الملخص EN
CIPS is a shift in the axial power towards the bottom half of the core, also known as axial offset anomaly (AOA), which results from the deposited of corrosion products during an operation.
The main reason of CIPS is the solute particles especially boron compounds concentrated inside the porous deposit.
The impact of CIPS is that the axial power distribution control may be more difficult and the shutdown margin can be decreased simultaneously.
Besides, it also requires estimated critical condition (ECC) calculations to account for the effects of AOA.
In this article, thermal-hydraulic subchannel code and boron deposit model have been combined to analyze the CIPS risk.
The neutronics codes deal with the generation of homogenized neutron cross section as well as the calculation of local power factor.
A simple rod assembly is analyzed with this combined method and simulation results are presented.
Simulation results provide the boron hideout amount inside crud deposits and power shapes.
The obtained results clearly show the power shape suppression in regions where crud deposits exist, which is a clear indication of CIPS phenomenon.
And the CIPS effects on CHF have also been investigated.
Result shows a margin of DNBR decrease in the crud case.
