I - Reactor Veccel - BiC Rock Point Nuclear Plant 1.' General Dencription The reactor vocac1 has an internal diameter of 106 inches and an over-all lencth including nozzica, of 380 inches. The top and bottom heads of the veccel are hemiopherical in shape. The top head is removable by meanc of a bolted flance. The scal is made by double "0" ri: go of the ucif-enerCizing type. The top head has three access porto aad two vent pcnctrationc. The bottom head has 2 coolant water inlet nozzles, -32 control rod drives, 1 liquid poicon inlet nozzle and 8 in-core monitor penetrationc. All other penetrations are made in the straight chell ncetion of the vecocl but no penetrations are made in the area opponLtc the core. The h core cupport pads are located on the bottom head and are velded -to the banc metal. The thermal chield support pads are located below the active core and are also velded to the base metal. The support pada for the stean baffic and core spray aparger are located,just above the ricer penetrations and are velded to the vessel cladding. The only other attachments to the vcscel interior are brackets which hold the inlet diffuccru in place in the bottom head. These are velded to the veccel clad < ling. Ficure 1 lirovides a pictorial arrangement of the vessel with identifi-cation of nonzlcn and supporto. The reactor vessel was fabricated by The Combuntion Encineering Company (the Vendor). 2. !!nter ial The utructural r.nterial for the vessel is as follovc: SA-302 crade B lical and chcll plate SA-336 modified !Inin clocure flanccc thia nozn.te forcinco SA-336 modified Uvz.ite c::Lennions SA-213 llozz1.c f)ance SA-182 In-coce nonzler SA-213 In-core flance SA-182 (n) All uit<_rlal uced in the fabrication of the reactor vessel was upecified by the Vendor and approved by General Electric prior to ordering. A complete set of material'opecifications ic on file at the Vendor'c plant. A typical mill specification is niven in ih911 bit 1. (b) i mplete nill reports and inspection resulto are on'ffle with the Vendoc in conpliance with Section I of the AS!E Boiler & Precoure Yeuccl code. A typical mill inspection report is civen in 8:0tibit 2. Typical Charpy tests are given in Exhibit 3 and W hibit h. P00ROR!8INAL 1

:4 (c) Specifications forl application of the stainless steel clad are given in Exhibits 5'and 6.

Inspection procedures for -liquid penetrant ~and ultrasonic testing of the stainless . stccl-clad are Given in Exhibits 7 and 8. The veld clad was applicd in accordance with Exhibits 5 and 6afterfinalstressreliefwas100%liquidpenetrantand ultrasonically tested in accordance with Exhibits 7 and 8. All cladding met the requirements of Exhibits 7 and 8 and, therefore,.no repairs to-the stainless stcol cladding vere made.

The only other cladding applied to the vessel was Inco-A cladding applied to thc cealing surfaces for the "0" rings on the vessel head flange and vessel shell flange. During vessel. fabrication radial cracking was observed in the precipitation harden cladding in both flanges prior to final machining. In both cases the material was removed, the surfaces under the cladding were examined and found to be free of any imperfections. The Inco-A cladding was. re-applied, re-heat treated for a shorter period of time and machined. The finished surfaces were thoroughly examined after machining and after hydro and found to be free of any imperfections.

(d)- Specifications.for making the main velds in the reactor vessel are given in Exhibits 9 and 10. (e) Inspection procedures for magnetic particle testing are given in. Exhibit 11. 3 Desicn (a) The -vendor performed design calculations which were reviewed and approved by the General Electric Company prior to fabrication. These calculations included the transient conditions imp'osed by the-vessel specifications as well as those required by code. The GeneralLElectric Company review uns primarily intended to assure- 'the adequacy of design methods, assumptions, etc., and did not relieve the vendor of overali design responsibility. The design conditions are summarized as follows: 1. Design pressure 1700 PSIG 0 2. Design temperature 650 7 3 Maximumloadonvesselsupports(operating) (water, core structure, fuel,etc.) 400,000 lbs. 4. Scismic loading 5% of vertical load - 5 Steam det loading 500,000 lbs. 6. Maximum loading from scram of control rod drive (per drive) 6000 lbs. 7 Maximum heat generation in vessel 2 vall opposite midplanc of reactor core 86ETU/HR/Ft' 2 ~ )

