Method and apparatus for processing hollow bodies filled with metallic sodium

摘要

A method for safely cutting hollow bodies filled with metallic Na for disposal comprises the steps of cutting the hollow bodies with plasma jet so as to oxidize metallic Na while conveying said hollow bodies in a hermetically sealed housing, throwing the cut hollow bodies into a neutralizing aqueous solution tank, then taking out said cut hollow bodies from the tank, collecting a fume produced while cutting the hollow bodies, spraying water over the fume and recovering the fume. An apparatus for carrying out the above method is also disclosed.
