ஐம்பது ஆண்டு காலம் தமிழ்த் திரையுலகில் தன் அசாத்தியமான திறமையாலும், படைப்பாற்றலாலும் பல வெற்றிப் படங்களைக் கொடுத்து, தமிழ் மக்கள் மனதில் நீங்கா இடம் பிடித்தவர் நண்பர் திரு. பாக்யராஜ் அவர்கள்.

அவருடைய திடீர் மறைவு எனக்கு மிகுந்த வேதனையும், அதிர்ச்சியும் அளிக்கிறது.

அவர் குடும்பத்தினருக்கும், சார்ந்தோருக்கும் என் ஆழ்ந்த அனுதாபங்கள். ஆத்மா சாந்தியடையட்டும்.

India's Fast Breeder Reactor just achieved criticality at Kalpakkam.

Everyone's sharing the headline. Almost nobody is asking: who actually built this reactor?

I went through multiple sources to find out which listed companies have verified involvement in this exact PFBR project. Not "nuclear theme" plays. Actual Kalpakkam suppliers.

Here are the names👇

1. Kirloskar Brothers:
The PFBR runs on 1,750 tonnes of liquid sodium as coolant. Someone had to build the pumps that move all of it. That someone is KBL.

Kirloskar manufactured the Primary Sodium Pumps at their 100 year old Kirloskarvadi plant. Three pumps. 135 tons each. Handling 5.16 lakh liters of liquid sodium per minute.

Their AVP Ravindra Ulangwar said on record: "We at KBL are the only Indian company to develop such type of critical application pumps."

They also built the Secondary Sodium Pumps that sit outside the reactor vessel and cycle the sodium back after heat extraction. Without these pumps, the reactor literally cannot function.

KBL has also supplied pump sets for ITER, the international nuclear fusion project. So this isn't just domestic capability. Global validation.

2. MTAR Technologies:
MTAR built some of the most complex precision equipment inside this reactor.

-Grid Plate Assembly for the PFBR. 8 meters wide. 80 tons. 1,758 tubes with positional accuracy maintained within 0.1 mm. If even one tube is misaligned, the reactor doesn't work.

-Inclined Fuel Transfer Machine. 22 meters tall. 200 tons. This is the system that physically moves spent nuclear fuel out of the reactor building. MTAR designed, manufactured, and tested it entirely in house.

-They also supplied the Control and Safety Rod Drive Mechanism and the Central Canal Plug for the PFBR. The control plug alone is 2.5 meters wide, 12 meters tall, 56 tons.

And here's the moat: MTAR is the sole qualified domestic supplier of Fuel Transfer Systems for NPCIL's reactors. Vendor qualification takes 5 to 7 years. You cannot buy your way into this position.

What's coming next: ~₹800 Cr order pipeline from Kaiga Units 5&6. ₹300 to 400 Cr expected from 5 refurbishment reactors. And 10 fleet mode reactors haven't even been tendered yet.

3. Walchandnagar Industries:
The smallest company on this list. And arguably the most directly exposed.

WIL executed the entire sodium piping contract for this 500 MWe PFBR at Kalpakkam. Supply, erection, and commissioning of mechanical, piping, and instrumentation for the sodium and miscellaneous systems.

Think about what that means. Sodium piping in a fast breeder reactor isn't regular plumbing. Liquid sodium ignites on contact with air and explodes on contact with water. The precision and safety requirements are extraordinary.

WIL has been working with the Department of Atomic Energy for over four decades. They're pre qualified by NPCIL, BARC, and BHAVINI for Class I nuclear components, the highest classification that exists.

They've also supplied Calandrias, End Shields, Dump Tanks, Fuel Magazines, and Moderator Heat Exchangers for India's 220 MWe and 500 MWe reactors.

4. BHEL:
The large cap in the room. BHEL supplied the turbine island for the PFBR. In fact, BHEL has been the turbine island supplier for every Indian nuclear plant including Kudankulam and Kakrapar. The PFBR is no exception.

The motor that drives Kirloskar's Primary Sodium Pump? That's a BHEL motor.

Not a hidden gem, but it would be dishonest to talk about who built Kalpakkam without mentioning them.

5. L&T:
Built the reactor vessel and core structural systems for the PFBR. India's only private sector player with nuclear grade heavy engineering capability at this scale. Again, not hidden, but directly involved in this reactor.

So why does all of this matter now?

Because Kalpakkam isn't the end. It's the beginning.

Six more 600 MWe Fast Breeder Reactors are already planned. India's nuclear capacity is going from 8,180 MW today to a target of 100 GW by 2047. The SHANTI Act 2025 just opened nuclear to private sector participation for the first time in India's history.

Every single future reactor will need sodium pumps, fuel handling systems, sodium piping, turbine islands, and reactor vessels from qualified suppliers.

And nuclear qualification takes 5 to 7 years. The companies already inside this ecosystem today have a head start that no amount of capital can shortcut.

Sir, we’ve all grown up measuring “entertainment” with just one benchmark, YOU. ❤️
Making us whistle, laugh, cry and feel larger than life for decades and still doing it with the same swag and grace, that’s pure magic.
So for you to call Dhurandhar 2 a “must watch” feels like the biggest ‘superstar’ moment of my life.
It feels like a blessing from the very person who taught us all to dream bigger.
Grateful beyond words, Sir.
This one is going straight to the heart.
Jai Hind 🇮🇳 🙏
