TURKEY POINT - UNITS 3 & 4 3/4 8-2 AMENDMENT NOS. 278 AND 273

UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION AMENDMENT NO. 278 TO RENEWED FACILITY OPERATING LICENSE NO. DPR-31 AMENDMENT NO. 273 TO RENEWED FACILITY OPERATING LICENSE NO. DPR-41 FLORIDA POWER & LIGHT COMPANY TURKEY POINT NUCLEAR GENERATING UNIT NOS. 3 AND 4 DOCKET NOS. 50-250 AND 50-251

1.0 INTRODUCTION

By application dated June 29, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17195A569), Florida Power & Light Company (the licensee),

requested changes to the Technical Specifications (TS) for Turkey Point Nuclear Generating Unit Nos. 3 and 4 (Turkey Point 3 and 4). The proposed changes would modify TS requirements for mode change limitations in Limiting Condition for Operation (LCO) 3.0.4 and Surveillance Requirement (SR) 4.0.4 to adopt the provisions of Industry/Technical Specifications Task Force (TSTF) change 359, "Increase Flexibility in Mode Restraints." The availability of TSTF-359 for adoption by licensees was announced in the Federal Register on April 4, 2003 (68 FR 16579).

TSTF-359 is one of the industry's initiatives under the risk-informed TS program. These initiatives are intended to maintain or improve safety while reducing unnecessary burden, and to make TS requirements consistent with the Nuclear Regulatory Commission's (NRC's or the Commission's) other risk-informed regulatory requirements, in particular, the maintenance rule.

The current Standard Technical Specifications (STS, NUREG 1430-1434) specify that a nuclear power plant cannot go to higher modes of operation 1 (i.e., move toward power operation) unless all TS systems, normally required for the higher mode, are operable. This limitation is included (with several exceptions for some plants) in LCO 3.0.4 and SR 3.0.4.

LCO 3.0.4 and SR 3.0.4 in the STS currently state, in part, that when an LCO or SR is not met, "entry into a MODE or other specified condition in the applicability shall not be made except when the associated actions to be entered permit continued operation in the MODE or other specified condition in the applicability for an unlimited period of time." The industry believes that this requirement is unnecessarily restrictive and can unduly delay plant startup while considerable resources are being used to resolve startup issues that are risk insignificant or low risk. A maintenance activity that takes longer than planned can delay a mode change and adversely impact a utility's orderly plant startup and return to power operation. The objective of 1 MODE numbers decrease in the transition "up to a higher mode of operation"; power operation is MODE 1.

Enclosure 3

the proposed change is to provide additional operational flexibility without compromising plant safety.

The licensee is proposing the following variations from the TS changes described in TSTF-359, Revision 9, dated April 4, 2003. Specifically,

1. The Turkey Point 3 and 4 TSs utilize different numbering and titles than NUREG-1431, "Standard Technical Specifications -Westinghouse Plants," on which TSTF-359 was based. Additionally, the Turkey Point 3 and 4 TS do not contain all of the TS that were revised by TSTF-359. These differences are administrative in nature.
2. The licensee proposed retaining the existing exceptions to SR 4.0.4 in the Turkey Point 3 and 4 TSs, and not including the paragraph below that is included in TSTF-359 for the Bases of SR 3.0.4 in the proposed Bases for SR 4.0.4.

The precise requirements for performance of SRs are specified such that exceptions to SR 3.0.4 are not necessary. The specific time frames and conditions necessary for meeting the SRs are specified in the Frequency, in the Surveillance, or both. This allows performance of Surveillances when the prerequisite condition(s) specified in a Surveillance procedure require entry into the MODE or other specified condition in the Applicability of the associated LCO prior to the performance or completion of a Surveillance. A Surveillance that could not be performed until after entering the LCO's Applicability, would have its Frequency specified such that it is not "due" until the specific conditions needed are met. Alternately, the Surveillance may be stated in the form of a Note, as not required (to be met or performed) until a particular event, condition, or time has been reached. Further discussion of the specific formats of SRs' annotation is found in Section 1.4, Frequency.

The Turkey Point 3 and 4 TSs have not been converted to the STS (NUREG 1431). The STS list "specified frequencies," which consist of the requirements of the Frequency column of each SR, as well as certain Notes in the Surveillance column that modify performance requirements. The Turkey Point 3 and 4 TSs do not list individual SRs that specify the timeframes and conditions necessary for meeting the SRs to allow entry into the mode of condition of applicability without having performed the SR. Therefore, the licensee is proposing to retain existing SR 4.0.4 exceptions in the TS. This will allow the performance requirements to be met, which may include Notes.

Removing SR 4.0.4 exceptions from the Turkey Point 3 and 4 TS would not capture these requirements. Therefore, the NRC Staff finds this variation acceptable.

3. The licensee proposes to modify the LCO 3.0.4.b exclusion for auxiliary feedwater (AFW) in TSTF-359 from "LCO 3.0.4.b not applicable when entering MODE 1" to "LCO 3.0.4.b is not applicable to the required auxiliary feedwater trains when entering MODE 1." This variation is evaluated in Section 3.1.1 of this safety evaluation.
4. TSTF-359 and the model safety evaluation refer to Regulatory Guide (RG) 1.182, "Assessing and Managing Risk before Maintenance Activities at Nuclear Power Plants." However, RG 1.182 was withdrawn in November 2012 because it was redundant to the inclusion of its information in RG 1.160, "Monitoring the Effectiveness of Maintenance at Nuclear Power Plants." Therefore, the proposed bases for Turkey Point 3 and 4 LCO 3.0.4 refer to RG 1.160 rather than RG 1.182. This is an administrative variation.

