Specifically, the LCO states that the RCS pressure, RCS temperature, and RCS heatup and cooldown rates shall be maintained within the limits specified in Figures 3.4.3-1 and 3.4.3-2. Figures 3.4.3-1 and 3.4.3-2 contain PIT limit curves for heatup, cooldown, inservice leak and hydrostatic (ISLH) testing, and data for the maximum rate of change of reactor coolant temperature.
Each PIT limit curve defines an acceptable region for operation.
The curves are used during heatup and cooldown maneuvering, by monitoring and comparing pressure and temperature indications to the applicable curve to ensure that operation is within the allowable region. The proposed change replaces TS Section 3.4.3, Figures 3.4.3-1 and 3.4.3-2, with updated curves (see the attached markup of TS pages and retyped TS pages) that are applicable up to 50 effective full power years (EFPY). This is necessary since the current Figures 3.4.3-1 and 3.4.3-2 are applicable to 35 EFPY, which is projected to be reached at the start of cycle 31. 1.2 Basis For Proposed Change The technical basis for the proposed revision to the heatup and cooldown limits is provided in the attached Westinghouse report, WCAP-15827, "H. B. Robinson Unit 2 Heatup and Cooldown Limit Curves for Normal Operation." The fluence values used in these analyses were updated and documented in WCAP-15805, "Analysis of Capsule X from the Carolina Power and Light Company H. B. Robinson Unit 2 Reactor Vessel Radiation Surveillance Program," which was previously submitted to the NRC by letter, dated April 25, 2002. As explained in the attached WCAP-15827 report, the heatup and cooldown curves were generated using the most limiting material adjusted reference temperature (ART) values and the NRG-approved methodology documented in WCAP-14040-NP-A, Revision 2, "Methodology Used to Develop Cold Overpressure Mitigating System Setpoints and RCS Heatup and Cooldown Limit Curves," with the exception of the following:
The fluence values are calculated fluence values (i.e., comply with Regulatory Guide 1.190), and are not the best-estimate fluence values. K 1 c (which is the material toughness property measured in terms of stress intensity factor, Ki. which will lead to non-ductile crack propagation) is used in place of K 1 a (which is the critical value of the stress intensity factor, K1, for crack arrest as a function of temperature).
This methodology is consistent with the approved ASME Code Case N-641.
U. S. Nuclear Regulatory Commission Attachment 1 to Serial: RNP-RA/15-0083 Page 3 of 5 The 1996 Version of Appendix G to ASME Section XI was used in lieu of the 1989 version. Additionally, the proposed heatup and cooldown limits were further adjusted by +20°F and -80 psig to account for instrument error, which is consistent with the current licensing basis. The normal shift of the Prr limit curves as irradiation time increases is toward lower pressures for a given temperature.
The pressure-temperature curves for 50 EFPY were developed using the "axial-flaw" methodology with the most limiting " axial-flaw" ARTs and the "circ-flaw" methodology (Code Case N-641) with the most limiting "circ-flaw" ARTs. This allows higher pressures at a given temperature, and the limit curves shift to lower temperatures and higher pressures upon first use of the methodology.
This method has been accepted by the NRC in the past as an exemption to ASME Section XI, and in April 2004, the NRC published Regulatory Issue Summary 2004-04, "Use of Code Cases N-588, N-640, and N-641 in Developing Pressure-Temperature Operating Limits," which allows the use of the Code Case methodology with no need for an exemption application. Review of the low temperature overpressure protection limits confirmed that no changes are required as a result of the revised reactor pressure vessel analyses and limits. Since the proposed RCS Prr limits are based on applicable NRG-approved methodology, the proposed amendment will continue to maintain appropriate limits for the HBRSEP2 RCS up to 50 EFPY. 2.0 REGULATORY ANALYSIS 2.1 No Significant Hazards Consideration Determination As required by 10 CFR 50.91 (a)(1 ), this analysis is provided to demonstrate that the proposed license amendment does not involve a significant hazard. Conformance of the proposed amendment to the standards for a determination of no significant hazards, as defined in 10 CFR 50.92, is shown in the following: 1) Does the proposed license amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
No. The proposed RCS Prr limits are based on NRG-approved methodology and will cont i nue to maintain appropriate limits for the HBRSEP2 RCS up to 50 EFPY. These changes provide appropriate limits for pressure and temperature during heatup and cooldown of the RCS, thus ensuring that the probability of RCS failure is maintained acceptably low. These limits are not directly related to the consequences of accidents.
Therefore , the proposed amendment does not result in an increase in the probability or consequences of an accident previously evaluated.
U. S. Nuclear Regulatory Commission Attachment 1 to Serial: RNP-RA/15-0083 Page 4 of 5 2) Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
No. The proposed changes will continue to ensure that the RCS will be maintained within appropriate pressure and temperature limits during heatup and cooldown.
No physical changes to the HBRSEP2 systems, structures, or components are being implemented. There are no new or different accident initiators or sequences being created by the proposed Technical Specifications changes. Therefore, these changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3) Does the proposed change involve a significant reduction in margin of safety? No. The proposed changes ensure that the margin of safety for the fission product barriers protected by these functions will continue to be maintained.
This conclusion is based on use of the applicable NRC-approved methodology for developing and establishing the proposed RCS PIT limits. Therefore, these changes do not involve a significant reduction in the margin of safety. Based on the preceding analysis, it is concluded that the replacement of TS Section 3.4.3, Figures 3.4.3-1 and 3.4.3-2, with updated curves that are applicable up to 50 EFPY does not involve a significant hazards consideration finding as defined in 10 CFR 50.92. 3.0 ENVIRONMENTAL ANALYSIS 10 CFR 51.22(c)(9) provides criteria for identification of licensing and regulatory actions for categorical exclusion from performing an environmental assessment.
A proposed change for an operating license for a facility requires no environmental assessment if operation of the facility in accordance with the proposed change would not (i) involve a significant hazards consideration; (ii) result in a significant change in the types or significant increases in the amounts of any effluents that may be released offsite; (iii) result in a significant increase in individual or cumulative occupational radiation exposure.
Duke Energy Progress, Inc., has reviewed this request and determined that the proposed change meets 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 needs to be prepared in connection with the issuance of the amendment.
The basis for this determination is as follows: Proposed Change The proposed change will revise the RCS pressure and temperature limits by replacing Technical Specifications Section 3.4.3, "RCS Pressure and Temperature (PIT) Limits," Figures 3.4.3-1 and 3.4.3-2, with figures that are applicable up to 50 EFPY.
U. S. Nuclear Regulatory Commission Attachment 1 to Serial: RNP-RA/15-0083 Page 5 of 5 The proposed changes meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) for the following reasons: 1) As demonstrated in the No Significant Hazards Consideration Determination, the proposed changes do not involve a significant hazards consideration.
- 2) The proposed changes revise the RCS pressure and temperature limits by replacing Technical Specifications Section 3.4.3, "RCS Pressure and Temperature (PIT) Limits," Figures 3.4.3-1 and 3.4.3-2, with figures that are applicable up to 50 EFPY. These changes do not affect the generation or control of effluents.
Therefore, the proposed changes will not result in a significant change in the types or significant increases in the amounts of any effluents that may be released offsite. 3) The proposed changes, as previously described, do not affect any parameters that would cause an increase in occupational radiation exposure. There are no proposed physical changes to the facility or any process changes that would result in additional radiation exposure.
