NRC Information Notice 97-26, "Degradation in Small-Radius U-Bend Regions
of Steam Generator Tubes," dated May 19, 1997.                           
                                                                         
The NRC is issuing this information notice to disseminate information    
about recent degradation affecting small-radius (rows 1 and 2) U-bend    
regions of tubes in recirculating steam generators, in order to alert    
utilities to potential problems in ensuring the integrity of the         
small-radius U-bends, and to provide information about action taken by   
certain licensees to ensure adequate integrity.

NRC Information Notice 97-27, "Effect of Incorrect Strainer Pressure Drop
on Available Net Positive Suction Head," dated May 16, 1997.             
                                                                         
The NRC is issuing this information notice to alert addressees that two  
licensees of boiling-water reactors have recently identified inaccurate  
assumptions in licensing-basis calculations for net positive suction     
head.
