1.0 INTRODUCTION
The purpose of this analysis is to determine the Florida Power Corporation Crystal River Unit 3 (CR3) reactor vessel adjusted reference temperature data for 32 effective full power years (32 EFPY). This information is to be used in the preparation of pressure-temperature operating limits curves applicable through 32 EFPY.
10
SUMMARY
OF RESULTS The adjusted reference temperature values applicable through 32 EFPY for the CR3 reactor vessel beltline materials are listed in Table 1. These values were calculated in accordance with the guidelines outlined in Regulatory Guide 1.99, Revision 2.' The controlling values of the adjusted reference temperature for the CR3 reactor vessel beltline material are 213.0 F at the %-thicknras (%T) wall location and 144.5 F at the
%-thickness (%T) wall location.
3.0 ASSUMPTIONS No major assumptions are containen in this report.
4.0 REACTOR VESSEL FLUENCE 4.1 Reactor Vessel inside Surface Fluence The extrapolated 32 EFPY inside surface fluences for the CR3 reactor vessel beltline materials are listed in Table 2.2 4.2 Attenuation Through Vessel Wall in accordance with Regulatory Guide 1.99, Revision 2, the neutron fluence at the %T and %T wall locations in the vessel, f (x 10 n/cm, E>1 2
MeV),is determined as follows:
/ = f,, (e*' )
(1) where fur (10'8 n/cm, E>1 MeV) is the calculated value of the neutron 2
fluence at the inner wetted surface of the vessel, and x (in inches) is the depth into the vessel wall measured from the vessel inner surface. The CR3 reactor vessel thickness is reported in BAW-1543, Revision 4 to be 8.44 inches. The 32 EFPY fluence values for the Cr 3 reactor vessel beltline materials at the %T and %T wall locations, a presented in Table 2.

5.1 Initial RTNor The initial RT or is the reference temperature for the unirradiated base N
metal vessel beltline material as defined in Paragr 111 of the ASME Boiler and Pressure Vessel Code.,aph NB-2331 of Section If measured values of initial RT or for the materialin question are not available, generic mean N
values for that class of material may be used if there are sufficient test results to establish a mean and standard deviation for the class.
The initial RTNor of weld wire heat 72105 is determined using an alternative method based on the material fracture toughness in the transition range. This rnethod is described in BAW-2202.5 Table 3 lists the initial RT or values for the CR3 reactor vessel beltline N

ARTuor is the mean value of the adjustment in reference temperature caused by irradiation and is calculated as follows:
ARTuor = (CF) *(ff)
(2) where:
= Chemistry Factor ff
= fluence factor 5.2.1 Chemistry Factor The chemistry factor (CF) is a function of the material's copper and nickel content. The CF is determined from Table 1 (for weld metals) and Table 2 (for base metals)in Regulatory Guide 1.99, Revision 2. Linear interpolation is permitted. When determining the CF, the " weight percent copper" and " weight percent nickel" are best estimate values for the material, which will normally be the mean of the measured values for the material.
The copper and nickel contents for the beltline base metal materials are reported in BAW-1820,7 and the copper and nickel contents for the beltline weld metals are reported in BAW-2121P.'
The copper content for the lower nozzle belt forging is unavailable, therefore the mean copper content is determined using data from other plants with similar materials. To compensate for heat PREPARER:

1.
Materials in the capsules should be those judged most likely to be controlling with regard to radiation embrittlement according to the recommendations of Regulatory Guide 1.99, Revision 2.
2.
Scatter in the plots of Charpy energy versus temperature for the irradiated and unirradiated conditions should be small enough to permit the determination of the 30 ft-Ib temperature unambiguously.
3.
When there are two or more sets of surveillance data from one reactor, the scatter of ARTuor values about a best-fit line drawn as described in Regulatory Guide 1.99, Revision 2, Position 2.1 normally should be less than 28'F for welds and 17'F for base metal. Even if the fluence range is large (two or more orders of magnitude), the scatter should not exceed twice those values.

The irradiation temperature of the Charpy specimens in the capsule

5.
The suNeillance data for the correlation monitor material in the capsule should fall within the scatter band of the data b&se for that material.