Therefore, the proposed changes will not result in a significant increase in individual or cumulative occupational radiation exposure.

SUMMARY
This report provides the methodology and results of the generation ofheatup and cooldown pressure temperature limit curves for nonn:il operation of the H.B. Robinson Unit 2 reactor vessel. In addition, the vessel wall temperature dati is documented herein under the Appendices.
The PT curves were generated based on the latest available reactor vessel infommtion and Ouenees {WCAP-1580S)fll, which were up<bted to reflect actual power realized from the R021 uprate. The new H.B. Robinson Unit 2 heatup and cooldo\\11 pressure-temperature limit curves were generated using ASME Code Case N-6411 21 (which allows the use of the Kie methodology and "Circ. Flaw" methodology) and the a.'tial flaw methodology of the 1995 ASME Code,Section XI through the 1996 Addcndat 3 l. It should be noted that H.B. Robinson was limited at the l/4T and 3/4T locations by the upper to intermediate shell circumferential weld with exception to the 3/4T location at 30 EFPY (Limited here by the upper shell plate Wl0201*1).
The limiting axial material was the upper shell plate Wl0201*1.
The pressure-temperature (PT) limit curves presented in Section S and Appendix A arc developed using the "axial-flaw
methodology with the most limiting "a"<i:il-flaw" adjusted reference temperatures (ARTs), and the "Circ Flaw" Methodology (ASME Code Case N-641. formerly known as N-Sssl*I) with the mQfil limiting "Circ. Flaw" ART values. The "a.'tial-flaw" ART values produce a more limiting PT curve overall with exception to the higher temperatures where at a ccrt3in point, depending on the EFPY, the curve could switch from "axial-flaw" limited to a "circ-flaw" limited curve. When and where this occurs is noted within the data tables for each specific PT-limit curve. [Note that the PT limit curves of Appendix A arc the same as those in Section S, with exception of removing the flange requirement for potential future use.]
I INTRODUCTION He:uup and cool down limit curves are calculated using lhe adjusted RT NOT (reference nil-ductility temperature) corresponding to the limiting belt line region m:iterial of the reilctor vessel. The adjusted RT Nor of the limiting material in the core region of the reactor vessel is determined by using the unirrildiated reactor vessel material fracture toughness properties.
estima1ing the radiation-induced flRT NOT* and adding a margin. The unirradia1ed RT Nl>T is designated as the higher of either the drop weight nil-ductility transition temperature (NDTI) or the 1empcra1ure al which the malerial exhibits at least 50 ft-lb of impact energy and 35-mil lateral expansion (normal to &he major working direction) minus 60°F. RT Nl>T increases as the material is exposed to fast-neutron radiation.
Therefore.
to find the most limiting RT NOT at any time period in the reactor's life, flRT NOT due to the radiation exposure associated with that rime period must be added to the unirradiated RT NOT (IRT NOT). The extent of 1he shift in RT NOT is enhanced by certoiin chemical clements (such as copper and nickel) present in reactor vessel steels. The Nucleilr Regul:uory Commission (NRC) has published a method for predicting radialion embriulement in Regulalory Guide 1.99, Revision 2, .. Radialion Embrillll!menl of Reactor Vessel Malerials.
1'1 Regulatory Guide 1.99, Revision 2, is used for lhe calculation of Adjusted Reference Tempcralure (ART) values (lRTNOT + .1.RT NM'+ margins for uncertainties) at the 1/4T and 3/4T locations, where Tis the thickness of the vessel at the belt line region measured from the clad/base metal interface.
The heatup and cooldown curves documented in this report were generaled using the most limiling ART values and the NRC approved methodology documented in WCAP-14040-NP-A, Revision 2 1"'1 , "Me1hodology Used to Develop Cold Overpressure Mitigating System Setpoints and RCS Heatup and Cooldown Limit Curves" wilh exception of the following:
I) The Oucnce values used in this report arc calculated nuence values (i.e. comply with Reg. Guide l.190). not the best estimate flucnce values. 2) The K1c crilical stress intensities are used in place of the K 1 , criticill stress inlensities.
This me1hodology is laken from approved ASME Code Case N-641m. 3)The 1996 Version of Appcndiit G to Sec1ion will be used rather than the 1989 version. WCAP-IS827 2 FRACTURE TOUGHNESS PROPERTIES The fracture-toughness propenies of the ferri1ic materials in 1he reactor coolant pressure boundary are determined in accordance wi1h the NRC Standard Review Plan 171* The bellline material properties of the H.B. Robinson Unit 2 reactor vessel is presen1ed in Table I. 2 Best estimate copper (Cu) and nickel (Ni) weight percent values used to calculate chemistry factors (CF) in accordance with Regulatory Guide 1.99, Revision 2, are provided in Table I. Addition:illy, surveillance capsule data is available for four capsules (Capsules S, V, T and X) already removed from lhe H.B. Robinson Unit 2 reactor vesse1. This l'IUr\'cillance capsule dala was ntso used lo cakuta1e CF values per Posilion 2.1 of Regulatory Guick 1.99, Rcvbion 2 in Table 4. These CF values are summarized in Table 5. The Regulalory Guide 1.99, Revision 2 methodology used lo develop the heatup and cooldown curves documented in this report is the same as that documented in WCAP-14040, Revision 2. Credibility Evalu:11ion Robinson surveillance program contains surveillance malerial from alJ three intermediate shell plates and from weld material fabricated from weld wire heat number W52 I 4, which is the same heat as the upper lo intermedia1e shell girth weld seam. In order to apply the surveillance data to such evaluations as developing ART values, you lirst have to evaluate whether or not the data is credible.
The procedures for cvalualing credibility are prescribed in Regulatory Guide 1.99, Rev. 2 and IOCFR50.61, along with guidance provided by the NRC at an industry meeting on February 12 111 & 13th, 1998. The credibility cvalualion for lhe Robinson data has already been performed under lhe Capsule X repon, WCAP-15805, and the results were as follows:
- Surveillance plate materials from lnlermediate Shell Plates WI0201-4 and Wl0201-6 were determined 10 be not credible.
- Surveillance plate ma1erials from Intermediate Shell Plate W 10201-5 was determined 10 be credible.
- Surveillance weld metal (Heat W5214) from Robinson only was dclermined to be not credible.
Note that there exists surveillance data of the same heat from Indian Point Units 2 and 3. lf this data were integrated with Robinson, the surveillance weld data would then be credible.
For conservatism, however, the Indian Point surveillance data will not be used. Robinson data alone produces a slightly lower chemistry factor via Position 2.1, but this is off set by the higher margin because of the credible data.
on the results above, only intennediate shell plate W10201-5 may use a reduced m3rgin when calculating ART via Position 2.1. All other surveillance data win use the full in determining margin and ART. WCAP-1.5827 TABLE I Summary of the Best Estimale Cu and Ni Weight Pcrccnl and Initial RT NOT Values for the H.B.

