1.0 INTRODUCTION

This calculation updates the Nine Mile Point, Unit I (NMP-1) pressure-temperature (P-T) curves for the beltline, bottom head, and non-beltline (feedwater nozzle / upper vessel) regions. The P-T curves are created for 28, 36, and 46 effective full power years (EFPY) of operation, and are developed using the methodology of the 2001 Edition, 2003 Addenda of ASME Code,Section XI, Appendix G [1], and IOCFR50 Appendix G [2]. This calculation has been developed in accordance with the methodology of the Boiling Water Reactor Owner's Group (BWROG) Licensing Topical Report, "Pressure-Temperature Limits Report Methodology for Boiling Water Reactors" [3].

2.0 METHODOLOGY A full set of P-T curves are computed, including the following plant conditions: Operating Pressure (Leak) Test (Curve A), Normal Operation - Core Not Critical (Curve B), and Normal Operation - Core Critical (Curve C). The curves are consolidated into three bounding evaluation regions of the reactor pressure vessel (RPV): (1) the beltline, (2) the bottom head, and (3) the feedwater nozzle / upper vessel.

The primary methodology for calculating P-T curves is described in Reference [3]. Therefore, all methodology in this section is obtained from Reference [3] unless otherwise noted. The P-T curves are calculated by means of an iterative procedure, in which the following steps are completed:

Step 1: A fluid temperature, T, is assumed. The P-T curves are calculated under the premise of an assumed flaw that has extended 1/4of the way through the vessel wall. According to Reference [3], the temperature at the assumed flaw tip, T1 / 4, is conservatively treated as equal to the assumed fluid temperature.

Step 2: The static fracture toughness factor, K1,, is computed using the following equation:

Klc = 20.734 - e°2(T-ART) + 33.2 (1)

Where: Ki, = the lower-bound static fracture toughness factor (ksi'Iin).

T the metal temperature at the tip of the postulated 1/4through-wall flaw ( 0F), as described above.

ART = the Adjusted Reference Temperature (ART) for the limiting material in the RPV region under consideration (°F)

File No.: 0800297.301 Page 4 of 47 Revision: I F0306-OIRO

StructuralIntegrity Associates, Inc.

Step 3: The allowable stress intensity factor due to pressure, Kip, is calculated as:

=Ki- SFK (2)

Where: Kip = the allowable stress intensity factor due to membrane (pressure) stress (ksi/in).

Kj,: = the lower-bound static fracture toughness factor calculated in Equation 1 (ksi*/in).

Kit = the thermalstress intensity factor (ksi'lin).

SF = the safety factor, based on the reactor condition.

Note: For hydrostatic and leak test conditions (i.e., P-T Curve A), the SF = 1.5. For normal operation, for both a non-critical and a critical reactor (i.e., P-T Curves B and C), the SF =

2.0. When calculating values for Curve A, the thermal stress intensity factor is neglected (Kit

= 0), since the hydrostatic leak test is performed at or near isothermal conditions (typically, the rate of temperature change is 25°F/hr or less) [3].

For Curve B and Curve C calculations, Kit is computed in different ways based on the evaluation region. For the beltline and bottom head regions, Kit is determined using the following equation based on the ASME Section XI, Nonmandatory Appendix G method:

Kit = 0.953 X10-3 _CR- t2.5 (3)

Where: CR = the cooldown rate of the vessel (°F/hr).

t = the RPV wall thickness, unique for each region (in).

For the feedwater nozzle / upper vessel region, Kit is obtained from the stress distribution output of a finite element model (FEM) of the feedwater nozzle, which is the limiting non-beltline component from a stress point-of-view (neglecting the flange, which is separately covered by application of 10 CFR 50 Appendix G limits). A thermal transient finite element analysis (FEA) is performed for the feedwater nozzle, and a polynomial curve-fit is applied to the through-wall stress distribution in the limiting nozzle corner location at each time point of the thermal transient. The subsequent method to evaluate Kit is given as:

Oa+2a 0537C1O

• 4a 3 3

=, . + Ir .537 C +-.2 0.448C,- + I3T 0.393C3(4)

Where: a = '/4 through-wall postulated flaw depth, a = '/4 t (in).

t =thickness of the cross-section through the limiting nozzle inner blend radius corner (in).

C 0t,,Ct = thermal stress third order polynomial coefficients, obtained from a C 2 t,C 3 t curve-fit of the extracted stresses from an FEM transient analysis.

