DESCRIPTION This letter is a request to amend Operating License NPF-57 for the Hope Creek Generating Station (HCGS). The proposed amendment would revise the reactor pressure vessel (RPV) pressure-temperature (P-T) limits in Technical Specification (TS) Figures 3.4.6.1-1, 3.4.6.1-2 and 3.4.6.1-.3 and extend the validity of the limits to 32 effective full power years (EFPY). The updated P-T limits are based on an RPV neutron fluence calculated using an NRC staff-accepted neutron fluence methodology for boiling water reactors. The revised P-T limit curves satisfy the requirements of Appendix G to 1 OCFR Part 50.

2.

PROPOSED CHANGE The marked up pages for the proposed changes to the Technical Specifications are included in Attachment 2 of this submittal.

The current TS Figures 3.4.6.1-1, 3.4.6.1-2 and 3.4.6.1-3, which establish P-T limitations for the reactor coolant system, will be replaced by the figures in. The updated P-T curves are valid through the end of the 40-year operating license and are based on a re-calculation of neutron fluence using an NRC staff-accepted neutron fluence methodology for boiling water reactors (BWRs) which is consistent with the requirements of Regulatory Guide 1.190, "Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence," (Reference 1).

Changes to the TS Bases would also be made to reflect the changes to the P-T limits. The marked up Bases pages are also included in Attachment 2 of this submittal.

PSEG plans to implement the proposed change to support the next refueling outage (i.e., Fall 2004) and subsequent restart. Because the current set of P-T curves expire at the end of the current operating cycle (defined as the end of the next refueling outage), a license amendment is required before the end of the refueling outage. The next refueling outage is currently scheduled to begin in October 2004.

3.

BACKGROUND 10 CFR 50.60 requires that light-water nuclear power reactors meet the fracture toughness requirements for the reactor coolant pressure boundary set forth in Appendix G to 10 CFR 50. Appendix G is the regulatory basis for P-T curves for light water reactors. Appendix G specifies fracture toughness requirements for ferritic materials of pressure-retaining components of the reactor coolant pressure boundary to provide adequate margins of safety during any condition of LR-N04-0136 LCR H03-09 normal operation, including anticipated operational occurrences and system hydrostatic tests, to which the pressure boundary may be subjected over its service lifetime. Appendix G also requires that the reference temperature and Charpy upper-shelf energy for reactor vessel beltline materials account for the embrittlement caused by neutron fluence over the life of the vessel.

RG 1.190 describes methods and assumptions acceptable to the NRC staff for determining the pressure vessel neutron fluence. RG 1.99, 'Radiation Embrittlement of Reactor Vessel Materials" (Reference 2) describes general procedures acceptable to the NRC staff for calculating the effects of neutron radiation embrittlement of the low-alloy steels currently used for light-water-cooled reactor vessels.

The P-T curves approved in Amendment No. 131 (Reference 3) were developed using the methodology specified in American Society of Mechanical Engineers (ASME) Code Cases N-588 and N-640, as well as the 1989 ASME Code, Section Xl, Appendix G, and 10 CFR Part 50, Appendix G. Adjusted reference temperatures at the nil ductility transition values were developed for the reactor pressure vessel materials in accordance with RG 1.99, Revision 2. In the Safety Evaluation for Amendment No. 131 the NRC staff concluded that, while there was ample margin to allow use of the revised P-T curves through Cycle 11, the revised P-T curves could not be approved for the 32 EFPY for which they were intended until the fluence values were recalculated using the guidance of RG 1.190.

In Amendment 139 (Reference 4), the NRC staff approved use of the existing P-T limit curves for one additional cycle (through the end of Cycle 12). The estimated fluence at the end of Cycle 12 is less than half of the calculated fluence for 32 EFPY upon which the current P-T limits are based.

10 CFR 50 Appendix G requires reactor vessel beltline materials to be tested in accordance with the surveillance program requirements of 10 CFR 50 Appendix H. In References 5 and 6, PSEG requested a change the HCGS reactor vessel material surveillance program to incorporate the Boiling Water Reactor Vessel and Internals Project (BWRVIP) Integrated Surveillance Program (ISP) into the HCGS licensing basis. The updated fluence calculations described in Section 4 of this Attachment meet the condition for use of compatible neutron fluence methodologies acceptable to the NRC staff.

