4 Small and Modular Reactor (SMR) Market analysis High power nuclear energy production units usually need a high initial investment because they are unique and built on the place where they will produce energy. Small power units like the SMR can be built in modules in a production unit, that make them more competitive. SMR market is made of : Small grids in fast developing countries ; Non interconnected grids in large countries. Market size is estimated to hundreds of SMR over the next 20 years. 4 08/11/2013 PECC Victoria (CA) DCNS - SA all rights reserved / tous droits réservés 4
