Four Indication Notification Reports (INR) were initiated, describing a total of 20 relevant (recordable) indications. Two of these indications, which were identified on Indication Notification Report INR-VYR24-0 1, were weld repaired. The remaining 18 indications was dispositioned "use-as-is," based on evaluation and recommendation by vendor and Entergy engineering personnel.

These modifications were examined in RFO-25 and RFO-26, and the results of those examinations are found in the exhibits related to those outages.
