• MONTICELLO DESIGN AND FABRICATION REQUIREMENTS The Monticello reactor vessel was designed, fabricated, inspected, ar.d tested in accordance with the American Society of Mechanical Engineers Boiler and Pressure Vessel Code Section III,* Nuclear Vessels 1965 Edition and Addenda to and including Summer 1966 Addenda, and the following additions:

1. ASME SA533 plate and Inconel material per Summer 1967 Addenda. 2. Main closure flange material per Code Case 1332-3. 3. Studs and nuts material for main closure flanges per Code Case 1335-2. 4. Main closure flange and stud shank transition radius per Code Case 1366. 5. Bearing stresses for stabilizer brackets and coefficients of thermal expansion per Winter 1967 Addenda. 6. Hagnetic particle and liquid penetrant examination per {.j'j_nter 1966 Addenda. The date of the contract between the Buyer, General Electric Company, Atomic Power Equipment Department, San Jose, California and the Seller, Chicago Bridge and Iron Company, San Francisco, California, was July 18, 1966. There are no deviations to the formal code throughout the design, fabrication, inspection and testing of the reactor vessel. Design fabrication, inspection, and test requirements in addition to those required by the B&PV code were required by the Buyer's vessel purchase specification 21Al112 (Exhibit 1). These include but are not limited to the following pertinent inspections andlor tests: 1. Established specific maximum nil ductility transition temperatures for the main closure flanges and the shell and head materials connecting to these flanges (+lO°F c-."'DT temperature) and elsewhere

(+40°F NDT temperature).

2. A fabrication test program on vessel shell material which included testing of large size tensile specimens (80% of the vessel wall thickness in diameter) both plain and welded samples. (See Exhibit 3). 3. Provisions are made for determining the effects of nuclear radiation upon the reactor vessel structural materials by supplying specimens of the vessel material to be exposed to the core irradiation at the vessel wall inside of the vessel. Pertinent certifications are contained in Exhibit 2, Manufacturer's Data Report and Vessel Certification, Chicago Bridge & Iron Company. The sUl!'lIlary of results of the detailed stress analysis is contained in Exhibit 4. H.l-l

'" 12! 8 5 MONTICELLO Plans for the vessel fabrication and assembly were described in Amendment 2 to the FDSAR, "Design Fabrication and Erection of the Reactor Vessel." Actual fabrication and assembly was accord with Section IV of Amendment 2 except for minor modifications as listed in Exhibit 5 of this report. The GE quality control of the reactor vessel was essentially as described by General Electric Quality Control Plan, Section IV of Amendment 2 to the FDSAR, except the Domestic Turnkey Projects organization of General Electric Co. also made an independent QC audit. A detailed seismic analysis of the Reactor Pressure Vessel was prepared by John Blume & Associates and was included in Appendix A along with other seismic analyses. In 1977, repairs were made to the reactor pressure vessel feedwater nozzles and safe ends to minimize damage to the feedwater nozzles due to thermal cycling. The repairs consisted of removing cladding from the nozzle blend radius and bore and the installation of a feedwater sparger interference fit thermal sleeve with a piston ring seal. These design changes invalidated the "Summary of Stress Analysis for the feedwater Nozzles" shown on page 4-14 of Exhibit 4. Details of this repair and design are contained in Exhibit 7. Also in 1977, a design change modified the CRD return line because of its susceptibility to intergranular stress corrosion cracking. The 3" CRD return line and the reactor vessel nozzle safe-end forging were removed and the nozzle was capped using a 4" diameter schedule 120 pipe cap. This design change eliminated the imposed mechanical loading for the nozzle, creating a much less severe condition than the nozzle was originally designed for. As a result of this modification, the "Summary of Stress Analysis for the 3" CRDHSR Nozzle" shown on page 4-18 of Exhibit 4, is invalidated. Details of the modification and new stress analyses are contained in design change 77M069. In 1981, new feedwater nozzle safe ends featuring a tuning fork design with a welded in thermal sleeve were installed and a section of piping upstream of each nozzle was replaced with piping of a different material. These modifications were performed to provide a significant reduction in thermal cycling of the feedwater nozzle area. The new stress analyses that replaced the "Summary of Stress Analysis for the Feedwater Nozzle" shown on page 4-14 of Exhibit 4, are contained in Exhibit 8 and Exhibit 9. In 1984 several modifications were incorporated to provide greater resistance to intergranular stress corrosion cracking. The core differential pressure and standby liquid control safe end was replaced using a safe end of similar design, but with different materials. The new stress analyses are contained in General Electric Stress Report No. 23A4llS, included in Design Change No. 83Z049C. H.1-2 REV 7 12/88 * *

• MONTICELLO The jet pump instrumentation safe end and penetration seal was replaced with the jet pump instrumentation nozzle penetration seal, using low carbon 316 to replace the original ASTM AS08 Class II material.

The new stress analyses are contained in General Electric Stress Report No. 23Al939, also included in Design Change No. 83Z049C. The core differential pressure and standby liquid control, and the jet pump instrumentation modifications invalidated the "Summary of Stress Analysis for Core Differential Pressure and Liquid Control Nozzle, Head Cooling Spray and Instrumentation Nozzles, Vent Nozzle, Instrumentation Nozzles, Jet Pump Instrumentation Nozzles, Drain Nozzle, High Pressure Seal Leak Detector Nozzle and Low Pressure Seal Leak Detector Nozzle" shown on page 4-28 of Exhibit 4. Also, in 1984, a corrosion resistant cladding overlay was applied to the inside diameter of the RV head vent nozzle and RV head cooling spray and instrumentation nozzles. The weld overlay of 308L isolated the rGSCC susceptible existing weld butter located in the weld residual stress area from the reactor coolant. As documented in General Electric Stress Report No. 23A4280, part of Design Change No. 84Z068, stress calculations performed originally at this location are still valid. The recirculation inlet and outlet nozzles were both modified during the 1984 outage. General Electric Stress Report No. 23A1627, part of Design Change No. 83Z049A, documents the analysis of the redesign and replacement of the recirculation inlet nozzle safe end and thermal sleeve, including the attachment weld and the weld overlay to the recirculation inlet nozzle. This design change invalidated the "Summary of Stress Analysis for Recirculation Inlet Nozzle" shown on page 4-22 of Exhibit 4. Bechtel Stress Report No. SR-10040-SS2 (Rev. 3), also part of Design Change No. 83Z049A, documents the analysis of the replacement of the tion outlet nozzle safe end fitting, a machined component made of SA 358 Type 316 stainless steel. The "Summary of Stress Analysis in Recirculation Outlet" shown on page 4-24 of Exhibit 4 has been invalidated by this change. In 1986, new core spray safe ends featuring a tuning fork design with a thermal sleeve were installed along with a section of piping upstream at each nozzle. This modification was performed to minimize the chance of IGSCC from occurring in the Core Spray System. The new stress analyses is documented by Bechtel Document 30l-P-S. Also in 1986, the CRD return nozzle, previously capped in 1977, was again modified. The purpose of the modification was to remove that portion of the existing weld butter layer susceptible to IGSCC, and re-clad the weld prep area with corrosion resistant cladding and install a new nozzle cap. General Electric Stress Report No. 23ASSS3, included as part of Design Change No. 86Z0l6, documents the analysis . H.I-3 REV 7 12/88

• I. Introduction
• Test procedures and results are described for tests conducted for Chicago Bridge and Iron Company of six 80 percent thickness tension specimens for Nuclear Reactor Vessel GE/APED for Northern States Power Company, Monticello, Minnesota.

The tests were conducted at the same time as similar tests for Nuclear Reactor Vessel GE/APED for Central Vermont Power Company, Vernon Vermont. Facilities of the Department of Civil Engineering, University of Illinois, Urbana, Illinois were used in accord with a Memorandum Agreement for Commercial Tests between the Department and the Chicago Bridge and Iron Company. R. N. Wright, Associate Professor of Civi 1 Engineering, supervised the testing. G. K. Sinnamon, Professor of Civi 1 Engineering, and V. J. McDonald, Associat"e Professor of Civi 1 Engineering and Principal Research Engineer, participated in planning and conduct of the tests. Instrumentation and test procedures are described in the following section. Test results are described in the last section. 2. Instrumentation and Test Procedures Test specimens were prepared by Chicago Bridge and Iron Company. Dimensions are given in their drawing T6 Rev 1 for Contract No. 9-5624 which is reproduced here as Fig. 1. Gage diameter was 4-5/16 in. and gage length 13 in. Specimens were delivered to the Department of Civil Engineering on September 11, 1967 and stored in Talbot Laboratory adjacent to the testing machine until tested during the week of January 8, 1968. Test procedures conformed with ASTM E8 66. Test temperatures ranged from 70 to 75 degrees Fahrenheit

• 3-3 The testing machine used was the University of Illinois 3,000,000 lb. capacity universal testing machine. Loads were recorded from the load indicator of the machine. Ames dial indicators with .0001 in. divisions were used in measuring elongations from zero load to approximately 1 percent strain; and Ames dial indicators with .001 in. divisions were used from zero load to maximum load. Initial gage lengths and elongations after rupture -were measured using a steel scale with .01 in. divisions.

Initial gage diameters and diameters after rupture were measured using micrometers with .001 in. divisions. Figure 2 shows a specimen in place in the testing machine with the dial indicators supported by a split ring and angle device. Diametrically opposed, spring loaded, gage points fit holes 1/16 in. diameter by 1/8 in. deep drilled into the specimens to support the rings. A third gage point between the-diametrical ones prevents rocking of the ring. The angles attached to the rings hold the two .001 in. division Ames dials at 4 1/4 in. from the axis of the specimen and the two .0001 in. division Ames dials at 6 1/4 in. from the axis of the specimen. Indicators are pulled by copper wires tached to a similar split ring and angle device. Figure 3 shows indicators in place during loading and the television cameras used to read elongations. Figure 4 shows recording of load from the load measuring system of the testing machine and recording of elongations from closed circuit television receivers. During the first two of the six tests, SR-4 electrical resistance gages were used to measure strain prior to yield in order to check upon the accuracy of the dial indicator system. SR-4 gages showed slightly greater strain during the first loading increment (50 to 100 kips) than the dial indicators; thence to yield essentially identical changes in strain were 3-4 * *

• recorded by the two procedures.

