| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN INTRODUCTION IWA-2420 of the 2001 Edition of Section XI with Addenda through 2003 specifies the contents of Inservice Inspection Plans and Schedules. HNP utilizes a two-part plan developed using industry standard Schedule Works software to develop applicable tables.
| |
| These are:
| |
| : 1. The Fourth Interval Inspection Plan. This plan was developed to provide scheduling for all of the Class 1,2, and 3 components for the Fourth Interval as defined by the applicable HNP Boundary Diagrams. This document is primarily used to determine if Code scheduling requirements are being met. This plan includes:
| |
| The Fourth Interval and period dates.
| |
| The Edition and Addenda that apply to the required examinations.
| |
| The Code classification and identification of all components subject to examination.
| |
| The identification of each of the components selected for examination and the successive exams from prior periods.
| |
| The identification of drawings showing the location of items requiring examination.
| |
| Code examination requirements (UT, MT, etc.) for each component selected for examination.
| |
| Code Cases proposed for use and the extent of their application.
| |
| NRC Alternatives that change Code examination requirements.
| |
| : 2. Outage Plans. These plans will be developed for each outage to provide information specific to each outage. These plans include:
| |
| The listing of components selected for examination during the outage.
| |
| The examination procedures for each component.
| |
| The description of alternative examinations and identification of components to be examined using alternative methods.
| |
| The identification of calibration blocks used for ultrasonic examination of components.
| |
| Note: Schedule Works also provides a column in the Fourth Interval Inspection Plan that lists procedures to be used. This information is only needed for outage related activities and is found in the Outage Plan. It is considered for information only in this plan because procedures are subject to change throughout the interval.

| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS SCOPE OF EXAMINATIONS Per IWA-1400 of the Section XI Code, the Owner is responsible for determining the appropriated Code Class, for identifying the system boundaries for each class of component subject to examination, and for identifying the components exempt from examination. This requirement is met by the following:
| |
| Appropriate Code Class The determination of the appropriate Code Class for each component is made by SNC Design Organization and designated on the ISI Boundary Diagrams. These Boundary Diagrams are controlled by SNC Design Organization.
| |
| System Boundaries The system boundaries for each Code Class are designated on the ISI Boundary Diagrams.
| |
| Exempt Components The components exempt from examination are shown below in this Bases Document.
| |
| EXAMINATION REQUIREMENTS The examination requirements for the Class 1 components identified on the Boundary Diagrams are defined in IWB-2500 for each examination category. Categories in the 2001 Edition of Section XI with Addenda through 2003 are:
| |
| * Category B-A Pressure Retaining Welds in the Reactor Vessel
| |
| * Category B-B Vessels other than the Reactor Vessel (Not Applicable)
| |
| * Category B-D Full Penetration Welds of Nozzles in Vessels
| |
| * Category B-F Pressure Retaining Dissimilar Metal Welds
| |
| * Category B-G-1 Pressure Retaining Bolting Greater than 2 Diameter
| |
| * Category B-G-2 Pressure Retaining Bolting 2 and Less in Diameter
| |
| * Category B-J Pressure Retaining Welds in Piping
| |
| * Category B-K Valves
| |
| * Category B-L-1 Pressure Retaining Welds in Pump Casings (Not Applicable)
| |
| * Category B-L-2 Pump Casings
| |
| * Category B-M-1 Pressure Retaining Welds in Valve Bodies (Not Applicable)
| |
| * Category B-M-2 Valve Bodies
| |
| * Category B-N-1 Interior of Reactor Vessel (See Volume 4)
| |
| * Category B-N-2 Integrally Welded Core Support Structures/Interior Attachments (See Volume 4)
| |
| * Category B-O Pressure Retaining Welds in Control Rod Housings
| |
| * Category B-P Pressure Testing (See Volume 6)

| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS These examination requirements are not applicable to components exempt from examination per IWB-1220. Components exempt from examination are only subject to the pressure testing requirements. (See the Exemptions Section below for more detail).
| |
| Additionally, there are cases in which SNC deviates from the Code specified examinations; with NRC concurrence. (See the Deviations Section below for further detail). These deviations occur when:
| |
| : 1. Meeting the Code requirements are impractical due to configuration, accessibility, or other factors.
| |
| : 2. The use of later editions or addenda of the Section XI Code, Code Cases, etc., are more appropriate or more desirable for use than the existing requirements.
| |
| EXEMPTIONS IWB-1220 defines the components that are exempt from the examination requirements of IWB-2500. Per 10 CFR 50.55a(b)(2)(xi), licensees must use IWB-1220 of the 1989 Edition of Section XI, in lieu of the 2001 Edition of Section XI with Addenda through 2003. IWB-1220(a) of the 1989 Edition states that, components that are connected to the reactor coolant system and part of the reactor coolant pressure boundary and that of such size and shape so that upon postulated rupture the resulting flow of coolant from the reactor coolant system under normal plant operating conditions is within the capacity of makeup system which are operable from on-site emergency power. In determining the size of the liquid and steam lines excluded from NDE examination, liquid lines were defined as those that penetrate the RPV below the normal water level and steam lines as those which penetrate the RPV above the normal water level.
| |
| GE Nuclear Energy Report GE DRF Number B11-00788 was used for the 3rd Interval exemptions and its methodology will be used for the 4th Interval. The exception is that Condensate Make-up to the main condenser was eliminated as a make-up source because the condensate pumps are not supplied by the diesel generators. Without Condensate Make-up, the reactor coolant makeup is RCIC (360 GPM) and CRD (60 GPM) for a total of 420 GPM. The basic formula for a leak rate at 1050 psi (per GE DRF Number B11-00788) is:
| |
| Inside Diameter of a Water Line = (Square Root of the total makeup flow) 18.799 Inside Diameter of a Steam Line = 2 times the value of a water line H2 Basis Doc - Class 1 Page 2 of 43 Rev. 1
| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS The square root of 420 is 20.494. Therefore, for water the inside diameter exempted is 1.09 and for steam the inside diameter exempted is twice the value of water or 2.18.
| |
| Per Piping Specification (A-21000), there are three Class 1 piping specifications - DBA (Schedule 160), DCA (Schedule 80) and DLA (Schedule 160). After evaluation of the inside diameter for these Piping Specifications it was determined that the following exemptions may be applied.
| |
| IWB-1220(a) EXEMPTIONS NPS 1 and smaller for Schedule 80 and Schedule 160 water lines.
| |
| NPS 2 and smaller for Schedule 80 steam lines and NPS 2.5 for Schedule 160 steam lines.
| |
| Previously, per GE DRF Number B11-00788 (including Condensate Makeup to the condenser), the exemption was 2.5 for water lines and 5.0 for steam lines. The following P&IDs were reviewed to determine if there are lines that were previously exempted but that are not exempt per the new IWA-1220(a) exemptions.

| |
| The 2 socket-welded RPV bottom head drain to the RWCU system as shown on P&ID H-26003 (Reference isometric H-51221). These welds are shown on ISI Figure A-28A and are designated as 2B31-1RC-2DR-1 through 50.
| |
| H2 Basis Doc - Class 1 Page 3 of 43 Rev. 1
| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS The 2 socket-welded drain line on each of the two loops as shown on P&ID H-26003. (Reference isometrics S-30804 and S-30809). These welds are shown on ISI Figure A-16A and A-18a and are designated as 2B31-1RC-2A-1 through 10 and 2B31-1RC-2B-1 through 12.
| |
| The 1-1/2 socket-welded SLC line as shown on P&ID H-26009 (see isometrics S-30959, S-31455, S-31489, S-31435). These welds are shown on ISI Figures A-39 through A-41 and are designated as 1C41-1SB LC-1.5-1 through 85. The two butt welds on the safe-end are designated as 1C41-1SBLC-2-1 and 1C41-1SBLC-2-2 and are shown on Sketch 2-BE-3.
| |
| The 2N16A&B nozzles penetrate the RPV in water space. Per Sketch 2-BE-2, a dissimilar metal weld joins the 304 stainless steel safe-end to the Inconel nozzle.
| |
| These Category B-F welds are designated as 2B11-1INST-2A-1 (2N16A) and 1B11-1INST-2B-1 (2N16B) and they are non-exempt because the ID is greater than1.09.
| |
| Per Sketch 2-BE-2, the safe-end has a socket weld end prep for a 2 pipe. While no drawings could be found for the piping, a drawing was found for the 1N11A&B nozzles which is essentially the same as the 2N16A&B nozzles. This drawing (H16964) indicates that at there is a 2 X 1-1/2 coupling welded to the safe-end.
| |
| The 1-1/2 coupling then is further reduced in size by a 1-1/2 X 1 reducing insert.
| |
| These socket welds are designated 2B11-1INST-2A-2 and 3(2N16A) and 2B11-1INST-2B-2 and 3 (2N16B) and are not exempt. Per P&ID H-26001 the balance is exempt 1 DCA pipe (Schedule 80S with a 0.957 ID ).
| |
| The 2N11A&B and 2N12A&B nozzles are the same size as the 2N16A&B nozzles; however, they penetrate the RPV near the steam separator. Inventory lost as a result of a break in these welds would consist of steam; therefore, they are exempt since they are smaller than the IWB-1220(a) exemption for steam (2.18).
| |
| DEVIATIONS TO CLASS 1 ISI CODE REQUIREMENTS IWB-2500 provides the examination requirements for Class 1 components. As defined in Volume 1 of this ISI Plan, these Code requirements may be deviated from by:
| |
| * The use of NRC approved alternatives to Code requirements per 10 CFR 50.55a(a)(3).
| |
| * The use of NRC approved Relief Requests per 10 CFR 50.55a(g)(6) when an examination requirement by the Code is determined to be impractical.
| |
| * The use of Code Cases approved for use by the NRC through publication in Regulatory Guide 1.147.

| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS Code Case N-663 Code Case N- 663 provides that ... in lieu of the surface examination requirements for piping welds of Examination Category B- F ( NPS 4 and larger), and B- J ( NPS 4 and larger),surface examinations may be limited to areas identified by the Owner as susceptible to outside surface attack. The susceptibility criteria are listed in Table 1 of Code Case N- 663 for two types of degradation mechanisms. No Class 1 welds have been identified as being susceptible to outside surface attack. The basis is discussed below:
| |
| External (O. D.) Chloride Stress Corrosion Cracking of Austenitic Stainless Steel For this cracking to be postulated per Code Case N-663, the:
| |
| Operating temperature must be greater than 1500F, and the piping outside surface is within 5 pipe diameters of a probable leak, and the piping outside surface is covered with nonmetallic insulation that is not in compliance with Regulatory Guide 1.36 or equivalent requirements.
| |
| Evaluation: All of the austenitic piping within the ISI scope is within the reactor coolant pressure boundary (RCPB). Per Section 5.2.3.3 of the FSAR, Compatibility With External Insulation and Environmental Atmosphere, the RCPB is insulated with an all-metal (stainless steel and aluminum) reflective-type insulation in compliance with Regulatory Guide 1.36 (February 1973). This type of insulation does not contain any silica, fluorides, or chlorides. It does not contribute to surface contamination, and it has no effect on the stainless steel components of the RCPB. The insulation is designed for a 40-year service life; however, this insulation is monitored so that actions are taken to provide reasonable assurance that the insulation is capable of fulfilling its intended function for 40 years and beyond.
| |
| Other Outside Surface Initiated Mechanisms Per Code Case N-663, items that are susceptible to an outside attack should be identified by a plant-specific service history review. This review should include plant-specific processes and programs that minimize chlorides and other contaminants.
| |
| Evaluation: Due to ID initiated IGSCC, numerous examinations of the austenitic welds and adjacent base material has been performed over the past 15+ years and no evidence of OD initiated stress corrosion cracking has been observed. (Note: All of the stainless steel piping was replaced to the extent practical with 316NG which is relatively immune to stress corrosion cracking). Additionally, ISI personnel associated with Hatch over the past 20 years have no knowledge of OD originated cracking in austenitic piping 4 diameter and over. (There has been OD originated cracking in some socket welds due to fatigue, but socket weld are not covered by Code Case N-663). Plant-specific processes and programs that minimize chlorides and other contaminants are:

| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS The SNC purchase specification for thermal Insulation for stainless steel, require insulation suppliers to provide material that meets the criteria of Regulatory Guide 1.36.
| |
| Each Purchase Order imposes Reg. Guide 1.36 and ANSI N45.2 covering leach able properties and their acceptable levels for contact with Stainless Steel.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS ISI PLAN TABLES The ISI Plan Tables are generated by the industry standard ScheduleWorks ISI software using a standard format. It should be noted that the Scope/Method/Procedure field is for information only. This information may be changed during an outage by authorized IDDEAL software
| |
| `users at the site, but it will not be reflected in the ISI Plan until the plan is updated after the outage. When using these tables the user needs to understand the following symbols:
| |
| Scheduled "s" To schedule a component, place the identifier "s" in the required period/outage.
| |
| Completed "c" Upon exam completion for a scheduled component and by uploading the outage scope from IDDEAL back to ScheduleWorks, an "s" will be updated to completed "c".
| |
| Re- "r" Once a component has been scheduled, and you wish to reschedule to another outage, replace the scheduled scheduled "s" with a rescheduled "r" and enter an "s" in the new outage schedule.
| |
| Expanded "e" To increase a work scope without taking code credit in the percentage calculations, enter an Scope expanded "e".
| |
| Expanded "E" Upon exam completion of an expanded scope and by either uploading the outage scope from Scope IDDEAL or manually changing the letter to an upper case "E" the exam scope is completed.
| |
| Completed Additional "a" After an initial expanded work scope has been identified and you wish to add an increased Scheduled expanded work scope, enter an additional expanded scope "a".
| |
| Additional "A" Upon exam completion of an additional expanded scope and by either uploading the outage scope Completed from IDDEAL or manually changing the letter to an upper case "A" the exam scope is completed.
| |
| Partial "p" To track partially completed component examination requirements enter a partial "p".
| |
| Deferred "d" Once a component has been scheduled, and you wish to defer the inspection to another Outage, or Period, replace the scheduled "s" with a deferred "d" and enter an "s" in the new Outage.
| |
| Limited "l" To track limited component examinations or limited completions of requirements enter "l".
| |
| Multiple "b For multiple scheduling of the same component in successive Outages or Periods within an Interval Scheduled enter "b".
| |
| Multiple "B" Upon exam completion of a multiple scope in the same Interval and by either uploading the outage Completed scope from IDDEAL or manually changing the letter to an upper case "B" the exam scope is completed. This multiple scheduling scope will not count as completed for code calculations.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS Category B-A - Class 1 RPV Item B1.11 and B1.12 Shell Welds Configuration The HNP-2 RPV shell has four Item B1.11 Circumferential welds - 2C-2, 2C-3, 2C-4, and 2C-5 and twelve Item B1.12 longitudinal welds - 2C-1-A, 2C-1-B, 2C-1-C, 2C-2-A, 2C-2-B, 2C-2-1C, 2C-3-A, 2C-3-B, 2C-3-1C, 2C-4-A, 2C-4-B, and 2C-4-C.
| |
| 1st Interval Examinations The 1st Interval began on 9/5/79; however, HNP-2 was early updated effective 12/31/85 prior to the examination of the shell welds. This update changed the HNP-2 interval and period dates so that they coincided with the interval and period dates for HNP-1. At the time of the update, the remaining examinations in the original 1st interval (all B1.11 and B1.12 exams) were required to be performed during the 1st period of the new 2nd interval (essentially where they had been originally scheduled).
| |
| These examinations were performed in Winter 1988 during the 1st Period of the 2nd Interval, as required. The scope was determined using the 1974 Code/Summer 1975 requirements, which was 5% of each circumferential weld and 10% of each longitudinal weld. Examinations were performed by SWRI to the 1980 Code requirements using mechanized equipment. These examinations completed the 1st Interval requirements.
| |
| 2nd Interval Examinations 1st Interval examinations were performed in 1988; therefore, 2nd Interval examinations were due by the 1998 outage. However, 10 CFR 50.55a(g)(6)(ii)(A) was issued by the NRC to require all licensees to augment their RPV examination by implementing once, as part of the inservice inspection interval in effect on September 8, 1992, the examination requirements for reactor vessel shell welds specified in Item B1.10 of Examination Category B - A, "Pressure Retaining Welds in Reactor Vessel," in Table IWB - 2500 - 1 of subsection IWB of the 1989 Edition of section XI, Division 1, of the ASME Boiler and Pressure Vessel Code.
| |
| GPC evaluated whether to perform these examinations from the ID or the OD of the RPV and it was determined that the OD examinations had significantly more coverage. These OD examinations were performed during the Fall 1995 refueling outage. All welds had greater than 90% coverage, except for Weld 2C-2. GPC letter HL-5250 dated October 29, 1996 requested relief for the limited examination coverage of weld 2C-2, which had only 83.7% coverage due to stabilizer brackets being welded directly onto 2C-2.
| |
| Approval was granted by the NRC Safety Evaluation dated February 21, 1997. These examinations completed the augmented examination requirements and the 2nd Interval examination requirements.
| |
| H2 Basis Doc - Class 1 Page 8 of 43 Rev. 1
| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS 3rd Interval Examinations Since 2nd Interval examinations were performed in the Fall 1995 during the last outage of the 2nd 10-year Interval, the next examinations are due at the end of the 3rd Interval.
| |
| HNP-2 changed to a 24 month operating cycle beginning after the February 2003 outage and the next outages are scheduled for February 2005 and February 2007. The February 2007 outage is 14 months past the end of the interval and cannot be used for 3rd Interval activities; therefore, the examinations were scheduled during the February 2005 outage.
| |
| Per Table IWB-2500-1, Category B-A of the 1989 Code all of the circumferential welds and the longitudinal welds require a volumetric examination. However, to support shorter outage windows, relief (see RR-38) has been requested, based on the technical basis provided in BWRVIP-05, to allow the volumetric examination of the four Item B1.11 circumferential welds to be deleted. RR-38 granted by NRC SE dated 1/28/05.
| |
| The twelve longitudinal weld examinations were examined in February 2005 (2R18) using the 1989 Edition of Section XI.
| |
| 4th Interval Examinations The twelve longitudinal weld examinations will be scheduled for examination in February 2015 (2R23). Relief will be required using BWRVIP-05 to allow the deletion of the volumetric examination of the four Item B1.11 circumferential welds.

| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS Category B-A - Class 1 RPV Item B1.21 Bottom Head Circumferential Weld Configuration There is one circumferential weld located on the bottom head. Circumferential weld 2C-7 connects the dome to the torus. It is located inside the support skirt.
| |
| First and Second Interval Examinations HNP-2 was early updated effective January 1, 1986. This update changed the HNP-2 Code, interval dates, and period dates so that they coincided with HNP-1. (Therefore, the 3rd Period of the 1st Interval for HNP-2 became the 1st Period of the 2nd Interval). Per Relief Request 2.1 (submitted in the 2nd Interval Program) the required 1st Interval examinations were to be completed for 2C-7 (approximately 5% of the length per the 1974/Summer 1975 Code) in the 1st Period of the 2nd Interval. Additionally, weld 2C-7 was required to be 100% examined during the 2nd Interval to meet the 1980 Code requirements. Examinations were performed as follows:
| |
| * Per Note 2 in the 2nd Interval ISI Plan, 2C-7 was examined in 1986 to meet the 5%
| |
| requirement of the 1974 Code. From the data sheet, the weld was examined in excess of 5%, but the exact amount of coverage was indeterminate. This examination satisfied the 1st Interval requirements.
| |
| * Weld 2C-7 was re-examined during the Fall 1995 outage (3rd Period of the 2nd Interval) using GERIS to meet the 2nd Interval requirements using the 1980 Code with Addenda through Winter 1981. Ninety-three non-geometric indications were evaluated and found acceptable. Code coverage was in excess of 95%. This examination satisfied the 2nd Interval requirements.
| |
| Third Interval Examinations Scope: 2C-7 Since the 2nd Interval examination of 2C-7 was performed during 1995, the 3rd Interval examination of 2C-7 was performed in February 2005 (2R18) using the 1989 Code.
| |
| 4th Interval Examinations Scope: 2C-7 Since the 3rd Interval examination of 2C-7 was performed during 2005, the 4th Interval examination of 2C-7 will be scheduled for February 2015 (2R23).

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS Category B-A - Class 1 RPV Item B1.22 Bottom Head Meridional Welds Configuration The HNP-2 bottom head consists of a 4-piece dome welded together with four meridional welds 2BHD-A thru D and a 7-piece torus welded together with seven meridional welds 2BHT-A thru G. (There is a support skirt welded to the bottom head between circumferential welds 2C-7 and 2C-5 that covers a portion of each meridional torus weld).
| |
| First and Second Interval Examinations HNP-2 was early updated effective January 1, 1986. This update changed the HNP-2 Code, interval dates, and period dates so that they coincided with HNP-1. (Therefore, the 3rd Period of the 1st Interval for HNP-2 became the 1st Period of the 2nd Interval). Per Relief Request 2.1 (submitted in the 2nd Interval Program) original 1st Interval examinations were to be completed for the eleven meridional welds (approximately 10%
| |
| of the length of each of the eleven welds per the 1974/Summer 1975 Code) during the same time frame they were originally scheduled (originally the 3rd Period of the 1st Interval which changed to the 1st Period of the 2nd Interval). Additionally, one of the seven bottom head torus meridional weld was required to be 100% examined, to the extent practical, during the 2nd Interval per the 1980 Code.
| |
| Per information supplied in Note 3 of the 2nd Interval ISI Plan and as shown on the applicable data sheets:
| |
| * Each of the four dome meridional welds was examined in Fall 1986 (1st Period of the 2nd Interval) to the extent practical (28.5 to 30). The dome meridional welds were estimated to be approximately 60 long, with about half of each weld inaccessible due to the control rod drive penetrations.
| |
| * Each of the seven torus meridional welds was examined in Fall 1986 (1st Period of the 2nd Interval) to the extent practical (30). Limitations existed due to the RPV skirt weld.
| |
| More than 10% of each of the eleven meridional welds was examined; therefore, the original 1st Interval 1974 Section XI requirements were satisfied. Additionally, since each meridional weld had been examined to the extent practical, the 2nd Interval requirement per the 1980 Code to examine one meridional weld, to the extent practical, was also satisfied.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS Third Interval Examinations Since the 2nd Interval examinations were completed in Fall 1986 (1st Period of the 2nd Interval), the 3rd Interval examinations were completed during the 2R13 Spring 1997 outage (1st Period of the 3rd Interval) per the requirements of the 1989 Code. The 1989 Code required that the accessible length of all the meridional welds be examined.
| |
| Examinations were pre-Appendix VIII and had the following limitations:
| |
| 2BHD-A, B, C, D Manual examinations limited to 31 of each of the four welds. Limitations were due to CRD interference.
| |
| 2BHT-A, B, C, D, E, F, G GERIS automated scans (GE procedure UT-HAT-702V0, Rev. 3) were used to examine 38 of each weld.
| |
| Supplemental manual scans were performed on 11 yielding a total of 49 of each weld being examined.
| |
| Composite coverage was 88.7%. Limitations were due to the skirt weld.
| |
| Upjohn Welds GE SIL 651 was subsequently issued on August 7, 2003, to notify the industry of flaws detected during Appendix VIII qualified ISI examinations at Fermi in RPV seams that were welded using the upjohn welding process. Pre-Appendix VIII UT examinations at Fermi did not report these flaws; however, review of the previous examination results showed that indications were present in the earlier data and were the same size as reported for the Appendix VIII examinations. GE indicated that these flaws were not reported in previous examinations because the indication did not require recording under the pre-Appendix VIII rules. Subsequent implementation of Appendix VIII has increased the sensitivity of ISI techniques and has resulted in more stringent data recording requirements.
| |
| Due to the CE work load during fabrication, there were times when all of the head positioners were in use and an upjohn weld process was used. Torus head segment plates were placed vertically on the floor end-to-end and a manual stick weld process was used. Welding started at the floor and the stringers were run from the plate ID to the plate OD in a horizontal position. After the first layer was made, subsequent layers would be added, continuing until the top of the plate was reached. The issue with this type of weld was that during the radiograph process, indications such as slag or cracks could have been missed, because only the end of the indication would be seen.

| |
| Unit 2 lower dome weld seams 2BHD-A thru D Unit 2 lower head torus weld seams 2BHT-A thru G The lower dome weld seams and the lower head torus weld seams were examined during 2R13. These examinations were all pre-Appendix VIII. Because the top head is examined on the refueling floor it was determined that during next Appendix VIII examinations, if there were indications, the dose would be low while resolving the indications. However, because of dose issues associated with resolving potential indications when performing Appendix VIII examination on the lower head welds, it was determined that they would be re-examined during 2R18 (while automated GERIS equipment was onsite for the RPV examinations). The rationale was that if a significant number of indications were found during the manual examinations, the automated GERIS equipment (which is to be onsite during the RPV examinations) could be used to better characterize the indications.
| |
| Manual type Appendix VIII qualified examinations were performed on each of the lower dome and lower head welds, to the extent practical, in February 2005 (2R18) using the 1989 Code. No reportable indications were detected.
| |
| 4th Interval Examinations Since the 3rd Interval examinations were completely redone in February 2005 (2R18) per Appendix VIII requirements, the 4th Interval examination will be scheduled for February 2015 (2R23).

| First Interval Examinations 5% of the 2HC-1 was examined in Spring 1985 to meet the 1974 Section XI Code with Summer 1975 addenda requirements. This examination was prior to the early update and it completed the 1st Interval requirements.
| |
| Second Interval Examinations The weld was examined in 1992 to the extent practical per the 1980 Edition of Section XI. Coverage was 97% with limitations due to the lifting lugs. This examination satisfied the 2nd Interval requirements.

