In this paper we have analyzed accounting spent nuclear fuel (SNF) burnup of VVER-1000 and RBMK-1000 only with actinides. The following characteristics were analyzed: initial fuel enrichment, burnup fraction, axial burnup profile in the fuel assembly (FA) and fuel weight. As the results show, in the first 400 hours after stopping the reactor, there is an increase in the effective neutron multiplication factor (keff) due to beta decay of 239Np into 239Pu. Further, from 5 to 50 years, decrease in keff due to beta decay of 241Pu into 241Am. In the future there is a slight change in criticality of the system. Accounting nuclear fuel burnup in the justification of nuclear safety of SNF storages will provide an opportunity to increase the volume of loaded fuel and thus significantly reduce technology costs of handling of SNF.

Key Features

The paper presents basic results of development of a criticality accident alarm system to ensure safe retrieval of the spent nuclear fuel from the Lepse Floating Maintenance Base. The key features and engineering aspects of the system design are described. Locations of criticality detector units and selected alarm level settings are justified, hazardous area boundaries were identified, and parameters to identify inadequately protected zones were calculated. The SRKS-01D criticality accident alarm system by SPC “Doza” was selected as base equipment. The system was commissioned in 2019 and has been successfully operated for more than 6 months.
