| 요약 | In order to meet the worldwide demands on sustainable energy, new generation of nuclear reactor systems has been proposed to continue the benefit of nuclear power for electricity production. Sodium-cooled fast reactor (SFR) is one of the most pr |
| 요약 | The objective of this doctoral work is to develop a perturbation theory method for accurate and efficient evaluation of the feedback reactivity induced by SFR core deformation. The pre-calculated assembly bowing reactivity coefficient could be a |
| 요약 | The major challenge in using perturbation theory method to calculate the assembly bowing reactivity worth is the evaluation of the bi-linearly weighted reaction rate integral for a perturbed geometry. Direct adoption of the conventional perturba |
| 요약 | The key practice of the proposed perturbation theory method is to convert the problem of calculating material property perturbation to the problem of evaluating the difference of the fluxes to which materials are exposed at original and perturbe |
| 요약 | We developed a computer code named RAINBOW (ReActivity INduced by assembly BOWing) applying the proposed perturbation theory method. RAINBOW reads forward and adjoint fluxes from VARIANT and PROTEUS-SN solutions and reconstructs the heterogeneou |
| 요약 | The verification of the RAINBOW code was performed by comparing the perturbation results with the direct subtractions between eigenvalues of both unperturbed and perturbed cases. The reference eigenvalues were calculated by both MCNP6 Monte Carl |
