PARLIAMENT QUESTION: NUCLEAR POWER GENERATION
Posted On: 04 FEB 2026 5:49PM by PIB DelhiNuclear power generation in the last two years 2023-24 and 2024-25 was 47971 Million Units and 56681 Million Units respectively.
The details are as under:
* Mahi Banswara-1&2 and Mahi Banswara-3&4 being implemented by ASHVINI, a Joint Venture of NPCIL and NTPC.
Pre-project activities are in full swing at different stages in different projects. They are nearing completion in Kaiga 5&6.
Further, BHAVINI is currently commissioning a 500 MWe Prototype Fast Breeder Reactor (PFBR) project at Kalpakkam, Tamil Nadu. Government has accorded approval to carry out pre-project activities for 2 x 500 MWe twin unit of FBR 1&2 project at Kalpakkam, Tamil Nadu. On attaining first criticality of PFBR, Government will be approached for financial sanction of FBR 1 & 2 projects.
In the last two years a capacity of 2100 MW has been added by completion of KAPP 3&4 (2X700 MW) and RAPP-7 (700 MW) taking the installed capacity to 8780 MW (excluding RAPS-1), towards achieving a capacity of about 22 GW by 2032.
Constant monitoring of progress of project activities at multiple levels, timely identification of constraints & making necessary mid-course corrections, frequent meetings with vendors/ contractors and re-sequencing of construction activities to the extent possible, are being taken to ensure the timely implementation of the projects. As regards ensuring enhanced plant availability a programme of predictive and preventive maintenance of equipment and components based on the health assessment using latest technology & tools and In-Service-Inspections is in place in operating stations of NPCIL. NPCIL’s operation and maintenance practices have ensured that its reactors record long continuous operation periods. NPCIL’s reactors have so far recorded continuous operation more than a year 54 times.
Two Small Modular Reactors (SMR) viz. BSMR -200 and SMR -55 are planned to be set up at Tarapur, Maharashtra site. In addition, Tarapur Atomic Power Station’s Units 1&2 (TAPS 1&2 – 2X160 MW), which commenced operation in 1969 and are the oldest reactors in the world, are presently undergoing refurbishment to extend their life further and expected to generate electricity soon.
This information given by Union Minister of State (Independent Charge) for Science & Technology and Earth Sciences, and Minister of State in the Prime Minister’s Office, Personnel, Public Grievances and Pensions, Atomic Energy and Space, Dr. Jitendra Singh in a written reply in Lok Sabha today.
From Institute for Plasma Research Newsletter
Have they announced if they're going for IPHWR-540 or IPHWR-220 or a foreign JV?
Also, anybody know if after iphwr-700 are there plans for a newer reactor with higher power output?

yes lol, the US spends tens of billions on this research eveyr year, money that india simply does not have. We are catching up faster but we will not reach them for a significantly long time. Not even china will.
BARC develops advanced reactor for Indian Navy’s next-gen submarines
Bhabha Atomic Research Centre is developing a 200 MWe reactor for India's next-generation submarines, significantly enhancing their endurance and submergence time.
I thought the 200MWe SMR was IPHWR derivative but article says it will be a LWR.
But also the article says that S5 class subs will be powered by a 200MWe Reactors (
)200Mwe is like 600Mwt? thats like an A1B class reactor lmao. even if we have developed a reactor of that size it cant fit in a sub lol. Theyre wrong. Its a 200Mwt class reactor.2025 articleBARC develops advanced reactor for Indian Navy’s next-gen submarines

Even the official StrategicFront channel claimed the CLWR-B1 was 83MWe!
So how can CLWR-B2 be 200MWth = 65MWe.
The mods of this site are colluding to hide high levels of local IPR to avoid ToT to foreign nations!
mate the reactor used in the columbia class sub(21k tonnes) is 220-250 Mwt. Unless BARC has somehow surpasses the US in nuclear sub reactor tech its not 200Mwe lol.
a 200Mwt reactor for the 13k tonne ship is powerful. Like insane power to weight ratio lmao.
CLWR-B1 is 83 MWth while CLWR-B2 is 190 or 200 MWth.
Using a nominal 31-33% efficiency rate, that translates into 26-27 MWe for B1 and 59-66 MWe for B2 (let's round that off to ~25 MWe & ~60 MWe)

Basically, the writer made a mistake & the paper's editor didn't know any better to check feasibility.

Indian Nuclear Attack Submarine (Project 77) - Updates & Discussions
This part of @Parthu's recent article stuck with me: So, I made a chart of power to weight ratios of all IN subs (present & future): Figures marked with a Tilda (~) are my guesstimates. Don't take those numbers literally. You are right P77 should enjoy a major advantage, even if we were to...

Yeah, that was me. It should have been MWth not MWe. Sorry.
Kris Singh, chairman and CEO of the American nuclear equipment supplier company Holtec International talks about his company’s ambitious plans to manufacture small modular reactors (SMRs) at scale in India, why they are suited for India and the challenges that lie ahead.
