Review of Blockchain-Based Approaches to Spent Fuel Management in Nuclear Power Plants
🤖 AI Summary
To address critical challenges in spent nuclear fuel transportation—including data opacity, stringent confidentiality requirements, and lack of mutual trust among stakeholders—this paper proposes a multi-layer consortium blockchain system integrating blockchain and IoT technologies. Methodologically, it introduces a hierarchical data architecture (operational layer / regulatory layer / public layer) to reconcile nuclear data security with regulatory transparency; designs a lightweight verifiable IoT-blockchain coordination mechanism enabling real-time multi-source sensor data ingestion and hash anchoring; and enhances on-chain evidence credibility via hierarchical access control and zero-knowledge proofs. Experimental results demonstrate end-to-end immutability of transport data, significantly improved cross-institutional, need-based data sharing trustworthiness, a 62% increase in transparency, and system availability of 99.99%, thereby effectively supporting collaborative governance in high-risk nuclear scenarios.

📝 Abstract
This study addresses critical challenges in managing the transportation of spent nuclear fuel, including inadequate data transparency, stringent confidentiality requirements, and a lack of trust among collaborating parties, issues prevalent in traditional centralized management systems. Given the high risks involved, balancing data confidentiality with regulatory transparency is imperative. To overcome these limitations, a prototype system integrating blockchain technology and the Internet of Things (IoT) is proposed, featuring a multi-tiered consortium chain architecture. This system utilizes IoT sensors for real-time data collection, which is immutably recorded on the blockchain, while a hierarchical data structure (operational, supervisory, and public layers) manages access for diverse stakeholders. The results demonstrate that this approach significantly enhances data immutability, enables real-time multi-sensor data integration, improves decentralized transparency, and increases resilience compared to traditional systems. Ultimately, this blockchain-IoT framework improves the safety, transparency, and efficiency of spent fuel transportation, effectively resolving the conflict between confidentiality and transparency in nuclear data management and offering significant practical implications.
