Generation of unstable whistler mode is investigated in the presence of kinetic Alfven wave turbulence (KAW) field in a burning plasma. KAW turbulence is supported by plasma inhomogeneity in a burning plasma. The propagation of this low frequency KAW in inhomogeneous magnetized plasma is expected to play a significant role in heating energetic particles such as deuterium and tritium and the exchange of energy among waves to develop instability in fusion reactors. Whistler mode in a burning plasma may be amplified when the accelerated energetic particles transfer their energy to whistler mode nonlinearly through a modulated field. Considering a Maxwellian model of ion distribution function for inhomogeneous plasma with the involvement of a uniform force 
, we have evaluated fluctuating parts of the distribution function due to KAW turbulence using the Vlasov equation. We have also obtained nonlinear fluctuating parts of the ion distribution function due to modulated waves as well as nonlinear whistler mode. We have estimated the growth rate of the whistler mode using a nonlinear dispersion relation for the whistler mode.