3 (b) The reactor vescel was designed and fabricated in accordance .with the requirements of the following ASME coacc: Section I - Power Boilers; Section VIII - Unfired Presourc Vessels where applicable, and code cases 1270N, 1271N, and 1273N. For areas not defined in the ASIS Codes the procedures described in the " Tentative Structural Design Basis for Reactor Pressure Vessels and Directly Associated Components", February,1959, PB-151987 U.S. Dept. of Commerce, Office of Technical Services, were used. (c) The loading basis for the vessel design accounted for internal hydrostatic pressure,' nuclear heating, steady state and trans-ient operation, static weight and piping reactions. These loadings are tabulated in Figures 2, 3 and 4. (d) The design. procedure used in the reactor vessel stress analysis for statically determinant regions was accomplished by methods deceribed in strength of materials texts. (c) Analysis of the statically indetenninate vessel reg ons was i accomplished by approximating the structure as a series of basic elements and assumin8 directions of action of the redundant shears and moments required to maintain structure continuity. Magnitudes of the redundants were detenmined by expressing the shears and moments in terms of the deflections and rotations of the elements when each element was subjected to the action of the applied loads. Total stresses at each discontinuity were calculated by classical methods. (f) The calculated stress results were within allowable values in all cases. These results are tabulated in Figures 2, 3 and 4. 4. Fabrication l The vessel, except for the control rod drive and in-core nozzles, was fabricated from rolled and formed carbon steel plate, or forgings. All stainless steel cladding (except for smaller nozzles) was applied by the weld deposit method. The smaller for6ed nozzles have stain-less steel liners installed by a brazing process prior to,attachin8 the nozzles to vessel. The brazin6 material is not exposed to primary coolant. The control rod nozzles and the in-core monitors nozzles are stainless steel forgings attached to the vessel nead by partial penetration welds in accordance with case 1273N-5 (a) The reactor vessel was fabricated and tested by the Combustion Engineering Company in their Chattanooga, Tennessee sh, ops dur-ing the period of 2-16-61 through 1-18-62. 3 l i i

r - c r a (b) All velding was performed by code qualifica velders and . to procedurea 'in conformance to ASPE Code Section IX, which were developed by Combuction Engineering and approv-ed by.the General Electric Company. A typical velding and forming droving 10 shown in Figure 5 ' ( c) Heat treatment and strees relief of the reactor vessel was in conformance with Section I.of the ASFZ Boiler and Pressure Vessel Code and all applicable code cases. Pre-heat and postheat treatment as required by the velding . procedure specifications were also performed. (d) All veld clad was ultrasonically -inopected for bonding to the base material and all clad material van dyc penetrant incpected after final heat treatment. All forcinco vere incpected by magnetic particle and ultrasonic means to accure freedom from defecto. (c) Imperfections detected in the inspection of the plates, forcinco, cladding, and veld were removed and material replaced by the vendor employing velding repair procedures which were approved by the General Electric Company. Based upon the resulto of these inspections the veccel has received an ASME code stamp and has been accepted by the General Electric Company as meeting their specifications. (f) All inspections. which were-required to meet the ASME Boiler - Code were witnecced by an inspector licensed by the National Board of Boiler and Pressure Vessel Inspectors. Continuous inspections were also performed by Combustion Engineering. personnel during fabrication. These inspections were audited by General Electric Company's Vendor Quality Assurance representatives and the important inspections, such as dye penetrant inspection of vessel cladding, verc vitnesced by a General Electric Company representative. The General Electric Company also maintained a full time representative at Combustion Engineering to follow the Conoumer's vessel during each phase of fabrication. This orrangement allowed the General Electric Company to be completely aware of the progress of the vessel'through the i. shops at all times.. The Certificate of Boiler Shop Inspection-along with Combustion Engineering Certifications are given in Exhibit 5; V (g). Figure 6 given the an-built dimensions of the reactor vessel.

