## Nuclear Shipping Event
Brazil held a nuclear energy event in Rio de Janeiro on Monday, September 9.
## Nuclear Ships Reduce Fuel Needs
Nuclear-powered ships use reactors to move turbines or electric propulsion systems without burning large fuel amounts.
## Lower Emissions and Longer Voyages
These ships cut greenhouse gas emissions and allow longer trips with fewer refueling stops.
## Contra-Almirante Humberto Ruivo
Contra-Almirante Humberto Ruivo, head of naval security, says nuclear ships last longer and need less refueling.

> São inúmeras vantagens, como, por exemplo, maior velocidade de trânsito, um combustível que dura muito mais tempo, portanto os navios não precisarão abastecer frequentemente ao estarem transportando mercadorias
## Regulation Needed for Nuclear Ships
Nuclear ships require safety certifications and global acceptance before widespread use.

> E é importante lembrar que para essa tecnologia ser viabilizada, ela precisa ser licenciada, ela tem que ser segura. A população mundial tem que aceitar esse tipo de meio. E aí então é necessário que existam normas com requisitos que precisam ser demonstrados comprovando a segurança dessas tecnologias, para que elas possam ser empregadas no mundo e aceitas universalmente, assim como os aviões andam de um país para outro, sendo aceitos em todos os aeroportos
## Key takeaway

Brazil's naval security agency says nuclear ships reduce fuel needs and allow longer voyages without refueling.