The proposed changes to LCO 3.0.4 and SR 4.0.4 would allow, for systems and components, mode changes into a TS condition that have specific required actions and completion times.

The licensee will utilize the LCO 3.0.4 and SR 4.0.4 allowances only when they determine that there is a high likelihood that the LCO will be satisfied within the LCO completion time, after the mode change. In addition, the LCO 3.0.4 and SR 4.0.4 allowances can be applied to values and parameters in specifications when explicitly stated in the TS (nonsystem/component TS such as: Reactor Coolant System Specific Activity). These changes are in addition to the current mode change allowance when a required action has an indefinite completion time. The LCO 3.0.4 and SR 4.0.4 mode change allowances are not permitted for the systems and components (termed "higher risk") listed in Section 3.1.1 of this safety evaluation, "Identification of Risk-Important TS Systems and Components," for the modes specified. Two examples are:

(1) Westinghouse plants cannot transition from Mode 5 to Mode 4 without a High Head Safety Injection System train operable; and, (2) Westinghouse plants cannot transition up into any mode with an inoperable required emergency diesel generator.

2.0 REGULATORY EVALUATION

In Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Section 36, the Commission established its regulatory requirements related to the content of TS. Pursuant to 10 CFR 50.36, TS are required to include items in the following five specific categories related to station operation: (1) safety limits, limiting safety system settings, and limiting control settings; (2)

LCOs; (3) SRs; (4) design features; and (5) administrative controls. The rule does not specify the particular requirements to be included in a plant's TS. As stated in 10 CFR 50.36(c)(2)(i),

the "Limiting conditions for operation are the lowest functional capability or performance levels of equipment required for safe operation of the facility. When a limiting condition for operation of a nuclear reactor is not met, the licensee shall shut down the reactor or follow any remedial action permitted by the technical specifications .... " By convention, the LCOs are contained in Sections 3.1 through 3.1 O of the STS and Sections 3/4.1 through 3/4.12 for Turkey Point 3 and 4. TS Section 3/4.0, "Applicability," provides details or ground rules for complying with the LCOs. LCO 3.0.4 and SR 4.0.4 address requirements for LCO compliance when transitioning between modes.

Technical specifications have taken advantage of risk technology as experience and capability have increased. Since the mid-1980's, the NRC has been reviewing and granting improvements to TS that are based, at least in part, on probabilistic risk assessment (PRA) insights. In its final policy statement on TS improvements of July 22, 1993 (58 FR 39132), the Commission stated that it expects that licensees will utilize any plant-specific PRA or risk survey in preparing their TS-related submittals. In evaluating these submittals, the NRC staff applies the guidance in RG 1.174, Revision 3, "An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis," dated January 2018 and in RG 1.177, Revision 1, "An Approach for Plant-Specific, Risk-Informed Decisionmaking: Technical Specifications," dated May 2011. The NRC staff has appropriately

adapted this guidance to assess the acceptability of upward mode changes with equipment inoperable. This review had the following objectives:

  • To ensure that the plant risk does not increase unacceptably during the actual implementation of the proposed change (e.g., when the plant enters a mode while an LCO is not met). This risk increase is referred to as "temporary."
  • To compare and assess the risk impact of the proposed change to the acceptance guidelines of the Commission's Safety Goal Policy Statement (51 FR 30028), as documented in RG 1.174. The risk impact, which is measured by the average yearly risk increase associated with the change, aims at minimizing the "cumulative" risk associated with the proposed change so that the plant's average baseline risk is maintained within a minimal range.
  • To assess the licensee's ability to identify risk-significant configurations resulting from maintenance or other operational activities and take appropriate compensatory measures to avoid such configurations.

The NRC staff reviewed licensee reliance on 10 CFR 50.65(a)(4) for the non-higher-risk systems and components, and related guidance to assess and manage the risk of upward mode changes. The Commission has found that compliance with the industry guidance for implementation of 10 CFR 50.65(a)(4), as endorsed by RG 1.160, "Monitoring the Effectiveness of Maintenance at Nuclear Power Plants," and mandated by LCO 3.0.4, SR 4.0.4, and SR 4.0.3, satisfies the configuration risk management objectives of RG 1.177 for TS surveillance interval and completion time extensions2 . The licensee's reliance on 10 CFR 50.65(a)(4) processes that are consistent with the provisions of the NRG-endorsed industry guidance was also found to be adequate for managing the risk of missed surveillances as described in the Federal Register on September 28, 2001 (66 FR 49714).

The NRC staff review also had the objective of ensuring that existing NRC inspection programs have the necessary controls in place to allow the NRC staff to oversee the implementation of the proposed change, reliance on 10 CFR 50.65(a)(4) processes or programs, and the ability to adequately assess the licensee's performance associated with risk assessments. The review encompassed inspection procedures (i.e., NRC Inspection Procedure 62709 dated December 28, 2000, "Configuration Risk Assessment and Risk Management Process," and NRC Inspection Procedure 71111.13 dated January 17, 2002, "Maintenance Risk Assessments and Emergent Work Control"), the significance determination process (i.e., "Maintenance Risk Assessment and Risk Management Significance Determination Process"), enforcement guidance (i.e., Enforcement Manual Section 7.11, "Actions Involving the Maintenance Rule"),

and the associated reactor oversight process.