\\ COMBUSTION ENGINEEil G, IIC. CHATTANOOGA, Tt,t!NESSEE M&P SPEC. NO.: 2.h.3.1(a) DATE: April 27, 1960 SHEET: 1 of h PROCESS SPECIFICATION FOR LIQUID PENETRANT TESTING

1.0 Scope

1.1 This Process Specification provides for the method and standard of acceptance for liquid penetrant testing of nuclear components. 1.2 The penetrant test method is used for detecting the presence of discontinuities in ferrous and nenferrous materials. Discontinuities not open to the surface will not appear since penetration into an open defect is necessary before this method will work. For this reason its use is generally limited to the non. ferrous metals and nonmagnetic steels. Inspection methods covered by this standard shall be of the following types. Dje penetrant (water washable) Type I Dye penetrant (nonwater washable) Type II Flourescent penetrant (integral emulsification) Type III Flourescent penetrant (post emulsification) Type IV 2.0 Surface Preparation: 2.1 General - Surface of welds, castings, or wrought metals may be inspected without surface preparation or conditioning except as required to remove scale, slag, and adhering or imbedded sand. Blasting shall be accomplished by using angular or subangular cutting type sand, silicon carbide, or alumina grit. When blast peening, using steel shot, etc. is necessary before the penetrant inspection test, the blast peening shall be followed by blast-ing with angular or subangular cutting type sand, silicon carbide, or alumina grit, or by chemical cleaning. "As welded" surfaces, following the renoval of slag, shall be considere'd suitable for liquid penetrant inspection without any grinding, provided the weld contour blends into the base metal without undercutting, and the contour and surface finish of the veld is in accordance with applicable specifications. 3.0 Test Procedures: 31 Pretest Cleanliness - All materials being tested shall be cleaned by hot running water, by dipping in a solvent, or by swabbing with a clean lint-free cloth saturated with acetone. 32 The temperature of the penetrant and the part to be inspected shall be maintained between 50*F and 125'F. When inspection is necessary under con-ditions where the temperature of the penetrant and the inspection surface is outside the 50*F to 125*F range, the temperature shall be' adjusted to bring them within this range. Due to the flammable nature of liquid penetrant inspection materials, the use of an open flame for heat purposes is prohibited.

COMBUSTION ENGINEERING, INC. CHATTANOOGA, TENNESSEE M&P SPEC. NO. : 2.h.3 1(a) DATE: April 27, 1960 SHEET: 2 of h 33 The surface to be tested shall be thoroughly coated with penetrant by spraying, brushing, or immersion. The surface shall be kept vetted for the minimum time specified for the method employed: Penetrant Penetration Time All Applications Type I 30 Minutes Type II 10 Minutes Type III 30 Minutes Type IV 10 Minutes 3.h The Type IV emulsifier shall be applied either by dipping or spraying the .part. It should not be applied by means of a brush since stroking with a brush may renove the penetrant from shallow or scratch like discontinuities. After a suitable penetration time and emulsification period the surface film of the penetrant and emulsifier shall be removed from the part by employing a hot water spray not exceeding 120*F. Washing shall be checked under a black light to insure complete cleaning of all surfaces. Alterna-tively, the penetrant may be removed by use of the cleaner recommended by the manufacturer of the penetrant. 3.5 The penetrant of Types I and III shall be removed fron all surfaces by swabbing with a clean lint-free cloth saturated with clear water or by spraying with water at moderate pressure. Alternatively the penetrant may be removed by wiping the excess penetrant from the test surface with a clean dry lint-free cloth followed by wiping the partially cleaned surface with an alcohol dampened clean cloth until all traces of the penetrant have been removed. 3.6 The Type II penetrant shall be removed from all test surfaces by wiping with clean lint-free dry rags using the cleaner recommended by the manufacturer. Excessive application of the cleaner shall be avoided to prevent the possi-bility of removing the penetrant from discontinuities, causing a decrease in the sensitivity of the test. It is best to slightly dampen a cloth with cleaner and wipe the part rather than flush the part with liquid cleaner. 37 The drying of test surfaces shall be acconplished by using circulating air, blotting with paper towels or clean lint-free cloth or normal evaportation. It is important that in the drying operation no contamination material such as oil from air nozzles or lint from rags be introduced into the sur-face which may cause misinterpretation during the inspection operation. 3.8 Dry developing powders shall be uniformly applied to surfaces resulting in a dust like appearance. Dry developers require a dry surface before application, or it will mat heavily on the wet surfaces. A short time shall be allowed for development of indications after the developing powder is applied. This time shall be about half as long as the time allowed for penetration. l