| |
| First Interval Examinations Four of the welds - 2HC-1-A, 2HC-1-C, 2HC-1-E, and 2HC-1-G - were examined in 1985 (2nd Period of the 1st Interval) to the requirements of the1974 Edition of Section XI (with Addenda through Summer 1975) prior to the early Code update. Only 10% of each weld was required to be examined.
| |
| After the 1985 outage, HNP-2 was early updated effective January 1, 1986. This update changed the HNP-2 Code, interval dates, and period dates so that they coincided with HNP-1. (Therefore, the 3rd Period of the 1st Interval for HNP-2 became the 1st Period of the 2nd Interval). Per Relief Request 2.1 (submitted in the 2nd Interval Program) the remaining four 1st Interval examinations would be need to be completed to meet the 1974 Code requirements (approximately 10% of the length of each of the four welds per the 1974/Summer 1975 Code). In 1986 (new 2nd Interval, 1st Period) at least 10% of the length of the four remaining meridional welds (2HC-1-B, 2HC-1-D, 2HC-1-F, and 2HC-1-H) was examined. These examinations combined with the 1985 examinations completed the original 1st Interval examination requirements.

| |
| The 1989 Code required that each weld be 100% examined to the extent practical. Welds 2HC-1-B, D, F, and H were examined during 2R13 and welds 2HC-1-A, C, E, and G were examined during 2R14. All of these examinations were pre-Appendix VIII; however, even though they are Upjohn welds, re-examination was not performed because there is not a dose issue associated with the potential evaluation of indications (as compared to the bottom head). Note: Since weld 2HC-1-A was the only weld examined during the 2nd interval, the successive examination requirements of IWB-2420(a) were not applicable for 3rd Interval scheduling purposes.

| |
| Second Interval Examinations Segments of the weld were examined in 1991 and in 1994. Then, the entire length of the weld was examined in 1995 (3rd Period of 2nd Interval) using GERIS automated exams from the shell side (44.7% coverage) and manual supplemental exams (67.9% coverage) from the flange surface. This examination completed the 2nd Interval requirements and re-zeroed the examination, so that in future intervals 100% of the length could be examined at one time.

There are 29 RPV nozzles installed on the RPV using full-penetration welds. Nozzle 2N15 (bottom head drain) is completely inaccessible due to the proximity of the CRDs. Relief similar to that submitted in the 3rd Interval via RR-3 will be needed.

| |
| &D, 2N4C&D, 2N5A, 2N6A, 2N7, and 2N9 as shown in the 1st Interval column in Table 1-1. However, as discussed in the Introduction (effective December 31, 1985) the HNP-2 Code, interval dates, and period dates were updated so that they coincided with HNP-1.
| |
| The remaining 1st Interval nozzle examinations (nozzles 2N2A, 2N2B, 2N2D, 2N2G, 2N2K, 2N3C, 2N4A, 2N4B, 2N5B, 2N6B, 2N8A, and 2N8B) were examined from 1986 through 1989 during the 1st Period of the 2nd Interval (originally the 3rd Period of the 1st Interval).

| |
| : 1. (Note: Prior to the early update the 2nd Interval for HNP-2 was scheduled from 9/5/89 through 9/5/99).
| |
| As shown in Table 1-1, 2nd Interval examinations were performed from 1988 through 1994 for nozzles 2N1A, 2N1B, 2N2B, 2N2C, 2N2E, 2N2F, 2N2H, 2N2J, 2N3A, 2N3B, 2N3C, 2N3D, 2N4A, 2N4B, 2N4C, 2N4D, 2N5A, 2N6A, 2N6B, 2N7, and 2N9.
| |
| Second Interval examinations were also performed in 1997 for 2N2A, 2N2D, 2N2G, 2N2K, 2N8A, and 2N8B. While the 1997 outage was designated as the first outage in the new 3rd Interval, before the early update, this outage would have occurred during the 2nd Interval. Additionally, the 1st interval examination of these nozzles had been performed about 9 to 10+ years earlier. Therefore, the examination of these six nozzles in 1997 was appropriate.
| |
| The 2nd Interval examination of 2N5B was not performed until the Spring 2000 outage.
| |
| While this outage was designated as the first outage of the new 2nd Period of the 3rd Interval, before the early update, this outage would have occurred about 6 months past the end of the 2nd Interval (the old 2nd Interval would have ended on 9/4/99) which was acceptable per IWB-2412. Additionally, the 1st interval examination of these nozzles had been performed about 10+ years earlier. Therefore, the examination of this nozzle in 2000 was acceptable. These examinations closed out the 2nd Interval requirements.

| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS Third Interval Examinations Per Table IWB-2500-1, Category B-D of the 1989 Code 100% of these welds are required to be volumetrically examined.
| |
| As discussed above, because of the early update, some 1st Interval examinations were performed in the new 2nd Interval and some 2nd Interval examinations were performed in the new 3rd Interval. This approach, while technically sound, leads to difficulties in reporting (e.g., was the examination a 1st Interval examination or was it a 2nd Interval examination). Therefore, a philosophical change was made for the 3rd Interval such that all of the 3rd Interval examinations would be completed by the end of the new 3rd Interval.
| |
| This change required that if a 2nd Interval examination was performed in the 1st or 2nd Period of the new 3rd Interval, that the weld would be re-examined in the 3rd Period for 3rd Interval credit. There were seven cases where welds were examined for 2nd Interval credit in the new 3rd Interval and then re-examined for 3rd Interval credit. Note: In several cases, additional welds were re-examined to establish a pattern for the 4th Interval such that automated equipment would only be needed during two outages.
| |
| This change is technically appropriate because the Section XI Code intent is to perform an examination of each nozzle in the 1st interval and then to re-examine each nozzle about every 10 years. As shown in Table 1-1 the philosophy of examining each weld every 10 years is maintained.
| |
| Table IWB-2500-1 of the 1989 Code requires that the Category B-D examinations be spread out during the 3rd interval such that 25% to 50% of the examinations are performed by the end of the 1st Period and the remainder by the end of the 3rd Interval.
| |
| This requirement was not specifically met for the examinations being credited for the 3rd Interval because per Table 1-1 only six welds were examined for 3rd Interval Code credit during the 1st Period, while at least seven would have been required. However, eleven total examinations (39% of the welds) were actually performed during the 1st Period of the 3rd Interval. It is believed that these percentages are consistent with the intent of the Table IWB-2500-1 requirement to examine 25% to 50% of the nozzle welds in the 1st period and to then examine the remainder by the end of the interval.
| |
| 4th Interval Examinations Examinations are required per the 2001 Edition of Section XI with Addenda through 2003. (Deferral of the examinations until the end of the Interval is not permitted because the deferral is for PWRs). Per Footnote 2 of Table IWB-2500-1, Category B-D, at least 25% but not more than 50% (credited) of the nozzle examinations shall be completed by the end of the first inspection period, and the remainder by the end of the inspection interval. Thirty-three percent of the examinations are scheduled in the 1st Period with the balance scheduled throughout the remainder of the 4th interval. Relief will be required for the 2N15 nozzle due to inaccessibility. (See Table 1-1).

| As shown in Table 1-2, 2nd Interval examinations were performed from 1989 through 1994 for nozzles 2N1A, 2N1B, 2N2B, 2N2C, 2N2E, 2N2F, 2N2H, 2N2J, 2N3A, 2N3B, 2N3C, 2N3D, 2N4A, 2N4B, 2N4C, 2N4D, 2N5A, 2N6A, 2N6B, 2N7, 2N8A, and 2N9.
| |
| Second Interval examinations were also performed in 1997 for 2N2A, 2N2D, 2N2G, 2N2K, and 2N8B. While the 1997 outage was designated as the first outage in the 3rd Interval, before the early update this outage would have occurred during the 2nd Interval.
| |
| Additionally, the 1st interval examination of these nozzles had been performed about 9 to 10 years earlier or less. Therefore, the examination of these six nozzles in 1997 was appropriate.
| |
| The 2nd Interval examination of 2N5B was not performed until the Spring 2000 outage.
| |
| While this outage was designated as the first outage of the new 2nd Period of the 3rd Interval, before the early update, this outage would have occurred about 6 months past H2 Basis Doc - Class 1 Page 22 of 43 Rev. 1

Additionally, the 1st interval examination of these nozzles had been performed about 10+ years earlier. Therefore, the examination of this nozzle in 2000 was acceptable. These examinations closed out the 2nd Interval requirements.
| |
| Note: Examination of the 2N4A-D Feedwater nozzle inner radius and bore were performed numerous times to meet NUREG-0619 requirements. Only one examination per each nozzle was credited for Code examination purposes. See Revised Feedwater Nozzle Inner Radius Inspection Criteria in this document for further information on these examinations.
| |
| Third Interval Examinations Per Table IWB-2500-1, Category B-D of the 1989 Code 100% of the nozzles must have their inner radius volumetrically examined.
| |
| NOTE Beginning in 2000, Relief Request RR-34, Revision 2 was used to perform an enhanced visual examination of the nozzle inner radius in lieu of the required volumetric examination of closure head nozzles 2N6A&B, 2N7, and 2N9 in lieu of the required volumetric examination.
| |
| It could have also been used for RPV nozzles 2N1A&B and 2N3A-D, but was not.
| |
| Relief Request RR-37, Revision 1 may have been used to perform an enhanced visual examination of the nozzle inner radius in lieu of the required volumetric examination for RPV nozzles 2N2A-H, 2N2J&K, 2N5A&B, and 2N8A&B. It was not used.
| |
| As discussed above, because of the early update, some 1st Interval examinations were performed in the new 2nd Interval and some 2nd Interval examinations were performed in the new 3rd Interval. This approach, while technically sound, leads to difficulties in reporting (e.g., was the examination a 1st Interval examination or was it a 2nd Interval examination?). Therefore, a philosophical change was made for the 3rd Interval such that all of the 3rd Interval examinations would be completed by the end of the new 3rd Interval.
| |
| This change required that if a 2nd Interval examination was performed in the 1st or 2nd Period of the new 3rd Interval, that the weld would be re-examined in the 3rd Period for 3rd Interval credit. There were six cases where the nozzle inner radius was examined for 2nd Interval credit in the new 3rd Interval and then re-examined for 3rd Interval credit. Note:
| |
| In several cases, additional nozzle inner radii were re-examined to establish a pattern for the 4th Interval such that automated equipment would only be needed during two outages.
| |
| This change is technically appropriate because the Section XI Code intent is to perform an examination of each nozzle in the 1st interval and then to re-examine each nozzle H2 Basis Doc - Class 1 Page 23 of 43 Rev. 1
| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS about every 10 years. As shown in Table 1-2 the philosophy of examining each nozzle inner radius every 10 years is maintained.
| |
| Table IWB-2500-1 of the 1989 Code requires that the Category B-D examinations be spread out during the 3rd interval such that 25% to 50% of the examinations are performed by the end of the 1st Period and the remainder by the end of the 3rd Interval.
| |
| This requirement was not specifically met for the exams being credited for the 3rd Interval because per Table 1-2 only six nozzle inner radii were examined for 3rd Interval Code credit during the 1st Period, while at least seven would have been required. However, eleven total examinations (43% of the total welds) were actually performed during the 1st Period of the 3rd Interval. It is believed that these percentages are consistent with the intent of the Table IWB-2500-1 requirement to examine 25% to 50% of the nozzle inner radii in the 1st period and to then examine the remainder by the end of the interval.
| |
| Examinations of the 2N4A-D Feedwater nozzle inner radius and bore were performed once during the 10-year interval to meet Alternate BWR Feedwater Nozzle Inspection Requirements. See Revised Feedwater Nozzle Inner Radius Inspection Criteria in this document.
| |
| 4th Interval Examinations Examinations are required per the 2001 Edition of Section XI with Addenda through 2003. (Deferral of the examinations until the end of the Interval is not permitted because the deferral is for PWRs). Per Footnote 2 of Table IWB-2500-1, Category B-D, at least 25% but not more than 50% (credited) of the nozzle examinations shall be completed by the end of the first inspection period, and the remainder by the end of the inspection interval. Thirty-three percent of the examinations are scheduled in the 1st Period with the balance scheduled throughout the remainder of the 4th interval. Relief will be required for the 2N15 nozzle due to inaccessibility. (See Table 1-2).
| |
| In place of a UT examination, SNC may perform a visual examination of the RPV nozzles (except for the Feedwater Nozzles) per Code Case N648-1, with enhanced magnification that has a resolution sensitivity to detect a 1-mil width wire or crack, utilizing the allowable flaw length criteria of Table IWB-3512-1 with limiting assumptions on the flaw aspect ratio. The provisions of Table IWB-2500-1, Examination Category B-D, continue to apply except that, in place of examination volumes, the surfaces to be examined are the external surfaces shown in the figures applicable to this table.
| |
| Note: Per NUREG-0619 augmented examinations of the feedwater nozzle inner radius (and bore) for a welded in thermal sleeve configuration are required every 2nd refueling outage. However, due to improved automated UT examination technology and lack of cracking in the newer thermal sleeve configurations, the frequency is now Code frequency (see Feedwater Nozzle Augmented Requirements later in this document for detailed discussion).

