1.0 INTRODUCTION

This calculation develops pressure-temperature (P-T) limit curves for the beltline, bottom head, and non-beitline regions of the Hatch Nuclear Plant, Unit 1 (HNP-1) reactor pressure vessel (RPV). The P-T curves are developed for 38 and 49.3 effective full power years (EFPY) of operation, and for 100OF/hr and 200°F/hr thermal transients.

The P-T curves are prepared using the methods documented in the Boiling Water Reactor Owner's Group (BWROG) Licensing Topical Reports (LTRs), "Pressure Temperature Limits Report Methodology for Boiling Water Reactors" [ 1] and "Linear Elastic Fracture Mechanics Evaluation of General Electric Boiling Water Reactor Water Level Instrument Nozzles for Pressure-Temperature Curve Evaluations" [2]. These LTRs satisfy the requirements of 1OCFR50 Appendix G [3] and the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code,Section XI, Non-mandatory Appendix G [4].2.0 METHODOLOGY A full set of P-T curves, applicable to the following plant conditions, are prepared: 1. Pressure Test (Curve A), 2. Normal Operation

-Core Not Critical (Curve B), and 3. Normal Operation

-Core Critical (Curve C).For each plant condition above, separate curves are provided for each of the following three regions of the RPV as well as a composite curve for the entire RPV: 1. The beltline region, 2. The bottom head region, 3. The non-beltline region, 4. Composite curve (bounding curve for all regions)In some cases, a region may contain more than one component which is considered for development of the associated P-T curve. For HINP-1, the curve for each vessel region identified above is composed from the bounding P-T limits determined for the following components:

1. Beltline: a. Beltline shell b. Water level instrument (WLI) nozzle, N16 2. Non-beltline

a. Feedwater (FW) nozzle b. 10CFR50 Appendix G limits [3]3. Bottom Head: a. Bottom head penetrations (in-core monitor housings, control rod drive housings)b. Core DP nozzle Consequently, separate curves are prepared for each component considered for each region then a bounding curve is drawn from the individual curves.File No.: 1001527.304 Page 6 of 46 Revision:

2 F0306-01R1 Structural Integrity Associates, /nc?Complete sets of P-T curves, as identified above, are provided for a 100 °F/hr and 200 °F/hr thermal transient at 38 and 49.3 EFPY of operation.

The methodology for calculating P-T curves, described below, is taken from Reference

[1] unless specified otherwise.

Additional guidance regarding analysis of WLI nozzles is taken from Reference[2].The P-T curves are calculated by means of an iterative procedure, in which the following steps are performed:

Step 1: A fluid temperature, T, is assumed. The P-T curves are calculated considering a postulated flaw with a 6:1 aspect ratio that extends '1/4 of the way through the vessel wall. The temperature at the postulated flaw tip is assumed equal to the coolant temperature.

Step 2: The static fracture toughness, K 1 0 , is computed using the following equation: K 1 c 33.2 + 20.734 .e°°2(r-AT)

(1)Where: K 1 0 = the lower bound static fracture toughness (ksi'lin).

T = the metal temperature at the tip of the postulated 1/4 through-wall flaw (0 F).ART = the Adjusted Reference Temperature (ART) for the limiting material in the RPV region under consideration

(°F).Step 3: The allowable stress intensity factor due to pressure, Kip, is calculated as: Kzp -(2)Where: K 1 ip the allowable stress intensity factor due to membrane (pressure) stress (ksi'Iin).

Ki 0 the lower bound static fracture toughness calculated in Eq. (1)(ksi\Iin).

Kit the thermal stress intensity factor (ksi Win) from through wall thermal gradients.

SF =the ASME Code recommended safety factor, based on the reactor condition.

