NEDO-33785 Revision 0 1.0 Purpose The purpose of the Enrico Fermi Power Plant 2 (Fermi 2) Pressure and Temperature Limits Report (PTLR) is to present operating limits relating to:

1. Reactor coolant system (RCS) Pressure versus temperature limits during heatup, cooldown and hydrostatic/class 1 leak testing;
2. RCS heatup and cooldown rates;
3. Reactor pressure vessel (RPV) to RCS coolant AT requirements during Recirculation Pump startups;
4. RPV bottom head coolant temperature to RPV coolant temperature AT requirements during recirculation pump startups;
5. RPV head flange bolt-up temperature limits.

This report has been prepared in accordance with the requirements of Technical Specification (TS) 5.6.8, "Reactor Coolant System (RCS) PRESSURE AND TEMPERATURE LIMITS REPORT (PTLR)".

2.0 Applicability This report is applicable to the Fermi 2 RPV for up to 24 and 32 Effective Full Power Years (EFPY).

The following TS is affected by the information contained in this report:

TS 3.4.10 RCS Pressure and Temperature (P/T) Limits 3.0 Methodology The limits in this report were derived from the Nuclear Regulatory Commission (NRC)-approved methods listed in TS 5.6.8, using the specific revisions listed below:

1. The neutron fluence was calculated per Licensing Topical Report, General Electric Methodology for Reactor Pressure Vessel Fast Neutron Flux Evaluation, NEDC-32983P-A, Revision 2, January 2006, approved in Reference 6.1.
2. The pressure and temperature limits were calculated per GE Hitachi Nuclear Energy Methodologyfor Development of Reactor Pressure Vessel Pressure-TemperatureCurves, NEDC-33178P-A, Revision 1, June 2009, approved in Reference 6.2.
3. This revision of the pressure and temperature limits is to incorporate the following changes:
  • Initial issuance of the PTLR
  • Application of GEH licensing topical report (LTR) for pressure-temperature (P-T) curves
  • Thermal power optimization (TPO) at 3486 MWt 1

NEDO-33785 Revision 0

. The water level instrumentation (WLI) nozzle that occurs in the beltline region was fabricated from carbon steel and has been considered in the adjusted reference temperature (ART) evaluation. The fluence at this location is based on a less conservative power history that excludes EPU and considers TPO after RFO16.

The fluence used considers operation at 3293 MWt for 3.228 EFPY, 3430 MWt for 16.35 EFPY, and 3486 MWt (TPO) for 10.59 EFPY.

3.1 Chemistry The N16 WLI nozzle is defined as being within the beltline region, and is evaluated for ART.

Insufficient information was located to determine the copper and nickel content for these SA508 Class 1 forging materials. All available boiling water reactor (BWR) fleet SA508 Class 1 forging information was reviewed; fourteen (14) copper and thirty-five (35) nickel data points were obtained. The copper and nickel content was determined using the Mean + 1 , resulting in 0.272 %Cu and 0.214 %Ni.

3.2 Initial Reference Temperature of Nil Ductility Transition (RTNDT)

The N16 WLI nozzle is evaluated for ART. The Combustion Engineering (CE) purchase specification for this material demonstrates a required test temperature of 10°F, consistent with the N16 certified material test reports (CMTR). However, insufficient information is available to determine the initial RTNDT. NRC MTEB 5-2, paragraph B.1.1(4) defines the method for determining initial RTNDT where limited Charpy V-Notch tests were performed at a single temperature, as is the case for the N16 material. Testing for one N16 material was performed at 10F, with a minimum results of 30 ft-lbs and where the maximum results is less than 45 ft-lbs.

Therefore, MTEB 5-2 states that the RTNDT may be calculated as 20'F above the test temperature; hence, the initial RTNDT is determined to be 30 0 F. Testing for the second N16 material was performed at 10'F, but dropweight was not reported. The dropweight was considered to be 30'F, consistent with MTEB 5-2 guidance. Therefore, the initial RTNDT for this heat is the greater of the dropweight and TSoT - 60'F. The resulting initial RTNDT for this material is 30'F.

