India’s 1st Indigenous Nuclear Reactor is Ready | Benefits of Pressurize heavy water reactors PHWRs 

HARD WATER AND HEAVY WATER ARE DIFFERENT, HARD WATER HAVE DISSOLVED SALTS WHILE HEAVY WATER(D2O) IS WATER WITH DEUTERIUM A ISOTOPE OF HYDROGEN

Heavy water isn’t hard water. It has a neutron in its hydrogen atom, about doubling the weight of the hydrogen which normally only has a proton. I believe we have to manufacture it with electrolysis. Congratulation though. Great news

We need to get serious on commercial thorium reactors. ASAP.

Sir,We cannot use hard water which contains magnesium and calcium which solidify on inner walls of boiler ans act as thermal insulators reducing the efficiency of the power generation While heavy water means D2O contains two deuterium instead of hydrogen atoms giving it nuclear characteristics So hard water and Heavy water are not same, slide in the video shows hard water containing calcium and magnesium

As a youth aspiring for a government job, I heard the news about KAPP, a nuclear power reactor, commencing its commercial operations. Intrigued by this, I decided to delve deeper into the matter. After watching Sir Amit Sengupta's video, I gained a clear understanding of it all.

Hey! I'm not from India, but as part of a university project I was researching Uranium Enrichment, and came across some articles about a Facility located in a city called 'Mysore'. You should make a video on that! Congratulations India, please stay safe!

I didn’t see this news either in the print or electronic media. The political drama of Maharashtra is more important for them. Many thanks for bringing us this important news, giving us Gyan about the type of nuclear reactor in use for power generation.

Excellent News! Indian transition from coal to nuclear is very important both for the country itself, and for the rest of the world as part of the global effort to slow climate change.

Congratulations India.

Well done, india!

Decent research and a good explanation for Layman understanding. Please allow me to clarify few things. *India has been operating 200MW and 550MW for almost 2 decades now. It is the 700MW unit that is first of its kind. The news article says "India builts its first 700MW nuclear reactor" Nuclear Reactors are not build in 2-3 years. The planning, development and administrative process were carried out before modi government came to the power. Associating this with a particular government would indicate unnecessary political biasedness. What is being delivered now is a fruit of the efforts of the previous government. In contrast to the public opinion, R&D in India is at the same pace as it was before, if not reduced due to now overly tedious purchase process. (I am qualified to say this) * Secondly, -PWR is technology of the US, -PHWR is canadian design -BWR is of Europe's design (now slowly being phased out) -Graphite moderated reactors were Russian designare (now phased out due to their risky nature; remember Chernobyl? ) MSBR, AGR, SMR are demonstrate concepts whose safety costs outweighs the economic viability. PWR is superior to all. Basically simple and robust design. Fuel it once and forget it for 30 years. India uses PHWR type only because it can runs on natural uranium. Frequent online refuelling (usually few times an year) is required which increases radiation and proliferation risk associated with material handling. As per IAEA's standard India doesn't even have the Uranium ore. Still, India works with what it has, as best as it can. *All radio isotope generation and other things can be done in any nuclear reactors. PWRs being haveing relatively higher neutron flux are infact more efficient at that. *Heavy water and hard water are different thing. Hard water has dissolved salts that make it hard while heavy water doesn't have any salts but the atoms itself are deuterium instead Hydrogen. It is costly and cannot be extracted from aquifers. Heavy water for indian nuclear reactors is supplied by heavy water board (HWB). Moreover, the heavy water is only used as neutron moderator, not for cooling. It is the light water that runs into primary cycle that is used for cooling. PHWR reactor is not inherently safe like PWRs. We should be proud at our achievement but at the same time not overlook out limitations. Particularly in nuclear industry. It is that kind ideology that resulted in Chernobyl.

I was one of the engineers in LnT which has built the civil infrastructure of Kakrapara nuclear reactor. It feels so good to see it working.

That's great news, considering the certainly fast growing energy needs of India.

Need a video on the Indian thorium story. It's reported theft in TN and prevention on the development of thorium based reactor. India reportedly has the highest thorium deposits.

I too reached criticality via your videos.....

You meant heavy water, not hard water. Heavy water is not naturally available it uses deuterium its hydrogen isotope. Hard water will have various silicates, chlorides fluorides etc in it.

I'm a fan of CANDU-type reactors, which India's PHWR discussed here seems to be an offshoot. However, as the narrator insists on saying, heavy water (D2O) and hard water (H20 laced with dissolved minerals) are hardly synonymous with one another.

Sir, Hard water and Heavy water are two different things. Heavy water is D2O, while Hard water is H20 with salts of Chlorides, Carbonates and Sulphates.

Sir kindly cover some more India's powerplant in a separate videos..

Congratulations India, what an excellent achievement.

I just watched rocket boys and this video is perfect to follow after that

My friend is Scientific officer at kakrapara nuclear power plant of DAE.

May we see such thing in existence very soon in Nigeria .

Congrats India! :D

Your videos are always informative. Thanks ❤

Please make a video on what is difference between economics and economy

Thank you for Your Efforts Sir

Two reactors should have been installed but only one installed by dec2022 Already missed several deadlines

Sir, Heavy water and Hard water are two different things. May please review.

I think there was a bit of confusion in the beginning. Hard water is water with a good amount of dissolved salts. Heavy water, on the other hand, is water that has varying degrees of extra protons 2H (Deuterium) and 3H (Tritium - very rare).

It will be helpful to know % of imported components in such 700 MW reactor Thanks RKSundaram

Sir, you should've also added how the outcoming hot water is discharged. Untreated or warm water discharge often lowers down the pH levels of the water body thereby destroying the river biodiversity of that area.

