| Title | Nuclear power plants - Instrumentation and control systems important to safety - Requirements for coping with Common Cause Failure (CCF) |
| Project Number | 22259 |
| Abstract/Scope | Gives requirements related to the avoidance of CCF of I&C systems that perform category A functions; additionally requires the implementation of independent I&C systems to overcome CCF, while the likelihood of CCF is reduced by strictly applying the overall safety principles of IEC SC 45A (notably IEC 61226, IEC 61513, IEC 60880 and IEC 60709); gives an overview of the complete scope of requirements relevant to CCF. |
