Slovénie: le premier ministre veut un second réacteur nucléaire

AFP parue le 22 août 2019

Le premier ministre slovène Marjan Sarec a plaidé jeudi pour la construction d'un second réacteur nucléaire sur le site de l'unique centrale que le pays partage avec la Croatie, à Krsko, et dont les opposants dénoncent le vieillissement.

"Nous devons faire tous les efforts nécessaires pour commencer à construire un second bloc car nous aurons besoin de plus d'énergie à l'avenir si nous voulons réussir notre développement", a indiqué le chef du gouvernement lors d'une visite sur ce site, à une centaine de kilomètres de la capitale, Ljubljana.

Le débat sur la construction d'un second réacteur à Krsko est récurrent depuis quinze ans dans l'ancienne république yougoslave mais le gouvernement du Premier ministre de centre-gauche, à la tête d'une coalition minoritaire de cinq partis, n'avait pas inscrit ce projet à son programme.

M. Sarec a justifié sa position par l'absence d'autres alternatives, rappelant l'opposition des groupes de défense de l'environnement et de la société civile aux projets de construction d'éoliennes et de nouvelles centrales hydroélectriques en Slovénie, pays de l'UE qui s'est bâti une image de "nation verte".

Le Premier ministre a promis jeudi de consulter des experts et de chercher le plus large consensus politique pour ce projet "crucial".

Construit à l'époque yougoslave et entré en service en 1983, le réacteur de type Westinghouse de Krsko, d'une puissance de 700 megawatts, devait initialement cesser son activité en 2023, après 40 ans de fonctionnement.

Ljubljana et Zagreb ont toutefois décidé en 2015 de prolonger son activité de vingt ans, malgré les protestations de plusieurs ONG. Il couvre environ 20% des besoins en électricité de la Slovénie et 15% de ceux de la Croatie.

Slovénie: l'unique centrale nucléaire à l'arrêt en raison d'une fuite dans l'enceinte de confinement

AFP le 05 oct. 2023

L'unique centrale nucléaire de Slovénie a été mise à l'arrêt par mesure de précaution jeudi en raison d'une fuite dans l'enceinte de confinement, a indiqué la centrale dans un communiqué.

"Une fuite a été détectée dans le système primaire de l'enceinte de confinement", a expliqué dans un communiqué envoyé à l'AFP la centrale nucléaire de Krsko, située à une centaine de kilomètres à l'est de la capitale slovène et près de la frontière avec la Croatie.

"La mise à l'arrêt est nécessaire pour déterminer la source de la fuite et les mesures nécessaires pour la résoudre", est-il précisé.

Le dernier arrêt préventif de la centrale nucléaire avait été décidé en 2020 après un tremblement de terre en Croatie qui avait fait sept morts.

Construit à l'époque yougoslave et entré en service en 1983, l'unique réacteur de type Westinghouse de Krsko couvre 20% des besoins en électricité de la Slovénie et environ 15% de ceux de la Croatie. La centrale est co-administrée par les deux pays depuis l'éclatement de l'ex-Yougoslavie.

La centrale devait initialement cesser son activité en 2023, après 40 ans de fonctionnement mais les deux pays sont convenus de prolonger sa durée de vie de 30 ans et envisagent la construction d'un deuxième réacteur malgré les inquiétudes suscitées par son âge et les risques sismiques.

Paravan gave the update on the project while speaking at the Energetika 2023 conference.

According to GEN Energy he noted that the company had this year changed the design of the project "so we could build a larger block with a power of up to 2400 MW, or two blocks". This would expand the range of potential suppliers, improving the negotiating power and provide greater co-investment opportunities, he said. It would also increase energy security.

The company reported him as saying "we will treat all three possible technology suppliers for JEK2 - the American Westinghouse, the French EDF and the Korean KHNP - equally" and added that they all have strengths and weaknesses and "the decision will not be easy".

A new working group of Slovenian government ministers and industry officials has been established and met last month with the aim of speeding up the implementation of the JEK2 project and preparing "all the necessary bases for citizens to make high-quality and informed decisions about" it in a referendum which the government says is needed for the project to happen.

The planned timeline is for a final investment decision by 2028, with the aim of new capacity coming online in the 2030s.