For hydrostatic and leak test conditions (i.e., P-T Curve A), SF = 1.5. For normal operation, both core non-critical and core critical (i.e., P-T Curves B and C), 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).File No.: 1001527.304 Page 7 of 46 Revision:

2 FO306-01R1 VStructural Integrity Associates, IncY For Curve B and Curve C calculations, K 1 t is computed in different ways based on the evaluated region. For the beitline, with the exception of nozzles, and bottom head regions, Kit is determined using the following equation: K 1 , =O0.953 x10-3**CR. t 2 5 (3)Where: CR = the cooldown rate of the vessel (°F/hr).t= the RPV wall thickness (in).For the FW nozzle, K 1 t is obtained from the stress distribution output of a plant specific finite element analyses (FEA). A polynomial curve-fit is determined for the through-wall stress distribution at the bounding time point. The linear elastic fracture mechanics (LEFM) solution for K 1 t is: K 1 ,no0.06C,0.57 2 c 1 0.48 +2 0.33 ~3 1(4 Where: a =/1/4 through-wall postulated flaw depth, a = 1/4 t (in).t = thickness of the cross-section through the nozzle at the limiting path near the inner blend radius (in).Cot,Clt, = thermal stress polynomial coefficients, obtained from a curve-Czt,C 3 t fit of the extracted stresses from a transient FEA.The thermal stress polynomial coefficients are based on the assumed polynomial form ofo'(x) =Co +C 1.x +C 2* x 2 + C 3*. x 3.In this equation, "x" represents the radial distance in inches from the inside surface to any point on the crack face.For the WLI nozzle, the nozzle assembly consists of an insert attached to the RPV with a partial penetration weld. The nozzle material is not ferritic and does not need to be specifically evaluated.

However, the effect of the penetration on the adjacent shell must be considered.

Ki1-ramp = 874,

+t.)-]-20.715 (5)Where: Ki-ramp = the K 1 t (thermal stress intensity factor from through wall thermal gradients) for a WLI nozzle subjected to 1 00°F/hr thermal transient (ksi\/in).

ct = the instrument nozzle material coefficient of thermal expansion at the highest thermal ramp temperature (in/in/°F).

tv = the vessel thickness (in).tn = the nozzle thickness (in).File No.: 1001527.304 Page 8 of 46 Revision:

2 F0306-01RI VStructural Integrity Associates, IncY Larger heat-up/cool-down rates are conservatively considered by scaling the stress intensity factor obtained using Eq. (5) by the ratio of the desired heat-up/cool-down rate to 100 °F/hr.Since the P-T curves are applicable to all Level A/B events, the bounding Level A/B events, for each region and component, identified from the vessel and nozzle thermal cycle diagrams[7], are considered when calculating the Kit above.Step 4: The allowable internal pressure of the RPV is calculated differently for each evaluation region.For the beltline region, with the exception of nozzles, the allowable pressure is determined as follows: Pallow -M m .R (6)Where: Pailow = the allowable RPV internal pressure (psig).Kip = the allowable stress intensity factor due to membrane (pressure) stress, as defined in Eq. (2) t = the RPV wall thickness (in).Mm = the membrane correction factor for an inside surface axial flaw: Mm =1.85 for /t< 2 Mm = 0.926 "It for 2 <.It < 3.464 Mm =3.21 for "It >3.464.Ri = the inner radius of the RPV, per region (in).For the bottom head region, the allowable pressure is calculated with the following equation: 2.K .t Polw= (7)SCF. Mm

R, Where: SCF = conservative stress concentration factor to account for bottom head penetration discontinuities; SCF = 3.0 per Reference

[1].Paiiow, K 1 p, t, Mm and Ri are defined in Eq. (6).The bottom head region methodology for calculating the allowable pressure shown in Eq. (7)above is applied for the thicker shell portion of the HNP-1 bottom head. It is noted that the Core DP nozzle at HNP-1 penetrates a section of the bottom head in which the shell is 3 3/16" thick. Use of Eq. (7) to treat the effect of the penetration would be excessively conservative.

Preliminary calculations showed that this approach produced a bottom head curve which bounded the entire vessel. Consequently, the effect of the Core DP nozzle penetration is considered in a manner similar to the FW nozzle, as described below.File No.: 1001527.304 Page 9 of 46 Revision:

2 F0306-01R1 Structural Integrity Associates, Inc.P For the FW nozzle the allowable pressure is determined from a ratio of the allowable and applied stress intensity factors. The applied factor can be determined from a FEA that determines the stresses due to the internal pressure on the nozzle and RPV. The methodology for this approach is as follows: p K 1 p "ref altlow, -(8)Where: Pref = RPV internal pressure at which the FEA stress coefficients (Eq.(9)) are determined (psi).KIp-app --the applied pressure stress intensity factor Pallow and K 1 p are defined as in Eq. (6)..The applied pressure stress intensity factor is determined using a polynomial curve-fit approximation for the through-wall pressure stress distribution from a FEA and the LEFM solution given in Eq. (4): KIp.app= -p 0.448/-i-12p

However, the effect of the penetration on the adjacent shell must be considered.

