Gentlemen: 

SUBJECT:  POTENTIAL STEAM GENERATOR RELATED GENERATED REQUIREMENTS (GENERIC 
          LETTER NO. 82-32) 

The NRC staff has identified potential steam generator related generic 
requirements and is currently subjecting them to a value impact analysis. A 
major element if the staff's value impact will be an analysis being prepared
by our contractor, Science Applications, Inc. A copy of these draft report 
is provided for your review and will be modified to consider multiple steam 
generator tube ruptures in combination with other events along with single 
tube rupture scenarios. 

Any comments you may care to make, either individually or through Owners 
Groups, on the SAI report and on the probability and consequences of 
multiple tube ruptures scenarios would be considered in the staff's final 
value impact analysis if they can be provided within 30 days of the date of 
this letter. 

                                   Sincerely, 



                                   Darrell G. Eisenhut, Director 
                                   Division of Licensing
