2020 – Assystem delivers the ITER tokamak building on schedule, demonstrating its capability in large‑scale nuclear‑fusion projects and establishing a track record that underpins its later nuclear‑plant consulting work [1].

2023 – Croatia establishes a Working Group for Nuclear Energy to evaluate small modular reactors versus large reactors, laying groundwork for future domestic nuclear capacity decisions [2].

2024 – GEN Energija publishes an economic study estimating €9.314 billion for a 1,000 MW unit and €15.371 billion for a 1,650 MW unit at Krško, informing Slovenia’s cost assumptions for the JEK2 project [3].

Feb 2026 – Assystem Deputy CEO Aurélien Aubarbier outlines that “the overall schedule from contract to grid connection is 100‑140 months” and stresses that “funding hinges on proven technology and loan length,” setting a benchmark for new nuclear builds worldwide [1].

Feb 2026 – The Croatian government forwards a draft nuclear‑energy law to parliament, targeting at least 30 % of the national power mix from nuclear by 2040 and mandating civil‑nuclear planning within six months of adoption and a full development plan within twelve months [2].

Feb 2026 – Slovenia’s Prime Minister Robert Golob says the site, likely price and reactor type for a new Krško unit will be known by the time the postponed public vote occurs, signalling concrete progress toward a second reactor at the joint plant [3].

Mid‑2026 (by Aug 2026) – Under the Croatian law, the responsible minister must begin civil nuclear planning, initiating feasibility studies and stakeholder engagement to meet the six‑month deadline [2].

Early‑2027 (by Feb 2027) – Croatia must present a comprehensive nuclear development plan, outlining technology choice, financing and timeline, as required by the new legislation [2].

Late 2027 / Early 2028 – Slovenia schedules a public referendum on the new Krško unit, presenting voters with the chosen location, construction conditions, supplier and final price, making the decision a pivotal step for the project’s financing and timeline [3].

Autumn 2028 – Slovenia expects to adopt the National Spatial Plan for the Krško expansion, finalising siting and regulatory parameters that will guide the subsequent investment decision [3].

2029 – Slovenia aims to reach a Final Investment Decision (FID) for the JEK2 project, committing capital based on the financing model that could affect up to half of nuclear electricity costs, as highlighted by the Ministry of Finance [3].

2033 – Construction of the new Krško unit is slated to begin, marking the transition from planning to physical build‑out for the joint Croatia‑Slovenia nuclear venture [3].

2040 – Croatia targets nuclear power to supply at least 30 % of its electricity, a milestone that will reshape its energy security and low‑carbon strategy [2].

2041 – The new Krško reactor is projected to enter commercial operation, adding up to 2,400 MW of capacity and potentially doubling the current nuclear contribution to Croatia’s power mix [3].

2050 – France’s nuclear strategy aims to triple nuclear capacity by this year, driving aggressive construction targets such as the 70‑75 month EPR2 schedule and influencing global financing expectations for nuclear projects [1].

End of the 21st century – Commercial electricity from fusion is expected to become viable, a long‑term horizon that frames Assystem’s ongoing work on ITER and future fusion start‑ups [1].
