i j 5.3.1.2 Special Processes Used for Manufacturing and Fabrication The RPV is primarily constructed from low-alloy, high strength l

steel plate and forgings. Plates are ordered to ASME SA 533 Grade B, Class 1, and forgings to ASME SA 508, Class 2. These materials are melted to fine grain practice and are supplied in the quenched and tempered condition. Further~ restrictions include a requirement for vacuum degassing to lower the hydrogen level and improve the cleanliness of the low-alloy steels.

Studs, nuts, and washers for the main closure flange are ordered l to ASME SA 540, Grade B 23, or Grade B 24. Welding electrodes i are low hydrogen type ordered to ASME SFA 5.5.

All plate, forgings, and bolting are 100% ultrasonically tested i

and surface examined by magnetic particle methods or liquid j penetrant methods in accordance with ASME Code,Section III standards. Fracture toughness properties are also measured and controlled in accordance with Section III requirements.

l All fabrication of the RPV is performed in accordance with General Electric (GE) approved drawings, fabrication procedures, j and test procedures. The shells and vessel heads are made from formed plates, and the flanges and nozzles from forgings.

Welding performed to join these vessel components is in

(

accordance with procedures qualified in accordance with ASME Code,Section III and II requirements. Weld test samples are required for each procedure for major vessel full penetration welds. Tensile and impact tests are performed to determine the properties of the base metal, heat affected zone, and weld metal.

submerged arc and manual stick electrode welding processes are employed. Electroslag welding is not permitted. Preheat and interpass temperatures employed for velding of low-alloy steel meet or exceed the requirements of ASME Code,Section III.

Post-veld heat treatment at 11000F minimum is applied to all low-alloy steel welds.

i Radiographic examination is performed on all pressure-containing l welds in accordance with requirements of ASME Code,Section III, l Paragraph N-624 including Summer 1975 Addenda. In addition, all l welds are given a supplemental ultrasonic examination.

5.3.1.5 Fracture Touchness, This section is supplemented by Section 5.3.1.7 and 5.3.1.8 in discussing the compliance to the intent of 10CFR50, Appendix G.

5.3.1.5.1 Assessment of 10 CFR Part 50, Appendix G l A major condition necessary for full compliance to Appendix G is satisfaction of the requirements of the Summer 1972 Addenda to Section III of the ASME Code. This is not possible with components that were purchased to earlier code requirements. For the extent of compliance see Tables 5.3-1a and 5.3-2a.

Ferritic materials complying with 10 CFR, Part 50, Appendiz G aust have both drop weight tests and Charpy Y-notch (CVN) tests with the CYN specimens oriented transverse to the maximum material working direction to establish the RT yrg . The CYN tests must be evaluated against both an absorbed energy and a lateral expansion criteria. The maximum acceptable RTurt must be

~

determined in accordance with the analytical procedures of AS5E Code Section III, Appendix G. Appendix G of 10 CFR, Part 50 requires a miniana of 75 ft-lb upper shelf CYN energy for beltline material. It also requires at least 45 ft-lb CYN energy and 25 mils lateral expansion for bolting material at the lower of the preload or lowest service temperature.

By comparison, materials for the Limerick Units 1 and 2 reactor vessels are qualified by drop weight tests and/or in most cases l longitudinally oriented CYN tests (both not required) , confirming

~

that the material nil-ductility transition temperature (NDTT)  :

longitudinal is at least 600F below the lowest service I temperature. When the CYN test was applied, a 30 ft-lb energy level was used in defining the NDTT. There was no upper shelf CYN energy requirement on the Limerick Units 1 and 2 beltline material. The bolting material was qualified to a 30 ft-lb CVN energy requirement at 600F below the minimum preload temperature.

o

' I To determine operating limits in accordance with 10 CFR, Part 50, Appendix G, estimates of the beltline material RT uro and the highest RT ,,,of all other material were made, as explained in 5.3-3 3DaRg pg,g

l LGS FSAR Section 5.3.1.5.3. The method for developing these operating limits is also described therein.