The thermal stress polynomial coefficients are based on the polynomial form of c3-(x) =c + C . ( +aa/

+ - + C3 - . In this equation, "a" represents the radial distance in inches from the inside surface to any point on the crack front, and "amax" is the maximum crack depth, in inches.

Step 4: The allowable internal pressure of the RPV is calculated differently for each evaluation region. For the beltline region, the allowable pressure is determined as follows:

= -K (5) p allow M, -Ri Where: Pallow = the allowable RPV internal pressure (psig).

Kip = the allowable stress intensity factor due to membrane (pressure) stress, as defined in Equation 2 (ksli*n).

t = the RPV wall thickness, unique for each region (in).

Mm = the membrane correction factor for an inside surface axial flaw:

Mm = 1.85 for 4t < 2 Mm = 0.926 4t for 2 <4t < 3.464 Mm = 3.21 for 4t > 3.464 Ri = the inner radius of the RPV (in).

For the bottom head region, the allowable pressure is calculated with the following equation:

SCF . M0 , -Ri (6)

Where: SCF conservative stress concentration factor to account for bottom head penetration discontinuities; SCF = 3.0 per Reference [3].

Pallow, Kip, t, Mm and Ri are defined in the footnotes of Equation 5.

For the feedwater nozzle / upper vessel region, the allowable pressure is determined from a ratio of the allowable and applied stress intensity factors. The applied factor can be determined from an FEM that outputs the stresses due to the internal pressure on the nozzle /

RPV. The methodology for this approach is as follows:

K11 -Prei*

(7)

Where: Pref = RPV internal pressure at which the FEA stress coefficients (Equation 8) are valid (psig).

Kip-app = the applied pressure stress intensity factor (ksi*/in).

Pallow and Kip are defined in the footnotes of Equation 5.

File No.: 0800297.301 Page 6 of 47 Revision: I F0306-01 RO

Structuralintegrity Associates, Inc.

The applied pressure stress intensity factor is determined using a polynomial curve-fit approximation for the through-wall pressure stress distribution from an FEA, similar to the methodology of Equation 4:

K)TaLO=* .706Cp +/-* 2a a2j3 4a 3'

-aOp 1 2- 0-.537C

.448C2p + . 0.393C 3 , (8)

Where: a = 1/4 through-wall postulated flaw depth, a = 1/4 t (in).

t = thickness of the cross-section through the limiting nozzle inner blend radius corner (in).

Cop, Cp = pressure stress polynomial coefficients, obtained from a curve-fit C 2 p,C 3 p from the extracted stresses from an FEM unit pressure analysis.

Step 5: Steps I through 4 are repeated in order to generate a series of P-T points; the fluid temperature is incremented with each repetition. Calculations proceed in this iterative manner until the allowable reactor pressure (Pp-T) exceeds the maximum possible pressure. The maximum pressure limit is set to 1900 psig, since this value bounds the pre-service hydrostatic test pressure of 1,875 psig (see Section 3.0).

Step 6: The final P-T limits are calculated using the following equations:

TT = T + UT (9)

P-T = Pallo,,w - P H -UP (10)

Where: TP-T = the allowable coolant (metal) temperature (0 F).

UT = the coolant temperature instrument uncertainty ('F).

PP-T = the allowable reactor pressure (psig).

PH = the pressure head to account for the water in the RPV (psig).

Can be calculated from the following expression: PH = p Ah.

p = Water density at ambient temperature (lb/in 3 ).

Ah = elevation of full height water level in RPV (in.).

Up = the pressure instrument uncertainty (psig).

Step 7: The following additional minimum temperature requirements apply to the feedwater nozzle / upper vessel region, according to Table I of IOCFR50, Appendix G [2]:

" If the pressure is greater than 20% of the pre-service hydro-test pressure, the temperature must be greater than the RTNDT of the limiting flange material plus a temperature adjustment. For Curve A calculations, the temperature adjustment is 90'F; for Curve B, the temperature adjustment is 120'F.

• If the pressure is less than or equal to 20% of the pre-service hydro-test pressure, the minimum temperature must be greater than or equal to the RTNDT of the limiting flange material.

The P-T Curves for the hydrostatic leak test (Curve A) and normal operation - core not critical (Curve B) can be computed by following Steps I through 7. Values for Curve C, the core-critical operating curve, are generated from the requirements of IOCFR50 Appendix G [2] and the Curve A and Curve B limits. Table I of Reference [2] requires that core critical P-T limits be 40'F above any Curve A or Curve B limits at all pressures. IOCFR50 Appendix G [21 also stipulates that, above the 20% pressure transition point, the Curve C temperatures must be either the reference temperature (RTNDT) of the closure flange region plus 160'F, or the temperature required for the operating pressure (leak) test from Curve A, whichever is greater.