CHATTANOOGA, TENNESSEE M&P SPEC NO.: 2.h.3.1(a) DATE: Anril 27, 1960 SHEEI: 1 of b PROCESS SPECIFICATION FOR LIQUID PENETRANT TESTING

1.0 Scope

1.1 This Process Specification provides for the method and standard of acceptankd for liquid penetrant testing of nuclear components. 1.2 The penetrant test method is used for detecting the presence of discontinuittes in ferrous and nonferrous materials. Discontinuities not open to the surfake will not appear since penetration into an open defect is necessary before this method will work. For this reason its use is generally limited to the non-ferrous metals and nonmagnetic steels. Inspection methods covered by this standard shall be of the following types. Dye penetrant (water washable) Type I Dye penetrant (nonwater washable) Type II Flourescent penetrant (integral emulsification) Type III Flourescent penetrant (post emulsification) Type IV 2.0 Surface Preparation: 2.1 General - Surface of welds, castings, or wrought metals may be inspected without surface preparation or conditioning except as required to remove scale, slag, and adhering or 12nbedded sand. Blasting shall be accomplished by using angular or subangular cutting type sand, silicon carbide, or alumina grit. When blast peening, using steel shot, etc. is necessary before the penetrant inspection test, the blast peening shall be followed by blast-ing with angular or subangular cutting type sand,. silicon carbide, or alumins grit, or by chemical cleaning. "As welded" surfaces, following the renoval of slag, shall be considered suitable for liquid penetrant inspection without any grinding, provided the weld contour blends into the base metal without undercutting, and the contour and surface finish of the weld is in accordance with applicable specifications. 3.0 Test Procedures: 3.1 Pretest Cleanliness - All materials being tested shall be cleaned by hot running water, by dipping in a solvent, or by swabbing with a clean lint-free cloth saturated with acetone. 3.2 The temperature of the penetrant and the part to be inspected shall be maintained between 50*F and 125'F. When inspection is necessary under con-ditions where the temperature of the penetrant and the inspection surface is outside the 50*F to 125'F range, the temperature shall be adjusted to bring them within this range. Due to the flamnable nature of liquid penetrant inspection materials, the use of an open flame for heat purposes is prohibited.

