Response to Draft Request for Additional Information License Amendment Request Regarding Leak Detection System Technical Specification Setpoint, Allowable Value and Design Basis Changes In the Reference 1 letter, Exelon Generation Company, LLC (Exelon) requested changes that would modify Technical Specification (TS) TS Table 3.3.2-2, "Isolation Actuation Instrumentation Setpoints, 11 for the Reactor Water Cleanup System, High Pressure Coolant Injection System and Reactor Core Isolation Cooling System rooms and to modify the design basis for the leak detection limit for the Turbine Enclosure-Main Steam Line Tunnel area. The NRC reviewed the license amendment request and identified the need for additional information in order to complete their evaluation of the amendment request. A draft request for additional information (RAI) was electronically transmitted to Exelon on July 29, 2014 (Reference 2). The questions are restated below along with Exelon's response.

SCVB-RAl-1 Question: 25 gpm Leak to the application dated December 6, 2013, refers to the design basis 25 gallon per minute (gpm) leak in a number of places as a "steam leak." In the last paragraph on page 6 of Attachment 1 to the application, the licensee states that the equivalent leakage from a 25-gpm leak is calculated as 3.33 pounds mass per second (lbm/sec) (i.e., based on liquid water density).

It appears that the 25 gpm leak is considered as pure steam but with liquid density. In this case, the mass and energy used for the calculation of room heat up would be unrealistically high and non-conservative for a leak detection setpoint. Please justify the appropriateness of the assumptions.

Provide the mass flow rate (lbm/sec) and flow enthalpy of the leak as well as the pressure and temperature for the leak source for all cases used in the leak detection Calculation-1001 Revision 5.

Response

The leak is considered to be a steam leak that would result in a liquid equivalent of 25 gpm if collected in a sump. The mass and energy are not unrealistically high and non-conservative for a leak detection isolation setpoint. This methodology is consistent with the methodology applied in the General Electric "Design Guide for Detection of Small Steam Leak," dated February 1969.

For clarification, the steam leak detection system typically has two setpoints:

a) An alarm setpoint set nominally to detect leakage equivalent to 5-gpm water equivalent (may be set higher in large compartments or compartments with large heating I ventilation I air conditioning (HVAC) flows) b) An automatic isolation setpoint, nominally set to detect and isolate the steam supply at a leak of 25-gpm water equivalent.

The alarm setpoints are not TS values. The isolation setpoints are contained in the TSs. The setpoints contained in the license amendment request are isolation setpoints.

Response to Draft Request for Additional Information License Amendment Request Regarding Leak Detection System Technical Specification Setpoint, Allowable Value and Design Basis Changes Page 2 The mass flow rate and flow enthalpy, as well as the pressure and temperature for the leak sources, are provided below:

Mass Flow rate (5 gpm) = 0.666 lbm/sec Mass Flow rate (25 gpm) = 3.33 lbm/sec Room Enthalpy Break Pressure Break Temperature Outboard MSIV room 1190.9 BTU/lbm 1053 psig 553°F Penetration Compartment 1190.9 BTU/lbm 1053 psig 553°F RWCU Pump Room 530.3 BTU/lbm 1053 psig 535°F RWCU Regen HX Room 417.4 BTU/lbm 1168 psig 438°F RWCU non-Regen HX Room 208.0 BTU/lbm 1213 psig 237°F HPCI Pump Room 1190.9 BTU/lbm 1053 psig 553°F RCIC Pump Room 1190.9 BTU/lbm 1053 psig 553°F Turbine Enclosure - Main Steam 1190.9 BTU/lbm 1053 psig 553°F Tunnel The leak source for the Outboard MSIV room, Penetration compartment, HPCI Pump room, RCIC Pump room and Turbine Enclosure Main Steam Tunnel is the Main Steam system. The leakage source for the RWCU pump room, RWCU Regen HX room and RWCU non-Regen HX room is fluid at various points in the Reactor Water Cleanup System.

SCVB-RAl-2 Question: Analysis Conditions In the graphs presented in Attachment 3 to the application, the low room temperature reflecting winter conditions has been taken into account as an initial condition in the room temperature calculation. However, it is not clear if the winter temperature has also been used as a boundary condition in that the surrounding and/or extended rooms are subject to a cold environment where the winter temperature should be applied as boundary condition. Furthermore, it is not known if the internal structures (if existing) in the room have been modeled as heat sink that will also lower the room temperature.