For P-T Curves A and B, the initial fluid temperature assumed in Step 1 is typically taken at the bolt-up temperature of the closure flange. According to Reference [2], the minimum bolt-up temperature is equal to the limiting material RTNDT of the regions affected by bolt-up stresses. Consistent with Reference [3], the minimum bolt-up temperature shall not be lower than 60'F. Thus, the minimum bolt-up temperature shall be 60'F or the material RTNDT, whichever is higher.

For P-T Curve C, when the reactor is critical, the initial fluid temperature is equal to the calculated minimum criticality temperature in this region. Table 1 of Reference [2] indicates that, for a BWR with normal operating water levels, the allowable temperature for initial criticality at the closure flange region is equal to the reference temperature (RTNDT) at the flange region plus 60'F.

3.0 DESIGN INPUTS / ASSUMPTIONS All design inputs and assumptions used to perform the NMP-1 P-T curve calculations are summarized in the input listings in Appendix A.

ART values in the NMP-1 beltline region are obtained from a previous Structural Integrity Associates (SI) calculation [4]. The calculations were performed in accordance with Nuclear Regulatory Commission (NRC) Regulatory Guide 1.99, Revision 2 (RG1.99) [5]. Based on Table 4 through Table 6 of Reference [4], the limiting beltline material is the P2112 lower shell plate. The limiting plate has ART values of 151.4'F, 159.0°F, and 167.4°F for 28, 36, and 46 EFPY, respectively.

NMP-1 has no large or small diameter nozzles (e.g. instrument nozzles) in the RPV beltline where the fluence exceeds 1.0x10 17 n/cm 2(E>IMeV).

Non-beltline regions are not subjected to significant fluence; therefore, initial reference temperature (RTNDT) values do not change, and are valid substitutions for corresponding ART values for these regions. Limiting RTNDT values for the upper vessel and flange region are taken from Reference [12c]

as 40°F. A complete list of RTNDT values is not available for the bottom head [13]. Of the available data, a value of 40'F is bounding [13]. Since this value is also bounding for the upper vessel and flange region, the limiting bottom head RTNDT is taken as 407F. This is consistent with References [12.d] and

[11, Section 10.3.1.1] which indicate the initial RTNDT for areas of reactor vessel material away from the high flux density region of the core is 40'F.

The inner radius of the RPV, per Reference [6, Table 4-5], is 106.5 inches. The vessel shell thickness is taken as 7.125 inches from the same source. Dimensions for the bottom head radius and thickness are obtained from Reference [10, Appendix A] as 106.719 inches and 8.75 inches, respectively.

The GE design hydro-test is defined as 1,250 psig [14] while the operating pressure test maximum is defined as 1,055 psig [16]. As described by IWB-5220 [15], the system leakage test (Curve A) pressure is taken as the operating pressure. The pre-service system hydrostatic test pressure was taken as 1.5 times the GE design pressure, resulting in a value of 1,875 psig, as confirmed in Reference [12a]. The instrument uncertainties for the Curve A hydrotest are 4°F and 10 psig [17]. For Curves B and C, the instrument uncertainties are 12.2°F and 52.2 psig [17].

The total internal height of the RPV is 766 inches, as shown in Table V-1 of Reference [12b]. The density of the water is assumed to be 62.4 lb/ft3 = 0.0361 lb/in 3. Thus, the static pressure adjustment due to the pressure head of the water in the RPV is conservatively calculated as 766-0.0361 = 27.66 psig for all evaluation regions, which addresses pressure test conditions when the RPV is fully flooded. The maximum cool-down rate of the vessel is 100°F/Hr per Reference [14]. Appendix B presents a bounding curve for a maximum heat-up / cool-down rate of 200°F/Hr.

According to Section 2.8 of Reference [3], the minimum bolt-up temperature for the RPV shall be no lower than 60'F. Since the RTNDT values for all regions highly stressed by bolt preload are all less than 60'F, the initial assumed fluid temperature in the iterative P-T curve calculation process is set equal to 60'F. A temperature increment of 2'F between subsequent iterations is assumed.

The 60'F initial temperature of Reference [3] replaces the previous lower limit of 60'F plus the limiting RTNDT for Curves A and 13, which was applied to the previous NMP-1 P-T curves [7a, 7b]. This additional conservatism was required in pre-1971 ASME Section III Code, but is no longer required in ASME Section XI, Appendix G [1] or IOCFR50, Appendix G [2]. When the Pressure-Temperature Limits Report (PTLR) [3] was developed, SI consciously recognized the additional 60'F margin and chose to exclude it, as it is not technically required.

