Core Design Improvement for Higher Power Density

3 Core Design Improvement for Higher Power Density 

The total power can be described using the average linear heat rate q.  

Substituting the above two equations, the power density is described as (7.26). 

3 Example of Improved Core vfith Higher Power Density 

In the control systems of the Super LWR designed in Chap. 4, the main steam temperature is simply controlled by the feedwater pumps. Since the moderator in the large water rods mitigates the change in the coolant temperature in the Super LWR, the change in the main steam temperature is not very large (within 8°C). The
