Dear Ms. Gayheart:

The U.S. Nuclear Regulatory Commission (NRC, the Commission) has issued the enclosed Amendment No. 290 to Renewed Facility Operating License No. DPR-57 and Amendment No. 235 to Renewed Facility Operating License No. NPF-5 for the Edwin I. Hatch Nuclear Plant, Unit Nos. 1 and 2 (HNP), respectively. The amendments consist of changes to the Technical Specifications (TSs) in response to your application dated April 20, 2017, as supplemented by letters dated September 14, 2017, and February 19 and May 1, 2018.

The amendments replace the existing requirements in several TSs related to operations with a potential for draining the reactor vessel with revised TSs providing alternative requirements in new TS 3.5.2, "Reactor Pressure Vessel (RPV) Water Inventory Control," and associated changes. These alternative requirements ensure that Safety Limit 2.1.1.3, which requires RPV water level to be greater than the top of active fuel, will continue to be met.

C. A. Gayheart A copy of the related Safety Evaluation is also enclosed. A Notice of Issuance will be included in the Commission's biweekly Federal Register notice.

Sincerely, Jl:~~~~ct Plant Licensing Branch 11-1 Manager Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-321 and 50-366

2. Penetration flow paths capable of being isolated by valves that will close automatically without offsite power prior to the RPV water level being equal to the TAF when actuated by RPV water level isolation instrumentation; or

3. Penetration flow paths with isolation devices that can be closed prior to the RPV water level being equal to the TAF by a dedicated operator trained in the task, who in continuous communication with the control room, is stationed at the controls, and is capable of closing the penetration flow path isolation device without offsite power.

c. The penetration flow paths required to be evaluated per paragraph b) are assumed to open instantaneously and are not subsequently isolated, and no water is assumed to be subsequently added to the RPV water inventory;

d. No additional draining events occur; and

e. Realistic cross-sectional areas and drain rates are used.

A bounding DRAIN TIME may be used in lieu of a calculated value.

1.0 INTRODUCTION

By application dated April 20, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17114A377) (Reference 1), as supplemented by letters dated September 14, 2017 (ADAMS Accession No. ML17257A375) (Reference 2), February 19, 2018 (ADAMS Accession No. ML18050A052) (Reference 3), and May 1, 2018 (ADAMS Accession No. ML18121A398) (Reference 4), Southern Nuclear Operating Company, Inc. (SNC, the licensee) requested to adopt Technical Specifications Task Force (TSTF) Traveler TSTF-542, Revision 2, "Reactor Pressure Vessel Water Inventory Control," which would change the Technical Specifications (TSs) for the Edwin I. Hatch Nuclear Plant (HNP), Unit Nos. 1 and 2. TSTF-542, Revision 2, was approved by the U.S. Nuclear Regulatory Commission (NRC) on December 20, 2016 (ADAMS Accession No. ML163438008) (Reference 5).

The proposed changes would replace existing TSs requirements associated with "operations with a potential for draining the reactor vessel," (OPDRVs) with revised TSs providing alternative requirements for Reactor Pressure Vessel (RPV) Water Inventory Control (WIC). These alternative requirements would ensure that Safety Limit 2.1.1.3 is met. HNP TS Section 2.0, "Safety Limits (SLs)," 2.1.1.3, states, "Reactor vessel water level shall be greater than the top of active irradiated fuel."

Additionally, a new definition, "DRAIN TIME," would be added to the HNP TSs, Section 1.1, "Definitions." DRAIN TIME would establish requirements for the licensee to make RPV water level inventory determinations and to calculate RPV water inventory drain rates for MODE 4 and 5 outage-related activities. Adequate licensee management of secondary containment requirements or mitigation of certain emergency core cooling system (ECCS) safety injection/spray systems during MODE 4 and 5 requires a properly calculated DRAIN TIME.

Enclosure 3

The licensee has proposed several variations from the TS changes described in the applicable parts of TSTF-542, Revision 2, as approved by the NRC in the safety evaluation for TSTF-542 (Reference 5). These are explained below in Section 2.2.5 and evaluated in Section 3.5 of this safety evaluation (SE).

The supplements dated September 14, 2017, and February 19 and May 1, 2018, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the NRC staff's original proposed no significant hazards consideration determination as published in the Federal Register on August 29, 2017 (82 FR 41071).

2.0 REGULATORY EVALUATION

2.1 System Description Boiling water reactor (BWR) RPVs have a number of penetrations located below the top of active fuel (TAF). These penetrations provide entry for control rods, recirculation flow, and shutdown cooling. Since these penetrations are below the TAF, this creates a potential to drain the reactor vessel water inventory and lose effective core cooling. The loss of water inventory and effective core cooling can potentially lead to fuel cladding failure and radioactive release.

During operation in Modes 1 (Power Operation - Reactor Mode Switch in Run), 2 (Startup -

Reactor Mode Switch in Refuel (with all reactor vessel head closure bolts fully tensioned) or Startup/Hot Standby), and 3 (Hot Shutdown - Reactor Mode Switch in Shutdown and average reactor coolant temperature> 212 degrees Fahrenheit (°F)), the TS for instrumentation and ECCS require operability of sufficient equipment to ensure large quantities of water will be injected into the vessel should level decrease below the preselected value. These requirements are designed to mitigate the effects of a loss-of-coolant accident (LOCA), but also provide protection for other accidents and transients that involve a water inventory loss.

During BWR operation in Mode 4 (Cold Shutdown - Reactor Mode Switch in Shutdown with all reactor vessel head closure bolts fully tensioned and average reactor coolant temperature

212 °F), and Mode 5 (Refueling - one or more reactor vessel head closure bolts less than fully tensioned and Reactor Mode Switch in Shutdown or Refuel), the pressures and temperatures that could cause a LOCA are not present. During certain phases of refueling (Mode 5), a large volume of water is available above the RPV (i.e., the RPV head is removed, the water level is

.:: 22 feet-1/8 inches over the top of the RPV flange, and the spent fuel storage pool gates are removed).

The large volume of water available in and above the RPV during much of the time when in Mode 5 provides time for operator detection and manual operator action to stop and mitigate an RPV draining event. However, at other times during a refueling outage, such as during Cold Shutdown (Mode 4) or Refueling (Mode 5), there may be a potential for significant drainage paths from certain outage activities, human error, and other events when it is more likely to have some normally available equipment, instrumentation, and systems inoperable due to maintenance and outage activities. There may not be as much time for operator action as compared to times when there are large volumes of water above the RPV.

In comparison to Modes 1, 2, and 3, with typical high temperatures and pressures (especially in Modes 1 and 2), Modes 4 and 5 generally do not have the high pressure and temperature considered necessary for a postulated LOCA due to a high energy pipe failure. Thus, while the

potential sudden loss of a large volume of water from a LOCA is not expected, operators still monitor BWR RPV water level to detect any decrease from potential significant or unexpected drainage paths. These potential drainage paths in Modes 4 and 5 generally would require less water replacement capability to maintain water above TAF.

To address the drain down potential during Modes 4 and 5, the current HNP TSs contain specifications that are applicable during an OPDRV, or require suspension of OPDRVs if certain equipment is inoperable. The term OPDRV is not specifically defined in the TS and historically has been subject to inconsistent application by licensees. The changes discussed in this SE are intended to resolve ambiguity by creating a new RPV WIC TS with associated equipment operability requirements, required actions, and surveillance requirements (SRs), and conforming deletion of references to OPDRVs throughout the TSs.

2.2 Proposed TS Changes Section 2.2.1 discusses the proposed addition of a new definition, "DRAIN TIME" (evaluated below in Section 3.1 ). Section 2.2.2 discusses the proposed revisions to TS 3.3, "Instrumentation," including the proposed revisions to TS 3.3.5.1, "Emergency Core Cooling System (ECCS) Instrumentation," the proposed addition of new TS 3.3.5.2, "Reactor Pressure Vessel (RPV) Water Inventory Control Instrumentation" (including Table 3.3.5.2-1 ), and the proposed renumbering of existing TS 3.3.5.2, "Reactor Core Isolation Cooling (RCIC) System Instrumentation" to 3.3.5.3.

Section 2.2.3 discusses the proposed revisions to TS 3.5, "Emergency Core Cooling System (ECCS) and Reactor Core Isolation Cooling (RCIC) System," including the proposed revisions to TS 3.5.2, "ECCS - Shutdown" (evaluated below in Section 3.3). Section 2.2.4 discusses the proposed deletion of existing TS references to OPDRVs (evaluated below in Section 3.6).

Section 2.2.5 discusses HNP plant-specific variations to TSTF-542, Revision 2 (evaluated below in Section 3.5).

2.2.1 Addition of DRAIN TIME Definition The following definition of "DRAIN TIME" would be added to Section 1.1, "Definitions":

The DRAIN TIME is the time it would take for the water inventory in and above the Reactor Pressure Vessel (RPV) to drain to the top of the active fuel (TAF) seated in the RPV assuming:

a. The water inventory above the TAF is divided by the limiting drain rate;

b. The limiting drain rate is the larger of the drain rate through a single penetration flow path with the highest flow rate, or the sum of the drain rates through multiple penetration flow paths susceptible to a common mode failure (e.g., seismic event, loss of normal power, single human error), for all penetration flow paths below the TAF except:

1. Penetration flow paths connected to an intact closed system, or isolated by manual or automatic valves that are locked, sealed, or otherwise secured in the closed position, blank flanges, or other devices that prevent flow of reactor coolant through the penetration flow paths;

2. Penetration flow paths capable of being isolated by valves that will close automatically without offsite power prior to the RPV water level being equal to the TAF when actuated by RPV water level isolation instrumentation; or

3. Penetration flow paths with isolation devices that can be closed prior to the RPV water level being equal to the TAF by a dedicated operator trained in the task, who is in continuous communication with the control room, is stationed at the controls, and is capable of closing the penetration flow path isolation device without offsite power.

c. The penetration flow paths required to be evaluated per paragraph b) are assumed to open instantaneously and are not subsequently isolated, and no water is assumed to be subsequently added to the RPV water inventory;

d. No additional draining events occur; and

e. Realistic cross-sectional areas and drain rates are used.

