Dear Sir or Madam:

By letter dated March 25, 2016, and pursuant to 10 CFR 50.90, Entergy Operations, Inc. (Entergy) submitted a request (Reference 1) for an amendment to the Technical Specifications (TS) for Arkansas Nuclear One, Unit 2 (ANO-2). The proposed change would revise the TSs to

eliminate the Section 6.5, "Inservice Testing Program" (TS Section 5.5 of NUREG 1432, "Standard Technical Specifications - Combustion Engineering Plants," Revision 4, is referred to as TS Section 6.5 in the ANO-2 TSs). A new defined term, "Inservice Testing Program," would be added to the TS Definitions section. The request was consistent with TSTF-545, Revision 3, "TS Inservice Testing Program Removal & Clarify SR Usage Rule Application to Section 5.5 Testing."

During the course of review, the NRC determined that additional information is required to support approval of the Reference 1 request. The request for additional information (RAI) was communicated to Entergy via Reference 2. Attachment 1 to this letter contains Entergy's response to the RAI and Attachment 2 contains program and procedure references.

Page 1 of 5 Response to Request for Additional Information - Adoption of TSTF-545

By letter dated March 25, 2016, and pursuant to 10 CFR 50.90, Entergy Operations, Inc. (Entergy) submitted a request (Reference 1) for an amendment to the Technical Specifications (TS) for Arkansas Nuclear One, Unit 2 (ANO-2). The proposed change would revise the TSs to

eliminate the Section 6.5, "Inservice Testing Program" (TS Section 5.5 of NUREG 1432, "Standard Technical Specifications - Combustion Engineering Plants," Revision 4, is referred to as TS Section 6.5 in the ANO-2 TSs). A new defined term, "Inservice Testing Program," would be added to the TS Definitions section. The request was consistent with TSTF-545, Revision 3, "TS Inservice Testing Program Removal & Clarify SR Usage Rule Application to Section 5.5 Testing."

During the course of review, the NRC determined that additional information is required to support approval of the Reference 1 request. The request for additional information (RAI) was communicated to Entergy via Reference 2. The attachment to this letter contains Entergy's response to the RAI.

The following includes the question presented in the NRC's RAI (Reference 2) followed by Entergy's response.

RAI During the review of the LAR, the NRC staff noted that ANO-2 TS 4.4.1.3.1 states that the required shutdown cooling loop(s) shall be determined OPERABLE per the Inservice Testing Program. In addition, TS 4.9.8.2 states that the required shutdown cooling loops shall be determined OPERABLE per the Inservice Testing Program.

In general, an IST program that fulfills the requirements of Title 10 of the Code of Federal Regulations (10 CFR) Section 50.55a(f) does not contain specific criteria or requirements to verify that systems' loops are operable. Ther efore, the NRC staff request a detailed explanation (including specific testing requirements and acceptance criteria contained in the IST program) as to how these two surveillance requirements assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met.

RESPONSE History IST program references were added to the ANO-2 TSs in 1982 (Reference 3). At the time, the program description was contained in TS 4.0.5. Related TS SRs were updated stating that the component or system required by the respective TS Limiting Condition for Operation (LCO) be "determined to be operable per Specification 4.0.5." This was the terminology included in changes to the subject SRs, 4.4.1.3.1 and 4.9.8.2. This wording matched the wording recommended by the NRC in a letter to all U.S. pressurized water reactor licensees, dated June 11, 1980 (Reference 4).

to 2CAN121601

Page 2 of 5 In 2001, TS Amendment 233 relocated the IST requirements previously contained in TS 4.0.5 to the Administrative Section of the TSs as a program element (Reference 5). This required a change to the subject (and other) SRs in order to replace the words "Specification 4.0.5" with "the Inservice Testing Program." No reduction in program requirements resulted from this relocation.

Entergy concurs that, in general, TS Surveillance Requirements (SRs) today contain specific values, even when referring to the IST program. However, there are examples in the improved standard NUREGs where values are not stated. One example is contained in Revision 4 of NUREG 1432, "Standard Technical Specifications for Combustion Engineering Plants," where only reference to the IST program is included:

SR 3.6.12.1 Verify each vacuum relief line OPERABLE in accordance with the Inservice Testing Program.

System Operation In Modes 1, 2, and 3, the LPSI pump takes suction from the Refueling Water Tank (RWT). The suction is automatically transferred to the Containment Sump when the RWT is depleted. LPSI injects through four separate paths into each of the RCS cold legs upon receipt of an Engineered Safety Features (ESF) signal. The Containment Spray pump also takes suction from the RWT and discharges through the SDC heat exchanger before being sprayed into the

dome region of the Containment Building.