4.

TECHNICAL ANALYSIS Revised pressure-temperature (P-T) curves were developed for pressure test, core not critical, and core critical conditions. A report describing the inputs, methodology and results for the revised curves is provided in Attachment 3. The LR-N04-0136 LCR H03-09 revised curves are applicable for 32 effective full power years (EFPY). Curves applicable for 48 EFPY are included in the report for information only.

The curves were developed using the methodology specified in American Society of Mechanical Engineers (ASME) Code Cases N-588 and N-640 as well as the 1989 ASME Code, Section Xl, Appendix G, and 10 CFR Part 50, Appendix G.

ASME Code Case N-640 permits application of the lower bound static initiation fracture toughness value equation (Kic equation) as the basis for establishing the P-T curves in lieu of the lower bound crack arrest fracture toughness value equation (i.e., the KiA equation). The KIA equation is based on conditions needed to arrest a dynamically propagating crack and is the method invoked by Appendix G to Section Xl of the 1989 ASME Code. Use of the Kic equation in determining the lower bound fracture toughness in the development of the P-T operating

-limits curve is more technically correct than the use of the KIA equation because the rate of loading during a heatup or cooldown is slow and is more representative of a static condition than a dynamic condition. RG 1.147, "Inservice Inspection Code Case Acceptability, ASME Section Xl, Division 1,"

Revision 13, January 2004 (Reference 7) states that Code Case N-640 is acceptable to the NRC for application in licensees' Section Xl inservice inspection programs.

ASME Code Case N-588 permits postulation of a circumferentially oriented flaw (in lieu of an axially-oriented flaw) for the evaluation of the circumferential welds in RPV P-T limit curves. RG 1.147 states that Code Case N-588 is acceptable to the NRC for application in licensees' Section Xl inservice inspection programs.

Neutron Fluence Calculations The neutron fluence calculations were updated using the NRC-approved General Electric Nuclear Energy (GENE) methodology documented in GENE's Licensing Topical Report NEDC-32983P-A (Reference 8). The NRC-accepted proprietary methodology is fully described in NEDC-32983P-A and is not repeated herein. In general, GENE's methodology is consistent with the guidance in RG 1.190 for neutron flux calculations and is based on a two-dimensional discrete ordinates code.

The fluence is based upon operation for 32 EFPY, with 12 EFPY at 3293 MWt, the original licensed thermal power, 3 EFPY at 3339 MWt, the current licensed thermal power, and the remaining 17 EFPY at 3952 MWt which bounds operation at the current licensed thermal power through the end of the 40-year operating license. The updated fluence evaluation (at 3952 MWt) was performed using the GENE methodology. The calculated RPV flux value for 3293 MWt is based on the neutron transport calculation described in Reference 9 in which the jet pumps were not modeled. Results from the updated fluence evaluation demonstrated that the neutron transport calculation in Reference 9 provided sufficient Attachment I LR-N04-0136 LCR H03-09 conservatism to permit its use for operation at 3293 MWt. The peak flux for 3339 MWt includes a 1.4% uprate from 3293 MWt.

The peak calculated RPV inside surface fluxes are provided below:

Power Level (MWt)

Flux (n/cm'-s) 3293 9.3x104 3952 1.22x10" The calculated fast neutron fluences at the end of plant life (32 EFPY) are provided below:

Peak Surface 1.1x10' Peak 1/4 T 7.6x101' Limiting Beltline Material Peak Surface 5.3x101" Limiting Beltline Material Peak 1/4 T 3.7x1 0" Regulatory Guide 1.99 and Adiusted Reference Temperature Adjusted reference temperature (ARTNDT) values were recalculated in accordance with Regulatory Guide 1.99, Revision 2 based on the new calculated fluence values.

Upper shelf energy (USE) calculations were performed and confirmed that all USE values are greater than 50 ft-lb throughout RPV life as required by 10 CFR 50 Appendix G. For the limiting USE material, the USE at 32 EFPY decreased from 61 to 60 ft-lb.