The discrepancy in the initial increments is attributable to reseating of the gage points supporting the dial indicators following the reversal _& strain direction during the preliminary steps of loading desc*ribed below. 'Only strains obtained from elongation measurements with the dial indicators are reported here. Preliminary steps of the testing consisted of centering the specimen in the upper head of the machine, recording initial elongations at zero load, fastening the lower head of the specimen and loading to 100 kips to set the grips, reducing load to 50 kips and reading elongations which were used as base values in reducing stress-strain data. Elastic range loading began with increase of load to 100 kips and reading of elongation, followed by increase of load and elongation reading in 100 kip increments. Upon noticeable yielding, a slow deformation rate was maintained, load and elongation were recorded at intervals of approximately .01 in. elongation until pronounced strain hardening at an elongation of about. 1 in. Then load was reduced and the .0001 in. dial indicators were removed. Continuous deformation was resumed; load and elonga-tion were recorded at intervals of about .05 in. elongation until maximum load was observed. Dial indicators were then removed from the specimen and it was deformed to rupture. In the first two tests somewhat fewer readings were made in the post yield range. In the inelastic range to maximum load, strain rate did not exceed .01 in./in./minute. In the elastic range stress .rate did not exceed 10,000 psi/minute. In the first test the. lower ring came loose twice during the post-yield range of testing. The deformed gage length was measured to 0.01 in. accuracy after the dial indicat'ors were removed at maximum load. This measure-ment provided a basis for computing strains from dial readings for the majority of the post yield region; a small region of uncertainty is shown by dotted lines in Fig. 5. The cause of the loosing of the lower ring was improper spring 3-5 loading of the gage points. One more loosening of the lower ring occurred in the process of obtaining proper adjustment. It was in the second test. Fig. 6, at a stress of 81.9 ksi. It was determined that dial readings were not substantially affected by the loosening and replacement.

3. Test Results Test results are summarized in Table I. Shown for each specimen are: stress-strain curves, Fig. 5 through 10; photographs of the two fracture surfaces, Fig. II through 16; and photographs of the broken specimens with fracture surfaces fitted together, Fig. 17 through 22. Specimens are identified by the numbers provided by Chicago Bridge and Iron Company and an "OT NO.'I assigned by the writer to facilitate identification of individual tests and specimens.

Table I shows that, test'results meet tensile requirements of ASTM A 533, Grade B, Class I steel. The elongation in 13 in. is not directly comparable to the standard elongation in 2 in. for a 1/2 in. diameter specimen. Larger elongation is observed because the gage length is only three times the diameter for these specimens. If, however, an additional '4-5/16 in. of gage length were considered to be present and to elongate by the 10 percent form strain typical of Fig. 5 through 10, the elongation in 17-1/4 in. would in every instance exceed 20 percent. Welded specimens, denoted by T3-2X, showed substantially the same properties as the unwelded. It is apparent in Fig. 20 through 22.that fracture of the welded specimens was ductile and occurred in the base metal well away from the weld. A clear indication of weld yielding at a stress of 67 ksi pears in Fig. 10. Possible weld yielding at 64 ksi is suggested by the strain curve shown in Fig. 9; for the stress-strain curve of Fig. 8, yielding of base metal and weld appears to have occurred simultaneously. 3-6 .' *

SUMMARY

OF STRESS ANALYSIS FOR MAIN CLOSURE FLANGES The stress analysis for the main closure flanges and the studs was conducted in accordance with requirements of GE Specification No. 21All12, Rev. 5, dated 9-30-68. Temperature distributions used in this sis are presented in Section Tl of the stress report. The minimum required stud cross-sectional area, per ASME Code, Section III, Article I-12, was found to be 1177.14 square inches (page I-Sl-7). This was based on an able stress Sm = 36,325 psi at 575°F. The actual sectional area, provided by 64 studs with 5-1/16 inch shank diameter and 7/16" extensiometerhole, is 1278.61 square inches. The average and maximum stud service stresses (per ASME III -N-4l6.l) were found to be cal during startup at 270 minutes into the transient, with their respective magnitudes being 47,929 psi and 89,824 psi (page I-Sl-84). The average stud temperature at this time is 340°F. Allowable stresses at this perature are 2 Sm = 79,280 psi for the average stress and 3 = 118,920' psi for maximum stress. The stud fatigue anlaysis was performed in accordance with Par. N-4l6.2 of ASME Code, Section III. The peak stress intensity ranges were computed at the root of the thread using a fatigue strength reduction factor of 4. The cumulative usage factor was found to be 0.5637 which is well within the allowable of 1.0 (page I-Sl-100). Subiect_ ... \ ... .... *1:' ..... I..loC .... ;:';wI .....

• CHICAGO BRiDGE 8. IRON COMPANY OAK BROO/( ENGINEERING The basic stress intensities in the main closure flanges and the adjacent top head and cylindrical shell per ASME <:. ie, Section III, N-4l4, are as follows: the maximum primary membrane stress intensity in the top hemispherical head is due to preload plus pressure loading at 1250 psi and occurs 4.379 inches above the*flange transition tion. Its magnitude is 28,620 psi (page I-Sl-64) 0 Due to the influence of the head to, flange discontinuity it is classified as a local primary membrane stress intensity.

It is seen to be less than 1.1 Sm = 29,370 psi. The maximum primary plus secondary stress intensity range occurs during the startup transient at the hemispherical head to top flange junction, and has a magnitude o*f 55,320 psi. The stress intensity range in this case is 4-6.

• 3 Sm = 80,100 psi.
• The maximum primary membrane stress intensity in the lindrical shell below the shell flange is 29,560 psi (page I-Sl-6S).

This stress intensity is due to the load plus pressure loading at 1250 psi, and is located 15 inches below the cylinder to shell flange junction. As the width of the band in which 1.1 Sm = 29,370 psi is ceeded is 8.2 inches, and the allowable width is .S/Rt = 11.746 inches, this stress intensity is classified as local. For the location of the above stress intensity band see the attached sketch. The allowable stress sity for local primary membrane stress intensity is 1.5 Sm = 40,050 psi. The maximum primary plus secondary stress intensity range in the shell flange is 47,110 psi (page I-Sl-67).

SUMMARY

OF STRESS ANALYSIS FOR OAK BROOK ENGINEERING SUPPORT SKIRT AND ITS JUNCTION TO BOTTOM HEAD Using the data contained in the contract specifications and temperatures calculated in Section T2, the stress analysis has been done in Section S2. The maximum value of seismic stress along the support skirt is 2623 psi. The maximum local membrane and bending primary stress intensity occurs at the inside point of the bottom head junction and has a value of 10,625 psi. The Code allowable at design temperature for the sum of all primary stresses is 1.5 Sm = 40,000 psi. The value of the maximum range of primary plus secondary stress intensities, which also occurs at inside point of the junction, is 55,580 psi. The Code limits this range to 3 Sm = 80,000 psi. The same point is also most critical from a fatigue standpoint. The conservatively calculated value of the fatigue usage factor at this point is 0.40.

SUMMARY

OF STRESS ANALYSIS FOR TOP HEAD AND CYLINDRICAL SHELL In this section the maximum stress intensities in the top head and cylindrical shell due to combined loadings were computed. The loadings considered were: stud load, internal pressure, dead weight of vessel and tents, insulation weight, horizontal and vertical seismic forces, horizontal jet reactions, stabilizer rod tions, local bracket and nozzle reactions, refueling lows support loads, and the'thermal loads. The maximum stress intensities and their locations were found to be as follows: the maximum general primary membrane stress intensity occurs in that portion of the cylindrical shell which is removed from gross structural .. discontinuities. Its magnitude is 26,375 psi which is within the allowable value of 1 Sm = 26,700 psi. The maximum local membrane stress intensity of 29,610 psi occurs at 15 inches below the bottom of the shell flange hub. This stress intensity was found to be local in extent and is less than the allowable value of 1.5 Sm = 40,050 psi. The maximum range of stress intensity for primary plus secondary stresses has a magnitude of 55,320 psi which is well within the allowable of 3 Sm = 80,100 psi. The location of this stress intensity is at the top of the hub of the head flange. Subject MONTICELLO REACTOR VESSEL CO",. 9-5624 Da'e_By AEE :) 6608 Checked bv, ____ Date ____ .. R .....

• An effort was made to clear completed shell rings 18 feet diameter by 10 feet 11-1/2 inches long and weighing 140,000 pounds. Although these rings could be barged to Minneapolis, the interconnecting railroad (Minneapolis, Northfield and Southern Railway) could not move the shipment from Port Cargill to the Great Northern Cedar Lake yard interchange.

The Great Northern services the Monticello area. Overland truck handling clearance checks were also unsuccessful in finding an open route to the Great Northern Railroad: therefore, half ring sections were shipped from the shop. Figure IV-3 shows the shop assembled pieces for Monticello reactor yessel *

• A l7-foot diameter support skirt extension with leveling devices attached was shipped in one piece to the site. It joined .the stub skirt on the vessel bottom head to the long skirt constructed with the drywell. as shown in Figure IV-2. A cold forming procedure was utilized to press the bottom head, shell, and top head plates. All plate material was detailed to the maximum length and width dimensions could be delivered from eastern mills and properly handled by the fabricating facility.

