N2 - An increasing interest on the development of highly accurate methodologies in reactor physics has been observed during the last years. The McSAFE high-fidelity project has the objective of moving multiphysics schemes based on Monte Carlo (MC) neutronic calculations to become valuable tools for industry-like applications for LWRs for steady-state, burnup and transient calculations. This work deals with the transient calculation capabilities, developed here through the coupling between the Serpent 2 MC code and the subchannel code SUBCHANFLOW. This is done through a new versatile internal (master-slave) coupling, recently rewritten from scratch to include both codes inherent capabilities. To verify the implementation, a series of RIA-type transients scenarios are proposed and solved for a PWR minicore, considering a pin-by-pin level coupling. Global and detailed results are obtained and analyzed, verifying the consistency and showing the capabilities of the tool. Finally a raw estimation of resources requirements is presented and briefly discussed.