WCAP-1.5827 3 CRITERIA FOR ALLO\VABLE PRESSURE-TEl\1PERATURE RELATIONSHIPS 3.1 Overall Approach The ASME approach for calculating 1he allowable limit cun.*es for various heatup and cooldown rates specifies that lhe total stress intensity factor, K1o for the combined thermal and pressure stresses at any time during heatup or cooldown cannot be greater 1han the reference slress intensity factor, Kie. for the metal temperature at that time. K1c is obtained from the reference fracture toughness curve, defined in Code Case N-640, .. Alternative Reference Frac1ure Toughness for Development of PT Limit Curves for Section Xl12" 31 of the ASME G to Section XI. The K1c curve is given by the following equation:
where, (I) reference stress intensity factor as a function of the metal temperature T and the metal reference nit-ductility temperature RT NOT This K1c curve is based on the lower bound of static critical K 1 values measured as a function of temperature on specimens of SA-533 Grade B Class I, SA-508-1, SA-508-2, SA-508-3 steel. 3.2 Methodology ror Pressure-Temperature Limit Curve De,,*elopment The governing equation for the heatup-cooldown analysis is defined in Appendix G of Che ASME Code as follows: where, K 1 m = stress intensity factor caused by membrane (pressure) stress K 11 = stress intensity factor caused by the thermal gradients (2) K1c = reference stress intensity factor as a function of temperature relative to the RT NOT of the material C s::: 2.0 for Level A and Level B service limils C = 1.5 for hydrostatic and leak tesl conditions during which the reactor core is not critical WCAP-15827 7
For membrane 1cnsion, 1he corresponding K 1 for the postulated defect is: Kim= M,,,x(pR./t) where. Mm for an inside surface flaw is given by: 1.85 for .Ji < 2, 0.926 .fi for 2 S .fi S 3.464
- 3.21 for .fi > 3.464 Similarly.
Mm for an oulside surface flaw is given by: 1.77 for .Ji < 2, 0.893 .fi for 2 S JI S 3.464 , 3.09 for .Ji > 3.464 and p = internal pressure, Ri = vessel inner radius, and t =vessel wall thickness.
For bending stress. the corresponding K 1 for the postulated defect is: Kn. = Mb
- Maximum Slress, where M 11 is two-thirds of Mm 8 (3) The maximum K 1 produced by radial thermal gradienl for che po!itulated in!iide surface defecc of G-2120 is K 1 , = 0.953x JO.) x CR x tu. where CR is the cooldown rate in °F/hr .* or for a poslulated oulside surface defecl, K 14=0.753x10*
3 x HU x t 15 , where HU is the heatup rale in °f/hr. The through-wall temperature difference associated with the maximum thermal K 1 c:m be determined from Fig. G-2214-1.
The temperature at any radial distance from the vessel surface can be determined from Fig. G-2214-2 for the maximum thermal K 1* (:a) The m:aximum thermal K 1 relationship and the temperature relationship in Fig. G-2214-1 are applicable only for the conditions given in G-22 I 4.3(a)( I) and (2). (b) Alternatively, the K 1 for radial thermal gradient can be calculated for any thermal stress distribution and at any specified time during cooldown for a *A-thickness inside surface defect using the relationship:
K11 = (1.0359Co+
0.6322C1+0.4753C2+0.3855C3)
- /; (4) WCAP-15827 or similarly, Krr during heatup for a 'A-thickness outside surface defect using the relationi;hip:
K1, = ( l.043Co + o."630C1 + 0.481C2+0.40 I Cl)* Ji;; (5) where the coefficients Co. Ci. C 1 and Cl are dctennined from the thermal stress distribution at any specified time during the heatup or cooldown using the form: (6) and xis a variable that represents the radial distance from the appropriate (i.e., inside or outside) surface to any point on the crack front and a is the maltimum crack depth. 9 Note, that equations 3, 4 and 5 were implemented in the OPERLIM computer code, which is the program used to generate the pressure-temperature (P-T) limit curves. No other changes were made to 1he OPERLIM computer code with regard to P-T calculation methodology.
Therefore, the P-T curve methodology is unchanged from that described in WCAP-14040, "Methodology used lo Develop Cold Overpressure Mitigating System Setpoints and RCS Heatup and Cooldown Limit Curves" 161 Section 2.6 (equations 2.6.2-4 and 2.6.3-1) with the exceptions just described above. At any time during the heatup or cooldown transient, K1c is di:tennined by the metal temperature at the lip of a postulated naw at the I /4T and 3/4T location, the appropriate value for RT NOT* and the reference fracture toughness curve. The thermal stresses resulting from the temperature gradients through the vessel wall are calculated nnd then the corresponding (thermal) slress in1ensity factors, K 11 , for the reforence naw are computed.
From Equation 2, the pressure stress intensity factors are obtained and, from these, the allowable pressures are calculated.
For the calculation of the allowable pressure versus coolant temperature during cooldown, lhe reference naw of Appendix G to the ASME Code is assumed to exist at the inside of the vessel wall. During cooldown, the controlling location of the naw is always at lhe inside of the wall because the thennal gradients produce tensile stresses nt the inside, which increase with increasing cooldown rates. Allowahle pressure-tempcrarurc relations nre generated for both stendy*stare and finite cooldown rate situations.
From these relations, composite limit curves are constructed for ench cooldown rate of interest.
The use or the composite curve in the cooldown analysis is necessary because control of the cooldown procedure is based on the measurement of reactor coofant tempcrarure, whereas the limiting pressure is actually dependent on the material temperature at the tip of the assumed naw. During cooldown, the l/4T vessel location is at a higher temperature than the Ouid adjacent to the vessel inner diameter.
This condition.
of course, is nor true for the steady-state situation.
It follows that, at any given reactor coolant temperature, the 41T (temperature) developed during cooldown results in a higher value of Kie at lhe If.ff location for finite cooldown rates lhan for steady-state operation.
furthennore, if conditions exist so that the increase in Kk exceeds K 11 , the calculated allowable pressure during c:ooldown will be greater than the Mcady-state
\'alue. WCAP-15827 The above procedures are necdl!d bccau!.e there is no direct control on temperature at the l/4T location and, lherefore, allowable may be violated if the rate of cooling is decreased at various inlervals along a cooldown ramp. The ui.e of the composile curve eliminates this problem and ensures conserv;uive opera1ion of the sy!>lem for 1he entire cooldown period. 10 Three separate calculations are required 10 de1ermine 1he limit curves for finite heatup rates. As is done in the cooldown analysis.
allowable pre!.sure-temperature relationships are developed for conditions as well as finite heat up rate conditions assuming the presence of a l/4T defect at the inside of the wall. The heatup rc:sulls in compressive stresses at the inside surf ace that alleviate the tensile stresses produced by internal pressure.
The metal temperature at the crack tip lags the coolant tempera1Ure:
therefore, lhe K 1 c for the l/4T crnck Juring heatup is lower than lhe Kie for lhe l/4T crack during state conditions al the same coolanl temperature.
During hcalup, especially al 1he end of lhc lransienl, conditions may exist so 1hat lhe effec1s of compressive 1hennal stresses and lower K1c values do not offset each other, and lhe pressure-temperature curve based on steady-Mate conditions no longer represents a lower bound of all similar curves for finite he:uup rates when the l/4T naw is considered.
Therefore, both cases have to be analyzed in order to ensure that al any coolant temperature the lower value of the allowable pressure calculated for !lteady-!>tatc and finite healup rates is obtained.