Post processing was performed for a previously developed finite element analyses to extract the necessary polynomial coefficients describing the hoop stress distribution through the feedwater nozzle's limiting comer location (Equations 4 and 8). The thermal and pressure stresses were extracted using ANSYS [8].

Based upon a previous axisymmetric analysis, the limiting nozzle comer location was chosen based upon the highest total stress intensity due to pressure loading [9]. This path (Nodes 584 to 570) is utilized to extract thermal and pressure hoop stresses from the results databases [9]. For thermal stresses, the feedwater nozzle FEM was run with a thermal shock from 550'F to 100'F applied to the nozzle flow path with 100% flow [9]. This represents the thermal shock during the transient "Increase to Rated Power" [14]. It can be seen from Reference [14] that this is the highest thermal shock for the feedwater nozzle. The thermal stresses are taken as function of time during the transient. Each stress distribution is fit with a third-order polynomial as a function of distance into the nozzle. The thermal stress intensity factor (Equation 4) is calculated for all time steps. The most limiting (highest) value is chosen, corresponding to a time of 5,000 seconds. Since operation is along the saturation curve, the File No.: 0800297.301 Page 9 of 47 Revision: 1 F0306-OIRO

i Structural Integrity Associates, Inc.

thermal stress intensity factor is scaled to reflect the worst-case step change due to available temperature difference. The pressure stresses are taken at steady state. The pressure stress analysis was performed for a 1,000 psig RPV pressure and the results scaled to reflect the operating pressure of 1,055 psig. The supporting *.out files of Reference [9] show that the path selected defines the nozzle comer thickness to be 7.8427 inches. Thus, the postulated flaw location at 1/4t is 1.9607 inches. Appendix C lists the ANSYS files included in the electronic supporting files. Note that only the finite element model developed in Reference [9] is used in this calculation; the Green's Function was not utilized.

The analyzed transient "Increase to Rated Power" is associated with the startup/shutdown event for the feedwater nozzle [14]. The evaluated shock is from 550'F to 1007F, which represents the design basis definition for this event. Figure 3-3 of Reference [18] shows a plant specific Turbine Roll transient for Unit I to be a shock from 485°F to 161'F. Even considering a potential 357F feedwater temperature, page 4 of Appendix G states that the 1617F temperature would drop to 123°F [18]. Both of these are bounded by the analyzed 5507F to 100°F shock.

4.0 CALCULATIONS The P-T curves in this calculation were developed using an Excel spreadsheet, which is independently verified for use on a project-specific basis in accordance with SI's QA Program.

The polynomial stress coefficients in Table I were applied to Equations 4 and 8. The resulting pressure stress intensity (Kip-applied) and thermal stress intensity (Kt) factors are 86.72 ksi'lin and 45.60 ksi/in, respectively.

4.1 Pressure Test (Curve A)

The minimum bolt-up temperature of 60'F is applied to all regions as the initial temperature in the iterative calculation process. The static fracture toughness (K,,) is calculated for all regions using Equation 1. The resulting value of K1t, along with a safety factor of 1.5, is used in Equation 2 to calculate the pressure stress intensity (Kip)- The allowable RPV pressure is calculated for the beltline, bottom head, and upper vessel regions using Equations 5, 6, and 7, respectively. For the feedwater nozzle / upper vessel region, the additional constraints specified in Step 7 of Section 2.0 are applied.

Final P-T limits for temperature and pressure are obtained from Equations 9 and 10, respectively.

The data resulting from each P-T curve calculation was tabulated. Values for the beltline region at 28, 36, and 46 EFPY are given in Table 2, Table 3, and Table 4, respectively. Data for the bottom head region is listed in Table 5, and data for the feedwater nozzle / upper vessel region is presented in Table

6. The data for each region was graphed, and the resulting P-T curves for 28, 36, and 46 EFPY are ided in Figure 1, Figure 2, and Figure 3, respectively.

4.2 Normal Operation - Core Not Critical (Curve B)

The minimum bolt-up temperature of 60'F is applied to all regions as the initial temperature in the iterative calculation process. The static fracture toughness (K1 t) is calculated for all regions using Equation 1. The thermal stress intensity factor (K,,) is calculated for the beltline and bottom head regions using Equation 3, and for the feedwater nozzle using Equation 4.