The shell plates were purchased in the quenched and tempered condition and cold formed utilizing approved procedures. Before starting fabrication, all plates were inspected for size, thickness, surface condition and the mill stamps properly 411bentified. Ultrasonic testing of material was done by trained 5-3 Monticello Reactor Vessel, IV-3 and qualified personnel in accordance with Code specifications. Certified mill test reports and all quality control measures were reviewed by CB&I engineers to assure compliance with material specifications. After the plates were marked and flame cut to approximate

• size, they were pressed to shape on a 6,eee-ton hydraulic press, designed by CB&I. Any minor deviation from curvature tolerances found in checking with box templates and sweeps were corrected by sizing the plates on the press. Each plate was then marked and cut to size and edges beveled semi-automatic cutting torches. To insure proper dimensions and alignment, shop assembled weldments were fit-up and match-marked prior to shipment to: the jobsite for assembly and welding together.

The bottom head was shipped in two sections consisting of (1) the knuckle course of plates with the stub skirt attached and (2) the dollar plate assembly. The dollar plate assembly was predrilled in the shop to accommodate the 121 control rod drive sleeves. The initial holes were drilled to approximately 5 inches in diameter. These holes are large enough to accommodate a boring bar cutting assembly that was used in place for the final boring of the sleeves at the site. Because of the availability of machining equipment, this assembly and predrilling work was performed at CB&I's Greenville, plant. The final drilling of the holes was performed in place at the site. 5-4 *

• e Monticello Reactor Vessel, Page IV-4 The bottom head knuckle course shop weldment was positioned and two overlay weld metal build-ups were applied (see Figure IV-4) in the two areas where the shroud support was welded to** the bottom head. These weld build-ups were shop maChined to the contours shown in Figure IV-4. The Monticello vessel shell was made up of four rings, approximately 11 feet wide. Each ring was made from two formed plates. The half ring sections were temporarily welded and placed on a roller bed. The ring was preheated and the overlay weld metal deposited with automatic equipment similar to that shown in Figure IV-s. All shell fittings were shop installed.

Postweld e heat treatment was performed and inspection of the overlay weld deposit and insert seams was made after cool-down. The shell and head flanges were shipped directly to the site as rough machined, non-drilled, seamless forged rings from the Ladish Company plant in CUdahy, Wisconsin. The weld ends were prepared at the forge works (Ladish) for fit-up and welding to the adjacent No. 4 shell ring and top head weldment.

• This top head assembly was shipped in one piece. It was welded together from six knuckle plates and a one-piece dollar plate assembly, as shown in Figure IV-6. The internal .shroud support was completely shop fabricated, e including preliminary machining, at Greenville and shipped as an integral ring assembly to the site where it was welded in place to the bottom head. The final machining was completed after welding. 5-5 Monticello Reactor Vessel, Page IV-S The stud bolts, washers, and gaskets were shipped directly from General Electric qualified manufacturers to the jobsite storeroom.

4.3 SITE SUBASSEMBLY AND ERECTION Site subassembly of the" reactor vessel started about three months after work began on the containment vessel. Erection of the reactor bottom head followed the completion of the leak rate test of the drywell. The bottom head and stub skirt was welded to the reactor support skirt which was attached to the drywell prior to the leak rate test. Unlike the case for determining the maximum size of subassemblies at the shop, weight of the lifts or derrick capacity dictated the subassemblies that could be made at the site. The closure seams between subassembled sections were made in place. The postweld heat treatment zones were established by the location of penetrations with respect to circumferential weld joints and the adherence to safe thermal gradients through adjacent vessel materials. Methods of achieving the machined surface requirements, drilling and tapping and boring operations were developed by CB&I engineers using commercial equipment, where available, and designing and building custom-made devices, where necessary. 5-6 e e",; l Monticello Reactor Vessel, Page IV-6

• Suitable weather protection devices were provided to shelter the vessel weldments during ground assembly, welding, and postweld heat treatment.

The postweld heat treatment furnaces were also used for environmental housings for the welding and radiographic work. Figure IV-7 shows typical postweld heat of the longitudinal ring welds. Figures IV-8 and IV-9 similarly show postweld heat treatment of the bottom head and stub skirt assembly and the top head and flange assembly. Temperatures from thermocouples were permanently recorded on .a multiple point potentiometer instrument. Adequate thermocouples were used to obtain representative readings from all parts of the section being heated. The various parameters for heat treating, such as heating and cooling rate, variation of temperature during holding period, etc., were in accordance with Section III of the ASME Boiler and Pressure Vessel Code and other requirements of the General Electric specifications. 4.3.1 Site Subassembly The basic assembly yard fabrication process was performed as follows on the head and shell components: (a) shell halves joined .into rings, bottom head to skirt extension, head to flange on level work tables: (b) preheat to 300 0 F to 400 0 F and weld sections 5-7 Monticello Reactor Vessel, Page IV-7 together; i.e., four shell rings, one bottom head with skirt and one top head with flange: (c) magnetic particle check weld periodically during deposition of metal as preliminary inspection step and replace any unsound material found therein; (d) hot ultrasonic test welds before postweld heat treatment: (e) post weld heat treat at 11SOoF; (f) cool and radiograph welds; (g) ultrasonic welds again: (h) manual overlay welds: (i) postweld heat treat: (j) cool and ultrasonic overlay: (k) dye check overlay. 4.3.2 Assembly and Machining The bottom head and stub support'skirt assembly was set in place, leveled, and welded on a l7-foot diameter tubular support skirt furnished in the drywell base of the containment structure. The vessel centerline was established as a vertical line of sight using a precise jig transit instrument located below the bottom head and sighting on a target in the geometric center of the center control rod drive penetration. The leveling and plumbing procedure was repeated after placement of each of the four shell rings. The centerline for the bottom head and skirt assembly was located as shown in Figure IV-10. . The No. 1 shell ring, assembled and in the asser..bly yard, was placed as an integral ring in position atop the bottom head. The girth seam was fit, preheated and hand welded. The No. 2 ring was then placed, fit and welded. The preheat was maintained on 5-8 * *

• bottom head to No. 1 ring girth seam until the No. 1 to No. 2 girth seam was ready for postweld heat treatment.

At that time, the two rings were postweld heat treated simultaneously in the ternporarj furnace. Steps (b) through (k) used for site subassembly.(Paragraph 4.3.1) were used for assembly in place. Non-destructive testing methods in the field were the as those performed in the shop. Radiography was performed utilizing a 75 to 100 Curie Gamma source with appropriate shielding. Usage of the source was in accordance with the applicable Federal and State regulations.

• Concurrent with erection of the vessel shell, the vessel top head weldment was fit and welded to the cover flange in the yard area. After completion of all the welding, postweld heat treatment and examination steps, the top head was positioned for drilling the 5-l!4-inch diameter bolt holes, as shown in Figure IV-ll. With the cover in this same position, the grooves for the two 1!2-inch diameter stainless "0" ring gaskets were machined with the portable CB&I equipment as depicted in Figure IV-12. After the No. 1 and No. 2 girth seams were postweld heat treated, the temporary furnace was converted into an air-conditioned and ventilated work room around the bottom head and No. 1 shell ring. A temporary cover was installed above this work area so .the balance of the vessel could be erected without interfering with 5-9 Monticello Reactor Vessel, Page IV-9 the bottom head work. The holes and sleeves for the 121 6-inch control rod drive thimbles and the 40 2-inch diameter holes for the in-core flux sensors were machined utilizing precision-oored guide templates, optically aligned in a temperature"controlled housing to guide a verticle boring bar and cutter head, as shown in IV-13. These methods not only assured that the holes . were on accurate centers but that they were plumb. The vessel closure flange was drilled and tapped in the assembly yard after it was welded to the No.4 shell ring. The gasket sealing face on the vessel flange was machined in the assembly yard using the sarne equipment that was used for the top head flange. Drilling of the control rod drive sleeve holes, welding the sleeves and boring them to the final precision dimension was performed in parallel with the work on the vessel as described above. 4.3.3 Cleanina and Hydrostatic Test Upon completion of the machining work on the control rod drive sleeves, the reactor head was attached to the vessel in preparation for cleaning.

The cleaning of the interior surfaces of the vessel was done using high pressure (approximately 8000 PSI) deionized water containing SaO-ppm by of TSP. Special care was taken to thoroughly water-blast rinse all areas and crevices to 5-10 *

• Monticello Reactor Vessel, Page IV-10
• insure complete removal of the TSP solution.

The rinsing continued until the effluent conductivity was 5 micro-mho/em. Upon completion of the initial cleaning, the vessel was filled with heated deionized water and tested per the requirements of t..'1e ASME Code. Upon completion of the overload pressure test,

• the vessel head was removed and service gaskets installed.

The vessel head was then replaced and a leakage rate test was performed between the double "0" ring seals at the design pressure. Upon completion of the hydrostatic test at design pressure, the test caps were removed from the vessel and replaced wit..'1 temporary covers. The vessel was once again nigh pressure blasted .i th deionized water. After drying the interior surfaces of the vessel, the vessel was sealed to prevent entry of dirt or other foreign materials. 404 REACTOR VESSEL QUALITY CONTROL 4.4.1 Objective The quality control for the Monticello nuclear reactor was directed by a Quality Control Manager with the assistance of Quality Control Coordinators. The primary objective of this group was to coordinate CB&I's many quality connected functions into a system which assured that the reactor produced would meet the ..

• sualit y requirements and to document the fact that these quality equirements were met. 5-11 Monticello Reactor Vessel, Page IV-ll 4.4.2 Project Quality Control Oraanization Authority lines for project management and project quality control were separated by having both managers report directly to the Regional Operations Manager, who, in turn, reported to the Vice President and Manager of Operations.

Company standards and policies for quality control --or more aptly, quality assurance were" set by the Quality Control Administrator, who also reported to Vice President and Manager of Operations. The latter was on the same level as the Vice President and Manager of Welding and Inspection. The Q.C. Coordinator for manufacturing was concerned with only nuclear reactors. The Q.C. Coordinator for engineering, purchasing, and construction was concerned with this vessel from the date of contract until vessel completion.

