📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本でもSMRへの関心はあるが、規制・社会的受容性の課題は共通。ブラジルの事例から、長期の国家政策と規制整備の重要性が示唆される。

In the global GX context

Globally, SMRs are gaining attention for decarbonization. This paper provides empirical evidence from a developing country context, highlighting regulatory and capacity-building barriers relevant for many nations considering nuclear options.

👥 読者別の含意

🔬研究者:Provides qualitative insights on SMR barriers and opportunities in a non-OECD context, useful for comparative energy transition studies.

🏢実務担当者:Offers regulatory and partnership models for companies or utilities exploring SMR deployment.

🏛政策担当者:Highlights the need for specific nuclear legislation, capacity building, and stakeholder engagement for SMR adoption.

📄 Abstract(原文)

Small Modular Reactors (SMRs) represent a promising technological innovation for energy transition, offering enhanced safety, operational flexibility, and modularity. This study examines critical success factors for SMR implementation in Brazil’s energy matrix, addressing regulatory, economic, technical, and social dimensions. A qualitative approach combined bibliometric analysis of 190 documents from Scopus with semi-structured interviews of nine Brazilian experts with over 15 years of experience. Results reveal regulatory framework inadequacy was identified by 77.8% of experts as the primary barrier, followed by capacity building needs (55.6%), risk management challenges (55.6%), and economic viability concerns (44.4%). Private sector participation (66.7%) and diverse industrial applications (33.3%) emerged as key opportunities. SMRs can contribute to decarbonization goals and energy security in Brazil, particularly for industrial applications in petrochemical facilities, mining operations, and offshore platforms. Successful implementation requires: (1) continuous state nuclear policy; (2) SMR-specific regulatory frameworks; (3) public-private partnership models; (4) capacity building programs; and (5) transparent communication strategies. This research provides empirical evidence from Brazilian experts and specific recommendations for policymakers, regulators, and industry stakeholders.