.o. COMBUSTION EEINEERXHG, I!!C. CHAIIANordA, TE!NESSEE MbP SPEC. NO.: 2.h.3,1L) PATE: Apr11 El, H60 SHEET: 2 of h J.3 The surface.to be tested shall be thoroughly coated with penetre.it by spr aying, brushing, or immersion. The surface shall be kept wetted for tha minimum time specified for the method employed: Penetrant Penetration Time All Applications Type J 30 Minutes Type II 10 Minutes Type III 30 Minutes Type IV 10 Minutes 3.h Tne Type IV emulsifier shall be applied either by dipping or spraying the part. It should not be applied by means of a brush since stroking with a brush may remove the penetrant from shallow or scratch like discontinuitica. After a suitable penetration time and emulsification period the surface film of the penetrant and emulsifier shall be removed from the part by employing a hot water spray not exceeding 120* F. Washing shall be checked under a black light to insure complete cleaning of all surfaces. Alterna-tively, the penetrant may be removed by use of the cleaner recomnended by the manufacturer of the penetrant. 3.$ The penetrant of Types I and III shall be removed from all surfaces by swabbing with a clean lint-free cloth saturated with clear water or by spraying with water at moderate pressure. Alternatively the penetrant may be removed by viping the excess penetrant from the test surface with a clean dry lint-free cloth followed by wiping the partially cleaned surface with an alcohol dampened clean cloth until all traces of the penetrant ha ve been removed. 3,6 The Type II penetrant shall be removed from all test surfaces by wiping with clean lint-free dry rags using the cleaner recommended by the manufacturer. F.xcessive application of the cleaner chall be avoiced to prevent the posaj-bility of removing the penetrant from discontinuities, causing a decrease in the sensitivity of the test. It is best to slightly dampen a cloth with cleaner and wipe the part rather than flush the part with liquid cleaner. 3.7 The drying of test surfaces shall be accomplished by using circulating air, blotting with paper towels or clean lint-free cloth or normal evaportation. It is 12nportant that in the drying operation no contamination material such as oil from air nozzles or lint from rags be introduced into the sur-face which may cause misbiterpretation during the inspection operation. 3.S Dry developing powders shall be uniformly applied to surfaces resulting in a dust like appearance. Dry developers require a dry surface before application, or it will mat heavily on the wet surfaces. A short time l shall be allowed for development of indications after the developing powder is applied. This time shall be about half as long as the time allowed for pe.?tration. o

COMBUSTION ENGINEERING, INC. CHATTANOOGA, TENNESSEE l MkP SPE C. NO. : 2.b.3.1(a) i DATE: April 27, 1960 SHEET: 3 of h 3.9 Wet type developers shall be uniformly applied to surfaces by dipping, spraying or brushing. When using liquid type developers it is necessary that they continually agitated in order to prevent settling of solid particles dispersed in the liquid. Pools of wet developer in cavities on the inspection surface shall be avoided since these pools will dry to an excessively heavy coating in 5.ch areas resulting in the masking of indications. h.0 Test Results: h.1 General - All indications revealed by the penetrant are not necessarily defects since nonrelevant indications are frequently encountered in liquid penetrant inspection, generally due to failure to completely remove the excess penetrant from the surface being examined. At least 10 per cent of such indications shall be removed to determine if defects are present. The absence of indications upon re-examination by liquid penetrant shall be considered to prove the indications non-revelant in respect to actual defects. h.2 Acceptance Standards for Welds - h.2.1 Examination of welds by liquid penetrant methods shall be made over en area including the weld and base metal extending for at least h" on each side of the weld. h.2.2 Surfaces examined by fluid penetrant methods shall be free of laps, fissures, cracks or other linear defects. h.2 3 In any 6" length of weld and adjacent base metal examined, there shall be no indications greater than 1/32" diameter, as revealed by fluorescent penetrant examination, or 1/16" diameter as revealed by the dry penetrant. Nor shall there be more than six (6) indications whose sum of diameters is greater than three (3) times the maximwm diameter specified herein. Any 6" length of weld shall be interpreted to denote the 6" length selected in the least favorable location with respect to the discontinuities disclosed by the inspection test. Indications of pinpoint porosity may be permitted if well dispersed, and if the pattern formed does not indicate that they are linearly disposed so as to promote formation of a crack or other continuous defect under stress. In linearly disposed porosity the average of the center-to-center distances between any one indication ar.d the two adjacent indications shall not be lessthan3/16". h.3 Acceptance Standards For Weld Deposited Cladding - h.3.1 Examination of weld deposited cladding by liquid penetrant. methods shall be made over a h" dianeter circular area. In lieu of ha diameter circular area, a 3}" square area may be used.

