A Web-Based Private Permissioned Blockchain for Ionizing Radiation Management: A Case Study of The Tanzania Atomic Energy Commission

Abstract

The intricate software and hardware configurations of nuclear regulatory systems, such as ionization radiation inspection systems, and maintaining and monitoring their integrity pose challenges. Traditional methods of managing ionization radiation data often lead to vulnerabilities such as data manipulation and inefficiency in handling information, which can result in compromised safety measures and regulatory non-compliance. Recording electronic ionization radiation and related data in spreadsheets or other obsolete systems poses a threat to information security due to accidents. This project addresses the challenges of managing ionization radiation data within nuclear regulatory systems by developing a private permissioned blockchain Management Information System for the Tanzania Atomic Energy Commission (TAEC). The primary objective is to enhance data security, operational efficiency, and regulatory compliance through a secure, immutable, and transparent digital platform. The project employed qualitative data collection methods, including user stories from focus groups with TAEC staff. The system leveraged smart contras (chaincode) to automate processes and enforce rules. It was developed using Hyperledger Fabric and followed the Extreme Programming (XP) methodology. A prototype was implemented to demonstrate the feasibility of this approach, focusing on the general inspection process of ionization radiation sources and facilities. The system successfully automated inspection scheduling, data recording, and report generation reducing processing time from days to hours while improving data integrity, transparency and accessibility. Validation results indicated high user satisfaction, with 94% agreeing on the system's usability and data security. The blockchain framework ensured secure and tamper-proof record-keeping, meeting regulatory standards and enhancing ionization radiation operational workflows at TAEC.