Pressure-Temperature Curve Evaluation Three regions of the reactor pressure vessel (RPV) were evaluated to develop the revised P-T curves: (1) the beltline region, (2) the bottom head region, and (3) the feedwater nozzle/upper vessel region. These regions bound all other regions with respect to brittle fracture.

The methodology used to generate the P-T curves in this submittal is similar to the methodology used to generate the curves approved in HC TS Amendment No. 131. In this update, however, the estimate of the RPV neutron fluence was based on a new fluence methodology that follows the guidance of Regulatory Guide 1.190.

Non-Beltline Regions Non-beltline regions are defined as the vessel locations that are remote from the active fuel and where the end-of-life (EOL) neutron fluence is not sufficient (i.e., <

LR-N04-0136 LCR H03-09 1017 n/cm2) to cause any significant embrifflement. Non-beltline components include nozzles, closure flanges, some shell plates, the top and bottom head plates, and the control rod drive penetrations.

For the feedwater nozzles, an updated ASME Code stress and fatigue analysis demonstrated acceptable fatigue life through the end of the 40-year operating license, including the effects of operation at 3952 MWt which bounds operation at the current licensed thermal power. Calculated stresses from the updated analysis were used to develop pressure-temperature limits for the upper vessel.

The methodologies used to develop the proposed P-T limit curves satisfy the requirements of the regulations (as modified by application of ASME Code Cases N-588 and N-640). The revised P-T curves and outputs from the Integrated Surveillance Program (which when approved by NRC for use at HCGS, will be used, as appropriate, for future adjustments to P-T limits) ensure that adequate RPV safety margins against non-ductile failure will continue to be maintained during normal operations, anticipated operational occurrences, and hydrostatic testing. Together, these measures ensure that the integrity of the reactor coolant system will be maintained for the life of the plant.

5.

REGULATORY SAFETY ANALYSIS 5.1 No Significant Hazards Consideration PSEG Nuclear (PSEG) has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, 'Issuance of amendment" as discussed below:

1.

Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response

No.

The revised curves are based on uprated fluence projections and are applicable for the service period up to 32 effective full power years (EFPY). There are no changes being made to the reactor coolant system (RCS) pressure boundary or to RCS material, design or construction standards. The proposed heatup and cooldown curves define limits that continue to ensure the prevention of nonductile failure of the RCS pressure boundary. The design-basis events that were evaluated have not changed. The modification of the heatup and cooldown curves does not alter any assumptions previously made in the radiological consequence evaluations since the integrity of the RCS pressure boundary is LR-N04-0136 LCR H03-09 unaffected. Therefore, the proposed changes will not significantly increase the probability or consequences of an accident previously evaluated.

2.

Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response

No.

Revisions to the heatup and cooldown curves do not involve any new components or plant procedures. The proposed changes do not create any new single failure or cause any systems, structures or components to be operated beyond their design bases.

Therefore, the proposed license amendment does 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 a margin of safety?

Response

No.

The proposed figures define the limits for ensuring prevention of nonductile failure for the reactor coolant system based on the methods described in 1989 ASME Code Section Xl Appendix G, 10CFR 50 Appendix G, and ASME Code Cases N-640 and N-588.

The effect of the change is to permit plant operation within different pressure-temperature limits, but still with adequate margin to assure the integrity of the reactor coolant system pressure boundary. Therefore, the proposed change does not involve a significant reduction in a margin of safety.

Based on the above, PSEG concludes that the proposed changes present no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and accordingly, a finding of "no significant hazards consideration" is justified.

5.2 Applicable Regulatory RequirementslCriteria 10 CFR 50.60 requires that light-water nuclear power reactors meet the fracture toughness requirements for the reactor coolant pressure boundary set forth in Appendix G to 10 CFR 50. Appendix G is the regulatory basis for P-T curves for light water reactors. Appendix G specifies fracture toughness requirements for ferritic materials of pressure-retaining components of the reactor coolant pressure boundary to provide adequate margins of safety during any condition of normal operation, LR-N04-0136 LCR H03-09 including anticipated operational occurrences and system hydrostatic tests, to which the pressure boundary may be subjected over its service lifetime. Appendix G also requires that the reference temperature and Charpy upper-shelf energy for reactor vessel beltline materials account for the embrittlement caused by neutron fluence over the life of the vessel.

