Westinghouse Non-Proprietary Class 3 C-1 WCAP-18795-NP December 2022 Revision 0 APPENDIX C CHARPY V-NOTCH PLOTS FOR EACH CAPSULE INCLUDING BASELINE DATA USING SYMMETRIC HYPERBOLIC TANGENT CURVE-FITTING METHOD C.1 METHODOLOGY Contained in Table C-1 are the upper-shelf energy (USE) values that are used as input for the generation of the Charpy V-notch plots using CVGRAPH, Version 6.02. The definition for USE is given in ASTM E185-82 [C-1],
Section 4.18, and reads as follows:
upper shelf energy level - the average energy value for all Charpy specimens (normally three) whose test temperature is above the upper end of the transition region. For specimens tested in sets of three at each test temperature, the set having the highest average may be regarded as defining the upper shelf energy.
Westinghouse reports the average of all Charpy data ( 95% shear) as the USE, excluding any values that are deemed outliers using engineering judgment. Hence, the Capsule N USE values reported in Table C-1 were determined by applying this methodology to the Charpy data tabulated in Table 5-1 through Table 5-5 of this report. USE values documented in Table C-1 for the unirradiated material, as well as for Capsules V, T, R, and P, were also determined by applying the methodology described above to the Charpy impact data reported in WCAP-8193 [C-2] and WCAP-14613 [C-3]. The USE values reported in Table C-1 were used in the generation of the Charpy V-notch curves.
The lower-shelf energy values were fixed at 2.2 ft-lb for all cases. The lower-shelf lateral expansion values were fixed at 1.0 mil to be consistent with the previous capsule analysis. Similarly, the upper-shelf energy must also be fixed for curve-fitting the Charpy V-notch (CVN) Energy data using the values reported in Table C-1.
However, the upper-shelf lateral expansion is not fixed in CVGRAPH.
