EDF espère un accord "dans les prochains mois" pour six EPR en Inde

PARIS Reuters 05 Mai 2022

EDF espère parvenir à un accord "dans les prochains mois" pour la construction de six réacteurs EPR en Inde, a-t-on appris jeudi auprès d'un porte-parole du groupe.

Cette confirmation d'une progression des discussions initialement rapportée par BFMTV intervient au lendemain d'une visite en France du Premier ministre indien Narendra Modi, qui a été reçu mercredi à l'Elysée.

L'énergéticien français a remis en avril 2021 à l'exploitant nucléaire indien NPCIL une offre technico-commerciale engageante française en vue de la construction de six réacteurs EPR sur le site de Jaitapur, dans l'ouest de l'Inde.

la centrale nucléaire de Kakrapar de 2 réacteur de 700 MWe chacun fonctionne à pleine puissance. C'est un réacteur de conception et fabrication domestique.
India’s Kakrapar Nuclear Power Plant starts operations at full capacity

By NS Energy Staff Writer 01 Sep 2023

The Kakrapar Atomic Power Project is located in Gujarat, and features two Pressurised Heavy Water Reactors (PHWRs) with a capacity of 700MW each (Unit-3 and Unit-4), are the country’s first pair of indigenously designed PHWRs

India’s largest indigenously developed 700MWe nuclear power plant, the Kakrapar Atomic Power Project (KAPP) Unit-3 in the state of Gujarat, has started operations at full capacity.

Prime Minister Narendra Modi, on social media platform X, congratulated the scientists and engineers associated with the project, on achieving a new milestone.

Modi posted on X: “India achieves another milestone. The first largest indigenous 700MWe Kakrapar Nuclear Power Plant Unit-3 in Gujarat starts operations at full capacity. Congratulations to our scientists and engineers.”

KAPP is located in Kakarapar near Vyara, Gujarat, and features two Pressurised Heavy Water Reactors (PHWRs) with a capacity of 700MW each (Unit-3 and Unit-4).

The project also has two units of 220MW PHWRs already in operation.

KAPP 3 and 4 are the country’s first pair of indigenously designed PHWRs with a 700MW unit size and enhanced safety features.

According to the Nuclear Power Corporation of India (NPCIL), KAPP 3 already started commercial operations on 30 June 2023, but was operating only at 90% of its capacity.

All the civil works at Unit-4 are completed, with progressive completion, testing and commissioning of various equipment or systems in progress.

The unit has completed the hydro test of primary heat transport (PHT) system, reactor building proof test, integrated leak rate test (ILRT) and hot conditioning.

In addition, the reactor unit successfully achieved Turbine-Generator operation on Barring Gear in July this year.

India’s Union Home Minister Amit Shah posted on X: “India’s power acquires a new dimension today as our largest indigenous 700MWe Kakrapar Nuclear Power Plant Unit-3 in Gujarat starts operations at full capacity.

“It is a firm step towards attaining PM @narendramodi Ji’s vision of self-sufficiency in power production. My heartfelt congratulations to the scientists and engineers involved in the project.”

The NPCIL plans to build 16,700MW of PHWRs across the country and has granted financial and administrative sanctions for them, reported news agency Wion.

The construction of 700MW nuclear power plants is already underway at Rawatbhata in Rajasthan (RAPS 7 and 8) and at Gorakhpur in Haryana (GHAVP 1 and 2), said the publication.

Un réacteur nucléaire chaque année : l’objectif ambitieux de l’Inde pour décarboner son électricité
L’Inde a annoncé vouloir multiplier par 3 sa capacité de production d’électricité nucléaire d’ici 2032. Pour cela, le pays compte mettre en service, d’ici là, un réacteur nucléaire chaque année.