Krško, a 696 MWe pressurised water reactor, is Slovenia's only nuclear power plant and generates about one-third of its electricity. The plant, which is co-owned by neighbouring Croatia, began commercial operation in 1981, and a 20-year extension to its initial 40-year operational lifetime was confirmed in mid-2015. Krško is owned and operated by Nuklearna Elektrarna Krško, which is jointly owned by Croatia's Hrvatska elektroprivreda (HEP Group) and Slovenia's GEN Energija.

EDF fait des propositions à la Slovénie pour son programme nucléaire

AFPparue le 30 nov. 2023

EDF a annoncé jeudi avoir soumis à la Slovénie des propositions "technico-commerciales" pour la construction éventuelle d'un réacteur de type EPR voire deux.

Le groupe a aussi signé, lors du salon du nucléaire civil WNE organisé près de Paris, des accords de coopération avec des entreprises de Pologne et d'Italie, après l'Inde, le Canada et la Tchéquie.

Pour la Slovénie, l'électricien français a remis sa proposition au président du groupe Gen Energija, avec qui il mène "des discussions actives depuis 2019 pour le développement du programme +nouveau nucléaire+ slovène".

Son offre concerne la construction d'un EPR ou de deux réacteurs de moyenne puissance de type EPR1200.

Le projet vise à équiper la centrale de Krsko, située à une centaine de kilomètres à l'est de Ljubljana et près de la frontière avec la Croatie. Aucun calendrier n'a été communiqué.

La centrale accueille depuis 1983 l'unique réacteur du pays, de technologie américaine Westinghouse. Le site, qui fournit en électricité la Slovénie et la Croatie, est co-administré par les deux pays. Ce réacteur devait cesser son activité en 2023, mais Ljubljana et Zagreb sont convenus de prolonger sa durée de vie de 30 ans.

Pour EDF, "l'inclusion du projet slovène dans la flotte d'EPR actuellement en construction en Europe apporterait des avantages réciproques certains tout au long de la durée de fonctionnement des futures centrales".

La Slovénie va organiser un référendum sur un second réacteur nucléaire

AFP le 30 janv. 2024

Le gouvernement slovène, qui envisage la construction d'un second réacteur dans l'unique centrale nucléaire du pays, va soumettre la question aux citoyens par le biais d'un référendum.

"Nous avons tous convenu que le chemin vers une société décarbonée passe par des sources d'énergie renouvelables d'un côté, l'énergie nucléaire de l'autre", a déclaré le Premier ministre Robert Golob lors d'une conférence de presse mardi.

"Pour un projet aussi important - en terme de coût et parce qu'il engage l'avenir du pays -, il nous faut parvenir à un consensus", a-t-il ajouté à l'issue d'une réunion avec l'ensemble des partis politiques.

Si les responsables des différents bords se sont mis d'accord, il faut désormais l'aval des près de deux millions d'électeurs. Un référendum sera donc organisé au second semestre, a précisé M. Golob.

L'ex-Premier ministre Janez Jansa, à la tête du parti d'opposition conservateur SDS, a salué cette décision de nature à "accélérer le processus de construction d'un second réacteur".

Les autorités avaient délivré en 2021 un permis pour ce réacteur qui pourrait avoisiner une puissance maximale de 2.400 mégawatts, selon le chef du gouvernement.

Le groupe français EDF avait dit en novembre avoir présenté à la Slovénie des propositions "technico-commerciales" pour la construction éventuelle d'un réacteur de type EPR.

Les noms de l'américain Westinghouse et du coréen KHNP ont aussi été évoqués.

Cette nouvelle unité doit venir compléter la centrale de Krsko. Située en Slovénie près de la frontière avec la Croatie, elle est co-administrée par les deux pays depuis l'éclatement de l'ex-Yougoslavie, couvrant environ 20% des besoins en électricité de la Slovénie et 15% de ceux de la Croatie.

Entré en service en 1983, l'unique réacteur de type Westinghouse devait initialement cesser son activité en 2023 mais il a obtenu les autorisations nécessaires à une prolongation d'activité de 20 ans.

Estimated cost for JEK2 options put at EUR9.4 billion-15.4 billion

24 May 2024

GEN energija has given its latest update on the development of plans for the JEK2 new nuclear capacity in Slovenia, putting forward likely costs and saying that from the point of view of the power network 1300 MW would be the optimal size.