The resulting values of Kic and Kit, along with a safety factor of 2.0, are used in Equation 2 to calculate the pressure stress intensity (Kip). The allowable RPV pressure was calculated for the beltline, bottom head, and upper vessel regions using Equations 5, 6, and 7, respectively. For the feedwater nozzle /

upper vessel region, the additional constraints specified in Step 7 of Section 2.0 are applied. Final P-T limits for temperature and pressure are obtained from Equations 9 and 10, respectively.

The data resulting from each P-T curve calculation was tabulated. Values for the beltline region at 28, 36, and 46 EFPY are given in Table 7, Table 8, and Table 9, respectively. Data for the bottom head region is listed in Table 10, and data for the feedwater nozzle / upper vessel region is presented in Table

11. The data for each region was graphed, and the resulting P-T curves for 28, 36, and 46 EFPY are provided in Figure 4, Figure 5, and Figure 6, respectively.

4.3 Normal Operation - Core Critical (Curve C)

The pressure and temperature values for Curve C are calculated in a similar manner as Curve B, with several exceptions. The initial evaluation temperature is calculated as the limiting closure flange region RTNDT that is highly stressed by the bolt preload (in this case, that of the closure flange region: 40'F per Section 3.0) plus 60'F, resulting in a minimum critical temperature of 100'F. When the pressure exceeds 20% of the pre-service system hydro-test pressure (20% of 1,875 psig = 375 psig), the P-T limits are specified as 40'F higher than the Curve B values. The minimum temperature above the 20%

pressure transition point is always greater than the reference temperature (RTNDT) of the closure region plus 160'F, or the temperature required for the hydrostatic pressure test. The final Curve C values are taken as the absolute maximum between the three regions of Curve B P-T curves.

Tabulated overall values for Curve C are provided at 28, 36, and 46 EFPY in Table 12, Table 13, and Table 14, respectively. The corresponding P-T curves for 28, 36, and 46 EFPY are provided in Figure 7, Figure 8, and Figure 9, respectively.

BLO INTRODUCTION This appendix modifies the Nine Mile Point, Unit 1 P-T curves for a heat-up/cool-down rate of up to 200°F/Hr. A single curve is presented that bounds the beltline, bottom head, and non-beltline (feedwater nozzle / upper vessel) regions and is valid for up to 46 EFPY. The curve bounds the following plant conditions: Operating Pressure (Leak) Test (Curve A), Normal Operation - Core Not Critical (Curve B),

and Normal Operation - Core Critical (Curve C). The curve is developed using the methodology of the 2001 Edition, 2003 Addenda of the ASME Code,Section XI, Appendix G [1], and IOCFR50 Appendix G [2]. This appendix has been developed in accordance with the methodology of the BWROG Licensing Topical Report, "Pressure-Temperature Limits Report Methodology for Boiling Water Reactors" [3]. This appendix is provided for engineering purposes only and is not intended to be included in the PTLR.

B2.0 MIETHODOLOGY The methodology for calculating the P-T curve described in Section 2.0 remains unchanged. Only the calculation of the thermal stress intensity factor, Kit, is affected by the increased heat-up / cool-down rate. Kit is computed in different ways based on the evaluation region. As described in Section 2.0, the feedwater nozzle / upper vessel region Kit is obtained from the stress distribution output of a finite element model. The transient "Turbine Roll and Increase to Rated Power" consists of a 450'F step change [14], which bounds the increased heat-up / cool-down rate. Thus, the Kit calculation for the feedwater nozzle / upper vessel region is unaffected. For the beltline and bottom head regions, Kit is determined based on the ASME Section XI, Nonmandatory Appendix G method, using the following equation from Section 2.0:

0.953 x 1063 -CR. t 2 5 Ki, = (3)

Where: CR = the cooldown rate of the vessel (°F/hr).

t = the RPV wall thickness, unique for each region (in).

B3.0 CALCULATIONS The P-T curve is developed using an Excel spreadsheet, which is independently verified for use on a project-specific basis in accordance with SI's QA Program.

Figure BI presets the bounding curve for a 200°F/Hr heat-up / cool-down rate. This information is also presented in tabular form in Table B1. The P-T curve bounds the beltline, bottom head, and non-beltline (feedwater nozzle / upper vessel) regions and is valid for up to 46 EFPY. The curve bounds the following plant conditions: Operating Pressure (Leak) Test (Curve A), Normal Operation - Core Not Critical (Curve B), and Normal Operation - Core Critical (Curve C).