The allowable pressure is determined from the ratio of the allowable and applied stress intensity factors given in Equation 8. The applied stress intensity factor, for a 1000 psig load case, is calculated generically as follows [2, Equation 8-1]: KI Pressure =2.9045IR tF.+ +/-t,, 1-4.434 (10)-L. ]" Where: KI-pressure

=generic Kip-app for the WLI nozzle (ksi'lin).

R = RPV nominal inside radius (in).tv and tn are described as in Eq. (5).The allowable pressure for the WLI nozzle is then calculated using Eq. (8), similar to the FW nozzle.File No.: 1001527.304 Page 10 of 46 Revision:

2 F0306-01IRI Structural Integrity Associates, Inc.*Step 5: Steps 1 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 1,300.psig. This value bounds expected pressures.

Step 6: Table 1 below summarizes the minimum temperature requirements contained in 10OCFR50, Appendix G [3, Table 1], which are applicable to the material highly stressed by the main closure flange bolt preload (non-beltline curve).

[1]. Further, some utilities specifically request that the minimum moderator temperature used in the plant shutdown margin evaluation be applied as a minimum bolt-up temperature requirement; therefore, it is also included in Table 1 above. However, to address the NRC condition regarding lowest service temperature in Reference

[1 ], the minimum temperature is set to 76 0 F, which is equal to the RTNDT, max + 60 0 F. This value is consistent with the File No.: 1001527.304 Revision:

2 Page 11 of 46 F0306-01IR1 V Structural Integrity Associates, Inc.'previous minimum temperature limits developed in [11], and is higher than the minimum bolt-up temperature specified in [ 12].Step 7: Uncertainty in the RPV pressure and metal temperature measurements is incorporated by adjusting the P-T curve pressure and temperature using the following equations:

TpTr = T +UT (11)PP-r = -PH- UP (12)Where: Tp-T = The allowable coolant (metal) temperature (0 F).UT = The coolant temperature instrument uncertainty (0 F).PP-j = The allowable reactor pressure (psig).P 1 1 = The pressure head to account for the water in the RPV (psig).Can be calculated from the following expression:

PIH= 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).Steps 1 through 7, above, are implemented for all components, in all regions, for each heat-up/cool-down rate, and at all EFPY.3.0 " ASSUMPTIONS The 10OCFR5 0 Appendix G [3] and AsME Code [4] requirements and methods are considered to be supported in their respective technical basis documentation; therefore, the assumptions inherent in the ASME B&PV Code methods utilized for this evaluation are not specifically identified and justified in this calculation.

Only those assumptions specific to this calculation are identified and justified here.The following assumptions are used in preparation of the HNP- 1 P-T curves:.1. The bounding ART for the beltline materials is used in the calculation of the WLI nozzle curve.This assumption is conservative since the WLI nozzle is located near the upper limit of the beltline region and the cumulative fluence at this location is substantially lower than for the beitline location corresponding to the peak fluence. Use of a fluence representative of the location in the beltline shell corresponding to the WLJ nozzle location would result in an ART, local to the WLI nozzle, which is lower than used in the present evaluation.

Since the fluence at the WLI nozzle location is not specifically provided in the available fluence analysis results, the peak beltline value is used in this calculation.

Conservatism can be removed from the P-T curves by considering a WLI nozzle fluence in the ART calculation

[5], which would result in a lower ART used in the WLI nozzle beltline curve.2. The full-vessel height is used in the calculation of the static head contributed by the coolant in the RPV.This assumption is conservative in that the static head at the non-beltline regions is slightly lower than that of the bottom head curve; however, the difference in static head is small; therefore, the File No.: 1001527.304 Page 12 of 46 Revision:

2 F0306-01RI Structural Integrity Associates, IncY added complexity in considering different static head values for each region of the vessel is not considered beneficial.

