METHOD OF COMPACTING RADIOACTIVE LONG-LENGTH MEMBERS OF ZIRCONIUM AND ZIRCONIUM ALLOY STRUCTURES Russian patent published in 2005 - IPC

Abstract RU 2244354 C1

FIELD: nuclear power engineering.

SUBSTANCE: compaction involves cutting members into fragments using electroerosive destruction of member wall by pulse spark-arch discharges emerging between member and electrode. In addition, high-temperature treatment in oxidizing medium, in particular vapor formed, is carried out. Cutting and heat treatment are accomplished in water.

EFFECT: simplified procedure and increased safety.
