Study on Entrapment: Splashing of Liquid UO sub 2 over Small Sodium Volumes

摘要

Three experiments were done in which each time more than 1 kg of liqid UO sub 2 was splashed over a plate in which different stainless steel cups full of sodium were contained. No indication of entrapment of sodium could be found. The pressure tests indicate up to 1,8 atm and they relax in some second time. These pressure diagrams have been satisfactorily analysed as indicating a sodium vapor formation. In the third experiment e.g. the quenching of 800 g UO sub 2 in 720 g of sodium in a closed volume of argon of 225 l will provide the requested maximum pressure. (Atomindex citation 10:492011)