The second ponion of the heatup analysis concerns the calculation of the pressure-temperature limitations for the case in which a l/4T Oaw located at the l/4T location from the outside surface is assumed. Unlike the situation at the \'e!ii.el inside the thermal gradients established at the outside surface during hca1up produce Mre!.i.es which are tensile in nature and therefore lend to reinforce any pressure stresses present. These thermal arc dependent on both the rate of hcatup and the time (or coolant temperature) along the hcatup ramp. Since the thennal stresses at the outside arc tensile and increase with increasing heatup rates. each heatup rate must be an:ilyzed on an individu:il basis. Following the gener:ition of pressure-temperature curves for both the Meady-state and finite heatup rate situations, the final limit cur\'cs are produced by a
curve based on a point comparison of the and finite heat up rate data. At any given temperature, the aUowable is laken to be the lesser of the three \'alues laken from the curves under consideration.
The use of the composile curve is necessary to set conservative heatup limilations because it is possible for conditions to exist wherein. over the couri.e of the heatup ramp, the controlling condition switches from the inside to the outside. and the pressure limil mu!lt at all times be based on analysis of the most critical criterion.

WCAP*l5827 4 CALCULATION OF ADJUSTED REFERENCE TEMPERATURE From Regulatory Guide 1.99, Revision 2, the adjusled reference temperature (ART) for each material in the bchline region is given by the following expression:
ART= lniti:lf RT Nt>f +ART 1111>r +Margin (7) lni1ial RT NOT is Che reference temperature for the unirradialcd malerial as defined in paragraph NB-2331 of Section Ill of the ASME Boiler and Pressure Vessel Codelll 1* If measured values of initial RT NOT for the material in question arc not avallable, generic mean values for tha' class of material may be used if there are sufficient test results 10 eslablish a mean and standard deviation for the class. II ART NOT is the mean value or the adjustment in reference tcmpcralurc caused by irradiation and should be calculated as follows: To calculate ART NOT at any depth (e.g., at l/4T or 3/4T), the following formula must first be used to attenuate the flucnce at the specific depth. (8) (9) where x inches (vessel bel1Jine thickness is 9.313 inches) is the dcp1h into the vessel wall measured from the vessel clad/base metal interface.
The resulrant Ouence is then placed in Equation 8 to calculate the ART Nor at the specific depth. The Westinghouse Radiation Engineering and Analysio; Group evaluated the vessel nuence projections in WCAP-15805, which were updated toreOcct a total power uprate of 1.77r to 2339 Mw. They are presented in a condensed version in Tabk S of this rcpon. The evaluation used the ENDF/B-VJ scattering cross-section data set.

WCAP-15827 5 HEATUP AND COOLDO\VN PRESSURE-TEMPERATURE Lll\fIT CURVES Pressure-temperature limit curves for nonnal heatup and cooldown of the primary reactor coolant system have been caiculated for the pressure and temperature in the reactor vessel beltlinc region using the methods discussed in Sections 3.0 and 4.0 of this report. This approved methodology is also presented in WCAP-14040-NP*A, Revision 2 with exception of those items discussed in Section 1 of this report. 29 Figures I, 3, S, 7 and 9 present the limiting heatup curves \\ithout margins for possible instrumentation errors using heatup rates of 60 and I00°F/hr applicable for the first 30, 35, 40, 45 and 50 EFPYs, respectively.
These curves were generated using the 1996 ASME Code Section XI, Appendix.
G with the limiting plate ARTs in combination
\\ith ASME Code Case N-588 and the limiting circ weld ARTs. The curves produced using the limiting plate ARTs are primarily bounding throughout the heatup curves, however there arc instances that the circ weld becomes limiting at higher temperatures
{See bolded values In rhe data tables). Figures 2. 4, 6, 8 and 10 present the limiting cooldO\\n curves \\ithout margins for possible instrumentation errors using cooldown rates of 0, 20, 40, 60 and 100°f/hr applicable for 30, 35, 40, 45 and 50 EFPYs, respectively.
Again. these curves were generated using the 1996 ASME Code Section XI, Appendix G with the limiting pl3te ARTs in combination v.ith ASME Code Case N-588 and the limiting circ weld ARTs. The curves produced using the limiting plate ARTs are primarily bounding throughout the cooldown curves, however there arc instances that the circ weld becomes limiting at higher temperatures (See holdcd values in the data tables). Allowable combination of temperature and pressure for specific temperature change rates arc below and to the right of the limit lines shown in Figures I through 10. This is in addition to other criteria which must be met before the rC3ctor is made critical, as discussed below in the following paragraphs.
The reactor must not be made critical until pressure-temperature combinations arc to the right of the criticality limit line shown in Figures I, 3, 5, 7 and 9. The straight-line portion of the criticality limit is at the minimum permissible temperature for the 2485 psig inservicc hydrostatic test as required by Appendix G to 10 CFR Part 50. The governing equ:ition for the hydrostatic test is defined in Code Case N-6401 2 1 (approved in February 1999) as follows: where, K1m is the stress intensity factor covered by membrane (pressure) stress, Kie= 33.2 + 20.734 cl 002 CT*RTNDT>I, T is the minimum permissible metal temperature, and RT NOT is the metal reference temperature.
The criticality limit curve specifics pressure-temperature limits for core operation to provide additional margin during actual power production as specified in Reference
- 14. The pressure-temperature limits for WCAP*IS827 30 core operation (except for low power physics tests) arc that the re.'.lctor vessel must be at a temperature equal to or higher than the minimum temperature required for the inscrvice hydrostatic test. and at least 40°F higher the minimum pcnnissible temperature in the corresponding pressure-temperature curve for hcatup and cooldown calculated as described in Section 3.0 of this report. for the hcatup and coo1down curves without margins for instrumentation errors, the minimum temperatures for the in service hydrostatic 1e:tk tests for the H.B. Robinson Unit 2 reactor vessel at 30, 35, 40, 45 and 50 EFPY are 214°F, 216°F, 2 l 8°F, 2 J 9°F and 221°F, respectively.
The vertical line drawn from these points on the tcmperaturc curve, intersecting a curve 40°f higher than the pressure-temperature limit curve, constitutes the limit for core operation for the rC3ctor vessel. Figures 1 through I 0 define all of the above limits for ensuring prevention of nonductilc fuilure for the H.B. Robinson Unit 2 reactor vessel for various EFPYs. The data points used for the he.1tup and cooldown pressure-temperature limit curves shoY.n in Figures I through 10 arc presented in Tables 19 through 28. The balded values arc those limited by the girth weld using the "Circ-FJaw" Methodology.
The non-bolded values arc those limited by the Upper shell Plate using the standard "Axial-Flaw" Methodology from the 1996 version of the ASME Code Section XI, Appendix G WCAP-15827 31 MATERIAL PROPERTY BASIS LIMITING MATERIAL:

1.0 DESCRIPTION
AND BASIS OF PROPOSED CHANGE 1.1 Description of Proposed Change Appendix A, Technical Specifications (TS), to Renewed Operating License No. DPR-23, for H. B. Robinson Steam Electric Plant, Unit No. 2 (HBRSEP2), establishes the Limiting Condition for Operation (LCO) requirements for reactor coolant system (RCS) pressure and temperature (PIT) limits. Specifically, the LCO states that the RCS pressure, RCS temperature, and RCS heatup and cooldown rates shall be maintained within the limits specified in Figures 3.4.3-1 and 3.4.3-2. Figures 3.4.3-1 and 3.4.3-2 contain PIT limit curves for heatup, cooldown, inservice leak and hydrostatic (ISLH) testing, and data for the maximum rate of change of reactor coolant temperature.
Each PIT limit curve defines an acceptable region for operation.