Nathalie MAYER 2 Fév 2024

En 2017, l’Inde a décidé de lancer la construction de 10 réacteurs nucléaires de 700 mégawatts (MW). Seulement 4 ans plus tard, début 2021, le premier réacteur à eau lourde sous pression (PHWR) de fabrication locale était connecté au réseau électrique du pays à la centrale de Kakrapar. Quelques péripéties et 18 mois plus tard, il commençait à produire de l’électricité commerciale. Et il y a quelques semaines, un autre réacteur a atteint son niveau critique. Une unité supplémentaire doit être mise en service en 2024. Autant de preuves que l’Inde compte bien sur l’énergie nucléaire pour faire baisser ses émissions de dioxyde de carbone (CO2) tout en continuant de répondre à la demande en électricité toujours croissante dans le pays.

Tripler la capacité de production nucléaire de l’Inde

Le gouvernement indien l’a d’ailleurs annoncé au cœur de l’été dernier. L’objectif est de faire monter la capacité de production nucléaire du pays de 7 480 MW actuellement à 22 480 MW d’ici 2031. L’idée est même d’atteindre les 50 000 MW installés en 2040. Pour y arriver, la Nuclear Power Corporation of India Limited (NPCIL) projette de mettre en service un réacteur nucléaire par an. Pour la plupart, des PHWR de 700 mégawatts électriques (MWe) comme le pays sait désormais en produire. Pas moins de 9 réacteurs de ce type sont en cours de construction dans le pays. Et au total, 19 unités sont à différents stades de mise en œuvre.

Et la Nuclear Power Corporation of India Limited assure que selon les besoins, elle pourrait être en mesure d’ajouter à ce nombre des réacteurs de 220 MWe « d’une technologie éprouvée ». Des petits réacteurs nucléaires modulaires (SMR) pourraient aussi venir compléter le tableau « sur la base de l’expérience locale dans la construction de réacteurs de puissance ».

Des réacteurs nucléaires conçus par l’Inde et la Russie

Mais l’Inde compte également sur quelques partenariats avec l’étranger pour implanter dans son pays des réacteurs nucléaires un peu plus puissants que ceux conçus localement. À l’occasion de la dernière World Nuclear Exhibition, l’Inde a signé un accord de coopération industrielle avec la France. Peut-être le signe d’une prochaine décision concernant le projet de construction de six EPR discuté entre les deux pays depuis 15 ans.

Il y a quelques jours, l’Inde a annoncé un nouvel accord avec la Russie pour la construction de deux réacteurs supplémentaires pour la centrale de Kudankulam. Alors que 4 unités de 1 000 MW y sont encore en cours de construction, 2 unités supplémentaires sont ainsi déjà annoncées. La centrale doit être achevée d’ici 2027.

India to seek nuclear investors as Kakrapar units inaugurated

23 February 2024

Prime Minister Narendra Modi's formal dedication to the nation of Kakrapar units 3 and 4 - the first Indian-designed 700 MWe pressurised heavy water reactors - took place days after reports that the Indian government is in talks with several private firms to invest in the country's nuclear sector.

Kakrapar 3 and 4 are the first of a fleet of planned 700 MWe pressurised heavy water reactors (PHWRs): unit 3 achieved first criticality in July 2020, and the unit was connected to the grid in January 2021 and was declared to be in commercial operation in July 2023. Unit 4 reached first criticality in December and is now undergoing power ascension testing.

According to the Prime Minister's Office, the two units were built at a cost of "more than INR22,500 crore" (about USD2.7 billion - 1 crore is 10 million). "They are first-of-its-kind reactors and with advanced safety features comparable with the best in the world. Together, these two reactors will produce about 10.4 billion units of clean electricity per year and benefit consumers of multiple states like Gujarat, Maharashtra, MP, Chhattisgarh, Goa and UT of Dadra and Nagar Haveli and Daman and Diu," the PMO said in a press release ahead of the ceremony.

According to the Times of India, Modi inaugurated the two new reactors and "interacted with senior officials" including Nuclear Power Corporation of India Ltd (NPCIL) Chairman Bhuwan Chandra Pathak, as well as visiting the visited the main control room of the plant.

"Went to the Kakrapar Atomic Power Station. Two new Pressurised Heavy Water Reactors were dedicated to the nation," Modi said on X.