4.4.3 Compliance

with Specifications By using check-off type records, spot Checking operations as the work progressed, and by auditing all inspections, the plant and site Q.C. Coordinators were able to assure that: 1. Approved procedures were used; 2. The approved procedures were being followed:

3. Required inspections were properly performed:

4. Inspections were witnessed by the customer's Q.C. representative; and 5. The material or part met the required level of quality before it was further processed.

See Figures 2 and l for dimensions and materials for determining gap. f. The leakage gap (i.e., radial gap) increases at the rate of 0.0017 inch per year due to corrosion.

g. The leakage flow velocity averaged over the annulus area at the discrete point of interest shall be used in determining C? and from Figures 4 and 6 except for zoroes C and D. Use the maximum average leakage velocity in ,one C to mine C 2 and C4 and use these values for all of zone C. Assume that the leakage velocity varies from the zone C value to zero at point D. 5.

The analysis is concerned with Service Level A, B,*and C events, and design conditions. A fatigue analysis was also performed. This analysis of the feedwater nozzle and safe end assembly is required because of the complete redesign of the existing safe end and thermal sleeve assembly. As a consequettce of this redesign, the component's geometries will from the ones originally analyzed, thus necessitating this report. The nozzle and safe end assembly in this report are analyzed in accordance with the requirements of the ASHE Code (Reference 6.2), and the General Electric design specification (Reference 6.1).

NEBG-a07 A (6/10) 8-52 NUCLEAR ENERGY BUSINESS GROUP GENERAL. ELECTRIC 22A74S4 REV 1 SH NO. 51 4.1 Thermal Transient Analysis. The only feedwater nozzle thermal transient for the vossel operating conditions (Sorvice Levels A and B) is defined in the dosign specification (Reference 6.1). This transient is also illustrated in Figure 4.1-1 for convenience. In order to simplify the thermal analysis, the feodwater transient was idealized as two separate transients (a heatup and cooldowu). These idealized transients are illustrated in Figure 4.1-2. Notice the step change in temperatures were simulated by steep ramps. This was done to facilitate numerical convergence and rosults in slightly nonconservative strosses. For moro detailod information on the two idealized tranSients, aoe Reference 6.1. 4.i.1 Thermal Model. Th.o uisymmetric finite element model of the feedwater nozzle is shown in Figure The model is made up of 2-D axisymmetric isoparametric tomperature elements (STIF 55, Reference 6.3). A portion of the vessol wall was modeled as a disc for convenience of analysis since the effect of this approximation on the temperature solutions in the regions of interest is insignificant. The model ends (RPV, thermal sleeve, and safe end) are considered constant for all temperatures. The thermal properties used are as follows. Thermal properties are those of approximately 360°F.

The stress analysis is broken into three separate thermal stresses, mechanical load stresses, and pressure stresses. The stress intensities for these three cases are then summed up to yield the total primary plus secondary stress intensity. A fatigue analysis is then performed to obtain the fatigue usage factor for the system. 4.2.1 Selected Locations for Stress Evaluation, The sections showu in Figure 4.2.1-1 are the locations selected for stress evaluation. Finite element stresses are integrated across each section to dettrmine the equivalent membrane, bending, and peak stresses. This yas done by averaging the stress across the section and linearizing the stress distribution through the section thickness as shoYn in Figure 4.2.1-2. These calculations yere performed using an engineering aid computer program 'NONO'.

ELECTRIC 22A74S4 SH NO. 89 BUSINESS GROUP REV 1 --------___ ____ ---J. 4.2.2 Thermal Stress Analysis, The thermal stresses were obtained using the element computer program ANSYS. The same finite element model used for the thermal transient analysis (Figure 4.1.1-1) was also used for the thermal stress analysis. However, instead of temperature elements being used, 2-D axisymmetric isoparametric stress elements (STIF-42, Reference 6.3) were used. The modeling of the portion of the vessel wall as a disc is a conservative assumption for the thermal stress solutions since the inplane radial stiffness of a disc is higher than that of a shell. The applied boundary condition at the isolated surfaces of the vessel, safe end. and thermal sleeve is the generalized plane strain condition. The elastic properties used were considered constant for all temperatures. These properties are: Carbon Steel E = 27.2 x 10 6. psi a = 7.33 x 10-6 in./in. = 0.3 0.283 Ibf/in. 3 p = Stainless Steel E = 26.85 x 10 6 psi a = 9.87 x 10-6 in.lin. = 0.3 0.29 Ib fl in. 3 p ..

The modeling of the portion. of the ves'sel "a11 as a disc is a nonconservative assumption. It is recognized that the pressure .tresses in the vessel "all regions obtained from using this model are not .trictly valid. Ho"ever, stresses in the safe end-thermal sleeve regions are valid since the effect of this modeling in these regions is insignificant. The applied boundary condition at the isolated surfaces of the safe end and thermal .leeve "as the equivalent meridional stress caused by the pressure. The vessel boundary condition was the average of the hoop and meridional stresses. 4.2.4.1 Pressure Stress Analysis Results. The pressure stresses were evaluated for the specified pressures of 1,111 psig nozzle pressure and 1,000 psig vessel pressure. The pressure membrane plus bending stresses are tabulated in Table 4.2-9. The pressure membrane'plus bending plus peak stresses are tabulated in Table 4.2-18.

Using the total alternating stress levels found in Table 4.3-2, the fatigue usage factor can be solved. From the design specification (Reference 6.1), there are 1,500 thermal cycles and it is assumed there are 10 seismic cycles. Using Figures and I-9.1 from Reference 6.2. the fatigue usage factors are found. Table 4.3.3-1 contains these calculations. Notice, the stress ranges must be adjusted to the elastic modulus of the fatigue curves. The total usage factors are as follows.

Hay 7, 1981, respectively. the manufacturing deviations on the The deviations are described in detail dated April 29, 1981. July 2. 81. and 30.1 Deviations Due to DDR Number 15127. The deviations reported within DDR Number 15127 are two undersize locations on the thermal sleeve pads. The undersize amounts are two mils and four mils on the 7.812 inch diameter and the 7.625 inch diameter, respectively. It is noted. however. that the deviations are on the thermal sleeve pads. and within the previous calculations the pads are neglected conservatively. Therefore. these deviations will have no effect on the previous analysis and will not require recalculations of stresses. 30.2 Deviations Due to DDR Number 26521, 'The deviation reported in DDR Number 15140 is a tool undercut along the tapered surface the 10.84 inch diameter zone and the 12.00 inch diameter zone. However. this tool undercut was weld repaired. heat treated. and machined to original finish size. This type of repair is allowed per ASME Code, Reference 6.2. Post-weld heat treatment ensures stress relief and an acceptable metallurgical condition. The part is restored to the original specified dimensions. Therefore, these deviations will have no effect on the previous analysis and requires no recalculation of stresses. 30.3 Deviations Due to DDR Number 15139. This paragraph analyzes the effects of two manufacturing deviations on the Monticello feedwater safe end. The deviations are described in detail in DDR Number 15139. dated April 30. 1981. and illustrated on Figure 30.3-1. 30.3.1 Summary of Results.

30.3.3 Primary Plus Secondary Stress Analysis. This portion of the report discusses the detailed stress evaluation of the thermal stress, pressure stress, mechanical stress, stress ranges. and fatigue usage for selected locations of the geometry. 30.3.3.1 Thermal Stress. Sections F and G are thinner than their corresponding sections in the previous nominal calculations. The reduction in thickness for these sections is 1.65 percent and 2.3 percent (Section F and G. respectively). This small change will have no significant effect on the heat transfer coefficients and thus "ill be' directlt to the change in the biot's number. For Section F, the biot's numbers before-and after the reduction are 1.067 and 1.0494, respectively. For Section G, the biot's numbers before and after are 1.1785 and 1.1514, respectively. For both sections, the biot number is in a range that the small percentage change in it due to the thickness change will have no significant impact on the stresses in the region *. This, along with the f.act that, as the thicknesses are reduced, the relative stiffnesses are lowered, causing thermal stresses. "hich are secondary or displacement controlled stresses, to be lowered. Therefore. the stresses obtained in the previous nominal calculations "ill be conservatively used here. 30.3.3.2 Mechanical Load Stress, The stresses obtained by mechanical loading are to accollDt for the reduced thicknesses

• MONTICELLO DESIGN AND FABRICATION REQUIREMENTS The Monticello reactor vessel was designed, fabricated, inspected, ar.d tested in accordance with the American Society of Mechanical Engineers Boiler and Pressure Vessel Code Section III,* Nuclear Vessels 1965 Edition and Addenda to and including Summer 1966 Addenda, and the following additions:

1. ASME SA533 plate and Inconel material per Summer 1967 Addenda. 2. Main closure flange material per Code Case 1332-3. 3. Studs and nuts material for main closure flanges per Code Case 1335-2. 4. Main closure flange and stud shank transition radius per Code Case 1366. 5. Bearing stresses for stabilizer brackets and coefficients of thermal expansion per Winter 1967 Addenda. 6. Hagnetic particle and liquid penetrant examination per {.j'j_nter 1966 Addenda. The date of the contract between the Buyer, General Electric Company, Atomic Power Equipment Department, San Jose, California and the Seller, Chicago Bridge and Iron Company, San Francisco, California, was July 18, 1966. There are no deviations to the formal code throughout the design, fabrication, inspection and testing of the reactor vessel. Design fabrication, inspection, and test requirements in addition to those required by the B&PV code were required by the Buyer's vessel purchase specification 21Al112 (Exhibit 1). These include but are not limited to the following pertinent inspections andlor tests: 1. Established specific maximum nil ductility transition temperatures for the main closure flanges and the shell and head materials connecting to these flanges (+lO°F c-."'DT temperature) and elsewhere

(+40°F NDT temperature).