2.1 Proposed Change to Turkey Point 3 and 4 LCO 3.0.4 and SR 4.0.4 Currently, Turkey Point 3 and 4 LCO 3.0.4 does not allow entrance into a higher mode (or other specified condition) in the applicability when an LCO is not met, except when the associated Actions to be entered permit continued operation in that mode or condition indefinitely, or a specific exception is granted. Similarly, when an LCO's surveillances have not been met within 2 RG 1.182 was superseded by RG 1.160, "Monitoring the Effectiveness of Maintenance at Nuclear Power Plants," Revision 3 (77 FR 70846). However, the industry guidance that is endorsed is the same in both Regulatory Guides, and consequently, compliance with the endorsed industry guidance provides an acceptable method of implementing 10 CFR 50.65(a)(4).

their specified frequency, entry into a higher mode {or other specified condition) is not allowed by SR 4.0.4. The current Turkey Point 3 and 4 TS LCO 3.0.4 reads:

Entry into an OPERATIONAL MODE or other specified condition shall not be made when the conditions for the Limiting Conditions for Operation are not met and the associated ACTION requires a shutdown if they are not met within a specified time interval. Entry into an OPERATIONAL MODE or specified condition may be made in accordance with ACTION requirements when conformance to them permits continued operation of the facility for an unlimited period of time. This provision shall not prevent passage through or to OPERATIONAL MODES as required to comply with ACTION requirements.

Exceptions to these requirements are stated in the individual specifications.

The licensee's proposed revision to LCO 3.0.4 will read:

When an LCO is not met, entry into a MODE or other specified condition in the Applicability shall only be made:

a. When the associated ACTIONS to be entered permit continued operation in the MODE or other specified condition in the Applicability for an unlimited period of time;
b. After performance of a risk assessment addressing inoperable systems and components, consideration of the results, determination of the acceptability of entering the MODE or other specified condition in the Applicability, and establishment of risk management actions, if appropriate; exceptions to this Specification are stated in the individual Specifications, or
c. When an allowance is stated in the individual value, parameter, or other Specification.

This Specification shall not prevent changes in MODES or other specified conditions in the Applicability that are required to comply with ACTIONS or that are part of a shutdown of the unit."

The Turkey Point 3 and 4 current TS SR 4.0.4 reads:

Entry into an OPERATIONAL MODE or other specified condition shall not be made unless the Surveillance Requirement{s) associated with a Limiting Condition for Operation has been performed within the stated surveillance interval or as otherwise specified. This provision shall not prevent passage through or to OPERATIONAL MODES as required to comply with ACTION requirements.

The licensee's proposed revision to SR 4.04 will read:

Entry into a MODE or other specified condition in the Applicability of an LCO shall only be made when the LCO's Surveillances have been met within their specified frequency, except as provided by Specification 4.0.3. When an LCO is not met due to Surveillances not having been met, entry into a MODE or

other specified condition in the Applicability shall only be made in accordance with Specification 3.0.4.

This provision shall not prevent entry into MODES or other specified conditions in the Applicability that are required to comply with ACTIONS or that are part of a shutdown of the unit.

The proposed LCO 3.0.4.a retains the current allowance for when the required actions allow indefinite operation. The proposed LCO 3.0.4.b allows entering modes or other specified conditions in the applicability except when higher-risk systems and components (listed in Section 3.1.1 ), for the mode being entered, are inoperable. When applying LCO 3.0.4.b, the decision for entering a higher mode or condition in the Applicability of the LCO will be made by plant management after the required risk assessment has been performed and requisite risk management actions established, through the program established to implement 10 CFR 50.65(a)(4). Entry into the modes or other specified conditions in the Applicability of the TS shall be for no more than the duration of the applicable required actions completion time, or until the LCO is met. The licensee has proposed to remove current notes in individual specifications that prohibit mode changes that are now encompassed by LCO 3.0.4.b. Similarly, the licensee has proposed to add notes that prohibit mode changes under LCO 3.0.4.b for higher-risk systems and components. The proposed LCO 3.0.4.b allowance can involve multiple components in a single LCO or in multiple LCOs; however, use of the LCO 3.0.4.b provisions are always contingent upon completion of a 10 CFR 50.65(a)(4)-based risk assessment.

The notes limiting the applicability, to Modes 1, 2, 3, and 4 of the current TS LCO 3.0.4 and SR 4.0.4 are holdovers from the Turkey Point 3 and 4 operating licenses. The notes limiting the applicability of LCO 3.0.4 and SR 4.0.4 are no longer needed and are removed consistent with approved TSTF-359, Revision 9. Consideration was originally given to adding notes to various TS, as defined by the tables of higher-risk systems, precluding entry into Modes 5 and 6 for pressurized-water reactors (PWRs). However, it was determined that the addition of notes in these cases is unnecessary the action statements require immediate completion times, which means that entry into the Mode or other specified condition in the Applicability is not allowed and the notes would be superfluous.

LCO 3.0.4 allowances related to values and parameters of TS are not typically addressed by LCO 3.0.4.b risk assessments, and are therefore addressed by a new LCO 3.0.4(c).

LCO 3.0.4(c) refers to allowances already in the TS and annotated in the individual TS.

LCO 3.0.4(c) also allows for entry into the modes or other specified conditions in the Applicability for TS for no more than the duration of the applicable required actions completion time or until the LCO is met or the unit is not within the applicability of the TS.