5.3.1.5.2 Method of Compliance The method of compliance is based on the last paragraph on p.

19013 of the July 17, 1973 Federal Register. The intent of the proposed special method of compliance with Appendix G for this vessel is to provide operating limitations on pressure and temperature based on fracture toughness. These operating limits ensure that a margin of safety against a nonductile failure of l this vessel is very nearly the same as a vessel built to the Summer 1972 Addenda.

l The specific temperature limits for operation when the core is critical are based on a proposed modification to 10 CFR, Part 50, Appendix G, Paragraph IV, A.2.C. The proposed modification, its justification and the results of an NRC review are given in GE Licensing Topical Report NEDo-21778-A.

LGS FSAR A minimum boltup and pressurization temperature of 800F is called for, which is at least 600F above the flange region RTuoT for Limerick 1. This exceeds the minimus BTgor temperature required by ASME Code Section.III, Paragraph G-222 (c) , Sunner 1976 and later editions. A flange region flaw size less than 0.24 inch critical flaw depth can be detected at the outside surface of the flange to shell and head junctions where stresses due to boltup are most limiting.

l LGS FSAR 5.3.1.5.3 sethods of obtaining operating Limits Based on l Fracture Toughness operating limits that define minimum metal temperatures versus reactor pressure during normal heatup and cooldown, and during inservice hydrostatic testing, are established using the methods of Appendix G of Section III of the ASME BSPV Code, 1971 Edition including the Summer 1972 Addenda. The results are shown in Figure 5.3-4 (Linerick Unit 1) and 5.3-5 (Limerick Unit 2) .

Estimated RTggy values and temperature limits are given in this section for the limiting locations in the reactor vessel.

All the vessel shell and head areas remote from discontinuities I were evaluated and the operating limit curves are based on the Limiting location. The boltup limits for the flange and adjacent l

l shell regions are based on a minimum metal temperature of RT woT +

l 60*F. The maximum throughwall temperature gradient from continuous heating and cooling at 1000F per hour was considered.

The safety factors applied were as specified in ASME Code Appendix G and GE BWR Licensing Topical Report NEDo-21778-A.

For the purpose of setting these operating limits the reference temperature, RTggy, is determined from the toughness test data taken in accordance with requirements of the Code to which the vessels are designed and manufactured. These toughness test data, CYN and/or dropweight NDT are analyzed to permit compliance with the intent of 10 CFR, Part 50, Appendix G. Because all toughness testing needed for strict compliance with Appendix G was not required at the time of vessel procurement some toughness results are not available. For example, longitudinal CYN's, instead of transverse, were tested, usually at a single test temperature of +100F or +400F, for absorbed energy. Also, at the time, either CYN or dropweight testing was permitted; therefore, in many cases both tests were not performed as is currently required. To substantiate the design adequacy, toughness property correlations are derived for the vessel materials in order to give a conservative estimate of RTg wr , compliant with '-

the intent of Appendix G criteria.

These toughness correlations vary, depending on the specific material analyzed, and are derived from the results of WRC Bulletin 217, " Properties of Heavy Section Nuclear Reactor

steels," and from toughness data from the Limerick Unit 1 and 2

, vessels and other reactors. In the case of vessel plate material (SA-533 Grade B, Class 1) , the predicted limiting toughness l property is either NDT or transverse CYN 50 ft-lb temperature minus 60*F. NDT values are available for all beltline and some other Limerick 1 and 2 vessel plates. Where NDT results are missing, NDT is estimated as the longitudinal CYN 35 ft-lb transition temperature. The transverse CYN 50 ft-lb transition temperature is estimated from longitudinal CYN data in the 5.3-5 DRAFT

- ._-. . - - - - =_ _. . - . .

LGS FSAR following manner. The lowest longitudinal CVN ft-lb value is adjusted to derive a longitudinal CYN 50 ft-lb transition temperature by adding 20F per ft-lb to the test temperature. If 1 the actual data equals or exceeds 50 f t-lb, the test temperature ,

is used. Once the longitudinal 50 ft-lb temperature is derived, I an additional 300F is added to account for orientation effects j and to estimate the transverse CYN 50 ft-lb temperature minus 600F, estimated in the preceding manner.