2. A fabrication test program on vessel shell material which included testing of large size tensile specimens (80% of the vessel wall thickness in diameter) both plain and welded samples. (See Exhibit 3). 3. Provisions are made for determining the effects of nuclear radiation upon the reactor vessel structural materials by supplying specimens of the vessel material to be exposed to the core irradiation at the vessel wall inside of the vessel. Pertinent certifications are contained in Exhibit 2, Manufacturer's Data Report and Vessel Certification, Chicago Bridge & Iron Company. The sUl!'lIlary of results of the detailed stress analysis is contained in Exhibit 4. H.l-l

'" 12! 8 5 MONTICELLO Plans for the vessel fabrication and assembly were described in Amendment 2 to the FDSAR, "Design Fabrication and Erection of the Reactor Vessel." Actual fabrication and assembly was accord with Section IV of Amendment 2 except for minor modifications as listed in Exhibit 5 of this report. The GE quality control of the reactor vessel was essentially as described by General Electric Quality Control Plan, Section IV of Amendment 2 to the FDSAR, except the Domestic Turnkey Projects organization of General Electric Co. also made an independent QC audit. A detailed seismic analysis of the Reactor Pressure Vessel was prepared by John Blume & Associates and was included in Appendix A along with other seismic analyses. In 1977, repairs were made to the reactor pressure vessel feedwater nozzles and safe ends to minimize damage to the feedwater nozzles due to thermal cycling. The repairs consisted of removing cladding from the nozzle blend radius and bore and the installation of a feedwater sparger interference fit thermal sleeve with a piston ring seal. These design changes invalidated the "Summary of Stress Analysis for the feedwater Nozzles" shown on page 4-14 of Exhibit 4. Details of this repair and design are contained in Exhibit 7. Also in 1977, a design change modified the CRD return line because of its susceptibility to intergranular stress corrosion cracking. The 3" CRD return line and the reactor vessel nozzle safe-end forging were removed and the nozzle was capped using a 4" diameter schedule 120 pipe cap. This design change eliminated the imposed mechanical loading for the nozzle, creating a much less severe condition than the nozzle was originally designed for. As a result of this modification, the "Summary of Stress Analysis for the 3" CRDHSR Nozzle" shown on page 4-18 of Exhibit 4, is invalidated. Details of the modification and new stress analyses are contained in design change 77M069. In 1981, new feedwater nozzle safe ends featuring a tuning fork design with a welded in thermal sleeve were installed and a section of piping upstream of each nozzle was replaced with piping of a different material. These modifications were performed to provide a significant reduction in thermal cycling of the feedwater nozzle area. The new stress analyses that replaced the "Summary of Stress Analysis for the Feedwater Nozzle" shown on page 4-14 of Exhibit 4, are contained in Exhibit 8 and Exhibit 9. In 1984 several modifications were incorporated to provide greater resistance to intergranular stress corrosion cracking. The core differential pressure and standby liquid control safe end was replaced using a safe end of similar design, but with different materials. The new stress analyses are contained in General Electric Stress Report No. 23A4llS, included in Design Change No. 83Z049C. H.1-2 REV 7 12/88 * *

• MONTICELLO The jet pump instrumentation safe end and penetration seal was replaced with the jet pump instrumentation nozzle penetration seal, using low carbon 316 to replace the original ASTM AS08 Class II material.

The new stress analyses are contained in General Electric Stress Report No. 23Al939, also included in Design Change No. 83Z049C. The core differential pressure and standby liquid control, and the jet pump instrumentation modifications invalidated the "Summary of Stress Analysis for Core Differential Pressure and Liquid Control Nozzle, Head Cooling Spray and Instrumentation Nozzles, Vent Nozzle, Instrumentation Nozzles, Jet Pump Instrumentation Nozzles, Drain Nozzle, High Pressure Seal Leak Detector Nozzle and Low Pressure Seal Leak Detector Nozzle" shown on page 4-28 of Exhibit 4. Also, in 1984, a corrosion resistant cladding overlay was applied to the inside diameter of the RV head vent nozzle and RV head cooling spray and instrumentation nozzles. The weld overlay of 308L isolated the rGSCC susceptible existing weld butter located in the weld residual stress area from the reactor coolant. As documented in General Electric Stress Report No. 23A4280, part of Design Change No. 84Z068, stress calculations performed originally at this location are still valid. The recirculation inlet and outlet nozzles were both modified during the 1984 outage. General Electric Stress Report No. 23A1627, part of Design Change No. 83Z049A, documents the analysis of the redesign and replacement of the recirculation inlet nozzle safe end and thermal sleeve, including the attachment weld and the weld overlay to the recirculation inlet nozzle. This design change invalidated the "Summary of Stress Analysis for Recirculation Inlet Nozzle" shown on page 4-22 of Exhibit 4. Bechtel Stress Report No. SR-10040-SS2 (Rev. 3), also part of Design Change No. 83Z049A, documents the analysis of the replacement of the tion outlet nozzle safe end fitting, a machined component made of SA 358 Type 316 stainless steel. The "Summary of Stress Analysis in Recirculation Outlet" shown on page 4-24 of Exhibit 4 has been invalidated by this change. In 1986, new core spray safe ends featuring a tuning fork design with a thermal sleeve were installed along with a section of piping upstream at each nozzle. This modification was performed to minimize the chance of IGSCC from occurring in the Core Spray System. The new stress analyses is documented by Bechtel Document 30l-P-S. Also in 1986, the CRD return nozzle, previously capped in 1977, was again modified. The purpose of the modification was to remove that portion of the existing weld butter layer susceptible to IGSCC, and re-clad the weld prep area with corrosion resistant cladding and install a new nozzle cap. General Electric Stress Report No. 23ASSS3, included as part of Design Change No. 86Z0l6, documents the analysis . H.I-3 REV 7 12/88

• I. Introduction
• Test procedures and results are described for tests conducted for Chicago Bridge and Iron Company of six 80 percent thickness tension specimens for Nuclear Reactor Vessel GE/APED for Northern States Power Company, Monticello, Minnesota.

The tests were conducted at the same time as similar tests for Nuclear Reactor Vessel GE/APED for Central Vermont Power Company, Vernon Vermont. Facilities of the Department of Civil Engineering, University of Illinois, Urbana, Illinois were used in accord with a Memorandum Agreement for Commercial Tests between the Department and the Chicago Bridge and Iron Company. R. N. Wright, Associate Professor of Civi 1 Engineering, supervised the testing. G. K. Sinnamon, Professor of Civi 1 Engineering, and V. J. McDonald, Associat"e Professor of Civi 1 Engineering and Principal Research Engineer, participated in planning and conduct of the tests. Instrumentation and test procedures are described in the following section. Test results are described in the last section. 2. Instrumentation and Test Procedures Test specimens were prepared by Chicago Bridge and Iron Company. Dimensions are given in their drawing T6 Rev 1 for Contract No. 9-5624 which is reproduced here as Fig. 1. Gage diameter was 4-5/16 in. and gage length 13 in. Specimens were delivered to the Department of Civil Engineering on September 11, 1967 and stored in Talbot Laboratory adjacent to the testing machine until tested during the week of January 8, 1968. Test procedures conformed with ASTM E8 66. Test temperatures ranged from 70 to 75 degrees Fahrenheit

• 3-3 The testing machine used was the University of Illinois 3,000,000 lb. capacity universal testing machine. Loads were recorded from the load indicator of the machine. Ames dial indicators with .0001 in. divisions were used in measuring elongations from zero load to approximately 1 percent strain; and Ames dial indicators with .001 in. divisions were used from zero load to maximum load. Initial gage lengths and elongations after rupture -were measured using a steel scale with .01 in. divisions.

Initial gage diameters and diameters after rupture were measured using micrometers with .001 in. divisions. Figure 2 shows a specimen in place in the testing machine with the dial indicators supported by a split ring and angle device. Diametrically opposed, spring loaded, gage points fit holes 1/16 in. diameter by 1/8 in. deep drilled into the specimens to support the rings. A third gage point between the-diametrical ones prevents rocking of the ring. The angles attached to the rings hold the two .001 in. division Ames dials at 4 1/4 in. from the axis of the specimen and the two .0001 in. division Ames dials at 6 1/4 in. from the axis of the specimen. Indicators are pulled by copper wires tached to a similar split ring and angle device. Figure 3 shows indicators in place during loading and the television cameras used to read elongations. Figure 4 shows recording of load from the load measuring system of the testing machine and recording of elongations from closed circuit television receivers. During the first two of the six tests, SR-4 electrical resistance gages were used to measure strain prior to yield in order to check upon the accuracy of the dial indicator system. SR-4 gages showed slightly greater strain during the first loading increment (50 to 100 kips) than the dial indicators; thence to yield essentially identical changes in strain were 3-4 * *

• recorded by the two procedures.

The discrepancy in the initial increments is attributable to reseating of the gage points supporting the dial indicators following the reversal _& strain direction during the preliminary steps of loading desc*ribed below. 'Only strains obtained from elongation measurements with the dial indicators are reported here. Preliminary steps of the testing consisted of centering the specimen in the upper head of the machine, recording initial elongations at zero load, fastening the lower head of the specimen and loading to 100 kips to set the grips, reducing load to 50 kips and reading elongations which were used as base values in reducing stress-strain data. Elastic range loading began with increase of load to 100 kips and reading of elongation, followed by increase of load and elongation reading in 100 kip increments. Upon noticeable yielding, a slow deformation rate was maintained, load and elongation were recorded at intervals of approximately .01 in. elongation until pronounced strain hardening at an elongation of about. 1 in. Then load was reduced and the .0001 in. dial indicators were removed. Continuous deformation was resumed; load and elonga-tion were recorded at intervals of about .05 in. elongation until maximum load was observed. Dial indicators were then removed from the specimen and it was deformed to rupture. In the first two tests somewhat fewer readings were made in the post yield range. In the inelastic range to maximum load, strain rate did not exceed .01 in./in./minute. In the elastic range stress .rate did not exceed 10,000 psi/minute. In the first test the. lower ring came loose twice during the post-yield range of testing. The deformed gage length was measured to 0.01 in. accuracy after the dial indicat'ors were removed at maximum load. This measure-ment provided a basis for computing strains from dial readings for the majority of the post yield region; a small region of uncertainty is shown by dotted lines in Fig. 5. The cause of the loosing of the lower ring was improper spring 3-5 loading of the gage points. One more loosening of the lower ring occurred in the process of obtaining proper adjustment. It was in the second test. Fig. 6, at a stress of 81.9 ksi. It was determined that dial readings were not substantially affected by the loosening and replacement.

