Another achievement for Brazil’s national sovereignty and for the technological advancement: The start of the assembly of the Nuclear Propulsion Prototype Reactor of the Submarine Development Program (PROSUB), was celebrated this Wednesday (October 21) at the Aramar Experimental Center, in Iperó, São Paulo.
The Minister of Defense, Fernando Azevedo, accompanied the President of the Republic, Jair Bolsonaro, during the ceremony, which also counted on the presence of the Navy Commander, Admiral Ilques Barbosa.
The ceremony, held at the Nucleo-electric Generation Laboratory (LABGENE) complex, marks the beginning of an important stage of PROSUB, which is part of the Navy Nuclear Program (PNM). This is because the assembly of the reactor will, in the future, be replicated in the construction of the first Brazilian submarine with nuclear propulsion, the «Álvaro Alberto».
In the next phases of the program, the reactor, as well as the turbine generators, the electric motor and other systems similar to those of a nuclear-powered submarine, will be tested in a controlled manner at LABGENE. The purpose is to validate the operation of the reactor and the various electromechanical systems integrated with it, prior to installation on the submarine.
After the tests are finished, a similar reactor will be installed in the submarine Álvaro Alberto, projected in the Naval Complex of Itaguaí, in Rio de Janeiro. It is in Itaguaí that the four submarines with diesel-electric propulsion are being developed, also included in the PROSUB program: the Riachuelo (S-40), already launched, the Humaitá (S-41), the Tonelero (S-42) and Angostura (S-43).
PNM and PROSUB are part of Brazilian Defense Programs and foster the country’s capacity to design, build, operate and maintain nuclear powered submarines. With this, Brazil will join the list of five countries with these competencies. They are: United States, United Kingdom, France and China.
Submarines are essential, not only for defense policy, but also to stimulate national development and guarantee naval sovereignty.
The Minister of Defense pointed out that «PROSUB is extremely important for Brazil, as it adds operational capacity to the Navy and adds very large deterrent power to our Armed Forces and to the defense of our country».
