Evaluation of LOCA Frequency using Alternative Methods
The report presents two different models for derivation of plant specific frequency, in case of Loss of Coolant Accident (LOCA), using specific data from Goesgen NPP, as well as data from the OPDE-database. The first model is using the EPRI methodology of pipe section, and the second model is using the Markov modelling for piping reliability assessment.
For both methods, the pipe boundaries are considered to be ASME Class 1 pipes, with diameters between 10 and 750 mm.
The information gathered provides valuable insights with respect to Goesgen pipe reliability and can be used for different applications, as for example the evaluation of LOCA or the frequency of internal floods. The information gathered also provides insights with respect to evaluation of the efficiency of the plant-specific ageing management program.