Jai guru good evening sir excellent feeling happy guru poornima 🙏👍

@Amit Sengupta: 2:00 It is not hard water, it is heavy water. Heavy water is an isotope of normal water where deuterium bonds with oxygen instead of hydrogen. Deuterium is an isotope of hydrogen with one extra neutron. The extra neutron increases the likelihood of slowing down the speeding neutrons, and therefore, is a better moderator compared to normal water. Hard water is simply normal water mixed with several minerals / salts.

Thank you, Amiy...very cool...blessings

Thank you so much sir. ...🙏🏻😊🙏🏻

Nice to see new nuclear plants coming out. Good job India

🎉🎉🎉 superb feat! Wohoo!!

Subscribed to your channel for the content as well as your soothing voice. :)

Good video. You need to edit and Re upload the Vedic after correcting the mixup about heavy water and hard water.

Sir, please make a video on India's 3 stage nuclear program

Can you make video on progress status of thorium reactors in India.

I think hard water and heavy water is not the same thing. Please explain someone.

Last 20 yrs we are still building FBR in kalpakkam after 13 yrs research i.e. 33 yrs lost, although they went ahead with production plan after Prototype FBR has been running 8 yrs in criticality. I don't know why there is so much disparity between nuclear scientist in 2 different locations

You are coming out with a very informative video after a rather longish hiatus. Need more of your well researched video knowledge trove to stay informed.

Make a video on India's first thorium nuclear power plant being built at Kalpakkam.

Make more of them ....prefect its tech and import tech u have to.....india must excel in everything

Waiting for 900 MW reactor soon India needs to catchup many countries going on with >1000 MW reactor

Thank you sir...

Hard Water and heavy Water is different....Don't confuse it..... Heavy Water comes from heavy Water Reactor from normal water and not hard water

Thanks for the video sir 🙏

Thanks for such video

tthank you so much sir

Happy gurupurnima sir..🙏🙏

Hi @Amit Sengupta sir. Can you please explain the 3 stages of India's Nuclear Programme?

Intresting way of explanation

Thanks sir 🙏 🎉

Happy Guru purnima sir 🙏🙏🙏

& thanks for the info/video.

Good information Good explanation..🙏🙏🇮🇳🙏🙏

Thanx for information.

Thank u for such video

Please correct. PHWR uses heavy water which is water with the deuterium isotope if hydrogen. It is produced from natural sources of hydrogen through cycles if enrichment. India is presently the largest producer of heavy water. Hard water is essentially impure water which cannot be used in any industry as it is.

wow, congratulations

Happy guru purnima sir 🙏🙏🙏

Can you please create a video on AERB and VECC?

Thank you sir for sharing unpriced knowledge. 🔥👍 Jai shree Ram

Sir Surat is in which zone of earthquake. Is it any worry from it.

Gujarat ko puri tarike se self sustaining state bana diya Indian govt ne...Well done. Baaki states bhaar me jaaye.

Any updates on India's Thorium powerplant ?

Heavy water and hard water are different. Heavy water is deuterium water. Hard water is normal water with high concentration of magnesium and calcium salts .

Just like 3-4 days ago heard someone asking why India isn't building small sized nuclear power plants across country to fulfill India's energy needs.? And here I'm getting news that we have built one and about to build 4-5 s...

Amazing explanation as always!

Well researched & presented informative video, Amit. How many Nuclear reactors in operation does Bharat have presently? How much electricity are they generating?

Hello sir, I have heard our nuclear ballistic missile submarines also use indigenous nuclear reactor. Can you clarify the differences between these types?

Please make a video about what is happening in Manipur & why 🙏

Thank you God for blessing India with a fantastic govt .....🙏🙏🙏

Fantastic! Please explain manipur incident

Make a video on Rosatom they are just amezing organisation.

Thank u sir

Congratulations 😊

Sir, where r we in terms of small modular type nec fu reactors

Any news about thorium reactors?

Excellent timing specially when japan wants to release its "treated " water in the seas

Amit sir, I want to see you as our upcoming EAM in future. ❤ From West Bengal.

Dear Amit You have an amazing voice and great command on English. 👌 However, there's a correction that needs to be made in your text. Heavy water is made up of Dueterium Oxide ( D20) which is mildly radioactive. Whereas, hard water is made of dissolved salts, like calcium magnesium sulphates and chlorides!

2:25 #Hard water - Ca++ or Mg++ ions in regular tap water are bad for reactor. It leaves white residue on boiling. #Heavy water - D2O (not H2O) is good. D stands for Deuterium isotope of Hydrogen with 1 proton & 1 nutron.

Heavy water and Hard Water are 2 different things. Hard water is what you normally get in your toilets for flushing, it's usually drawn out of the ground-water tables and are not purified off disassociated radicals etc. Heavy water is water made of a heavier isotope of Hydrogen called Deuterium.

Just waiting for when India's east sectors are adopted this tips of technology

Congratulations from France !

Jai Hind. Indians BBBW and, India nuclear could now start making money by building 700 MW plants all over in UK and US where there had been a costs runaway nuclear reaction.

Happy guru Purnima Amit g 🧘‍♂️🇮🇳🙏

Informative video, thanks! Just a minor point, I don't think Hard Water is the same as Heavy Water. Hard water means water that has impurities and does not create good lather with soap. Whereas Heavy Water is Deuterium based water

Did not get the information about the locations? At first you told about 3 locations but you mentioned 5 other names in slide😢

Good 👍

Guru purnima ki hardik badhai sir🙏🙏

Good news Thanks amit bheji.

Indian technology at its best.

And you also have to mention recent terrible Rail Accidents when you admiring Indian Rail

What about fast breeder reactor??