For f orgings (SA-500 Class 2) , the predicted limiting property is the same as for vessel plates. CYN and dropweight values are l available for the vessel flange, closure head flange, and feedwater nozzle materials for Limerick Units 1 and 2. RT ggy is estimated in 'the same way as for vessel plate.

For the vessel weld metal the predicted limiting property is the CYN'50 ft-lb transition temperature minus 600F, as the NDT values are --500F or lower for these materials. This temperature is deri7ed in the same way as for the vessel plate material, except the 300F addition for orientation effects is omitted since there is no principal working direction. When NDT values are l available, they are also considered and the RTarr is taken as the i higher of NDT or the 50 ft-lb temperature minus 600F. When NDT is not available, the RTy g7 shall not be less than -500F, since lower values are not supported by the correlation data.

For vessel wold heat affected zone (HAZ) material the RTwar is assumed the same as for the base material, since ASME Code weld procedure qualification test requirements and post-veld heat 1,

treatment indicates this assumption is valid.

Closure bolting material (SA-540 Grade B24) toughness test requirements.for Linerick Units 1 and 2 are for 30 ft-lb at 600F

.below the boltup temperature. Current Appendix G requirements are l

, for 45 ft-lb and 25 mils lateral expansion (MLE) at the preload or lowest service tenperature, including boltup. All.Limeriet unit 1 closure stud materials meet current requirements nt +100F.

All but one heat, for which records were not available, of the Limerick Unit 2 closure stud materials meet current requirements at +100F. The'purchuse requirement for Limerick Unit 2 closura l stud material waa for 30 ft-lb at +100F, and no deviation is reported. Thus, 600F is added to the specified test temperature for Limerick Unit 2 to derive the boltup temperature.

Using this general appro.ach, an initial RTuor of 200F is established for the core beltline region for Limerick Unit 1 and later for Limorick Unit 2. l

' The effect of the main closure finnge discontinuity is considered by.. adding 600F and 900F to the RTwdr to establish the minimum

, temperature for boltup and pressurization respectively. The minimum boltup temperature of 800F for Limerick Unit T, which is l

DRMT

i 9

e

, LGS FSAR shown in Figure 5.3-4 is based on an initial RTwar of +200F for the shell plate which connects to the closure flange. The minimum boltup temperature of +700F (preliminary) for Limerick l Unit 2, which is shown in Figure 5.3-5, is based on an initial RT ggy ,

of +100F for the closure flange forgings.

Because the toughness testing in strict compliance with 10CFR50 Appendix G was not required at the time of vessel procurement, the effect of the reactor vessel discontinuities is considered by adjusting the results of a BWR/6 reactor discontinuity analysis to the Limerick reactors. The BWR6 analysis performed in accordance with 10CFR50 Appendix G includes the margin of safety implicit in the Appendix G requirement. The adjustment is made by increasing the miniaua temperatures required by the difference between the Limerick and BUR /6 feedwater nozzle forging RTwar's.

The adjustment is based on an RTnpr of 400F for Limerick Unit 1 and an RT ggy of later for Limerick Unit 2.

l t The reactor vessel closure studs have a minimum Charpy impact l energy of 48 ft-lb and a 27 HLE at 100F for Limerick Unit 1. The l

studs for Limerick Unit 2 have a specified Charpy energy of 30 ft-lb at 100F. The lowest service temperature for boltup of Limerick Unit 2 is taken to be 600F above the later value and is later. Charpy test results are discussed in sections 5.3.1.7 and 5.3.1.8.

5.3.1.6 Material surveillance 5.3.1.6.1 Compliance with " Reactor Vessel Baterial Surveillance Program Requirements" The materials surveillance program monitors changes in the

~

fracture toughness properties of ferritic materials in the reactor vessel beltline region resulting from their exposure to neutron irradiation and thermal environment.

