Abstract
يتعلق الاختراع الحالي بمجال التكنولوجيا الكيميائية النووية، وبخاصة التكنولوجيات الكيميائية الإشعاعية عند مراحل مختلفة من دورة الوقود النووي، مثل إنتاج المواد النووية المنقاة (يورانيوم، زركونيوم) أو إعادة معالجة الوقود النووي المستنفد من محطات الطاقة النووية، والتي فيها يتم استخدام عمليات الاستخلاص وإجراءات تنقية المواد النووية. يتكون جوهر الطريقة الحالية، والتي تتضمن التحلل الجزئي لحمض النيتريك أثناء التبخير المستمر في حين أنه يتم تغذية عامل اختزال في الجزء السفلي من المبخر الذي له محلول نواتج سفلية يتم تدويرها، من أن العملية تُجرى بحيث يتم الاحتفاظ بالمحلول في الجزء السفلي من المبخر أكثر من ساعتين مع إضافة محلول مائي من الفورمالدهيد وحمض الفورميك (المٌشار إليه هنا فيما يلي andquot;الخليطandquot;) أو محلول من حمض الفورميك بعد أن تكون قد بدأت العملية باستخدام الخليط. ويمكن ذلك من اختيار نظام والذي فيه، أثناء تبخير رافينات نموذجية عالية النشاط تحت ظروف مستوى تركيز عال معطى (حجم محدد من محلول النواتج السفلية الذي لا يزيد عن 0.4 م3/طن من النفايات النشطة إشعاعيا)، فإنه لا يترسب نيترات الباريوم ولا ينطلق أكسيد النيتروز. بالإضافة إلى ذلك، يتم زيادة الآمن من الاشتعال والانفجار في العملية نتيجة لخفض كبير (يصل إلى عشر أضعاف) تركيز الفورمالدهيد في عامل الاختزال، وإمكانية استمرار العملية في ظل غياب كامل للفورمالدهيد، مستخدما حمض الفورميك.
