NRC Information Notice 95-01, "DOT Safety Advisory:  High Pressure       
Aluminum Seamless and Aluminum Composite Hoop-Wrapped Cylinders," to be  
issued January 4, 1995.                                                  
                                                                         
The NRC is issuing this information notice to alert addressees to a      
safety concern for workers identified in the safety advisory recently    
issued by the Research and Special Programs Administration of the U.S.   
Department of Transportation (DOT).  The DOT notice advises users of     
certain high pressure cylinders made of aluminum alloy 6351-T6 to follow 
precautionary measures to prevent or mitigate cylinder ruptures.

NRC Information Notice 86-108, Supplement 3, "Degradation of Reactor     
Coolant System Pressure Boundary Resulting from Boric Acid Corrosion," to
be issued January 5, 1995.                                               
                                                                         
The NRC is issuing this information notice supplement to alert addressees
to two recent significant incidents of boric acid-induced corrosion of   
ferritic steel components on the pressure boundary of pressurized water  
reactors.  These incidents indicate that there may still be a general    
lack of awareness of the ambient conditions that can lead to boric acid  
attack.