| |
| 10 CFR 50.55a(b)(2)(ii) states, Pressure-retaining welds in ASME Code Class 1 piping (applies to Table IWB - 2500 and IWB - 2500 - 1 and Category B - J). If the facility's application for a construction permit was docketed prior to July 1, 1978, the extent of examination for Code Class 1 pipe welds may be determined by the requirements of Table IWB - 2500 and Table IWB - 2600 Category B - J of Section XI of the ASME Code in the 1974 Edition and addenda through the Summer 1975 Addenda or other requirements the Commission may adopt.
| |
| The construction permit for HNP-2 was docketed on 12/27/72 which allowed the use of 10 CFR 50.55a(b)(2)(ii); therefore, during the 2nd and 3rd Interval updates, HNP-2 elected to use the provisions 10 CFR 50.55a(b)(2)(ii). HNP-2 used the 1974 Edition and addenda through the Summer 1975 Addenda during the 1st Interval; therefore, the use of the above provision essentially allowed the same non-exempt Category B-J welds to be selected for the 2nd and 3rd Intervals with the following caveats.
| |
| The 1974 Edition and addenda through the Summer 1975 actually requires a different 25% sampling of welds be performed each 10-year interval. Subsequent Code editions had a philosophical change - determine a sample to examined and then repeat the examination each 10-year interval. This later philosophy was utilized.
| |
| Terminal ends and high stress welds were chosen as practical to upgrade the overall selection criteria. All other requirements for B-J piping are from the 1989 Edition of Section XI.
| |
| Relief was obtained (RR-39) during the 3rd Interval to not meet two Code requirements for stainless steel and dissimilar metal welds because they are examined per the BWRVIP-75 augmented program. These requirements are:
| |
| : 1. IWB-2412 requires that except for the examinations that may be deferred until the end of the inspection interval, examinations shall be completed in accordance with Table IWB-2412-1. Table IWB-2412-1 defines a minimum and maximum number of examinations to be performed each inspection period.
| |
| : 2. IWB-2500 requires components to be examined as specified in Table IWB-2500-1.
| |
| The Extent and Frequency of Examination requires that all Category B-F welds be examined and that a minimum of 25% of Category B-J welds be examined over the ten-year ISI interval.
| |
| In lieu of the above Code requirements, the schedules and frequencies specified in the BWRVIP-75 will be used.

| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS 4th Interval ISI-ALT-3 was submitted to the NRC (and approved) to continue the process initiated by RR-39; therefore, those welds covered by the provisions of BWRVIP-075 are not included as Category B-J. (See Category XB-J).
| |
| As allowed by 10CFR50.55a(b)(2)(ii), Category B-J welds to be examined in Interval 4 will be those selected during Interval 3. However, the scope will again be slightly adjusted to enhance the examination population based on guidance from Code Case N-609. Code Case N-609 provides an alternative to Code stress-based criteria for the selection of welds and was approved for use by the NRC in Revision 14 to Regulatory Guide 1.147. This code case has three features that were considered as possible enhancements. These features and any changes to 3rd Interval scope are addressed below:
| |
| : 1. Select all terminal ends. (Note: Terminal ends are the extremities of piping runs that connect to vessels, pumps, valves, piping systems, structures, or pipe anchors, each which acts as a rigid restraint or provides at least 2 degrees of restraint to piping thermal expansion. (The problem with examining all of the terminal ends is that, in many cases, there are severe coverage restrictions). The HNP terminal ends are evaluated below and any changes to the scope were identified.
| |
| There are four feedwater nozzles and four main steam nozzles where the weld to the nozzle is a terminal end. All eight are scheduled for the 4th Interval.
| |
| There are containment penetrations with a weld to the flued head located outside the penetration. This is an anchor point for stress analysis, but is not the extremity of the piping run; therefore, it is not considered a terminal end. Six were examined in the 3rd Interval. No change will be made for the 4th Interval.
| |
| There are 13 cases where a smaller line terminates at a branch connection on a larger line. For the connection of a piping run to a piping run, there is a rule-of-thumb for coupling or de-coupling piping runs when performing a stress analysis.
| |
| This is, when the ratio of the piping diameters is 10 to 1 or greater, the connection is considered to be a terminal end. None of the 13 cases had a 10/1 or greater ratio; therefore, there are no terminal ends in this population. A total of 3 of the 13 were examined during the 3rd Interval. For the 4th Interval, no additional welds were selected.
| |
| : 2. Select dissimilar metal welds not covered under Category B-F. There are no Category B-J dissimilar metal welds. Dissimilar metal welds greater than or equal to 4 in diameter are designated as Category XB-F and are examined per VIP-075 (see VIP-075 section). Those under 4 are designated as Category B-F.
| |
| : 3. Select additional piping welds, such that the total number of circumferential butt welds (or branch connection or socket welds) selected for examination equals 25% of the total number of nonexempt circumferential butt welds (or branch connection or H2 Basis Doc - Class 1 Page 35 of 43 Rev. 1
| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS socket welds) in the reactor coolant piping system. The examinations were prorated among the Class 1 systems on the number of nonexempt welds in each system.
| |
| Additionally, within each system, examinations were distributed between line sizes prorated, on the number of nonexempt welds in each line size. Because this was an enhancement, actual proration was not met; however, as shown in the below table, welds selected are spread throughout the systems and different line sizes.

| |
| TOTAL 295 79 27%
| |
| As discussed above in the Exemptions Section, the IWB-1220(a) exemption criteria changed which required adding numerous small diameter welds to the 4th Interval examination population. A summary of theses welds is shown below.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS Category B-K - Class 1 Welded Attachments
| |
| | |
| ===Background===
| |
| In lieu of the 3rd Interval 1989 Code requirements for welded attachments, HNP examined Class 1 welded attachments per the requirements of Code Case N-509, which was originally adopted for use at HNP through relief request RR-4. Relief Request RR-4 was superseded via the endorsement of Code Case N-509 in Revision 12 to Regulatory Guide 1.147. Revision 13 subsequently annulled the Code Case; however, it was used until the end of the 3rd Interval. Revision 12 had a condition for use, in that, at least 10%
| |
| of each Item No. was required to be examined (for those items not already requiring 100%).
| |
| Beyond those requirements established below, examination of an integrally welded attachment is required if the associated component support member has deformation identified during operation, refueling, maintenance, examination, inservice inspection, or testing. An example of component support deformation is broken parts, bent parts, or pulled out parts.
| |
| Additionally, Relief Request RR-41 which adopted Code Case N-700 was submitted (and approved by the NRC) during the 3rd Interval to effectively eliminate the examination of the stabilizer brackets (for Unit 1).
| |
| 4th Interval Examinations are required per the 2001 Edition of Section XI with Addenda through 2003, as modified by 10 CFR 50.55a(b)(2)(xxi)(C). Deferral of the examinations until the end of the Interval is not permitted.
| |
| Item B10.10 - Pressure Vessels: The only Class 1 pressure vessel is the reactor pressure vessel (RPV). With a single vessel, the Code requires the examination of all welded attachments. The HNP-2 RPV is supported by a reactor skirt (Weld C-6) and has six stabilizer brackets (SB1 - SB6) welded to the shell to prevent the RPV from tilting during a seismic event. The inside surface of the support skirt weld (C-
| |
| : 6) is totally inaccessible for examination. Note: The RPV head has lifting lugs which are not considered to be in the Examination Category B-K scope. The basis for this determination is that Examination Category B-K, Table 2500-1, Footnote 1 indicates that examination is limited to those attachments providing component support per NF-1110. NF-1110 indicates that this applies only to metal elements which transmit loads between components and the building structure.
| |
| Per 10 CFR 50.55a(b)(2)(xxi)(C), the provisions of Table IWB-2500-1, 1995 Addenda must be applied to Item B10.10. The 1995 addenda allows a volumetric examination of the skirt weld if the skirt weld configuration is that shown in Figure IWB-2500-14. For HNP-2, the configuration does not match Figure 14; therefore, HNP will use Code Case H2 Basis Doc - Class 1 Page 37 of 43 Rev. 1
| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS N-323-1 for the examination of the support skirt weld. Code Case N-323-1 allows a surface examination from the accessible surface (outside) as an alternative if the inside surface is inaccessible.
| |
| Per footnote 4 of the Code, when there are multiple vessels, only one welded attachment weld on one of the vessels requires examination. However, when there is a single vessel (such as the RPV), footnote 4 does not apply and all of the welded attachment welds require examination. Code Case N-700 was developed to align the examination requirements for single vessels with those for multiple vessels. SNC proposes using Code Case N-700 to select RPV welded attachments for examination in lieu of using the Code Case N-509 footnote 4 requirements.
| |
| Code Case N-700 states that, For single vessels, only one welded attachment shall be selected for examination. The attachment selected for examination on one of the multiple vessels or the single vessel, as applicable, shall be an attachment under continuous load during normal system operation, or an attachment subject to a potential intermittent load (seismic, water hammer, etc.) during normal system operation if an attachment under continuous load does not exist. The examination of the HNP-2 RPV skirt weld will satisfy Code Case N-700 examination requirements because this weld is under a continuous load during normal system operation, while the stabilizer bracket welds are potentially loaded only during a major seismic event.
| |
| MONITOR THE INCLUSION OF N-700 INTO REGULATORY GUIDE 1.147 OR DEVELOP AN ALTERNATIVE (SEE 3rd INTERVAL RR-41)
| |
| Item B10.20 - Piping: Per the Code, 10% of the piping welded attachments must be examined. There are 28 sets of welded attachments in the Class 1 scope. For the purpose of this discussion, a set is a group of welded attachments associated with a specific location. For instance, a hanger clamp may have four welded lugs but it is considered one set. When a set of welded attachments is selected for examination all of the welded attachments in that set should be examined.
| |
| 10% of 28 sets would require the examination of 3 sets of welded attachments.
| |
| Note: Containment penetrations are shown on FSAR Figure 3.8-2, sheets 1, 2 , and 3.
| |
| Sheets 1 and 2 are for flued head type penetrations; therefore, there are no attachments welded to the piping pressure boundary. Sheet 2, which applies to the Main Steam penetrations shows a welded attachment to the pressure boundary. These welded attachments are designated as 18PS on Figures A-6 and A-9 and are designated as 16PS on Figures A-7 and A-8. These four welded attachments are included in the total of 28.
| |
| Item B10.30 - Pumps: Per the Code, 10% of the welded attachments must be examined.
| |
| There are 3 Class 1 attachments on each of the two pumps requiring a total of one examination to be performed.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS Category B-L Pressure Retaining Welds in Pump Casings NA to Hatch.
| |
| Category B-L Pump Casings There are two Class 1 pumps at Hatch - the Recirculation System Pumps. The following 2001 Edition through the 2003 Addenda Code requirements apply.
| |
| : 1. If one of the two pumps is disassembled for maintenance or repair, a VT-3 examination of the accessible internal pressure boundary should be performed to the extent practical. Examinations are limited to one pump in the 10-year interval; therefore, if one of the two pumps is examined there are no other examination requirements for the 10-year interval.
| |
| : 2. There is not a requirement to disassemble a pump in order to perform the VT-3 examination.
| |
| : 3. There is not a requirement to completely disassemble a pump that has been partially disassembled for maintenance or repair. For a partially disassembled pump, examine the accessible portion of the internal pressure boundary.
| |
| : 4. If a pump has been partially disassembled and VT-3 examined and subsequently one of the pumps is disassembled such that a more extensive examination is allowed, re-perform a VT-3 examination on the disassembled pump.

