1.0 INTRODUCTION

Two boat samples removed from the Niagara Mohawk Power Corporation's (NMPC) Nine Mile Point Unit 1 (NMP-1) Core Shroud were sent to McDermott Technology Inc. (MTI) Lynchburg Research Center (LRC) for analysis in 1997. Metallography examination and dosimetry analysis were performed at LRC and the test results were documented in Part I [1] and II [2] of this report, respectively. The goals of the metallography examination included:

~ document microstructural features of both samples,

~ evaluate the cracking morphologies and patterns that may be present,

~ measure the microhardness for selected locations on the metallurgical sample cross-sections,

~ examine oxides that may be present in the cracks, and

~ examine the microstructural evidence for degree of sensitization indicated for each sample.

Dosimetry analysis provided information for the neutron fluence calculation through the core shroud thickness direction.

The shroud is a right cylindrical shell that functions to direct the flow of coolant through the reactor core while operating and maintains core alignment during hypothetical accident conditions. The central-mid-cylinder (shell course) of the shroud is 176 inches inner diameter and 90.12 inches high.

It is fabricated &om two 1.5 inch thick Type 304 stainless steel plates. The plates are roll-formed into half cylinders and welded together to form a cylinder. Extensive cracking was discovered along the two long vertical welds.

These welds are designated V-9 and V-10. The central-mid-cylinder shell course surrounds the reactor core, and therefore, the materials in this vicinity are exposed to the high energy neutron flux.

The potential for irradiation assisted stress corrosion cracking (IASCC) was considered, because the reactor has been operating since 1969 and because the welds are in close proximity to the reactor core. Both samples were examined specifically for evidence of IASCC in both the cracking morphologies and in the microstructures. Both welds were cracked extensively on the outer surface,

RDD:98:55863-004-000:01 but only two short cracks were discovered on the inner surface. The outer surface cracking was confined to one plate; however it was noted that both plates from this shell course were cracked at the horizontal welds. Boat sample V-10 contains a crack. It was removed from the outer surface and was located to the right of weld V-10 approximately 57.5 inches below the upper horizontal weld, H-4. Boat sample V-9 is not cracked and was removed from the inner surface and was located to the right of weld V-9 at an elevation approximately 25 inches below the upper horizontal weld, H-4.

This latter sample represents a high fluence location and is used to determine ifmeasurable material degradation has occurred due to fluence. This sample provides material with which to measure fracture toughness'. Figure 1.1 shows the boat sample locations in the central-mid-cylinder shell course.

After reviewing the test results from metallography examination, NMPC decided to pursue the possibility to machine tension specimens from both V-9 and V-10 samples'. After carefully reviewing NMPC's request, MTI proposed the following.

1. Due to very limited material that was available for machining, miniature tension specimen should be considered. The Oak Ridge National Laboratory (ORNL) design [3] could be useful for this work.

2. To study the geometry effects, control specimens should be machined from archive materials'.

Scaling factor can then be determined from the test results to convert the test results generated &om irradiated miniature specimens to full size equivalent results. Therefore, full size, V-9 size, and V-10 size tension specimens should be machined and tested under the same

'This possibility is currently being studied by MTI.

'V-10 tension specimen machining and testing was requested by NMPC after the V-9 tension specimens were machined and tested.

'NMPC does not have core shroud archive materials. By agreement with NMPC, control specimens were machined from a 304 stainless steel plate that was supplied by Dr. Mike Manaham of MPM Research & Consultant.

I MTI RDD:98:55863-004-000:01 conditions.

2.0 SPECIMEN DESIGN PREPARATION 2.1 Specimen Design MTI studied various miniature specimen designs and concluded that the ORNL design (pin-loaded tension test specimen) was probably the best one to use in this project since (1) through careful machining, a comparable specimen geometry to ORNL's may be obtained from V-9-I and (2) although the material was different (reactor vessel steel was used in ORNL's program), material properties should be comparable since the fluences that V-9 and V-10 boat samples received were much higher compared to a PWR vessel and could result in higher embrittlement. Therefore, the V-9 tension specimen was designed using ORNL's design as guidance with minor alteration to address the limits resulting &om a very complicated machining process due to highly irradiated material. The V-9 tension specimen geometry was shown in Figure 2.1.

At the request of NMPC, MTI also studied the possibility to machine tension specimens from V-10 remaining pieces. With very limited material available for machining purpose, it was concluded that the V-10 tension specimen would be smaller than the V-9 tension specimen. Since V-9 tension specimens were machined and tested successfully, it was decided to have a scale-down version of V-9 tension specimen design for a V-10 tension specimen. Figure 2.2 shows V-10 tension specimen geometry. Note that specimen thickness was 0.030 inch [shown in Figure 2.2 (a), specimens BLV10 Pl & 2] in the planning stage but was changed to 0.025 inch [shown in Figure 2.2 (b), BLV1083 &

V10irr81] due to limited material obtained from the V-10-L sample.

Mock-up specimens were machined and tested to verify the adequacy of specimen design, equipment, and procedures.

