The Finance Minister, Nirmala Sitaraman, famous in her speech that “nuclear power is predicted to kind a really vital a part of the power combine for Viksit Bharat.” She added that in direction of that pursuit, “our authorities will associate with the non-public sector for organising Bharat Small Reactors, analysis & growth of Bharat Small Modular Reactor, and analysis & growth of newer applied sciences for nuclear power.”
SMRs, that are small sized reactors of about 100 MW to 250 MW capability, are the in-thing within the power sector right now, with many international locations constructing such reactors.
Requested for a response to the assertion, M Okay Narayanan, former Nationwide Safety Advisor to Authorities of India and former Governor of West Bengal, advised businessline that he had “at all times been a votary of SMRs.”
Narayanan, who was deeply concerned within the Indo-US Nuclear Settlement of 2005, stated that organising giant nuclear reactors had change into troublesome as a result of a wide range of causes.
Describing SMRs as a “compelling answer”, Narayanan stated that whereas giant nuclear energy vegetation produce numerous nuclear waste, disposing of waste from SMRs wouldn’t be a giant downside—particularly if rising fuels, such because the ANEEL gasoline, are used.
Famend nuclear scientist and former Chairman of the Atomic Vitality Fee, Dr Anil Kakodkar, additionally welcomes SMRs. “Indian reactors are on par with the most effective on the planet,” Kakodkar had advised businessline in Might.
Former CEO of the IT large, Cognizant Expertise Options, Lakshmi Narayanan, additionally advised businessline that he was “excited” about SMRs—an space during which India is usually a international expertise chief.
Prof Ashok Jhunjhunwala, the founding father of IIT Madras Analysis Park, who taught electrical engineering at IIT Madras, is one other supporter of SMRs. Jhunjhunwala has fashioned a bunch to look at micro nuclear reactors, of capacities as small as 5 MW. The Vitality Consortium of IIT Madras is engaged on growing one such reactor.

Costly reactors
SMRs have their very own share of detractors. A latest report of the think-tank, Institute for Vitality Economics and Monetary Evaluation (IEEFA), decried SMRs as “too costly, too sluggish to construct and too dangerous to play a major position in transitioning away from fossil fuels.”
Noting that the business is “tormented by value overruns”, the report noticed {that a} key argument of SMR proponents was that the brand new reactors could be economically aggressive. “However the on-the-ground expertise with the preliminary SMRs which were constructed or which are at the moment underneath development reveals that this merely will not be true,” stated David Schlissel, IEEFA director of useful resource planning evaluation and co-author of the report.
“From 2016 to 2020, they stated the goal energy worth was $55/megawatt-hour (MWh). Now, after getting ready a brand new and rather more detailed value estimate, the goal worth for the facility from the proposed SMR has soared to $89/MWh, that too with subsidies,” the IEEFA report stated.
Nevertheless, Indian consultants are usually not impressed by the argument. Noting that inexperienced power transition couldn’t be executed with out nuclear power, M Okay Narayanan stated that even when SMRs had been expensive, “if it needs to be executed, it needs to be executed.”
Kakodkar, going a step additional, believes that India-made reactors would value “no less than half of the reactors made in Western international locations.” He additionally noticed that integration of huge quantities of intermittent technology from renewable power sources like wind and photo voltaic could be costlier than nuclear energy from indigenously constructed reactors.
ANEEL – gasoline of the long run
Curiously, all of the three – M Okay Narayanan, Kakodkar and Lakshmi Narayanan – help a couple of nuclear gasoline developed by an American firm, Clear Core Thorium Vitality arrange by an Indian businessman, Mehul Shah. Lakshmi Narayanan has additionally invested within the firm.
As businessline reported on January 10, 2024, the Chicago-based firm has developed (and patented) a gasoline, which is a mixture of Thorium and Uranium of a sure degree of enrichment, referred to as HALEU (Excessive Assay Low Enriched Uranium).
Clear Core calls this concoction ANEEL (Superior Nuclear Vitality for Enriched Life). ANEEL, which is a mix of 80 per cent thorium and the remaining Uranium enriched to a shade underneath 20 per cent, can allow India begin utilizing Thorium, abundantly accessible within the nation, for producing nuclear power. The gasoline is at the moment present process checks on the Idaho Nationwide Laboratory, USA.
The advantage of ANEEL gasoline is that it may be utilized in pressurized heavy water reactors (PHWRs), one thing that India is an skilled in. India has many years of expertise in operating small PHWRs, of 220 MW capability, at Kalpakkam close to Chennai.
The Bharat Small Modular Reactor, talked about within the finances speech, could also be an offshoot of the 220 MW PHWRs.) ANEEL can fast-track India’s entry into SMRs. “For my part, the one really working SMR on the planet is India’s indigenous “Bharat Small Reactor”,” Shah advised businessline.

“Now that India wants to attain a transition to large-scale inexperienced nuclear power deployment, the administration of a giant quantity of spent gasoline arising from imported pure uranium may change into a critical one. ANEEL gasoline can shrink the spent gasoline stock by an element of seven whereas additional enhancing security, accident tolerance, economics, and proliferation resistance,” he stated.