A bounding DRAIN TIME may be used in lieu of a calculated value.

2.2.2 TS 3.3, "Instrumentation" The following subsections describe the existing and proposed changes to the HNP TS, Section 3.3, "Instrumentation."

2.2.2.1 TS 3.3.5.1, "Emergency Core Cooling System (ECCS) Instrumentation" Proposed changes to TS 3.3.5.1 include the deletion of Note 1 in Required Actions 8.1, C.1, and E.1 which states: "Only applicable in Modes 1, 2 and 3."

For Table 3.3.5.1-1, the applicability in Modes 4 and 5 was proposed for deletion because the instrumentation requirements during shutdown would be consolidated into the new TS 3.3.5.2, "Reactor Pressure Vessel (RPV) Water Inventory Control Instrumentation." Modes 4 and 5 Applicability and associated requirements would be deleted for the following functions:

1. Core Spray System; (a) Reactor Vessel Water Level - Low Low Low, Level 1 (c) Reactor Steam Dome Pressure - Low (Injection Permissive)

(d) Core Spray Pump Discharge Flow-Low (Bypass)

2. Low Pressure Coolant Injection (LPCI) System; (a) Reactor Vessel Water Level - Low Low Low, Level 1 (c) Reactor Steam Dome Pressure - Low (Injection Permissive)

(f) Low Pressure Coolant Injection Pump Start - Time Delay Relay (Pumps A, B, C, and D)

(g) Low Pressure Coolant Injection Pump Discharge Flow - Low (Bypass)

Table 3.3.5.1-1 Footnote (a), which states, "When associated subsystem(s) are required to be OPERABLE," would be deleted. As a result, existing Footnotes (b), (c), and (d) would be renumbered (a), (b), and (c), respectively.

2.2.2.2 New TS 3.3.5.2, "Reactor Pressure Vessel (RPV) Water Inventory Control Instrumentation" The proposed new TS 3.3.5.2 would contain functions that are comprised of requirements moved from TSs 3.3.5.1 and 3.3.6.1, as well as new requirements. The proposed new TS 3.3.5.2 is shown below:

The completion time for both HNP and the Standard Technical Specifications (STS) state, "1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months from discovery of loss of initiation capability for feature(s) in both divisions."

2.2.5.2 Variation 2, CS and LPCI Flow Transmitter The HNP core spray (CS) and low pressure coolant injection (LPCI) subsystems have one flow transmitter per ECCS subsystem to detect the associated subsystems' flow rates, whereas the STS assume one flow transmitter per ECCS pump to detect the associated subsystems' flow rates. Each HNP CS subsystem has one CS pump, and each HNP LPCI subsystem has two RHR pumps. The licensee proposes to maintain the one channel per subsystem requirement for new Table 3.3.5.2-1. The licensee stated that, although for the CS subsystem this deviation of "1 per subsystem" versus "1 per pump" is editorial, keeping "1 per subsystem" will maintain consistency with the current language.

2.2.5.3 Variation 3, TS Table 3.3.5.2-1 Footnote The licensee is proposing to add a note to TS Table 3.3.5.2-1 to clarify the intent of allowing credit for an OPERABLE LPCI subsystem when it is aligned and operating in the decay heat removal mode of RHR. The licensee states that this is appropriate since the associated RHR pump minimum flow valve (while operating in the decay heat removal mode) is closed and deactivated to prevent inadvertent vessel drain down events. Because the minimum flow valve is closed and deactivated, the associated TS Table 3.3.5.2-1 Function 2.b would not be required to be OPERABLE. Without the note, TS 3.3.5.2 Condition D would require that the associated RHR pump be declared inoperable, which would be contrary to the intent of the SR 3.5.2.4 (new SR 3.5.2.5) Note which allows the LPCI subsystem to be OPERABLE when aligned for decay heat removal.

2.2.5.4 Variation 4, Manual Initiation Logic The HNP TS do not include a manual initiation logic function for the CS or LPCI subsystems.

Considering the logic design, there is not a single switch that will start all subsystems of the associated ECCS system as is assumed in the STS. HNP does, however, have the capability to manually start the ECCS pumps individually. Since the manual initiation logic function does not exist at HNP, manual initiation functions for LPCI and CS are not proposed to be included in TS Table 3.3.5.2-1. Additionally, since the manual initiation functions are not proposed to be included in TS Table 3.3.5.2-1, the associated Logic System Functional Test would likewise not be required for TS 3.3.5.2; therefore, TS 3.3.5.2 as proposed for HNP would not include a Logic System Functional Test surveillance requirement.

As an alternative, the licensee proposes that TS 3.5.2 include an SR to verify that the HNP LPCI and CS subsystems can be manually operated through the manipulation of subsystem components from the Main Control Room. Proposed SR 3.5.2.8 would state:

"Verify the required ECCS injection/spray subsystem can be manually operated."

The licensee states that the manual operations of the LPCI and CS subsystems for the control of reactor cavity or RPV inventory are relatively simple evolutions and involve the manipulation of a small number of components. These subsystem alignments can be performed by licensed operators from the Main Control Room as described in HNP site procedures.

2.2.5.5 Variation 5, LPCI Realignment The STS Note on LCO 3.5.2 regarding realignment to the LPCI mode is located in HNP's SR 3.5.2.4 (new SR 3.5.2.5).

2.2.5.6 Variation 6, TS 3.6.1.3 Condition F HNP TS 3.6.1.3 Condition F (which corresponds to STS Condition H) does not contain the phrase "or during operations with a potential for draining the reactor vessel (OPDRVs)." This phrase is deleted from the STS per TSTF-542. Since OPDRVs are only performed in MODE 4 or MODE 5, this phrase that was contained in the STS was unnecessary.

2.2.5.7 Variation 7, Inverters HNP does not have an "Inverters - Operating" or an "Inverters - Shutdown" TS. As stated in the HNP improved TS Conversion, "Inverters, as utilized in the NUREG-1433 STS [References 7 and 8) (i.e., inverters that power many required systems and that are required to be powered by the DC sources to meet accident analysis assumptions), do not exist in the HNP. As such, NUREG-1433 LCO 3.8.7 and LCO 3.8.8, their associated Bases, and all references to them have been deleted. The LCOs that follow have been renumbered to reflect this deletion. The only inverters that need to be powered from DC sources are the LPCI inverters, which only provide power to the LPCI subsystems. These two inverters are covered by an SR in NUREG[-1433) LCO 3.5.1 (ECCS) since they only impact the LPCI subsystems."

2.2.5.8 Variation 8, Surveillance Frequency Control Program The HNP TSs contain a Surveillance Frequency Control Program (SFCP). Therefore, the Surveillance Requirement Frequencies for Specifications 3.3.5.2 and 3.5.2 are "In accordance with the Surveillance Frequency Control Program." HNP is adopting the recommended frequencies in TSTF-542 (within the SFCP), except that the SR 3.3.5.2.2 frequency to perform CHANNEL FUNCTIONAL TEST will be "92 days on an AL TERNATE TEST BASIS."

2.2.5.9 Variation 9, Table 3.3.5.2-1 on Applicability of ECCS Functions In accordance with TSTF-542, TS Table 3.3.5.2-1, Function 1.a (Core Spray System, Reactor Steam Dome Pressure - Low (Injection Permissive)), and Function 2.a (Low Pressure Coolant Injection (LPCI), Reactor Steam Dome Pressure - Low (Injection Permissive)) are required in Modes 4 and 5. Prior to TSTF-542 , the analogous Functions 1.c and 2.c in HNP TS Table 3.3.5.1-1 had a Mode 4 and 5 applicability modified by a footnote specifying that these functions were only required when the associated ECCS subsystem(s) were required to be operable per LCO 3.5.2, "ECCS - Shutdown." The footnote was inadvertently omitted from Table 3.3.5.2-1, Functions 1.a and 2.a in TSTF-542. The licensee proposed a variation to affix Footnote (a) (i.e., "Associated with an ECCS subsystem required to be OPERABLE by LCO 3.5.2, 'Reactor Pressure Vessel Water Inventory Control"') to TS Table 3.3.5.2-1 to correct the omission.

2.3 Applicable Regulatory Requirements The regulation at Title 10 of the Code of Federal Regulations (10 CFR), Section 50.36(a)(1 ),

requires an applicant for an operating license to include in the application proposed TSs in accordance with the requirements of 10 CFR 50.36. The applicant must also include in the application a "summary statement of the bases or reasons for such specifications, other than those covering administrative controls." However, per 10 CFR 50.36(a)(1 ), these TS bases "shall not become part of the technical specifications."

As required by 10 CFR 50.36(c)(1 )(i)(a), TSs will include items in the following categories:

(1) Safety limits, limiting safety system settings, and limiting control settings.

(i)(A) Safety limits for nuclear reactors are limits upon important process variables that are found to be necessary to reasonably protect the integrity of certain of the physical barriers that guard against the uncontrolled release of radioactivity. If any safety limit is exceeded, the reactor must be shut down. The licensee shall notify the Commission, review the matter, and record the results of the review, including the cause of the condition and the basis for corrective action taken to preclude recurrence. Operation must not be resumed until authorized by the Commission.

As required by 10 CFR 50.36(c)(2)(i), the TSs will include LCOs, which are the lowest functional capability or performance levels of equipment required for safe operation of the facility. Per 10 CFR 50.36(c)(2)(i), when an LCO of a nuclear reactor is not met, the licensee shall shut down the reactor or follow any remedial action permitted by the TSs until the condition can be met.

The regulation at 10 CFR 50.36(c)(2)(ii) requires licensees to establish TS LCOs for items meeting one or more of the listed criteria. Specifically, Criterion 4, "A structure, system, or component which operating experience or probabilistic risk assessment has shown to be significant to public health and safety," supports the establishment of LCOs for RPV WIC due to insights gained via operating experience.