| Category B-M Valve Body Greater Than 4 NPS Examinations (VT-3) are limited to one valve in each group of valves that are of the same size, constructional detail (e.g. globe), manufacturing method, and that perform similar functions in the system. The groupings are shown in Table 1-10.
| |
| : 1. If one of the valves in Table 1-5 is disassembled for maintenance or repair, a VT-3 examination of the accessible internal pressure boundary should be performed to the extent practical. Examinations are limited to one valve in the group in the 10-year interval; therefore, if one of the valves in a group is examined there are no other examination requirements for that group during the 10-year interval. Third Interval examinations are shown in Table 1-5.
| |
| : 2. There is not a requirement to disassemble a valve in order to perform the VT-3 examination.
| |
| : 3. There is not a requirement to completely disassemble a valve that has been partially disassembled for maintenance or repair. For a partially disassembled valve, examine the accessible portion of the internal pressure boundary (see Interpretation XI-1-01-12 below).
| |
| : 4. If a valve has been partially disassembled and VT-3 examined and later one of the valves in the same group is disassembled such that the coverage is significantly greater, perform a VT-3 examination on the recently disassembled valve.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS Category B-O - Pressure Retaining Welds in Control Rod Drive (CRD) Housings The bottom head of the RPV has a penetration for each CRD location. Each penetration has an Inconel SB-167 stub tube welded to the inside surface of the RPV bottom head with an Inconel 182 weld. Each CRD housing was raised into position inside the stub tube and fastened with a J-Groove weld to the stub tube. The J-Groove weld had an Inconel 82 root with the remainder Inconel 182. Outside of the RPV, there is a housing to flange weld and an intermediate housing to housing weld between the flange weld and the bottom of the vessel. (See Figure 2-BN-14-1 and A-29). The 2001 Edition with 2003 Addenda Code requirement is to perform a volumetric or surface examination of 10% of the welds located in the peripheral CRD housings. However, the examination is not required if the makeup flow specified in IWB-1220(a) is greater than the postulated loss of inventory caused by the failure of the weld. Per the Exemption Section of this document the makeup flow is 420 gpm and per Section 4.2.3.2.3.1 of the HNP UFSAR (shown below), the leak rate from the housing to flange weld failing in tension would be limited to ~ 840 gpm and the leak rate from a housing rupture would be ~ 1030 gpm.
| |
| Therefore, the examination is not exempt per Section XI because the makeup flow is insufficient. There are 36 peripheral CRD housings per Figure 2-BN-15-1; therefore two welds on four housings require examination. Each of the two welds outside of the RPV are stainless to stainless welds and may have some susceptibility to IGSCC dependent upon the degree of hydrogen water chemistry protection.
| |
| Weld Joining Flange to Housing Fails in Tension The failure considered is a crack in or near the weld that joins the flange to the housing.
| |
| This crack will extend through the wall and completely around the housing. The flange material is forged, Type 304 stainless steel, with a minimum tensile strength of 75,000 psi.
| |
| The housing material is seamless, Type 304 stainless-steel pipe, with a minimum tensile strength of 75,000 psi. The conventional full-penetration weld of Type 308 stainless steel has a minimum tensile strength approximately the same as that for the parent metal. The design pressure and temperature are 1250 psig and 575 0F, respectively. RPV pressure acting on the cross-sectional area of the CRD; the weight of the control rod, CRD, and flange; and the dynamic reaction force during CRD operation result in a maximum tensile stress at the weld of ~ 6000 psi. If the basic flange-to-housing joint failure occurs, the flange and the attached CRD are blown downward against the support structure. The support structure loading is slightly less than that for CRD housing failure because RPV pressure acts only on the CRD cross-sectional area. Lack of differential pressure across the collet piston causes the collet to remain latched and limit control rod motion to ~ 3 in.
| |
| Downward CRD movement is small; therefore, most of the CRD remains inside the housing. The pressure-under and pressure-over lines are flexible enough to withstand the small displacement and remain attached to the flange. RPV water follows the same leakage path described for the flange-bolt failure, except that exit to the atmosphere will be through the gap between the lower end of the housing and the top of the flange. Water flashes to steam in the annulus surrounding the CRD. The leakage rate is ~ 840 gal/min.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 1 COMPONENTS Class 1 Augmented Examinations The NRCs safety evaluation dated 6/16/97 of the 3rd Interval ISI Program indicated, that in addition to the 1989 Code required examinations, certain Class 1 augmented examinations would be performed per GPC commitment. The commitments along with the current implementation methodology are listed below.
| |
| : 1. Augmented examinations on the Unit 2 main steam, feedwater, HPCI (steam),
| |
| RCIC (steam) and RWCU high energy piping outside containment (where pipe breaks were not postulated) in compliance with Branch Technical Position MEB 3-1. Per Section 3.6.2.2.3 of the HNP-2 UFSAR, pipe breaks were not postulated in portions of high-energy piping extending from the containment penetration to the first inside and/or outside isolation valve for specified conditions. Therefore, for the above mentioned systems, volumetric exams are required on the welds between the inboard and outboard isolation valves to the extent practical. These examinations will be performed during the 4th Interval, to the extent practical.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 2 COMPONENTS SCOPE OF EXAMINATIONS Per IWA-1400 of the Section XI Code, the Owner is responsible for determining the appropriate Code Class, for identifying the system boundaries for each class of component subject to examination, and for identifying the components exempt from examination. This requirement is met by the following:
| |
| Appropriate Code Class The determination of the appropriate Code Class for each component is made by SNC Design Organization and designated on the ISI Boundary Diagrams. These Boundary Diagrams are controlled by SNC Design Organization.
| |
| System Boundaries The system boundaries for each Code Class are designated on the ISI Boundary Diagrams.
| |
| EXAMINATION REQUIREMENTS The examination requirements for the Class 2 components identified on the Boundary Diagrams are defined in IWC-2500 for each examination category. Categories are:
| |
| * Category C-A Pressure Retaining Welds in Pressure Vessels
| |
| * Category C-B Pressure Retaining Nozzle Welds in Vessels
| |
| * Category C-C Integral Attachments for Vessels, Piping, Pumps, and Valves
| |
| * Category C-F-2 Pressure Retaining Welds in Carbon or Low Alloy Steel Piping
| |
| * Category C-G Pressure Retaining Welds in Pumps The following Categories are not applicable to HNP.
| |
| * Category C-D Pressure Retaining Bolting Greater than 2 Diameter
| |
| * Category C-F-1 Pressure Retaining Welds in Austenitic Stainless Steel or High Alloy Steel Piping
| |
| * Category C-G Pressure Retaining Welds in Valves These examination requirements are not applicable to components exempt from examination per IWC-1220. Components exempt from examination are only subject to pressure testing requirements. (See the Exemptions Section below for more detail).
| |
| H2 Basis Doc - Class 2 Page 1 of 33 Rev. 1
| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 2 COMPONENTS EXEMPTIONS IWC-1220 defines the components that are exempt from the examination requirements of IWC-2500. Applicable Class 2 exemptions used during the 4th Interval include:
| |
| : 1. Size Exemption - All components less than or equal to 4 in diameter and their associated supports may be exempted from examination.
| |
| : 2. Pressure/Temperature Exemption - All components other than RHR, Emergency Core Cooling (ECC), and Containment Heat Removal (CHR) systems that operate at a pressure <
| |
| 275 psig and at a temperature < 2000F may be exempted from examination.
| |
| : 3. Open Ended Exemption - Components of any size beyond the last shutoff valve in open ended portions of systems that do not contain water during normal operation may be exempted.
| |
| The use of these three exemptions was evaluated and discussed below for application at HNP-2.
| |
| : 1. Size Exemption - For a BWR, the size exemption applies to all Class 2 components less than or equal to 4 in diameter.
| |
| : 2. Pressure/Temperature Exemption - This exemption applies only to Class 2 systems or portions of systems that do not have an RHR ECC, or CHR function. The RHR, ECC, and CHR function for HNP-2 is described below.
| |
| * Residual Heat Removal (RHR) Function - Per Section 5.5.7.3 of the UFSAR, portions of the RHR System are designed to remove decay and residual heat from the reactor core to achieve and maintain a cold shutdown condition. Therefore, the pressure/temperature exemption is not applied to these portions of piping.
| |
| * Emergency Core Cooling (ECC) Function - Per Section 6.3 of the UFSAR, four ECC subsystems protect the core against various sizes of hypothetical pipe breaks. Three subsystems inject emergency core cooling water into the reactor pressure vessel (RPV),
| |
| and one subsystem depressurizes the RPV. The three injection subsystems are Class 2 high-pressure coolant injection (HPCI), Class 2 low-pressure coolant injection - LPCI mode of RHR, and Class 2 core spray (CS). The fourth ECCS subsystem is the Class 3 automatic depressurization system. Therefore, the pressure/temperature exemption is not applied to these portions of piping.
| |
| * Containment Heat Removal (CHR) Function - Per Section 6.1 of the UFSAR, the containment heat removal system consists of the shutdown cooling and the suppression pool cooling modes of the residual heat removal (RHR) system for planned and abnormal operation, as well as the core spray (CS) system and the low-pressure coolant injection (LPCI) mode of RHR for accident mitigation. Therefore, the pressure/temperature exemption is not applied to these portions of piping.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 2 COMPONENTS
| |
| : 3. Open Ended Exemption The open ended exemption is applied to the following lines which normally do not contain water. Instead, they see a nitrogen atmosphere which is not conducive to cracking. The test lines and turbine exhaust lines were not included because they are subjected to quarterly pump testing. The relief valves discharge lines were conservatively not included because they could potentially have water in them.
| |
| * Figure B RHR Containment Spray piping from 2E11-F021A through the containment spray header. Includes welds 2E11-2RHR-16A-DS-10, 11, 12, 13, 14, and 15.
| |
| * Figure B RHR Torus Spray piping from MOV 2E11-F027A to the top of the Torus.
| |
| Includes welds 2E11-2RHR-6A-TSP-7, 8, 9, 10, and 11.
| |
| * Figure B RHR Containment Spray piping from 2E11-F021B through the containment spray header. Includes welds 2E11-2RHR-16B-DS-16, 17, and 18.
| |
| * Figure B RHR Torus Spray piping from MOV 2E11-F027B to the top of the Torus.
| |
| Includes welds 2E11-2RHR-6B-TSP-7, 8, 9, 10, and 11.
| |
| * Figure B Purge and Inerting piping from MOV 2T48-F308 to the containment penetration. Includes welds 2T48-2CPI-18-PID-1, 2, and 3.
| |
| * Figure B Purge and Inerting piping from MOVs 2T48-F310, 2T48-F309, and 2T48-F311 to the top of the Torus. Includes welds 2T48-2CPI-20-PIT-1 through 9 and welds 2T48-2CPI-18-PIT-8&9.
| |
| * Figure B Purge and Inerting piping from MOV 2T48-F319 to the containment penetration. Includes welds 2T48-2CPI-18-POD-1, 2, and 3.
| |
| * Figure B Purge and Inerting piping from MOV 2T48-F318 to the top of the Torus.
| |
| Includes welds 2T48-2CPI-18-POT-2, 3, and 4.
| |
| By system, the above exemptions were applied as follows:
| |
| : 1. 2C11 Control Rod Drive (CRD) System (See Boundary Diagram HB-26006 Sheets 1 and
| |
| : 2) - The Class 2 portion of this system is less than 4 in diameter and exempt from examination, except for the 8 Scram Discharge Header. In the March 5, 1982 response to NUREG-0803, it was stated in part, The headers are not exempted because of size, but are not presently included in Georgia Powers ISI weld examination program because they are rarely pressurized during normal operation, and then only to a pressure far below design pressure. This position has been continued through the 1st, 2nd, 3rd and 4th Intervals.
| |
| However, these welds do receive augmented exams per the March 5, 1982 letter, thus the 8 scram discharge header receives the same examinations as required by Code. The only difference is that the exams are augmented exams, not Code exams.
| |
| : 2. 2C41- Standby Liquid Control (SLC) System (See Boundary Diagram HB-26009). All components are exempt from examination because all piping is 4 NPS and less in diameter.
| |
| : 3. 2C71 Reactor Protection System (See Boundary Diagram HB-28001). All components are exempt from examination because all piping is 4 NPS and less in diameter.
| |
| H2 Basis Doc - Class 2 Page 3 of 33 Rev. 1
| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 2 COMPONENTS
| |
| : 4. 2E11 Residual Heat Removal (RHR) System (See Boundary Diagrams HB-26014&15) -
| |
| This system has ECC, CHR, and reactor residual heat removal functions; therefore, the pressure/temperature exemption cannot be applied. Exemptions are open-ended piping and the 4 NPS and less size exemption.
| |
| : 5. 2E21 Core Spray (CS) System (See Boundary Diagrams HB-26018&19). This system has ECC and CHR functions; therefore, the pressure/temperature exemption cannot be applied.
| |
| There is not any open-ended piping; therefore, the only exemption is the 4 NPS and less size exemption.
| |
| : 6. 2E41 High Pressure Coolant Injection (HPCI) System (See Boundary Diagrams HB-26020&21 and HB-26046). This system has an ECC function; therefore, the pressure/temperature exemption cannot be applied. It is SNCs position that the steam exhaust lines contain water; therefore, the open-ended exemption cannot be applied. The only exemption applied is the 4 NPS and less size exemption.
| |
| : 7. 2E51 Reactor Core Isolation Cooling (See Boundary Diagrams HB-26023&24 and HB-26046). Only a small portion of RCIC is classified as Class 2 per Boundary Diagram HB-26023, with the remainder designated as Class S (see augmented section). Per Section 5.5.6.1 of the UFSAR, the function of this system is to ensure that adequate core cooling takes place to prevent the reactor fuel from overheating in the event that reactor isolation is accompanied by loss of flow from the reactor feedwater system. This is not an RHR, ECC, or CHR function; therefore, all piping 4 and less in diameter is considered exempt from examination per IWC-1222(a) and all piping operating at a temperature equal to or less than 2000 F is considered exempt per IWC-1220(c). Non-exempt Class 2 RCIC piping is:
| |
| Welds 2E51-2RCIC-6-TS-3 through 10 on the 6 portion of piping from the Torus connection out to valve 2E51-F031. (Shown on Figure B-86). This piping is potentially subject to temperatures greater than 2000F during accident conditions; therefore, the pressure and temperature exemption cannot be applied. Since the size exemption and open-ended exemption cannot be applied, these 9 welds are not exempt. However, this is Class HLB, Schedule 40 piping which is less than 0.375 thick and not subject to examination, but is part of the total number of non-exempt welds.
| |
| The 6 portion of piping (welds 2E51-2RCIC-6-D-1&2) that connects the RCIC discharge to Class 2 Feedwater. (Shown on Figure B-66B). This system functions with the pressure above 275 psig and at a temperature greater than 2000F; therefore, the pressure and temperature exemption can not be applied. Since the size exemption and open-ended exemption cannot be applied, these two welds are not exempt.
| |
| H2 Basis Doc - Class 2 Page 4 of 33 Rev. 1
| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 2 COMPONENTS The 10portion of piping (2E51-2RCIC-10-TD-16A through 21) from the Torus connection out to valve 2E51-F040. (Shown on Figure B-82). This piping is subject to temperatures greater than 2000F; therefore, the pressure and temperature exemption cannot be applied. The open-ended exemption was not used because while the welds in question may not be under water the environment in the pipe is water or vapor. Since the size exemption and open-ended exemption cannot be applied, these welds are not exempt. However, this is Class HLB, Schedule 40 piping which is 0.365 thick and not subject to examination, but is part of the total number of non-exempt welds.
| |
| For the above listed Class 2 piping, only the 6 piping is subject to examination. The other welds are not subject to examination (but are listed in the total C-F-2 weld count) due to the wall-thickness; however, the associated component supports and welded attachments are subject to examination.
| |
| The remainder of the RCIC piping is designated as Class S (see Class 2 augmented).
| |
| : 8. 2G31 Reactor Water Cleanup (RWCU) System (See Boundary Diagram HB-26036). All components are exempt from examination because all piping is 4 NPS and less in diameter.
| |
| : 9. 2G41 Fuel Pool Cooling System (See Boundary Diagram HB-26039). There are no Class 2 components in the 2G41 system. The Class 2 inter-tie to RHR is shown on RHR drawing HB-26014.
| |
| : 10. 2G51 Torus Drain (See Boundary Diagram HB-26042) - This system provides no safety function except for a containment function. However, since it is connected to the Torus it may see an elevated temperature during accident conditions. The open-ended exemption cannot be used since the piping contains water and the piping is 8 so the size exemption cannot be used.
| |
| : 11. 2N11/2N37 Main Steam (MS) System (See Boundary Diagrams HB-21012 and the Class 2 portions of the Nuclear Boiler System Boundary Diagrams HB-26000, HB-26001, and HB-26189). This system functions with the pressure above 275 psig and at a temperature greater than 2000F; therefore, the pressure/temperature exemption cannot be applied. The only exemption applied to this piping is the 4 NPS and less size exemption.
| |
| : 12. 2N21 Feedwater System between the second and third feedwater check valve (See Nuclear Boiler System boundary Diagram HB-26000). This system functions with the pressure above 275 psig and at a temperature greater than 2000F; therefore, the pressure/temperature exemption cannot be applied. The only exemption applied to this piping is the 4 NPS and less size exemption.

| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 2 COMPONENTS
| |
| : 13. 2N22 Main Steam Drain Lines - Per page 12 of the SER [regarding MSIV Leakage Control System (LCS)], the licensee has committed to include the alternate LCS in the ASME Section XI inservice inspection program. The piping (drain line piping downstream of 2B21-F021 to the condenser) will be treated as ASME Code Section III, Class 2. Any repairs or replacement of this piping should also be performed in accordance with Section XI requirements. All of this piping is exempt per the 4 NPS and less size exemption.
| |
| : 14. 2P42 Reactor Building Closed Cooling Water (RBCCW) System (See Boundary Diagram HB-26055). Per Boundary Diagram HB-26055 the piping from the outboard isolation valve, the piping through the penetration, and the piping inside containment are designated as Class 2 because of the containment function. This piping provides cooling water to the reactor recirculation pump motor bearings inside containment. Per Section 9.2.2 of the UFSAR, the RBCCW system is not required to be operable following a LOCA.
| |
| This is not an RHR, ECC, or CHR function; therefore, the size exemption and pressure/temperature exemption may be used where applicable. Since the piping experiences low pressure and low temperature, both the size exemption and the pressure/temperature exemption may by applied. Therefore, all Class 2 RBCCW components are exempt from examination.
| |
| : 15. 2T48 Containment Purge and Inerting (See Boundary Diagram HB-26084 and HB-26083). This system allows the containment pressure to be controlled in case of a pipe rupture, allows any hydrogen buildup to be vented, and allows heat to be removed from the containment. Since heat may be removed from the containment by this system, it is considered as having a CHR function and the pressure and temperature exemption was not used. Much of this piping could be exempted using the open-ended exemption; however, only the size exemption was used during the 3rd Interval. The use of the open-ended exemption during the 4th Interval should be evaluated.
| |
| : 16. 2T45 Primary Containment Valve and Equipment Drainage System (See Boundary Diagram HB-26077). All components are exempt from examination because all piping is 4 NPS and less in diameter.
| |
| : 17. 2T49 Post LOCA Hydrogen Recombiner System (See Boundary Diagram HB-26068) -
| |
| This purpose of this was to maintain hydrogen levels below combustion levels during Post-LOCA conditions. Credit is not taken for this function; therefore, only the piping functioning as a Containment Isolation function will be considered. However, all of this piping may be exempted using the open-ended exemption.
| |
| : 18. Containment Isolation Piping. This piping is designated as Class 2 only because it penetrates containment and may have both the 4 exemption and the pressure/temperature exemption applied. The applicable containment penetrations, their function, the Boundary Diagram, and the size are listed below in Table 1:

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 2 COMPONENTS DEVIATIONS TO CLASS 2 ISI CODE REQUIREMENTS IWC-2500 provides the examination requirements for Class 2 components. These Code requirements may be deviated from by:
| |
| * The use of NRC approved alternatives to Code requirements per 10 CFR 50.55a(a)(3).
| |
| * The use of NRC approved Relief Requests per 10 CFR 50.55a(g)(6) when an examination requirement by the Code is determined to be impractical.
| |
| * The use of Code Cases approved for use by the NRC through publication in Regulatory Guide 1.147.
| |
| Significant deviations from IWC-2500 Code requirements at HNP-1 are:
| |
| (Note: See Volume 1 for listing of Relief Requests, Alternatives, and NRC Safety Evaluations).
| |
| Code Case N-663 Code Case N- 663 provides that ... in lieu of the surface examination requirements for piping welds of Examination Category C-F-1 and C-F-2 ,surface examinations may be limited to areas identified by the Owner as susceptible to outside surface attack. The susceptibility criteria are listed in Table 1 of Code Case N- 663 for two types of degradation mechanisms. No Class 2 welds have been identified as being susceptible to outside surface attack. The basis is discussed below:
| |
| External (O. D.) Chloride Stress Corrosion Cracking of Austenitic Stainless Steel NA - There is not any Austenitic Stainless Steel in Class 2 piping.
| |
| Other Outside Surface Initiated Mechanisms Per Code Case N-663, items that are susceptible to an outside attack should be identified by a plant-specific service history review. This review should include plant-specific processes and programs that minimize chlorides and other contaminants.
| |
| For carbon steel piping, chlorides are not a issue. During 30 years of Inservice Inspection of Class 2 components, outside attack of Class 2 components has not been identified.
| |
| Plant-specific processes and programs that minimize chlorides and other contaminants are:
| |
| The SNC Chemical Product Control Program provides procedure guidance for control of contaminants from chemical products to be used on site. Reference Hatch procedure 60 AC HPX-008-0, E. I. Hatch Chemical Control.

Per Table IWC-2500-1, Category C-A of the 1989 Code only the welds on one of the two heat exchangers need to be volumetrically examined. (Alternately the number of welds on one heat exchanger may be distributed over two heat exchangers). Welds to be volumetrically examined on the one heat exchanger include:
| |
| * Circumferential shell welds at a structural discontinuity (Item C1.10).

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 2 COMPONENTS Category C-B Nozzle Examinations in Class 2 Pressure Vessels 1st Interval Not Evaluated 2nd Interval The A outlet nozzle weld, the A nozzle inner radius, and the B Inlet nozzle weld were examined as shown in Interval 3 Table. The B Inlet nozzle inner radius was not examined because of an SNC interpretation that the configuration had a rounded corner instead of an actual inner radius configuration.
| |
| 3rd Interval There are two Class 2 vessels at Hatch - the RHR Heat Exchangers. Each RHR heat exchanger has one inlet and one outlet nozzle on each heat exchanger. The nozzles do not have reinforcement plates. For nozzles without reinforcement plates Table IWC-2500-1, Category C-B of the 1989 Code requires that only the nozzles on one of the two heat exchangers be examined. (Alternately the number of nozzles on one heat exchanger may be distributed over two heat exchangers). The nozzles initially selected for examination shall be re-examined over the life of the heat exchangers. Because of the pattern established in the 2nd Interval the A outlet nozzle and the B inlet nozzle will be examined. Examinations include surface and volumetric examinations of the two nozzle-to-shell welds and a volumetric examination of the inner radius volume on the two nozzles.
| |
| As discussed above in the 2nd Interval write-up, an interpretation was made that there was a rounded corner instead of an inner radius configuration. However, a 2004 review of drawings in manual S-25700 indicates that the configuration is similar to that shown in examination Figure IWC-2500-4(b) in the 1989 Code. While not exactly the same configuration, the Code figures are representative figures and it was not the intent of the Section XI Code to have an exact match of every configuration in the nuclear industry. While there is some debate as to the accuracy of the design drawing as compared to the actual configuration and there is additional debate regarding the ability to perform meaningful examinations, a somewhat more conservative approach was used for the 3rd Interval and the examinations were performed.
| |
| However, as shown in Table 4 below, the 3rd Interval examinations were performed significantly more than 10-years after the previous examinations. There was no cracking, so the structural integrity of the nozzle inner radii was verified for both the 2nd and 3rd Intervals. Therefore, there is not be a technical or safety issue. The basis for this determination is that since they were not cracked during 2R18, then they were not cracked during the 2nd Interval.

| 3rd Interval Table IWC-2500-1, Category C-C of the 1989 Code defines the examination requirements for Class 2 integrally welded attachments. In lieu of these requirements, HNP examines Class 2 welded attachments per the requirements of Code Case N-509, which was originally adopted for use at HNP through relief request RR-4. Relief Request RR-4 was superseded via the endorsement of Code Case N-509 in Revision 12 to Regulatory Guide 1.147. Revision 13 subsequently annulled the Code Case; however, it may be used until the end of the 3rd interval.
| |
| Revision 12 had a condition for use, in that, at least 10% of each Item No. was required to be examined (for those items not already requiring 100%). Each Class 2 Code Case N-509 Item is discussed below.
| |
| Code Case N-509, Item C3.10 - Pressure Vessels - As shown in Table 6, the only Class 2 pressure vessels are the two RHR Heat Exchangers. With multiple vessels, Code Case N-509 allows the examination of one of the welded attachment on one of the vessels. 2E11\2HX-A-2S-4 was examined in the 1st Period (2R14).

| |
| : 2. The Code indicates in Table IWC-2500-1, Category C-F-2, Footnote 2 that some welds that are not exempted by IWC-1220 are not required to be examined, because they are less than 3/8 (0.375) thick, but they are required to be included in the total weld count to which the 7.5% sample will be applied. Per the Code Compliance Scheduling Summary for C-F-2 welds there are 1170 welds in the population, requiring 88 examinations. For Category C-F-2, not all of the roundup will be used because the welds were broken out by system in order to facilitate the implementation of (the below listed) proration requirements. Allowing all of the roundup would require an excess number of examinations. Additionally, there is not a Code requirement to meet the 7.5% percentage requirements for each Code Item, but only for the total category C-F-2 welds. Using the below listed proration requirements the Code requirements will be met. (Note: 94 welds were selected.)