The curves are used during heatup and cooldown maneuvering, by monitoring and comparing pressure and temperature indications to the applicable curve to ensure that operation is within the allowable region. The proposed change replaces TS Section 3.4.3, Figures 3.4.3-1 and 3.4.3-2, with updated curves (see the attached markup of TS pages and retyped TS pages) that are applicable up to 50 effective full power years (EFPY). This is necessary since the current Figures 3.4.3-1 and 3.4.3-2 are applicable to 35 EFPY, which is projected to be reached at the start of cycle 31. 1.2 Basis For Proposed Change The technical basis for the proposed revision to the heatup and cooldown limits is provided in the attached Westinghouse report, WCAP-15827, "H. B. Robinson Unit 2 Heatup and Cooldown Limit Curves for Normal Operation." The fluence values used in these analyses were updated and documented in WCAP-15805, "Analysis of Capsule X from the Carolina Power and Light Company H. B. Robinson Unit 2 Reactor Vessel Radiation Surveillance Program," which was previously submitted to the NRC by letter, dated April 25, 2002. As explained in the attached WCAP-15827 report, the heatup and cooldown curves were generated using the most limiting material adjusted reference temperature (ART) values and the NRG-approved methodology documented in WCAP-14040-NP-A, Revision 2, "Methodology Used to Develop Cold Overpressure Mitigating System Setpoints and RCS Heatup and Cooldown Limit Curves," with the exception of the following:
The fluence values are calculated fluence values (i.e., comply with Regulatory Guide 1.190), and are not the best-estimate fluence values. K 1 c (which is the material toughness property measured in terms of stress intensity factor, Ki. which will lead to non-ductile crack propagation) is used in place of K 1 a (which is the critical value of the stress intensity factor, K1, for crack arrest as a function of temperature).
This methodology is consistent with the approved ASME Code Case N-641.
U. S. Nuclear Regulatory Commission Attachment 1 to Serial: RNP-RA/15-0083 Page 3 of 5 The 1996 Version of Appendix G to ASME Section XI was used in lieu of the 1989 version. Additionally, the proposed heatup and cooldown limits were further adjusted by +20°F and -80 psig to account for instrument error, which is consistent with the current licensing basis. The normal shift of the Prr limit curves as irradiation time increases is toward lower pressures for a given temperature.
The pressure-temperature curves for 50 EFPY were developed using the "axial-flaw" methodology with the most limiting " axial-flaw" ARTs and the "circ-flaw" methodology (Code Case N-641) with the most limiting "circ-flaw" ARTs. This allows higher pressures at a given temperature, and the limit curves shift to lower temperatures and higher pressures upon first use of the methodology.
This method has been accepted by the NRC in the past as an exemption to ASME Section XI, and in April 2004, the NRC published Regulatory Issue Summary 2004-04, "Use of Code Cases N-588, N-640, and N-641 in Developing Pressure-Temperature Operating Limits," which allows the use of the Code Case methodology with no need for an exemption application. Review of the low temperature overpressure protection limits confirmed that no changes are required as a result of the revised reactor pressure vessel analyses and limits. Since the proposed RCS Prr limits are based on applicable NRG-approved methodology, the proposed amendment will continue to maintain appropriate limits for the HBRSEP2 RCS up to 50 EFPY. 2.0 REGULATORY ANALYSIS 2.1 No Significant Hazards Consideration Determination As required by 10 CFR 50.91 (a)(1 ), this analysis is provided to demonstrate that the proposed license amendment does not involve a significant hazard. Conformance of the proposed amendment to the standards for a determination of no significant hazards, as defined in 10 CFR 50.92, is shown in the following: 1) Does the proposed license amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
No. The proposed RCS Prr limits are based on NRG-approved methodology and will cont i nue to maintain appropriate limits for the HBRSEP2 RCS up to 50 EFPY. These changes provide appropriate limits for pressure and temperature during heatup and cooldown of the RCS, thus ensuring that the probability of RCS failure is maintained acceptably low. These limits are not directly related to the consequences of accidents.
Therefore , the proposed amendment does not result in an increase in the probability or consequences of an accident previously evaluated.
U. S. Nuclear Regulatory Commission Attachment 1 to Serial: RNP-RA/15-0083 Page 4 of 5 2) Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
No. The proposed changes will continue to ensure that the RCS will be maintained within appropriate pressure and temperature limits during heatup and cooldown.
No physical changes to the HBRSEP2 systems, structures, or components are being implemented. There are no new or different accident initiators or sequences being created by the proposed Technical Specifications changes. Therefore, these changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3) Does the proposed change involve a significant reduction in margin of safety? No. The proposed changes ensure that the margin of safety for the fission product barriers protected by these functions will continue to be maintained.
This conclusion is based on use of the applicable NRC-approved methodology for developing and establishing the proposed RCS PIT limits. Therefore, these changes do not involve a significant reduction in the margin of safety. Based on the preceding analysis, it is concluded that the replacement of TS Section 3.4.3, Figures 3.4.3-1 and 3.4.3-2, with updated curves that are applicable up to 50 EFPY does not involve a significant hazards consideration finding as defined in 10 CFR 50.92. 3.0 ENVIRONMENTAL ANALYSIS 10 CFR 51.22(c)(9) provides criteria for identification of licensing and regulatory actions for categorical exclusion from performing an environmental assessment.
A proposed change for an operating license for a facility requires no environmental assessment if operation of the facility in accordance with the proposed change would not (i) involve a significant hazards consideration; (ii) result in a significant change in the types or significant increases in the amounts of any effluents that may be released offsite; (iii) result in a significant increase in individual or cumulative occupational radiation exposure.
Duke Energy Progress, Inc., has reviewed this request and determined that the proposed change meets 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 needs to be prepared in connection with the issuance of the amendment.
The basis for this determination is as follows: Proposed Change The proposed change will revise the RCS pressure and temperature limits by replacing Technical Specifications Section 3.4.3, "RCS Pressure and Temperature (PIT) Limits," Figures 3.4.3-1 and 3.4.3-2, with figures that are applicable up to 50 EFPY.
U. S. Nuclear Regulatory Commission Attachment 1 to Serial: RNP-RA/15-0083 Page 5 of 5 The proposed changes meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) for the following reasons: 1) As demonstrated in the No Significant Hazards Consideration Determination, the proposed changes do not involve a significant hazards consideration.
- 2) The proposed changes revise the RCS pressure and temperature limits by replacing Technical Specifications Section 3.4.3, "RCS Pressure and Temperature (PIT) Limits," Figures 3.4.3-1 and 3.4.3-2, with figures that are applicable up to 50 EFPY. These changes do not affect the generation or control of effluents.
Therefore, the proposed changes will not result in a significant change in the types or significant increases in the amounts of any effluents that may be released offsite. 3) The proposed changes, as previously described, do not affect any parameters that would cause an increase in occupational radiation exposure. There are no proposed physical changes to the facility or any process changes that would result in additional radiation exposure.
Therefore, the proposed changes will not result in a significant increase in individual or cumulative occupational radiation exposure.

SUMMARY
This report provides the methodology and results of the generation ofheatup and cooldown pressure temperature limit curves for nonn:il operation of the H.B. Robinson Unit 2 reactor vessel. In addition, the vessel wall temperature dati is documented herein under the Appendices.
