   Has there been any documented failure attributed to design oversight    related to the above subject? Nozzle fails since the stiffness has    not been properly analyzed. Question arises since over the life of    the piping some of thse nozzle leaks or showed sign of thinning and    would requre repair. Either by welding or a cettain type of    enclousres whoich in effect would change the stifness. Since the    practice is allowed (contractor does not normally ask impact    re:WRC297) i was just wondering how far do we really have to go as    far as analyzing/evaluating nozzle jointis concewrn
