| PMS Requirements | Key Details |
| Redundancy | Segmented, multiple redundant protection groups, sufficient redundancy for connections between redundant divisions in all working conditions. |
| Independence | Independence for multiple channels inside the system, between 1E system and N1E system, other 1E system with physical separation, electric and communication isolations. |
| Diversity | To resist CCF. |
| Simplification | Less equipment, types, interactions, simple software languages. |
| Failure Safe | Failure will not prevent the safety actions or degrade system to unacceptable level. |
| Single Failure Criteria | Capability to perform safety functions concurrent with single failure. |
| Testability | Testability under conditions of power operation and shutdown. No lifting or jumpers required. |
| Self-Diagnostics | Self-Diagnostics, communication check, data integrity validation and calibration for analog input channels. |
| Operability | Checking the operational availability and assuring operational availability |
| Communication | Reliability of communications shall not lower than other parts. |