Regulatory Guide (RG) 1.190, uCalculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence," dated March 2001 contains the U.S. Nuclear Regulatory Commission (NRC) staffs guidance on how to determine neutron fluence. RG 1.99, 'Radiation Embrittlement of Reactor Vessel Materials" (Reference 2) describes general procedures acceptable to the NRC staff for calculating the effects of neutron radiation embrittlement of the low-alloy steels currently used for light-water-cooled reactor vessels.

In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

6.

ENVIRONMENTAL CONSIDERATION PSEG has determined the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or a surveillance requirement. The proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), an environmental assessment of the proposed change is not required.

REACTOR COOLANT SYSTEM BASES 3/4.4.6 PRESSURE/TEMPERATURE LIMITS All components in the reactor coolant system are designed to withstand the effects of cyclic loads due to system temperature and pressure changes.

These cyclic loads are introduced by normal'load transients, reactor trips, and startup and shutdown operations. The various categories of load cycles used for design purposes are provided in Section (3.9) of the UFSAR.

During startup and shutdown, the rates of temperature and pressure changes are limited so that the maximum specified heatup and cooldown rates are consistent with the design assumptions and satisfy the stress limits for cyclic operation. Specifically the average rate of change of reactor coolant temperature during normal heatup and cooldown shall not exceed 100°F during any 1-hour period.

The operating limit curves of Figures 3.4.6.1-1, 3.4.6.1-2, and 3.4.6.1-3 are derived from the fracture toughness requirements of 10 CFR 50 Appendix G and ASME Code Section XI, Appendix G and ASME Code Cases N-588 and N-640.. The curves are based on the RTmm and stress intensity factor information for the reactor vessel components.

Fracture toughness limits and the basis for compliance are more fully discussed in SAR Chapter 5, Paragraph 5.3.1.5, "Fracture Toughness."

The reactor vessel materials have been tested to determine their initial RTNOT.

The results of some of these tests are shown in Table B 3/4.4.6-1. Reactor operation and resultant fast neutron, E greater than 1 MeV, irradiation will cause an increase in the RT=,.

Therefore, an adjusted reference temperature, based upon the fluence, nickel content and copper content of the material in question, can be predicted using Bases Figure B 3/4.4.6-1 and the recommendations of Regulatory Guide 1.99, Rev. 2, "Radiation Embrittlement of Reactor Vessel Material".

The pressure/

temperature limit curves, Figures 3.4.6.1-1, 3.4.6.1-2, and 3.4.6.1-3, includes an assumed shift in RTmT for the end of life fluence.

The actual shift in RTIS of the vessel material will be established periodically during operation by removing and evaluating, irradiated flux wires installed near the inside wall of the reactor vessel in the core area.

Since the neutron spectra at the flux wires and vessel inside radius are essentially identical, the irradiated flux wires can be used with confidence in predicting reactor vessel material transition temperature shift. The operating limit curves of Figures 3.4.6.1-1, 3.4.6.1-2, and 3.4.6.1-3 shall be adjusted, as required, on the basis of the flux wire data and recommendations-of Regulatory Guide 1.99, Rev. 2.

Revised Pressure-Temperature (P-T) Curves for Hope Creek

Reference:

PSEG Purchase Order No. 4500204466 dated 6/27/03

Dear Randy:

The attachment to this letter documents the revised set of pressure-temperature (P-T) curves developed for the Hope Creek Generating Station, in accordance with SI's Quality Assurance Program. This work was performed in accordance with the referenced contract, and includes a full set of updated P-T curves (i.e., pressure test, core not critical, and core critical conditions) for 32 and 48 effective full power years (EFPY). The curves were developed in accordance with 1989 ASME Code Section XI Appendix G, U.S. IOCFR 50 Appendix G, and ASME Code Cases N-588 and N-640.

The inputs, methodology, and results for this effort are summarized in the attachment. The calculations for this work (PSEG-IOQ-301 and -302) are also attached.