SDC alignment utilizes a LPSI (normal) or CS (alternate) pump taking suction from the "B" RCS hot leg and discharging through the Service Water cooled SDC heat exchanger before the fluid is returned to the RCS via the four normal LPSI injection paths.

Page 3 of 5 Current Program Requirements The subject SRs are associated with verification of Shutdown Cooling (SDC) loop operability in shutdown Modes 4, 5, and 6. As stated previously, both SRs point to the IST program to demonstrate operability. Operability of a SDC loop requires the capability to establish a minimum recirculation flow to ensure decay heat can be removed from the reactor. The definition of operability in the TSs states that necessary supporting equipment must also be operable. In order for the SDC loop to perform its intended function, supporting features would include a cooling medium (in this case, Service Water available to the SDC heat exchanger) and electrical power to the SDC pump. The SDC pump is normally the Low Pressure Safety Injection (LPSI) pump, although under low Reactor Coolant System (RCS) pressure conditions, a Containment Spray (CS) pump can be utilized as a SDC pump. Because SDC operations are not associated with Design Basis Accidents (DBAs), the system operability requirements are much reduced from that required of the LPSI pumps in Modes 1, 2, and 3 (with RCS pressure > 1700 psia) or the CS pumps in Modes 1, 2, and 3.

The ANO-2 IST program is controlled by SEP-ANO-2-IST-2, "ANO Unit 2 IST Plan." The IST Plan is designed to contain the information necessary to identify the pumps and valves subject to IST, categorization of components, identification of tests to be performed and the frequencies of those tests. It also provides relief requests, justifications for cold shutdown and refueling testing, and positions taken with respect to the prescribed testing in 10 CFR 50.55a. The ANO Unit 2 IST Plan is just one part of the Entergy IST Program. The IST Plan is controlled and implemented in accordance with Entergy fleet procedures EN-DC-332, "Inservice Testing" and EN-DC-174, "Engineering Program Sections." For the ANO Unit 2 IST Plan, the applicable Code is the ASME OM Code 2004 Edition with no addenda.

ANO-2 is in its 4 th 120-month IST interval (March 26, 2010 through March 25, 2020). This IST Plan was provided to the NRC in letter dated March 25, 2010 (Reference 6) which included a relief request associated with the LPSI pumps:

LPSI Pump Group Classification - The LPSI pumps will be tested as stand-by pumps (Group B) during Modes 1-4 and continuously or routinely operated pumps (Group A) during Modes 5-6.

This relief request (PRR-ANO2-2009-1) was approved for the ANO-2 4 th 120-month interval in NRC letter dated October 10, 2009 (Reference 7).

Although system requirements are greatly reduced for SDC, the IST program does not differentiate between the system's modes of operation with respect to testing. LPSI system testing is addressed in OP-2104.040, "LSPI System Operation," which includes quarterly and refueling outage testing requirements. The system is tested to ensure the LPSI system meets the full requirements for ESF actuation and DBA mitigation. The quarterly test and outage-related full flow test refer directly to the IST program which ensures testing methods and criteria are not revised without first verifying IST program requirements will continue to be met.

The LPSI quarterly tests are split into separate supplements to account for the different system alignments when aligned for LPSI and when aligned for SDC. Either supplement verifies proper oil levels, pump cooling, room cooling, pump head, and operation of the discharge check valve. Pump/component leakage is also documented, if any. System automatic valves are also stroke to 2CAN121601

Page 4 of 5 tested and timed every quarter, along with verifying proper operation of other check valves in the system. Supplement 6 of the procedure also tests the Automatic Closure Interlock designed to prevent over-pressurization of the LPSI/SDC piping (verifies respective suction valves from the "B" RCS hot leg automatic close on simulated high RCS pressure signal).

The full flow tests, besides verifying ESF required flow, records much of the same data and verifies acceptable vibration levels at full flow conditions. The test also verifies proper operation of other check valves in the system. The ESF flow requirements are much more stringent than the flow requirements needed for SDC. The minimum SDC flow requirement is required by SDC TS SR 4.9.8.1 in Mode 6:

A shutdown cooling loop shall be determined to be in operation and circulating reactor coolant at a flow rate of 2000 gpm at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

The associated TS Bases states:

The requirement that at least one shutdown cooling loop be in operation ensures that (1) sufficient cooling capacity is available to remove decay heat and maintain the water in the reactor pressure vessel below 140 °F as required during the REFUELING MODE, and (2) sufficient coolant circulation is maintained through the reactor core to minimize the effects of a boron dilution incident and prevent boron stratification.

