I want to do coupled neutronic thermal-hydraulic analysis using COBRA and PANTHER.

From PANTHER, we can get Axial form factor (AFF) and Radial form factor (RFF) in each axial layer and radial nodes, respectively for whole-core calculations. In COBRA, we have to put linear power in the each core axial layer as input. An example is given below:

0.12 %layer height

5.6774E+03 %Linear Power at height = 0.12 m

0.36

1.6050E+04

0.61

2.3648E+04

0.85

2.7157E+04

1.09

2.5970E+04

1.33

2.0293E+04

1.58

1.1107E+04

1.82

5.6774E+03

From PANTHER AFF and RFF values, I want to calculate linear power in each layer of the core for giving input to COBRA.

Can you please check whether my calculation procedure is correct?

Suppose, my core has 10 axial layers.

Core height is 1.82 m.

Average core linear power is 11.3 KW/m

Suppose, in axial layer 1 at 0.12 m core height

Axial form factor (AFF) is 1.4

Radial form factor (RFF) is 1.6

Can I say that average linear power in axial layer 1: 11.3*1.4*1.6= 25.312 KW/m?

Can you please correct me if it is not correct with an example calculation?

Thanks in Advance!!