MTI RDD:98:55863-004-000:01 2.2 Specimen Preparation In order to reduce employee radiation exposure, specimen preparation was separated into two stages.

The first stage was to machine a specimen blank using a combination of (1) low-speed sectioning in the hot cell facility to obtain a workable specimen blank and (2) this specimen blank was transferred out of the hot cell facility to the MTI Hot Machine Shop (HMS) where this specimen blank was machined into a rectangular parallelepiped shape using an electrical discharge milling (EDM) machine. The second phase of machining included:

(1) Specimen blank was sliced into several rectangular parallelepipeds with the exact specimen thickness using EDM.

(2) Specimen blank with the exact specimen thickness was placed on a pre-fabricated fixture where the tension specimen was machined using EDM (except the pin holes).

(3) The whole fixture was then removed &om the EDM and placed on a milling machine where the pin holes were machined.

(4) Specimen dimension was then verified.

Prior to machining the irradiated samples, several unirradiated mock-up samples were machined to verify the adequacy of the equipment and procedures and also to provide operators opportunity to practice to minimize exposure during actual work.

2.2.1 Sample Section Plan Both samples V-9 and V-10 were sectioned in the hot cell for the metallography work [1]. Figure 2.3 shows the specimen orientation and sectioning diagram for specimen V-9. The following table summarizes the sectioning plan for specimen V-9.

The section diagram for the control specimens is depicted in Figure 2.5. A total of two full size, two V-9 size, and three V-10 size specimens were machined. Specimen dimension in ASTM E-8 Figure 7 for a full size pin-loaded tension test specimen was used.

RDD:98:55863-004-000:01 2.2.2 Actual Specimen Machining Two tension specimens were obtained from the V-9 sample successfully and only one specimen was obtained &om the V-10-L sample despite the fact that two tension specimens were originally planned.

MTIhad to cut one side ofthe tension specimen very close to the crack so that a maximum size V-10 miniature tension specimen could be obtained. It was apparent to the operator that the primary crack was avoided. However, the EDM machine wire broke several times during the cutting process. It was concluded that the wire broke because it encountered secondary cracks which were non-conductive and were not apparent to the operator. Table 2.3 summarizes the dimension of various tension specimens for the purpose of comparison purpose.

MTI RDD:98:55863-004-000:01 servohydraulic testing machine. The test machine is interfaced with the MTS TestStar digital system. An MTI certified program TNSLTEST was used to control the machine and acquire the data during the test. All tension tests were run using stroke control with actuator travel rates of 0.0030 to 0.0075 inch per minute depending on specimen size.

Force and strain were monitored and recorded continuously throughout the duration of each test.

Force was measured with a 5 kip MTS load cell at 300 to 600 pound range depending on specimen size. Strain was measured using an MTS extensometer with 0.5 inch of available travel at 0.25 inch range. This extensometer was attached to the bottom of an ATS Linear Voltage Displacement Transducer (LVDT) that has a pair of knife edges and was placed 0.2 to 0.3 inch away to match the specimen gage length. Tests were performed in an ATS split type furnace and test temperature was controlled to within J 4 'F of the test temperature. A soak time of at least 20 minutes after reaching test temperature was used to assure uniform temperature distrubution in the specimen. The final specimen width and thickness of each broken specimen was measured using a dial caliper to determine material fracture properties.

The tension test data were analyzed using the MTI certified computer program MTADS. This program uses the load and strain data in conjunction with various specimen and testing parameters to perform a standard ASTM E8-94a analysis. Reported values for each test include yield and ultimate tensile strength, uniform and total elongation, reduction in area, fracture load, fracture stress, fracture strength, and the Ramberg-Osgood'strain hardening parameters. A summary of tension test results is reported in Table 3.1. Appendix A contains test reports, realtime data plots, and data analysis reports for each specimen.

The test results from unirradiated specimens clearly suggest that, except for the ultimate strength, the mechanical properties determined from miniature specimens are dependent on the specimen geometry. For example, the yield strength increases with increasing specimen width to specimen thickness ratio. This is shown in Figure 3.1. The original plan to use unirradiated data to establish scaling factors was not appropriate. This can be seen by applying the scaling factor to irradiated V-9 tension test results; the yield strength decreases to 33 ksi which is well below V-

MTI RDD:98:55863-004-000:01 10's results. One possible explanation for this observation is that the yield strength for unirradiated 304 stainless steel is only 22 ksi at 550 F compared to 48 ksi for irradiated 304 stainless steel at the same temperature and the scaling factor is a function of specimen geometry as well as material yield strength. Material with higher yield strength may generate test results consistent with those of full size specimens although a smaller size is used. This can be further observed in the ORNL's paper [3] where the lowest yield strength that was validated was 67 ksi (no data points below 67 ksi). For a low yield strength unirradiated 304 stainless steel, ORNL's design (similar to MTI V-9 tension specimen design) is not valid and a larger specimen design (or a lower specimen width to specimen thickness ratio) is needed.

The unirradiated test data provided the following information.

