【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、アルカリ金属、例えば金属ナトリウム冷却高
速増殖炉、あるいは金属ナトリウムを使用する施設から
発生する金属ナトリウム廃棄物の処理装置に関する。TECHNICAL FIELD The present invention relates to an apparatus for treating metallic sodium waste generated from an alkali metal, for example, metallic sodium cooled fast breeder reactor or a facility using metallic sodium.
従来、金属ナトリウム廃棄物の処理方法として、 （１）水蒸気あるいは湿り窒素ガス等と接触させて水酸
化ナトリウムとする方法 （２）アルコールと反応させてナトリウムアルコラート
とする方法 等がある。Conventionally, as a method of treating metallic sodium waste, there are (1) a method of contacting with steam or wet nitrogen gas to form sodium hydroxide, and (2) a method of reacting with alcohol to form sodium alcoholate.
金属ナトリウムは活性な金属であり、その廃棄物処理は
やつかいである。特に長期間放置されていた等により、
金属ナトリウム表面がナトリウム化合物（主としてNaO
H）でぶ厚くおおわれている場合には、前記の処理方法
（１）および（２）ではナトリウム化合物層が速やかに

えば水の中に入れて溶解させる等）で金属ナトリウムが
露出して爆発等の事故に至る恐れがある。Sodium metal is an active metal and its waste disposal is awkward. Especially because it was left for a long time,
The surface of sodium metal is a sodium compound (mainly NaO
When it is covered with H), the sodium compound layer cannot be removed promptly by the above-mentioned treatment methods (1) and (2). That is, NaOH on the surface of sodium metal acts as a barrier to slow the reaction rate. For this reason, there is a possibility that an erroneous judgment that there is no metallic sodium is made and metallic sodium is exposed in the next treatment step (for example, by putting it in water to dissolve it), leading to an accident such as an explosion.
また、前記の処理方法（１）では、生成したNaOHが強ア
ルカリであり、取扱いに注意を要する。Further, in the above-mentioned treatment method (1), the generated NaOH is a strong alkali, and thus care must be taken in handling.
更に、前記の処理方法（２）では、可燃物であるアルコ
ールを使用すること、コスト的にも高価となること等の
欠点を有し、大量処理には不向きである。Furthermore, the treatment method (2) has drawbacks such as the use of alcohol which is a combustible substance and the high cost, and is not suitable for large-scale treatment.
そこで本発明は大量に、安全に、機器等の表面に付着し
たナトリウムその他のアルカリ金属を処理することので
きる装置を提案するものである。Therefore, the present invention proposes an apparatus capable of safely treating a large amount and safely of sodium and other alkali metals attached to the surface of a device or the like.

り容易に処理することができる。When treating the alkali metal waste with the apparatus of the present invention, by bringing carbon dioxide into contact with the alkali metal waste covered with thick alkali hydroxide, the alkali hydroxide layer on the surface becomes alkali carbonate and expands. Will come off. As a result, most of the surface alkali hydroxide layer which has been a barrier can be removed, and the alkali metal and the slightly remaining alkali hydroxide can be easily treated by the conventional method.

金属ナトリウムが水分と反応し、 2Na＋H2O→2NaOH＋H2 （１） この水酸化ナトリウムが炭酸ガスと反応し、 2NaOH＋CO2→Na2CO3＋H2O （２） 水素は水分に再結合される。Metallic sodium reacts with water, 2Na + H 2 O → 2NaOH + H 2 (1) This sodium hydroxide reacts with carbon dioxide, 2NaOH + CO 2 → Na 2 CO 3 + H 2 O (2) Hydrogen is recombined with water.
H2＋1/202→H2O （３） 総合的な化学反応は 2Na＋CO2＋1/202→Na2CO3 （４） となる。H 2 +1/20 2 → H 2 O (3) The overall chemical reaction is 2Na + CO 2 +1/20 2 → Na 2 CO 3 (4).
