            COMBINED WITH SINGLE FAILURE (Generic Letter No. 81-32) 

The staff has completed its review of the Generic Electric BWR Owner Group 
report dated December 29, 1980 pertaining to the subject NUREG-0737 item. 
This report was prepared for the participating applicants/licensees 
identified in the enclosure. 

This is to advise you that we have found the response contained in this 
report to be acceptable on a generic basis. However, in order to confirm the
applicability of this report to your facility we request that you provide 
verification that the assumptions and initial conditions used in the 
analyses are representative for your plant(s). Licensees and applicants are 
to provide this information according to the following schedule: 

     a.   Licensees of operating plants within 90 days of receipt of this  
          letter, 
     b.   Applicants for operating licensees within 90 days of receipt of  
            this letter and 
     c.   The remaining participating utilities within 30 days of docketing 
            of the FSAR. 

If the conditions and assumptions used in the analyses are nor representa-
tive, the licensee should identify the major design differences between the 
plant analyzed and the licensee's plant. A qualitative assessment of the 
effect these differences have on the analyses can be offered by the 
licensee; however, if this assessment lacks technical support, a schedule 
for providing plant specific analyses will be required. For applicants for 
operating licenses the completion dates for any required analyses should be 
consistent with your review schedule. 

The above information is requested in accordance with Sections 103.b(3) and 
161.c of the Atomic Energy Act of 1954, as amended. The request for 
information was approved by OMB under clearance number 3150-0065 which