| |
| Table IWC-2500-1, Category C-G of the 2001 Edition of Section XI with Addenda through 2003 defines the examination requirements for these welds. For pump welds, the Code requires that in the case of multiple pumps of similar design, function, and service in a system, only the pressure retaining welds on one pump needs to be examined. As shown in Table 16 for Interval 4, Hatch has four Class 2 RHR pumps and two Class 2 Core Spray pumps that have pressure-retaining welds. The welds in RHR Pump A and Core Spray Pump A are scheduled for examination during the 4th Interval as shown in Schedule Works.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 2 COMPONENTS AUGMENTED EXAMINATIONS The NRCs safety evaluation dated 6/16/97 of the 3rd Interval Program listed several augmented programs that will be maintained during the 4th Interval.
| |
| NUREG-0803 The NRCs safety evaluation dated 6/16/97 of the 3rd Interval Program indicated, that in addition to the Code required examinations, the examination of the Scram Discharge Volume (SDV) piping in accordance with NUREG-0803 would be examined. NUREG-0803 contends that since the SDV was designed and fabricated in accordance with Class 2 piping that it should be subjected to the ISI requirements for Class 2 piping. By letter dated March 5, 1982 GPC committed to the following, We will include weld examination of the SD (scram discharge) headers in the ISI program ..
| |
| The 2nd Interval update was performed effective 12/31/85 and these welds were included as required. As permitted in 10CFR50.55a, examination locations were selected by the 1974 Code with addenda through Summer 1975 and the examinations were performed per the 1980 Edition of Section XI through Winter 1981. As shown on ISI Figures B-84 and B-85 there are thirty-three (EBB, 0.5 thick, schedule 80 carbon steel), welds.
| |
| The 1974 Code required examination of 100% of welds that circulate reactor coolant to be examined over the 40-year life. For those systems not circulating reactor coolant the examinations could be reduced to 50% of the welds. These welds are outside the Reactor Coolant Pressure Boundary and per NEDO-24342, GE Evaluation in Response to NRC Request Regarding BWR Scram System Pipe Breaks they are pressurized less than 1% of the time.
| |
| Therefore, these welds were designated as not circulating Reactor Coolant. Additionally, because there are two similar CRD headers only the equivalent of 50% of one the headers needed to be examined during the 40-years. Since the largest header has 18 welds, 50% or nine welds have to be examined during the 40-year life or three welds per 10-year interval. The 1980 Code required a surface examination technique for 0.5 thick piping.
| |
| For the 3rd Interval, a 7.5% sample (3 welds) were volumetrically examined. The 1989 Code requirement to perform both a volumetric and surface examination was not followed for this augmented requirement, since RR-40 was issued to eliminate piping surface examinations.
| |
| Welds and examinations are shown in Table 17. (Note: Two welds had a surface examination during the 3rd Interval, but were not counted toward this requirement). Code credit (i.e., C-F-2) was not taken for these examinations.
| |
| For the 4th Interval, a 7.5% sample (volumetric) is required. Welds and examinations are shown below in Table 17. This piping is designated as Class 2S in Schedule Works.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 2 COMPONENTS AUGMENTED EXAMINATIONS Thin-Wall Piping The NRCs safety evaluation dated 6/16/97 of the 3rd Interval Program also indicated, that in addition to the 1989 Code required examinations, volumetric examination of a 7.5% sample of a portion of thin-wall, non-exempt piping within the RHR, CS, and HPCI systems would be performed. Per Table IWC-2500-1, Category C-F-2 only carbon steel welds 3/8 (0.375) thick require examination; however, SNC agreed to volumetrically examine a 7.5% sample of the welds in this thin wall piping. The Class 2 augmented section of the 3rd Interval ISI Program indicates that the portion of thin-wall, non exempt piping subject to examination is:
| |
| : a. The thin-wall piping on the downstream side of pumps whose integrity is needed to maintain the pressure boundary for the system to perform its intended RHR, ECC, or CHR safety function.
| |
| : b. The Branch connection piping out to the first normally closed valve, or to the first valve capable of automatic closure, or to a flange when the piping downstream of the valve or flange has a non-ECCS, non-RHR, or non-CHR function.
| |
| Per pipe schedule tables, this thin wall piping is limited to Schedule 40 (or thinner) piping 6, 8, or 10 in diameter. Table 18 shows the Class 2 welds in the thin wall scope and defines the welds that meet criteria a or criteria b. There are approximately 75 welds that meet criteria a or criteria b; therefore, at least six welds are required to be examined to meet the 7.5% requirement.
| |
| For the 4th Interval, a 7.5% sample (volumetric) is required. As shown in Table 18 six welds were selected. Code credit (i.e., C-F-2) was not taken for these examinations.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 2 COMPONENTS AUGMENTED EXAMINATIONS Portions of the Reactor Core Isolation Cooling are designated as Class S on Boundary Diagrams H-26023 and H-26024. Because this piping has importance, it will be treated using Section XI as a guideline (not as a requirement). As discussed for the Class 2 portion of this piping, this system does not have an RHR, ECC, or CHR function; therefore, the size exemption and pressure/temperature exemption will also be used for this Class S piping. Lines within Class S are evaluated below for examination potential.
| |
| 8 and 10 Steam Exhaust (Figure B-82) - This 8 and 10piping is not pressure temperature exempt because of the steam conditions and it is not size exempt. However, all of this HBB piping is 0.365 (.322 for the 8 weld) nominal wall thickness and therefore does not require examination of the piping welds. The five welded attachments on this line are subject to Category CC type examinations are shown in Table 19. They are designated as Category CC-R in Schedule Works.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 3 COMPONENTS Scope The only Class 3 ISI examinations required by IWD are the examination of integrally welded attachments (of supports and restraints) to the pressure boundary of Class 3 piping and components. Class 3 piping and equipment are defined on the HNP-2 Boundary Diagrams listed below:
| |
| HB-21033 Plant Service Water HB-21035 Plant Service Water HB-21039 RHR Service Water HB-26000 Main Steam Relief Valve Lines HB-26019 Jockey Pump Seal Cooling HB-26046 Condensate Transfer HB-26050 Plant Service Water HB-26051 Plant Service Water For the 4th Interval, examinations are performed in accordance with IWD-1000 of the 2001 Edition of Section XI with Addenda through 2003. Therefore, the examination scope shall apply to Class 3 systems piping and equipment that support the following safety functions:
| |
| : 1. Reactor shutdown
| |
| : 2. Emergency core cooling
| |
| : 3. Containment heat removal
| |
| : 4. Atmosphere cleanup
| |
| : 5. Reactor residual heat removal.
| |
| : 6. Spent fuel pool residual heat removal.
| |
| Exemptions Per IWD-1220 not all of the integrally welded attachments are subject to examination -
| |
| some are exempt from the examination requirements. These are:
| |
| * Integral attachments of supports and restraints on piping that are NPS 4 and smaller.
| |
| * Integral attachments of supports and restraints on vessels, pump, and valves and their connections in piping NPS 4 and smaller.
| |
| * Integral attachments located on components in systems (or portions of systems) whose function is not required in support of reactor residual heat removal, containment heat removal, and emergency core cooling and that operate at a pressure equal to or less than 275 psig and at a temperature equal to or less than 2000F.
| |
| * Integral attachments that are inaccessible due to being encased in concrete, buried underground, located inside a penetration, or encapsulated by guard pipe.

| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN CLASS 3 COMPONENTS Plant Service Water (PSW) Evaluation Equipment required to be cooled during emergency conditions by PSW includes:
| |
| : 1. HB-21033 describes the Class 3 intake structure Division I and Division II Supply Piping. This is the source of all safety-relate PSW water to the essential components and thus must be included. All of the Class 3 piping is in the examination scope for welded attachments except for 4 and under piping. The 18 discharge from the PSW pumps and the Division I and Division II 30 headers are shown on C-29. C-28 shows the 30 Division I and II supply lines to the point where they go underground..
| |
| Also shown is the 30 dilution line out to MOV F310 (Class 0 beyond this valve).
| |
| After going underground, an 8 supply line from the 30 Division I supply line enters the Diesel Generator Building through the floor and supplies cooling water to Diesel Generator 2A as shown on C-46. Similarly, an 8 supply line from the 30 Division II supply line enters the Diesel Generator Building through the floor and supplies cooling water to Diesel Generator 2C as shown on C-46. C-45 shows the 6 return lines from the two diesel to the building floor.
| |
| The 6 Standby Diesel Service Water from the pump to the point it goes underground is shown on C-39. The 6 pipe from the Diesel Generator Building wall (coming from the underground piping) to the HNP-1 Diesel Generator 1B is shown on C-37.
| |

| : 2. HB-21035 shows a small portion of 6 line that is a header for the discharge side of the Essential LPCI Inverter Room Coolers. This header turns into Seismic II; therefore, this piping is not safety-related. (Note: H-26904 indicates that the PSW is Seismic I on the inlet side of the Inverter Room coolers).
| |
| : 3. Per HB-26039 (Note 5) there is an NRC commitment to maintain a certain portion of fuel pool cooling piping as Class 3. Per HB-26039 and HB-26050 this is the piping that functions as the fuel pool makeup source from the Plant Service Water system. It includes the piping from Plant Service Water to the point downstream of 2G41-F054 where it becomes imbedded in concrete. This piping is shown on C-17B.
| |
| : 4. HB-26050 describes the cooling water supply to equipment in the reactor building.
| |
| This 10 supply enters the reactor building through the wall from Division I underground piping as shown on C-49. The line branches into a 8 line to fire protection which terminates at valve F109 and it branches to a 6 line which continues on C-32 to a 4 reducer. The 10 line ties continues from C-49 to C-17.
| |
| On C-17 there is a 10 intertie to Division II (See C-15), a 10 supply to C-17A, a 4 fuel pool make up line that continues on C-17B, and an 8 supply to C-23. The intertie to Division II is described below. On C-17A the 10 line goes though P41-F074 and terminates at a cap. The 8 supply line on C-23 provides cooling water to the drywell coolers. C-23 also shows the return lines which continue on C-23a and terminate on C-23B where the piping goes underground just past P41-F063. Note:

| RHR Service Water Evaluation HB-21039 describes the Class 3 intake structure Division I and Division II Supply Piping. The piping is in the examination scope for welded attachments except for 4 and under piping. C-2 and C-3 show inlet piping to RHR Heat Exchanger B001A. C-4 and C-5 show inlet piping to RHR Heat Exchanger B001B. C-7 and C-8 show outlet piping for RHR Heat Exchanger B001A and B001B, respectively. C-9, C-10, and C-11 show the RHR Service Water Pumps and the associated piping in the intake structure.
| |
| Main Steam Relief Piping Evaluation HB-26000 describes the Main Seam relief Valve piping. Isometric Sketches C-109 through C-124 show the scope of the Class 3 portion of the Main Steam Relief valve piping (supports reactor shutdown). Because of the temperature at which they operate, the pressure and temperature exemption cannot be used. All piping is greater than 4 in diameter thus all welded attachments are in the examination scope.
| |
| Fuel Pool Makeup Water HB-26039 indicates that the Fuel Pool Cooling and Cleanup System is out of the ISI scope (designated as Class 0 on the Boundary Diagram). Instead, an Emergency Makeup source is maintained through the Plant Service Water system.

| |
| : 1. The integrally welded attachments are located in systems (or portions of systems) that are shown on the referenced Boundary Diagrams, and
| |
| : 2. the system or portions of systems perform the listed safety functions, and
| |
| : 3. they are not exempt.
| |
| Each Category D-A Item is discussed below.
| |
| Item D1.10, D1.30, & D1.40 None Identified.
| |
| Item D1.20 - Piping As shown in Schedule Works, Hatch 2 has 133 sets of Class 3 welded attachments.
| |
| Footnote 3 requires a 10% sample; therefore, 14 sets of welded attachments require examination The cumulative examination percentages meet the requirements of Table IWD-2412-1.
| |
| Additionally, examination of an integrally welded attachment is required if the associated component support member has deformation identified during operation, refueling, maintenance, examination, inservice inspection, or testing. An example of component support deformation is broken parts, bent parts, or pulled out parts.

| |
| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN COMPONENT SUPPORTS SCOPE For the 4th Interval, the determination of the Class 1, 2, and 3 supports to be examined will be performed using Subsection IWF of the 2001 Edition of Section XI through the 2003 Addenda. (The rules in IWF are similar to those used during the 3rd Interval per NRC approved Code Case N-491-1). (Note: IWE supports are not included here).
| |
| Per the IWA-9000 Glossary a component support is defined as a metal support designed to transmit loads from a component to the load-carrying building or foundation structure. Component supports include piping supports and encompass those structural elements relied upon to support the weight or provide structural stability to components.
| |
| Examinations apply to all component supports that are in the scope of the Class 1, 2, and Boundary Diagrams and are not exempt. Supports exempt from examination requirements are those connected to piping or other items exempted from volumetric, surface, VT-1, or VT-3 examinations by IWX-1220. In addition, portions of supports that are inaccessible by being encased in concrete, buried underground, or encapsulated by guard pipe are also exempt from the examination requirements of IWF-2000.
| |
| Component supports should be selected for examination as follows:
| |
| : 1. Supports should be characterized to identify its support type/function. For HNP-2, the support type/functions include the following:
| |
| Spring Cans - Supports weight while allowing movement due to thermal changes.
| |
| Hanger - Supports the weight of the piping system.
| |
| Restraint/struts - Prevents movement of the piping system in one or more degrees of motion.
| |
| Anchors - Prevents movement in all six degrees of motion.
| |
| : 2. 25% of the non-exempt Class 1 piping supports, 15% of the non-exempt Class 2 piping supports, and 10% of the non-exempt Class 3 piping supports shall be examined per Table IWF-2500-1.
| |
| : 3. The supports selected for examination shall be prorated such that the individual sample sizes for each system are proportional to the number of non-exempt supports in each system.
| |
| : 4. For multiple components other than piping, within a system of similar design, function, and service, the supports of only one of the multiple component are required to be examined.

