nobody can solve my Nuclear Reactor Physics Question? please help me!

In the centre of the core of a 1000 MWe BWR, the observed fission rate is 1.7×10¹² cm^-3 s^-1 and the observed temperature of the fuel is 800 ^oC. What will be the fission rate at the same location if the temperature is raised to 1000 ^oC? (Hint, Σf is a non- 1/v cross-section.)

Rx(r,E,t) = Σ_x(r,E) v n(r,E,t) i don't know it is the right way or not. for non-1/v cross section:
R_a=g_a(T)Σ_a(E₀)Φ₀

and i don't know how can i use temperature for this problem?

You should show some of your own work before expecting help here. What equations might be relevant to the solution? What have you tried so far that hasn't worked?

Consider g_a(T).

Assume the flux and energy spectrum are the same. Then consider g_a(800 °C) and g_a(1000 °C).