3.0 TECHNICAL EVALUATION

During the development of the current STS, improvements were made to LCO 3.0.4, such as clarifying its applicability with respect to plant shutdowns, cold shutdown mode and refueling mode. In addition, during the STS development, almost all the LCO with completion times greater than or equal to 30 days, and many LCO with completion times greater than or equal to 7 days, were given individual LCO 3.0.4 exceptions. During some conversions to the STS, individual plants provided acceptable justifications for other LCO 3.0.4 exceptions. All of these specific LCO 3.0.4 exceptions allow entry into a mode or other specified condition in the TS applicability while relying on the TS required actions and associated completion times. The change proposed by the licensee for Turkey Point 3 and 4 would provide standardization and

consistency to the use and application of LCO 3.0.4, both internal to and between each of the specifications, as well as with the STS. This proposed change will also ensure consistency through the utilization of appropriate levels of risk assessment of plant configurations for application of LCO 3.0.4. However, nothing in this safety evaluation should be interpreted as encouraging upward mode transition with inoperable equipment. Good practice should dictate that such transitions should normally be initiated only when all required equipment is operable and that mode transition with inoperable equipment should be the exception rather than the rule.

The current LCO 3.0.4.a allowances are retained in the proposal and do not represent a change in risk from the current situation. The LCO 3.0.4.b allowances apply to systems and components, and require a risk assessment prior to utilization to ensure an acceptable level of safety is maintained. The LCO 3.0.4(c) allowances apply to parameters and values that have been previously approved by the NRC in a plant's specific TS. The licensee provided in their TS Bases a discussion and list of each NRC approved LCO 3.0.4(c) specific value and parameter allowance. The bases of LCO 3.0.4 are revised to explain the new allowances and their utilization.

In its review of TSTF-359, the NRC staff did a generic qualitative assessment of the risk impact of the proposed change in LCO 3.0.4.b allowances by evaluating how licensee implementation of the proposed risk-informed approach is expected to meet the requirements of the applicable RGs. The NRC staff referred to the guidance provided in RG 1.174 and in RG 1.177. RG 1.177 provides the NRC staff's recommendations on using risk information to assess the impact of proposed changes to nuclear power plant TS on the risk associated with plant operation.

Although RG 1.177 does not specifically address the type of generic change in this proposal, the NRC staff considered the approach documented in RG 1.177 in evaluating the risk information provided in support the proposed changes in LCO 3.0.4.

The NRC staff's evaluation of how the implementation of the proposed risk-informed approach, used to justify LCO 3.0.4.b allowances, agrees with the objectives of the guidance outlined in RG 1.177 is discussed in Section 3.1. Oversight of the risk-informed approach associated with the LCO 3.0.4.b allowances is discussed in Section 3.2 of this safety evaluation.

3.1 Evaluation of Risk Management Both the temporary and cumulative risk of the proposed change is adequately limited. The temporary risk is limited by the exclusion of higher-risk systems and components, and completion time limits contained in TS (Section 3.1.1 of this safety evaluation). The cumulative risk is limited by the temporary risk limitations and by the expected low frequency of the proposed mode changes with inoperable equipment (Section 3.1.2 of this safety evaluation).

Adequate NRC oversight of the licensee's ability to use the LCO 3.0.4.b provisions under appropriate circumstances, that is, to identify risk-significant configurations when entering a higher mode or condition in the applicability of an LCO (Section 3.1.3 of this safety evaluation) is provided by NRC inspection of the licensee's implementation of 10 CFR 50.65(a)(4) as applied to the proposed change.

3.1.1 Temporary Risk Increases RG 1.177 proposes the incremental conditional core damage probability (ICCDP) and the incremental conditional large early release probability (ICLERP) as appropriate measures of the increase in probability of core damage and large early release, respectively, during the period of implementation of a proposed TS change. In addition, RG 1.177 stresses the need to preclude potentially high-risk configurations introduced by the proposed change. The ICCDP associated

with any specified plant condition, such as the condition introduced by entering a higher mode with plant equipment inoperable, is expressed by the following equation:

ICCDP =flR d = (R1 - Ro) d (1) where:

6R = the conditional risk increase, in terms of core damage frequency (CDF), caused by the specified condition d = the duration of the specified plant condition R1 = the plant CDF with the specified condition permanently present Ro = the plant CDF without the specified condition The same expression can be used for ICLERP by substituting the measure of risk, that is, large early release frequency (LERF) for CDF. The magnitude of the ICCDP and ICLERP values associated with plant conditions applicable to LCO 3.0.4.b allowances can be managed by controlling the conditional risk increase, 6R (in terms of both CDF and LERF) and the duration, d, of such conditions. The following sections discuss how the key elements of the proposed risk-informed approach, used to justify LCO 3.0.4.b allowances, are expected to limit flR and d and, thus, prevent any significant temporary risk increases.

Identification of Risk-Important TS Systems and Components A major element that limits the risk of the proposed mode change flexibility is the exclusion of certain systems and associated LCO for the mode change allowance. TS allow operation in Mode 1 (power operation) with specified levels of inoperability for specified times. This provides a benchmark of currently acceptable risk against which to measure any incremental risk inherent in the proposed LCO 3.0.4.b. If a system inoperability accrues risk at a higher rate in one or more of the transition modes than it would in Mode 1, then an upward transition into that mode should not be allowed without demonstration of a high degree of experience and sophistication in risk management. However, the risk management process evaluated in Section 3.1.3 is adequate if higher-risk systems/components are excluded from the scope of LCO 3.0.4.b.