The regulation at 10 CFR 50.36(c)(3) requires TSs to include items in the category of SRs, which are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the LCOs will be met.

Pursuant to 10 CFR 50.90, whenever a holder of an operating license desires to amend the license, application for an amendment must be filed with the Commission fully describing the changes desired, and following as far as applicable, the form prescribed for original applications. The technical information to be included in an application for an operating license is governed in particular by 10 CFR 50.34(b).

As described in 10 CFR 50.92(a), in determining whether an amendment to a license will be issued to the applicant, the Commission will be guided by the considerations which govern the issuance of initial licenses to the extent applicable and appropriate. The general considerations that guide the Commission include, as stated in 10 CFR 50.40(a), how the TSs provide reasonable assurance that the health and safety of the public will not be endangered. Also, to issue an operating license, of which TSs are a part, the Commission must make the findings of 10 CFR 50.57, including finding the 10 CFR 50.57(a)(3)(i) finding that there is reasonable assurance that the activities authorized by the operating license can be conducted without endangering the health and safety of the public.

As part of the regulatory standardization effort, the NRC staff has prepared STS for each of the light-water reactor nuclear designs. NUREG-1433, Volumes 1 and 2, Revision 4 (References 7 and 8), contains the STS for BWR/4 plants. The approved changes to the STS in TSTF-542 will be incorporated into future revisions of NUREG-1433.

The NRC staff's guidance for review of TSs is in Chapter 16, Technical Specifications, of NUREG-0800, Revision 3, "Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants" (SRP), dated March 2010 (ADAMS Accession No. ML100351425)

(Reference 6).

2.3.1 Applicable Regulatory Design Requirements for HNP Unit Nos. 1 and 2 HNP Unit No. 1 Final Safety Analysis Report (FSAR) Appendix F, "Conformance to Atomic Energy Commission (AEC) Criteria," describes the evaluation of the applicable design criteria.

Section F.2 of this appendix contains an evaluation of the HNP Unit No. 1 design criteria based on the current understanding of the intent of the "General Design Criteria for Nuclear Power Plant Construction," (GDC) issued for comment in July 1967. Section F.3 contains an evaluation of the unit's design criteria based on the current understanding of the intent of the "General Design Criteria for Nuclear Power Plants," effective May 21, 1971, and subsequently amended July 7, 1971. Each of the AEC criteria is followed by a discussion of the plant design.

Applicable references are made to facilitate comparisons. The HNP Unit No. 1 construction permit was received under the 70 general design criteria discussed in FSAR Section F.2.

Therefore, the HNP Unit No. 1 design bases were not explicitly developed in consideration of the 64 newer general design criteria discussed in Section F.3. The applicant has, however, evaluated the HNP Unit No. 1 design bases against the newer criteria. Therefore, the design criteria listed below were considered in the NRC staff's review of this LAR for HNP Unit No. 1.

HNP Unit No. 2 FSAR Section 3.1, "Conformance with Nuclear Regulatory Commission (NRC)

General Design Criteria," describes the evaluation of the applicable design criteria for Unit No.

2. The following design criteria were considered in the NRC staff's review of this LAR for HNP Unit No. 2.

Criterion 13 - Instrumentation and control. Instrumentation shall be provided to monitor variables and systems over their anticipated ranges for normal operation, for anticipated operational occurrences, and for accident conditions as appropriate to assure adequate safety,

including those variables and systems that can affect the fission process, the integrity of the reactor core, the reactor coolant pressure boundary (RCPB), and the containment and its associated systems. Appropriate controls shall be provided to maintain these variables and systems within prescribed operating ranges.

Criterion 14 - Reactor coolant pressure boundary. The reactor coolant pressure boundary

[RCPB] shall be designed, fabricated, erected, and tested to have an extremely low probability of abnormal leakage, of rapidly propagating failure, and of gross rupture.

Criterion 30 - Quality of reactor coolant pressure boundary. Components which are part of the

[RCPB] shall be designed, fabricated, erected, and tested to the highest quality standards practical. Means shall be provided for detecting and, to the extent practical, identifying the location of the reactor coolant leakage source.

Criterion 33 - Reactor coolant makeup. A system to supply reactor coolant makeup for protection against small breaks in the reactor coolant pressure boundary [RCPB] shall be provided. The system safety function shall be to assure that specified acceptable fuel design limits are not exceeded as a result of reactor coolant loss due to leakage from the [RCPB] and rupture of small piping or other small components which are part of the boundary. The system shall be designed to assure that for onsite electric power system operation (assuming offsite power is not available) and for offsite electric power system operation (assuming onsite power is not available) the system safety function can be accomplished using the piping, pumps, and valves used to maintain coolant inventory during normal reactor operation.

Criterion 35 - Emergency core cooling. A system to provide abundant emergency core cooling shall be provided. The system safety function shall be to transfer heat from the reactor core following any loss of reactor coolant at a rate such that (1) fuel and clad damage that could interfere with continued effective core cooling is prevented and (2) clad metal-water reaction is limited to negligible amounts.

Suitable redundancy in components and features and suitable interconnections, leak detection, isolation, and containment capabilities shall be provided to assure that for onsite electric power system operation (assuming offsite power is not available) and for offsite electric power system operation (assuming onsite power is not available) the system safety function can be accomplished, assuming a single failure.

3.0 TECHNICAL EVALUATION

Section 2.2 of this SE lists the proposed TS changes, as included in References 1 through 4, for the licensee to adopt TSTF-542, Revision 2. The following sections of the SE summarize the NRC staff's evaluation of each of these proposed changes.

3.1 Staff Evaluation of Proposed DRAIN TIME Definition As discussed in Section 2.2.1 above, the DRAIN TIME is the time it would take the RPV water inventory to drain from the current level to the TAF assuming the most limiting of the RPV penetrations flow paths with the largest flow rate, or a combination of penetration flow paths that could open due to a common mode failure, were to open and the licensee took no mitigating action.

The NRC staff reviewed the proposed drain time definition from the TSTF-542 traveler. For the purpose of NRC staff considerations, the term "break" describes a pathway for water to drain from the RPV that has not been prescribed in the "DRAIN TIME" definition in TSTF-542. Based on information furnished by the licensee, the NRC staff has determined that the licensee is appropriately adopting the principles of Drain Time as specified in TSTF-542. The NRC has reasonable assurance that the licensee will include all RPV penetrations below the TAF as potential pathways in the determination of drain time. As part of this evaluation, the NRC staff reviewed requests for additional information issued during the development of TSTF-542, Revision 2, which provided examples of bounding drain time calculations for three cases:

( 1) water level at or below the RPV flange; (2) water level above the RPV flange with fuel pool gates installed; and (3) water level above the RPV flange with fuel pool gates removed. The drain time is calculated by taking the water inventory above the break and dividing by the limiting drain rate until the TAF is reached. The limiting drain rate is a variable parameter depending on the break size and the reduction of elevation head above break location during the drain down event. The discharge point will depend on the lowest potential drain point for each RPV penetration flow path on a plant-specific basis. This calculation provides a conservative approach to determining the drain time of the RPV.

The NRC staff concluded that reasonable assurance exists that the licensee will use methods resulting in conservative calculations to determine RPV drain time, thereby, protecting Safety Limit 2.1.1.3, Which meets the requirements of 10 CFR 50.36(c)(3). Therefore, the NRC staff concludes that the licensee's proposed addition of DRAIN TIME to Section 1.1, "Definitions," of the HNP TSs is acceptable.

3.2 Staff Evaluation of Proposed TS 3.3.5.2, "Reactor Pressure Vessel (RPV) Water Inventory Control Instrumentation" The existing HNP TS 3.3.5.2, "Reactor Core Isolation Cooling (RCIC) System Instrumentation,"

would be renumbered as TS 3.3.5.3. This is an administrative change that achieves consistency within the HNP TSs and is acceptable.

The purpose of the proposed new TS 3.3.5.2 regarding RPV WIC Instrumentation is to support the requirements of revised TS LCO 3.5.2, and the proposed new definition of drain time. There are instrumentation and controls and their signal functions that are required for manual pump starts, or required as permissive or operational controls on the equipment and systems that provide water injection capability, certain start commands, pump protection, and isolation functions. These instruments are required to be operable if the systems that provide water injection and isolation functions are to be considered operable, as described in Section 3.3 of this SE for revised TS 3.5.2. For HNP, reactor operators have alternate, often more complex, means of starting and injecting water than the preferred simple push button start. Specifically, the proposed new TS 3.3.5.2 regarding RPV WIC Instrumentation supports operation of the CS and LPCI systems, including manual starts when needed, as well as the system isolation of the RHR system and the RWCU system. The equipment involved with each of these systems is described in the evaluation of TS 3.5.2 and the Bases for LCO 3.5.2.

3.2.1 Staff Evaluation of Proposed TS 3.3.5.2 LCO and Applicability In the LAR, the licensee proposed a new TS 3.3.5.2 to provide alternative instrumentation requirements to support manual initiation of the ECCS injection/spray subsystem required in revised TS 3.5.2 and automatic isolation of penetration flow paths that may be credited in the determination of DRAIN TIME. The current TSs contain instrumentation requirements related to

OPDRVs in TS Table 3.3.5.1-1, TS Table 3.3.6.1-1, TS Table 3.3.6.2-1, and TS 3.3.7.1. The requirements from Table 3.3.5.1-1 and Table 3.3.6.1-1 would be consolidated into new TS 3.3.5.2.

The proposed LCO 3.3.5.2 would state:

The RPV Water Inventory Control instrumentation for each Function in Table 3.3.5.2-1 shall be OPERABLE.

The proposed Applicability would state:

According to Table 3.3.5.2-1.

