NSS-17 + NSS-42-G require physical protection + lifecycle management + safety/EP integration. Physical protection of CBS: equipment in secure compartments + control rooms + protected areas per CSL (CSL 1 in Vital Area or Inner Area per physical protection); controlled access + tamper-evident seals + intrusion detection + alarm + CCTV + access logs; environmental controls (climate + power + uninterruptible power supply + grounding + EMI shielding + fire protection + flooding mitigation); cabling protected + conduit + tamper-evident + segregated from CSL boundaries; spare parts secured + traceability. Coordinates with NSS-13 Physical Protection + NSS-27-G nuclear material security. Lifecycle management: cradle-to-grave for CBS from acquisition + commissioning + operation + maintenance + modification + decommissioning + disposal; secure disposal of media + components + cryptographic devices (sanitisation per IEC 21964 / NIST SP 800-88 + degaussing + physical destruction for CSL 1); decommissioning per Regulatory Body approval + IAEA safeguards + asset disposal trail. Interfaces with Safety + Emergency Preparedness (EP): safety system integrity preserved + cyber-induced safety event prevention; emergency system availability + Auxiliary Feedwater System (AFW) + Emergency Diesel Generator (EDG) + Containment Spray + Emergency Core Cooling System (ECCS) cyber-protected; coordination with GSR Part 7 Emergency Preparedness + GSR Part 4 Safety Assessment + SSR-2/1 Safety of NPPs Design + IAEA SSG-39 Design of I&C Systems for NPPs; cyber-induced reactor trip + safety actuation; cyber attack as Initiating Event in Probabilistic Safety Assessment (PSA). NSS-17/42-G + Physical + Lifecycle + Decommissioning + Safety + EP applies.