3. The FW nozzle is the bounding non-beltline component of the RPV.This assumption is made because: a. The geometric discontinuity caused by the nozzle penetration in the RPV shell causes a stress concentration which results in larger pressure induced stresses than would be calculated in the shell regions of the RPV.b. The FW nozzle experiences more severe thermal transients than most of the other nozzles because of the feedwater injection temperature which causes larger thermal stresses than are experienced in the shell region of the RPV.c. Although some other nozzles can experience thermal transients, which Would cause thermal stresses larger than those calculated for the shell regions of the RPV, and some nozzles are larger diameter than the FW nozzle, which could result in a slightly larger K 1 p, the combined stresses from the applied thermal and pressure loads are considered to bound all other non-beltiline discontinuities.

4. Application of a SCF = 3.0 to the membrane pressure stress in the bottom head bounds the effect of the bottom head penetrations on the stress field in this region of the vessel.Bottom head penetrations will create geometric discontinuities into the bottom head hemisphere resulting in high localized stresses.

This effect must be considered in calculating the stress intensity factor from internal pressure.

Rather than performing a plant specific analysis, SI applies a conservative SCF for a circular hole in a flat plate subjected to a uniaxial load to the membrane stress in the shell caused by the internal pressure.

The assumption of SCF -- 3.0 is conservative because: a. It applies a peak SCF to the membrane stress which essentially, intensifies the stress through the entire shell thickness and along the entire crack face of the postulated flaw rather than intensifying the stress local to the penetration and considering the stress attenuation away from the penetration, b. Review of SCFs for circular holes in plates subjected to an equi-bi-axial stress state as well as SCFs for arrays of circular holes in shells, shows that the SCF is likely closer to 2-2.5 rather than 3.0.Consequently, the method utilized by SI is expedient, as intended, and conservatively bounds the expected effect of bottom head penetrations because a bounding SCF is used and applied as a membrane stress correction factor.5. ASME XI, Non-mandatory Appendix G, Paragraph G-22 14.3 [4] is used to calculate the thermal stress intensity factor for heat-up / cool-down rates greater than 100 °F/hr.The ASME Code [4] acknowledges that this methodology is conservative when applied to heat-up / cool-down rates greater than 100 0 F/hr; therefore, the results obtained using this method for the 200 0 F/hr heat-up / cool-down rate are conservative.

Conservatism can be removed, if File No.: 1001527.304 Page 13 of 46 Revision:

2 F0306-01RI Structural Integrit, Associates, Inc?necessary, by solving the thermo-elastic problem for the stresses in the vessel shell then calculating the stress intensity factor using the plant specific stress distribution.

0*F 5.0 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 Nuclear QA program. Four cases are evaluated, corresponding to two EFPY values (38 and 49.3) and two cool-down rates (100 and 200°F/hr). P-T limits are calculated from 0 to 1300 psig. Supporting calculations for all curves are included in Appendix B.Because BWR operation is typically along the saturation curve, the limiting K 1 t for the FW nozzle is scaled to reflect the worst-case step change due to the available temperature difference between the saturation temperature at a given pressure and the 100 0 F feedwater temperature.

It is recognized that at low temperatures, the available temperature difference is insignificant, which could result in a near zero Kit. Therefore, a minimum K 1 u is calculated for both the 100 0 F/hr and 200 0 F/hr cool-down rates; scaling of the non-beltline

/ feedwater nozzle Kit based on the available temperature difference is not allowed below the minimum Kit corresponding to the cool-down rate, being evaluated.

The composite P-T curves are extended below 0 psig to -14.7 psig based on the evaluation documented in Reference

[13], which demonstrates that the P-T curves are applicable to negative gauge pressures.

Since the P-T curve calculation methods used do not specifically apply to negative values of pressure, the tabulated results start at 0 psig. However, the minimum RPV pressure is -14.7 psig.5.1 Pressure Test (Curve A)The minimum bolt-up temperature of 76 0 F minus instrument uncertainty (0°F) is applied to all regions as the initial temperature in the iterative calculation process. The static fracture toughness (Kit) is calculated for all regions using Eq. (1). The resulting value of K 1 t, along with a safety factor ofl .5 is used in Eq. (2) to calculate the pressure stress intensity factor (K 1 p). The allowable RPV pressure is calculated for the beltline, bottom head and Non-Beltline regions 'using Eq. (6, 7, and 8), as appropriate.

