Transient simulation, going from the critical configuration called H₁ to different supercritical states (H₂, H₃, H₄) by adjusting the water level in the tank. The results of the kinetic simulation in TRIPOLI-4 are compared with the solution of the point-kinetics equation, using the adjoint-weighted kinetics parameters. Results have been obtained both with the ENDF/B-VIII.0 (left) and the JEFF-3.3 (right) nuclear data library.
