AB - Nuclide analysis data generated during nuclear decommissioning serves as critical input for radioactive waste classification, regulatory compliance, and worker safety. Following the NSSC's approval of Kori Unit 1 decommissioning in June 2025 and the establishment of the Korea Research Institute of Decommissioning (KRID) in December 2024, ensuring data integrity has become a practical operational requirement. Existing systems, however, lack step-by-step audit mechanisms and remain vulnerable to Harvest Now, Decrypt Later (HNDL) attacks. This study proposes a post-quantum cryptography (PQC)-based digital audit architecture grounded in NIST FIPS 203 (ML-KEM-768) and FIPS 204 (ML-DSA-65), incorporating four core contributions: ① a SHA-3 hash chain-based error tracing mechanism, ② a Regulatory Decision Integrity (RDI) model integrated with NSSC and KINS procedures, ③ a Crypto Agility strategy for decommissioning schedules exceeding 12 years, and ④ a Dynamic Threshold Algorithm (DTA) that distinguishes natural counting fluctuations from intentional manipulation. Experiments across six attack scenarios using IAEA nuclide datasets and ORNL gamma-ray spectra achieved 100% detection rates and 0.00% false positive rates for E3–E6, while DTA reduced the false positive rate from 100% to 0.2% in the E2 noise scenario, with a detection rate of 8.8% in the boundary region (±10%), confirming that a hybrid structure combining DTA with the hash chain is necessary. PQC processing overhead remained within 0.001-0.015% of the batch cycle, while the technical feasibility and applicability of the proposed architecture were preliminarily examined using public nuclide datasets and gamma-ray spectrum-based simulation environments.
