Dynamic probabilistic risk assessment (DPRA) methodologies couple system simulator codes (e.g., RELAP, MELCOR) with simulation controller codes (e.g., RAVEN, ADAPT). Whereas system simulator codes model system dynamics deterministically, simulation controller codes introduce both deterministic (e.g., system control logic, operating procedures) and stochastic (e.g., component failures, parameter...

Recent R&D activities in nuclear fusion have identified the DEMO reactor as ITER successor, aiming at demonstrating technical feasibility of plants, along with their commercial exploitation. However, pulsed operation machine causes an “unconventional” system, posing unique challenges to functional steam generator, for which it is necessary define and qualify a reference configuration DEMO. ...
