3. 2nd NUCLEAR REGULATORY INFORMATION CONFERENCE
Introduction
The IAEA has up to now devoted a number of initiatives to support the development and deployment of SMRs;
It recognized their potential as options for enhancing the energy supply security both in expanding and embarking countries;
The driving forces in the development of such reactors are:
- meeting the need for flexible power generation;
- replacing ageing fossil fuel power plants;
- enhancing safety performance (inherent and passive);
- offering better economic affordability;
- suitability for non-electric or co-generation applications;
- offering options for remote regions off-grid;
- offering possibilities for synergy with other energy sources.

4. 2nd NUCLEAR REGULATORY INFORMATION CONFERENCE
Main Objectives
Modular reactors defined as advanced reactors that produce electric power up to 300 MWe;
The trend in the development has been towards design certification of small modular reactors;
Designed for sub-systems to be built in factories and shipped on skids to site;
Offers the opportunity to reduce lengthy construction times, increase quality and therefore reduce financing costs;
The projected timelines of readiness range from now to

Overview of SMR development status in 2016
11 countries are developing about 50 SMR designs with different time-scales and 4 units are either under construction or have a certified design.
