Determination of plutonium in HANARO irradiated fuel by IDMS
- 1. Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)
Description
Two methods, IDMS (Isotope Dilution Mass Spectrometry) and controlled potential coulometry are compared by the determination of Pu for the NBL, CRM No.122, PuO2. The recovery of Pu was found to be 1.002176±0.000452 within the relative standard deviation of 0.045% (95% conf. level) although a small size of sample (0.9 μg-Pu) was used in IDMS. The recovery using controlled potential coulometry were obtained in the range of 0.9923∼0.9960. The analytical results of IDMS and controlled potential coulometry were good agreement within 0.6∼1%. Base on these experiment results, the plutonium in HANARO irradiated fuel rod that separated portion of top, middle, and bottom were determined. The measured values of Pu are 1.155 mg, 2,483 mg and 1.920 mg in one gram of sample(fuel+clad), respectively