The importance of most TS systems in mitigating accidents increases as power increases.

However, some TS systems are relatively more important during lower power and shutdown operations, because:

  • Certain events are peculiar to modes of plant operation other than power operation,
  • Certain events are more probable at modes of plant operation other than power operation, and
  • Some modes of plant operation have less mitigation system capability than power operation.

The risk information submitted in support of the proposed changes to LCO 3.0.4 and SR 4.0.4 in TSTF-359 included qualitative risk assessments performed by each owners group to identify

higher risk systems and components at the various modes of operation, including transitions between modes, as the plant moves upward from the refueling mode of operation toward power operation. The owners groups' generic qualitative risk assessments are included as attachments to TSTF-359, Revision 9. Each of the owners groups' generic qualitative risk assessments discuss the technical approach used and the systems/components subsequently determined to be of higher risk significance; the systems/components not to be granted the LCO 3.0.4 allowances for the various modes are listed. The Westinghouse owners groups' (WOG) generic qualitative risk assessments:

  • 'WOG Qualitative Risk Assessment Supporting Increased Flexibility in MODE Restraints."

Following interactions with the NRG staff, all owners groups used the same systematic approach in their qualitative risk assessments to identify the higher-risk systems in the STS, consisting of the following steps:

  • Identification of plant conditions (i.e., plant parameters and availability of key mitigation systems) associated with changes in plant modes while returning to power,
  • Identification of key activiti.es that have the potential to impact risk and which are in progress during transitions between modes while the plant is returning t9 power,
  • Identification of applicable accident initiating events for each mode or other specified condition in the applicability, and
  • Identification of the higher-risk systems and components by combining the information in the first three steps (qualitative risk assessment)

The risk assessments properly used the results and insights from previous deterministic and probabilistic studies to systematically search for plant conditions in which certain key plant components are more important in mitigating accidents than during operation at power (Mode 1). This search was systematic, taking the following factors into account for the various stages of returning the plant to power:

  • The status of accident mitigation and normally operating systems
  • The key activities that are in progress during transitions between modes which have the potential to impact risk (e.g., the transfer from auxiliary to main feedwater at some PWR plants when Mode 1 is entered)
  • Design and operational differences among plants or groups of plants The following systems and components were identified by the PWR owners group as higher-risk systems and components, when the plant is entering a new mode.

Westinghouse Owners Group (WOG) Plants System Entering Mode Emergency Diesel Generators (EDGs) 5,4,3,2, 1 Auxiliary Feedwater (AFW) System (for plants depending on AFW for startup) 4,3,2, 1 High Head Safety Injection System 4 Cold Overpressure Protection System 5,4 Residual Heat Removal (RHR) System 5 If a licensee identifies a higher-risk system for only some of the modes of applicability, the TS for that system would be modified by a note that reads, for example, "LCO 3.0.4.b is not applicable when entering MODE 1 from MODE 2." Systems identified as higher risk for Modes 5 and 6 for PWRs, are also excluded from transitioning up to the mode of higher risk, and as previously discussed, notes for those transitions are superfluous. In addition, mode transitions for Modes 5 and 6 for PWRs, will be addressed by administrative controls.

In summary, the NRC staff's review of the owners groups qualitative risk assessments finds that they are of adequate quality to support the application (i.e., they identify the higher-risk systems and components) associated with entering higher modes of plant operation with equipment inoperable while returning to power.

The licensee proposes to modify the LCO 3.0.4.b exclusion for AFW in TSTF-359 from "LCO 3.0.4b not applicable when entering MODE 1" to "LCO 3.0.4.b is not applicable to the required auxiliary feedwater trains when entering MODE 1." The note will prohibit a transition to MODE 1 with less than two independent AFW trains operable. The change will permit a transition to MODE 1 in accordance with LCO 3.0.4.b with a single AFW pump or steam supply flow path inoperable provided two independent AFW trains are operable.

The Turkey Point 3 and 4 AFW system includes three steam turbine-driven pumps such that each pump supplies feedwater to either Unit 3 or 4, with any single pump supplying the total feedwater requirement of either unit. Two pumps are normally aligned to one AFW train, and the third pump is normally aligned to the other AFW train. TS 3.7.1.2, Auxiliary Feedwater, requires that two independent auxiliary feedwater trains including three steam supply flow paths, three pumps, and associated discharge water flow paths shall be operable. The LCO requires a third steam supply flow path aligned to one of the AFW trains and a third AFW pump that can be aligned to either train to restore operability in the event a train-associated AFW pump becomes inoperable.

In addition, two non-safety grade standby steam generator feedwater pumps (SSGFP) are provided. The SSGFPs are normally used to supply feedwater during startup, shutdown, and hot standby conditions. One pump is motor-driven and the other pump is diesel engine-driven.

While the AFW system is the normal supply of feedwater in the event of a loss of offsite power, feedwater can also be supplied by the diesel engine-driven SSGFP. The configuration of Turkey Point 3 and 4 AFW system and SSGFP would allow the mode change to proceed with a single AFW pump or steam supply inoperable. Prohibiting Mode 1 entry without two operable

AFW trains is appropriate while entry into Mode 1 with two operable trains provides sufficient AFW capability to mitigate a loss of feedwater during startup activities in Mode 1. LCO 3.0.4.b continues to require a risk assessment addressing inoperable systems and components. The NRC staff agrees with the modification of LCO 3.0.4.b to prohibit transition to MODE 1 in accordance with LCO 3.0.4.b, with a single AFW pump or steam supply flow path inoperable.