How JEK2 could look (Image: GEN energija)

GEN energija said that its "best internal assessment" - and not based on binding offers from potential suppliers - was overnight construction costs of EUR9300 per kW of installed power: "This means EUR9.3 billion (USD10.1 billion) for a power plant of 1000 MW and EUR15.4 billion for a power plant of 1650 MW. For all calculations and used assumptions, we intend to obtain an international review by a recognised institution before the referendum is held."

In a report of the briefing, GEN energija said its study of the country's power system considered options from 1000 MWe to 2400 MWe - "the key findings are that from the point of view of safety and stability" of the country's power network "the optimal size of JEK2 is up to 1300 MW of net electric power ... and that new sources of balancing system services are needed, especially resources to ensure the manual reserve for frequency recovery".

GEN Energija says the project is of "exceptional strategic importance" enabling decarbonisation and energy security for 80 years or more. It also estimates there will be an estimated 5640 new jobs in 10 years as well as more than 37% share of domestic suppliers for the project.

Slovenia's plan is to build the new nuclear power plant, with up to 2400 MW capacity, next to its existing nuclear power plant, Krško, a 696 MWe pressurised water reactor which generates about one-third of the country's electricity and which is co-owned by neighbouring Croatia. Prime Minister Robert Golob has committed to holding a referendum on the project before it goes ahead, and has suggested it could be held later in 2024.

The current timetable for the project is for a final investment decision to be taken in 2028, with construction beginning in 2032. In October, GEN Energy CEO Dejan Paravan said there were three technology providers being considered for the project - Westinghouse, EDF and Korea Hydro & Nuclear Power - who all had strengths and "the decision will not be easy".

There was a further boost for the project on Thursday when Slovenia's National Assembly passed a resolution on the long-term peaceful use of nuclear energy, including the JEK2 project and the proposal for a referendum.

GEN energija favours large units over SMRs for Slovenia's JEK2

29 August 2024

Reports on flood safety, nuclear fuel supplies, radioactive waste disposal and also an overview of small modular reactors as an option have been published by GEN energija as part of public information measures ahead of Slovenia's referendum on planned new nuclear.


How JEK2 could look (Image: GEN energija)

Slovenia's JEK2 project is for a new one or two-unit nuclear power plant, with up to 2400 MW capacity, next to its existing nuclear power plant, Krško, a 696 MWe pressurised water reactor which generates about one-third of the country's electricity and which is co-owned by neighbouring Croatia.

Prime Minister Robert Golob has committed to holding a referendum on the project before it goes ahead, and has suggested the vote could be held later in 2024, with eight key studies and documents to be published beforehand to "enable citizens to make an informed decision". The current timetable for the project is for a final investment decision to be taken in 2028, with construction beginning in 2032.

A report published on Thursday on the JEK2 project website praises the potential of small modular reactors (SMRs) but estimates that "in order to compensate for the lack of economies of scale, SMR plants will need to fully exploit the potential benefits of series production in the future. We estimate the time needed to establish serial production and supply chains to be at least 20 years".

It adds: "The analysis of the comparison of the projected timeline of the JEK2 project with the projected development of SMR reactor technology showed that at the time of the expected signing of the contract with the supplier (2028), only three land-based SMR reactors will be in commercial operation, and an additional three will be under construction. All these reactors are FOAK (first of a kind) projects ... although the use of SMR technology for the JEK2 project is not suitable in the desired time frames, the GEN Group will continue to intensively monitor the development of SMR reactor technology."

In its latest broader update to reporters the company said the flood safety study showed that floods lower than the maximum possible level would not threaten the planned location of the JEK2 plant, but a further study taking into account a 10,000-year flood and the measures proposed to ensure flood safety of the heart of the site is being commissioned.

The report on the financial and safety aspects of the import of nuclear fuel concluded that "nuclear fuel represents a relatively small share of the cost price of electricity compared to power plants powered by liquid, gaseous or solid fossil fuels" and "Slovenia's reliable supply of nuclear fuel is ensured by its membership in the Euratom community. One of the fundamental objectives of the community is to ensure a regular and equal supply of nuclear fuel and other nuclear materials to all users in the EU, which also includes the control of the materials".

