50 Mwe Test Loop. Monthly Report,July--August 1974 (Weeks 27--35).

摘要

Up till August 12work was carried out on the installation,which was not in operation during that time. After August 12continuous operation was resumed again. After preoperational tests had been performed,the sodium system was filled up with sodium again on August 14. The WDE is now connected up again,while the GDE evaporator and the IHX are no longer connected up to the system. The installation was connected up thermally for the first time again on August 23,this being followed immediately by a test of ESD 105at 50kg/cm sub 2 . The TVP was in operation with the new connection. The turbine functioned excellently,the only leak observed being one in the flanged joint,which developed after a short period in operation. Since this leak cannot be repaired during operation,the turbine was taken out of service again and the repair is to be carried out in week 38during the next period. Since the TVP and all three furnaces were not available,the installation could not be operated under full load conditions during this period,the maximum load reached being 50percent. For this reason no tests were carried out on the steam generator. During the next period a start is to be made on repeating the steady-state measurements.
