The advent of SMR (small modular reactor) technology is enabling a resurgence of nuclear power with its flexibility for versatile applications. This paper addresses emerging areas of nuclear power utilization and presents two examples of potential applications. The study proposes a conceptual design of SMR-propelled vessel to help clean the oceans laden with plastic wastes by capturing and recycling them onboard. Another example of nuclear power application is to complement the limitations inherent in renewable power plants that are being installed at an accelerated pace around the world. Some interesting and challenging thermal hydraulic issues associated with these emerging areas are addressed for future studies.
