Resumo
The pressure on reduction of gas emissions is going to raise the price of fossil fuels and an alternative to
fossil fuels is nuclear energy. Naval reactors have some differences from stationary PWR because they
have limitations on volume and weight, requiring compact solutions. On the other hand, a source of
problems in naval reactors across history is the steam generation function. In order to reduce nuclear
containment footprint, it is desirable to employ integral designs, which, however, poses complications
and design constraints for recirculation type steam generators, being interesting to employ once through
steam generators, whose historic at Babcock & Wilcox is better than recirculation steam generators. Plate
and shell heat exchangers are a mature technology made available by many suppliers which allows heat
exchange at high temperature and pressure. This work investigates the feasibility of the use of an array
of welded plate heat exchangers of a material approved by ASME for pressure barrier (Ti-3Al-2.5V) in a
hypothetical naval reactor. It was found it is feasible from thermal-hydraulic point of view and presents
advantages over other steam generator designs.
