1.0 INTRODUCTION

Northeast Utilities requested Westinghouse to perform an upper shelf energy evaluation for two nozzle shell plates from the Connecticut Yankee reactor vessel, plates W9807-1 and W9807-8. l This evaluation included the following: (1) Pedigree of the nozzle shell plate matenals; and (2) Charpy testing of 42 specimens from each plate. The testing material was supplied by Northeast Utilities and consisted of two slabs cut at 1/4T thickness from the Connecticut Yankee nozzle shell archive material plates identified as W9807-1 and W9807-8. A total of eighty-four Charpy specimens were fabricated, forty-two from each plate. Out of the forty-two specimens, twenty-one were cut parallel to the major rolling direction of the plate (longitudinal orientation) and twenty-one were cut perpendicular to the major rolling direction of the plate (transverse orientation). The specimens were fabricated in accordance with ASTM Specification E 23-91Ill. The Charpy V-notch tests were performed by the Nuclear Services and Materials Testing Depart-ment at the Nuclear services Division of Westinghouse,in acconiance with 10CFR50 Appendix G[21, ASTM E23-91Ill and RMF Procedure 8103, Revision 1. This data was used to determine the lis unirradiated upper shelf energy of nozzle shell plates W9807-1 and W9807-8 in accordance with ASTM E 185-82I33 1equirements. The results of this evaluation are summarized in the following sections. t All work involving the fabrication and impact testing of the charpy specimens was performed in accordance with NATD Quality Assurance Manual WCAP-9565, which meets the requirements of the Code of Federal Regulations,10 CFR Part 50 Appendix B.

SECTION 2.0 EVALUATION OF UNIRRADIATED UPPER SHELF ENERGY I FOR NOZZLE SHELL PLATES W9807-1 AND W9807-8 -l 2.1 Pedigree of Nonle Shell Plate Materials I The objective of this task was to establish the pedigree of the nonle shell plates in the Connecti-cut Yankee reactor vessel to determine if the unirradiated archive materials are of the same pedi- { gree as the reactor vessel nonle shell plate materials W9807-1 Heat No. A5887 and W9807-8 a W Heat No. B0716. Figure 2.1-1 shows the location of these plates within the beltline region i In order to perfonn this task, Westinghouse conducted a record searth within the Nuclear and - Advanced Technology Division (NATD). The information found in the record search indicated additional material representing the nonle shell plates W9807-1 (Heat No. A5887) and W9807-8 (Heat No. B0716) was obtained from Combustion Engineering and was shipped to Connecticut Yankee. In addition, dimensions of the slabs shipped to the customer and material test cenificates from the Lukens Steel Company indicating the copper composition of each plate were also found f in the record search, In order to verify the archive material at the Nonheast Utility site was the same matedal referred to in the transmittal letters found in the record search, Westinghouse personnel from NATD vis-agR l ited the Nonheast Utility site to examine the archive materials for identification markings and to j measure the dimensions of the slabs. The results of this visitindicated the identification markings j found stamped on the archive materials were W9807-1 and W9807-8 and the dimensions of the slabs were the same as those found in the record search. In addition, Westinghouse performed a chemical analysis on the archive material which showed the copper composition of each plate was exactly the same as that reponed in the matedal test certificates from the Lukens Steel Company. ' -l The nickel composition of each plate was never reponed in the material test cenificates. Tables 2.1-1 and 2.1-2 show the results of the chemical analysis for nonle shell plates W9807-1 and l W9807-8. Upon verification of the archive material, Nonheast Utilities cut slabs A and B from plates W9807-8 and W9807-1,inspectively, encompassing the 1/4T centerline as shown in Figures 2.1-2 and 2.1-3. These slabs were shipped to Westinghouse, which cut slabs C and D from plates W9807-8 and W9807-1, respectively, to fabricate and test fony-two specimens from each plate,in 7 both the longitudinal and transverse directions. ? h 2-1 I t vc

'Ihus, upon receipt of the archive mate-rial, Westinghouse had the slabs stress-relieved as shown in Table 2.2-2 to simulate all fabrication interstages and final stress relief of the actual reactor vessel materials. 1 Table 2.2-1: IIeat Weatment IIistory of the Connecticut Yankee Reactor Vessel Nozzle Shell Plates Performed by Combustion Engineering ""7) " Coolant Material (F (hrs) W9807-1 (Heat No. A5887) 1550-1600 4 Dip Quenched g' 1225 25 4 Fumace cooled W9807-8 (Heat No. B0716) Table 2.2-2: Additional Stress-Relief Performed on the Connecticut Yankee Reactor Vessel Nozzle Shell Archive Material Temperature Time Coolant Material (,F) (hrs) W9807-1 (Heat No. A5887) 1150 25 24 Furnace Cooled at 100 F/hr to 600 F W9807-8 (Heat No. B0716) T_- e a t 2-7 i

