Main model parameters uncertainties (2/2) following a uniform law.

Uncertainty around the modeled variables Inf limit(% of the nominal value added) Sup Limit(% of the nominal value subtracted)
Thermal heat exchange in turbulent forced flow in CATHARE2 (Shupinsky correlation) −15 15
Thermal heat exchange in turbulent forced flow used at the primary side of the IHX (Borinshanki-Firsova correlation) −30 30
Wall/fluid Thermal heat exchange in single-phase flow(Seban-Shimazaki correlation) −6 6
Regular head losses: 3 various correlations depending on Reynolds number −50* 50
Head loss on the primary pumps at off state −20 20

*This high uncertainty range is governed by the maximal uncertainty of the 3 correlations (Blasius, Hagen-Poiseuille and Rehme correlations).