The next two 700 MWe PHWRs are under construction at Rawatbhata in Rajasthan, and the Indian government has sanctioned the construction of further units at Kaiga in Karnataka; Gorakhpur in Haryana; Chutka in Madhya Pradesh; and Mahi Banswara in Rajasthan.

Seeking investors

According to Reuters, government sources said India was planning to invite private firms to invest some USD26 billion in its nuclear energy sector, and is in talks with "at least" five private firms including Reliance Industries, Tata Power, Adani Power and Vedanta Ltd to invest around INR440 billion (USD5.30 billion) each.

Plans are not yet finalised, but the government hopes to use the investments to build 11,000 MWe of new nuclear capacity by 2040, the sources said. The plants would be built and operated by NPCIL, with the investing companies earning revenue from electricity sales from the plants. This hybrid plan would not require any amendment to India's Atomic Energy Act of 1962 - which prohibits private control of nuclear power generation - but would need to be approved by the Department of Atomic Energy, they said.

Only two government-owned enterprises - NPCIL and Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI, set up to build and operate fast reactors) - are legally allowed to own and operate nuclear power plants in India. But the possibility of involving other public sector and private corporations in the country's future expansion plans is something that has been under consideration for some time. In 2016, the government amended the Atomic Energy Act to allow NPCIL to form joint venture companies with other public sector undertakings India in a move intended to help the state-owned company to secure funding for new projects, although the legislative change did not extend to private sector companies or foreign investors.

As well as further 700 MWe PHWRs, Indian plans envisage the construction of large reactors from overseas vendors, including further Russian-designed VVER reactors in addition to those already in operation and under construction at Kudankulam in Tamil Nadu. In August 2023, Minister of State Jitendra Singh also told the country's parliament that the government was considering options for small modular reactors, and looking at ways to allow the participation of the private sector and start-ups in such projects.

Le chargement du combustible a commencé dans le prototype de réacteur nucléaire à neutrons rapides indien
La mise en service du PFBR, prototype indien de réacteur à neutrons rapides, approche enfin avec le chargement imminent de son combustible. Si tout se passe comme prévu, ce prototype devrait donner naissance à plusieurs réacteurs surgénérateurs, et ainsi permettre le recyclage du combustible usagé de ses réacteurs existants.

Kevin CHAMPEAU 15 Mar 2024

Il était temps ! 20 ans après le lancement des travaux, le PFBR (Prototype Fast Breeder Reactor), prototype de réacteur à neutrons rapides indien, va enfin recevoir son combustible nucléaire pour une mise en service espérée en décembre 2024. Ce réacteur de 500 MWe, développé par le BHAVINI, une entreprise nationalisée sous tutelle du département indien de l’énergie atomique, devait initialement entrer en service en 2010. Mais le projet subit de nombreux retards, jusqu’à en faire le plus long projet de réacteur nucléaire de l’histoire.

Une fois mis en service, ce réacteur rejoindra la très courte liste des réacteurs à neutrons rapides en fonctionnement dans le monde avec les réacteurs russes Beloyarsk-3 (560 MWe) et Beloyarsk-4 (820 MWe), et le CEFR chinois (20 MWe).


L’Inde mise sur un programme nucléaire en trois étapes

Pourtant, la technologie des réacteurs à neutrons rapides intéresse depuis très longtemps. Et pour cause, cette technologie permet d’utiliser la quasi-totalité de la ressource uranium, de mieux recycler les combustibles usagés issus des autres réacteurs, et donc réduit la quantité de déchets ainsi que leur radiotoxicité. Néanmoins, on dénombre huit réacteurs à l’arrêt dans le monde aux États-Unis, au Royaume-Uni, en France (Phénix et Superphénix) ou encore au Japon. Cette technologie présente un inconvénient majeur : elle nécessite un circuit de refroidissement au sodium liquide, un matériau inflammable au contact de l’air et réagissant violemment au contact de l’eau. De ce fait, elle est difficile à maîtriser, ce qui a conduit à un incident nucléaire important en 1995, dans la centrale japonaise de Monju.