It adds that "Based on current annual uranium requirements, the identified resources are sufficient for more than 130 years. If all conventional and non-conventional resources were exploited, the time for which known reserves are sufficient would be extended to over 300 years."

The assessment on dealing with radioactive waste and used nuclear fuel notes that the country can build on its existing processes and adds that by the time the JEK2 project is completed, facilities for the disposal of such materials will already be built and established, "but their disposal capacities will have to be increased accordingly".

The company also covered the proposed cost of the project, noting that although Korea Hydro & Nuclear Power's 1000 MWe reactor in the Czech Republic had a projected cost of EUR7.9 billion (USD8.8 billion), the assessment in Slovenia was that the same sized reactor would cost about EUR9.3 billion. It added: "An international review is under way, which will check all calculations and used economic assumptions."

GEN energija is also conducting an information roadshow across the country to present information and answer questions about the proposed project. There is also a dedicated jek2.si website, where the various reports are published.

La Slovénie construira finalement son second réacteur nucléaire sans passer par un référendum consultatif

AFP le 24 oct. 2024

La Slovénie, qui envisage la construction d'un second réacteur dans l'unique centrale nucléaire du pays, a renoncé à soumettre la question aux citoyens par le biais d'un référendum, selon un vote jeudi du Parlement.

Le scrutin annulé par les députés

Les autorités ont délivré en 2021 un permis pour cette nouvelle unité qui doit venir compléter la centrale de Krsko. Un référendum, à valeur purement consultative, était prévu le 24 novembre pour valider sa construction. Mais 69 députés sur les 90 du Parlement ont approuvé un décret annulant le scrutin.

Ce texte soulève "des doutes quant à la capacité des électeurs à se prononcer de manière correcte, indépendante et responsable sur un enjeu national majeur de long terme".

Les mêmes partis qui avaient souhaité un référendum ont finalement fait marche arrière devant l'issue incertaine du vote, après des critiques sur le manque de transparence formulées notamment par des associations écologistes.

Un soutien tombé à moins de 60% selon un sondage

Le soutien de la population a faibli ces derniers mois, tombant à moins de 60% selon un sondage publié par le quotidien Dnevnik, contre 68% en janvier.

Le projet, estimé à 15 millions d'euros, va désormais aller de l'avant avant un possible référendum en 2027 et 2028 une fois tous les détails connus, a précisé le Premier ministre libéral Robert Golob.

La centrale de Krsko, située en Slovénie près de la frontière avec la Croatie, est co-administrée par les deux pays depuis l'éclatement de l'ex-Yougoslavie, couvrant environ 20% des besoins en électricité de la Slovénie et 17% de ceux de la Croatie.

Entré en service en 1983, l'unique réacteur de type Westinghouse devait initialement cesser son activité en 2023 mais il a obtenu les autorisations nécessaires à une prolongation d'activité de vingt ans.

Westinghouse and EDF in running for Slovenia unit, KHNP not bidding

30 January 2025

Westinghouse Electric Company and EDF are each to conduct a Technical Feasibility Study for GEN energija assessing the deployment of their reactors at the proposed new nuclear power plant next to the existing Krško site.


Slovenia's JEK2 project is for a new one or two-unit nuclear power plant, with up to 2400 MW capacity, next to Krško NPP which has a 696 MWe pressurised water reactor generating about one-third of the country's electricity. Krško is owned and operated by Nuklearna Elektrarna Krško, which is jointly owned by Croatia's Hrvatska elektroprivreda (HEP Group) and Slovenia's GEN Energija.

The JEK2 project team, following discussions with potential nuclear power plant providers EDF, Korea Hydro & Nuclear Power (KHNP) and Westinghouse, in May last year, estimated the cost for various reactor sizes, ranging from EUR9.314 billion (USD10.1 billion) for a 1000 MW unit, up to EUR15.371 billion for a 1650 MW unit.

At a press conference on Wednesday Bruno Glaser, GEN energija's JEK2 project manager, said that the Technical Feasibility Studies for the two bidders would cost about EUR8.3 million and would assess the technical and legislative requirements and a range of safety and implementation aspects covering construction and operation. The aim of such a study was to ensure "that the project is planned based on realistic technical possibilities and in accordance with the highest safety and technological standards".