~

saterials for the program are selected to represent materials used in the reactor beltline region. The specimens are manufactured from a plate actually used in the beltline region,

and a weld typical of those in the beltline region, and thus l represent base metal, weld metal, an? the transition zone between base metal and weld. The plate and t Li are heat treated in a manner that simulates the actual 4'at 'reatment performed on the l core region shell plates of tha 1syph ed vessel.

Further details of the vessel surveillance programs are provided in section 5.3.1.9.

The surveillance program includes three capsule holders per reactor vessel.

I A set of out-of-reactor baseline CYN specimens is provided with '

h - ,;G the surveillance test specimens.

charpy impact specimens for the reactor vessel surveillance programs are of the longitudinal orientation consistent with the ASME requirements prior to the issue of the 1972 Addenda and ASTH

! E185-73. Based on GE experience, the amount of shift measured by these irradiated longitudinal test specimens is essentially the same as the shift in an equivalent transverse specimen.

'[ For Limerick Units 1 and 2, each set of surveillance specimens is s

loaded in six small capsules rather than one large capsule.

,, Therefore, each capsule holder which contains all six small

>~ capsules can be considered to be the same as one surveillance capsule as defined in 10 CFR, Part 50, Appendix H. Three capsule holders are included in each reactor vessel. Since the predicted adjusted reference temperature of the boltline region is less l s

.than 100*F at end-of-life and the calculated peak neutron fluence is less than 5 x 1088 n/cm2, the'use of three capsule holders neets the requirements of 10 CFR, Part 50, Appendix H, and ASTH E185-73.

The withd'r 'awal schedule of the three sets of specimens in the reactor is. planned as follows:

a ." The first set is withdrawn when its exposure corresponds to the calculated exposure of the reactor vessel wall at 25% of the reactor design life.

1

b. The second set is withdrawn when its exposure corresponds to the calculated exposure of the reactor vessel vall at 75g of'the reactor design life.

c. The third set is a spare to be withdrawn based on previously developed data.

The predicted peak EOL fluence at the 1/4 depth of the vessel beltline is 1.1 x loss n/cm2 after 40 years of service. Transition temperature changes; and variations in upper shelf energy were calculated in accordance with the rules of Regulatory Guide 1.99. Reference temperatures were established in accordance with 10CFR50 Appendix G and NB-2330 of the ASME Code.

5.3.1.6.4 Positioning of Surveillance Capsules and Method of l Attachment Surveillance specimen capsules are located at three azimuths at a common elevation in the core beltline region. The sealed capsules are not attached to the vessel but are in welded capsule holders. The capsule holders are mechanically retained by capsule holder brackets welded to the vessel cladding as shown in Figure 5.3-3.

There are two categories of beltline welds identified: " shop" welds and " field" welds. The shop welds represent vessel vertical seams which were made prior to shipment of pre-assembled ring segments to the Limerick 1

5.3.1.7.2 Effects of Irradiation Copper and phosphorus values used to estimate the effects of irradiation on toughness are presented in Table 5.3-5.

Estimated starting (i.e., unirradiated) HTwor values for the beltline plate and weld materials are presented in Table 5.3-5.

These values were calculated using the data in Tables 5.3-3 and 5.3-4 in accordance with ASME Code Section III, NB2300.

l 5.3.1.7.3 Upper Shelf Toughness Testing Charpy V-notch upper shelf toughness testing was not required when the Limerick 1 vessel was manufactured. Appendix G of 10CFR50 requires a minimum of 70 f t-lb transverse upper shelf CYN energy for beltline material. Branch Technical Position HTEB 5-2 indicates that 70 ft-lbs is adequate for fluence levels less than 1 x 102* n/cma, All of the Limerick 1 beltline plates were CYN impact tested as longitudinal specimens at only one temperature, +400F. The lowest CVN value obtained for beltline plate was 45 ft-lb with l 50% shear, and the highest was 104 ft-lb with 70s shear. The 50%

~

shear value suggests there is a considerable margik remaining j before the upper shelf (i.e. , 100% shear) level is reached.