Malgré ces difficultés, l’Inde y croit quand même. Après avoir construit de nombreux réacteurs à eau pressurisée et à eau lourde pressurisée, le pays s’attaque donc à la deuxième étape de son programme nucléaire qui consiste à déployer des réacteurs à neutrons rapides qui pourront utiliser les déchets nucléaires des premiers réacteurs. Le PFBR sera alimenté avec du MOX, un combustible nucléaire constitué de 8,5 % de plutonium et 91,5 % d’uranium appauvri. Grâce à l’expérience acquise avec ce prototype, le pays espère construire 6 réacteurs commerciaux d’une puissance de 500 MWe.

La troisième étape du programme nucléaire indien consistera, à terme, à construire des réacteurs avancés à eau lourde (AHWR) qui seront capables de fonctionner avec un mélange de plutonium et de thorium, une ressource que l’Inde possède en grande quantité.

India Looks to Russia for Reliable Uranium Supply

By Alex Kimani - Jul 12, 2024

For the first time in five years, Indian Prime Minister Narendra Modi landed in Russia for a state visit on Monday, where he is holding talks with President Vladimir Putin to help re-energize relations between the two countries, with an eye on strategic deals. One item on the top of the agenda is Modi’s desire to finalize a long-term uranium supply deal with Russia, in a bid to secure a stable and reliable source of uranium for India's expanding nuclear power sector.

It would be a big score for both India and Russia, and Washington is paying attention closely because India is the key element of the U.S. plan to contain China, first and foremost, and Russia, secondarily. Modi can influence them both. India already gets a pass on Russia oil and gas sanctions, and Washington will have little choice other than accept the same for Russian uranium.
The two allies are likely to agree on a long-term uranium supply pact for a nuclear power plant coming online in Tamil Nadu, said senior officials with knowledge on the matter. Cooperation in the civilian nuclear sphere doesn’t fall under the sanction regime by the U.S. and its western allies for Russia’s war on Ukraine. Russia’s state nuclear company Rosatom previously supplied nuclear fuel to India’s Kudankulam nuclear plant in 2022 and 2023.

“Kudankulam Nuclear Power Plant units 1 and 2 have already become operational, and the work is progressing on units 3 and 6,” India’s Foreign Secretary Vinay Kwatra said on Friday, adding that Moscow “remains an important partner for India’s energy security and defense.”

Currently, India gets the bulk of its uranium from mines in the northern state of Jharkhand. Unfortunately, the state’s uranium reserves are fast depleting while efforts to exploit deposits in other states such as Andhra Pradesh and Meghalaya have failed to meet expectations thus forcing the country to increasingly rely on imports. India currently relies on spot deals for the procurement of the fuel with nations including Kazakhstan, France, Russia, Canada and Uzbekistan.

ROSATOM starts implementation of fuel supply contract to India for Kudankulam units 3 and 4
During the operation of the power units 1 and 2 of the first stage of Kudankulam NPP, Russian and Indian specialists have accomplished a large amount of work to improve their efficiency by introducing advanced nuclear fuel and extended fuel cycles

Staff Writer 1st Aug 2024

TVEL Fuel Company of Rosatom has started implementation of nuclear fuel supply contract for units 3 and 4 of the Kudankulam NPP. The contract embraces the entire lifetime of the power units from the starting loading of the reactor cores. Units 3 and 4 of the Kudankulam NPP of the Russian design, powered by VVER-1000 reactors, are under construction in South India.

During the operation of the power units 1 and 2 of the first stage of Kudankulam NPP, Russian and Indian specialists have accomplished a large amount of work to improve their efficiency by introducing advanced nuclear fuel and extended fuel cycles. Since 2022, Kudankulam NPP has been supplied with nuclear fuel of improved design TVS-2M. The new fuel ensures more reliable and cost-efficient operation of reactors due to its rigid skeleton, new-generation anti-debris filter and higher uranium mass. Its introduction also enabled it to increase the fuel cycle of the reactors from 12 to 18 months (i.e. the time of continuous operation of the reactor before shutdown for unloading irradiated fuel and loading fresh fuel). Operation in longer fuel cycles also improves the economic efficiency of NPPs: the power unit is shut down less often for fuel reloading and generates more energy during the year.

