ccurate predictive modelling of tokamak core turbulent transport is a vital component of in- tegrated tokamak simulation. The contribution of Electron Temperature Gradient (ETG) driven turbulence to electron heat transport in various operational regimes is an open question with extensive recent investigations [1], [2]. This paper focuses on validation of striking recent pre- dictions [3] of anti-GyroBohm isotope scaling of core transport, mediated by ETG turbulence.