Limited Time in TS Required Actions Any temporary risk increase will be limited by, among other factors, duration constraints imposed by the TS completion times of the inoperable systems. For the systems and components that are not higher risk, any temporary risk increase associated with the proposed allowance will be smaller than what is considered acceptable when the same systems and components are inoperable at power. This is due to the fact that completion times associated with the majority of TS systems and components were developed for power operation and pose a smaller plant risk for action statement entries initiated or occurring at lower modes of operation as compared to power operation.

The LCO 3.0.4.b allowance will be used only when the licensee determines that there is a high likelihood that the LCO will be satisfied following the mode change. This will minimize the likelihood of additional temporary risk increases associated with the need to exit a mode due to failure to restore the unavailable equipment within the completion time. In most cases, licensees will enter into a higher mode with the intent to move up to Mode 1 (power operation).

As discussed in Section 3.2, the revised reactor oversight process monitors unplanned power changes as a performance indicator. The reactor oversight process, thus, discourages licensees from entering a mode or other specified condition in the applicability of an LCO, and moving up in power, when there is a likelihood that the mode would have to be subsequently exited due to failure to restore the unavailable equipment within the completion time. Another disincentive for licensees to enter a higher mode when an LCO is not met is related to reporting requirements. It clearly states in 10 CFR 50.72 and 50.73 that a report is required when a nuclear plant shutdown or mode change is required by TS. The NRC's oversight program will provide the framework for inspectors and other staff to follow the history at a specific plant of entering higher modes while an LCO is not met, and use such information in assessing the licensee's actions and performance.

3.1.2 Cumulative Risk Increases The cumulative risk impact of the change to allow the plant to enter a higher mode of operation with one or more safety-related components unavailable (as proposed here), is measured by the average yearly risk increase associated with the change. In general, this cumulative risk increase is assessed in terms of both CDF and LERF (i.e., ~CDF and ~LEAF, respectively).

The increase in CDF due to the proposed change is expressed by the following equation, which integrates the risk impact from all expected specified conditions (i.e., all expected plant conditions caused by mode changes with various TS systems and components unavailable).

(2)

Where

~CDFi = the CDF increase due to specified condition i ICCDPi = the ICCDP associated with specified condition i

fi = the average yearly frequency of occurrence of specified condition i A similar expression can be used for ~LEAF by substituting the measure of risk {i.e., LEAF for CDF). The magnitude of the ~CDF and ~LEAF values associated with plant conditions applicable to LCO 3.0.4.b allowances can be managed by controlling the temporary risk increases, in terms of both CDF and LEAF {i.e., ICCDP and ICLERP), and the frequency {f),

of each of such conditions. In addition to the points made in the previous section regarding temporary risk increases, the following points put into perspective how the key elements of the proposed risk-informed approach, used to justify an LCO 3.0.4.b allowance, are expected to prevent significant cumulative risk increases by limiting the frequency of its use:

  • The frequency of risk-significant conditions will be limited by not providing the LCO 3.0.4.b allowances to the higher risk systems and components.
  • The frequency of risk-significant conditions will be limited by the requirement to assess the likelihood that the LCO will be satisfied following the mode change.
  • The frequency of risk-significant conditions is limited by the fact that such conditions can occur only when the plant is returning to power following shutdown, that is, during a small fraction of time per year {data over the past 5 years indicate that the plants are averaging 2.1 startups per year).

The addition of the proposed LCO 3.0.4.b allowances to the plant maintenance activities is not expected to change the plant's average {cumulative) risk significantly.

3.1.3 Risk Assessment and Risk Management of Mode Changes With all safety systems and components operable, a plant can transition up in mode to power operation. With one or more system{s) or component{s) inoperable, this change permits a plant to transition up in mode to power operation if the inoperable system{s) or component{s) are not in the pre-analyzed higher risk category, a 10 CFR 50.65{a){4)-based risk assessment is performed prior to the mode transition, and the requisite risk management actions are taken.

The proposed TS Bases state that when an LCO is not met, LCO 3.0.4 also allows entering MODES or other specified conditions in the Applicability following assessment of the risk impact and determination that the impact can be managed. The risk assessment may use quantitative, qualitative, or blended approaches, and the risk assessment will be conducted using the plant program, procedures, and criteria in place to implement 10 CFR 50.65{a){4), which requires that risk impacts of maintenance activities to be assessed and managed.

It should be noted that the risk assessment, for the purposes of LCO 3.0.4.b, must take into account all inoperable TS equipment regardless of whether the equipment is included in the licensee's normal 10 CFR 50.65{a){4) risk assessment scope. The risk assessments will be conducted using the procedures and guidance endorsed by RG 1.160. The results of the risk assessment shall be considered in determining the acceptability of entering the MODE or other specified condition in the Applicability, and any corresponding risk management actions. A risk assessment and establishment of risk management actions, as appropriate, are required for determination of acceptable risk for entering MODE or other specified conditions in the Applicability when an LCO is not met. Elements of acceptable risk assessment and risk management actions are included in Section 11 of NUMARC 93-01, "Assessment of Risk Resulting from Performance of Maintenance Activities" {ADAMS Accession No. ML11116A198),

as endorsed by RG 1.160, which addresses general guidance for conduct of the risk assessment, gives quantitative and qualitative guidelines for establishing risk management actions, and provides example risk management actions. These risk management actions include actions to plan and conduct other activities in a manner that controls overall risk, actions to increase risk awareness by shift and management personnel, actions to reduce the duration of the conditions, actions to minimize the magnitude of risk increases (establishment of backup success paths or compensatory measures), and determination that the proposed MODE change is acceptable.