3.3 Adjusted Reference Temperature The ART values for 24 and 32 EFPY included in Appendix B are developed considering the latest BWR Vessel and Internals Project (BWRVIP) integrated surveillance program (ISP) published surveillance data available that is representative of the applicable materials in the Fermi 2 RPV (Reference 6.3). The surveillance data used in the Fermi 2 ART calculations is not obtained from actual Fermi 2 RPV test specimens. The ISP plate materials did not have the limiting ART. The ISP weld material has the limiting ART; this value is considered in the development of the P-T curves because the ISP material is the identical heat to the material in the Fermi 2 RPV.

3.4 Surveillance Program As discussed in Appendix A, Fermi 2 participates in the ISP. Two of the surveillance capsules, installed at plant startup, remain in the vessel, while the third capsule was removed at 2

NEDO-33785 Revision 0 approximately 8 EFPY, but was not tested. As Fermi 2 is not a host plant, the three (3) surveillance capsules have an ISP status designation of deferred (standby) per Reference 6.4.

Should actual surveillance capsules be withdrawn and tested from the Fermi 2 RPV (e.g., status change to be an ISP host plant under the BWRVIP ISP), compliance with 10 CFR 50 Appendix H requirements on reporting test results and evaluations on the effects to plant operations parameters (e.g., P-T limits, hydrostatic and leak test conditions) will be in accordance with Section 3 of Reference 6.3.

3.5 Beltline Weld Flaw Indications Three (3) flaw indications have been evaluated for the Fermi 2 vessel, occurring in Shell Ring #2, in weld 15-308 (axial weld). Flaw #124 requirements bound those of Flaw #127 and Flaw #128.

A fracture mechanics evaluation was conducted using techniques consistent with the philosophy of Section XI of the ASME Code. The indication, Flaw #124, was modeled with length equal to 4.24 inches (along the weld thickness direction) and width equal to 2 inches. The long end of the indication is located 0.7 inches from the inside diameter (ID) surface, which includes a clad thickness of 0.3125 inches.

At 32 EFPY, the hydrotest temperature is calculated to be 114.9°F at 1030 psig. For these conditions, the allowable value of K, is 34.0 ksi-inl/ 2 and does not bound the calculated value of K1, which is 35.7 ksi-in" 2 . Therefore, the beltline hydrotest P-T curve must be shifted to the right in order to increase the allowable value of KI, resulting in a calculated value of K, that is bounded by the allowable value of K1. For the 32 EFPY curve, an adjustment of 5°F was applied such that Curve A requires a temperature of 119.9°F at 1030 psig. Similarly, an adjustment of 13'F was applied for 24 EFPY.

For the limiting leak test condition at 32 EFPY, the highest calculated value of applied stress intensity factor was 35.7 ksi-in1/ 2 and the allowable value of KI was calculated to be 35.9 ksi-in" 2 . Because the calculated value of K, is less than the allowable value of K1, the indication is not expected to become a surface indication during future operation. The indication is acceptable in the as-is condition for operation up to 32 EFPY, including TPO/ measurement uncertainty recovery (MUR).

3.6 Future Changes Changes to the curves, limits, or parameters within this PTLR, based upon new irradiation fluence data of the RPV, or other plant design assumptions in the updated final safety analysis report (UFSAR), can be made pursuant to 10 CFR 50.59, provided the above methodologies are utilized. The revised PTLR shall be submitted to the NRC upon issuance.

4.0 Operating Limits The pressure-temperature (P-T) curves provided in this report represent steam dome pressure versus minimum vessel metal temperature and incorporate the appropriate non-beltline limits and irradiation embrittlement effects in the beltline region.

3

NEDO-33785 Revision 0 The operating limits for pressure and temperature are required for three categories of operation:

(a) hydrostatic pressure tests and leak tests, referred to as Curve A; (b) non-nuclear heatup/cooldown (core not critical), referred to as Curve B; and (c) core critical operation, referred to as Curve C.

Complete P-T curves were developed for 24 and 32 EFPY. The P-T curves are provided in Figures 1 through 6, and a tabulation of the curves is included in Table 1 (24 EFPY) and Table 2 (32 EFPY).

Other temperature limits applicable to the RPV and controlled by the TS are:

Heatup and cooldown rate limit during Hydrostatic and Class 1 Leak Testing:

< 20 °F/hour.

