My papa(grandpa) worked at and helped build darlington
I have inspected nuclear
Reactor components for the last 56 years and
Are still at it in 2022.
Very well explained by the official. Safety security systems are highly commendable. Thank you Canadian Nuclear Safety Commission and Government of Canada. Vinaka vaka levu from Fiji Islands.
An oddity about this video : when the assembly of a fuel bundle is illustrated, a 28-element bundle is shown. This type is used only in the CANDU units at Pickering. The four Darlington units, along with the eight at Bruce, as well as Point Lepreau in New Brunswick, Embalse in Argentina, Cernavoda in Romania, and others, all use 37-element bundles with three concentric rings of pins (6, 12, 18) around a single central pin. KANUPP in Pakistan, and the CANDU-derived Indian PHWRs use 19-element bundle (minus the ring of 18) of similar construction.
Nice one!! .. good catch!
On behalf of Cernavoda NPP , I confirm.
KANUPP and NPD used 4" pressure tubes thus the smaller bundles
Build more
In 5.23 we see a wall of tools. What brands do you use? Stainlless combination wrenches?
Awesome video, always wondered what it's like in there, thanks OPG!! (y)
You can shut down a reactor in 2 seconds!? That's impressive. I read a little bit about the CANDU reactors and I think they are very safe and "clean" for a nuclear power plant. Specially they can take the spent uranium of a LWR plant and use it.
As far as I know we don't and never will. The throw-away cycle is much cheaper and less politically sensitive than recycling spent fuel. India is interested in thorium breeding so it can use its thorium sources but that's because they like to be self-sufficient, not because its easier or cheaper.
Not clean. Underground pipes, it's a mess.

Jus bc u shut down a reactor doesn't mean it's shut down...there's a huge problem called decay heat that has to be dissipated for months before its truly shut down
@@hondamoto-rb6bk It takes another normal generator to supply electricity to the mess for years after it's shut down...how can this be a cost effective method? It's an insane way to boil water!
Thank you for Generating power for us in Oshawa, though itd be nice if Oshawa could keep its power grid in shape, random places get power outages that cause problems like no power at home or no power at work. Darlington is something I pride my self on being a neighbour to it, a proper clean Canadian nuclear power plant.
Chernobyl and Osaka residents were "proud" once upon a time too. At least when the power wasn't inexplicably "out" for "neighbors" of those "clean" nuclear powerplants. Or maybe they weren''t dumbasses like you and "proud" of something they had nothing to do with besides being a "neighbor" of it and a "consumer" of it's "product" 24-7-365 except for "occasional" outages. Of course being Canadian I"m sure the "outages" at "work" don't bother you since that's probably a "paid holiday" and if the "outages" are THAT "spotty" that they can be at "home" OR "work" which must be the case if you didn't just say "outages" without specifying two different "types" or "sectors" or "examples", you probably don't mind an "outage" at HOME either if it means you're just not able to get "ready for work" or "get to work" because you just can't function without electricity and neither can your garage door opener. So...PAID PERSONAL DAY!
Of course the real question is are there really "isolated" outages ONLY at "work" and not at "home" and vice versa? Or are you assuming that there are because when an "outage" occurs at "work" you and your "co-workers" immediately run to your vehicles - because you obviously can't "work" in the "dark" or without "power" for whatever electrical/electronic "devices" you operate as your "job" that really do the "work" for you or in spite of you but definitely not because of you - and upon arriving at "home" (eventually) you find no "outage"?
Or maybe you make that assumption because when you have an "outage" at "home" and just can't get to work and perhaps all of your "co-workers" can't either and it's just an automatic "day off" when "homes" are without power and later on your "day off" when you manage to get "out of the house" and "have" to go downtown or into town or across town or wherever "home" isn't and "work" is there's no "outage" THERE?
About gotta be one or the other since "outages" that "spotty" or "isolated" don't result from sudden "issues" at the POWERPLANT where "outages" are ALWAYS PLANNED AND LAST FOR DAYS, WEEKS, MONTHS OR YEARS AND YOU NEVER HAVE A CLUE THEY OCCUR BECAUSE THEY DON'T AFFECT YOU THE "NEIGHBOR" OF THE POWERPLANT BECAUSE YOUR "POWER" DOESN'T GO DIRECTLY FROM THE "GENERATOR" TO YOUR "HOME" AND "WORK" PERIOD MUCH LESS ON TWO SEPARATE LINES OR "GRIDS" AND/OR "GENERATORS".
