Após
ingressar na seleta lista de países com um porta aviões, o Brasil vai integrar
um grupo ainda mais restrito, o das nações com um submarino nuclear.





A previsão é que a embarcação esteja pronta para
os primeiros testes de mar em 2023. Atualmente, o projeto passa pelas fases de
construção do protótipo do reator nuclear e produção do combustível, que devem
ser concluídas em dois anos.Será a primeira vez que o Brasil construirá
integralmente um reator nuclear. Os principais equipamentos para sua montagem
foram adquiridos ao longo dos anos, já que a ideia de ter um submarino com esse
tipo de propulsão surgiu no País há mais de duas décadas.O primeiro submarino
nuclear do mundo foi o Nautilus, fabricado pelos Estados Unidos em 1954. Quase
60 anos depois ,apenas cinco países contam com esse tipo de embarcação&nbsp; Rússia, China, Inglaterra e França, além dos Estados Unidos.






&nbsp;
A principal diferença entre os submarinos convencionais e os de propulsão
nuclear está no motor. Enquanto o primeiro se movimenta graças a um motor a
diesel, o segundo utiliza um reator nuclear.
O submarino brasileiro não usará armamento nuclear. Isso se deve,
principalmente, ao Tratado de Não- Proliferação Nuclear (TNP), assinado pelo
País em 1968 e que impede a uso dessas armas pela nação.Os engenheiros estão
trabalhandono centro de engenharia da DCNS em Lorient, oeste da França , no
projeto do submarino nuclear brasileiro, e que retornam ao Brasil no meio do
ano.