Nor shall there be more than six (6) indications whose sum of diameters is greater than three (3) times the maximum diameter specified herein. Any h" diameter circular area of cladding shall be interpreted to denote the h" diameter circular area selected in the least favorable location with respect to the discontinuities disclooed by the inspection test. Indications of pinpoint porocity may be permitted if well disposed and if the pattern formed does not indicate that they are linearly disposed so as to promote formation of a crack or other continuous defect under stress. In linearly disposed porosity the average of the center-to-center distances between any one indication and the two adjacent indications shall not be less than 3/16". h.h Defect Removal - h.h.1 Only such defects need be renoved and repaired as to render the weld acceptable to the requirements of this standard. Defective areas may be ropaired by welding performed in accordance with an approved welding procedure. The a reas containing defects shall be ground out to remove the defects. The ground out areas shall be reinopected to ascertain the complete removal of the defect. Completed repairs shall be reinspected by the method originally used.

5.0 Exception

5.1 The acceptance criteria of Paragraph h.3 shall not apply where the weld has been subjected to radiographic exanination. Acceptability of radio-graphed welds shall be based on their radiographs compared to the applicable standard of acceptance. Defects defined in Paragraph h.2 shall be removed or repaired regardless of radiographic test results.

All pipe 2-1/2" and larger is butt welded by the Tungsten inert gas process for at least the first pass, using an internal inert gas purge. Subsequent passes are manual metallic arc or automatic submerged arc. Consumable in-2 sert rings are optional for shop velds but are used for all field welds on the above systems. I Branch connections 2" and under are either butt welded as above or socket welded, using k000 psig rating for the mai:. 6 team and feedwater connections and 3000 psig rating fo. main condensate connections. Materials, design ratings, and fabricating procedures for feedwater piping between the steam drum and the second valve from the drum and main steam piping between the steam . drum and the first valve conform to the requirements of the ASME Boiler and Pressure Vescel Code.

7-steam,.feedwater, and condensate piping conforms to the require-ments of the ASA Code for Pressure Piping, Section I. All welds on the carbon steel pipe with a thickness equal to or. greater than 3/4" are stress relieved at 1150 F to 1250 F for one hour per inch of thickness. Preheating of carbon steel pipe to be. welded is required -when the wall.is greater-than 1 inch or the ambient temperature is 32 F or lower. d) Inspections Specified All. butt welds in piping fabricated in accordance with Section 1 of the ASME Boiler and Pressure Vessel Code 'are 100%radiographed. The standards of acceptability are in accordance with the ASMB Boiler and Pressure Vessel Code, Section I, Paragraph 102. Hydrostatic testing of shop fabricated piping assemblies are not required; however, the fabricated assemblies and the field welds are subject to pressure tests after erection in accordance with the ASME Boiler and Pressure Vessel Code, Section I, and the ASA Code for Pressure Piping, Section I. Inspection during fabrication and erection has been made to insure that adequate standards of workmanship and materials are maintained. 3) Inspection Results Inspection on shop fabricated assemblies and welding has been performed by.the Hartford Steam Boiler and Inspection Company. The manufacturer's Partial Deta Reports (Form P 14) have been certified for all shop fabricated pipe falling under. ASME Code Procedures and have insurance company serial nurfoers: HSB-P-10993, thru HSB-P-10999, HSB-P-11000, and HSB-P-11001. These reports were made after all.necessary x-rays and visual inspection were complete. The finished erected main steam, feedwater, and maiu con-densate systems will be subjected to a hydrotest at pressures as follows : Main Steam - st'eam drum to.first valve.......... 2415 psiE .First valve to turbine and condenser....... 2160 psig Feedwater - stean drum to second va.c........... 2415 ps ig Second valve to feed pumps................. 2160,psig ' Condensate....................................... 300 psis 2'- a}}
