NS SAVANNAH FUEL DEVELOPMENT PROGRAM. THERMAL SHOCK CONDITIONS AND HISTORY OF OPERATING CONDITIONS IN HEAT TRANSFER FACILITY FOR NS SAVANNAH 25 ROD PARTIAL PROTOTYPE FUEL ASSEMBLY

Pressure drop and thermal shock tests on the N.S. Savannah 25 rod partial prototype fuel assembly are presented along with a history of operating conditions in the General Electric Heat Transfer and Fluid Flow Facility. Data is limited to test conditions, equipment and procedure. A partial prototype fuel rod assembly was given 18 thermal cooling shocks from a temperature of 520F. The total cooling range averaged 175F at a mean rate of 32 degrees per minute. Details of the initial and final conditions and shock rates are given in tabular form. The fuel rod assembly was operated from room conditions of 70F and a pressure of 20 psig to maximum temperature and pressure of 540F and 1250 psig. Flow rates varied from 2 to 23 lbs. water per sceond. The chronological history of operating conditions is shown graphically, and tabular data is given on the average time at operating conditions and water resistivity.
