SEMI-REMOTE CONNECTOR FOR FISSION PRODUCT CASKS
A miniature Hanford connector was designed which has three jaws, operated by one bolt, that compress flanges containing a non-reuseable, belleville spring type gasket. The flange sealing surfaces are located in corners and are protected from damage. Three connectors were tested for helium leakage rates at temperatures and pressures up to 520 deg C and 500 psig. All three had leak rates of less than 1 x 10/sup -5/ cc/sec helium measured at standard temperature and pressure. The connector withstood a vibration test without a detectable increase in the leak rate. The frequency of the vibration, normal to the gasket, was varied between 7 cps and 450 cps at accelerations ranging between 0.75 and 1.5 g. The connectors worked well mechanically, requiring 100 lb-ft torqus for closure. The connector was tested using a flat 1/ 8 in. thick Teflon gasket instead of the stainless steel Conoseal'' gasket. At room temperature and 500 psig the Teflon gasket had a leak rate of less than 1 x 10/sup -4/ cc/sec stp He. The sealing surfaces demonstrated resistance to damage by abrasive grit. (auth)