The PT curves were generated based on the latest available reactor vessel infommtion and Ouenees {WCAP-1580S)fll, which were up<bted to reflect actual power realized from the R021 uprate. The new H.B. Robinson Unit 2 heatup and cooldo\\11 pressure-temperature limit curves were generated using ASME Code Case N-6411 21 (which allows the use of the Kie methodology and "Circ. Flaw" methodology) and the a.'tial flaw methodology of the 1995 ASME Code,Section XI through the 1996 Addcndat 3 l. It should be noted that H.B. Robinson was limited at the l/4T and 3/4T locations by the upper to intermediate shell circumferential weld with exception to the 3/4T location at 30 EFPY (Limited here by the upper shell plate Wl0201*1).
The limiting axial material was the upper shell plate Wl0201*1.
The pressure-temperature (PT) limit curves presented in Section S and Appendix A arc developed using the "axial-flaw
methodology with the most limiting "a"<i:il-flaw" adjusted reference temperatures (ARTs), and the "Circ Flaw" Methodology (ASME Code Case N-641. formerly known as N-Sssl*I) with the mQfil limiting "Circ. Flaw" ART values. The "a.'tial-flaw" ART values produce a more limiting PT curve overall with exception to the higher temperatures where at a ccrt3in point, depending on the EFPY, the curve could switch from "axial-flaw" limited to a "circ-flaw" limited curve. When and where this occurs is noted within the data tables for each specific PT-limit curve. [Note that the PT limit curves of Appendix A arc the same as those in Section S, with exception of removing the flange requirement for potential future use.]
I INTRODUCTION He:uup and cool down limit curves are calculated using lhe adjusted RT NOT (reference nil-ductility temperature) corresponding to the limiting belt line region m:iterial of the reilctor vessel. The adjusted RT Nor of the limiting material in the core region of the reactor vessel is determined by using the unirrildiated reactor vessel material fracture toughness properties.
estima1ing the radiation-induced flRT NOT* and adding a margin. The unirradia1ed RT Nl>T is designated as the higher of either the drop weight nil-ductility transition temperature (NDTI) or the 1empcra1ure al which the malerial exhibits at least 50 ft-lb of impact energy and 35-mil lateral expansion (normal to &he major working direction) minus 60°F. RT Nl>T increases as the material is exposed to fast-neutron radiation.
Therefore.
to find the most limiting RT NOT at any time period in the reactor's life, flRT NOT due to the radiation exposure associated with that rime period must be added to the unirradiated RT NOT (IRT NOT). The extent of 1he shift in RT NOT is enhanced by certoiin chemical clements (such as copper and nickel) present in reactor vessel steels. The Nucleilr Regul:uory Commission (NRC) has published a method for predicting radialion embriulement in Regulalory Guide 1.99, Revision 2, .. Radialion Embrillll!menl of Reactor Vessel Malerials.
1'1 Regulatory Guide 1.99, Revision 2, is used for lhe calculation of Adjusted Reference Tempcralure (ART) values (lRTNOT + .1.RT NM'+ margins for uncertainties) at the 1/4T and 3/4T locations, where Tis the thickness of the vessel at the belt line region measured from the clad/base metal interface.
The heatup and cooldown curves documented in this report were generaled using the most limiling ART values and the NRC approved methodology documented in WCAP-14040-NP-A, Revision 2 1"'1 , "Me1hodology Used to Develop Cold Overpressure Mitigating System Setpoints and RCS Heatup and Cooldown Limit Curves" wilh exception of the following:
I) The Oucnce values used in this report arc calculated nuence values (i.e. comply with Reg. Guide l.190). not the best estimate flucnce values. 2) The K1c crilical stress intensities are used in place of the K 1 , criticill stress inlensities.
This me1hodology is laken from approved ASME Code Case N-641m. 3)The 1996 Version of Appcndiit G to Sec1ion will be used rather than the 1989 version. WCAP-IS827 2 FRACTURE TOUGHNESS PROPERTIES The fracture-toughness propenies of the ferri1ic materials in 1he reactor coolant pressure boundary are determined in accordance wi1h the NRC Standard Review Plan 171* The bellline material properties of the H.B. Robinson Unit 2 reactor vessel is presen1ed in Table I. 2 Best estimate copper (Cu) and nickel (Ni) weight percent values used to calculate chemistry factors (CF) in accordance with Regulatory Guide 1.99, Revision 2, are provided in Table I. Addition:illy, surveillance capsule data is available for four capsules (Capsules S, V, T and X) already removed from lhe H.B. Robinson Unit 2 reactor vesse1. This l'IUr\'cillance capsule dala was ntso used lo cakuta1e CF values per Posilion 2.1 of Regulatory Guick 1.99, Rcvbion 2 in Table 4. These CF values are summarized in Table 5. The Regulalory Guide 1.99, Revision 2 methodology used lo develop the heatup and cooldown curves documented in this report is the same as that documented in WCAP-14040, Revision 2. Credibility Evalu:11ion Robinson surveillance program contains surveillance malerial from alJ three intermediate shell plates and from weld material fabricated from weld wire heat number W52 I 4, which is the same heat as the upper lo intermedia1e shell girth weld seam. In order to apply the surveillance data to such evaluations as developing ART values, you lirst have to evaluate whether or not the data is credible.
The procedures for cvalualing credibility are prescribed in Regulatory Guide 1.99, Rev. 2 and IOCFR50.61, along with guidance provided by the NRC at an industry meeting on February 12 111 & 13th, 1998. The credibility cvalualion for lhe Robinson data has already been performed under lhe Capsule X repon, WCAP-15805, and the results were as follows:
- Surveillance plate materials from lnlermediate Shell Plates WI0201-4 and Wl0201-6 were determined 10 be not credible.
- Surveillance plate ma1erials from Intermediate Shell Plate W 10201-5 was determined 10 be credible.
- Surveillance weld metal (Heat W5214) from Robinson only was dclermined to be not credible.
Note that there exists surveillance data of the same heat from Indian Point Units 2 and 3. lf this data were integrated with Robinson, the surveillance weld data would then be credible.
For conservatism, however, the Indian Point surveillance data will not be used. Robinson data alone produces a slightly lower chemistry factor via Position 2.1, but this is off set by the higher margin because of the credible data.
on the results above, only intennediate shell plate W10201-5 may use a reduced m3rgin when calculating ART via Position 2.1. All other surveillance data win use the full in determining margin and ART. WCAP-1.5827 TABLE I Summary of the Best Estimale Cu and Ni Weight Pcrccnl and Initial RT NOT Values for the H.B.

(g) Sec Tahle 4. WCAP-15827 The chemistry factors were calculated using Regulatory Guide 1.99 Revision 2, Posit ions I.I and 2.1. Position 1.1 uses the Tables from the Reg. Guide along with the best estim.1te copper and nickel weight percents.
Position 2.1 uses the surveillance capsule data from all capsules withdrawn to dale. The Ouence values used to determine the CFs in Table 4 are the calculated nucnce values at the surveillance capsule locations.
The measured ART Nor values for the weld data were adjusted for chemistry using the ratio procedure given in Position 2.1 of Regulatory Guide 1.99, Revision 2. All calculated Ouence values (capsule and projections) for H.B. Robinson Unit 2 were updated and documented in WCAP-15805 111* These fluences were calculated using the ENDF/B-VI scattering section data set.

