Helium/helium intermediate heat exchanger (URKO): 2nd semi-annual report 1987. Period August to December 1987

Automatic translation: By changing the pipe brackets, there is no need in the pipe field 48 tubes. The thermal calculation resulted in an increase in the straight pipe length by 2 x 400 mm. The bending of the Pipes in the deflection area with the load case ''Leave to stand hot'' conditional a larger outer diameter of the tube bundle. Through this the backflow jacket and the tank pressure jacket by 100 mm larger in diameter. The flow jackets were due to the Experience with the 10 MW test component from the holding jacket attached separately to the ring tube plate. Between inner and outer flow jacket became a rigid connection created.
