FPL, the owner and licensee for St. Lucie Nuclear Plant (PSL) Units 1 and 2, has submitted a revised subsequent license renewal application (SLRA) for the Facility Operating Licenses for PSL Units 1 and 2 (Reference 1) and the first annual update (Reference 2). The License Renewal Rule, 10 CFR 54.21(6),

requires that each year following submittal of an LRA, and at least 3 months before scheduled completion of the NRC review, an update to the LRA must be submitted that identifies any change to the current licensing basis (CLB) of the facility that materially affects the content of the LRA including the Updated Final Safety Analysis Report Supplement.

In accordance with the License Renewal Rule, FPL has performed the second annual review of PSL Units 1 and 2 CLB changes since SLRA submittal to dete1111ine whether any sections of the SLRA were materially affected by these changes. As a result of this annual review, FPL identified one change to the PSL Units 1 and 2 CLB materially affecting SLRA content. A description of these changes and the corresponding affected SLRA content revisions are provided in Attachments 1 and 2 to this letter, respectively. Note that SLRA pages 3.3-93 and 3.4-72 were previously revised by references 3 and 4, respectively.

For ease of reference, the index of attached information is provided on page 3 of this letter. Attachment 2 includes associated revisions to the SLRA (Enclosure 3 Attachment 1 of Reference 1) denoted by strikethrough ( deletion) and/ or bold red underline (insertion) text. Previous SLRA revisions are denoted by bold black text. SLRA table revisions are included as excerpts from each affected table.