. Appendix B provides the evaluation of the Regulatory Guide 1.99, Revision 2, credibility criteria for the availaole surveillance data for CR3.
I When two or more credible surveillance data sets are available, these data may be used to determine the adjusted reference temperature of the reactor vessel beltline materials as follows:
First, if there is clear evidence that the copper or nickel content of the l
surveillance weld differs from that of the reactor vessel weld, the measured values of ART or should be adjusted by multiplying the values by the ratio of the N
chemistry factor for the reactor vessel weld to that for the surveillance weld.
. Second, using the ART or and its corresponding fluence, the chemistry factor N
may be calculated by multiplying each adjusted ART or by the corresponding N
fluence factor, summing the products, and dividing by the sum of the squares of j
the fluence factors:

The CR3 plant specific reactor vessel surveillance program (RVSP) provides data for predicting the reference temperature shift for the base metal plate heat number C4344-1. In addition, the Master Integrated Reactor Vessel Surveillance Program'(MIRVP) described in BAW-1543, Revision 4, provides surveillance data for weld metals SA-1769 and WF-70 on predicting the reference temperature shift.

TECHNOLOGIES FTl NON-PROPRIETARY 32-5000218-00 To verify that the adjusted reference temperature for each beltline material is a bounding value for the specific reactor vessel, plant specific information that could affect the level of embrittlement should be considered. This information includes, bu not limited to, the reactor vessel operating temperature and any related surveillance data that is available. The results of plant specific surveillance program data should be integrated into the adjusted reference temperature projection if the plant specific surveillance data has been deemed credible as judged by the criteria presented in l
Section 6.0 of this calculation. This Appendix provides the review of the available 1
surveillance data for CR3 against these credibility criteria.
i i
Criterion 1. Materials in the capsules should be those judged most likely to be controlling with regard to radiation embrittlement according to the recommendations of Regulatory Guide 1.99, Revision 2.
Surveillance data available include the following materials:
I 1
Base Metal Heat No. C4344-1 (CR3 plant-specific RVSP data) i Weld Wire Heat No. 71249 (MIRVP data)
Weld Wire Heat No. 72105 (MIRVP data)
All these heats of material lie within the reactor vessel beltline region of the CR3 reactor vessel as defined in 10 CFR 50, Appendix G.3' Therefore, these materials could be controlling with regard to radiation embrittlement.
i Criterion 2. Scatter in the plots of Charpy energy versus temperature for the irradiated and unfrradiated conditions should be small enough to i
permit the determination of the 30 ft-lb temperature unambiguously.
l The available Charpy V-notch data for these surveillance data permit the determination of the 30 ft-lb temperatures and are presented in their respective RVSP reports.
Criterion 3. When there are two or more sets of surveillance data from one reactor, the scatter of ARTuor values about a best-fit line drawn as l
described in Regulatory Guide 1.99, Revision 2, Position 2.1 normally should be less than 28 F for welds and 17 F for base metal. Even if the fluence range is large (two or more orders of magnitude), the scatter should not exceed twice those values.
The scatter of the measured ART or values for the available surveillance data are N
presented in Table B-1 for the bas'e metal and Table B-2 for the weld metals. The scatter of the measured ARTuor values about the best fit line drawn as described in PREPARER:

FRAMATOME TECHNOLOGIES FTl NON-PROPRIETARY 32-5000218 00 Regulatory Guide 1.99, Revision 2, Position 2.1 is greater than 17 F for the base and greater than 28 F for the weld metals.
Criterion 4. The irradiation temperature of the Charpy specimens in the capsule should match the vessel wall temperature at the cladding / base metal interface within 25'F.
The surveillance data for the base metal C4344-1, the Oconee Units 2 and 3 (OC2 and OC3) weld metal WF-209-1, and the B&WOG weld metal WF-70 were irradiated in the CR3 with a cold leg operating temperature of 556 F. The cold leg operating temperature for the Turkey Point Unit 3 (TP3) and the Turkey Point Unit 4 (TP4) surveillance weld data (SA-1101 and SA-1094 respectively) is 546*F and is within 25 F of the cold leg operating temperature for CR3. However, the cold leg operating temperature for the Zion Unit 1 (Z1) and the Zion Unit 2 (Z2) surveillance weld data l
'(WF-209-1) is 529 F and is not within 25 F of the cold leg operating temperature for CR3. Therefore, all the available MIRVP surveillance weld data for the welds SA-1769 and WF-70 with the exception of the Zion Unit 1 and Unit 2 surveillance data can be used in the chemistry factor determination.
i Criterion 5. The surveillance data for the correlation monitor material in the capsule should fall within the scatter band of the data base for that l
material.-
All available surveillance data used in the chemistry factor determination have correlation monitor material data which fall within the scatter band of the available data base for that material.
