Neutronic safety and transient analyses for potential LEU conversion of the IR-8 research reactor.
Kinetic parameters, isothermal reactivity feedback coefficients and three transients for the IR-8 research reactor cores loaded with either HEU(90%), HEU(36%), or LEU (19.75%) fuel assemblies (FA)
MCU-PTR program for high-precision calculations of pool and tank type research reactors
The MCU-PTR program with a MDBPTR50 database has been developed to perform high-precision mathematical modeling of nuclear reactors and to calculate their neutron-physical characteristics.
Water velocity determination in the gaps of irt-3M, -4M fuel assemblies
Experiments on measuring the water velocity in the gaps between the fuel elements of an IRT-3M eight-tube fuel assembly with 90% fuel enrichment, used in pool and tank research reactors, are
Assessing the risk of welding defects
A method is proposed for determining the equivalent crack length in assessing internal welding defects in terms of the crack resistance of the material.
Optimization of FA Reloading in the IR-8 Reactor
The possibility of increasing 235U burnup in IRT-3M FA to 68% is examined for the example of equilibrium operating cycles of IR-8 and optimization of fuel reloading in the core is proposed. This
