a high-pressure/low-temperature power plant, you won't save a dime. If your SMR is a low-pressure/high-temperature power plant, you might save half or more but that's up to the regulator.

I guess the anti-nukers will have to be anti-hydro now as well.

Is that apply to nuclear weaponries too?

What up sir

Radioactivity levels and half-life are tied together. Thanks for pointing this out. Even just a couple decades in an interim storage system, the activity drops tremendously. Combined with a method of 'recycling/ burning' the transuranics makes the waste problem a whole lot smaller. I dare say disposal of many other man-made hazardous waste is a lot harder than this.

Unless, rather than trying to turn SNF into new light water reactor fuel, you just built fast reactors to use the SNF AS fuel, say in a molten salt fast reactor. Since we haven't yet built a single fast MSR, how about we try that?

"Dollar is king" It feels like we chose stupidity over common sense. Should I have hope that this will change anytime soon?

Where can I see longer lectures ? Thanks

THANKS! I was asking myself exactly that and this saves me a lot of reading! Wich I will do anyways!

Disassembled lol.

Could you please provide sources for this?

What do they have at the labs that they need security

No, idiot, they are "weed-out classes". You make these programs and majors unnecessarily exclusive based upon arbitrary measures to keep your little racket going. It's the most circular reasoning I have ever heard. "We define "quality" as passing these classes that we make arbitrarily hard and then claim the external validation is that everyone who has made it through our program based upon these arbitrary criteria is "high quality"". . . . .