Please don't hesitate to call me if you have any questions.

  • ATTACHMENT Revised P-T Curves for Hope Creck 1.0 Introduction This attachment documents the revised set of pressure-temperature (P-T) curves developed for the Hope Creelk Generating Station. This work includes a full set of updated P-T curves (i.e.,

pressure test, core not critical, and core critical conditions) for 32 and 48 effective full power years (EFPY). The curves were developed using the methodology specified in ASME Code Cases N-588 [2] and N-640 [3], as well as 1989 ASME Code Section XI Appendix G [4],

IOCFR50 Appendix G [5], and WRC-175 [6]. The improvement realized from the Code Case methodology is as much as 60'F, and is primarily obtained from using the critical fracture toughness, KIc, in accordance with Code Case N-640. This revision of the previously issued report incorporates revised RTNDT values [17], effects of a potential Extended Power Uprate (EPU) of 20% increase [18], and an updated feedwater nozzle thermal stress and fatigue evaluation [16, 19] (which supersedes the work in Reference 20). The new fluence estimates for projected EPU conditions [17] only affect beltline components which are exposed to high fluence, and therefore [1] is still the controlling document for the initial RTNDT values for non-beltline components.

2.0 RTNDT Values Adjusted reference temperature (ARTNDT) values were developed for the Hope Creek reactor pressure vessel (RPV) materials in accordance with NRC Regulatory Guide 1.99, Revision 2

[13] based on the revised fluence data contained in Reference [1 7]. An EXCEL spreadsheet was set up to perform the RTNDT calculations for the different EFPY levels required for this work, and is shown in Table 1 for 32 EFPY and Table 2 for 48 EFPY. The ARTNDT values calculated in Table 1 match the values from Reference [17], with only minor variation due to differences in the number of significant figures used in the calculations. To calculate the 48 EFPY ARTNDT values shown in Table 2, the fluence values from [17] were conservatively multiplied by a factor of 1.5 corresponding to a linear increase with time. The most limiting beltline material is the Intermediate Plate, Heat No. 5K3025/1.

The supporting calculations for the curves are contained in References [7] and [8]. There are three regions of the reactor pressure vessel (RPV) that are evaluated: (1) the beltline region, (2) the Attachment to SIR-00-136, Rev. 1 V

Structural IntegrityAssociates, Inc.

bottom head region, and (3) the feedwater nozzle/upper vessel region. These regions bound all other regions with respect to brittle fracture.

The approach used for the beltline and bottom head (all curves), and upper vessel (Curve A only) includes the following steps:

a.

Assume a fluid temperature, T. The temperature of the metal at the assumed flaw tip, TI,4t (i.e., 1/4t into the vessel wall) is conservatively assumed equal to fluid temperature. The assumed temperature also must account for an instrument uncertainty of 90F [14].

b.

Calculate the allowable stress intensity factor, K1C, based on T,/4t using the relationship from Code Case N-640 [3], as follows:

KIC = 20.734 e0.02(TI4I ARTN

+ 33.2 (eqn. from Ref. [9])

where: T1,4t

= metal temperature at assumed flaw tip (fF)

ARTNDT = adjusted reference temperature for location under consideration and desired EFPY (fF)

Kic

= allowable stress intensity factor (ksiNinch)

c.

Calculate the thermal stress intensity factor, Krr from Code Case N-588 [2] for the beltline and bottom head regions, or from finite element results for the feedwater nozzle/upper vessel region.

d.

Calculate the allowable pressure stress intensity factor, KIP, using the following relationship:

KIp (KIc-Krr)/SF where:

Klp = allowable pressure stress intensity factor (ksWinch)

SF

= safety factor

=

1.5 for pressure test conditions (Curve A)

= 2.0 for heatup/cooldown conditions (Curves B and C)

e.

Compute the allowable pressure, P, from the allowable pressure stress intensity factor, K1p.

f.

Subtract any applicable adjustments for pressure from P. The beltline and bottom head include a pressure adjustment of 20.3 psig to account for the static pressure head of a full vessel. An instrument error of 20.5 psig was also assumed [15].

g.

