本論文はスロバキアの原子力開発が2050年までのエネルギー安全保障に与える影響を、混合手法（電力バランス再構成、2040年シナリオ比較、1200MW大型炉と300MW SMRのストレステスト）で評価する。2024年に純電力輸出国へ転じた一方、消費は2021年比3.1TWh減。2040年には原子力が総発電の約55%を占める見通しだが、追加炉の貢献は資金調達・許認可・燃料多様化・系統柔軟性・廃棄物ガバナンス等に条件付きで、単一プロジェクト戦略より多様化経路が頑健と結論づける。
English
This paper evaluates how nuclear development affects Slovakia's energy security to 2050 using a mixed-method design: electricity-balance reconstruction, comparison of three 2040 adequacy scenarios, and stress tests for a 1200 MW reactor and 300 MW SMR. Slovakia became a net exporter in 2024, with nuclear projected at ~55% of 2040 generation. Additional nuclear is conditional on financing, licensing, fuel diversification, grid flexibility, and waste governance; a diversified pathway is more robust than a single-project strategy.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はGX推進と原子力再稼働・SMR実証を進めており、電源多様化とエネルギー安全保障の条件付き評価は、第7次エネルギー基本計画やGX2040ビジョンの議論に示唆を与える。特にSMRの経済性・系統柔軟性・廃棄物ガバナンスの論点は国内政策と共通する。
In the global GX context
As global disclosure frameworks (ISSB, TCFD) increasingly require transition plans, this study offers a granular, scenario-based method for assessing nuclear's conditional role in energy security—relevant to EU taxonomy alignment and transition finance debates beyond Slovakia.

📄 Abstract（原文）
This article evaluates how nuclear energy development may affect energy security and nuclear energy security in Slovakia up to 2050. It applies a qualitative-dominant mixed-method design combining critical source-position appraisal, a claim-evidence matrix, quantitative reconstruction of the 2021–2024 electricity balance, comparison of three official 2040 adequacy scenarios, stress tests for a 1200 MW large reactor and a 300 MW small modular reactor (SMR), and negative-case analysis. The results show that Slovakia entered 2024 as a net electricity exporter after Mochovce Unit 3 increased nuclear generation, while electricity consumption remained 3.1 TWh below 2021. The decline from 2021 to 2022 reflected a combination of the energy-price shock, industrial demand curtailment, lower fossil generation and hydrological variability rather than a single structural factor. Official 2040 scenarios project gross generation of 43.9–48.5 TWh, of which nuclear contributes 24.2–26.7 TWh, approximately 55%. Adding a 1200 MW unit would generate about 8.4–10.0 TWh annually at capacity factors of 80–95%, creating a material need for demand growth, exports, storage, nuclear heat, hydrogen or load-following operation. The analysis therefore does not treat the Bohunice project or SMRs as inevitable. Their contribution to energy security is conditional on financing, licensing, fuel diversification, grid flexibility, heat off-takers, climate-resilient cooling, radioactive-waste governance, workforce continuity and transparent public governance. A diversified pathway combining safe long-term operation of existing units, renewables, wind development, storage, demand response and selective nuclear investment is more robust than a single-project strategy.
