In 1989, the USNRC issued a new regulation, "Early Site Permits Standard Design Certifications and Combined Licenses for Nuclear Power Reactors" (lOCFR Part 52) [7] and is currently in the process of developing and issuing design certifications for two evolutionary ALWRs.

A concept of an evolutionary reactor is pursued with the joint French / German European Pressurized Water Reactor , EPR, a 1525 MW(e) plant with evolutionary steam generating system and innovative double-walled containment [20]. A three years basic design phase as a prerequisite for the beginning of the licensing procedure was finished in 1997. The characteristic feature is a core catcher to restrict a possible core melt to the power plant itself. The joint effort by Germany ind France, however, finds in both countries a situation where no further base load is required. The EPR, confirmed as a future standard in France, is projected to substitute decommissioned nuclear plants. 

Considering the development of an evolutionary reactor the European Pressurised Water Reactor (EPR) able to fiilfil the requirements of the 21st century, Framatome and Siemens founded their joint subsidiary, Nuclear Power International (NPI) in April 1989. 

Small and medium size reactor development has many incentives some are economic others are safety related. The motivation for these developments has included the need to enhance public acceptance of nuclear power. The simplification of designs should improve the transparency of their reactor safety. Another incentive to SMR development has been its suitability for the implementation of new design approaches. Innovative and evolutionary designs with novel feamres have been implemented in the SMR range. A passive safety approach has so far been the technology of small and medium reactors. SMRs have particular characteristics which can enable them to be economically viable in spite of losing the advantage of the economics of scale. 

The design studies performed in Russia confirm the possibility of a considerable evolutionary perfection for both marine-type reactors and power units on their basis to meet in full the specific requirements to future NPPs with small reactors. In particular, the possibility to exclude any operations for fresh fuel handling at the site for power units of up to 110 MWe was confirmed. The possibility to develop small reactor cores capable of operation without on-site refuelling over the period of 10-12 years was proved, which would allow to combine refuelling with the repair and maintenance of floating power unit at a specialized plant. 

Innovative SMR designs are under development for water cooled, gas cooled, liquid metal cooled and molten salt cooled reactor lines, as well as some non-conventional combinations thereof The targeted timelines of readiness for deployment vary between 2010 and 2030 the major concerns addressed by the innovation cover a broader spectrum of subject areas as compared to the operating and near term evolutionary NPPs, see Table 1. Such extended consideration is apparently due to the anticipated growth and geographical expansion of nuclear power. 

LWRs were developed 50 years ago. Their successful implementation was based in part on experiences with subcritical fossil-fuel fired power technologies at that time. The number of supercritical FPPs worldwide is larger than that of nuclear power plants. Considering the evolutionary history of boilers and the abundant experiences with supercritical FPP technologies, the supercritical pressure light water cooled reactor is the natural evolution of LWRs. 

This report provides the presented papers and summarizes the discussions at an IAEA Technical Committee Meeting (TCM) on Natural Circulation Data and Methods for Innovative Nuclear Power Plant Design. While the planned scope of the TCM involved all types of reactor designs (light water reactors, heavy water reactors, gas-cooled reactors and liquid metal-cooled reactors), the meeting participants and papers addressed only light water reactors (LWRs) and heavy water reactors (HWRs). Furthermore, the papers and discussion addressed both evolutionary and innovative water cooled reactors, as defined by the IAEA. ...
