A second project regards the CRP focused on benchmark analysis of one of the unprotected passive safety demonstration tests performed at the Fast Flux Test Facility (FFTF), the Loss of Flow Without Scram (LOFWOS) Test #13, started in 2018. In the framework of this project, the NINE Validation ProcessвЂ“ developed in the framework of NEMM (NINE Evaluation Model Methodology) вЂ“ has been proposed and adopted by most of the organizations to support the interpretation of the results calculated by the CRP participants and the understanding of the reasons for differences between the participantsвЂ™ simulation results and the experimental data. The first CRP was focused on the benchmark analysis of Experimental Breeder Reactor II (EBR-II) Shutdown Heat Removal Test (SHRT-17), protected loss-of-flow transient, which ended in the 2017 with the publication of the IAEA-TECDOC-1819. Within this framework, NINE is very actively participating in various Coordinated Research Projects (CRPs) organized by the IAEA, aimed at improving Member StatesвЂ™ fast reactor analytical simulation capabilities and international qualification through code-to-code comparison, as well as experimental validation on mock-up experiment results of codes currently employed in the field of fast reactors. In addition to current fast reactors construction projects, several countries are engaged in intense R&D and innovation programs for the development of innovative, or Generation IV, fast reactor concepts.

Their closed fuel cycle can support long-term nuclear power development as part of the worldвЂ™s future energy mix and decrease the burden of nuclear waste. Global interest in fast reactors has been growing since their inception in 1960 because they can provide efficient, safe, and sustainable energy.
