Sentence examples for control rod position from inspiring English sources
Based on the validated model a robust nonlinear controller for controlling output power by manipulating control rod position has been developed and simulated.
These measurements include neutron density, coolant temperature and control rod position.
Several neutronics and thermo-hydraulics parameters are now registered, such as the operation power, the reactivity insertion in the core, the control rod position, the fuel and the water temperatures, and so on.
Parametric studies for stability have shown that the inlet loss coefficient, exposure, control rod position, and axial power shape are the most important parameters that might affect the accuracy of decay ratios for in-phase and out-of-phase modes of stability analysis.
Coupled neutronic/thermal-hydraulic analyses are defining the initial distribution of enrichment, control rod positions and the use of burnable poisons.
To validate the MCNP model, the simulated values of initial criticality with control rod positions, excess reactivity, shutdown margin and combined control rod worth are compared with the published work.
The relative error in criticality is 2.6% (with control rod positions 51.6% out of the core), 2.7% in excess reactivity, 6% in the shutdown margin and 3.3% for combined control rod worth has been observed.
Regarding the control rods position prediction, the RRP showed the results, which were closer to experiment than the uniform model.
In addition, the difference in control rods position between the RRP and uniform models also increases from 12 to 17 mm as increasing number of fuel columns from 19 to 30.
The experimental data are core parameters such as control rods position, coolant inlet temperature, power level and signal of ex-core neutron detectors taken from Bushehr nuclear power plant (BNPP) for each operation state.
The CRDA is a very localized event depending on the control rod insertion position and the fuel assemblies surrounding the control rod falling from the core.
