Laser-fluorescence monitoring of {sup 129}I in industrial reprocessing of nuclear fuel

Journal Article · · Radiochemistry
OSTI ID:28620

A laser-fluorescence system is developed that uses a He-Ne (633 nm) laser for continuous monitoring of {sup 129}I during HNO{sub 3} dissolution of irradiated nuclear fuel. Tests at Khlopin Radium Institute indicated that the sensitivity of the {sup 129}I detection (at worst 8{center_dot}10{sup {minus}5} g/m{sup 3}) ensures reliable monitoring of this isotope both directly in the working gas during industrial reprocessing of irradiated nuclear fuel and following gas-purification systems at radiochemical plants.
