NOZZLE DEVELOPMENT AND TESTING PROGRAM FOR ENERGENCY CORE COOLING SYSTEM

Results are presented on a study made to determine the best design for the Emergency Core Cooling (ECC) system penetration into the buffer seal. Through the use of dye penetrant methods and sectioning, it was found that the pin type weld may be reliably performed. The study also concludes that the thermal sleeve attachment method is satisfactory, thereby demonstrating that the rolling technique is suitable for the reactor installation. There was no evidence of failure of the flange or the piping joint after both hydrostatic and thermal shock tests.
