GINNA NUCLEAR POWER STATION Inservice Inspection Report 1990 1999 Interval, First Outage 1990 Attachment II Erosion/Corrosion (Minwall) Summary Report This section provides a detailed listing of components and associated examination results on items that were inspected during the 1990 Ginna Outage. A total of 312 components were examined.

Chart number 1 shows by graphic display the types of components that were examined. This chart also provides an overall display of

,components in relationship to the percentage of nominal wall remaining. Out of a total number of 312 components; 17 components had less than 65X nominal wall remaining.

Table number 1 provides a complete listing of items by components that were examined during the 1990 Ginna Outage. If the listed component had examination results in 1989, the results of that, examination is specified along with the results of the 1990 inspection. The percentage of Nominal Wall remaining by component is also included for reference.

1990 Minwall Examination Program and Results:

The following listing identifies the systems, the types of components within the system, the examination result breakdown as a percentage of nominal wall remaining as well as the reference drawing that identifies the component within the specified system.
