Reliability of various tube-to-tubesheet weld configurations. [LMFBR]
Through the application of FMEA and FTA Techniques the reliabilities of various tube-to-tubesheet weld configurations consisting of different combinations single or duplex tubes and single or double tubesheets with or without leak detection are investigated for application to LMFBR steam generator design. Based on substantial failure experience accumulated on PWR units, the study confirms the high reliability these welds possess and in particular identifies the tube-to-boss fillet weld as the most efficient, reliable design.
