3. Impact of Pu on reactor characteristics
3.1 Impact on thermal neutron reactors
As we saw earlier, the use of MOX in a thermal neutron reactor tends to increase the absorption rate in the thermal zone, leading to a lower heat flux. This is known as spectrum hardening.
The consequences are manifold .

This reduces the effectiveness of the control clusters and soluble boron used in PWRs to control excess reactivity at the start...
