Progress in Nuclear Energy

The control rod speed design (CRSD) for core power control has been designed with the actual control rod drive mechanism (CRDM) model by considering the different type of saturations (hard saturation, soft saturation and sigmoid saturation), changes in the maximum control rod speed limiter and reactivity worth curve (experimental data) to predict the best response reactivity insertion rate for operating TRIGA research reactor. The new CRSD (nCRSD) model has been integrated with existing PI-type power controller to study the effects control performance (including small settling time, smoothness control surface during transient, small chattering error during steady-state and actuation signal for CRDM) of the proposed model. The effectiveness of the proposed method is tested by numerical simulations (Matlab/Simulink) and verified with experimental data from real plant by comparing the results with the conventional CRSD (cCRSD based on hard saturation and slow control rod speed).

This data includes the RAPID whole core (BEAVRS benchmark and small core model) transport calculation results with different collapsing options, tolerances of power iterations and precision in floating numbers. It also includes a estimate of the iterative error compared to the real one. Finally, RAPID with all acceleration and numerical techniques are applied on BEAVRS benchmark and compared to Serpent 2 Monte Carlo reference calculation.

The file has the data considered for decommissioning cost estimation of the case study site.