For the non-beltline region (feedwater nozzle / upper vessel), the additional constraints specified in Step 6 of Section 2.0 are applied. Final P-T limits for temperature and pressure are obtained from Eq. (12 and 13), respectively.

2 F0306-01RI VStructural Integrity Associates, Inc.Y Since the thermal stress intensity factor is taken as zero for Curve A, the cool-down rates do not affect the results for Curve A.Values for the composite beltline region curves for 38 and 49.3 EFPY are listed in Table 2 and Table 3, respectively.

Additionally, more detailed data for the composite beltline are provided in Appendix B.Data for the composite bottom head region curve for all EFPY is listed in Table 4.

Additional data and curves for each region are included in Appendix B.5.2 Normal Operation

-Core Not Critical (Curve B)The minimum bolt-up temperature of 76°F minus coolant temperature instrument uncertainty (0 0 F) is applied to all regions as the initial temperature in the iterative calculation process. The static fracture toughness (Kic) is calculated for all regions using Eq. (1). The thermal stress intensity factor (K 1 t) is calculated for the beltline plate and bottom head regions using Eq. (3), for the FW nozzle using Eq. (4), and for the WLI (N16) nozzle using Eq. (5).The resulting values of Kit and Kit, along with a safety factor of 2.0, are used in Eq. (2) to calculate the pressure stress intensity factor (K 1 p). The allowable RPV pressure is calculated for the beltline, bottom head, and non-beltline regions using Eq. (6, 7, and 8), as appropriate.

For the non-beltline (FW nozzle /upper vessel) region, the additional constraints specified in Step 6 of Section 2.0 are applied. Final P-T limits for temperature and pressure are obtained from Eq. (12 and 13), respectively.

The data resulting from each P-T curve calculation is tabulated.

Values for the composite beltline region with a 100°F/hr cool-down rate at 38 and 49.3 EFPY are listed in Table 6 and Table 7, respectively.

Values for the composite beltline region with a 200°F/hr cool-down rate at 38 and 49.3 EFPY are listed in Table 8 and Table 9, respectively.

-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 non-beltline RTNDT that is highly stressed by the bolt preload (in this case, that of the closure flange region: 16 0 F per Section 3.0) plus 60°F, resulting in a minimum critical temperature of 76 °F. When the pressure exceeds 20% of the system hydrostatic test pressure (20% of 1,563 psig =313 psig), the P-T limits are specified as 40°F higher than the Curve B values. The minimum temperature above the 20%of the pre-service system hydrostatic test pressure is always greater than the reference temperature (RTNDT) of the closure region plus 160°F, or is taken as the minimum temperature required for the hydrostatic pressure test. The final Curve C values are taken as the absolute maximum between the regions of the beitline, the bottom head, and the non-beitline.

The data resulting from each P-T curve calculation is tabulated.

Values for the composite beltllne region with a 100°F/hr cool-down rate at 38 and 49.3 EFPY are listed in Table 14 and Table 15, respectively.

Values for the composite beltline region with a 200°F/hr cool-down rate at 38 and 49.3 EFPY are listed in Table 16 and Table 17, respectively.

Data for the bottom head region with 100°F/hr and 200°F/hr cool-down rates are listed in Table 18 and Table 19, respectively.

Data for the non-beltline (FW nozzle / upper vessel) region with 100°F/hr and 200°F/hr cool-down rates are listed in Table 20 and Table 21, respectively.

The data for each region is graphed, and the resulting composite Curve C for 38 and 49.3 EFPY with a 100°F/hr cool-down rate are provided in Figure 7 and Figure 8, respectively.

The resulting composite Curve C for 38 and 49.3 EFPY with a 200°F/hr cool-down rate are provided in Figure 9 and Figure 10, respectively.

Additional data and curves for each region are included in Appendix B.Note that the Beltline Region curves for the 200 0 F/hr thermal transient at 38 and 49.3 EFPY shown in Tables 16 and 17 and Figures 9 and 10 exhibit negative pressures at the lower end of the curve. This is non-realistic and essentially indicates a higher minimum temperature for this region than for the other regions of the RPV. Since these curves are not intended for normal operation and are intended only to disposition out-of-specification thermal transients these results do not pose any operational difficulties.
