Evolution of designs since the last IAEA status report on SMRs

Evolution of designs since the last IAEA status report on SMRs 

Five SMR designs presented at the meeting were previously addressed in the IAEA-TECDOC-881 Design and Development Status of Small and Medium Reactor Systems (1995) [1]. Table 2 illustrates the changes in their design and regulatory status over the period from 1995 to 2004. 

Though being based on a limited number of inputs, Table 2 points to a particular progress in the development status achieved by some SMR designs, such as CAREM, AHWR, KLT-40, SAKHA-92, and ABV. It could be mentioned that huge delays in the development of SMR projects, which are with no exception observed for all designs, may in some cases stimulate the designers to introduce particular modifications, for example, to focus on the reactors of different unit power (ABV, RUTA). 

Other SMR concepts and designs presented at the meeting were not addressed in the IAEA-TECDOC-881 [1], which points to a significant change in the scope of SMR projects over the past decade.
