...George-Rafael Domenikos; Emmanouil Rogdakis; Irene Koronaki In this work, the authors show an apparent connection in the behaviors of superfluid Helium in its two stable isotopes, where the lambda transition to superfluidity is seen to correspond to a theoretical Bose–Einstein condensation...

... plant design is driven by a high-temperature helium-cooled nuclear reactor coupled to a direct Brayton power cycle. The reference design reactor power is 600 MW t , with a primary system pressure of 7.0 MPa, and reactor inlet and outlet fluid temperatures of 540 ° C and 900 ° C , respectively...
