Florida Power & Light Company letter L-2018-205, Response to Request for Additional Information Regarding License Amendment Request to Reduce the Number of Control Element Assemblies, November 15,2018 (ADAMS Accession No. ML18319A043 In Reference 1, as supplemented by References 2 and 3, Florida Power & Light Company (FPL) requested an amendment to Renewed Facility Operating License NPF-16 for St. Lucie Unit 2. The proposed license amendment modifies the St. Lucie Unit 2 Technical Specifications (TS) by reducing the number of control element assemblies (CEAs) specified in the TS, from 91 to 87, to support permanent removal of four 4-element (mini-dual) CEAs from the reactor core. The proposed license amendment relatedly deletes a reference to the 4-element CEAs in an existing TS definition.

Subsequent to the above submittals, FPL was made aware of changes to a proposed St. Lucie Unit 2 TS page that are warranted, though editorial in nature. Accordingly, the enclosure to this letter provides the existing St. Lucie Unit 2 TS page marked up to show the latest proposed changes. The TS marked up page supersedes the corresponding page provided in Reference 1. No changes are proposed to the St. Lucie Unit 2 TS Bases.

The enclosure to this letter does not alter the conclusion in Reference 1 that the proposed amendment does not involve a significant hazards consideration pursuant to 10 CFR 50.92, and that there are no significant environmental impacts associated with this proposed change. In accordance with 10 CFR 50.91(b)(1), a copy of the proposed change is being forwarded to the designee for the State of Florida.

DEFINITIONS CHANNEL FUNCTIONAL TEST 1.6 A CHANNEL FUNCTIONAL TEST shall be the injection of a simulated signal into the channel as close to the primary sensor as practicable to verify OPERABILITY including alarm and/or trip functions.

CONTAINMENT VESSEL INTEGRITY 1.7 CONTAINMENT VESSEL INTEGRITY shall exist when:

a. All containment vessel penetrations required to be closed during accident conditions are either:
1. Capable of being closed by an OPERABLE containment automatic isolation valve system, or
2. Closed by manual valves, blind flanges, or deactivated automatic valves secured in their closed positions, except for valves that are open on an intermittent basis under administrative control.
b. All containment vessel equipment hatches are closed and sealed,
c. Each containment vessel air lock is in compliance with the requirements of Specification 3.6.1.3,
d. The containment leakage rates are within the limits of Specification 3.6.1.2, and
e. The sealing mechanism associated with each penetration (e.g., welds, bellows or 0-rings) is OPERABLE.

CONTROLLED LEAKAGE 1.8 CONTROLLED LEAKAGE shall be the seal water flow supplied from the reactor coolant pump seals.

CORE ALTERATION 1.9 CORE ALTERATION shall be the movement or manipulation of any fuel, sources, rea*ctivity control components, or other components affecting reactivity within the reactor vessel with the vessel head removed and fuel in the vessel. Exceptions to the above include sl1aree (4 fiR!JCfel'l)