3. Test Results Test results are summarized in Table I. Shown for each specimen are: stress-strain curves, Fig. 5 through 10; photographs of the two fracture surfaces, Fig. II through 16; and photographs of the broken specimens with fracture surfaces fitted together, Fig. 17 through 22. Specimens are identified by the numbers provided by Chicago Bridge and Iron Company and an "OT NO.'I assigned by the writer to facilitate identification of individual tests and specimens.

Table I shows that, test'results meet tensile requirements of ASTM A 533, Grade B, Class I steel. The elongation in 13 in. is not directly comparable to the standard elongation in 2 in. for a 1/2 in. diameter specimen. Larger elongation is observed because the gage length is only three times the diameter for these specimens. If, however, an additional '4-5/16 in. of gage length were considered to be present and to elongate by the 10 percent form strain typical of Fig. 5 through 10, the elongation in 17-1/4 in. would in every instance exceed 20 percent. Welded specimens, denoted by T3-2X, showed substantially the same properties as the unwelded. It is apparent in Fig. 20 through 22.that fracture of the welded specimens was ductile and occurred in the base metal well away from the weld. A clear indication of weld yielding at a stress of 67 ksi pears in Fig. 10. Possible weld yielding at 64 ksi is suggested by the strain curve shown in Fig. 9; for the stress-strain curve of Fig. 8, yielding of base metal and weld appears to have occurred simultaneously. 3-6 .' *

SUMMARY

OF STRESS ANALYSIS FOR MAIN CLOSURE FLANGES The stress analysis for the main closure flanges and the studs was conducted in accordance with requirements of GE Specification No. 21All12, Rev. 5, dated 9-30-68. Temperature distributions used in this sis are presented in Section Tl of the stress report. The minimum required stud cross-sectional area, per ASME Code, Section III, Article I-12, was found to be 1177.14 square inches (page I-Sl-7). This was based on an able stress Sm = 36,325 psi at 575°F. The actual sectional area, provided by 64 studs with 5-1/16 inch shank diameter and 7/16" extensiometerhole, is 1278.61 square inches. The average and maximum stud service stresses (per ASME III -N-4l6.l) were found to be cal during startup at 270 minutes into the transient, with their respective magnitudes being 47,929 psi and 89,824 psi (page I-Sl-84). The average stud temperature at this time is 340°F. Allowable stresses at this perature are 2 Sm = 79,280 psi for the average stress and 3 = 118,920' psi for maximum stress. The stud fatigue anlaysis was performed in accordance with Par. N-4l6.2 of ASME Code, Section III. The peak stress intensity ranges were computed at the root of the thread using a fatigue strength reduction factor of 4. The cumulative usage factor was found to be 0.5637 which is well within the allowable of 1.0 (page I-Sl-100). Subiect_ ... \ ... .... *1:' ..... I..loC .... ;:';wI .....

• CHICAGO BRiDGE 8. IRON COMPANY OAK BROO/( ENGINEERING The basic stress intensities in the main closure flanges and the adjacent top head and cylindrical shell per ASME <:. ie, Section III, N-4l4, are as follows: the maximum primary membrane stress intensity in the top hemispherical head is due to preload plus pressure loading at 1250 psi and occurs 4.379 inches above the*flange transition tion. Its magnitude is 28,620 psi (page I-Sl-64) 0 Due to the influence of the head to, flange discontinuity it is classified as a local primary membrane stress intensity.

It is seen to be less than 1.1 Sm = 29,370 psi. The maximum primary plus secondary stress intensity range occurs during the startup transient at the hemispherical head to top flange junction, and has a magnitude o*f 55,320 psi. The stress intensity range in this case is 4-6.

• 3 Sm = 80,100 psi.
• The maximum primary membrane stress intensity in the lindrical shell below the shell flange is 29,560 psi (page I-Sl-6S).

This stress intensity is due to the load plus pressure loading at 1250 psi, and is located 15 inches below the cylinder to shell flange junction. As the width of the band in which 1.1 Sm = 29,370 psi is ceeded is 8.2 inches, and the allowable width is .S/Rt = 11.746 inches, this stress intensity is classified as local. For the location of the above stress intensity band see the attached sketch. The allowable stress sity for local primary membrane stress intensity is 1.5 Sm = 40,050 psi. The maximum primary plus secondary stress intensity range in the shell flange is 47,110 psi (page I-Sl-67).

SUMMARY

OF STRESS ANALYSIS FOR OAK BROOK ENGINEERING SUPPORT SKIRT AND ITS JUNCTION TO BOTTOM HEAD Using the data contained in the contract specifications and temperatures calculated in Section T2, the stress analysis has been done in Section S2. The maximum value of seismic stress along the support skirt is 2623 psi. The maximum local membrane and bending primary stress intensity occurs at the inside point of the bottom head junction and has a value of 10,625 psi. The Code allowable at design temperature for the sum of all primary stresses is 1.5 Sm = 40,000 psi. The value of the maximum range of primary plus secondary stress intensities, which also occurs at inside point of the junction, is 55,580 psi. The Code limits this range to 3 Sm = 80,000 psi. The same point is also most critical from a fatigue standpoint. The conservatively calculated value of the fatigue usage factor at this point is 0.40.

OF RESULTS -STRESS ANALYSIS OF SHROUD SUPPORT The static analysis of Subsection C of Section S3 cates that requirements for the secondary brane plus bending combined with local membrane, local and general primary membrane and also primary bending stress intensities, have been met. The maximum secondary membrane plus bending combined with local membrane stress intensities of 23,970 psi occurs at point 5 of the main shell (see page S3-57), and 26,099 psi occurs at point 17 of the shroud 0 Both of these stresses are below ables of 3 Sm = 80,000 psi and 3 Sm = 70,000 psi tively (see Figure 1). Local membrane stress intensities of 15,555 psi at Section 7-8 and 1?,575 psi at Section 17-18 are also within the allowable limits of 1.5 Sm = 40,000 psi and 1.5 Sm = 34,950 psi. Primary bending plus membrane and general primary membrane stress intensities are 26,740 psi at point b and 26,585 psi at Section a-b on the main shell which are below the allowable of 1.5 Sm = 40,000 psi and Sm = 26,700 psi. This also holds for internals with mum primary membrane stress = 7,910 psi at point.c and primary general membrane stress = 7,750 psi at Section c-d for Inconel material for which allowables are 34,950 psi and 23,300 psi respectively (see Figure 1). Subsection C of Section S3 also shows that the stilts which support the shroud will not buckle under the most critical compressive load

SUMMARY

OF STRESS ANALYSIS FOR TOP HEAD AND CYLINDRICAL SHELL In this section the maximum stress intensities in the top head and cylindrical shell due to combined loadings were computed. The loadings considered were: stud load, internal pressure, dead weight of vessel and tents, insulation weight, horizontal and vertical seismic forces, horizontal jet reactions, stabilizer rod tions, local bracket and nozzle reactions, refueling lows support loads, and the'thermal loads. The maximum stress intensities and their locations were found to be as follows: the maximum general primary membrane stress intensity occurs in that portion of the cylindrical shell which is removed from gross structural .. discontinuities. Its magnitude is 26,375 psi which is within the allowable value of 1 Sm = 26,700 psi. The maximum local membrane stress intensity of 29,610 psi occurs at 15 inches below the bottom of the shell flange hub. This stress intensity was found to be local in extent and is less than the allowable value of 1.5 Sm = 40,050 psi. The maximum range of stress intensity for primary plus secondary stresses has a magnitude of 55,320 psi which is well within the allowable of 3 Sm = 80,100 psi. The location of this stress intensity is at the top of the hub of the head flange. Subject MONTICELLO REACTOR VESSEL CO",. 9-5624 Da'e_By AEE :) 6608 Checked bv, ____ Date ____ .. R .....

• An effort was made to clear completed shell rings 18 feet diameter by 10 feet 11-1/2 inches long and weighing 140,000 pounds. Although these rings could be barged to Minneapolis, the interconnecting railroad (Minneapolis, Northfield and Southern Railway) could not move the shipment from Port Cargill to the Great Northern Cedar Lake yard interchange.

The Great Northern services the Monticello area. Overland truck handling clearance checks were also unsuccessful in finding an open route to the Great Northern Railroad: therefore, half ring sections were shipped from the shop. Figure IV-3 shows the shop assembled pieces for Monticello reactor yessel *

• A l7-foot diameter support skirt extension with leveling devices attached was shipped in one piece to the site. It joined .the stub skirt on the vessel bottom head to the long skirt constructed with the drywell. as shown in Figure IV-2. A cold forming procedure was utilized to press the bottom head, shell, and top head plates. All plate material was detailed to the maximum length and width dimensions could be delivered from eastern mills and properly handled by the fabricating facility.

The shell plates were purchased in the quenched and tempered condition and cold formed utilizing approved procedures. Before starting fabrication, all plates were inspected for size, thickness, surface condition and the mill stamps properly 411bentified. Ultrasonic testing of material was done by trained 5-3 Monticello Reactor Vessel, IV-3 and qualified personnel in accordance with Code specifications. Certified mill test reports and all quality control measures were reviewed by CB&I engineers to assure compliance with material specifications. After the plates were marked and flame cut to approximate

• size, they were pressed to shape on a 6,eee-ton hydraulic press, designed by CB&I. Any minor deviation from curvature tolerances found in checking with box templates and sweeps were corrected by sizing the plates on the press. Each plate was then marked and cut to size and edges beveled semi-automatic cutting torches. To insure proper dimensions and alignment, shop assembled weldments were fit-up and match-marked prior to shipment to: the jobsite for assembly and welding together.

