SU NPP Core Reload

In May, NFC STE specialists participated in SU NPP Unit 3 core reloading operations (unloading/loading) during 2023 outage. NFC STE specialists monitored core reload operations step by step according to recommended core reload sequences, specifically, unloading forces and velocity during FA unloading from the fresh fuel containers and fuel storage pool, as well as FA loading forces and velocity and impact (force) in the bottom support tube. Besides, structural integrity of FAs and their design position were monitored, as well as abnormal corrosion effects.
SU NPP Unit 3 core reloading was performed successfully without any unexpected complications and issues.