YOU ARE A "CUSTOMER" OF THE LOCAL UTILITY POWER "PROVIDER" WHICH CONNECTS YOUR "HOME" TO THE "GRID" AND SUDDEN AND/OR SURPRISE AND/OR SHORT-TERM "OUTAGES" - WHICH RARELY LAST MORE THAN SECONDS TO MINUTES UNLESS THEY TOO ARE "PLANNED" IN WHICH CASE SAID "PLAN" WAS/IS MADE "PUBLIC" BEFOREHAND AND LAST A FEW HOURS AT MOST AND WHICH NEVER OCCUR BEFORE OR AFTER "OFFICE HOURS", OR ARE "EMERGENCY" OUTAGES DUE TO WEATHER, SOMEBODY HITTING A POWER LINE OR POLE WITH A VEHICLE OR CONSTRUCTION EQUIPMENT, SOME SORT OF TECHNICAL OR MECHANICAL "ISSUE" THAT CAUSES TRANSFORMING AND OR TRANSMISSION "ISSUES" SOMEWHERE "UPSTREAM" OF "HOME" AND "WORK" WHETHER "LOCAL" OR "REGIONAL".
AND UNLESS "HOME" AND "WORK" HAPPEN TO BE ON DIFFERENT "LOCAL" UTILITIES/GRIDS THAT HAPPEN TO HAVE DIFFERENT "SUPPLIERS", EVEN BEING ON DIFFERENT "UTILITIES" ISN'T GOING TO RESULT IN AN "OUTAGE" AT "HOME" BUT NOT "WORK" OR VICE VERSA ABSENT A MUCH MORE "LOCAL" AND "EMERGENCY" AND "SHORT-TERM" OUTAGE LIKE A BLOWN TRANSFORMER OR DOWNED LINE OR POLE "NEARBY" AND THAT'S NOT EVEN CONSIDERED AN "OUTAGE". ITS AN "INTERRUPTION". TO A "SERVICE". AND IF YOU CALL AND REPORT IT LIKE YOU SHOULD AS SOON AS YOU'RE AWARE OF IT YOU'LL PROBABLY FIND OUT IF ITS AN "OUTAGE" OR "INTERRUPTION" AND HOW "WIDESPREAD" IT IS.
THE ONLY WAY YOU CAN HAVE "OUTAGES" AT "HOME" OR "WORK" BUT NOT BOTH OFTEN ENOUGH TO CAUSE SUCH A "PROUD NEIGHBOR" OF A NUCLEAR POWERPLANT TO MAKE "OH BY THE WAY" MENTION OF IN A PUFF PIECE PRO-POWERPLANT PROPAGANDA POST LIKE THAT FROM SOMEONE ELECTRICALLY IGNORANT ENOUGH TO THINK THEIR "HOME" AND "WORK' CONNECT DIRECTLY TO ANY "POWERPLANT" HAS NEITHER PROVIDER, DISTRIBUTION, TRANSMISSION OR GENERATION IN COMMON AT "HOME" AND "WORK" AND WOULD HAVE TO BE "PLAYING HOOKY" FROM "WORK" AND BLAMING "POWER OUTAGES" AT "HOME" FOR NOT BEING AT OR HAVING TO LEAVE "WORK" SUDDENLY AND/OR IS "PLAYING HOOKY" FROM "HOME" AND IS BLAMING HAVING TO STAY LATE AT OR GO IN EARLY TO OR GO "AFTER HOURS" TO "WORK" ON AN "OUTAGE" AT "WORK" WHEN THERE IS NONE AT "HOME".
OR THEY'RE PAID SHILLS POSTING PRO-POWERPLANT PROPAGANDA ONLINE AND ACTUALLY ARE OR ARE PLAYING "DUMB" WITH THE HOME/WORK "OUTAGE" BULLSHIT AND ALSO WITH THE "NEIGHBOR" COMMENT. AND THE "CLEAN" COMMENT.
SO WHAT ARE YOU? LAZY, STUPID, A SHILL, A LIAR, A FOOL, CHEATING ON YOUR SPOUSE, A SPAMMER FOR "BIG POWER", PRO-DIRTY, DANGEROUS NUKE "INVESTOR"?