Table 5.3-6 summarizes the test certificate for a representative Limerick 1 beltline plate. Similar data are also documented for all other plates. Supporting data from representative plate materials in other BWR plants are provided in Table 5.3-7.

compatibility of the supporting data from other BWRs, Plants A through E, with respect to Limerick is based on criteria such as similarity in material, fabrication, vendor source, welding procedure, etc. All listed plate materials were produced by Luken's Steel Co. These data show that plate with as low as 36 ft-lb (Plant E, heat no. C9570-1) of absorbed energy at +400F can have longitudinal upper shelf energies in excess of 100 ft-lbs.

ETEB 5-2 states that longitudinal values should be reduced to 65%

l of the test value in order to estimate transverse upper shelf.

50 = .65 (L) - (.14) [ .6 5 (L) ] (where L is unirradiated longitudinal upper shelf value) l This equation predicts a minimum required unirradiated longitudinal upper shelf toughness requirement of 89 ft-lbs.

Table 5.3-7 indicates that toughness in excess of 89 ft-lbs is to be expected for longitudinal upper shelf of this material.

Although upper shelf testing was not required for the beltline velds, Table 5.3-4 shows that the majority of the weld materials, both field and shop, meet the 75 ft-lb sinimus upper shelf requirement. Of those heats where CVN toughness tests were run at only one temperature (usually +100F) and the minimum requirement was not net, there is considerable margin for improved properties at higher test temperatures (e.g. , heat #/ lots 07L8 57/B101A271, 28 ft-lbs and 20% shear & +100F) . Further upper shelf toughness data for similar velds, made by the same vendor as Limerick 1, are given in Table 5.3-8. Tables 5.3-9 and 5.3-10 present the typical weld procedures for this data base; these tables summarize surveillance program weld procedures (including that for Limerick 1) and other vessel material data representative of the Limerick 1 beltline velds. These data are 1 in excess of 75 ft-lbs at the upper shelf. Furthermore, due to i the relatively low quantities of Cu in the Limerick i beltline

, welds, no significant decrease in upper shelf toughness due to irradiation is predicted.

The base plate and weld materials used to fabricate the surveillance test plate are identified in Table 5.3-5. The base metal from a core beltline plate heat No. C7689-1 was used for surveillance test material. With respect to initial RTggy and percent of copper by weight, this material is considered equivalent to other beltline plates and its utilization for test plate fabrication is in compliance with current recommendations for selection of surveillance materials. The test plate weld, like the core beltline vertical weld seams, was made using both Shielded Metal Arc (SHAW) and Submerged Arc (SAW) welding processes. The test plate weld procedure is presented in Table 5.3-10. For each of the two welding processes, only one heat of weld material was used. The SAW material heat / flux No.

IP4218/3929-989, which was also used for beltline seams BE, BA, j and BB (Figure 5.3-7) , is considered suitable for surveillance l nonitoring because it represents the most limiting SAW material l in terms of shif t and predicted end-of-lifS RTwgr . The SHAW ,

surveillance material was not used for production beltline welds however, the weight percentages of copper and phosphorus which it 1 contains (.09 Cu and .018 P) are generally graater than those for actual beltline material. Horeover, the unirradiated RTggr Of this material is equivalent to the initial RT,mr of the beltline weld materials. The CBSI weld procedure for test plate  ;

fabrication involves utilizing stick electrode to fuse back-up bars and completing the major volume of the weld with SAW. This includes backgouging of the back-up bar to complete the back side of the weld. Therefore, the test plate weld metal is essentially submerged-arc-welded material. Table 5.3-5 indicates that all beltline materials, both plate and weld, are highly resistant to irradiated degradation of notch toughness.

Table 5.3-16 lists the actual number of specimens and their l orientations in each surveillance capsule (including tensile l specimens). The number and orientation of the Charby impact specimens are consistent with the ASME requirements prior to the issuance of the Summer 1972 Addenda and ASSE 185-73.

Prior surveillance experience indicates the amount of radiation-induced shift in properties measured by longitudinally oriented specimens is applicable to equivalent transverse-oriented specimens. Therefore, the shift when determined can be used for the transverse RTwer values for the beltline materials.

