Dear Mr. O'Reilly:

This supplemental response provides clarification of Carolina Power and Light Company's (CP&L's) long term corrective actions as described in our response of Feb rua ry 29, 1984.

In that original responge, we indicated the untriue features of the old H. B. Robinson steam generators and identified several corrective actions which were based on continued use of the old steam generators. Howeve r, as was also indicated in the original response, the old steam generator tube bundles are currently being replaced with new bundles which will eliminate the mejor cause of the violation.

With respect to long term corrective actions in utiltains the new steam generator tube bundles, CP&L is committed to carrying forward the lessons learned with the old steam generators. These lessona havn already been reflectet in numerous corrective actions including new and upgraded secondary water systems (condensate polishers, makeup water treatment, and condensate storage tank bladder) AVT chemistry control, removal of copper from the secondary system, increased steam generator blow-down capability, and a better understanding of the Eddy Current inspection process.

In the area of Eddy Lurrent inspections, CP&L is committed to utilising the experience gained in the last several years for future steam generator inspection.e.

These inspections will be carriel out in accordance with the H. B. Robinson Technical Specifications, Corporate Quality Assurance requirements, and will Oh

l utilise standard industry practices.

In addition, as a result of lessons learned.

l specific management attention will continue to be directed towards shif t manning schedules for the data evaluati, personnel and the scope of any data reverifica-l tion which would be based on the specific Eddy Current results. CP&L believes d'

j that the dove actions are adequate to prevent a recurrence of the violation.
