PNP Prototype Plant Nuclear Process Heat. Half-yearly report 1st half 1986. Development of large metallic components for the circuits of Prototype plant for nuclear process heat (PNP). V class 2

Automatic translation: The experiments on the 10 MW URKO test heat exchanger in the KVK have been concluded (see point 1.2.1). The heat exchanger was removed and used Carrying out follow-up examinations in the Manufacturing plant in Neubeckum transported. At the Removal of the ZWT from the test container was a approx. 100 mm long crack in the weld seam of a Mounting plaster of the outer bundle cladding detected. A key goal of the follow-up exams is to identify the causes for this To fathom crack. With the 170 MW URKO heat exchanger, they are Construction work for the assembly Hot collector, holding jacket and hot branch completed and the drawings completed. For the remaining assemblies, the design work has largely been carried out.