2.2.2 Fabrication of Charpy Specimens Westinghouse received two slabs, B and A, removed from the 1/4T thickness locatian from archive Connecticut Yankee nozzle shell plates W9807-1 (Heat No. A5887) and W9807-8 (Heat No. B0716), respectively. Slabs B and A had dimensions of 51/2" x 113/4" x 2.63" and 51/2" x 13 3/8" x 2.63" for plates. i From these slabs, slabs D and C were removed from plates W9807-1 and W9807-8, respectively, to cut the specimens. For each plate, twenty-one charpy specimens were onented so that the major j axis of the specimen is parallel to the surface and parallel to the principal rolling direction of the plate (longitudinal orientation), and twenty-one specimens were oriented so that the major axis of the specimen is also parallel to the surface but normal to the principal rolling direction of the plate l (tmnsverse orientation). Figures 2.2-1 and 2.2-2 show the anangement of how the specimens were cut from each slab. Specimens labeled DT301 - DT321 and DIA31 - DLO51 represent the specimens from nozzle shell plate W9807-1, oriented in the longitudinal and transverse direc-l tions, respectively. Similarly, specimens labeled CT101 - CT121 and CL001 - CLO21 represent j the specimens from nozzle shell plate W9807-8, onented in the longitudinal and tansverse direc-tions, respectively. The Chamy V-notch impact specimens were fabricated in accordance with the requirements of l ASTM E 23-91 Type A SpecimenUl. Figure 2.2-3 shows the specific dimensions used to machine l the specimens. A total of eighty-four (84) Chagy V-notch impact specimens were fabricated, forty-two from each plate. i l I i I l t i S.. t. i 2-8

l 2.2.3 Testing of Charpy Specimens The mechanical testing of the eighty-four charpy V-notch specimens was conducted at the West-inghouse Science and Technology Center. The testing was performed in accordance with 10CFR50 Appendix GM, ASTM Specification E23-91Ul, and RMF Procedure 8103, Revision I with modifications for instrumentation. Instrumented charpy tests were performed using a Tinius-Olsen M odel 74,358 J machine with General Research Instmments Model 8301 (Dynatup) instru-mentation system, feeding information into an IBM XT Computer. t With this instrumentation system, load-tin e and energy-time signais can be recorded in addition to the standard measurement of Charpy e, gy (Ep). From the load-time curve, the load to gen-eral yielding (PGY), time to general yieldmg (toy), maximum load (Pg), and time to maximum load (tu) can be determined from the load-time curve. Under certain test conditions, a sharp drop in load indicative of fast fracture was observed. The load at which fast fracture was initiated is identified as the fast fracture load (Pp), and the load at which fast fracture terminated is identified as the arrest load (P )- A The energy at maximum load (Ey) was determined by comparing the energy-time record and the load-time record. The energy at maximum load is approximately equivalent to the energy required to initiate a crack in the specimen. Therefore, the propagation energy for the crack (Ep) is the dif-ference between the total energy to fracture (Ep) and the energy at maximum load. U_ The yield stress (cy) was calculated from the threee-point bend formula having the following expression: l Oy=Po L (1) i B(W-a)2C i where L = distance between the specimen supports in the impact testing machine; B = the width of the specimen measured parallel to the notch; W = height of the specimen, measured perpendicularly to the notch; and l a = notch depth. The constant C is dependent on the notch flank angle ($), notch root radius (p), and the type of loading (i.e., pure bending or three-point bending). In three-point bending, for a Charpy specimen in which $ = 45 and p = 0.010", Equation 1 is valid with C =1.21. Therefore, for L = 4W, oy=Po L = 33 PayW (2) l 8 (W-a)2 (1.21) B (W-a)# For the charpy specimen, B = 0.394", W = 0.394", and a = 0.079", Equation 2 then reduces to: s s oy = 33.3 x P y (3) G i r 2-12 l

r where cry is in units of psi and Pay is in units oflbs. The flow stress was calculated from the average of the yield and maximum loads, also using the three-point bend formula. The percent shear was determined from postfracture hotographs using the ratio-of-areas methods in compliance with ASTM Specification A370-89D. l The lateral expansion was measured using a dial gage rig similar to that shown in the same speci-fication. t The results of the Charpy V-notch impact tests performed on the umrradiated specimens from l nozzle shell plates W9807-1 (Heat No. A5887) and W9807-8 (Heat No. B0716) are shown in Tables 2.2-3 through 2.2-10. The Charpy V-Notch impact properties for each plate are manually fitted as shown in Figures 2.2-4 through 2.2-7. In addition, the fracture appearance of each unitra-diated Charpy specimen is shown in Figures 2.2-8 through 2.2-11.

4 2.2.4 Determination of the Upper Shelf Energy ASTM E 185-82[3] defines the upper shelf energy as "the average energy value for all Charpy specimens (normally three) whose test temperature is above the upper end of the transition region" In addition,"for specimens tested in sets of three at each test temperatum, the set having the highest average may be regarded as defining the upper shelf energy". l Using the Charpy impact test results shown in Tables 2.2-3 through 2.2-10, the upper shelf energy values for nozzle shell plates W9807-1 (Heat No. A5887) and W9807-8 (Heat No. B0716) were determined per ASTM E 185-82 requirements and are shown in Tables 2.2-11 and 2.2-12. The highest USE values for each plate are shown in these tables with an

  • and are listed as 105 and 90 ft-lb in the transverse orientation and 127 and 110 ft-lb in the longitudinal orientation, for plates W9807-1 and W9807-8, respectively. These results are summanzed in Table 2.2-13 and show the upper shelf energy in the transverse direction is about 82% of the upper shelf energy in the longi-tudinal direction. This is seen consistently in both plates.
