    The main safety functions considered in the preliminary concept for the High Performance Light Water Reactor (HPLWR) have been evaluated by means of a comprehensive set of analyses, which have been performed using system and coupled codes. The investigated scenarios addressed a variety of initiating events, including anticipated transients as well as accidents. The simulations performed show that for each class of transients at least one of the computational tools used in this project is adequate for preliminary assessment of the safety concept of the HPLWR. The analyses have shown that the proposed systems can be expected to be capable to provide all the safety functions. The open issues that remain to be addressed in future projects are also discussed.
