Why BWR are the future of Nuclear reactors

Hey Friends, this video is part of a series where I explained every single GEN II nuclear power reactor design. Boiling water reactors are a Generation II nuclear power reactor design which were developed and founded by General electric and the Argonne National labs. These reactors are relevant to this day. Exciting advancements are being made currently with the BWRX-300 small modular reactor by GE Hitachi Nuclear Energy

Years ago I used to work at a BWR-3 (Not Fukushima). Toward the end of the video, Mr. Baig discusses Boron. Whilst walking through the power plant, I recall my associate telling me that whatever you do, don't kick that valve. I asked why. He explained that the valve will "poison" the reactor with Sodium Pentaborate. Apparently, it was one of many safety features. I didn't kick it.

One big advantage of the BWR is their contol scheme, which allow for load following way better than most other nuclear units. Using steam voids and jet pumps they can move from 50% to 100% in 3+ hours. The power grid needs power plants with flexiblity like these. I'm happy to finially see a BWR in the SMR mix for this reason. The BWRX-300. Good video Osama!

[davidanderson]

Nice video. I'd love to see a followup on the ESBWR and BWRX-300, since the BWRX-300 is likely to actually get built, including in Canada.

[SonyaFink]

Have you done a video on Darlington's planned BWRX-300? I think OPG is tagging it as Gen 3+ since it's not as advanced as currently out-of-reach Gen 4 reactor technology. Is it considered Gen 3+ because it's SMR combined with BWR?

[marcusoutdoors]

Really interesting and well delivered presentation. Thank you.

These nuclear reactors operate at way to low a temperature to actually store power as heat and to low a temperature to be useful for industrial use. These reactors also have safety issues in that water has to be held at high pressure to get any efficiency in the system. Because of this danger expensive containment structures need to be built. Still without cooling pumping working after an accident hydrogen explosions are possible which can destroy even the strongest containment structures. Makes much more sense to use liquid metal or salt that does not have the hazards of high temp hight pressure water

[乾淨核能]

love all your videos about nuclear power!!! Helps me tremedously while I try to demythify nuclear power rumors to the publics!!! Keep up the good work!

[Ehsan-Musafir]

A video on Gen 10th BWRX-300 would be interesting. some videos go into too much detail which becomes jargon for people who are not Nuclear engineers while some don't give enough detail.

[markarca]

The only drawback of BWRs is that the water and the turbine becomes radioactive because the water comes in direct contact with the uranium.

[Dakiraun]

Great simplification of the more conventional type reactors!

[alext]

Agreed. All these different technologies are just distracting people from what is important, causing further stagnation in an already frustratingly slow moving industry. I like hard statistical proof, which supports the use of BWR due to it's proven history, low-risk, simple design, and demonstrable cost effectiveness. GEH BWRX-300 is the future IMO, anything else is just noise, unless proven otherwise.

It should could be standardized, modularized, and mass produced, which would lower OCC considerably leading to widespread acceptance of nuclear energy and humanity can finally be ushered into a true golden age.

[yazanatrash]

Great job, one more advantage you forgot to mention that in BWRs the reactor vessel and associated components operates at lower pressure compared to PWRs

[ChadJBoyer]

BWR fuel assemblies are smaller than PWR. The picture you show of a PWR is not what is used in Western style PWRs (US, France, Asia). The BWR picture you had is actually 4 assemblies around a cruciform control blade.

Also, the BWRX doesn't use recirc pumps so you can't vary power as your described.

[tobyw]

Does BWR not require HD pipes and other materials in order to safely contain the high pressures and corrosion of the steam in the radioactive cooling (heat transfer) system which is transferred to the high pressure, non-radioactive part of the system? I'm reading that atmospheric pressure in non-boiling areas (molten salt or molten metal) have only to contain these low pressures by resisting corrosion, not high pressure plus corrosion.

[JMVuko]

Your presentation is fairly done considering the length.

[elizabethescobarvera]

I still domt understand the fuel part, can you explain it? What ks the differnet between a candu reactor and a SMR( bwrx300)

[mohsinalisiddiqui]

If I were a nuclear student, I wouldn't mind missing a few lectures on reactors because Osama Baig's Channel will fill me on that 😋

[vejet]

"Drying water" that sounds like such an oxymoron... I know I know, it's so that liquid water doesn't get into the steam lines. But wouldn't some of the steam condense along the way to the turbines anyways?

I used to prefer BWR's for their simplicity in the elimination of the secondary loop. But the whole, insert control rods from the bottom up concept has me a little worried. Sure there hasn't been a case where they've failed to insert, or at least I don't think there's been one... But after all these nuclear disasters I would prefer a design which is as fool proof as possible and going with gravity as opposed to going against it at least eliminates one potential future failure mode.

[perryallan]

The overall issue is that PWR's have proven to be generally more economical to build and operate than BWR's. That's why BWR's make up only a small portion of nuclear power plants in the world. Theory is great. Real world practical experience say that great theories don't always work well in the real world.

Note that Westinghouse recently announced a 300 MW "modular" PWR based on the AP1000 design (and using some of the same components and controls). I think thats going to give the the recent GE 300 MW "modualr" BWR a run for its money.

The AP1000 is the most successful modern large PWR design in the world. 6 have been built and I believe there are orders and letter of intents for at least a dozen more. Even the Chinese recently ordered more AP1000's over its home grown PWRs because they are working so well.

Never would have thought boiling water had a backstory
