PNP Prototype Plant Nuclear Process Heat. Half-yearly report 1st half 1989 Development of large metallic components for the circuits of Prototype plant for nuclear process heat (PNP). V-class 2.1

Automatic translation: The evaluation and documentation of the experiments on the 10 MWURKO Test heat exchanger in the KVK has been completed. The corresponding report is available [Interatom- Report 52.07088.4]. All in all, that despite the test-specific damage in the deflection area ofthe heat exchanger, the apparatus as a whole the Has provided proof of functionality. The thermal and thermodynamic design was confirmed by the test. The planning and development work for the 170 MW URKO heat exchanger were continued. The present Drawings and parts lists were checked and discussed and, if necessary, changed slightly. Particular attention was paid to the requirements Manufacturing, assembly and transportation as well as the requirements of basic security. During the transport it was found that especially the bundle with its weight of 285 t is likely to be too heavy for road transport and therefore a rail or waterway must be available. Otherwise it could a construction site production will be necessary. More detailed investigations into the transport problem will only be available carried out at a specific location.