Have the cold ambient temperature, heat sinks, and associated steam condensation been considered in the calculation? If not, justify why. In addition, have factors, other than weather conditions that will potentially affect the room temperature, also been considered and evaluated to assure the leak detection system's detectability (e.g., cooler operation, ventilation system changes, opening a new flow path or increasing flow area from the room to the other rooms)?

Response

In all winter cases, surrounding or adjacent compartments are modeled as separate compartments at winter temperatures, or as a constant winter room temperature applied on the external wall of the compartment of interest. In all cases, ventilation flows are modeled, as are room coolers in the compartment of interest. Condensation on external walls is accounted for by the use of a 4x Uchida condensing film heat transfer coefficient applied to external walls I floors, etc. If the room is equipped with blowout panels, they were included in the model. In large compartments, internal heat sinks were modeled. In small compartments, the internal heat sinks were not modeled, because the room temperature rise occurs in too short of a time

Response to Draft Request for Additional Information License Amendment Request Regarding Leak Detection System Technical Specification Setpoint, Allowable Value and Design Basis Changes Page 3 frame for internal heat sinks to react. In these cases, the room air volume was reduced to account for the volume of internal heat sinks.

SCVB-RAl-3 Question: Licensing Design Basis of Leak Rate to Determine Leak Detectability Raising the leak detection alarm limit to 35 gpm reduces the time an operator has to isolate the leak before the conditions become hazardous. Please provide and evaluate the proposed 35 gpm leak against the original design basis for leakage detection capability as specified in General Electric design specifications (discussed in the second paragraph on page 6 of ). Otherwise, address the concerns as described above.

Response

The alarm limit is not being raised to 35 gpm. This leakage limit design basis change of 35 gpm is for the automatic isolation setpoint. The corresponding TS isolation setpoint of 165°F will remain at its current value. Alarm setpoints are not included in TSs. In most compartments, the alarms setpoints correspond to a 5-gpm leak. However, in very large compartments, or compartments with large HVAC flows, the alarm setpoint corresponds to higher leak rates to allow the leak detection setpoint to differentiate between winter steam leaks and normal summer operating temperatures. The alarm limit for the Turbine Enclosure - Main Steam Line Tunnel area is 155°F which would correspond to approximately 11-gpm leak for summer conditions and an 18-gpm leak for winter conditions.

The current normal isolation setpoint is based on a 25 gpm equivalent leak. The Turbine Enclosure - Main Steam Line Tunnel area is contained in the Main Condenser compartment of the turbine building, which is a locked high radiation area during normal operations.

Additionally, the main steam lines are located near the ceiling of this compartment.

Therefore, raising the leakage limit design basis for the isolation setpoint to correspond from a 25-gpm to a 35-gpm leak for the Turbine Enclosure - Main Steam Line Tunnel area does not reduce the time an operator has to isolate the leak because the alarm limit is not being changed.

SCVB-RAl-4 Question: Leak Detection vs. Leak Source Please describe the location of the leak detection instrument in relation to possible sources of leakage (i.e. distance).

Response

The leak detection instruments are nominally installed three feet or less above the steam lines of interest. The distance between detectors varies based on the size of the compartment and length of line being monitored.

Response to Draft Request for Additional Information License Amendment Request Regarding Leak Detection System Technical Specification Setpoint, Allowable Value and Design Basis Changes SCVB-RAl-5 Question: Calculation and Supporting Documents Page 4 To facilitate the review, please submit Calculation-1001 (Attachment 1, Section 6.0, Reference 2) and its major supporting references or documents.

Response

Calculation -1001 is 225 pages with 538 reference documents. It would not be practical to submit the calculation and the major references. However, we have attached the sections detailing the modelling of the Turbine Enclosure, Main Steam Tunnel (Condenser Area). See to this letter.

EICB-RAl-1 Question: Turbine Enclosure Main Steam Line Tunnel Design Basis Change As discussed on page 6 of Attachment 1 to the application, the licensee proposes to change the design basis from a 25-gpm to a 35-gpm equivalent steam leak during winter operations for the turbine enclosure main steam line (MSL) tunnel. The calculated temperature response curve for a 25-gpm leak in this area was provided in Attachment 3 to the application, however, the temperature response curve was not provided for the 35-gpm leak. Please provide the temperature response curve and description of "Turbine Enclosure MSL Tunnel Steam Leak" with a 35-gpm equivalent steam leak. In addition, please provide the current analytical limit (AL) as well as the proposed new AL values.

