• W2043295588 abstract "The stability of a self-pressurized natural circulation integral reactor is studied by means of a linear approach, taking the CAREM-25 reactor as reference. A thermohydraulic code has been improved for analysis of linear stability, great emphasis having been placed on the minimization of numerical diffusion and integration errors. A linearization method is implemented by means of numerical perturbations. The results are obtained within the frequency domain. The code is compared to a simpler analytical model, by contrasting stability maps obtained from both models for a test configuration, showing good agreement. In this type of reactor, oscillations are promoted by the two-phase regime in its long riser, and take place due to the counteraction between mass flow and buoyancy force. The stability of the system is strongly influenced by the steam-dome dynamics. Condensation in the steam zone, together with reactor power, determines the dynamical state of the system. The phase-lag introduced by the core dynamic regarding the riser timing, together with the sensitivity of the buoyancy force due to flow changes, determines the sustainability of the oscillation. A parametric study is carried out, gradually increasing the complexity of the model, to analyze the influence of different factors on the oscillation sustainability, concerning physical process and modeling approaches. The analysis includes the relative velocities between phases, the axial power profile along the core, the buoyancy force due to subcooled density changes, the flashing effect, the core dynamic and the pressure feedback due to self-pressurization. The steam-dome-pressure feedback is identified as a stabilizing effect, as long as it decreases the sensitivity of the buoyancy force." @default.
