2.1 CONCLUSION

The review of industry information, NRC generic communications, and St.

Lucie Units I and 2 operating experience identified no additional aging effects beyond those discussed In Subsection 3.2.2. Tables 3.2-1 through 3.2-5 contain the results of the aging management review for the Engineered Safety Features Systems and summarize the aging effects requiring management.

The aging effects requiring management are adequately managed by the following programs:

St. Lucie programs consistent with the corresponding programs in the GALL Report:

"* ASME Section Xl, Subsections IWB, IWC, and IWD Inservice Inspection Program

"* Boric Acid Wastage Surveillance Program

"* Chemistry Control Program St. Lucie plant-specific programs:

"* Galvanic Corrosion Susceptibility Inspection Program

"* Periodic Surveillance and Preventive Maintenance Program

"* Systems and Structures Monitoring Program Based on the evaluations provided in Appendix B for the programs listed above, aging effects are adequately managed so that the Intended functions of the Engineered Safety Features Systems components listed in Tables 3.2 1 through 3.2-5 are maintained consistent with the St. Lucie Units 1 and 2 CLBs for the period of extended operation.