Response

The 35-gpm leakage winter temperature response curve is contained in Attachment 3 to this letter. A summer temperature response curve for a 35-gpm leak was not developed because a 25-gpm leak reaches the isolation setpoint.

The current analytical limit for the Turbine Enclosure Main Steam Leak detection Isolation setpoint is 178°F. This value is identical to the proposed analytical limit. This license amendment request does not request a change to the current corresponding TS setpoint of 165°F. The only change requested is to the licensing basis for the TS setpoint of 165°F.

EICB-RAl-2 Question: Accuracy and Drift Section 3.0 of Attachment 1 to the application indicates that the setpoint methodologr for Limerick is based, in part, on General Electric (GE) Topical Report NEDC-31366P-A, "General Electric Instrument Setpoint Methodology 11 dated September 1996.

1 GE topical report NEDC-31336P-A is a non-public, proprietary version of the GE setpoint methodology (ADAMS Accession No. ML072950103). A public version of the methodology is available as GE topical report NED0-31336-A (ADAMS Accession No. ML073450560).

Response to Draft Request for Additional Information License Amendment Request Regarding Leak Detection System Technical Specification Setpoint, Allowable Value and Design Basis Changes Page 5 Section 4.4, 11NRC Open Item 5.4 - Expanding Manufacturers Performance Specifications" in topical report NEDC-31366P-A discusses the results of a GE evaluation of field data on performance of Rosemount transmitters and trip units in relation to the design assumptions for drift contained in Sections 1.0 and 2.0 of the topical report. Section 2 of the topical report provides the methodology used by GE to validate instrument accuracy and drift values against system requirements. As stated in Section 2.1 of the topical report, the accuracy and drift methodology is based on the use of Rosemount ( 1151, 1152-T0280, 1153 Series B, 1154) or Gould (3018, 3200, 3218) transmitters with Rosemount (510) trip units.

Page 9 of the NRC staff's safety evaluation (SE) for topical report NEDC-31336P-A provides an evaluation of the information in Section 4.4 of the topical report. The staff stated, in part, that:

Where instruments are used that are different from those presented in Section 2 of NEDC-31336, the licensee must demonstrate that instrument performance can be quantified either through vendor data or plant specific surveillance test data.

The licensee must confirm that the observed measurements of instrument performance are bounded by the design allowances used in the plant specific analysis, for the chosen calibration interval, in accordance with the criteria stated in NEDC-31366.

The NRC staff notes that the specific line break detection applications that are the subject of this amendment request are not covered among the 25 specific instrument setpoint descriptions discussed in Section 3.0 of NEDC-31366P-A. In addition, the temperature elements and temperature indicating switches in the instrument loops, associated with this amendment request, are of different manufacturers and model numbers than those contained in Section 2 of NEDC. Please provide information to demonstrate that the instrument accuracy and drift values, for the temperature elements and temperature indicating switches are bounded by the design allowances used in the plant-specific analysis, for the chosen calibration intervals, consistent with the criteria stated in NEDC-31366P-A.

Response

The instrument loops that are the subject of this amendment request include temperature elements and temperature-indicating switches. The temperature elements are manufactured by Pyco with Model Number 102-9039 and the temperature switches are NU MAC manufactured by GE with model number 304A3714. The surveillance testing for the NUMAC instrument channels as listed below are performed every 24 months. Based on the review of instrumentation performance trending for the past five operating cycles (10 years), there were no indications of unsatisfactory surveillance testing results for the two-year calibration interval.

Instrument channel test results verified that channel performance was within 1 % and bounded by the value utilized in the plant specific analysis.

Furthermore, the temperature elements are safety related and environmentally qualified components. The temperature elements demonstrated through the qualification testing that the component remained within the limits of error of +/-1°C or +/-0. 75% per the specification which is the overall device accuracy used in the setpoint calculations.

Response to Draft Request for Additional Information License Amendment Request Regarding Leak Detection System Technical Specification Setpoint, Allowable Value and Design Basis Changes Page 6 Therefore, the instrument accuracy and drift values for the temperature elements and temperature indicating switches are bounded by the design allowances used in the plant-specific analysis.

EICB-RAl-3 Question: Temperature and Humidity Environmental Conditions The temperature elements, associated with the proposed amendment, will be subjected to elevated temperature and humidity environmental conditions during the timeframe in which they are required to perform their leak detection functions. Attachment 4 to the application provides the instrument loop uncertainty calculation for the associated instrument loops.

