Summary
A 42-day test of the NUSU test element at a clad temperature of about 1275 deg F did not reveal evidence of leaks. Metallographic examinntion of the clad material is in progress. A compilation of computer programs useful in physics evaluation calculations was completed. A total of 13 codes are now available on a routine basis. Experimental data on the AEC sponsored superheat critical experiments were compiled and cataloged. Calculational procedures used by CEND and GNEC were collected, and the initial application of these methods to selected critical experiments was started. The preliminary design of the annular multitube fuel element was modified, primarily to reduce the stress levels existing near the end seals. The major modifications include a transition piece between the fuel region and the end seals, a larger plenum containing at least a 380 deg stress-relieving bend of the steam tubes at the top of the element, and an expanded and flared tubesheet construction. A weld evaluation program was initiated to determine the most suitable procedure for the tube to tube-sheet configuration. (J.R.D.)