OR THE MOST UNLUCKY, UNLIKELY, UNASSUMING, UNEDUCATED AND UNINFORMED "CONSUMER" OF ELECTRICITY TO EVER BE SUDDENLY INSPIRED TO LEARN ABOUT HE NUCLEAR POWERPLANT "NEXT DOOR" VIA RUclips VIDEO AND I SAY "HI!" AND INTRODUCE HIMSELF/HERSELF TO AND TALK TO "IT" IN THE COMMENT SECTION LIKE "IT" IS LISTENING TO ITS "NEIGHBORS"?
@@deeremeyer1749 Thing is buddy, our Nuclear Power plants are designed differently than the typical vertical reactors of most other plants. CANDU nuclear reactors are virtually immpossible to melt down due to their design. If they over heat, the fuel channels will sag and contact the reactor shielding and bleed heat off and we dont use highly enriched uranium.
So far the worst thats happened with any CANDU plants are leaks of heavy water like at the old Pickering A & B plant.
Also the outages here aren't from the power plant, theyre due to a crappy grid that has now become much better today than I commented 3 years ago. The only time our power goes our now are a result of maintence on our building or faults that cause switching stations in areas to trip and knock out power to an area.
I realy dont think that a Chernobl or Fukushima will ever happen in ONtario due to the design of a CANDU. If it does, theres a lot more Canada I can move to (besides, I kinda want to live in Alberta or Saskatchewan or perhaps other hot dry places in North America)
@@deeremeyer1749 All he said is that he's happy that the power grid is getting better and he's proud to be apart of a community that's actually helping the environment.
YIMBY - Yes In My Backyard.
This is unusual in the world, but common among nuclear power plants once they are up and running.

great video
Nuclear power is one of the greatest sources of energy ever. Antinuclear hysteria is one of the most retarded sentiments in history.
My dad worked for AECL for about 25 years, starting in 1965 at Chalk River after working on the design of the Iroquois engine and then the Gemini and Apollo escape mechanisms. In 1967 we moved to Bramalea where he started working at Sheridan Park as a reactor instrumentation designer.
By looking at the dates does anyone have any idea which reactors he might have helped design?
He said that one of the hardest projects he worked on was in figuring out a way to insert an instrument into operating reactor. From start to finish it took 3 years.
Ya probably Pickering A or could have been Bruce A they where both being built and you have to design a control room before you build it Sheridan research very cool!smart man!
Apparently the Canadarm in space is based on some of the principles that were learned during the insertion and removal of things into live CANDU reactors.
@@TheGeeoff My brother (his son) worked for the contractor to McDonald Dettwiler that built the wrist of the Canada Arm. He personally developed the stereoscopic video system used for docking at the space station.
Why does it say at the beginning that it is one of Ontario's 2 nuclear power generating stations, when there are actually 3: Darlington, Bruce and Pickering?
I had the same thought, then realized they said OPG's 2 stations, not Ontario. So not including Bruce.
I really like this video
can you make more of theese reaktors and place them all over the contry if you can
I really like this video. It's nicely illustrated, understandable, informative, takes you through it a step at a time, and has a good voice actress.
Can someone with nuclear experience in France work in a Canadian Nuclear plant?
Yes but tech is different
Who is mildly infuriated that unit four isn't blue :)
I like how they explicitly mention the “vacuum building” and that it’s a special feature of CANDU reactors, but can’t be bothered to tell us what it’s purpose is.
The vacuum building is used to take in the steam from an individual unit if it has had a loss of coolant accident. The reactor buildings are not capable of with standing the high pressures from the steam, so the steam/pressure is allowed to be directed into the vacuum building where is doused in water to condense it back into water and drop the pressure
@@mikestiglic1880 One thing you missed. If, and when, the vacuum building is used , in an emergency, the other three reactors, also connected to the vacuum building, MUST be shut down and cannot operate without the vacuum building's availability.
@@tbarry4990 Thats correct. Cant be operating the other units when there is no NPC available
@@tbarry4990 question, what if multiple (or even all) units needed to use the vacuum building at the same time? would it have that capacity?
@@Cat_578 - I would like to think that the Nuke Operators (who have trained for no less than 7-8 years) have practiced many scenarios to ensure safe shutdown. The likelihood of multiple reactor failures with the CANDU design I wouldn't even think about it it would be so low. If you're talking about a nuke bomb being dropped directly on it? ... well you're screwed anyway right?
Once one unit uses the vacuum building the operators would immediately disconnect the other units from the grid and shut them down. Information on the CANDU reactor is available on the web.
Only problem is there isn't that much uranium to go around anymore
I wonder if they will build a thorium plant in darlington
That is completely and totally wrong.