Referring to Table 5.3-16, the longitudinal orientation of the base metal HAZ specimens are such that they simulate beltline vertical seams in this manner.

5.3.1.10 Reactor Yessel Fasteners l

The reactor vessel closure head (flange) is fastened to the reactor vessel shell flange by multiple sets of threaded studs

(

and nuts. The lower end of each stud is installed in a threaded hole in its vessel shell flange. A nut and washer are installed

.on the upper end of each stud. The proper amount of preload can be applied to the studs by a sequential tensioning using hydraulic tensioners. The design and analysis of this area of the vessel is in full compliance with all Section III Class I Code requirements. The material for studs, nuts, and washers is SA-540 Grade B23 or B24. The maximum reported ultimate tensile stress for the bolting material is 164,000 psi which is less than l the 170,000 psi limitation in Regulatory Guide 1.65. Also, the Charpy impact test recommendations of Paragraph IV.A.4 of Appendix G to 10 CFR, Part 50 were not specified in the vessel order since the order was placed prior to issuance of Appendix G to 10 CFR 50. However, impact data from the certified materials report shows that all bolting materials meet the Appendix G impact properties.

A phosphate coating is applied to threaded areas of studs and nuts and bearing areas of nuts and washers to act as a rust inhibitor and to assist in retaining lubricant on these surfaces.

i The fracture toughness analysis for system pressure tests with fuel in the reactor yields the curves labeled A shown in Figures 5.3-4 and 5.3-5. The curves labeled " core beltline" are based on an initial HTudr of 200F for Limerick Unit 1 and later for Limerick Unit 2. The predicted shift in the RTwov from Figure 5.3-6, based on the neutron fluence at 1/4 of the vessel wall I thickness, must be added to the beltline curve to account for the effect of fast neutrons.

5.3.2.1.3 Operating Limits During Heatup, Cooldown, and Core operation

The results of the analyses are a set of operating limits for

5.3.2.1.4 Reactor Vessel Annealing Inplace annealing of the reactor vessel because of radiation embrittlement is not anticipated to be necessary because the predicted value of adjusted reference temperature does not exceed 2000F (see 10 CFR, Part 50, Appendix G, Paragraph IV.C) .

5.3.2.2 Operatino Procedures By comparison of the pressure versus temperature limits in Section 5.3.2.1 with intended normal operating procedures for the most severe upset transient, it is shown that the limits are not exceeded during any foreseeable upset condition. Reactor operating procedures are established so that actual transients are not more severe than those for which the vessel design adequacy has been demonstrated. Of the design transients, the upset condition producing the most adverse temperature and pressure condition anywhere in the vessel head and/or shell areas yields a minimum fluid temperature of 2500F and a mariana pressure peak of 1180 psig.

5.3.3.1 Desion 5.3.3.1.1 Description 5.3.3.1.1.1 Reactor Yessel

,- The reactor vessel shown in Figure 5.3-1 is a vertical, cylindrical pressure vessel of welded construction. The vessels

! for Limerick are designed, fabricated, tested, inspected, and stamped in accordance with the ASME Code Section III, Class A l including the Summer Addenda 1969. Design of the reactor vessel

and its support systen meets seismic Category I requirements.

The materials used in the reactor pressure vessel are shown in Table 5.2-4.

The cylindrical shell and bottom head sections of the reactor vessel are fabricated of low-alloy steel, the interior of which 5.3-11

. LGS FSAR is clad with stainless steel weld overlay. Nozzle and nozzle veld zones are unclad except for those mating to stainless steel piping systems.

Inplace annealing of the reactor vessel is unnecessary because shifts in transition temperature caused by irradiation during the 40-year life can be accommodated by raising the minimum pressurization temperature. Radiation embrittlement is not a problem outside of the vessel beltline region because the irradiation in those areas is less than 1 x 10:e nyt with neutron energies in excess of 1 hey.

l Quality control methods used during the fabrication and assembly of the reactor vessel and appurtenances ensure that design specifications are met.

