TITLE OF THE INVENTION INDUSTRIAL TECHNIQUE ABSTRACT An illustrative embodiment of the invention has a group of three concentrically disposed banks of helical steam generator tubes. Shrouds interposed between each of these three tube banks establish liquid barriers between the individual banks that prevent liquid sodium (or other shell side working fluid) from enjoying free communication throughout all of the tube banks. In this way, potentially damaging leakage between the shell side working fluid and the water within one of the tube banks can be isolated through discontinuation of the shell side working fluid and feedwater flow to the leaking bank, thereby permitting the remaining sound tube banks to continue functioning.