Section 6.2.7 of the calculation lists the 11Device Accuracy Temperature 11 uncertainty 11ATE 11 value for the temperature elements as being 0.00000. Section 6.2.8 lists the 11Device Humidity 11 uncertainty 11HE 11 value as 0.00000. The calculation states that the temperature and humidity effects are based on vendor specifications.

Please confirm that under the elevated temperature and humidity conditions that will be present when the instrument channel must be available to perform its required functions, the instrument performance is enveloped within the vendor's stated accuracy effects (e.g., calculation Section 6.2.1 ), including the performance effects of the instruments under steam and degraded insulation resistance.

Response

The temperature elements associated with this amendment request are safety-related components and located in harsh environment (Environment Qualification - EQ components).

The components manufactured by Pyco with Model Number 102-9039 are qualified as an EQ component at Limerick by EQ binder P-300. Based on the qualification report, accelerated thermal aging at elevated temperature, radiation exposure, and LOCA simulation were performed to demonstrate the qualification of the components. The qualification testing concluded that the components remained within the limits of error of +/-1°C or +/-0.75% per the specification.

In summary, the Device Accuracy Temperature and Device Humidity uncertainties as specified in Sections 6.2. 7 and 6.2.8 of the calculations are included as part of the overall device I component accuracy or enveloped within the overall accuracy of +/-1°C or +/-0.75%.

REVISION:

5 Piping Heat loads are modeled directly in CFLUD. Since the RCIC turbine is not running in theses cases, only two lines are considered. The RCIC Turbine steam supply line and the steam trap in the RCIC steam supply are modeled as follows:

RCIC Turbine Steam Supply: 6" EBB-109(209) (Ref. 4.17)- This line is modeled up to HV-50-1 (2)F045 using length dimensions from ref. 4.16 below El. 217'-0", Pipe diameter, wall thickness and Insulation thickness data is given from Ref. 4.1. Insulation thermal conductivity and surface emissivity are taken from Cale LM-400.

Pipe Length= 76.06 ft (Below 201 '=0" - RCIC Pump Room)

= 24.31 ft (Between El. 217'-0" and 201 '-0" - RCIC Piping Area)

Steam Trap : The steam trap is modeled as a 19" long piece of un-insulated 12" pipe using diameter and wall thickness data for EBB-109. The length dimension is from Ref. 4.16.

Piping Temperature and Pressure (for steam leaks)= 553°F, 1053 psig (Ref. 4.1 EBB-109 Line Class)

Minimum Normal Temperature= 65°F (Ref 4.2, page 14)

Both Supply Air and Exhaust are Ducted.

6.9 Turbine Enclosure -Main Steam Tunnel (Condenser Area)

The Condenser Area was modeled in CFLUD using inputs described on the following pages:

Total Room Volume= 31,254.5 ft3 (Attachment 2, page 94)

Since CFLUD calculates bulk average room temperatures, the steam leak detection setpoint in large compartments or where room coolers are present may be more properly modeled as a spherical compartment with a radius of the distance between temperature elements.

Distance between temperature elements = 16'-7" (Ref. 4.537)

The break volume modeled would be a sphere with radius 16.58 ft.

Volume used in calculation= (4/3) *Pl() *(16.58)3 = 19103 ft3 Since only the compartment ceiling and a portion of the slab at El 253 '-0" are in the break area, all other heat sinks were removed from the model.

REVISION:

5 Since some of the temperature elements may be affected by the discharge of a fan cooler, one cooler is modeled in this volume. This includes the motor heat load. The cooler is modeled as HV AC into the break area at the discharge temperature of the cooler. The cooler outlet temperature is determined by running the entire CFLUD model starting at 65°F with a 25 gpm break and inspecting the output at the maximum compartment temperature. The cooler outlet temperature used in the break model is 78.2 Fat 87.7% relative humidity (See Attachment 4 page )

Since two main steam lines are fully contained in this break zone, the heat loads from 66ft of main steam line is included (2 x 33 ft each line).

Heat Load (Full Compartment)= 1197257.6 BTU/hr (Attachment 2 page 102)

Heat Load (Break Zone) = 9425 BTU/hr (Attachment 2, page 101) (Motor heat from Unit Cooler 2A V-138)

Piping Temperature and Pressure (for steam leaks)= 553°F, 1053 psig (Ref. 4.1 EBB-103 Line Class)

Minimum Normal Temperature (Surrounding Area)= 65°F (Ref 4.2, page 14)

Minimum Normal Temperature (Condenser Area) is calculated by setting the starting temperatures in the CFLUD model at 65°F and running the model with normal heat loads but no steam leak to determine the starting temperature for the leak analysis. This temperature is then compared to historical data from ST-6-107-590-1(2) (References 4.26 and 4.27) to verify that results are conservative for actual observed temps. (See Attachment 4 for results of this analysis. The starting temperature used for winter steam leak detection cases is 92.7°F.

