中国が2024〜25年に原子力で技術輸入国から第4世代炉の量産国へ転換した実態を分析。2022〜25年に40基超が認可され、世界初の商業用高温ガス炉Shidaowan-1が稼働したが、第14次五カ年計画の70GW目標は建設サイクルの遅延で未達（実績約60GW）となる見通し。国有低利融資（1.4%）が発電コストを70USD/MWhに抑え、西欧の105〜160USD/MWhに対する優位性を生む。高温ガス炉によるピンク水素や地域熱供給（Nuanhe-1）への統合利用が進む一方、使用済燃料再処理能力・ウラン輸入依存・内陸立地モラトリアムが課題。
English
Analyzes China's shift from nuclear technology importer to serial builder of Gen IV reactors in 2024–25. Over 40 units were approved in 2022–25 and the world's first commercial HTR-PM (Shidaowan-1) started up, yet the 14th Five-Year Plan's 70 GW target will be missed (~60 GW actual) due to construction-cycle inertia. Low-cost state lending (1.4%) yields generation costs of USD 70/MWh versus USD 105–160/MWh in the West. Integrated uses—pink hydrogen from high-temperature reactors and district heating (Nuanhe-1)—are emerging, while spent-fuel reprocessing capacity, uranium import dependence, and the inland siting moratorium remain constraints.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策にとって、中国の国営低利融資による原発コスト優位性と水素・熱供給への統合は、日本の原子力再稼働・水素戦略の競争条件を考える上で示唆に富む。SSBJ開示の観点では、原子力の低炭素電源としての位置づけを投資家がどう評価するかの参照材料になる。
In the global GX context
Adds to global transition-finance and disclosure scholarship by quantifying how state-backed financing (1.4% lending) shapes nuclear LCOE and competitiveness against Western projects—relevant to ISSB/TCFD discussions of transition risk and to hydrogen and industrial-decarbonization pathways. It also illustrates a state-led model of Gen IV deployment that contrasts with market-based Western nuclear finance.

📄 Abstract（原文）
The relevance of the study is determined by the transformation of global nuclear energy in the mid-2020s, with China becoming its central actor as it has moved from importing technologies to the serial construction and deployment of Generation IV reactors. The aim of this study is to identify the key trends in the development of China’s nuclear industry in 2024–2025, assess the feasibility of achieving the targets of the 14th Five-Year Plan, and analyze China’s strategic transition towards technological leadership. The study draws on data from the World Nuclear Association, reports of the China Nuclear Energy Association, the strategic document Beautiful China 2035, and analytical reviews by the Information Technology and Innovation Foundation (ITIF) and Global Energy Monitor. Comparative and retrospective analysis, as well as scenario forecasting, were employed. The results show that, despite the record approval of 40+ power units in 2022–2025 and the commissioning of the world’s first commercial Gen IV NPP Shidaowan1 (HTRPM), the planned target of the 14th Five-Year Plan (70 GW by 2025) will not be achieved on time due to the inertia of the construction cycle (actual ~60 GW). China has completed the localization of Hualong One technology and is moving towards the integrated use of nuclear energy, including the production of pink hydrogen using high-temperature reactors and the development of district-heating systems, such as the Nuanhe-1 project. The economic advantage is ensured by lowcost state lending (1.4 %), which reduces the cost of electricity generation to USD 70/MWh, compared with USD 105–160/MWh in Western countries. The main challenges remain insufficient spent nuclear fuel reprocessing capacity, dependence on uranium imports, and the continued moratorium on inland NPP construction. Thus, by 2035, China’s nuclear energy will transform from an electricity source into a universal lowcarbon platform for industry; however, the strategy’s implementation requires accelerated closing of the nuclear fuel cycle.
