Subject:

Supplement to Application to Add Limiting Condition for Operation (LCO) 3.0.6 to the Technical Specifications

Reference:

Florida Power & Light Company letter L-2018-049, "Application to Add Limiting Condition for Operation (LCO) 3.0.6 to the Technical Specifications," May 29, 2018 (ADAMS Accession No. ML18151A472)

In the referenced letter, Florida Power & Light Company (FPL) submitted a request for an amendment to the technical specifications (TS) for St. Lucie Units 1 and 2, Turkey Point Units 3 and 4, and, on behalf ofNextEra Energy Seabrook, LLC, for Seabrook Station. The proposed amendments would modify the TS to incorporate the provisions of Limiting Condition for Operation (LCO) 3.0.6 in the improved standard TS (ISTS), which provide the actions to be taken when the inoperability of a support system results in the inoperability of related supported systems.

In addition, the proposed change adds a new Safety Function Determination Program to the administrative section of the TS to ensure that a loss of safety function is detected and appropriate actions are taken when using the provisions ofLCO 3.0.6.

A review of the license amendment request identified inconsistencies between sections of the request regarding the wording of two proposed changes for St. Lucie, Turkey Point, and Seabrook, and an omission in a proposed change that reformats a TS action in the Turkey Point TS. As discussed in the enclosure, this supplement clarifies the proposed changes as discussed in a conference call with the NRC staff on February 28, 2019. In addition, amendments to the Turkey Point TS occurred subsequent to submittal of the request to adopt LCO 3.0.6. The attachment to the enclosure provides revised markups of the proposed changes to the Turkey Point TS, which supersede the corresponding markups in the referenced letter.

This letter contains no new or revised regulatory commitments.

ENCLOSURE Enclosure L-2019-055 Page 1 of 2 Clarification of Proposed Changes to Technical Specification 3.8.1.1 for St. Lucie, Turkey Point, and Seabrook The license amendment request to adopt LCO 3'.0.6 (LAR) adds two new requirements to the actions in St. Lucie, Turkey Point, and Seabrook Technical Specification (TS) 3.~.1.1, "A.C. Sources

- Operating." First, as discussed in section 2.0 of the LAR, "Detailed Description," the following requirement is added to action a, which addresses an inoperable offsite A.C. circuit:

"Within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> from discovery of no offsite power to one train concurrent with inoperability of redundant required feature(s), declare required feature(s) with no offsite power available inoperable when its redundant required feature(s) is inoperable."

The second new requirement is added to action d (St. Lucie) and action e (Seabrook and Turkey Point) for two inoperable offsite A.C. circuits:

Within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> from discovery of two offsite circuits inoperable with inoperability of redundant required feature(s), declare required feature(s) inoperable when its redundant required feature(s) is inoperable."

Section 3.0 of the LAR, "Technical Evaluation," also discusses these two new requirements.

However, the wording of the proposed changes in section 3.0 as shown below is different from that in section 2.0.

"Declare required feature(s) with no offsite power available inoperable when its redundant required feature(s) is inoperable within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> from discovery of no offsite power to one train concurrent with inoperability of redundant required feature(s)."

"Declare required feature(s) inoperable when its redundant required feature(s) is inoperable within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> from discovery of two offsite circuits inoperable concurrent with inoperability of redundant required feature(s)."

Although the wording of the actions is inconsistent between sections 2.0 and 3.0 of the LAR, the directions provided by the actions are the same. The preferred wording for the proposed changes is the wording included in section 2.0 of the LAR. The markups of TS 3.8.1.1 included in the LAR for Seabrook and St. Lucie contain the preferred wording. The attachment to this enclosure provides a revised markup of TS 3.8.1.1 for Turkey Point that incorporates the preferred wording.

Additional Revisions to the Proposed Changes for Turkey Point The LAR revises TS 3.8.1.1, actions c and e, in part, by reformatting the actions from a paragraph to a list of discrete steps. However, the list of steps associated with action c omitted the requirement to perform surveillance requirement (SR) 4.8.1.1.1.a on the remaining startup transformer and associated circuits within one hour and at least once per eight hours thereafter. The revised markup of TS 3.8.1.1 in the attachment to this enclosure adds the requirement to perform SR 4.8.1.1.1.a to the list of steps in action c.

