... missions is increasing. Almost all deformation of the fuel pellets due to thermal stress at high the existing space nuclear reactors have adopted the design of temperatures and the reactivity changes caused by the gas-cooled fast reactor, and the temperature feedback effect of deformation are analyzed...

... the mechanism of the large temperature fluctuations at the elbow of the branch pipe and evaluate thermal stress that lead to the fatigue crack. A series of mock-up experiments were conducted with vertical straight pipe (the straight-pipe) and a vertical pipe with an elbow connected to a horizontal pipe...
