Gentleman: 

RE:  PERIODIC UPDATING OF FINAL SAFETY ANALYSIS REPORTS (FSARs) (GENERIC 
     LETTER 81-06) 

The Commission approved the rule 50.71(e) (copy enclosed) entitiled, 
"Periodic Updating of FInal Safety Analysis Reports" and published the rule 
in the Federal Register on May 9, 1980. The rule became effective on July 
22, 1980. 

Although this new rule applies to holders of operating licenses for power 
reactors, we believe your organization should be aware of it, since within 
24 months after issuance of an operating license or July 22, 1982, whichever
is later, the original FSAR submitted as a part of the OL application must 
be updated in the specific manner provided in the rule. Thereafter, it must 
be updated at least annually. Each update must relfect all changes up to six
months prior to the filling of the update. 

ALthough the rule itself is self-explanatory, several questions have been 
asked regarding the FSAR's legal status, format and content, and we have 
provided the enclosed guidance. 

Further questions should be directed to the Project Manager for you 
facility. 

                              Sincerely, 


                              Darrell G. Eisenhut, Director 
                              Division of Licensing 

Enclosure:
As stated