In other modes of operation where SDC may be in service, no specific flow requirements are stated in the TSs, although the system must be capable of removing the decay heat load for the given time in core life and time after shutdown. Procedures instruct operators to maintain a flow of at least 2000 gpm. OP-2104.004, "Shutdown Cooling System," provides operators guidance for initial flow based on historical operations. The procedure recommends a total initial flow of approximately 4000 gpm, with approximately 1500 gpm of this flow passing through the SDC heat exchanger (i.e., only 1500 gpm is expected to be needed to remove decay heat).

The CS pump, although rarely utilized for SDC, is also tested as if required for ESF standby in accordance with procedure OP-2014.005, "Containment Spray," similar to the LPSI pump. As shown in the above simplified diagram, the CS pump recirculates water using the LPSI injection paths. OP-2104.004 provides guidance for using either the LPSI or CS pump for SDC operations.

System procedures also provide detailed guidance with respect to proper system venting to ensure concerns stated in Generic Letter 2008-01, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems," are appropriately addressed.

Summary The ANO-2 IST test requirements for the SDC system are well beyond those required by the standard TSs. For SDC, NUREG 1432, Revision 4, requires verification that a train is in service with no stated flow criteria and verification of proper breaker alignment (to ensure both trains remain available), with the exception of standard TS 3.9.4 (SDC - High Water Level), which states a bracketed (site-specific) minimum flow requirement. to 2CAN121601

Page 5 of 5 In addition, the requested adoption of TSTF-545 does not change any IST or code program requirement. The change to the subject ANO-2 SRs only capitalized the terms "INSERVICE TESTING PROGRAM" since all TS defined terms are required to be capitalized throughout the TSs. No change to the actual testing requirements for either SR has been proposed.

Based on the testing of SDC system components performed in accordance with the ANO Unit 2 IST program described above, which far exceed the SRs contained in standard TSs, the ANO program effectively ensures SDC operability for the various required modes of operation. Therefore, Entergy believes the proposed changes to the subject SRs are acceptable and meet the intent of TSTF-545.

PAGE: 11 OF 17 PUMP RELIEF REQUESTS (PRR) 10 CFR 50.55a Request Number PRR-ANO2-2009-1 REASON FOR

RELIEF REQUEST: (cont:) The ANO-2 LPSI pumps (and motors) are located in areas which are both radiation areas and contamination areas. Dose rates for these locations vary depending upon the current location of radiological hot spots. This results in ALARA issues as well as contamination control issues to obtain quarterly vibration data.

In addition to the areas being radiological concerns, the areas are also difficult to access and require the use of a ladder to access the top of the LPSI pump motors to monitor upper motor vibration as required on a quarterly basis for Group A vertical line shaft pumps. Personnel safety is compromised because personnel must lean from the ladder to access the upper motor vibration points, resulting in personnel safety issues to acquire this vibration data.

On this basis, we feel that an acceptable level of quality and nuclear safety is still maintained while many of the burdens, costs and concerns associated with quarterly vibration testing, including both ALARA and personnel safety issues, would be eliminated by categorizing the ANO-2 LPSI pumps as Category B during Modes 1-4, and as Category A during Modes 5-6 as was approved for the Calvert Cliffs Nuclear Power Plant by Safety Evaluation dated June 18, 2008.

With the LPSI pumps categorized as Group B during Modes 1-4, the two minute minimum pump run time for quarterly tests is also eliminated.

Elimination of the minimum pump run time requirement and the requirement to record vibration levels will reduce the pump run time required for each quarterly test. This will help reduce the cumulative run time for each LPSI pump under low flow conditions to support testing, with a commensurate reduction in pump wear.

PROPOSED ALTERNATIVE AND BASIS: Perform inservice testing of the LPSI Pumps per the 2004 Edition of the OM Code Subsection ISTB, "Inservice Testing of Pumps in Light-Water Reactor Power Plants," with the following modifications:

LPSI Pump Group Classification - The LPSI pumps will be tested as stand-by pumps (Group B) during Modes 1-4 and continuously or routinely operated pumps (Group A) during Modes 5-6.

Based upon the determination that the proposed alternative to the ASME OM Code-2004 Edition requirements would provide an acceptable level of quality and safety, it is requested that the alternative be granted pursuant to 10 CFR 50.55a(a)(3)(i).

