| 1.2.12-OPB-001-15 | Limits established for design-basis accidents shall not be exceeded for postulated initiating events with the single-failure criterion applied (any one independent failure). | 1.0 (15) | Active | NP-001-15 (General Safety Provisions for Nuclear Power Plants) |
| 3.1-SP-13.13130 | The nuclear plant shall meet fire safety requirements: radiological consequences of a fire shall remain within established limits and personnel shall be protected. | 1.0 (2009) | Active | SP 13.13130.2009 (Nuclear Power Plant Fire Safety Requirements) |
| 3.2-SP-13.13130 | A set of organizational and engineered fire safety measures shall be developed for the plant, including protection of systems important to safety against fire hazards. | 1.0 (2009) | Active | SP 13.13130.2009 (Nuclear Power Plant Fire Safety Requirements) |
| 3.3-SP-13.13130 | Fire safety measures shall provide safety system redundancy, separation of trains by fire barriers, and prevention of fire spread and dispersion of radioactive material. | 1.0 (2009) | Active | SP 13.13130.2009 (Nuclear Power Plant Fire Safety Requirements) |
| 1.7.4-NP-006-98 | The plant fire safety concept shall be presented in the Safety Analysis Report, including principles and criteria for fire prevention and protection against fire consequences. | 2.0 (98) | Active | NP-006-98 (Safety Analysis Report Requirements for VVER Nuclear Power Plants) |
