TRACT COMPUTER CODE APPLICATION IN THE ASSESSMENT OF SNF AND RW CLASS 1 RADIONUCLIDE COMPOSITIONS AND RADIATION CHARACTERISTICS

JOURNAL: 2020, 14, p. 99-111

AUTHOR: A.I. Blokhin, P.A. Blokhin, S.T. Kazieva

ANNOTATION:

The article presents the results of computational studies addressing radionuclide compositions and radiation characteristics of spent nuclear fuel from WWER-440 and BN-600 reactor units performed using new computer code TRACT. These studies are performed to acquire basic information enabling further forecasts of RW Class 1 characteristics generated from the reprocessing of these fuel types. The calculations allowed to identify the characteristics of WWER-440 and BN-600 SNF considering various irradiation and storage conditions, including different burnup levels and pre-reprocessing cooling times. Such data will enable further evaluation of possible ranges describing the characteristics of RW Class 1.

Keywords: computer code, nuclide kinetics, spent nuclear fuel, radiation characteristics, energy release, pressurized water power reactor, sodium-cooled fast neutron reactor, radioactive waste, aluminum-phosphate glass.