“The facilities of the second stage of the Kudankulam NPP will be the first VVER-1000 reactors in history to be launched in an extended 18-month fuel cycle. This is a result of our successful cooperation in recent years, as the efficient solutions which have been previously implemented at similar reactors in Russia and China were also introduced at the Kudankulam operational power units. Throughout the entire NPP life cycle, ROSATOM not only supplies nuclear fuel, but also provides engineering services, improving the efficiency of power units through new solutions for fuel and fuel cycle,” Natalia Nikipelova, President of TVEL Fuel Company, commented.

India's NTPC confirms plans for nuclear subsidiary

20 August 2024

With the groundbreaking for its first nuclear joint venture project expected within the next two months, India’s largest power company has confirmed it intends to set up a nuclear power subsidiary and is actively looking for locations for plants.

NTPC Chairman and Managing Director, Gurdeep Singh told a meeting for analysts and investors at the end of July that India's largest power utility sees nuclear capacity - including small modular reactors (SMRs) - as central to its plans. He said nuclear energy developments were the "most important" of two major developments announced in the budget presented to the Indian Parliament by Minister of Finance Nirmala Sitharaman earlier in July (the other being advanced ultra-supercritical thermal power generation, in which state-owned NTPC is also involved as a joint venture partner).

"We had been working on the nuclear," Singh said. "Our first nuclear power project in Mahi Banswara in Rajasthan is likely to take the activities of groundbreaking in next two months. That is, as you know, that is joint venture with NPCIL. NPCIL is the lead partner; 51(%), we are 49(%).

"But I'm happy to share with all of you that we have already decided to make NTPC Nuclear Power Company, which will be a 100% subsidiary of NTPC. And we are looking forward for different sites in different states."

That search includes Gujarat, Tamil Nadu, Chhattisgarh, Odisha and Karnataka, Singh said in answer to questions. Any site would need Atomic Energy Regulatory Board approval.

NTPC already has a team in place and "would like to repeat the same kind of success story" it had experienced with coal or thermal power stations, he said, adding that the capacity involved will be in the "tens of" gigawatts.

Referring to the plans outlined in the Indian budget to partner with the private sector to set up a company called Bharat Small Reactors, Singh said SMRs provide a "bigger and wider scope" in which NTPC plans to be involved.

"But at this stage you can just take it for granted that already things have started happening. It has taken some time. But now, the things are in place," he said.

Under Indian legislation, only two companies - Nuclear Power Corporation of India Ltd (NPCIL) and Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI, set up to build and operate fast reactors) - are legally allowed to own and operate nuclear power plants in India, but a 2016 amendment to the 1962 Atomic Energy Act allows public sector joint ventures.

State-owned NTPC - short for National Thermal Power Corporation - agreed with NPCIL to form a joint venture for nuclear power plant construction as long ago as 2011, and last year signed a supplementary joint venture agreement for the development of six 700 MWe Indian-designed pressurised heavy water (PHWR) reactors including the four earmarked for construction at Mahi Banswara. These units are amongst a list of ten PHWRs already accorded administrative approval and financial sanction to be built in "fleet mode".

Première divergence d'un réacteur de 700 MW en Inde :
Rajasthan unit reaches first criticality

20 September 2024

Rajasthan Atomic Power Plant unit 7 - India's third indigenously designed 700 MWe pressurised heavy water reactor - achieved first criticality on 19 September after receiving clearance from the Indian nuclear regulator.