WCAP-1.5827 3 CRITERIA FOR ALLO\VABLE PRESSURE-TEl\1PERATURE RELATIONSHIPS 3.1 Overall Approach The ASME approach for calculating 1he allowable limit cun.*es for various heatup and cooldown rates specifies that lhe total stress intensity factor, K1o for the combined thermal and pressure stresses at any time during heatup or cooldown cannot be greater 1han the reference slress intensity factor, Kie. for the metal temperature at that time. K1c is obtained from the reference fracture toughness curve, defined in Code Case N-640, .. Alternative Reference Frac1ure Toughness for Development of PT Limit Curves for Section Xl12" 31 of the ASME G to Section XI. The K1c curve is given by the following equation:
where, (I) reference stress intensity factor as a function of the metal temperature T and the metal reference nit-ductility temperature RT NOT This K1c curve is based on the lower bound of static critical K 1 values measured as a function of temperature on specimens of SA-533 Grade B Class I, SA-508-1, SA-508-2, SA-508-3 steel. 3.2 Methodology ror Pressure-Temperature Limit Curve De,,*elopment The governing equation for the heatup-cooldown analysis is defined in Appendix G of Che ASME Code as follows: where, K 1 m = stress intensity factor caused by membrane (pressure) stress K 11 = stress intensity factor caused by the thermal gradients (2) K1c = reference stress intensity factor as a function of temperature relative to the RT NOT of the material C s::: 2.0 for Level A and Level B service limils C = 1.5 for hydrostatic and leak tesl conditions during which the reactor core is not critical WCAP-15827 7
For membrane 1cnsion, 1he corresponding K 1 for the postulated defect is: Kim= M,,,x(pR./t) where. Mm for an inside surface flaw is given by: 1.85 for .Ji < 2, 0.926 .fi for 2 S .fi S 3.464
- 3.21 for .fi > 3.464 Similarly.
Mm for an oulside surface flaw is given by: 1.77 for .Ji < 2, 0.893 .fi for 2 S JI S 3.464 , 3.09 for .Ji > 3.464 and p = internal pressure, Ri = vessel inner radius, and t =vessel wall thickness.
For bending stress. the corresponding K 1 for the postulated defect is: Kn. = Mb
- Maximum Slress, where M 11 is two-thirds of Mm 8 (3) The maximum K 1 produced by radial thermal gradienl for che po!itulated in!iide surface defecc of G-2120 is K 1 , = 0.953x JO.) x CR x tu. where CR is the cooldown rate in °F/hr .* or for a poslulated oulside surface defecl, K 14=0.753x10*
3 x HU x t 15 , where HU is the heatup rale in °f/hr. The through-wall temperature difference associated with the maximum thermal K 1 c:m be determined from Fig. G-2214-1.
The temperature at any radial distance from the vessel surface can be determined from Fig. G-2214-2 for the maximum thermal K 1* (:a) The m:aximum thermal K 1 relationship and the temperature relationship in Fig. G-2214-1 are applicable only for the conditions given in G-22 I 4.3(a)( I) and (2). (b) Alternatively, the K 1 for radial thermal gradient can be calculated for any thermal stress distribution and at any specified time during cooldown for a *A-thickness inside surface defect using the relationship:
K11 = (1.0359Co+
0.6322C1+0.4753C2+0.3855C3)
- /; (4) WCAP-15827 or similarly, Krr during heatup for a 'A-thickness outside surface defect using the relationi;hip:
K1, = ( l.043Co + o."630C1 + 0.481C2+0.40 I Cl)* Ji;; (5) where the coefficients Co. Ci. C 1 and Cl are dctennined from the thermal stress distribution at any specified time during the heatup or cooldown using the form: (6) and xis a variable that represents the radial distance from the appropriate (i.e., inside or outside) surface to any point on the crack front and a is the maltimum crack depth. 9 Note, that equations 3, 4 and 5 were implemented in the OPERLIM computer code, which is the program used to generate the pressure-temperature (P-T) limit curves. No other changes were made to 1he OPERLIM computer code with regard to P-T calculation methodology.
Therefore, the P-T curve methodology is unchanged from that described in WCAP-14040, "Methodology used lo Develop Cold Overpressure Mitigating System Setpoints and RCS Heatup and Cooldown Limit Curves" 161 Section 2.6 (equations 2.6.2-4 and 2.6.3-1) with the exceptions just described above. At any time during the heatup or cooldown transient, K1c is di:tennined by the metal temperature at the lip of a postulated naw at the I /4T and 3/4T location, the appropriate value for RT NOT* and the reference fracture toughness curve. The thermal stresses resulting from the temperature gradients through the vessel wall are calculated nnd then the corresponding (thermal) slress in1ensity factors, K 11 , for the reforence naw are computed.
From Equation 2, the pressure stress intensity factors are obtained and, from these, the allowable pressures are calculated.
For the calculation of the allowable pressure versus coolant temperature during cooldown, lhe reference naw of Appendix G to the ASME Code is assumed to exist at the inside of the vessel wall. During cooldown, the controlling location of the naw is always at lhe inside of the wall because the thennal gradients produce tensile stresses nt the inside, which increase with increasing cooldown rates. Allowahle pressure-tempcrarurc relations nre generated for both stendy*stare and finite cooldown rate situations.
From these relations, composite limit curves are constructed for ench cooldown rate of interest.
The use or the composite curve in the cooldown analysis is necessary because control of the cooldown procedure is based on the measurement of reactor coofant tempcrarure, whereas the limiting pressure is actually dependent on the material temperature at the tip of the assumed naw. During cooldown, the l/4T vessel location is at a higher temperature than the Ouid adjacent to the vessel inner diameter.
This condition.
of course, is nor true for the steady-state situation.
It follows that, at any given reactor coolant temperature, the 41T (temperature) developed during cooldown results in a higher value of Kie at lhe If.ff location for finite cooldown rates lhan for steady-state operation.
furthennore, if conditions exist so that the increase in Kk exceeds K 11 , the calculated allowable pressure during c:ooldown will be greater than the Mcady-state
\'alue. WCAP-15827 The above procedures are necdl!d bccau!.e there is no direct control on temperature at the l/4T location and, lherefore, allowable may be violated if the rate of cooling is decreased at various inlervals along a cooldown ramp. The ui.e of the composile curve eliminates this problem and ensures conserv;uive opera1ion of the sy!>lem for 1he entire cooldown period. 10 Three separate calculations are required 10 de1ermine 1he limit curves for finite heatup rates. As is done in the cooldown analysis.
allowable pre!.sure-temperature relationships are developed for conditions as well as finite heat up rate conditions assuming the presence of a l/4T defect at the inside of the wall. The heatup rc:sulls in compressive stresses at the inside surf ace that alleviate the tensile stresses produced by internal pressure.
The metal temperature at the crack tip lags the coolant tempera1Ure:
therefore, lhe K 1 c for the l/4T crnck Juring heatup is lower than lhe Kie for lhe l/4T crack during state conditions al the same coolanl temperature.
During hcalup, especially al 1he end of lhc lransienl, conditions may exist so 1hat lhe effec1s of compressive 1hennal stresses and lower K1c values do not offset each other, and lhe pressure-temperature curve based on steady-Mate conditions no longer represents a lower bound of all similar curves for finite he:uup rates when the l/4T naw is considered.
Therefore, both cases have to be analyzed in order to ensure that al any coolant temperature the lower value of the allowable pressure calculated for !lteady-!>tatc and finite healup rates is obtained.
