Power Release Estimation inside of a Fuel Pin Neighbouring a WWER-440 Control Rod

Popis výsledku v původním jazyce

This work presents an estimation of the control rod (CR) influence in the WWER-440 core on the power release inside of an investigated fuel pin (FP) neighbouring CR that can have some consequences, for example FP / fuel assembly bowing. For this purposedetailed axial power distribution measurements were performed in a WWER-440 type core on the light water, zero-power reactor LR-0 in selected FPs near to CR model. Results of above measurements were used for estimation of the: 1.Axial power distributioninside of the investigated FP in both opposite positions on its pellets surface that are situated to- and outwards CR and corresponding gradient of the (r , z) - power distribution in above opposite positions and 2.Azimuthal power distributions on pelletsurface of the investigated FP in horizontal planes at selected axial coordinates. Obtained information can be used for code validation and subsequently for FP failure occurrence investigation.