! The vessel top head is secured to the reactor vessel by studs and nuts. These nuts are tightened with a stud tensioner. The vessel flanges are sealed with two concentric metal seal-rings designed to permit no detectable leakage through the inner or outer seal at any operating condition, including heating to operating pressure and temperature at a maximum rate of 100*F/hr

in any one-hour period. To detect seal failure, a vent tap is i located batveen the two seal-rings. A monitor line is attached to the tap to provide an indication of leakage from the inner j seal-ring seal.

l l 5 . 3 . 3 .1.1. 2 Shroud Support l

The shroud support is a circular plate welded to the vessel vall.

This support is designed to carry the weight of the shroud, shroud head, peripheral fuel elements, neutron sources, core plate, top guide, the steam separators, the jet pump diffusers, and to laterally support the fuel assemblies. Design of the shroud support also accounts for pressure differentials across the shroud support plate, for the restraining effect of components attached to the support, and for earthquake loadings.

The shroud support design is specified to meet appropriate ASHE code stress limits.

1 5.3.3.1.1.3 Protection of Closure Studs The BWR does not use borated water for reactivity control. This section is therefore not applicable.

. LGS FSAR resulting from operation under abnormal and accident conditions

b. To minimize the possibility of brittle fracture of the nuclear system process barrier, the following are required:

1. Impact properties at temperatures related to vessel operation are specified for materials used in the reactor vessel

2. Expected shifts in transition temperature during design life as a result of environmental conditions, such as neutron flux, are considered in the design. Operational limitations ensure that RTyer temperature shifts are accounted for in reactor operation.

3. Operational margins to be observed with regard to the transition temperature are specified for each mode of operation.

5 . 3 . 3 .1.3 Power Generation Design Basis l' The design of the reactor vessel and appurtenances meets the following power generation design bases:

a. The reactor vessel has been designed for a useful life of 40 years.

b. External and internal supports that are integral parts

, of the reactor vessel are located and designed so that

! stresses in the vessel and supports that result from i

reactions at these supports are within ASME Code limits.

c. Design of the reactor vessel and appurtenances allows for a suitable program of inspection and surveillance.

High strength bolts are used to secure the flange of the reactor vessel support skirt to the top flange of the ring girder. The ring girder is fabricated of ASTM A-36 structural steel according to AISC specifications.

l 5.3.3.1.4.2 Control Rod Drive (CRD) Housings The CRD housings are inserted through the CRD penetrations in the reactor vessel bottom head and are velded to the reactor vessel.

Each housing transaits loads to the bottom head of the reactor.

These loads include the weights of a control rod, a CRD, a control rod guide tube, a four-lobed fuel support piece, and the four fuel assemblies that rest on the fuel support piece. The housings are fabricated of Type 304 austenitic stainless steel.

5.3.3.1.4.3 Incore Neutron Flux Monitor Housings Each incore neutron fluz monitor housing is inserted through the incore penetrations in the bottom head and is velded to the inner surface of the bottom head.

An incore flux monitor guide tube is velded to the top of each housing and either a source range monitor / intermediate range monitor (SR5/IRH) drive unit or a local power range monitor (LPRB) is bolted to the seal / ring flange at the bottom of the housing (see Sections 7.6 and 7.7) .

5.3.3.1.4.4 Reactor Vessel Insulation The reactor vessel top head insulation is designed to permit complete submersion in water during shutdown without loss of insulating material, contamination of the water, or adverse effect on the insulation efficiency after draining. All reactor vessel insulation is of the stainless steel, reflective type.

The top head insulation framework is designed to seismic Category I requirements and is used as an anchor point for reactor vessel head spray and vent piping.

The insulation above the reactor vessel stabilizer brackets is close-fitting, freestanding insulation designed to be 100g removable for inservice inspection of the reactor vessel.

i l The insulation below the stabilizer brackets is suspended fron l the brackets to allow a minimum of 8 inches annular clearance between the reactor vessel and the insulation for remote inservice inspection of the reactor vessel. The suspended insulation is also equipped with removable access ports.

