Optimization parameters for determination electrodeposition process isotopes ²³⁵U and ²³⁹Pu in PEB U₃Si₂/Al post irradiated

Has done electrodeposition process parameter optimization isotope ²³⁵U in the standard solution U₃O₈ and isotopes ²³⁵U and ²³⁹Pu in fuel element plate (PEB) U₃Si₂/Al post-irradiation. Electrodeposition process is carried out in an electrolyte medium 1 M ammonium sulphate pH 3.5 and heavy isotopes ²³⁵U and ²³⁹Pu analyzed by alpha spectrometry methods. The research objective is to obtain optimum parameters electrodeposition process with current variation, timing and volume of feed as well as determine the content of heavy isotopes ²³⁵U and ²³⁹Pu from the result of condensation of PEB U₃Si₂/Al post-irradiation. Electrodeposition process carried out by the current variation of 1.2 and 2.0 ampere with a variation of 1.5; 2.0; 2.5 and 3.0 hours as well as the volume of feed 300; 500; 700 mL for the standard U₃O₈, but the volume of feed for PEB solution U₃Si₂/Al post-irradiation ranging from 50, 100, 150, 200, 250, 300 and 500 mL. The results showed that the optimum conditions for the electro deposition process is obtained with a current of 1.2 amperes with processing time for 2 hours and the amount of feed volume of 300 mL for the standard U₃O₈. Heavy deposition electrodeposition hashish obtained isotope ²³⁵U of 2,314 g with the percentage of precipitation (recovery) of 99.91 %. Heavy sediment ²³⁵U isotope in solution PEB U₃Si₂/Al postirradiation on the feed volume of 50 to 500 mL of the results obtained with a recovery of 91.80 %, by weight where as precipitate obtained isotope ²³⁹Pu in succession 9.9 x10^-05; 2.6x10^-04; 8x10^-04; 5.6x10^-04; 6.5x10^-04; 1.0x10^-03 and 1.4x10^-03 g. From the results, it otherwise that good enough electrodeposition method used to determine the particular alpha emitting isotopes ²³⁵U and ²³⁹Pu isotope in solution PEB U₃Si₂/Al post-irradiation.