The proposed change to reformat TS 3.8.1.1 actions c and e included a requirement for a four-hour NRC notification. However, Amendments 279 and 274 lR-eference 1] eliminated the four-hour

Enclosure L-2019-055 Page 2 of2 notification requirem~nts.. As a result, the revised markup of TS 3.8.1.1 in the attachment to this enclosure incorporates this change.,

Amendments 284 and 278 [Reference 2] modified actions a and b in TS 3.8.1.1 to permit use of risk informed completion times. The revised markup of TS 3.8.1.1 in the attachment to this enclosure incorporates this change.

The LAR proposed adding new administrative TS 6.7.4.n, "Safety Function Determination Program (SFDP)." However, Amendments 281 and 275 [Reference 4], Amendments 282 and 276 [Reference 3t and Reference 2 added administrative TS 6.7.4. n, o, and p, respectively. Therefore, the designation of the proposed new administrative TS for the Safety Function Determination Program is revised to TS 6.7.4. q. The revised markup of TS 6.7.4 in the attachment to this enclosure incorporates this change.

!INSERT SFDP Risk Informed Completion Time Program This program provides controls to calculate a Risk Informed Completion Time (RICT) and must be implemented in accordance with NEI 06-09, "Risk-Informed Technical Specifications Initiative 4b: Risk-Managed Technical Specifications (RMTS) Guidelines," Revision 0-A, November 2006. The program shall include the following:

a.

The RICT may not exceed 30 days;

b.

A RICT may only be utilized in MODES 1 and 2;

c.

When a RICT is being used, any plant configuration change within the scope of the Risk Informed Completion Time Program must be considered for the effect on the RICT.

1.

For planned changes, the revised RICT must be determined prior to implementation of the change in configuration.

2.

For emergent conditions, the revised RICT must be determined within the time limits of the Required Action Completion Time (i.e., not the RICT) or 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after the plant configuration change, whichever is less.

3.

Revising the RICT is not required if the plant configuration change would lower plant risk and would result in a longer RICT.

d.

Use of a RICT is not permitted for entry into a configuration which represents a loss of a specified safety function or inoperability of all required trains of a system required to be OPERABLE.

e.

If the extent of condition evaluation for inoperable structures, systems, or components (SSCs) is not complete prior to exceeding the Completion Time, the RICT shall account for the increased possibility of common cause failure (CCF) by either:

1.

Numerically accounting for the increased possibility of CCF in the RICT calculation, or

2.

Risk Management Actions (RMAs) not already credited in the RICT calculation shall be implemented that support redundant or diverse SSCs that perform the function(s) of the inoperable SSCs, and, if practicable, reduce the frequency of initiating events that challenge the function(s) performed by the inoperable SSCs.

g. Safety Function Detennination Program (SFDP)

L-2019-055 Attachment Page 9 of9 11-us program ensures loss of safety function is detected and appropriate action taken. Upon entry into LCO 3.0.7, an evaluation shall be made to determine if loss of safety function exists.

Additionally, other appropriate actions may be taken as a result of the support system inoperability and corresponding exception to entering supported system ACTIO s. This program implements the reguirements of LCO 3.0.7. The SFDP shall contain the following:

a.

Provisions for cross train checks to ensure a loss of the capability to perform the safety function assumed in the accident analysis does not go undetected,

b. Provisions for ensuring the plant is maintained in a safe condition if a loss of function condition exists,

c.

Provisions to ensure that an inoperable supported system's completion time is not inappropriately extended as a result of multiple support system inoperabilities, and

d. Other appropriate limitations and remedial or compensatory actions.

A loss of safety function exists when, assuming no concurrent single failure, no concurrent loss of offsite power, or no concurrent loss of onsite diesel generator(s), a safety function assumed in the accident analysis cannot be performed. For the purpose of this program, a loss of safety function may exist when a support system is inoperable, and:

a. A reguired system redundant to the system(s) supported by the inoperable support system is also inoperable, or

b. A reguired system redundant to the system(s) in turn supported by the inoperable supported system is also inoperable, or

c. A reguired system redundant to the support system(s) for the supported systems (a) and (b) above is also inoperable.

The SFDP identifies where a loss of safety function exists. If a loss of safety function is determined to exist by this program, the appropriate ACTIO s of the LCO in wluch the loss of safety function exists are reguired to be entered. When a loss of safety function is caused by the inoperability of a single Technical Specification support system, the appropriate ACTIONs to enter are those of the support system.
