| Popis: | This paper presents an attempt to derive uncertainty values in the prediction of BWR and PWR transient scenarios. The small break LOCA counterpart tests performed in the BWR simulators Piper-one, Fist and Rosa-III, and natural circulation experiments performed in the PWR simulators Lobi, Spes and Lstf, constitute the basis of the activity. The application of Relap5/mod2 to the analyses of the above experiments, the evaluation of the comparison between predicted results and measured data, and the calculation of the BWR and PWR plants scenarios, were fundamental in achieving the proposed goal. The main result of the activity is constituted by the development of a methodology suitable for deriving uncertainty values of code calculations. The values reported for the uncertainty should be considered as the result of a demonstrative pilot application of the methodology. |
