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.
Snns
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?
No
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
Register for classes I guess, sorry
THANKS! I was asking myself exactly that and this saves me a lot of reading! Wich I will do anyways!
Disassembled lol.
it may sound like an explosion, but it's not that. it's the same thing that happens to glass with a large rapid temperature change, same physics
Could you please provide sources for this?
What do they have at the labs that they need security
Classified tech
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"". . . . .

Its people you with half knowledge who confuse serious seekers of knowledge, who are sincerely trying to understand something .
3 mile island, fukushima...both US designed and built reactors. haven't heard of any Chinese reactors melting down yet.
On the chance that you might be interested to find out how recent research has shown anti nuclear narratives based on claims of excessive radiological risk are effectively founded on social myths, here is the paper: Hayes, R.B. Cleaner Energy Systems Vol 2, July 2022, 100009 Nuclear energy myths versus facts support its expanded use - a review doi.org/10.1016/j.cles.2022.100009 www.sciencedirect.com/science/article/pii/S2772783122000085
Wasn't one big improvement that they placed the reactor core below emergency cooling water tanks so that emergency cooling water could be gravity fed vs needing pumps?

Legacy material is the main source
@@robertbhayes5039 Interesting! So Legacy material is nuclear material that has already been used in weapons projects is that correct?

You can transport electricity through distilled water inside rubber tubes But I use magnets shaped like RPG shaped charges, and gold wires, to send plasma one way and contain it, and any extra current can go back into a battery. You can also add opposing electric currents to the magnets and wires, which articulates the tubes. Which look like tentacles, made of light. The tentacles can be connected to sensors, which allows an electric communication to be established with the fusion reactor. This can then be controlled remotely. I have seen this, and it had a battery on it. Looks pretty cool. Used to come out every night.
Perhaps because we now have 50+ years of hard data to show that nuclear is the safest. And the environmental extremists, by pushing CO2 as a pollutant made it harder for them to justify their opposition to nuclear since it is safer and cleaner than everything else.
If we dont stay ahead with fast breeder burning old waste and thorium cycle we will be left behind in the economic future. Government should nationalize energy and communication for the peoples benefit. Corporations have only suppressed emerging technologies for their own gain.🎉
We can't get people to trust vaccines. How are we going to get them to trust nuclear power? It won't be easy, but I'll make my next video about Nuclear Power. Good news: Congress passed a law to encourage building Nuclear Reactors (changing the mission of the NRC). We are building the Natrium Reactor in Wyoming. Even Oliver Stone now believes Nuclear is safe. I would love to hear your thoughts on the "Documentary" Netflix did on Three Mile Island.
It's just a matter of time before someone figures out how to manufacture gold, at an affordable price.
Dr. PAUL M BROWN showed another way. All elements have a fundamental frequency. If a inverse waveform at high enough amplitude will make the element stable again.
Ahhh... A sour grape. You had your chance back in the 1970s. You squandered it. Now, China is leaving you folks behind in the dust
China is doing pretty good for itself, considering its history, they should be commended for that
What scenario would we be storing nuclear waste in our house?
World’s most beautiful equation
And nature did it without casks, armed guards or even fences. A lesson to all the anti-nukers who immediately scream about nuclear waste.
Good point! Storeing used nuclear fuel is easy! Even rocks can do it!
Since. Thorium is already proven feasible.Anyone who supports nuclear must be invested You can do it right but you can't trust People nevada proves it poisoned aquafer

If, and its a big IF someone figures out a working MSR, molten salt reactor, then getting rid of uranium waste is a freebie. MSR's are based on thorium, but uranium waste is just fine too. MSR's date back the 1950's, the problem then as now is molten salt, extremely corrosive. Everybody and his dog is trying to figure out a a long lived material than will contain molten salt.
Chinese have more landers on the moon and built their own spacestation from scratch 😅 china supplies all the western modern technology like iphone and has more resources than USA
That's actually kind of cool. Did they come up with the tech themselves, or did they copy others?
In other words USA wants the cake and eat it and select who gets it
Sounds like the same thing all of the world powers want
Thorium is non fissile and cannot be used as nuclear fuel!!!! This guy is incorrect. You can turn it into Uranium 233 nuclear fuel but you need a nuclear reactor to do that and at that point you can just use plutonium breeder reactors which we already have. No one is going to put money to make thorium based nuclear fuel.
If We Did it, and made a Thorium Bomb, How effcient it will be?, how will be its range?, and what about the nuclear fallout?.
Yes it does but how much power can a car sized or engine size reactor yeild
