1. Introduction

As one of the six reactor concepts selected in the Generation IV Technology Roadmap, the lead fast reactor (LFR) has become very attractive in recent years, and its development is pursued in several countries [1,2]. The attractiveness of the LFR is justified by the intrinsic characteristics of the system, which are able to completely satisfy the goals of the Generation IV International Forum (GIF). The system's enhanced safety is a particularly important characteristic, as safety is becoming one of the key criteria in the choice of a next-generation nuclear system. This paper briefly outlines the various on-going initiatives dedicated to the development of lead technology. The use of lead as a coolant permits a complete change of the design approach and provides several possibilities for innovation that will be briefly described here.

5. Conclusions

From the start of the Generation IV activities, it was evident that the LFR had a very strong potential to satisfy all the GIF goals. Due to previous experience and the expected corrosion problems of lead and LBE liquid coolants, most of the efforts of Generation IV were in the direction of fast reactors using sodium coolant. However, recent advancement has been made in terms of provisions and materials that are able to withstand flowing liquid lead corrosion. This fact, along with the obvious advantages offered by lead coolant in terms of safety, has provoked renewed interest from researchers and developers, as can be seen in the fast evolution of several initiatives around the world. The technological merits of the LFR and its compliancy with the goals of Generation IV are substantial prerequisites for finding an adequate level of financing to bring nuclear energy to a new level in the near future.
