原子力規制行政に関する現状と課題について

Summary

Japan faces significant challenges in its nuclear regulatory administration, including prolonged safety reviews for new regulatory standards, issues surrounding the extension of reactor operating periods, and the ongoing decommissioning and contaminated water management at the Fukushima Daiichi Nuclear Power Plant. In response, the Nuclear Regulation Authority (NRA) was established in September 2012, separating nuclear promotion from regulation. The NRA implements unified regulatory affairs, including developing and enforcing new safety standards, introducing a 'backfit' system for existing facilities, and setting reactor operating period limits to ensure safety. While progress has been made with some reactors receiving approval for restart or operating period extensions, many still face delays due to ongoing reviews or unaddressed safety measures.
