Application of Probabilistic Leak-Before-Break for WWER-1000 Unit
Procedia Structural Integrity, 2019 Abstract In this paper a probabilistic Leak-Before-Break analysis for WWER-1000 unit was performed based on the Failure Assessment Diagram (FAD), treating strength and crack morphology parameters as stochastic values. In order to perform probabilistic calculations Critical temperature of brittleness and Yield (Ultimate) Stress, were fitted by normal ...

Development of a Neutronic Model of the WWER-1000 Reactor Facility Core
Eurasian Journal of Physics and Functional MaterialsA neutronic model of the WWER-1000 reactor has been developed. The reactor block of the B-320 series, which is the most common among NPPs with the WWER type reactors, was selected for the modeling. The modeling was performed using the MCNP6 software.