  • Normal operating heatup and cooldown rate limit: *100°F/hour.
  • RPV bottom head coolant temperature to RPV coolant temperature AT limit during Recirculation Pump startup: <145°F.
  • Recirculation loop coolant temperature to RPV coolant temperature AT limit during Recirculation Pump startup: <50°F.
  • RPV flange and adjacent shell temperature limit: >72°F.

5.0 Discussion The procedures described in References 6.1 and 6.2 were used in the development of the P-T curves for Fermi 2.

The method for determining the initial reference temperature of nil-ductility transition (RTNDT) for all vessel materials is defined in Section 4.1.2 of Reference 6.2. Initial RTNDT values for all vessel materials considered are presented in tables in Appendix B of this report.

For Fermi 2, the limiting surveillance material, weld heat 13253/12008, was considered using Procedure 1 as defined in Appendix I of Reference 6.2. This procedure was used because the target vessel material and the surveillance material are identical heats.

For Fermi 2, there are four (4) thickness discontinuities in the vessel: (1) between the bottom head upper and lower torus, (2) between the bottom head torus and the support skirt attachment, (3) between the bottom head torus and Shell Ring #1, and (4) between Shell Ring #1 and Shell Ring #2. The P-T curves defined in Section 4.3 of Reference 6.2 are based upon an RTNDT of 30'F for the bottom head Curves A and C, 44.6°F for the bottom head Curve B, and 25°F for the upper vessel. The 24 EFPY beltline curves are based on an ART of 75°F, and the 32 EFPY beltline curves are based on an ART of 82°F. Curves based on these temperatures bound the requirements due to the flaws discussed in Section 3.5, and the beltline thickness discontinuities.

The ART of the limiting beltline material is used to adjust the beltline P-T curves to account for irradiation effects. Regulatory Guide (RG) 1.99, Revision 2, provides the methods for determining the ART. The RG 1.99 methods for determining the limiting material and adjusting the P-T curves using ART are discussed in this section.

4

NEDO-33785 Revision 0 The vessel beltline copper and nickel values, with the exception of the N16 WLI nozzle, were obtained from plant-specific vessel purchase order records, CMTRs. The N16 nozzle is fabricated from SA508 Class 1 material; there is insufficient plant-specific chemistry information for these nozzles. Therefore, chemistry values using BWR fleet data and Mean + IC have been considered. The copper (Cu) and nickel (Ni) values were used with Tables 1 and 2 of RG 1.99, to determine a chemistry factor (CF) per paragraph 1.1 of RG 1.99 for welds and plates, respectively. ART values for 24 and 32 EFPY are presented in Appendix B. The ART tables also include plant-specific materials considering best estimate chemistry values obtained from Reference 6.3.

The P-T curves for the non-beltline region were conservatively developed for a BWR product line 6 (BWR/6) with nominal ID of 251 inches. The analysis is considered appropriate for Fermi 2 because the plant-specific geometric values are bounded by the generic analysis for the large BWR/6. The generic value was adapted to the conditions at Fermi 2 using plant-specific RTNDT values for the reactor pressure vessel.

The peak RPV ID fluence used in the P-T curve evaluation for Fermi 2 at 24 EFPY is 7.26e17 n/cm 2 and at 32 EFPY is 9.68e17 n/cm 2 . These values were calculated using methods that comply with the guidelines of RG 1.190, (as discussed in Reference 6.1). This fluence applies to the lower-intermediate shell plates and longitudinal welds. The fluence is adjusted for the lower plates, associated longitudinal welds, and the girth weld based upon the axial fluence distribution calculated as part of the fluence evaluation; hence, the peak ID surface fluence for these components is 4.67e17 n/cm 2 for 24 EFPY and 6.23e17 n/cm 2 for 32 EFPY. Similarly, the fluence is adjusted for the N16 nozzle based upon the axial fluence distribution; hence the peak ID surface fluence used for this component is 1.24e17 n/cm 2 for 24 EFPY and 1.65e17 n/cm 2 for 32 EFPY. It is also noted that the fluence used for the N16 nozzle is based on a less conservative power history as noted in Section 3.0.