1. The test data were compared to the "certified material test report" provided by the material supplier (see Attachment B). The yield and ultimate strength are 37.4 ksi and 89.2 ksi, respectively, at room temperature. At 550 'F, the yield strength and ultimate strength are lower due to temperature effects. This is consistent with MTI's data,

2. More importantly, scatter is expected when testing miniature specimens. MTI's data suggest that scatter is minimized due to precision machining, good specimen alignment, and an accurate measuring device.

Several observations were made on the irradiated tension test data and are summarized as follows.

1. The irradiated specimens were machined from regions close to the surface areas (maximized material for machining), it was determined that the fluence for the V-9 and V-10 tension specimens was approximately 3.1x10" and 1.1xlP n/crri, respectively, per Framatome Technologies Inc.'s calculation [4].

2. The data were first compared to data published by A. J. Jacobs et al [5] where solution heat treated 304 stainless steel samples were irradiated to 8 x 10" and 2.5x10" n/cm . The yield

MTI RDD:98:55863-004-000:01 strength for the unirradiated condition and these two fluences at 550 'F were 24.9, 80.2, and 94.2 ksi, respectively. Based on Jacobs'ata, the yield strength for a 304 stainless steel sample irradiated to 1 to 3 x 10 n/cm'would range from 40 ksi to 60 ksi. MTI's data were reasonable compared to Jacobs'ata. Later, test data were forwarded to GE Nuclear Energy for review. Per discussion between GE Nuclear Energy and NMPC, the yield strength at 550

'F for 304 stainless steel irradiated to a fluence of 1 to 3 x 10~'/cm~ would be in the range of 50 ksi according to GE's design curves. This is consistent with MTI's data.

3. Margaret L. Hamilton et al [6] at Pacific Northwest Laboratory (PNL) performed a research project where solution annealed 304 stainless steel was machined into miniature specimens using various machining methods (specimen gage = 0.2 inch, specimen width = 0.04 inch, and specimen thickness = 0.01 inch). PNL's design is similar to the V-10 tension specimen (specimen gage = 0.2 inch, specimen width = 0.04 inch, and specimen thickness = 0.025 inch).

PNL specimens were tested at room temperature; the yield strength was 38 ksi and was consistent with the bulk yield strength and therefore validated their miniature specimen design. PNL test results seem to suggest that material yield strength has a strong influence on miniature specimen validity. Although PNL's'specimen has a larger specimen width to specimen thickness ratio (=4) compared to MTI's design, the test results were valid because of a higher yield strength at room temperature (38 ksi at room temperature and 22 ksi at 550

'F). In summary, PNL data are conclusive for MTI to determine that no corrections are needed for V-9 and V-10 tension specimens because of (1) a higher yield strength for the irradiated material (50 ksi compared to 38 ksi) and (2) a lower specimen width to specimen thickness ratio compared to that ofPNL gower ratio yields results close to full size specimen as shown in Figure 3.1).

At flrst glance, it is questionable why the yield strength for specimen V-9 (average = 48 ksi) is lower than that of specimen V-10 (51 ksi) since specimen V-9 (core shroud inner surface) received higher neutron fluence than specimen V-10 (core shroud outer surface). Such observation is based on the fact that specimen material, orientation, dimension, and test conditions are all identical. Discussion of those factors is summarized as follow.

1. Although V-9 and V-10 boat samples were removed &om diFerent half cylinders, NMPC has concluded that difFerences in the ma~) for those half cylinders may be small and should not impact the test results.

2. The grggiaQgg of V-9 tension specimens is in parallel to the fusion line and the center line of the tension specimen is approximately 1.10 inch from the fusion line. The specimen V-10 tension specimen is normal to the fusion line and the distance between the fusion line and specimen center line is 0.56 inch (see Figures 2.3 and 2.4). Since the V-10 tension specimen is closer to the fusion line, it is expected that the material that MTI sampled should contain HAZ metal which has higher yield strength.

3. Specimen digznsigg should not have significant impact per aforementioned discussion.

h It is concluded that material di6erences (V-10 tension specimen was a combination of HAZ and base metal and V-9 tension specimen was base metal) result in the higher yield strength for the V-10 tension specimen.

The impact of specimen geometry on the ultimate strength is small. For unirradiated material, the ultimate strength ranges from 66 ksi to 70 ksi for all geometries; while slightly higher values are observed for the irradiated material (68 ksi to 75 ksi). A slight increase in ultimate strength due to irradiation is observed.

4.0 SUMKQhY t The following conclusions can be drawn from this investigation:

1. Miniature tension specimens were successfully machined from boat samples V-9 and V-10 L

2. The yield strength for the core shroud material (base metal) ranges from 45 ksi to 51 ksi and the ultimate strength from 68 ksi to 75 ksi at 550 'F. The neutron irradiation has larger impact on the yield strength and much less impact on the ultimate strength.

3. The idea of establishing scaling factors by testing unirradiated material was not applicable due to low yield strength at 550 'F. Although miniature tension specimens were tested, it is concluded that no correction needs to be applied to irradiated yield and ultimate strength data because of the material's higher yield strength.