Celebrating first criticality at RAPP-7 (Image: NPCIL)

First criticality marks the completion of the construction phase and the start of the operational phase, Nuclear Power Corporation of India Ltd (NPCIL) said. The unit will now undergo various tests before it is connected to the grid. Its power will then be raised, in steps, until it reaches full power - a process known as power ascension testing - with clearance from the Atomic Energy Regulatory Board at each step.

Fuel loading at Rajasthan Atomic Power Plant unit 7 - or RAPP-7 - began on 1 August, and the unit now joins Kakrapar 3 and 4 in India's fleet of 700 MWe pressurised heavy water reactors (PHWRs). Kakrapar 3 achieved first criticality in July 2020, was connected to the grid in January 2021 and was declared to be in commercial operation in July 2023. Kakrapar 4 reached first criticality in late December 2023, was connected to the grid in February and declared in commercial operation at the end of March.

"The successful achievement of criticality of RAPP-7, after the smooth operation of the first two 700 MW PHWRs … at Kakrapar in Gujarat, demonstrated the maturity achieved by NPCIL in the design, construction and operation of the indigenous 700 MW PHWRs," NPCIL said.

The Rajasthan plant is already home to six operating PHWRs with a total capacity of 1180 MW. A second 700 MW PHWR - RAPPS-8 - is also under construction and is expected to start generation next year.

As well as Rajasthan units 7 and 8, four Russian-supplied VVER pressurised water reactors are under construction at NPCIL's Kudankulam site in Tamil Nadu. Site works are also under way for the construction of two 700 MW units Gorakhpur in Haryana. In addition to these, a 500 MWe Prototype Fast Breeder Reactor is being built by BHAVINI at Kalpakkam in Madras.

Ten further 700 MW PHWRs have received administrative approval and financial sanction: Kaiga units 5 and 6 in Karnataka; Gorakhpur units 3 and 4 in Haryana; Chutka units 1 and 2 in Madhya Pradesh; and Mahi Banswara units 1 and 2 and units 3 and 4 in Rajasthan. The Indian government recently approved the transfer of the project to build four 700 MWe PHWRs at Mahi Banswara to NPCIL and National Thermal Power Corporation's Ashvini joint venture.

India welcomes newest Rajasthan unit to the grid

Monday, 17 March 2025

Unit 7 at the Rajasthan Atomic Power Project is the third 700 MWe indigenous pressurised heavy water reactor to be connected to the Indian grid.

The unit - which is also known as RAPP-7 - reached first criticality in September and was connected to the northern grid early on Monday.

"With the clearance from the Atomic Energy Regulatory Board AERB and passing all tests with flying colours, unit 7 is now synchronised with the National Grid," Nuclear Power Corporation of India Ltd (NPCIL) said in a video released to mark the achievement.

Once a new unit has been connected to the grid, it undergoes a process known as power ascension testing when its power levels are gradually raised - under approval from the regulator - until it reaches full capacity. It will then enter commercial operation.

RAPP-7 follows Kakrapar 3 and 4 in a planned fleet of 700 MWe pressurised heavy water reactors (PHWRs): unit 3 achieved first criticality in July 2020, was connected to the grid in January 2021 and was declared to be in commercial operation in July 2023. Unit 4, which reached first criticality in December 2023, was connected to the grid in February and entered commercial operation in March 2024.

"NPCIL has mastered the art of building and operating these reactors," the company said.

A second 700 MWe unit, RAPP-8, is also under construction at the site at Rawatbhata, which is already home to six operating PHWRs with a total capacity of 1180 MW. NPCIL said it expects RAPP-8 to be operational "in 2025-26".

The government has sanctioned the "fleet mode" construction of further 700 MWe units at Kaiga in Karnataka; Gorakhpur in Haryana; Chutka in Madhya Pradesh; and Mahi Banswara in Rajasthan.

Earlier this year, Minister of Finance Nirmala Sitharaman outlined ambitions for the development of at least 100 GW of nuclear energy by 2047 to support India's energy transition efforts. This new capacity would include the development of Indian-designed small modular reactors to be operational by 2033, with amendments to Indian legislation to encourage private sector participation in nuclear projects.