The P-T curves for the heatup and cooldown operating conditions at a given EFPY apply for both the 1/4T and 3/4T locations. When combining pressure and thermal stresses, it is usually necessary to evaluate stresses at the 1/4T location (inside surface flaw) and the 3/4T location (outside surface flaw). This is because the thermal gradient tensile stress of interest is in the inner wall during cooldown and the outer wall during heatup. However, as a conservative simplification, the thermal gradient stress at the 1/4T location is assumed to be tensile for both heatup and cooldown. This results in the approach of applying the maximum tensile stress at the 1/4T location. This approach is conservative because irradiation effects cause the allowable toughness, KIr, at 1/4T to be less than that at 3/4T for a given metal temperature. This approach causes no operational difficulties, because the BWR is at steam saturation conditions during normal operation, well above the heatup/cooldown curve limits.

For the core not critical curve (Curve B) and the core critical curve (Curve C), the P-T curves specify a coolant heatup and cooldown temperature rate of < 100°Fihr for which the curves are applicable. However, the core not critical and the core critical curves were also developed to bound transients defined on the RPV thermal cycle diagram and the nozzle thermal cycle diagrams. For the hydrostatic pressure and leak test curve (Curve A), a coolant heatup and 5

NEDO-33785 Revision 0 cooldown temperature rate of < 20°F/hr must be maintained. The P-T limits and corresponding heatup/cooldown rates of either Curve A or B may be applied while achieving or recovering from test conditions. Curve A applies during pressure testing and when the limits of Curve B cannot be maintained.

For Fermi 2, weld heat 13253/12008 is the limiting material for the beltline region for 24 and 32 EFPY. The initial RTNDT for weld heat 13253/12008 material is -44'F. The generic pressure test P-T curve is applied to the Fermi 2 beltline curve by shifting the P vs. (T - RTNDT) values to reflect the ART value of 75°F for 24 EFPY and 82°F for 32 EFPY. Using the fluence discussed above, the P-T curves are beltline limited for Curves A, B, or C, for 24 or 32 EFPY. For 24 EFPY, Curve A is beltline limited above 900 psig; Curve B and Curve C are beltline limited above 730 psig. For 32 EFPY, Curve A is beltline limited above 840 psig; Curve B and Curve C are beltline limited above 600 psig.

In order to ensure that the limiting vessel discontinuity has been considered in the development of the P-T curves, the methods in Sections 4.3.2.1 and 4.3.2.2 of Reference 6.2 for the non-beltline and beltline regions, respectively, are applied.

NEDO-33785 Revision 0 Appendix A Reactor Vessel Material Surveillance Program In accordance with 10 CFR 50, Appendix H, Reactor Vessel Material Surveillance Program Requirements, the first surveillance capsule was removed from the Fermi 2 reactor vessel after Cycle 7, during refueling outage (RFO) 7 in April 2000. This capsule was placed in the Spent Fuel Pool and has not been tested. The surveillance capsule contains flux wires for neutron fluence measurement, Charpy V-Notch impact test specimens and uniaxial tensile test specimens fabricated using materials from the vessel materials within the core beltline region.

As described in the Fermi 2 Updated Final Safety Analysis Report (UFSAR) Section 4.2.6, Inspection and Testing, the BWRVIP ISP will determine the removal schedule for the remaining Fermi 2 surveillance capsules. The Fermi 2 material surveillance program is administered in accordance with the BWRVIP ISP. The ISP combines the US BWR surveillance programs into a single integrated program. This program uses similar heats of materials in the surveillance programs of BWRs to represent the limiting materials in other vessels. It also adds data from the BWR Supplemental Surveillance Program (SSP). Per the BWRVIP ISP, Fermi 2 is not a host plant; all surveillance capsules are classified as "Deferred".

(2) Alloy 600 components do not require fracture toughness evaluation.

(3) Dropweight data was not available; therefore NRC MTEB 5-2 was applied for the determination of dropweight.

Notes: Minimum Charpy values are provided for all materials.

The Replacement Instrument nozzle material data was reviewed; it was found that the previously reported value of 40'F was unnecessarily conservative, and has been reduced to a maximum of 307F.