Repeat steps (a) through (f) for other temperatures to generate a series of P-T points.

The approach used for the upper vessel (Curves B & C) includes the following steps:

Attachment to SIR-00-136, Rev. 1 StructuralIntegrityAssociates, Inc.

a.

Assume a fluid pressure, P. The assumed pressure includes an instrument uncertainty of 20.5 psig [15].

b.

Calculate the thermal stress intensity factor, Krr, based on finite element stresses.

The feedwater nozzle stresses were obtained from the finite element analysis results contained in Reference [16].

The highest linearized (membrane and membrane + bending) thermal stresses for all of the design basis transients were selected to encompass all expected operating conditions.

Calculate the allowable stress intensity factor, Kic, using the following relationship for a heatup/cooldown P-T curve:

1c-K 2.0 thus:

KIC = 2.0Kgp + KrT

e.

Calculate the temperature, T, using the relationship from Code Case N-640 [3],

as follows:

Kic = 20.734 e[0 02(TJ14 1

The curve was generated by scaling the stresses used to determine the pressure and thermal stress intensity factors. The primary stresses were scaled based on pressure, while the secondary stresses were scaled based on temperature difference.

g.

Repeat steps (a) through (f) for other pressures to generate a series of P-T points.

The following additional requirements were used to define the P-T curves. These limits are established in Reference [5]:

For Pressure Test Conditions (Curve A):

If the pressure is greater than 20% of the pre-service hydro test pressure (312.6 psig), the temperature must be greater than ARTNDT of the limiting flange material + 90'F.

If the pressure is less than or equal to 20% of the pre-service hydro test pressure, the minimum temperature is must be greater than or equal to the ARTNDT of the limiting flange material + 60'F. The instrument uncertainty of 90F was not Attachment to SIR-00-136, Rev. 1 V

applied since the 600F is an additional margin above that recommended in Reference [10], and has been a standard recommendation for the BWR industry for non-ductile failure protection.

Therefore, the 60'F is considered to adequately encompass instrument uncertainty.

For Core Not Critical Conditions (Curve B):

If the pressure is greater than 20% of the pre-service hydro test pressure (312.6 psig), the temperature must be greater than RTNDT of the limiting flange material

+ 1200F.

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 ARTNDT of the limiting flange material + 600F. The instrument uncertainty of 90F was not applied since the 600F is an additional margin above that recommended in Reference [10], and has been a standard recommendation for the BWR industry for non-ductile failure protection.

Therefore, the 60'F is considered to adequately encompass instrument uncertainty.

For Core Critical Conditions (Curve C):

Per the requirements of Table 1 of Reference [5], the core critical P-T limits must be 40'F above any Pressure Test or Core Not Critical curve limits. Core Not Critical conditions are more limiting than Pressure Test conditions, so Core Critical conditions are equal to Core Not Critical conditions plus 40 0F.

Another requirement of Table 1 of Reference [5] (or actually an allowance for the BWR), concerns minimum temperature for initial criticality in a startup.

Given that water level is normal, BWRs are allowed initial criticality at the closure flange region temperature (ARTNDT + 600F) if the pressure is below 20% of the pre-service hydro test pressure.

Also per Table 1 of Reference [5], at pressures above 20% of the pre-service hydro test pressure, the Core Critical curve temperature must be at least that required for the pressure test (Pressure Test Curve at 1,100 psig). As a result of this requirement, the Core Critical curve must have a step at a pressure equal to 20% of the pre-service hydro pressure to the temperature required by the Pressure Test curve at 1,100 psig, or Curve B + 40'F, whichever is greater.

After accounting for instrument uncertainties, the resulting pressure and temperature series constitutes the P-T curve. The P-T curve relates the minimum required fluid temperature to the reactor pressure.

4.0 P-T Curvcs Tabulated values for the P-T curves are shown in Tables 3 through 11. The resulting P-T curves are shown in Figures 1 through 5. Note that since the upper vessel (non-beltline) curve is limiting for core not critical conditions for both 32 and 48 EFPY, Curve C is identical for both EFPY levels (i.e., no fluence effects).