TSTF-542 selected Table 3.3.5.2-1 to contain those instrumentation Functions needed to support manual initiation of the low pressure ECCS injection/spray subsystem required by LCO 3.5.2, and automatic isolation of penetration flow paths that may be credited in a calculation of drain time. The Functions in Table 3.3.5.2-1 are moved from existing TS 3.3.5.1, "Emergency Core Cooling System (ECCS) Instrumentation," and TS 3.3.6.1, "Primary Containment Isolation Instrumentation" Functions that are required in Modes 4 or 5 or during OPDRVs. Creation of TS 3.3.5.2 places these Functions in a single location with requirements appropriate to support the safety function for TS 3.5.2. If plant-specific design and TSs require different functions to support manual initiation of a low pressure ECCS subsystem, those functions should be included in TS 3.3.5.2.

The NRC staff concluded that the licensee's proposed alternative is acceptable for HNP since either CS or LPCI (or both) subsystems would be available to perform the intended function to inject water into the RPV, which meets the conditions of the NRG-approved TSTF-542.

3.2.2 Staff Evaluation of Proposed TS 3.3.5.2 Actions For the changes described in detail in Section 2.2.2.2 above, the NRC staff has determined that the licensee's proposed new TS 3.3.5.2 Actions are sufficient and necessary, because when one or more instrument channels are inoperable, the equipment controlled by these instruments cannot complete the required functions in the normal manner. The Actions are evaluated as follows; Action A would be applicable when one or more instrument channels are inoperable from Table 3.3.5.2-1 and directs the licensee to immediately enter the Condition referenced in Table 3.3.5.2-1 for that channel.

Action B (concerning the RHR system isolation and RWCU system isolation functions) would be applicable when automatic isolation of the associated penetration flow path is credited as a path for potential drainage in calculating drain time. If the instrumentation is inoperable, Required Action 8.1 directs an immediate declaration that the associated penetration flow path(s) are incapable of automatic isolation. Required Action 8.2 requires an immediate re-calculation of drain time, but automatic isolation of the affected penetration flow paths cannot be credited.

Action C (concerning low reactor steam dome pressure permissive Functions necessary for low pressure ECCS subsystem manual injection valve opening) would address an event in which the permissive is inoperable. The function must be placed in the trip

condition within one hour. With the permissive function instrument in the trip condition, manual injection valve opening may now be performed using the preferred control board switches. This one-hour completion time is acceptable, because, despite the preferred start method being prevented, the reactor operator can take manual control of the pump and the injection valve to inject water into the RPV and achieve the safety function in that time. The time of one hour also provides reasonable time for evaluation and placing the channel in trip.

Action D (concerning pump discharge flow bypass Functions) would address actions when the bypass is inoperable and then there is a risk that the associated low pressure ECCS pump could overheat when the pump is operating and the associated injection valve is not fully open. In this condition, the operator can take manual control of the pump and the injection. Similar to the justification for Action C, while this is not the preferred method, the CS and LPCI subsystem pumps can be started manually and the valves can be opened manually. The 24-hour completion time is acceptable, because the functions can be performed manually and it allows time for the operator to evaluate the condition and have necessary repairs completed.

Action E would be needed, and become necessary, if the Required Actions and associated Completion Times of Condition C or D were not met. If they were not met, then the associated low pressure ECCS injection/spray subsystem might be incapable of performing the intended function, and the CS/LPCI subsystem would be declared inoperable immediately.

These Actions direct the licensee to take timely and appropriate actions upon entry into the Conditions referenced in Table 3.3.5.2-1. The NRC staff has determined that these Actions satisfy the requirements of 10 CFR 50.36(c)(2)(i) by providing a remedial action permitted by the TSs until the LCO can be met. The NRC staff has concluded that there is reasonable assurance that the licensee will take appropriate actions during an unexpected drain event to either prevent or to mitigate RPV water level being lowered to the TAF; therefore, the proposed changes are acceptable.

3.2.3 Staff Evaluation of Proposed TS 3.3.5.2 Surveillance Requirements The proposed new TS 3.3.5.2 SRs include Channel Checks and Channel Functional Tests numbered SR 3.3.5.2.1 and SR 3.3.5.2.2, respectively. The NRC staff finds that these tests are sufficient and adequate, because they are essential to ensure that the Functions of TS 3.3.5.2 are operable (i.e., capable of performing the specified safety function in support of TS 3.5.2 and protection from a potential drain down of the RPV in Modes 4 and 5). The NRC staff finds that the proposed SRs of LCO 3.3.5.2 are consistent with those described in Section 3.3.3 of the TSTF-542 justification, and that they satisfy 10 CFR 50.36(c)(3) by providing the specific SRs relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained.

SR 3.3.5.2.1 would require a Channel Check and applies to system isolation functions in TS Table 3.3.5.2-1 for RHR and RWCU. Performance of the Channel Check would ensure that a gross failure of instrumentation has not occurred. A Channel Check is normally a comparison of the parameter indicated on one channel to a similar parameter on other related channels. A Channel Check is significant in assuring that there is a low probability of an undetected complete channel failure and is a key safety practice to verifying the instrumentation continues

to operate properly between each Channel Functional Test. The frequency, in accordance with the SFCP, is consistent with the existing requirements and supports operating shift situational awareness.

SR 3.3.5.2.2 would require a Channel Functional Test and applies to all functions in TS Table 3.3.5.2-1. A Channel Functional Test is the injection of a simulated or actual signal into the channel as close to the sensor as practicable to verify operability of all devices in the channel required for channel operability. It would be performed on each required channel to ensure that the entire channel will perform the intended function. The frequency would be in accordance with the SFCP. This is acceptable because it is consistent with the existing requirements for these Functions.

TSTF-542 did not include SRs to verify or adjust the instrument setpoint derived from the allowable value using a Channel Calibration or a surveillance to calibrate the trip unit. This is because a draining event in Mode 4 or 5 is not an analyzed accident and, therefore, there is no accident analysis on which to base the calculation of a setpoint. As noted in TSTF-542:

The purpose of the Functions is to allow ECCS manual initiation or to automatically isolate a penetration flow path, but no specific RPV water level is assumed for those actions. Therefore, the Mode 3 Allowable Value was chosen for use in Modes 4 and 5 as it will perform the desired function. Calibrating the Functions in Modes 4 and 5 is not necessary, as TS 3.3.5.1 and TS 3.3.6.1 continue to require the Functions to be calibrated on an [established interval].

It is also noted in TSTF-542 that:

A draining event in Mode 4 or 5 is not an analyzed accident and, therefore, there are no accident analysis assumptions on response time.

The NRC staff has determined this is acceptable, because this is adequate to ensure that the channel responds with the required pumping systems to inject water when needed, and to isolate appropriate equipment when commanded.

Based on the above, the NRC staff has concluded that the proposed SRs of LCO 3.3.5.2 satisfy 10 CFR 50.36(c)(3) by providing the specific SRs relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained; therefore, the proposed changes are acceptable.

3.2.4 Staff Evaluation of Proposed Table 3.3.5.2-1, "RPVWater Inventory Control Instrumentation" In order to support the requirements of proposed TS 3.5.2, "Reactor Pressure Vessel (RPV)

Water Inventory Control," the associated instrumentation requirements would be designated in Table 3.3.5.2-1. These instruments would be required to be operable if the systems that provide water injection and isolation functions were to be considered operable, as described in the NRC staff's evaluation of TS 3.5.2 in Section 3.3 of this SE.

Proposed Table 3.3.5.2-1 specifies the instrumentation that shall be operable for each function in the table for Modes 4 and 5 (or other specified conditions), the required number of channels per function, conditions referenced from Required Action A.1, SR for the functions, the allowable value, and footnotes concerning items of the table.

Proposed Table TS 3.3.5.2-1, "RPV Water Inventory Control Instrumentation," presents details on the functions required to support the equipment and functions of TS 3.5.2. The NRC staff finds the presentation in this table to be acceptable, because this section of the application sufficiently discusses the purpose of the functions, the applicability, the number of required channels, the references to the Condition to be entered by letter (e.g., A, B, C) if the function is inoperable, the applicable SRs, the selection of the allowable value, and justification of differences between the existing and proposed TS functions. This RPV WIC Instrumentation set of requirements is acceptable, because it is adequate to ensure that the channels of instrumentation respond with the required accuracy permitting pumping systems to operate to inject water when needed and isolating equipment when commanded to support the prevention of or to mitigate a potential RPV draining event.

Each of the low pressure ECCS subsystems in Modes 4 and 5 can be started by manual alignment of a small number of components. Automatic initiation of a low pressure ECCS injection/spray subsystem may be undesirable in some scenarios, because it could lead to overflowing the RPV cavity, due to injection rates of thousands of gallons per minute.

Considering the TS 3.5.2 Action statements as the drain time decreases (e.g., the proposed TS 3.5.2, Action E, prohibits plant conditions that could result in drain times less than one hour),

there is sufficient time for the reactor operators to take manual action to stop a draining event, and to manually start a low pressure ECCS injection/spray subsystem or initiate an additional method of water injection as needed. Consequently, there is no need for automatic initiation of the low pressure ECCS to respond to an unexpected draining event. This is acceptable, because a draining event is a slow evolution when compared to an at-power design basis LOCA.

3.2.4.1 Staff Evaluation of Proposed Table 3.3.5.2-1 Functions For the Table 3.3.5.2-1 Functions 1.a and 2.a, CS and LPCI Systems, Reactor Steam Dome Pressure - Low (Injection Permissive), these signals would be used as permissives and protection for these low pressure ECCS injection/spray subsystem manual initiation functions.

This function would ensure that the reactor pressure has fallen to a value below these subsystems' maximum design pressure before permitting the operator to open the injection valves of the low pressure ECCS subsystems. Even though the reactor steam dome pressure is expected to always be below the low pressure ECCS maximum design pumping pressure during Modes 4 and 5, the Reactor Steam Dome Pressure - Low signals would be required to be operable and capable of permitting initiation of the ECCS. The proposed allowable value would be s 476 psig, with four required channels per function, as it is currently in HNP TS Table 3.3.5.1-1.