2104.004 SHUTDOWN COOLING SYSTEM PAGE: 5 of 149 CHANGE: 058 5.0 LIMITS AND PRECAUTIONS

5.1 Maximum LPSI and SDC System suction piping temperature is 300°F.

5.2 Auxiliary Building radiation levels can change during alignment for different Shutdown Cooling System evolutions (i.e. placing SDC in service, removing SDC from service, modifying SDC purification flow, swapping SDC trains, etc.). (CR-AN0-2-1998-0469)

5.3 Containment Spray pumps operating on SDC require SDC suction pressure to be maintained less than 50 psig at 2PIS-5088 to prevent over pressurization of Containment Sump/RWT suction piping.

5.4 The maximum SDC suction pressure for LPSI Pump Suction Pressure transmitters 2PT-5039 and 2PT-5058 is 50 psig.

5.5 SDC pump Motor starts are limited to two starts in succession from ambient or one start from rated temperature. For subsequent starts, allow 30 minutes run time or 60 minutes idle time.

5.6 RCS level less than 65 inches above bottom of hot leg require operating only one SDC pump at a time to prevent high flow rates and subsequent vortexing. (Two pumps may be in operation while shifting SDC pumps.)

5.7 Minimum SDC flow of 2000 gpm must be maintained except as allowed by Tech Specs. Instrument inaccuracies are not included due to large conservative margins in Tech Spec Bases. (CR-ANO-2-1998-0230)

5.8 In Mode 5, SDC flow may be stopped for up to one hour provided:

No operations permitted that could cause RCS dilution.

Core outlet temperature Margin to Sat maintained at greater than or equal to 10°F.

5.9 In Mode 6, SDC flow may be stopped for up to one hour every eight hours during performance of Core Alterations, otherwise refer to TS 3.9.8.1.

5.10 Service Water flow through SDC Heat Exchangers (2E-35A/B) must be established before initially placing SDC in service.

5.11 If LPSI Pump Discharge temperature (T5096) less than 198°F, Service Water flow through heat exchanger may be secured as necessary to limit cooldown or to allow slow heatup to 198°F (T5096).

5.12 LPSI Pump Discharge temperature (T5096) limit of 198°F is based on SDC HX Service Water outlet piping design temperature limit of 198°F.

5.13 If SDC HX SW flow isolated with RCS aligned, SW is reintroduced slowly to limit thermal stresses by maintaining cooldown rate less than 8°F/minute to prevent exceeding SDC HX cooldown limit of 520°F/hr.

2104.004 SHUTDOWN COOLING SYSTEM PAGE: 20 of 149 CHANGE: 058 8.14 IF desired to place BOTH LPSI pumps in service for SDC, THEN PLACE the second LPSI pump in service per "Operation of LPSI Pumps/SDC HXs in Parallel for Shutdown Cooling" section of this procedure.

NOTE With low Service Water temperatures, lowering Service Water flow to the in-service SDC Heat Exchanger allows better control of SDC Temperat ure Control Valve (2CV-5093). For example, during the fall forced outage of 2013, SW flow was throttled to 1200 gpm which sent more flow through 2CV-5093 allowing better SDC temperature control.

8.15 IF desired to lower Service Water flow to the in-service SDC HX, THEN PERFORM "Service Water Operation Through SDC HX" section of this procedure.

8.16 ENSURE SDC HX Tube Side flow (F5610/F5616) within the following limits:

Acceptable limits of Attachment K, S DC Heat Exchanger RCS Flow Limit Curves with RCS Tc greater than or equal to 239°F but less than or equal to 300°F Less than 5320 gpm with RCS Tc less than 239°F NOTE Historical data indicates total flow should be adjusted to 4,000 gpm with 1,500 gpm through the SDC HX, and then adjusted to maximize cooldown rate within Tech Spec limits (goal is 90°F/hour). Remaining steps may be performed in any order.

CRITICAL STEP 8.17 COMMENCE raising SDC Heat Exchanger flow using Hx Return Flow (2HIC-5093) to maintain RCS cooldown rate within limits of TS 3.4.9.1.

8.18 ENSURE the following on LPSI Discharge Header Flow controller (2FIC-5091):

SDC Flow (F5610/F5616) in Acceptable Region of 2103.011, Exhibit 1, SDC Vortex Curve High alarm setpoint within 300 gpm of actual flow (preferred) or as close as possible to actual flow if alarm setpoint cannot be adjusted to within 300 gpm Low alarm setpoint within 300 gpm of actual flow (preferred) or as close as possible to actual flow if alarm setpoint cannot be adjusted to within 300 gpm Low alarm setpoint greater than 2100 gpm