Maximum Normal Temperature= 125°F (Ref. 4.2, page 14)

16329 cfm Supply Air is by infiltration from the turbine building. Exhaust is Ducted.

Since there are no registers in the area of the temperature elements, HV AC, other than the effect from the room cooler is deleted from the break zone model.

5 Volume of Turbine Building Pipe Tunnel: The Turbine Building Pipe Tunnel is the Area between Elevation 239'-0" and the bottom of the El 269'-0" slab between Column's N and K between the Feedwater Heater compartments and between Columns N and Me in front of the feedwater heater compartments as well as the volume between El. 255'-3" and the bottom of the El 269'-0" slab over the feedwater heater compartments. This volume is bounded on the East by Wall at Column Line 41 and on the West by the wall at Column line 26.6 (See Ref.

4.32, 4.33, 4.34 and 4.35) This volume communicates directly with the condenser bay and will be included in the condenser bay volume.

This volume will be computed in several parts:

Part 1: This represents the volume between elevations 239'-0" and the Bottom of the El 269'-0" slab bounded on the west by the Wall at Column 28 and on the east by the wall at Column 38.

It is bounded on the North by the curb 1 '-0" North of Column N and on the South by the South Edge of the wall at Column N. (See Ref. 4.33 and 4.34)

Height= 269'-0"-1 '-3" -239'-0" = 28'-9" or 28.75 ft (see Ref. 4.30 and 4.35)

Width = 2'-0" + 1 '-0" = 3.0 ft (See Ref. 4.33)

Length= 18'-0" x 10-1'-10%" - 1'-9" = 176'-4%" or 176.375 ft (See ref. 4.33 and 4.34)

Volume (Part 1) = 15212.3 ft3 Part 2: This represents the volume between elevations 239'-0" and the Bottom of the El 269'-0" slab bounded on the West by the Column Line 41, on the North by the South face of the wall at Column N and on the South by the North face of the wall at Column K.

Height = 28. 75 ft Width= 26'-0"+ 23'-0" -2'-0" -1'-7Y2" = 46'-4Y2" or 46.325 ft (Ref. 4.33)

Length = 18'-0" x 13+ 6'-0" +9'-0" = 249'-0" {See Ref. 4.33 and 4.34)

Volume (Part 2) = 331629.09 ft3 Part 3: This represents the volume of the feedwater heater compartments containing the "B" and "C" heater strings, between Elevation 239'-0" and El 255'-3" {Ref. 4.32). This volume will be subtracted from the Volume of the Pipe Tunnel. This area is bounded on the West by the Wall located 6" west of column 28.6, on the East by the wall located 8'-6" West of Column 36, on the North by the wall located at column Me and on the South by the wall located at Column K.

5 The CFLUD computer code has a feature which allows piping heat loads to be modeled directly in the code inputs. Data required is as follows (see Ref. 4.531 ):

1. Compartment number containing hot pipe.

2. Pipe Temperature (°F) (Ref. 4.1)

3. Pipe Outer Dia. (in.)

4. Pipe Length (ft.)

5. Insulation Thickness (in.)

6. Insulation Thermal Conductivity (BTU/hr.-ft.-°F)

7. Forced Convection Heat Transfer Coeffici~nt (BTU/hr.-tt2-°F)

8. Natural Convective Coefficient (BTU/hr.-fr"-°F-°Fm)

9. Natural Convective Exponent (nl)

10. Radiative Coefficient (BTU/hr.-fr-0 R4)

Small piping has been ignored for the purposes of this analysis.

Piping data used in this calculation is as follows:

Insulation Thickness:

Insulation thicknesses are given in Ref. 4.535.

Insulation Thermal Conductivity:

Insulation thermal conductivities are given in Ref. 4.529.

Forced Convection Coefficient:

Forced convection is not modeled. Zero values are used in this model.

Natural Convective Coefficient and Exponent: Values for the natural convective coefficient and exponent are found in Ref. 4.531.

Radiative Coefficient:

The radiative coefficient is calculated from the equation:

hrat1 = aeF where: a=

E=

F=

Stefan-Boltzman Constant (0. 714x10-8 BTU/hr-ft2-R4) surface radiative emissivity radiation shape factor (1.0 for pipes)