For the Table 3.3.5.2-1 Functions 1.b and 2.b, CS and LPCI Systems, Pump Discharge Flow - Low (Bypass), these minimum flow instruments were proposed to protect the associated low pressure ECCS pumps from overheating when the pump is operating and the associated injection valve is not fully open.

For LPCI, the minimum flow line valve is opened when low flow is sensed, and the valve is automatically closed when the flow rate is adequate to protect the pump. The proposed required channels per function would be 1 per subsystem, as it is currently found in HNP TS Table 3.3.5.1-1.

For CS, the minimum flow line valve is opened when low flow is sensed, and the valve is automatically closed when the flow rate is adequate to protect the pump, yet low enough to ensure that the closure of the minimum flow valve is initiated to allow full flow into the core. The proposed required channels per function is 1 per subsystem, as it is currently found in HNP TS Table 3.3.5.1-1.

The proposed allowable values for Functions 1.b and 2.b are as follows (current values moved from HNP TS Table 3.3.5.1-1 ):

cs ~ 610 gpm and :5 825 gpm ~ 570 gpm and :5 745 gpm LPCI ~ 1670 gpm and :5 2205 gpm ~ 1675 gpm and :5 2215 gpm For Table 3.3.5.2-1 Function 3.a, RHR System Isolation, Reactor Vessel Water Level - Low, Level 3, the function would only be required to be operable when automatic isolation of the associated penetration flow path is credited in the drain time calculation. The proposed number of required instrument channels is 2 in one trip system. The condition that the RHR system integrity be maintained is a concept related to OPDRVs, so it would not be carried over into TS 3.3.5.2 for RPV WIC Instrumentation. Reactor Vessel Water Level - Low, Level 3 signals are initiated from four level transmitters that sense the difference between the pressure due to a constant column of water (reference leg) and the pressure due to the actual water level (variable leg) in the vessel. While four channels (two channels per trip system) of the Reactor Vessel Water Level - Low, Level 3 Function are available, only two channels (all in the same trip system) are required to be OPERABLE. The allowable value was chosen to be the same as the Primary Containment Isolation Instrumentation Reactor Vessel Water Level - Low, Level 3, Allowable Value from LCO 3.3.6.1, which is ~ 0 inches.

For Table 3.3.5.2-1 Function 4.a, RWCU System Isolation, Reactor Vessel Water Level - Low Low, Level 2, the function is only required to be operable when automatic isolation of the associated penetration flow path is credited in the drain time calculation. The proposed number of required instrument channels is 2 in one trip system. Reactor Vessel Water Level - Low Low.

Level 2 signals are initiated from four level transmitters that sense the difference between the pressure due to a constant column of water (reference leg) and the pressure due to the actual water level (variable leg) in the vessel. While four channels (two channels per trip system) of the Reactor Vessel Water Level - Low Low, Level 2 Function are available, only two channels (all in the same trip system) are required to be OPERABLE. This proposed change is a new requirement in Modes 4 and 5 for the RWCU system. However, the instrumentation function is the same as current TS Table 3.3.6.1, Function 5.d, which contains the requirements for Modes 1, 2, and 3, with the same allowable value, ~ -47 inches.

The NRC staff finds that the proposed new LCO 3.3.5.2 correctly specifies the lowest functional capability or performance levels of equipment required for safe operation of the facility. There is reasonable assurance that the Required Actions to be taken when the LCO is not met can be conducted without endangering the health and safety of the public. This meets the requirements of 10 CFR 50.36(c)(2)(i) and, therefore, the NRC staff concludes that the proposed changes to LCO 3.3.5.2 are acceptable.

3.3 Staff Evaluation of TS 3.5.2, Reactor Pressure Vessel (RPV) Water Inventory Control The NRC staff reviewed the water sources that would be applicable to the proposed TS 3.5.2.

The proposed LCO 3.5.2 would state, in part, "One low pressure ECCS injection/spray subsystem shall be OPERABLE."

One low pressure ECCS injection/spray subsystem would consist of either one CS subsystem or one LPCI subsystem. A CS subsystem consists of one motor driven pump, piping, and valves to transfer water from the suppression pool or condensate storage tanks to the RPV. A LPCI subsystem consists of one motor driven pump, piping, and valves to transfer water from the suppression pool to the RPV.

The ECCS pumps are high-capacity pumps, with flow rates of thousands of gallons per minute (gpm). Most RPV penetration flow paths would have a drain rate on the order of tens or hundreds of gpm. The manual initiation/start of an ECCS pump would provide the necessary water source to counter the drain rates resulting from postulated events. The LPCI subsystem is to be considered operable during alignment and operation for decay heat removal if it is capable of being manually realigned and not otherwise inoperable. Decay heat removal in Modes 4 and 5 is not affected by the proposed HNP TS change, as these requirements on the number of shutdown cooling subsystems that must be operable and in operation to ensure adequate decay heat removal from the core are unchanged. These requirements can be found in the HNP TS 3.4.8, "Residual Heat Removal (RHR) Shutdown Cooling System - Cold Shutdown," TS 3.9.7, "Residual Heat Removal (RHR) - High Water Level," and TS 3.9.8, "Residual Heat Removal (RHR) - Low Water Level." These HNP decay heat removal requirements are similar to the corresponding STS; specifically, NUREG-1433 TS 3.4.9, TS 3.9.8, and TS 3.9.10. Based on these considerations, the NRC staff finds that the available water sources and systems provide reasonable assurance that the lowest functional capability required for safe plant operation is maintained for the specified operational modes, thus ensuring that the relevant safety limits are protected.

The proposed TS 3.5.2, "Reactor Pressure Vessel (RPV) Water Inventory Control,"

LCO contains two parts. The first part states that drain time of RPV water inventory to the TAF shall be ~ 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months , and the second part states that one low pressure ECCS injection/spray subsystem shall be OPERABLE. The proposed Applicability for TS 3.5.2 is Modes 4 and 5.

The NRC staff reviewed the proposed TS 3.5.2, focusing on how the proposed changes maintain or establish requirements to ensure that the fuel remains covered with water during potential drain events. The proposed TS 3.5.2 contains Conditions A through E, which are based on either required ECCS injection/spray subsystem operability or drain time.

The current TS 3.5.2 LCO states that two low pressure ECCS injection/spray subsystems shall be OPERABLE, whereas the proposed LCO 3.5.2 states that only one low pressure ECCS injection/spray subsystem shall be OPERABLE. This change is reflected in Condition A. The change from two low pressure ECCS injection/spray subsystems OPERABLE to one low pressure ECCS injection/spray subsystem OPERABLE is because this redundancy is not required for the applicable modes. With one ECCS injection/spray subsystem OPERABLE, and the availability of non-safety related injection sources of sufficient capacity to mitigate potential drain down events, defense-in-depth will be maintained. This defense-in-depth approach is consistent with those for other events considered during shutdown with no additional single failure assumed. The drain time controls, in addition to the required low pressure ECCS

injection/spray subsystem, provide reasonable assurance that an unexpected draining event can be prevented or mitigated before the RPV water level would be lowered to the TAF.

The proposed Mode 4 and 5 Applicability of TS 3.5.2 is appropriate, given that the TS requirements on ECCS in Modes 1, 2, and 3 will be unaffected.

The proposed Condition A states that if the required ECCS injection/spray subsystem is inoperable, it is to be restored to OPERABLE status within 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months .

Proposed Condition B states that if Condition A is not met, a method of water injection capable of operating without offsite electrical power shall be established immediately. The proposed Condition B provides adequate assurance of an available water source should Condition A not be met within the 4-hour completion time.

The proposed Condition C states that for a DRAIN TIME < 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months and .:: 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months , to (C.1) verify secondary containment boundary is capable of being established in less than the DRAIN TIME, with a completion time of 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months , and (C.2) verify each secondary containment penetration flow path is capable of being isolated in less than the DRAIN TIME, with a completion time of 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months , and (C.3) verify required standby gas treatment subsystem(s) are capable of being placed in operation in less than the DRAIN TIME, with a completion time of 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months . The proposed Condition C provides adequate protection when the DRAIN TIME is

< 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months and .:: 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months because of the ability to establish secondary containment, isolate additional flow paths, and have the standby gas treatment subsystem capable of being placed in operation in less time.

The proposed Condition D states that when DRAIN TIME < 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months to (D.1) immediately initiate action to establish an additional method of water injection with water sources capable of maintaining RPV water level> TAF for.:: 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months , and (D.2) immediately initiate action to establish secondary containment boundary, and (D.3) immediately initiate action to isolate each secondary containment penetration flow path or verify it can be manually isolated from the control room, and (D.4) immediately initiate action to verify required standby gas treatment subsystem(s) are capable of being placed in operation. Additionally, there is a note stating that required ECCS injection/spray subsystem or additional method of water injection shall be capable of operating without offsite electrical power, which is similar to proposed Condition B.

The proposed Condition D provides adequate protection should the DRAIN TIME be < 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months , because of the requirements to immediately establish an additional method of water injection (without offsite electrical power), establish secondary containment, isolate additional flow paths, and have the standby gas treatment subsystem capable of being placed in operation. These are all appropriate measures in response to a potential drain down event with the plant in Modes 4 and 5.

The proposed Condition E states that when the Required Action and associated Completion Time of Condition C or D are not met, or the DRAIN TIME is < 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months , then immediately initiate action to restore DRAIN TIME to.:: 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months . The proposed Condition Eis new, as it is not present in the current HNP TS. The proposed Condition E is acceptable, as it provides the necessary step to restore the DRAIN TIME to.:: 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months should the other conditions not be met, or if the DRAIN TIME is< 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months .

The NRC staff reviewed the proposed changes to TS 3.5.2 and finds them acceptable, based on the actions required to mitigate the water level reaching the TAF with the water sources available and maintaining DRAIN TIME.:: 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months . LCO 3.5.2 correctly specifies the lowest

functional capability or performance levels of equipment required for safe operation of the facility. There is reasonable assurance that the required actions to be taken when the LCO is not met can be conducted without endangering the health and safety of the public and, therefore, they are acceptable.

