The Nuclear Alternative Project (NAP), a nonprofit group supporting the use of advanced reactors in Puerto Rico, has released the findings of a preliminary feasibility study undertaken to explore in detail the potential for these devices on the Caribbean island. The 288-page study, Preliminary Feasibility Study for Small Modular Reactors and Microreactors for Puerto Rico, was sponsored by the Department of Energy. The study concludes that small modular reactors and microreactors could be part of Puerto Rico’s energy portfolio and potentially supply a substantial part of a strong and diverse zero-emission energy mix.
