Abstract
4S (Super-Safe, Small and Simple) is a sodium cooled fast reactor with non-refueling core, aiming to play a local energy supplier. The core is very tall and has a dense arrangement of thick fuel pins in order to achieve a long life. Since previous thermal hydraulic data is limited to thin fuel pin bundles with larger pin-to-pin gap, we have conducted analytical and experimental studies focusing on the thermal hydraulics for such a unique fuel subassembly. The present paper addresses water tests with full bundle and partial bundle models.