3.3.1 Staff Evaluation of Proposed TS 3.5.2 Surveillance Requirements The proposed TS 3.5.2 SRs (listed in Section 2.2.3 above) include verification of DRAIN TIME, verification of water levels/volumes that support ECCS injection/spray subsystems, verification of water filled pipes to preclude water hammer events, verification of correct valve positions for the required ECCS injection/spray subsystem, operation of the ECCS injection/spray systems through the recirculation line, verification that valves credited for automatic isolation can be actuated to the isolation position, and verification that the required ECCS injection/spray subsystem can be manually operated. Each of the eight SRs are described below.

SR 3.5.2.1: The DRAIN TIME would be determined or calculated, and required to be verified to be~ 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months in accordance with the SFCP. This surveillance would verify that the LCO for DRAIN TIME is met. Numerous indications of changes in RPV level are available to the reactor operators. The period of 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months is considered reasonable to identify and initiate action to mitigate draining of reactor coolant (normally 3 operating shifts). Changes in RPV level would necessitate recalculation of the DRAIN TIME.

SR 3.5.2.2: This surveillance requires that the suppression pool water level is verified to be

~ 146 inches, to ensure that adequate pump net positive suction head and vortex prevention is available for the LPCI subsystem required to be OPERABLE by the LCO. Indications are available either locally or in the control room for suppression pool water level. This surveillance would be required to be performed in accordance with the SFCP.

SR 3.5.2.3: This surveillance requires that the suppression pool water level is verified to be

~ 146 inches, or that the condensate storage tank water level is~ 13 feet, to ensure that adequate pump net positive suction head and vortex prevention is available for the CS subsystem required to be OPERABLE by the LCO. Indications are available either locally or in the control room regarding suppression pool water level and condensate storage tank water level. This surveillance would be required to be performed in accordance with the SFCP.

SR 3.5.2.4: The surveillance requirement to verify the ECCS injection/spray subsystem piping is sufficiently filled with water would be retained from the existing TS 3.5.2. The proposed change would update the SR to reflect the change to LCO 3.5.2, which would require, in part, one low pressure ECCS injection/spray subsystem to be operable instead of two. SR 3.5.2.3 wording would change from "Verify, for each required ECCS ... " to "Verify, for the required ECCS .... " This change clarifies the requirement to maintain consistency with the proposed LCO. Maintaining the pump discharge lines of the required ECCS injection/spray subsystem sufficiently full of water ensures that the ECCS subsystem will perform properly. This will also prevent water hammer following an ECCS initiation signal. One acceptable method of ensuring that the lines are full is to vent at the high points. This surveillance would be required to be performed in accordance with the SFCP.

SR 3.5.2.5: The SR to verify the correct alignment for manual, power operated, and automatic valves in the required ECCS subsystem flow path would be retained from the existing TS 3.5.2.

Similar to the change discussed above for proposed SR 3.5.2.4, changes to SR 3.5.2.5 would clarify a proposed requirement for LCO 3.5.2. The proposed SR wording, "Verify for the

required ECCS injection/spray subsystem, each manual .... " would replace "Verify each required ECCS injection/spray subsystem manual. ... " SR 3.5.2.5 would provide assurance that the proper flow path will be available for ECCS operation to support TS 3.5.2. This SR would not apply to valves that are locked, sealed, or otherwise secured in position, since these valves would be verified to be in the correct position prior to locking, sealing, or securing.

This SR is modified by two notes: (1) A Low Pressure Coolant Injection (LPCI) subsystem may be considered operable during alignment and operation for decay heat removal if capable of being manually realigned and not otherwise inoperable, and (2) Not required to be met for system vent flowpaths opened under administrative control. For Note 1, in Modes 4 and 5, the RHR system may operate in the shutdown cooling mode to remove decay heat and sensible heat from the reactor and the RHR valves that are required for LPCI subsystem operation may be aligned for decay heat removal. Note 1 allows a required LPCI subsystem of the RHR system to be considered operable for the ECCS function if all the required valves in the LPCI flow path can be manually realigned (remote or local) to allow injection into the RPV, and the system is not otherwise inoperable. This will ensure adequate core cooling if an inadvertent RPV draindown should occur. For Note 2, the administrative control would allow a dedicated individual who can rapidly close the system vent flow path if directed. This surveillance would be required to be performed in accordance with the SFCP.

SR 3.5.2.6: The required ECCS injection/spray subsystem would be required to be operated through its recirculation line for~ 10 minutes in accordance with the SFCP. This would demonstrate that the subsystem is capable for operation to support TS 3.5.2. Testing the ECCS injection/spray subsystem through the recirculation line is necessary to avoid overfilling the refueling cavity. The minimum operating time of 10 minutes is based on engineering judgement. This surveillance would be required to be performed in accordance with the SFCP.

SR 3.5.2.7: Verification that each valve credited for automatically isolating a penetration flow path actuates to the isolation position on an actual or simulated RPV water level isolation signal would be required to prevent RPV water inventory from dropping below the TAF, should an unexpected draining event occur. This surveillance would be required to be performed in accordance with the SFCP.

SR 3.5.2.8: This SR would state, "Verify the required ECCS injection/spray subsystem can be manually operated." It would demonstrate that the required CS or LPCI subsystem could be manually operated, using the associated pump and valve switches, to provide additional RPV water inventory, if needed. Vessel injection/spray may be excluded from the SR, per the existing Note. This surveillance would be required to be performed in accordance with the SFCP.

The NRC staff evaluated each of these proposed SRs associated with the proposed LCO 3.5.2 and concluded that they are appropriate for ensuring the operability of the equipment and instrumentation specified in LCO 3.5.2. Furthermore, the NRC staff concluded that each of the proposed SRs are acceptable, since they meet the requirements of 10 CFR 50.36(c)(2)(ii) regarding insights gained via operating experience and 10 CFR 50.36(c)(3) for surveillance requirements by ensuring that the necessary quality of systems and components are maintained.

3.4 Staff Evaluation of TS Table 3.3.5.1-1, "Emergency Core Cooling System Instrumentation" LCO 3.3.5.1 currently states that, "[t]he ECCS instrumentation for each Function in Table 3.3.5.1-1 shall be OPERABLE," with the applicability as stated in the table. Table 3.3.5.1-1, "Emergency Core Cooling System Instrumentation," currently contains requirements for function operability during Modes 4 and 5 when the associated ECCS subsystem(s) are required to be operable. Conforming changes were proposed for the Actions of LCO 3.3.5.1 as well, to reflect the proposed changes to TS Table 3.3.5.1-1.

For the following Functions in Table 3.3.5.1-1, Mode 4 and 5 requirements would be deleted:

1. Core Spray System (a) Reactor Vessel Water Level - Low Low Low, Level 1 (c) Reactor Steam Dome Pressure - Low (Injection Permissive)

(d) Core Spray Pump Discharge Flow - Low (Bypass)

2. LPCI (a) Reactor Vessel Water Level - Low Low Low, Level 1 (c) Reactor Steam Dome Pressure - Low (Injection Permissive)

(f) Low Pressure Coolant Injection Pump Start - Time Delay Relay (Pumps A, B, C, and 0)

(g) Low Pressure Coolant Injection Pump Discharge Flow - Low (Bypass)

These functions would be deleted to support the consolidation of RPV WIC instrumentation requirements into proposed new TS 3.3.5.2. The requirements for Functions 1.c, 1.d, 2.c, and 2.g would be moved to proposed TS Table 3.3.5.2-1, as discussed in Section 3.2.4.1 of this SE.

For the other TS Table 3.3.5.1-1 Functions, 1.a, 2.a, and 2.f, the Mode 4 and 5 requirements would not be retained. The HNP TS currently require automatic initiation of ECCS pumps on low Reactor Vessel water level. However, in Modes 4 and 5, automatic initiation of ECCS pumps could result in overfilling the refueling cavity or water flowing into the main steam lines, potentially damaging plant equipment. The NRC staff finds acceptable the deletion of TS Table 3.3.5.1-1, Functions 1.a, 2.a, and 2.f, because manual ECCS initiation is preferred over automatic initiation during Modes 4 and 5, and the operators would be able to use other more appropriately sized pumps if needed to mitigate a draining event. Also, there is no STS equivalent for Function 2.f for the LPCI pump start time delay relays in Modes 4 and 5. The purpose of the time delay is to stagger the automatic start of LPCI pumps, thus limiting the starting transients on the emergency buses. The staggered starting of ECCS pumps is unnecessary for manual ECCS operation.

3.5 Staff Evaluation of Proposed Technical Variations SNC proposed the following nine technical variations from the TS changes described in TSTF-542 or the applicable parts of the NRC staffs SE for TSTF-542. The licensee stated in the LAR and its supplements that these variations do not affect the applicability of TSTF-542 or the NRC staff's SE for TSTF-542 to the proposed license amendment. The NRC staff evaluated each variation below.

3.5.1 Variation 1, Supported Feature HNP Unit 1 and Unit 2 TS 3.3.5.1, "Emergency Core Cooling System (ECCS) Instrumentation,"

Required Actions 8.1, C.1, and E.1 read slightly differently than the STS. For the HNP TS, the Required Actions for these conditions state (in part):

Declare supported feature(s) inoperable.

For the STS and TSTF-542, the corresponding Required Actions state:

Declare supported features(s) inoperable when its redundant feature ECCS initiation capability is inoperable.

The Completion Times for both HNP TS 3.3.5.1 and the STS states (in part):

1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months from discovery of loss of initiation capability for feature(s) in both divisions.

The NRC staff finds that, based on when the completion time starts, the additional words shown in Required Actions 8.1, C.1, and E.1 for STS 3.3.5.1 are not needed for the corresponding HNP TSs, as the resultant action and completion time is the same. Therefore, the existing wording for the HNP TSs is acceptable.

