A comparison of bounding approach with isotopic correction factors and Monte Carlo sampling in burnup credit method [PDF]

open access: yesEPJ Web of Conferences, 2021
One of the methodologies used in criticality safety analysis is burnup credit method, which allows considering fuel burnup in models with spent fuel. This removes excessive conservatism from the analysis, but it also brings new uncertainties originating ...

Steam turbine flow path drainage system under different operating conditions [PDF]

open access: yesMATEC Web of Conferences, 2022
One of the important elements of anti-erosion protection of the steam turbine last blades is the use of hollow stator blades. There are grooves on the blade surface that lead the steam mixture inside the blades. This mixture is blown to the diffuser area.
