U. S. Nuclear Regulatory Commission Attn: Document Control Desk Washington, D. C. 20555 Re: St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 Pro osed Chan e to Emer enc Plan Table 3-1: Classification of Emer encies Pursuant to 10 CFR 50.54(q), Florida Power & Light Company (FPL) requests approval, prior to implementation, of a change to the St. Lucie Plant Radiological Emergency Plan.

The proposed change clarifies the criteria used in the classification of a radiological emergency. Emergency action levels remain consistent with the classification criteria currently approved by the NRC. Attachment 1 provides an explanation of changes to the emergency classification table contained in the St. Lucie Plant Radiological Emergency Plan, Table 3-1.

Attachment 2 provides a draft revision of Table 3-1 as it would appear in the Radiological Emergency Plan. Vertical lines are used to indicate changes to the table.

The proposed change was reviewed by the St. Lucie Plant Facility Review Group on July 14, 1998. On receipt of approval from the NRC of the proposed change, FPL will revise the St.

Lucie Plant Emergency Plan and Emergency Plan Implementing Procedure EPIP-01 to implement the revised classification criterion.

Ifyou have any questions, please contact Mr. Ed Weinkam at 561-467-7162.

Attachment 1 Explanation of Proposed Changes to St. Lucie Radiological Emergency Plan Table 3-1; Emergency Classification Table

Background:

Emergency Classification Table 3-1 (Revision 34 of the Emergency Plan) was reviewed to identify sections where the descriptive instruction to licensed operators and Plant management could be improved. Specifically, the review addressed areas where clarification could be provided to emergency action levels without changing the intent of the classification criteria. Regulatory guidance and industry standards have been consulted as part of this review. The following changes are proposed:

The proposed change clarifies the criteria used in the classification of a radiological emergency. Emergency action levels remain consistent with the classification criteria currently approved by the NRC. Attachment 1 provides an explanation of changes to the emergency classification table contained in the St. Lucie Plant Radiological Emergency Plan, Table 3-1.

Attachment 2 provides a draft revision of Table 3-1 as it would appear in the Radiological Emergency Plan. Vertical lines are used to indicate changes to the table.

The proposed change was reviewed by the St. Lucie Plant Facility Review Group on July 14, 1998. On receipt of approval from the NRC of the proposed change, FPL will revise the St:

Lucie Plant Emergency Plan and Emergency Plan Implementing Procedure EPIP-01 to implement the revised classification criterion.

Ifyou have any questions, please contact Mr. Ed Weinkam at 561-467-7162.