3.5.2 Variation 2, CS and LPCI Flow Transmitter The HNP CS and LPCI subsystems have one flow transmitter per ECCS subsystem to detect the associated subsystem's flow rates, whereas the STS assume one flow transmitter per ECCS pump to detect the associated subsystem's flow rates. Each HNP CS subsystem has one CS pump, and each HNP LPCI subsystem has two RHR pumps. The licensee proposes to maintain the one channel per subsystem requirement for new Table 3.3.5.2-1, Functions 1.b.

and 2.b. For the CS subsystem, this variation of "1 per subsystem" versus "1 per pump" is editorial (one pump per subsystem), so keeping the phrase "1 per subsystem" will maintain consistency with the current HNP TS language, and is acceptable.

Existing HNP TS Table 3.3.5.1-1 for CS (Function 1.d) and LPCI (Function 2.g) specifies that the required channels per function is "1 per subsystem" for Modes 1, 2, and 3; and for Modes 4 and 5, when the associated subsystem(s) are required to be operable. The NRC staff finds that this current instrumentation requirement provides sufficient overheating protection for the CS and LPCI injection pumps in Modes 4 and 5 and is consistent with the existing HNP TS; therefore, this variation is acceptable.

3.5.3 Variation 3, TS Table 3.3.5.2-1 Footnote The licensee is proposing to add a footnote in new TS Table 3.3.5.2- to clarify the intent of allowing credit for an operable LPCI subsystem when it is aligned and operating in the decay heat removal mode of RHR. The footnote would state:

(c) Function not required to be OPERABLE while associated pump is operating in decay heat removal when minimum flow valve is closed and deactivated.

The NRC considers this appropriate since the associated RHR pump minimum flow valve (while operating in the decay heat removal mode) is closed and deactivated to prevent inadvertent

vessel drain down events. Because the minimum flow valve is closed and deactivated, the associated TS Table 3.3.5.2-1, Function 2.b would not be required to be operable.

The NRC staff finds that the added footnote (c) associated with the LPCI subsystem in new TS Table 3.3.5.2-1 is appropriate. Without the footnote, TS 3.3.5.2, Condition D would require that the associated RHR pump be declared inoperable, which would be contrary to the Note for existing SR 3.5.2.4 (new SR 3.5.2.5), which allows the LPCI subsystem to be considered OPERABLE when aligned for decay heat removal; therefore this variation is acceptable.

3.5.4 Variation 4, Manual Initiation Logic The HNP Unit 1 and Unit 2 TS do not include a manual initiation logic function for the CS or LPCI subsystems. Considering the logic design, there is not a single switch that will start all subsystems of the associated ECCS system, as is assumed in the STS. HNP does, however, have the capability to manually start the ECCS pumps individually. Since the manual initiation logic function does not exist at HNP, manual initiation functions for LPCI and CS are not being included in Table 3.3.5.2-1. Additionally, since the manual initiation functions are not included in Table 3.3.5.2-1, the associated Logic System Functional Test would likewise not be required for TS 3.3.5.2; therefore, TS 3.3.5.2 as proposed for HNP Unit 1 and Unit 2 TS does not include a Logic System Functional Test SR. The manipulation of subsystem components from the main control room would be verified in accordance with new SR 3.5.2.8. This surveillance Would verify that the required CS or LPCI subsystem (including the associated pump switches and valve(s)) can be manually operated to provide additional RPV water inventory, if needed, using controls and indications that are currently available in the main control room. In the LAR, the licensee described how adequate time for the operators to take action is assured.

The NRC staff reviewed this variation and determined that although HNP does not have the capability to start an ECCS subsystem with a single button, the components that provide water supply and injection into the RPV can be started from the main control room as required to support Mode 4 and 5 operations. The manipulation of subsystem components from the main control room would be verified in accordance with new SR 3.5.2.8. This SR would verify that the required CS or LPCI subsystem (including the associated pump switches and valve(s)) can be manually operated to provide additional RPV water inventory, if needed. Therefore, the NRC staff finds that Variation 4 is acceptable.

3.5.5 Variation 5, LPCI Realignment The STS Note on LCO 3.5.2 regarding realignment to the LPCI mode is located in the HNP SR 3.5.2.4 (new SR 3.5.2.5). This has no effect on the adoption of TSTF-542 and is an acceptable deviation.

The STS Note in LCO 3.5.2, ECCS - Shutdown, shown below, is located in the current HNP SR 3.5.2.4:

NOTE--------------------------------------

One LPCI subsystem may be considered OPERABLE during alignment and operation for decay heat removal if capable of being manually realigned and not otherwise inoperable

The licensee has proposed a slightly modified Note 1 in new SR 3.5.2.5, which states:

N()l"E:--------------------------------------

A Low Pressure Coolant Injection (LPCI) subsystem may be considered ()PE:RABLE: during alignment and operation for decay heat removal if capable of being manually realigned and not otherwise inoperable.

l"he NRC staff finds that the minor proposed change to SR 3.5.2.5 (previously SR 3.5.2.4) is appropriate, and that the Note is located in the applicable section of the HNP l"S, since it is related to verification of system alignment; therefore, this variation is acceptable.

3.5.6 Variation 6, l"S 3.6.1.3 Condition F Revised HNP l"S 3.6.1.3, Condition F (which corresponds to Sl"S Condition H) deletes the phrase, "Initiate action to suspend operations with a potential for draining the reactor vessel."

l"he NRC staff notes that this phrase is also being deleted from the Sl"S per l"Sl"F-542. Since

()PDRVs are only performed in Mode 4 or Mode 5, this phrase that was contained in the Sl"S was unnecessary; therefore, this variation is acceptable.

3.5.7 Variation 7, Inverters HNP does not have an "Inverters - Operating" or an "Inverters - Shutdown" l"S. As stated in the HNP improved l"S Conversion:

Inverters, as utilized in the NURE:G-1433 Sl"S (i.e., inverters that power many required systems and that are required to be powered by the DC sources to meet accident analysis assumptions), do not exist in the HNP. As such, NURE:G-1433 LCO 3.8.7 and LCO 3.8.8, their associated Bases, and all references to them have been deleted. l"he LCOs that follow have been renumbered to reflect this deletion. l"he only inverters that need to be powered from DC sources are the LPCI inverters, which only provide power to the LPCI subsystems. l"hese two inverters are covered by an SR in NURE:G(-1433] LC() 3.5.1 (E:CCS) since they only impact the LPCI subsystems.

l"he NRC staff finds that the inverters are not specifically addressed in the HNP l"S; therefore, no changes are required with respect to l"Sl"F-542, and this variation is acceptable.

3.5.8 Variation 8, Surveillance Frequency Control Program l"he HNP l"Ss contain a SFCP. l"herefore, the Surveillance Requirement Frequencies for new l"Ss 3.3.5.2 and 3.5.2 are "In accordance with the Surveillance Frequency Control Program."

HNP is adopting the recommended frequencies in l"Sl"F-542 (within its SFCP), except that the surveillance frequency corresponding to new SR 3.3.5.2.2. for the performance of the CHANNE:L FUNCl"l()NAL l"E:Sl" will be "92 days on an ALl"E:RNAl"E: l"E:Sl" BASIS."

Section 3.2.3 of this SE: describes SR 3.3.5.2.2. l"he NRC staff finds that this is consistent with the current licensing basis for existing SRs 3.3.5.1.2 and 3.3.6.1.2. Performing these CHANNE:L FUNCl"IONAL l"E:Sl" SRs on an ALl"E:RNAl"E: l"E:Sl" BASIS was approved by the

NRC in Amendments 234 and 176, for HNP Units 1 and 2, respectively (Reference 9). In addition, since the HNP units are on two-year fuel cycles, the 18-month frequencies in TSTF-542 would be 24-month frequencies for HNP. The proposed variation retains the current licensing basis for the plant; therefore, the NRC staff finds this variation acceptable.

3.5.9 Variation 9, Table 3.3.5.2-1 on Applicability of ECCS Functions In accordance with TSTF-542, TS Table 3.3.5.2-1, Function 1.a (CS, Reactor Steam Dome Pressure - Low (Injection Permissive)), and Function 2.a (LPCI, Reactor Steam Dome Pressure - Low (Injection Permissive)) are required in Modes 4 and 5. Prior to TSTF-542 , the analogous Functions 1.c and 2.c in HNP TS Table 3.3.5.1-1 had a Mode 4 and 5 applicability modified by a footnote specifying that these functions were only required when the associated ECCS subsystem(s) were required to be operable. The footnote was omitted inadvertently from Table 3.3.5.2-1, Functions 1.a and 2.a in TSTF-542. The licensee proposed a variation to affix Footnote (a), which would state, "Associated with an ECCS subsystem required to be OPERABLE by LCO 3.5.2, 'Reactor Pressure Vessel Water Inventory Control,"' to the "Required Channels Per Function" column of Functions 1.a and 2.a of new TS Table 3.3.5.2-1.

Without the footnote, the Reactor Steam Dome Pressure - Low (Injection Permissive) functions would be required to be operable for all low pressure ECCS subsystems, regardless of whether they are credited for meeting the ECCS operability requirements of LCO 3.5.2. These instruments are required to be operable only if the systems that provide water injection and isolation functions are required to be operable. In Modes 4 and 5, with the reactor steam dome at atmospheric pressure, these functions only serve to satisfy permissives for opening low pressure ECCS injection valves for manual actuation. The NRC staff finds that the proposed variation is acceptable, since the CS or LPCI subsystems would still be available to perform the intended function to inject water into the RPV, which meets the intent of TSTF-542 and maintains the current licensing basis for HNP.

3.6 Staff Evaluation of Proposed Deletion of References to OPDRVs Section 2.2.4 above lists the numerous OPDRVs references proposed for deletion. The proposed changes would replace the existing specifications related to OPDRVs with revised specifications for RPV WIC. For example, the proposed changes would remove "operations with a potential for draining the reactor vessel," the acronym "OPDRVs," and related concepts such as "RHR Shutdown Cooling System integrity maintained," and Required Actions to "suspend OPDRVs." The term OPDRVs is not specifically defined in the TSs and historically has been subject to inconsistent application by licensees. The changes discussed in this SE are intended to resolve any ambiguity by creating a new RPV WIC TS with attendant equipment operability requirements, required actions and SRs and deleting references to OPDRVs throughout the TSs.