The likelihood of building any more nuclear reactors in Ontario is nil or zero. The taxpayers in Ontario will not want to foot the bill for construction of another nuke plant. The cost isn't worth it at this time. Furthermore the cost of obtaining thorium from a foreign country (Canada doesn't have enough) and relying on it for fuel would be questionable.
All CANDU reactors are capable of using Thorium fuel with minor adjustments. Thorium test bundles have been used successfully. Thorium is more expensive at this time
That was pneumatic system not an electronic...btw.
A lot of high tech shit going on here but is it really a good idea to build (multiple) nuclear power plants on the shores of the “Great Lakes”? No hate for nuke power just questioning if its a good idea with all the redundant protocols in place you would think keep away from the Great Lakes (just in case)
yes, it is. All CANDU stations are on Great Lakes (Darlington and Pickering on Ontario, Bruce on Huron). This is because the Great Lakes are excellent heat sinks. The water to cool and condense the steam back to water is drawn from and returned to the lakes. If the stations were away from the water they would require huge cooling towers, like those you see in US nuclear plants. Cooling towers are less efficient and require far more room than just drawing water from the lakes.
Interestingly, the slightly warmer water discharge from the plant (no, it is not increased in radioactivity) attracts fish, making for great fishing near the plant. All power plants need a good heatsink to work correctly, and nuclear is no exception. The great lakes provide that, and Ontario gets excellent clean power production.
@@LFTRnow I had a teacher in high school who loved fishing by Pickering Station's outflow for exactly this reason. The fish hang out right at the interface between the warm outflow water and the regular lake water.
There are also four reactors on lake ontario in the USA.
This is earth shattering on mushrooms.
At 2.09 she says, "the heavy water slows down tiny particles called neutrons, so they are more likely to hit and split the uranium atoms". I don't understand this. Wouldn't a neutron be more likely to split something it hit if it was going as fast as possible?
It has to do with Nuclear Physics. In the type of nuclear reaction described here, neutron has to be slowed down to "thermal energy", where it will most likely to cause fission. If this is not done, neutron is more likely to fly through an atom at high speed and won't even notice it.
Ah! Now I see...so simple, really! Thanks.
"fast fission" is possible but not as likely as "thermal" or slow fission.
Fast fission generates more neutrons(like 5-6, while slow fission generates 2-3) and can fission certain elements that "slow" fission can't. This can be taken advantage with specific reactor designs that take like 20-30% enriched uranium-235 (or plutonium-239), put those in the middle of the reactor and surround it with fuel rods containing mostly transuranic elements and Uranium-238 (can derive from spent nuclear fuel). The neutrons generated in the middle are used to fission the elements in the surrounding rods. These reactors also produce Pu-239 from the U-238 and either fission it all or let it accumulate so it can be extracted through reprocessing and used for water reactors or, unfortunately, bombs.
Thanks
A neutron doesn't hit or split anything like a bullet, it gets absorbed into and joins the nucleus of an atom along with all the other protons and neutrons usually making that nucleus unstable causing it to split on it's own. The neutron by itself didn't smash apart the atom, the instability of the now bigger nucleus breaks apart the atom. Slowing down the neutron makes it more likely to be absorbed into that atoms nucleus rather then flying by at high speed.
Lol opg got copyright claimed
Didn't say much about vacuum column
Agreed, they didn't explain how the vacuum building is part of the saftey systems.
I worked at this place back in 1989 and 1990 while it was been built as a electrician Unit 2 was put online while I was there I worked there day shift and then the afternoon shift too better pay great wages while working there
it was built as an electrician?
It's plausible you could have met my father. He was an instrumentation designer for AECL.
Ya, and every cable was ran 3 times.
cool
I admire Canadian expertise in nuclear industry, but this story felt a bit like propaganda.

Keep the left overs in your backyard
If I had to choose between keeping the leftovers from nuclear or Coal in my back yard I would choose nuclear any day of the week and twice on Sunday.
For every TWh (TerraWattHour) of energy produced this many people die from pollution or accidents related to this type of production:
32.720 - Brown Coal
24.620 - Coal
18.430 - Oil
04.630 - Biomass
02.820 - Gas
00.074 - Nuclear
00.035 - Wind
00.024 - Hydro
00.019 - Solar
Put another way for every 1 death attributed to nuclear there are more than 112 deaths attributed to other forms of power production. My guess is those numbers for other forms of power are low because they aren't always attributed to the power production or waste stream.