The second ponion of the heatup analysis concerns the calculation of the pressure-temperature limitations for the case in which a l/4T Oaw located at the l/4T location from the outside surface is assumed. Unlike the situation at the \'e!ii.el inside the thermal gradients established at the outside surface during hca1up produce Mre!.i.es which are tensile in nature and therefore lend to reinforce any pressure stresses present. These thermal arc dependent on both the rate of hcatup and the time (or coolant temperature) along the hcatup ramp. Since the thennal stresses at the outside arc tensile and increase with increasing heatup rates. each heatup rate must be an:ilyzed on an individu:il basis. Following the gener:ition of pressure-temperature curves for both the Meady-state and finite heatup rate situations, the final limit cur\'cs are produced by a
curve based on a point comparison of the and finite heat up rate data. At any given temperature, the aUowable is laken to be the lesser of the three \'alues laken from the curves under consideration.
The use of the composile curve is necessary to set conservative heatup limilations because it is possible for conditions to exist wherein. over the couri.e of the heatup ramp, the controlling condition switches from the inside to the outside. and the pressure limil mu!lt at all times be based on analysis of the most critical criterion.

WCAP*l5827 4 CALCULATION OF ADJUSTED REFERENCE TEMPERATURE From Regulatory Guide 1.99, Revision 2, the adjusled reference temperature (ART) for each material in the bchline region is given by the following expression:
ART= lniti:lf RT Nt>f +ART 1111>r +Margin (7) lni1ial RT NOT is Che reference temperature for the unirradialcd malerial as defined in paragraph NB-2331 of Section Ill of the ASME Boiler and Pressure Vessel Codelll 1* If measured values of initial RT NOT for the material in question arc not avallable, generic mean values for tha' class of material may be used if there are sufficient test results 10 eslablish a mean and standard deviation for the class. II ART NOT is the mean value or the adjustment in reference tcmpcralurc caused by irradiation and should be calculated as follows: To calculate ART NOT at any depth (e.g., at l/4T or 3/4T), the following formula must first be used to attenuate the flucnce at the specific depth. (8) (9) where x inches (vessel bel1Jine thickness is 9.313 inches) is the dcp1h into the vessel wall measured from the vessel clad/base metal interface.
The resulrant Ouence is then placed in Equation 8 to calculate the ART Nor at the specific depth. The Westinghouse Radiation Engineering and Analysio; Group evaluated the vessel nuence projections in WCAP-15805, which were updated toreOcct a total power uprate of 1.77r to 2339 Mw. They are presented in a condensed version in Tabk S of this rcpon. The evaluation used the ENDF/B-VJ scattering cross-section data set. This is with methods presented in WCAP-14Q.i0-NP-A, Methodology Used to Develop Cold Overpressure Mitigating Sysrem Sctpoints and RCS Hcatup ond Cooldown Limit Curves". Table S contains lhe calculated vessel surface nucnces values al various azimuthal locations, and in some instances at various longitudinal locations.

Conrained in Table 18 is a summary of lhe limiting ARTs to be used in the generation of the H.B. Robinson Unit 2 reactor vessel heatup and cooldown curves.

WCAP-15827 5 HEATUP AND COOLDO\VN PRESSURE-TEMPERATURE Lll\fIT CURVES Pressure-temperature limit curves for nonnal heatup and cooldown of the primary reactor coolant system have been caiculated for the pressure and temperature in the reactor vessel beltlinc region using the methods discussed in Sections 3.0 and 4.0 of this report. This approved methodology is also presented in WCAP-14040-NP*A, Revision 2 with exception of those items discussed in Section 1 of this report. 29 Figures I, 3, S, 7 and 9 present the limiting heatup curves \\ithout margins for possible instrumentation errors using heatup rates of 60 and I00°F/hr applicable for the first 30, 35, 40, 45 and 50 EFPYs, respectively.
These curves were generated using the 1996 ASME Code Section XI, Appendix.
G with the limiting plate ARTs in combination
\\ith ASME Code Case N-588 and the limiting circ weld ARTs. The curves produced using the limiting plate ARTs are primarily bounding throughout the heatup curves, however there arc instances that the circ weld becomes limiting at higher temperatures
{See bolded values In rhe data tables). Figures 2. 4, 6, 8 and 10 present the limiting cooldO\\n curves \\ithout margins for possible instrumentation errors using cooldown rates of 0, 20, 40, 60 and 100°f/hr applicable for 30, 35, 40, 45 and 50 EFPYs, respectively.
Again. these curves were generated using the 1996 ASME Code Section XI, Appendix G with the limiting pl3te ARTs in combination v.ith ASME Code Case N-588 and the limiting circ weld ARTs. The curves produced using the limiting plate ARTs are primarily bounding throughout the cooldown curves, however there arc instances that the circ weld becomes limiting at higher temperatures (See holdcd values in the data tables). Allowable combination of temperature and pressure for specific temperature change rates arc below and to the right of the limit lines shown in Figures I through 10. This is in addition to other criteria which must be met before the rC3ctor is made critical, as discussed below in the following paragraphs.
The reactor must not be made critical until pressure-temperature combinations arc to the right of the criticality limit line shown in Figures I, 3, 5, 7 and 9. The straight-line portion of the criticality limit is at the minimum permissible temperature for the 2485 psig inservicc hydrostatic test as required by Appendix G to 10 CFR Part 50. The governing equ:ition for the hydrostatic test is defined in Code Case N-6401 2 1 (approved in February 1999) as follows: where, K1m is the stress intensity factor covered by membrane (pressure) stress, Kie= 33.2 + 20.734 cl 002 CT*RTNDT>I, T is the minimum permissible metal temperature, and RT NOT is the metal reference temperature.
The criticality limit curve specifics pressure-temperature limits for core operation to provide additional margin during actual power production as specified in Reference
- 14. The pressure-temperature limits for WCAP*IS827 30 core operation (except for low power physics tests) arc that the re.'.lctor vessel must be at a temperature equal to or higher than the minimum temperature required for the inscrvice hydrostatic test. and at least 40°F higher the minimum pcnnissible temperature in the corresponding pressure-temperature curve for hcatup and cooldown calculated as described in Section 3.0 of this report. for the hcatup and coo1down curves without margins for instrumentation errors, the minimum temperatures for the in service hydrostatic 1e:tk tests for the H.B. Robinson Unit 2 reactor vessel at 30, 35, 40, 45 and 50 EFPY are 214°F, 216°F, 2 l 8°F, 2 J 9°F and 221°F, respectively.
The vertical line drawn from these points on the tcmperaturc curve, intersecting a curve 40°f higher than the pressure-temperature limit curve, constitutes the limit for core operation for the rC3ctor vessel. Figures 1 through I 0 define all of the above limits for ensuring prevention of nonductilc fuilure for the H.B. Robinson Unit 2 reactor vessel for various EFPYs. The data points used for the he.1tup and cooldown pressure-temperature limit curves shoY.n in Figures I through 10 arc presented in Tables 19 through 28. The balded values arc those limited by the girth weld using the "Circ-FJaw" Methodology.
The non-bolded values arc those limited by the Upper shell Plate using the standard "Axial-Flaw" Methodology from the 1996 version of the ASME Code Section XI, Appendix G WCAP-15827 31 MATERIAL PROPERTY BASIS LIMITING MATERIAL:
