Effects of Waterlogged Fuel Rod Rupture on Adjacent Fuel Rods and Channel Box under RIA Conditions [PDF]
Journal of Nuclear Science and Technology, 1987 This paper describes the results of in-pile experiments and analyses to study the influence of waterlogged fuel rod rupture to the adjacent fuel rods and channel box under reactivity initiated accident (RIA) conditions. A single waterlogged fuel rod surrounded by intact fuel rods m a flow shroud was irradiated by a large neutron pulse in the Nuclear ...

Criticality safety of fuel assemblies with missing fuel rods
Annals of Nuclear EnergyInternational audience ; The present work is concerned with the problem of determining the reactivity of an assembly from which an unknown number of fuel pins are removed at random locations. Because it is usually designed to be under-moderated, the reactivity of an incomplete assembly will pass by an optimum when the number and position of the missing

Friction and wear of elements of nuclear reactors [PDF]
E3S Web of Conferences, 2023 Fuel elements (fuel rods) and spacer grids are the main elements of the fuel assembly of a nuclear reactor. Friction forces affect the strength of the fuel assembly at all stages of its life cycle.
