APPLICATION OF THE SIMULATION BASED RELIABILITY ANALYSIS ON THE ASSESSMENT OF THE CRITICAL THROUGH WALL CRACK STABILITY
Pečínka L., Švrček M.
pages 459 - 462, full text

Specific feature of the nuclear power plants is in comparison with coal fired plants the break postulation of each high energy piping. Fluid system is considered as high-energy piping if the maximum operating temperature exceeds 100°C and the maximum operating pressure exceeds 2MPa. Based on the progress of the linear fracture mechanics US NRC approved deterministic „leak before break“ methodology. If the defined requirements are met, the break postulation may be canceled. The first step is the assessment of the through wall critical length lcrit. Using the Simulation Based Reliability Analysis approach all uncertainties in the input data of lcrit are in the paper analyzed and the related probability of pipe failure is predicted.
