The volumetric heat production formula for spherical geometry is defined as q=(Σ*Φ*A*C)/V, where V represents the volume, A is the first-wall surface area in cm², C is the energy conversion factor (200 MeV x 1.602189 x 10-13 J), and Σ is the integral fission rate in the first fuel row (fission/neutron). To calculate volume (V) when the triso fraction rate is five percent of the total fuel rod volume, the correct approach is to use V*(5/100) in the calculation of q. This ensures that the core fraction rate is accurately accounted for in the heat production calculations.