The bottom head was shipped in two sections consisting of (1) the knuckle course of plates with the stub skirt attached and (2) the dollar plate assembly. The dollar plate assembly was predrilled in the shop to accommodate the 121 control rod drive sleeves. The initial holes were drilled to approximately 5 inches in diameter. These holes are large enough to accommodate a boring bar cutting assembly that was used in place for the final boring of the sleeves at the site. Because of the availability of machining equipment, this assembly and predrilling work was performed at CB&I's Greenville, plant. The final drilling of the holes was performed in place at the site. 5-4 *

• e Monticello Reactor Vessel, Page IV-4 The bottom head knuckle course shop weldment was positioned and two overlay weld metal build-ups were applied (see Figure IV-4) in the two areas where the shroud support was welded to** the bottom head. These weld build-ups were shop maChined to the contours shown in Figure IV-4. The Monticello vessel shell was made up of four rings, approximately 11 feet wide. Each ring was made from two formed plates. The half ring sections were temporarily welded and placed on a roller bed. The ring was preheated and the overlay weld metal deposited with automatic equipment similar to that shown in Figure IV-s. All shell fittings were shop installed.

Postweld e heat treatment was performed and inspection of the overlay weld deposit and insert seams was made after cool-down. The shell and head flanges were shipped directly to the site as rough machined, non-drilled, seamless forged rings from the Ladish Company plant in CUdahy, Wisconsin. The weld ends were prepared at the forge works (Ladish) for fit-up and welding to the adjacent No. 4 shell ring and top head weldment.

• This top head assembly was shipped in one piece. It was welded together from six knuckle plates and a one-piece dollar plate assembly, as shown in Figure IV-6. The internal .shroud support was completely shop fabricated, e including preliminary machining, at Greenville and shipped as an integral ring assembly to the site where it was welded in place to the bottom head. The final machining was completed after welding. 5-5 Monticello Reactor Vessel, Page IV-S The stud bolts, washers, and gaskets were shipped directly from General Electric qualified manufacturers to the jobsite storeroom.

4.3 SITE SUBASSEMBLY AND ERECTION Site subassembly of the" reactor vessel started about three months after work began on the containment vessel. Erection of the reactor bottom head followed the completion of the leak rate test of the drywell. The bottom head and stub skirt was welded to the reactor support skirt which was attached to the drywell prior to the leak rate test. Unlike the case for determining the maximum size of subassemblies at the shop, weight of the lifts or derrick capacity dictated the subassemblies that could be made at the site. The closure seams between subassembled sections were made in place. The postweld heat treatment zones were established by the location of penetrations with respect to circumferential weld joints and the adherence to safe thermal gradients through adjacent vessel materials. Methods of achieving the machined surface requirements, drilling and tapping and boring operations were developed by CB&I engineers using commercial equipment, where available, and designing and building custom-made devices, where necessary. 5-6 e e",; l Monticello Reactor Vessel, Page IV-6

• Suitable weather protection devices were provided to shelter the vessel weldments during ground assembly, welding, and postweld heat treatment.

The postweld heat treatment furnaces were also used for environmental housings for the welding and radiographic work. Figure IV-7 shows typical postweld heat of the longitudinal ring welds. Figures IV-8 and IV-9 similarly show postweld heat treatment of the bottom head and stub skirt assembly and the top head and flange assembly. Temperatures from thermocouples were permanently recorded on .a multiple point potentiometer instrument. Adequate thermocouples were used to obtain representative readings from all parts of the section being heated. The various parameters for heat treating, such as heating and cooling rate, variation of temperature during holding period, etc., were in accordance with Section III of the ASME Boiler and Pressure Vessel Code and other requirements of the General Electric specifications. 4.3.1 Site Subassembly The basic assembly yard fabrication process was performed as follows on the head and shell components: (a) shell halves joined .into rings, bottom head to skirt extension, head to flange on level work tables: (b) preheat to 300 0 F to 400 0 F and weld sections 5-7 Monticello Reactor Vessel, Page IV-7 together; i.e., four shell rings, one bottom head with skirt and one top head with flange: (c) magnetic particle check weld periodically during deposition of metal as preliminary inspection step and replace any unsound material found therein; (d) hot ultrasonic test welds before postweld heat treatment: (e) post weld heat treat at 11SOoF; (f) cool and radiograph welds; (g) ultrasonic welds again: (h) manual overlay welds: (i) postweld heat treat: (j) cool and ultrasonic overlay: (k) dye check overlay. 4.3.2 Assembly and Machining The bottom head and stub support'skirt assembly was set in place, leveled, and welded on a l7-foot diameter tubular support skirt furnished in the drywell base of the containment structure. The vessel centerline was established as a vertical line of sight using a precise jig transit instrument located below the bottom head and sighting on a target in the geometric center of the center control rod drive penetration. The leveling and plumbing procedure was repeated after placement of each of the four shell rings. The centerline for the bottom head and skirt assembly was located as shown in Figure IV-10. . The No. 1 shell ring, assembled and in the asser..bly yard, was placed as an integral ring in position atop the bottom head. The girth seam was fit, preheated and hand welded. The No. 2 ring was then placed, fit and welded. The preheat was maintained on 5-8 * *

• bottom head to No. 1 ring girth seam until the No. 1 to No. 2 girth seam was ready for postweld heat treatment.

At that time, the two rings were postweld heat treated simultaneously in the ternporarj furnace. Steps (b) through (k) used for site subassembly.(Paragraph 4.3.1) were used for assembly in place. Non-destructive testing methods in the field were the as those performed in the shop. Radiography was performed utilizing a 75 to 100 Curie Gamma source with appropriate shielding. Usage of the source was in accordance with the applicable Federal and State regulations.

• Concurrent with erection of the vessel shell, the vessel top head weldment was fit and welded to the cover flange in the yard area. After completion of all the welding, postweld heat treatment and examination steps, the top head was positioned for drilling the 5-l!4-inch diameter bolt holes, as shown in Figure IV-ll. With the cover in this same position, the grooves for the two 1!2-inch diameter stainless "0" ring gaskets were machined with the portable CB&I equipment as depicted in Figure IV-12. After the No. 1 and No. 2 girth seams were postweld heat treated, the temporary furnace was converted into an air-conditioned and ventilated work room around the bottom head and No. 1 shell ring. A temporary cover was installed above this work area so .the balance of the vessel could be erected without interfering with 5-9 Monticello Reactor Vessel, Page IV-9 the bottom head work. The holes and sleeves for the 121 6-inch control rod drive thimbles and the 40 2-inch diameter holes for the in-core flux sensors were machined utilizing precision-oored guide templates, optically aligned in a temperature"controlled housing to guide a verticle boring bar and cutter head, as shown in IV-13. These methods not only assured that the holes . were on accurate centers but that they were plumb. The vessel closure flange was drilled and tapped in the assembly yard after it was welded to the No.4 shell ring. The gasket sealing face on the vessel flange was machined in the assembly yard using the sarne equipment that was used for the top head flange. Drilling of the control rod drive sleeve holes, welding the sleeves and boring them to the final precision dimension was performed in parallel with the work on the vessel as described above. 4.3.3 Cleanina and Hydrostatic Test Upon completion of the machining work on the control rod drive sleeves, the reactor head was attached to the vessel in preparation for cleaning.

The cleaning of the interior surfaces of the vessel was done using high pressure (approximately 8000 PSI) deionized water containing SaO-ppm by of TSP. Special care was taken to thoroughly water-blast rinse all areas and crevices to 5-10 *

• Monticello Reactor Vessel, Page IV-10
• insure complete removal of the TSP solution.

The rinsing continued until the effluent conductivity was 5 micro-mho/em. Upon completion of the initial cleaning, the vessel was filled with heated deionized water and tested per the requirements of t..'1e ASME Code. Upon completion of the overload pressure test,

• the vessel head was removed and service gaskets installed.

The vessel head was then replaced and a leakage rate test was performed between the double "0" ring seals at the design pressure. Upon completion of the hydrostatic test at design pressure, the test caps were removed from the vessel and replaced wit..'1 temporary covers. The vessel was once again nigh pressure blasted .i th deionized water. After drying the interior surfaces of the vessel, the vessel was sealed to prevent entry of dirt or other foreign materials. 404 REACTOR VESSEL QUALITY CONTROL 4.4.1 Objective The quality control for the Monticello nuclear reactor was directed by a Quality Control Manager with the assistance of Quality Control Coordinators. The primary objective of this group was to coordinate CB&I's many quality connected functions into a system which assured that the reactor produced would meet the ..

• sualit y requirements and to document the fact that these quality equirements were met. 5-11 Monticello Reactor Vessel, Page IV-ll 4.4.2 Project Quality Control Oraanization Authority lines for project management and project quality control were separated by having both managers report directly to the Regional Operations Manager, who, in turn, reported to the Vice President and Manager of Operations.

Company standards and policies for quality control --or more aptly, quality assurance were" set by the Quality Control Administrator, who also reported to Vice President and Manager of Operations. The latter was on the same level as the Vice President and Manager of Welding and Inspection. The Q.C. Coordinator for manufacturing was concerned with only nuclear reactors. The Q.C. Coordinator for engineering, purchasing, and construction was concerned with this vessel from the date of contract until vessel completion.

4.4.3 Compliance

with Specifications By using check-off type records, spot Checking operations as the work progressed, and by auditing all inspections, the plant and site Q.C. Coordinators were able to assure that: 1. Approved procedures were used; 2. The approved procedures were being followed:

3. Required inspections were properly performed:

4. Inspections were witnessed by the customer's Q.C. representative; and 5. The material or part met the required level of quality before it was further processed.