5.3.3.3 Fabrication Methods The RPV is a vertical, cylindrical pressure vessel of welded construction fabricated in accordance with ASME Section III, Class I requirements. All fabrication of the RPV is performed in accordance with GE approved drawings, fabrication procedures, and test procedures. The shell and vessel head are made from formed low-alloy steel plates, and the flanges and nozzles from low-l alloy steel forgings. Welding performed to join these vessel components is 17 accordance with procedures qualified in ASME Section III and II requirements. Weld test samples are required for each procedure for major vessel full penetration welds.

, submerged are and manual stick electrode welding processes are employed. Electroslag velding is not permitted. Preheat and

, interpass temperatures employed for welding of low-alloy steel meet or exceed the requirements of ASME Code Section III, subsection NA. Postweld heat treatment of 11000F minimum is appliad to all low-alloy steel welds.

All previous BWR pressure vessels employed similar fabrication methods. These vessels have operated for periods of up to 16 years and their service history is excellent.

The vessel f abricator, Chicago Bridge and Iron Co., has had extensive experience with GE reactor vessels dating back to 1966.

CBI Nuclear Co. was formed in 1972 from a merger agreement between Chicago Bridge and Iron Co. and GE and has continued as the primary supplier for GE domestic reactor vessels.

5.3.3.6 Operatina conditions Procedural controls on plant operation are implemented to hold thermal stresses within acceptable ranges. These restrictions on coolant temperature are:

a. The average rate of change of reactor coolant temperature during normal heatup and cooldown shall not exceed 1000F during any one-hour period.

The item c limit further restricts operation of the recirculation pumps to avoid high thermal stress effects in the pumps and piping, while also minimizing thermal stresses on the vessel nozzles.

The above operational limits are maintained to ensure that the stress limits within the reactor vessel and its components are within the thermal limits to which the vessel is designed for normal operating conditions. To maintain the integrity of the vessel if these operational limits are exceeded, the reactor vessel is also designed to withstand a limited number of transients caused by operator error. Also, for abnormal 5.3-17 l

. LGS FSAR operating conditions where safety systems or controls provide an automatic temperature and pressure response in the reactor vessel, the reactor vessel integrity is maintained since the severest anticipated transients are included in the design conditions. Therefore, it is concluded that vessel integrity is maintained during the most severe postulated transients, since all such transients are evaluated in the design of the reactor vessel. The postulated transient for which the vessel has been designed is shown in Figure 5.2-5 and discussed in Section 5.2.2.

5.3.3.7 Inservice Surveillance Inservice inspection of the RPV is in accordance with the requirements of the 1974 Edition of the ASME BSPY Code,Section II, including the Summer 1975 Addenda. The vessel is examined once prior to startup to satisfy the preoperational requirements of the ASME Code,Section II. Subsequent inservice inspection is scheduled and performed in accordance with the requirements of 10 l CFR Part 50.55a, Subparagraph (g).

The materials surveillance program monitors changes in the fracture toughness properties of ferritic materials in the

, reactor vessel beltline region resulting from their exposure to l

neutron irradiation and the thermal environment. Specimens of actual reactor beltline material are exposed in the reactor l vessel and periodically withdrawn for impact testing. Operating l r procedures are modified in accordance with test results to ensure adequate brittle fracture control.

Material surveillance programs and inservice inspection programs are in accordance with applicable ASHE code requirements, and provide ensurance that brittle fracture control and pressure vessel integrity are maintained throughout the service life of the RPY.

Inservice inspection and testing of the reactor coolant pressure boundary is discussed in detail in Section 5.2.4.

(1) The Limerick 1 RPV design results in this component experiencing a predicted end-of-life (EOL) fluence of 1.6 x 1017 n/cm2 at 1/4 of the thickness. This fluence, based on a conservatively assumed Cu content of 0.18% and a measured phosphorous content of 0.011%,

yields an estimated EOL RT NOT of +14*F. The EOL estimate is in accordance with Regulatory Guide 1.99, Revision 1.

(2) This component meets the CVN test requirements of 45 ft-lbs absorbed energy and 25 mils lateral expansion at +10*F.