The existing HNP TSs contain instrumentation requirements related to OPDRVs in four TSs; three of them, which have the OPDRVs phrases described above, and TS 3.3.5.1. The proposed TS 3.3.5.2 consolidates the instrumentation requirements into a single location to simplify the presentation and provide requirements consistent with TS 3.5.2. The remaining TSs with OPDRVs requirements are for containment, containment isolation valves, standby gas treatment system, control room habitability, temperature control, and electrical sources. Each of these systems' requirements during OPDRVs were proposed for consolidation into new TS 3.5.2 for RPV WIC, based on the appropriate plant conditions and calculated Drain Time.

The NRC staff has determined that the deletion of OPDRVs references, along with the corresponding editorial changes, are appropriate because the proposed TSs governing RPV WIC and the associated instrumentation, TSs 3.5.2 and 3.3.5.2, respectively, are a simplified alternative set of controls for ensuring water level is maintained above the TAF; therefore, these changes are acceptable.

3.7 Staff Evaluation of TS 3.10, Special Operations and TSTF-484 The current HNP TS LCO 3.10.1, "lnservice Leak and Hydrostatic Testing Operation," allows performance of an inservice leak test or hydrostatic test with the average reactor coolant temperature greater than 212°F, while considering operational conditions to still be in Mode 4, provided certain secondary containment LCOs are met.

TSTF-484, Revision 0, "Use of TS 3.10.1 for Scram Time Testing Activities," (References 10, 12, 13, and 14) revised LCO 3.10.1 to expand its scope to include operations where temperature exceeds 212°F: (1) as a consequence of maintaining adequate reactor pressure for an inservice leak or hydrostatic test, or (2) as a consequence of maintaining adequate reactor pressure for control rod scram time testing initiated in conjunction with an inservice leak or hydrostatic test.

By Amendment Nos. 251 and 195 (Units 1 and 2, respectively) dated May 17, 2007 (Reference 11 ), the NRC approved changes to HNP TS LCO 3.10.1 in accordance with TSTF-484. The NRC staff's SE for these amendments stated, in part, that, "two low-pressure emergency core cooling systems (ECCS) injected/spray subsystems are required to be operable in Mode 4 by TS 3.5.2, 'ECCS-Shutdown."' However, per the proposed new LCO 3.5.2, only one low pressure ECCS injection/spray subsystem would be required to be operable in Mode 4.

The NRC staff has determined that changing from two ECCS injection/spray subsystems to one ECCS injection/spray subsystem is acceptable, because, as stated previously in Section 3.3.1 of this SE, this level of redundancy is not required, even during application of LCO 3.10.1.

When the licensee applies LCO 3.10.1 at the end of a refueling outage, an exceptionally large volume of water is present in the reactor vessel since the vessel is nearly water solid. There is much more water in the reactor vessel than is present during power operation and more than is present puring most of an outage. Small leaks from the reactor coolant system would be detected by inspections before a significant loss of inventory occurred. In the event of a large reactor coolant system leak, the RPV would rapidly depressurize and allow operation of the low pressure ECCS. At low decay heat values, and near Mode 4 conditions, the stored energy in the reactor core will be very low. Therefore, the reasoning that operators would have time to respond with manual actions to start any ECCS pumps and properly align valves for injection from the control room remains valid.

As stated in Section 3.3 of this SE, with one ECCS injection/spray subsystem and additional, non-safety related injection sources, defense-in-depth will be maintained. The defense-in-depth measure is consistent with other events considered during shutdown with no additional single failure assumed. The drain time controls, in addition to the required ECCS injection/spray subsystem, provide reasonable assurance that an unexpected draining event can be prevented or mitigated before the RPV water level would be lowered to the TAF.

Based on the NRC staff's assessment in this SE and its review of Reference 11, the staff determined that the proposed LCOs 3.3.5.2 and 3.5.2 are consistent with TSTF-542 and are

adequate to ensure the performance of required safety functions for the applicable modes of operation, including the application of LCO 3.10.1. Therefore, the proposed changes are acceptable.

3.8 Technical Evaluation Conclusion HNP Safety Limit 2.1.1.3 requires that reactor vessel water level shall be greater than the top of active irradiated fuel. Maintaining water level above the TAF ensures that the fuel cladding fission product barrier is protected during shutdown conditions. The proposed TS changes evaluated within this SE establish new LCO requirements that address the preventive and mitigative equipment and associated instrumentation that provide an alternative means to support Safety Limit 2.1.1.3 during Mode 4 and 5 operations.

The reactor coolant system is at a low operating temperature(~ 212 °F) and is depressurized during Modes 4 and 5 conditions. An event involving a loss of inventory while in the shutdown condition does not exceed the capacity of one ECCS subsystem. The accidents that are postulated to occur during shutdown conditions, the Fuel Handling Accident (FSAR Section 15.3.5) and the Liquid Radwaste Tank Failure (FSAR Section 15.4.14), do not involve a loss of inventory. Therefore, the equipment and instrumentation associated with the Reactor Pressure Vessel WIC TS do not provide detection or mitigation related to these design basis accidents.

The proposed TS LCO 3.5.2 contains requirements for operability of one ECCS subsystem along with requirements to maintain a sufficiently long Drain Time so that plant operators would have time to diagnose and mitigate an unplanned draining event. The NRC staff has determined that new LCOs 3.5.2 and 3.3.5.2 provide for the lowest functional capability or performance levels of equipment required for safe operation of the facility and, therefore, meet the LCO requirements of 10 CFR 50.36(c)(2)(i).

Additionally, the revised TS LCOs 3.5.2 and 3.3.5.2 provide remedial actions to be taken in the event the LCO is not satisfied and, therefore, meet the requirements of 10 CFR 50.36(c)(2)(i).

The NRC staff finds that the proposed Action statements provide reasonable assurance that an unexpected draining event can be prevented or mitigated before the RPV water level would be lowered to the TAF.

The NRC staff evaluated the proposed DRAIN TIME definition; TS 3.5.2, which contains the requirements for RPV WIC; and TS 3.3.5.2, which contains the requirements for instrumentation necessary to support TS 3.5.2. Based on the considerations discussed above, the NRC staff concludes that the proposed revisions are acceptable, because they consolidate and clarify the RPV WIC requirements, which meet 10 CFR 50.36(c)(2)(ii), Criterion 4, to establish LCOs for structures, systems, or components significant to public health and safety as evidenced by operating experience.

The licensee proposed to delete OPDRVs references from certain TS Applicability descriptions, Conditions, Required Actions, and Footnotes statements. The NRC staff has reviewed the proposed changes and determined that the deletion of OPDRVs references, along with the corresponding editorial changes, are appropriate, because the proposed TSs governing RPV WIC and the associated instrumentation, TSs 3.5.2 and 3.3.5.2, respectively, are a clarified and simplified alternative set of controls for ensuring that water level is maintained above the TAF.

The NRC staff reviewed the SRs associated with the new LCOs 3.5.2 and 3.3.5.2. The NRC staff finds that the proposed SRs in TS 3.5.2 are acceptable, since they provide assurance that:

(1) the drain time requirements will be met, (2) sufficient water inventory is available for ECCS injection/spray subsystem RPV injection and pump performance, (3) the ECCS injection/spray subsystems are adequately filled (mitigating the effects of gas accumulation or voiding), (4) the subsystems are properly aligned through verified valve positions to support RPV injection, (5) pumps are verified to be capable of providing adequate flow to support drain time and RPV injection, (6) valves will actuate to the proper position on an automatic isolation signal, and (7) the ECCS injection/spray subsystems can be manually operated to inject. The NRC staff finds that the two SRs proposed for TS 3.3.5.2 are sufficient and acceptable, because they are essential to ensure that the required systems and components are capable of performing their specified safety functions in support of TS 3.5.2, thereby providing protection against a potential drain down of the RPV in Modes 4 and 5. Therefore, the NRC staff concludes that the proposed SRs satisfy 10 CFR 50.36(c)(3).

The NRC staff evaluated the proposed HNP changes against each of the unit applicable design requirements listed in Section 2.3 1 (Unit 1) and Section 2.3.2 (Unit 2) of this SE. The NRC staff finds that the proposed changes for Mode 4 and 5 operations, as they relate to the proposed TS changes for the new DRAIN TIME definition and the removal of OPDRVs references, remain consistent with the applicable design criteria, in that the HNP design requirements are maintained for instrumentation, reactor coolant leakage detection, the reactor coolant pressure boundary, and reactor coolant makeup.

The regulation at 10 CFR 50.36(a)(1) states that a summary statement of the bases or reasons for such specifications, other than those covering administrative controls, shall also be included in the application, but shall not become part of the TSs. In accordance with this requirement, the licensee provided TS Bases changes in the proposed license amendment request (Reference 1). The NRC staff has concluded that the TS Bases changes provided describe the bases for the affected TS and follow the "Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors" (58 Federal Register 39132; July 22, 1993).

Additionally, the proposed TS changes were reviewed for technical clarity and consistency with the existing HNP requirements for customary terminology and formatting. The NRC staff found that the proposed changes were consistent with TSTF-542 (Reference 5), and Chapter 16 of the SRP, NUREG-0800, Revision 3 (Reference 6).

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Georgia State official was notified of the proposed issuance of the amendments on April 11, 2018. The NRC staff verified that the State official had no comments on April 16, 2018.

5.0 ENVIRONMENTAL CONSIDERATION

The amendments change requirements with respect to the installation or use of facility components 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

that the amendments involve no significant hazards consideration, and there has been no public comment on such finding published in the Federal Register on August 29, 2017 (82 FR 41071 ).

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 considerations discussed above, 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.