The guidance references state that a licensee's risk assessment process should be sufficiently robust and comprehensive to assess risk associated with maintenance activities during power operation, low power, and shutdown conditions (all modes of operation), including changes in plant conditions. NUMARC 93-01 states that the risk assessment should include consideration of: the degree of redundancy available for performance of the safety function(s) served by the out-of-service equipment; the duration of the out-of-service condition; component and system dependencies that are affected; the risk impact of performing the maintenance during shutdown versus at power; and, the impact of mode transition risk. For power operation, key plant safety functions are those that ensure the integrity of the reactor coolant pressure boundary, ensure the capability to shut down and maintain the reactor in safe shutdown condition, and ensure the capability to prevent or mitigate the consequences of accidents that could result in potentially significant offsite exposures.

While the inoperabilities permitted by the completion times of TS required actions take into consideration the safety significance and redundancy of the system or components within the scope of an LCO, the completion times generally do not address or consider concurrent system or component inoperabilities in multiple LCOs. Therefore, the performance of the 10 CFR 50.65(a)(4) risk assessment that looks at the entire plant configuration is essential (and required) prior to changing the mode. The 10 CFR 50.65(a)(4)-based risk assessment will be used to confirm (or reject) the appropriateness of transitioning up in mode given the actual status of plant safety equipment.

The risk impact on the plant condition of invoking an LCO 3.0.4.b allowance will be assessed and managed through the program established to implement 10 CFR 50.65{a){4). This program is consistent with RG 1.177 and RG 1.174 in its approach. The implementation guidance for paragraph (a)(4) of the Maintenance Rule addresses controlling temporary risk increases resulting from maintenance activities. This guidance, consistent with guidance in RG 1.177, establishes action thresholds based on qualitative and quantitative considerations and risk management actions. Significant temporary risk increases following an LCO 3.0.4.b allowance are unlikely to occur unless:

  • High-risk configurations are allowed (e.g., certain combinations of multiple component outages), or
  • Risk management of plant operation activities is inadequate.

The requirements associated with the proposed change are established to ensure that such conditions will not occur.

The thresholds of the cumulative (aggregate) risk impacts, assessed pursuant to 10 CFR 50.65{a)(4) and the associated implementation guidance, are based on the permanent change guidelines in NRC RG 1.174. Therefore, licensees will manage the risk exercising LCO 3.0.4 in

conjunction with the risk from other concurrent plant activities to ensure that any increase, in terms of GDF and LERF will be small and consistent with the Commission's Safety Goal Policy Statement.

3.2 Oversight The reactor oversight process (ROP) provides a means for assessing the licensee's performance in the application of the proposed mode change flexibility. The adequacy of the licensee's assessment and management of maintenance-related risk is addressed by existing inspection programs and guidance for 10 CFR 50.65(a)(4). Although the current versions of that guidance do not specifically address application of the licensee's (a)(4) program to support risk-informed TS, it is expected that, in most cases, risk assessment and management associated with risk-informed TS would be required by (a)(4) anyway because maintenance activities will be involved.

Adoption of the proposed change will make failure to assess and manage the risk of an upward mode change with inoperable equipment covered by TS, prior to commencing such a mode change, a violation of TS. Further, as explained above in general, under most foreseeable circumstances, such a change in configuration would also require a risk assessment under 10 CFR 50.65(a)(4). Inoperable systems or components will necessitate maintenance to restore them to operability, and hence a 10 CFR 50.65(a)(4) risk assessment would be performed prior to the performance of those maintenance actions (except for immediate plant stabilization and restoration actions if necessary). Further, before altering the plant's configuration, including plant configuration changes associated with mode changes, the licensee must update the existing (a)(4) risk assessment to reflect those changes.

The Federal Register Notice issuing a revision to the Maintenance Rule, 10 CFR 50.65 (64 FR 38553), along with NRG Inspection Procedure 71111.13 and NUMARC 93-01, Section 11, dated February 22, 2000, "Assessment of Risk Resulting from Performance of Maintenance Activities," all indicate that to determine the safety impact of a change in plant conditions during maintenance, a risk assessment must be performed before changing plant conditions. The bases for the proposed TS change mandate that the risk assessment and management of upward mode changes will be conducted under the licensee's program and process for meeting 10 CFR 50.65(a)(4). Oversight of licensee performance in assessing and managing the risk of plant maintenance activities is conducted principally by inspection in accordance with Reactor Oversight Program Baseline Inspection Procedure 71111.13.

Supplemental Inspection Procedure 62709, "Configuration Risk Assessment and Risk Management Process," is utilized to evaluate the licensee's process, when necessary.

The ROP is described in overview in NUREG-1649, Rev. 6, "Reactor Oversight Process," and in detail in the NRG Inspection Manual. Inspection Procedure 71111.13 requires verification of performance of risk assessments when they are required by 10 CFR 50.65(a)(4) and in accordance with licensee procedures. The procedure also requires verification of the adequacy of those risk assessments and verification of effective implementation of licensee-prescribed risk management actions. The rule itself requires such assessment and management of risk prior to maintenance activities, including preventive maintenance, surveillance, and testing (and promptly for emergent work) during all modes of plant operation. The guidance documents for both industry implementation of (a)(4) and NRG oversight of that implementation indicate that changes in plant configuration (which would include mode changes) in support of maintenance activities must be taken into account in the risk assessment and management process.

