Qualification of TRACE V5.0 Code against Fast Cooldown Transient in the PKL-III Integral Test Facility by Eugenio Coscarelli, Alessandro Del Nevo, Francesco D'Auria

“…This leads to a strong asymmetry caused by an increase of the heat transfer from the primary to the secondary side that induces a fast cooldown transient on the primary side-affected loop. The asymmetric overcooling effect requires an assessment of the reactor pressure vessel integrity considering PTS (pressurized thermal shock) and an assessment of potential recriticality following entrainment of colder water into the core area. …”

Stabilization and Synchronization of Uncertain Zhang System by Means of Robust Adaptive Control by J. Humberto Pérez-Cruz

“…However, in the presence of unmodeled dynamics and/or disturbance, this approach is not effective anymore due to the drift of the parameter estimations, which eventually causes the instability of the closed-loop system. In this paper, a robustifying term, which consists of a saturation function, is used to avoid this problem. …”