Each operation or inspection was given a unique reference number so that it could be referenced to report of record. Each operation was referenced to the applicable approved procedure with special notations for witness pOints or points beyond which further progress was halted until clearance was obtained. Provision was made for sign-off by the supervisor after the operation was completed, by' the inspector after the inspection was performed, and by the Q.C. Coordinator as well as the customer's 4Itepresentative after each item or piece was reviewed and accepted. 404.4 Documents and Records In addition to the usual records required for presssure vessels built to Section III of the ASME Code, a complete thermal history of all parts and a quality control spread sheet of this vessel will be maintained for the specified time period. Written J non-destructive test reports were prepared for each radiographic, ultrasonic, magnetic particle and liquid penetrant inspection. Also, welders' performance qualification certificates and test' results' are available for review.

The analysis is concerned with Service Level A, B,*and C events, and design conditions. A fatigue analysis was also performed. This analysis of the feedwater nozzle and safe end assembly is required because of the complete redesign of the existing safe end and thermal sleeve assembly. As a consequettce of this redesign, the component's geometries will from the ones originally analyzed, thus necessitating this report. The nozzle and safe end assembly in this report are analyzed in accordance with the requirements of the ASHE Code (Reference 6.2), and the General Electric design specification (Reference 6.1).

NEBG-a07 A (6/10) 8-52 NUCLEAR ENERGY BUSINESS GROUP GENERAL. ELECTRIC 22A74S4 REV 1 SH NO. 51 4.1 Thermal Transient Analysis. The only feedwater nozzle thermal transient for the vossel operating conditions (Sorvice Levels A and B) is defined in the dosign specification (Reference 6.1). This transient is also illustrated in Figure 4.1-1 for convenience. In order to simplify the thermal analysis, the feodwater transient was idealized as two separate transients (a heatup and cooldowu). These idealized transients are illustrated in Figure 4.1-2. Notice the step change in temperatures were simulated by steep ramps. This was done to facilitate numerical convergence and rosults in slightly nonconservative strosses. For moro detailod information on the two idealized tranSients, aoe Reference 6.1. 4.i.1 Thermal Model. Th.o uisymmetric finite element model of the feedwater nozzle is shown in Figure The model is made up of 2-D axisymmetric isoparametric tomperature elements (STIF 55, Reference 6.3). A portion of the vessol wall was modeled as a disc for convenience of analysis since the effect of this approximation on the temperature solutions in the regions of interest is insignificant. The model ends (RPV, thermal sleeve, and safe end) are considered constant for all temperatures. The thermal properties used are as follows. Thermal properties are those of approximately 360°F.

The stress analysis is broken into three separate thermal stresses, mechanical load stresses, and pressure stresses. The stress intensities for these three cases are then summed up to yield the total primary plus secondary stress intensity. A fatigue analysis is then performed to obtain the fatigue usage factor for the system. 4.2.1 Selected Locations for Stress Evaluation, The sections showu in Figure 4.2.1-1 are the locations selected for stress evaluation. Finite element stresses are integrated across each section to dettrmine the equivalent membrane, bending, and peak stresses. This yas done by averaging the stress across the section and linearizing the stress distribution through the section thickness as shoYn in Figure 4.2.1-2. These calculations yere performed using an engineering aid computer program 'NONO'.

The same finite element model used for the thermal transient analysis (Figure 4.1.1-1) was also used for the thermal stress analysis. However, instead of temperature elements being used, 2-D axisymmetric isoparametric stress elements (STIF-42, Reference 6.3) were used. The modeling of the portion of the vessel wall as a disc is a conservative assumption for the thermal stress solutions since the inplane radial stiffness of a disc is higher than that of a shell. The applied boundary condition at the isolated surfaces of the vessel, safe end. and thermal sleeve is the generalized plane strain condition. The elastic properties used were considered constant for all temperatures.

The pressure stress'es were obtained using the finite element computer program ANSYS. The I.ame finite element model used for the thermal stress analysis (described in Paragraph 4.2.2 and Figure 4.1.1-1) was also used for the pressure stress analysis. The modeling of the portion. of the ves'sel "a11 as a disc is a nonconservative assumption. It is recognized that the pressure .tresses in the vessel "all regions obtained from using this model are not .trictly valid. Ho"ever, stresses in the safe end-thermal sleeve regions are valid since the effect of this modeling in these regions is insignificant. The applied boundary condition at the isolated surfaces of the safe end and thermal .leeve "as the equivalent meridional stress caused by the pressure. The vessel boundary condition was the average of the hoop and meridional stresses. 4.2.4.1 Pressure Stress Analysis Results. The pressure stresses were evaluated for the specified pressures of 1,111 psig nozzle pressure and 1,000 psig vessel pressure. The pressure membrane plus bending stresses are tabulated in Table 4.2-9. The pressure membrane'plus bending plus peak stresses are tabulated in Table 4.2-18.

At S50 o F, m carbon steel (SA-3S0 LF2) has a S of 18.6 ksi, and stainless steel (SA-351 m CP3) has a S of 16.0 ksi. In calculating 3 S , it is seen that Sections F m m through J are in excess of their limits, therefore, the simplified plastic method "i11 be used. For the simplified elastic-plastic fatigue analysis to be valid, the primary plus secondary minus thermal bending must be less than 3 S.

To calculate the alternating stress range, the following equation is used. where: It = stress concentration factor x = simplified elastic-plastic factor e SN -P+Q stress intensity F1 ""' peak stress identified by 'NONO' program The peak stress identified by the 'NONO' program is f011l1d using Tables 4.3-3 through 4.3-11. These tables contain the total surface stresses at each section. A conservative method of obtaining these peak stresses is to find the largest stress intensity range for the stresses and subtracting the P+Q stress intensity found earlier in Paragraph 4.2.S. This was followed and the results are given in Table 4.3-1. Also in Table 4.3-1 is the stress intensity range for the mechanical load case which docs not include seismic loads. These are needed to calculate the P+Q range excluding seismic, hence the alternating stress range excluding seismic is given.

Hay 7, 1981, respectively. the manufacturing deviations on the The deviations are described in detail dated April 29, 1981. July 2. 81. and 30.1 Deviations Due to DDR Number 15127. The deviations reported within DDR Number 15127 are two undersize locations on the thermal sleeve pads. The undersize amounts are two mils and four mils on the 7.812 inch diameter and the 7.625 inch diameter, respectively. It is noted. however. that the deviations are on the thermal sleeve pads. and within the previous calculations the pads are neglected conservatively. Therefore. these deviations will have no effect on the previous analysis and will not require recalculations of stresses. 30.2 Deviations Due to DDR Number 26521, 'The deviation reported in DDR Number 15140 is a tool undercut along the tapered surface the 10.84 inch diameter zone and the 12.00 inch diameter zone. However. this tool undercut was weld repaired. heat treated. and machined to original finish size. This type of repair is allowed per ASME Code, Reference 6.2. Post-weld heat treatment ensures stress relief and an acceptable metallurgical condition. The part is restored to the original specified dimensions. Therefore, these deviations will have no effect on the previous analysis and requires no recalculation of stresses. 30.3 Deviations Due to DDR Number 15139. This paragraph analyzes the effects of two manufacturing deviations on the Monticello feedwater safe end. The deviations are described in detail in DDR Number 15139. dated April 30. 1981. and illustrated on Figure 30.3-1. 30.3.1 Summary of Results.

30.3.3 Primary Plus Secondary Stress Analysis. This portion of the report discusses the detailed stress evaluation of the thermal stress, pressure stress, mechanical stress, stress ranges. and fatigue usage for selected locations of the geometry. 30.3.3.1 Thermal Stress. Sections F and G are thinner than their corresponding sections in the previous nominal calculations. The reduction in thickness for these sections is 1.65 percent and 2.3 percent (Section F and G. respectively). This small change will have no significant effect on the heat transfer coefficients and thus "ill be' directlt to the change in the biot's number. For Section F, the biot's numbers before-and after the reduction are 1.067 and 1.0494, respectively. For Section G, the biot's numbers before and after are 1.1785 and 1.1514, respectively. For both sections, the biot number is in a range that the small percentage change in it due to the thickness change will have no significant impact on the stresses in the region *. This, along with the f.act that, as the thicknesses are reduced, the relative stiffnesses are lowered, causing thermal stresses. "hich are secondary or displacement controlled stresses, to be lowered. Therefore. the stresses obtained in the previous nominal calculations "ill be conservatively used here. 30.3.3.2 Mechanical Load Stress, The stresses obtained by mechanical loading are to accollDt for the reduced thicknesses

in Paragraphs 6.1 and 6.2: (1) ,;ystcm cycles and (2) rapid cycles. Syste1:l cycles I1re thr result of operatic/nal trcnsients such as startup. illitiatioll of feedwater °flo;;, etc. being icposed on the nozzle. Rapid temperature cycling results in the unstable turbulent mixing of hot and cold water aroend the nozzle at steady state operating conditions. Since the systel:! cycle transient stresses cause the lIIaxioum thermal stresses that can be pro:'oo,ced. thro rapid cycle are not linearly additive to the ca:r.imUl:l systeo cycle stresses, ie, the stresses and fatisue daQase due to systec and rapid cycling oay be calculated independently of ecch other and the usage factors may be added. 4.2 Cycle Flit igue Analyl'..ih The c)'cIes defined in Reference 4.2 will be analyzed elsewhere.

.-.nalysis is to determine the r:tpid thereal cyclintj effects on the e and s:tfe end for the design life of the syste::l. 10.1.2 Rapid temperature cycling (on the order of v.l to 1.0 nz) occurs as a result of cold aeing injected into-a hot reactor. lbe most dO::linant cause of this cycling in the nozzle bore and on the blend radius is turbulent mixing of leaka;e flow Region A fluid (see 10.1). Rapid cycling' is caused in the absence of leakage flow by turbulent Region A fluiu c:tusing the ther::lal boundary layer around the cold ther::lal !leeve to be broxl"n up and swept against the nozzle. discharse fl"w and Region A fluid that is carried batt to causes sooe ra;!d cicling. 10.2 Procedure 10.2.1 The procedure for rapid cycle fatigue is given in Reference 6.1.