Revisions to NRC inspection guidance and licensee implementation procedures will be needed to address oversight of risk assessment and management required by TS in support of mode changes that are not already required under the circumstances by (a)(4). This consideration provides performance-based regulatory oversight of the use of the proposed flexibility, and a disincentive to use the flexibility without the requisite care in planning.

In addition, the NRC staff developed the significance determination process guidance for use in assessing inspection findings related to 10 CFR 50.65(a)(4). This guidance was issued in draft for comment and became final during August 2008. The ROP considers inspection findings and performance indicators in evaluating licensee ability to operate safely. The significance determination process is used to determine the significance of inspection findings related to licensee assessment and management of the risk associated with performing maintenance activities under all plant operating or shutdown conditions. Unplanned reactor scrams and unplanned power changes are two of the Reactor Safety Performance Indicators that the ROP utilizes to assess licensee performance and inform the public. The ROP will provide a disincentive to entering into power operation (Mode 1) when there is a" significant likelihood that the mode would have to be subsequently exited due to failure to restore the unavailable equipment within the completion time.

3.3 Summary The licensee submitted a proposed TS change to allow entry into a higher mode of operation, or other specified condition in the TS Applicability, while relying on the TS conditions, and associated required actions and completion times, provided a risk assessment is performed to confirm the acceptability of that action. The proposal revises Turkey Point 3 and 4 LCO 3.0.4 and SR 4.0.4, and their application to the TS. New paragraphs (a), (b), and (c) are proposed for LCO 3.0.4.

The proposed LCO 3.0.4.a retains the current allowance, permitting the mode change when the TS required actions allow indefinite operation.

Proposed LCO 3.0.4.b is the change to allow entry into a higher mode of operation, or other specified condition in the TS Applicability, while relying on the TS conditions and associated required actions and completion times, provided a risk assessment is performed to confirm the acceptability of that action for the existing plant configuration. The NRC staff review finds that the process proposed by the licensee for assessing and managing risk during the implementation of the proposed LCO 3.0.4.b allowances meets Commission guidance for TS changes. Key elements of this process are listed below.

  • A risk assessment shall be performed before any LCO 3.0.4.b allowance is invoked.
  • The risk impact on the plant condition when invoking an LCO 3.0.4.b allowance will be assessed and managed through the program established to implement 10 CFR 50.65(a)(4) and the associated guidance in RG 1.160. Allowing entry into a higher mode or condition in the Applicability of an LCO after a 10 CFR 50.65(a)(4) based risk assessment and appropriate risk management actions are taken for the existing plant configuration will ensure that plant safety is maintained.
  • The LCO 3.0.4.b allowance will be used only when the licensee determines that there is a high likelihood that the LCO will be satisfied within the required action's completion time.
  • TS systems and components that may be of higher risk during mode changes have been identified generically by each owners' group for each plant operational mode or condition. Licensees will identify such plant-specific systems and components in the individual plant TS. The proposed LCO 3.0.4.b allowance does not apply to these systems and components for the mode or condition in the applicability of an LCO at which they are of higher risk.
  • In adopting LCO 3.0.4.b, the licensee will ensure that plant procedures in place to implement 10 CFR 50.65(a){4) address the situation where entering a mode or other specified condition in the applicability is contemplated with plant equipment inoperable.

Such plant procedures will follow the guidance endorsed by NRC RG 1.160.

The NRC's reactor oversight process provides the framework for inspectors and other NRC staff to oversee the implementation of 10 CFR 50.65(a){4) requirements at a specific plant and assess the licensee's actions and performance.

The LCO 3.0.4.b allowance does not apply to values and parameters of the TS that have their own respective LCO (e.g., Reactor Coolant System Specific Activity), but instead those values and parameters are addressed by LCO 3.0.4(c). The TS values and parameters for which mode transition allowances apply, will have a note that states LCO 3.0.4(c) is applicable.

The objective of the proposed change is to provide additional operational flexibility without compromising plant safety.

The licensee has a bases control program in Turkey Point 3 and 4 TS 6.8.4 which is consistent with the bases control program described in the STS for Westinghouse plants, NUREG-1431, Revision 4. The licensee committed to implement the TS Bases change for LCO 3.0.4 and SR 4.0.4 concurrent with the license amendment. The NRC staff agrees that the TS Bases Control Program is the appropriate process for updating the affected TS Bases pages.

The licensee's proposed changes are acceptable because the adopted key elements; requires the licensee to assess and manage risk; and they are consistent with approved TSTF-359 and the Commission's regulations.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the NRC staff notified the State of Florida official (Ms. Cynthia Becker, M.P.H., Chief of the Bureau of Radiation Control, Florida Department of Health) on January 30, 2018 (ADAMS Accession No. ML18033A015), of the proposed issuance of the amendments. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendments change a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and change surveillance requirements. The NRC staff has determined that the amendments involve no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding, which was published in the Federal Register on September 12, 2017 (82 FR 42850), that the

amendments involve no significant hazards consideration, and there has been no public comment on such finding. Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.

6.0 CONCLUSION

The Commission has concluded, based on the aforementioned considerations, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) there is reasonable assurance that such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