According to the company's briefing "the originally planned third bidder, the Korean company KHNP, informed GEN that it will not submit a bid for the preparation of the study and will not participate in the submission of a bid for the construction of the JEK2 project. Their decision is based on an assessment of the current business environment and a change in their strategic business priorities".

Dan Lipman, President of Westinghouse Energy Systems, said: "Since delivering the first Krško unit, which has operated very successfully since it started operating in 1983, Westinghouse has built a decades-long partnership with GEN energija through operational and fueling support. We are pleased to extend the relationship to closely study the feasibility of the Krško-II project. This potential AP1000 project will not only provide clean, reliable baseload power to Slovenians, it will also deliver real economic benefits and high-quality jobs for years to come while fostering Slovenia’s energy independence."

Westinghouse describes the AP1000 as "the only operating Generation III+ reactor with fully passive safety systems, modular construction design and the smallest footprint per MWe on the market". There are six AP1000 reactors in operation - including Vogtle 3 and 4 in the USA - plus 12 under construction and five more under contract, with AP1000s selected for nuclear programmes in Poland, Ukraine and Bulgaria. It said it had teamed up with Hyundai Engineering & Construction to conduct the Slovenian Technical Feasibility Study.

Slovenia had been due to hold a referendum on new nuclear in November, but that was called off amid a political row over how it was being conducted. Prime Minister Robert Golob said he remained committed to holding a referendum before a final investment decision is taken - which is currently due to be in 2028.

GEN energija said that in 2025 it will also continue to prepare professional studies, namely site safety analysis reports, radiological analyses, flood studies, seismic safety studies and technical feasibility studies. It also said it would be carrying out a pre-feasibility study for the construction of small modular reactors in the country.

Last year Westinghouse, EDF and KHNP were the three bidders for new nuclear in the Czech Republic. KHNP was the winning bidder and an EPC contract is expected to be signed by the end of March, despite EDF and Westinghouse appealing against the decision. Since then it has been announced that Westinghouse and KHNP and Korea Electric Power Cooperation have reached agreement on intellectual property issues - the subject of court cases in the USA - and while details regarding the terms of the settlement remain confidential the companies said "the agreement also sets the stage for future cooperation between the parties to advance new nuclear projects globally".

Westinghouse to conduct feasibility study for AP1000 reactor in Slovenia
The study will assess the feasibility of installing a single AP1000 nuclear reactor at the proposed Krško-II Nuclear Power Plant.

Aninda Chakraborty 31st Jan 2025

Westinghouse Electric Company has signed a contract with Slovenia’s state-owned power utility, GEN energija, to conduct a Technical Feasibility Study (TFS) on the potential deployment of an AP1000 reactor as part of the country’s nuclear expansion strategy.

Hyundai Engineering & Construction Company will collaborate with Westinghouse on the study.

The study will assess the feasibility of installing a single AP1000 nuclear reactor at the proposed Krško-II Nuclear Power Plant. The Krško-II project is planned for a site adjacent to the existing Krško Nuclear Power Plant, which was originally developed using Westinghouse technology. This initiative marks a significant step in Slovenia’s efforts to strengthen energy security and reduce dependence on foreign energy sources.

Westinghouse Energy Systems president Dan Lipman said: “Since delivering the first Krško unit, which has operated very successfully since it started operating in 1983, Westinghouse has built a decades-long partnership with GEN energija through operational and fueling support. We are pleased to extend the relationship to closely study the feasibility of the Krško-II project.

“This potential AP1000 project will not only provide clean, reliable baseload power to Slovenians, it will also deliver real economic benefits and high-quality jobs for years to come while fostering Slovenia’s energy independence.”

The AP1000 reactor is the only operational Generation III+ reactor featuring fully passive safety systems, a modular construction design, and the smallest footprint per megawatt of electricity (MWe) on the market. Currently, six AP1000 reactors are in operation worldwide, setting performance and availability benchmarks. An additional 12 reactors are under construction, with five more under contract. By the end of the decade, a total of 18 units based on AP1000 technology are expected to be operational globally.

Westinghouse’s AP1000 technology has also been selected for nuclear energy projects in Poland, Ukraine, and Bulgaria and is under consideration at multiple sites across Europe, the UK, India, and North America.
