Criticality of fuel-containing materials in the “Shelter” object [PDF]

open access: yesNuclear Physics and Atomic Energy
The article presents the results of the analysis of the validity of simplifications and assumptions accepted by researchers in the models of neutron-physical characteristics of fuel-containing materials (FCM) in the "Shelter" object (SO). The analysis and substantiation of the FCM nuclear safety will be one of the important issues during the SO ...

Dose and temperature distribution in spent fuel containing material [PDF]

open access: yesEPJ Nuclear Sciences & Technologies, 2016
Spent fuel containing material (SFCM) can arise during severe nuclear reactor accident by melting of a reactor core and surrounding material (corium) or during accident in spent fuel storage. It consists of nuclear fuel, fission products, activation products and materials from fuel cladding, concrete, etc.

On material and energy sources of formation of fuel-containing materials during Chernobyl NPP UNIT 4 accident [PDF]

open access: yesNuclear Physics and Atomic Energy, 2016
Results of detailed analysis of material substance of lava-like fuel-containing materials sources (FCM) and clusters with high uranium concentration were presented. Material and energy balance are aggregated in a process model for optimal composition of sacrificial materials and FCM. Quantitative estimate is given for spent nuclear fuel’ afterheat in a

Phase composition of brown ceramics of lava-like fuel-containing materials of the object “Shelter” ChNPP

open access: yesNuclear Physics and Atomic Energy, 2019
Using the X-ray diffraction method, the phase content of brown ceramics of lava-like fuel-containing materials of the “New Safe Confinement – Shelter Object” Complex was investigated. Their type was identified and crystalline phase composition was estimated. Characterization of the silicate glass phase was also carried out.
