Verification of RiskA calculation engine based on Open-PSA platform

Probabilistic Safety Assessment (PSA) has been widely used in nuclear safety and reliability field in recent years. PSA is playing a positive role in these fields and the analysis programs are also in rapid development, but the model created by one program cannot be used in another, so the results are difficult to be cross verified. A universal method is develped based on Open-PSA platform to solve such problem and is also used to check RiskA calculation engine. Results proves that RiskA is valid and reliable.
