PNP Prototype Plant Nuclear Process Heat. Semi-annual report 2nd half 1986. Development of large metallic components for the circuits of Prototype plant for nuclear process heat (PNP). V class 2

Automatic translation: After completion of the experiments and transport to Company Balcke-Dürr / Neubeckum became the 10 MW-URKO- Test heat exchanger so far disassembled that a Assessment of the bundle pipes, pipe supports, Coats and insulation could be made. The interim examination showed the following Picture: - All components and systems of the heat exchanger have the loads in the scheduled KVK test operation survived very well. In particular, the load transfer system, the hot collector, the U-tube deflections and the sliding points behave as expected. - The bundle pipes, pipe supports and jackets show no visible damage or Deformations. The pipes are in the Brackets move freely and the coating makes a visually flawless one Impression. Only in the deflection area (T <650 ° C) shows the pipe coating a pustular surface (also outside the friction path).
