Problems with steam generators now cause
major public health and safety risks. |
 |
 |
NSP was the 13th electric utility to sue
Westinghouse because steam generator tubes sold by Westinghouse have experienced
unanticipated and premature degradation. |
 |
This degradation causes cracks to form and grow, and
leak primary water into the secondary loop. It can cause tubes to rupture. |
Internal nuclear industry documents secured
by the Prairie Island Coalition during NSP's lawsuit emphasize the seriousness
of tube cracking. |