Of course Solar is not feasible everywhere and is no good for base load power and can take up a lot of land that could be used for farming. Hydro isn't feasible everywhere and has other huge environmental impacts. Wind, again, is not feasible everywhere...
It is sort of like travel, Everyone accepts deaths by car, but screams about deaths by plane even though travel by plane is far safer than travel by car.
I agree with Bill Mack, I'd much rather have the waste from a nuclear power station in casks near me than the waste from a coal station, or for that matter piles nearly unrecyclable left over junk from wind turbines, solar cells or lithium battery packs.
5:27 is totally fake.... the crib actually had what he wanted and they were both smiling.
A bit wasteful isn't it? Not in terms of nuclear waste but in terms of how it is stored and how they're kept. Also the fuel bundles by itself are very wasteful too. But If they're refuelled every 4-5 years then it's a different story.
There are crews i believe that go in for refueling
CANDU reactors are able to be refueled while on-line. Generally, 12 bundles per day are loaded in the reactor.
Then What do you
Do with your nuclear waste??? !!!!!!!!
Sensibly just chuck it back into the mines from whence it was sourced. Power reactors create very very little waste. Coal fired power stations create far more waste. Coal itself is far more radioactive than low enriched uranium.
Depends on the waste. Used fuel is stored in pools of water for up to 10 years to cool before being placed in dry storage containers and stored on site. The federal Nuclear Waste Management Organization (NWMO) is in the process of developing a Deep Geologic Repository (DGR) for permanent disposal of the waste. Low and intermediate level waste (L&ILW) are sent to the Western Waste Management Facility (WWMF) for volume reduction (where possible) and storage in near surface storage structures. OPG is in the process of developing an L&ILW DGR for its permanent disposal.
@@paulanderson79 Hahaha I can assure you that's is incredibly incorrect. Low enriched fuel is bombarded with neutrons in the reactor that turns it from uranium to a multitude of extremely radioactive isotopes that last for thousands of years. It is more radioactive when it is used up.
@@milolouis I know. The concern I have is the fear that people have of 'radiation'.
@@milolouis everything radioactive to one or another level.
If you could "shut down" a reactor in two seconds... We'd be at 80-90% nuclear power in USA
"if an operator is not following the rules, we take immediate action to rectify the situation".
By changing the rules. Or by changing the name of the "operator". Or by changing inspectors.
And since "we" aren't about to tell "you" who "we" are and "we" will be on the first available flight out of "our" country when "your" reactors melt down and "we" ain't ever coming back once "we" get to our offshore bank accounts and "vacation homes" in a non-extridition "neutral" tropical island country "we" ain't about to name here, "we" wish you the best of luck cleaning up "your" mess and taking care of "your" future generations of "your" FLKs born in "your" country post-meltdown.
What is an "FLK", "you" might ask? "We" are sorry "we" forgot to cover that in "your" educational videos "we" graciously spent "our" money making for "you" and "we" will now take this opportunity to complete "your" education at no cost to "us".
"FLK" is the abbreviation for a colloquial term "scientists" and "technicians" and "engineers" and "operators" and "manufacturers" use to refer to the anonymous potential future offspring of those of "you" who are unfortunate and uneducated and unimportant and unnecessary and unworthy enough of safe, reliable and "unaffordable" and "unsustainable" light-water nuclear power "we" refuse(d) to waste "our" money on and also refuse(d) to lose "our" profits from selling the "nuclear waste" from these CANDU reactors behind "your" backs and stuck "you" with for being stupid enough to trust "us" to give a dogshit about "you" much less "future generations" outside of "our" family's and friends' "family trees". Which of course are growing far far away and/or upwind from "your" reactors .
So here's a little insider info and a colloquial term for "your" future generations because "we" have no souls and "you" can't do shit to "us" now anyway. And because "dark humor" is only "dark" to those on the receiving end.
An "FLK" is a FUNNY LOOKING KID!
GET IT?
ticking time bomb
No. CANDU reactors do not work that way. Please educate yourself.
Michael500ca just look at Fukushima it’s not as radioactive but some parts are more
Puffy you are an idiot and clearly uneducated about these things. Please stop before you embarrass yourself further.
If you understand how Nuclear energy works nothing to be afraid of. the process of nuclear power is beautiful.
@@goodra999 Fukushima was an older boiling water reactor design no longer being built. The CANDU reactors work on an entirely different principal. A loss of the heavy water coolant shuts down the fission reaction as it's the heavy water that moderates the reaction. No heavy water no fission.
What's remarkable about your remark is you edited it and is still gibberish.....
