1 INTRODUCTION The NRC Commissioners have requested in their SRMs dated July 31,1989, February 15,1991 and March 5,1991, that new plant designs provide a discussion of how operational experience has been incorporated into the design process. This report addresses the manner in which operational experience has been incorporated into the design of the AP600.

PROCESS Generic Letters and IE Bulletins for the time period January 1,1980 to December 31,1997 and Circulars,Information Notices and AEOD Reports for the time period January 1,1980 to

, April 20,1996 were reviewed to determine applicability to the AP600 design certification.

The dispositions of individual documents can be broken down into the following categories:

=

Not Applicable to the AP600 design (e.g., BWR only, B&W facilities only, not applicable to commercial reactors)

=

Not Applicable to the design certification due to other reasons. For example:

Procurement issue - These issues were determined not to be applicable to the design certification phase.

Administrative communications - These items were documents tluit provide administrative information (e.g., scheduling of meetings, fonvarding other documents, etc.)

Procedural issue - These items were concerned with either lack of proper procedures of failure to comply with procedures.

Plant specific / isolated event - These issues were concluded to be isolated events at specific plants with no generic conclusions or impacts.

Maintenance / Surveillance issues - These issues were concluded to be related to mhintenance or surveillance of a system or component.

Bulletins and Generic I.etters identified as Procurement, Procedural, or Maintenance / Surveillance Issues will be reviewed and addressed by the Combined License Applicant.

Applicable to the AP600 design certification in which case the proper SSAR Section reference is given Operational Assessment for AP600 March 1998 o:\rev2\3073w.r02:ll>432s98