| | |
| HATCH UNIT 2 FOURTH INTERVAL ISI PLAN COMPONENT SUPPORTS ISI PLAN TABLES Beginning in 2005, ISI Plan Tables are generated by the industry standard ScheduleWorks ISI software. The following tables were generated using a standard format provided by ScheduleWorks. It should be noted that the Scope/Method/Procedure field is for information only. This information may be changed during an outage by IDDEAL users at the site, but it will not be reflected in the ISI Plan until the plan is issued after the outage.
| |
| When using these tables the user needs to understand the following symbols:
| |
| Scheduled "s" To schedule a component, place the identifier "s" in the required period/outage.
| |
| Completed "c" Upon exam completion for a scheduled component and by uploading the outage scope from IDDEAL back to ScheduleWorks, an "s" will be updated to completed "c".
| |
| Re- "r" Once a component has been scheduled, and you wish to reschedule to another outage, replace the scheduled scheduled "s" with a rescheduled "r" and enter an "s" in the new outage schedule.
| |
| Expanded "e" To increase a work scope without taking code credit in the percentage calculations, enter an Scope expanded "e".
| |
| Expanded "E" Upon exam completion of an expanded scope and by either uploading the outage scope from Scope IDDEAL or manually changing the letter to an upper case "E" the exam scope is completed.
| |
| Completed Additional "a" After an initial expanded work scope has been identified and you wish to add an increased Scheduled expanded work scope, enter an additional expanded scope "a".
| |
| Additional "A" Upon exam completion of an additional expanded scope and by either uploading the outage scope Completed from IDDEAL or manually changing the letter to an upper case "A" the exam scope is completed.
| |
| Partial "p" To track partially completed component examination requirements enter a partial "p".
| |
| Deferred "d" Once a component has been scheduled, and you wish to defer the inspection to another Outage, or Period, replace the scheduled "s" with a deferred "d" and enter an "s" in the new Outage.
| |
| Limited "l" To track limited component examinations or limited completions of requirements enter "l".
| |
| Multiple "b For multiple scheduling of the same component in successive Outages or Periods within an Interval Scheduled enter "b".
| |
| Multiple "B" Upon exam completion of a multiple scope in the same Interval and by either uploading the outage Completed scope from IDDEAL or manually changing the letter to an upper case "B" the exam scope is completed. This multiple scheduling scope will not count as completed for code calculations.
| |
| Tickler "t" To track exam scopes or use as reminder or identifier to confirm scheduling enter "t".
| |
| Successive "h" Successive examinations.
| |
| Exams Successive "H" Upon exam completion of a successive scope and by either uploading the outage scope from Exams Com IDDEAL or manually changing the letter to an upper case "H" the exam scope is completed.

| | |
| HATCH UNIT 1 FOURTH INTERVAL ISI PLAN COMPONENT SUPPORTS EXAMINATION OF SNUBBERS IWF-1220 of the 2001 Edition of Section XI with Addenda through 2003 requires that the inservice inspection requirements for snubbers be in accordance with the requirements of IWF-5000, which states:
| |
| (a) Inservice examinations shall be performed in accordance with ASME/ANSI OM, Part 4, using the VT-3 visual examination method described in IWA-2213.
| |
| (b) Inservice tests shall be performed in accordance with ASME/ANSI OM, Part 4.
| |
| 10 CFR 50.55a(b)(3)(v) provides an alternative to these two requirements. Licensees may use Subsection ISTD, "Inservice Testing of Dynamic Restraints (Snubbers) in Light-Water Reactor Power Plants," ASME OM Code, 1995 Edition through the 2003 Addenda, in place of the requirements of IWF-5300(a) and (b) by making appropriate changes to their technical specifications or licensee-controlled documents (if required).
| |
| Inservice examinations must be performed using the VT-3 visual examination method described in IWA-2213.
| |
| However, per IWF-5300(c) integral and non-integral attachments for snubbers including bolting, pins, and clamps, shall be examined in accordance with the requirements of this Subsection (IWF). (Attachments to the pressure boundary such as lugs will be examined per Category B-K, C-C, or D-A). IWF allows a percentage of the integral and non-integral attachments for snubbers to be examined as follows:
| |
| Attachment welds will be examined in accordance with IWB, IWC, or IWD.
| |
| The snubber unit including the pins that secure the snubber unit into the support structure will be examined as required by OM requirements.
| |
| The support structure (bolting, pin, and clamps outside of the snubber unit), will be VT-3 examined and reported as required by IWF. Therefore, for Class 1 snubbers, 25% of the support structures will be scheduled and VT-3 examined; 15% of the Class 2 support structures will be scheduled and VT-3 examined, and 10% of the Class 3 support structures will be scheduled and VT-3 examined. For non-piping snubbers, Footnote 3 of Table IWF-2500-1 must be used to determine the scope.
| |
| Personnel performing the VT-3 examinations may be qualified and certified per IWA-2310 through IWA-2314 (the standard qualification/certification process) or per IWA-2317. IWA-2317 allows the use of plant personnel with at least 40 hours of plant experience in installation, maintenance, or examination of pumps, valves, and supports to perform the VT-3 examinations. These personnel must have 8 hour of training in the Section XI requirements and procedures for VT-3 visual examinations, meet the vision test requirements of IWA-2321, have an initial exam, and have a followup exam every three years. If using these alternate requirements they shall be described in the appropriate written practice. (Note: The official list of snubbers is shown in HNP site procedures 52SV-SUV-001-0S and 52SV-SUV-002-0S).

| HATCH UNIT 1 FOURTH INTERVAL ISI PLAN COMPONENT SUPPORTS Determination of Class 1 Piping Supports to be Examined Per IWF-1230 supports exempt from examination are those connected to piping and other items exempted from examination by IWB. These include supports on lines:
| |
| NPS 1 and smaller for Schedule 80 and Schedule 160 water lines.
| |
| NPS 2and smaller for Schedule 80 steam lines and NPS 2.5 for Schedule 160 steam lines.
| |
| Per Schedule Works there are 80 Category F-A, Item F1.10 piping supports, plus 39 Item F1.10N supports on small diameter lines that were that were exempt during the 3rd Interval. The N designation was used for the new supports added during the 4th Interval. It should be noted that, in many cases, the HNP-2 design isometric drawing shows a containment penetration as being an anchor point for the purpose of stress analysis because it is a rigid point. This anchor is not labeled except for the penetration number and it is not a component support.
| |
| Table IWF-2500-1, Category F-A, Item F1.10 requires that 25% of the (80 + 39) non-exempt Class 1 supports be examined (30 supports). Additionally, per Footnote 2 of Table IWF-2500-1, the examinations should be prorated among the Class 1 systems based on the number of supports shown for each system versus the total number of non-exempt supports. These proportional values are listed below for each Class 1 system and are shown as exact values only to eliminate the compounding of round-up/down errors.
| |
| The number examined for each system may have a slight variance from the prorated number as long as the 30 examinations were performed.

While the examination of the snubber unit is performed per OM, not Section XI; the remainder of the support is effectively examined the same as any other support. As shown in the table below, there are 54 snubbers in the Class 1 piping systems; therefore, 14 require examination per Section XI. The snubbers to be examined are prorated through the Class 1 piping systems as shown below.

| |
| * Supports located on components in systems (or portions of systems) whose function is not required in support of reactor residual heat removal, containment heat removal, and emergency core cooling and that operate at a pressure equal to or less than 275 psig and at a temperature equal to or less than 2000F. (Reference Class 2 portion of this document for IWB-1220 exemptions used at HNP-2).
| |
| * Supports located on components of any size beyond the last shutoff valve in open ended portions of systems that do not contain water during normal operation.
| |
| (Reference Class 2 portion of this document for IWB-1220 exemptions used at HNP-2).
| |
| Portions of supports that are inaccessible by being encased in concrete, buried underground, or encapsulated by guard pipe.
| |
| Per Schedule Works there are 326 non-exempt Category F-A, Item F1.20 piping supports (excluding snubbers). It should be noted that, in many cases, the HNP-2 design isometric shows a containment penetration, torus penetration, pump nozzle, etc. as being an anchor point for the purpose of stress analysis because it is a rigid point. This anchor is not labeled except for the penetration number and it is not a component support.
| |
| Table IWF-2500-1, Category F-A, Item F1.20 requires that 15% of the 326 non-exempt Class 2 supports (or 49) be examined. Additionally, per Footnote 2 of Table IWF-2500-1, the examinations should be prorated among the Class 2 systems based on the number of supports shown for each system versus the total number of non-exempt supports. These proportional values are listed below for each Class 2 system and are shown as exact values only to eliminate the compounding of round-up/down errors. The number examined for each system may have a slight variance from the prorated number as long as the 49 examinations were performed.

| HATCH UNIT 1 FOURTH INTERVAL ISI PLAN COMPONENT SUPPORTS Determination of Supports Other Than Piping to be Examined Per Schedule Works there are 62 non-exempt Category F-A, Item F1.40 equipment supports. These 62 supports are shown in the below listed table. Table IWF-2500-1 requires the examination of each equipment support except when there are multiple components within a system that have a similar design, function, and service. For this case, Note 3 of Table 2500-1 indicates that only the supports on one of the similar components needs to be examined. For example each of the two RC pumps has three supports for a total of six supports. Only three of the supports are required to be examined. The examination selection is listed in the table shown below.
| |
| The support structure around each RPV stabilizer brackets was not included as a support, because there are no loads transmitted to them unless there is movement of the RPV due to a significant seismic event. They are considered analogous to pipe whip restraints which are not included as supports (See Interpretation XI-80-02).

| |
| Section XI, Division 1, IWF-1100, Examination of Pipe Restraints Question: Does Section IX, Division 1, IWF-1100 exclude pipe whip restraints from the inservice inspection requirements of Subsection IWF?
| |
| Reply: The scope of IWF is limited to those supports which are required to be constructed in accordance with Subsection NF. Since pipe whip restraints are exempt from the requirements of NF, they are also exempt from the requirements of IWF.
| |
| The Recirculation Pumps are the only Class 1, 2, or 3 equipment that has snubbers.

| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 SCOPE This report describes the revised inspection criteria for stainless steel and dissimilar metal weld piping subject to Generic Letter 88-01, NRC Position on Intergranular Stress Corrosion Cracking in BWR Austenitic Stainless Steel Piping requirements based on the revised criteria in BWRVIP-075. Included are new inspection frequencies and new sample expansion criteria.
| |
| BACKGROUND Due to extensive Intergranular Stress Corrosion Cracking (IGSCC), the stainless steel piping for the Recirculation System, the RHR System, and the RWCU System was replaced with IGSCC resistant 316NG material during the mid-1980s. However, components such as the stainless steel RPV safe-ends and the RWCU containment penetration piping were not replaced. Each of the welds (where the configuration allowed) was subsequently stress improved to reduce the tensile residual stresses at the weldment inside surface. An inspection program was set up per the requirements Generic Letter 84-11 which was subsequently superseded by Generic Letter 88-01 (GL 88-01), NRC Position on Intergranular Stress Corrosion Cracking in BWR Austenitic Stainless Steel Piping and NUREG-0313, Technical Report on Material Selection and Processing Guidelines for BWR Coolant Pressure Boundary Piping. Inspection Categories were established based on GL 88-01 requirements. GL 88-01 Categories currently applicable to HNP-2 are:
| |
| Category A - Welds are made from materials that are resistant to IGSCC due to their metallurgical properties. As such, the current required inspection scope and frequency per GL 88-01 is 25% of the population every 10 years.
| |
| Category C - Welds are made from material that is considered susceptible to IGSCC, but the IGSCC was mitigated by stress improvement after more than two cycles of operation.
| |
| GL 88-01 specifies that the entire population is to be examined once every ten years.
| |
| Category D - Welds are those made of susceptible material that have not been treated with an IGSCC remedy and in which cracks have not been reported. GL 88-01 specifies that all welds be examined every two refueling cycles.
| |
| Category E- Welds that have been overlayed with IGSCC resistant material. GL 88-01 specifies that all overlays be examined every two refueling outages.
| |
| Because of improved water chemistry that significantly reduced the propensity for initiation and growth of IGSCC, and due to improved examination procedures/techniques for the detection and sizing of IGSCC, new inspection criteria were proposed in BWRVIP-075 and subsequently accepted by the NRC for each of these categories. This report describes the revised inspection criteria for Category A, Category C, Category D, and Category E piping subject to GL 88-01 requirements based on the revised criteria in BWRVIP-075. Included are new inspection frequencies and new sample expansion criteria. Table 1 lists key dates Hatch 2 Basis Doc-VIP75.doc Page 1 of 40 Rev.1.0

| |
| Table 1 Transition From GL-88-01 To BWRVIP-05 DATE ITEM 6/23/2000 HNP requested the use of BWRVIP-075 in lieu of GL 88-01 and requested an alternative to Code requirements to allow reduced B-J and B-F Code requirements.
| |
| 10/10/2000 The NRC issued a safety evaluation for the HNP request allowing HNP a one cycle use of BWRVIP-075 in lieu of GL 88-01 and Code relaxation from B-F (100%) and B-J (25%) provided that surface examinations were performed.
| |
| 10/2000 The NRC issued a safety evaluation (with caveats) allowing the use of BWRVIP-075 in lieu of the existing GL 88-01 requirements. The NRC noted that the safety evaluation could be used as a reference for a 10CFR50.55a alternative to reduce Code exams for welds in GL 88-01 scope.
| |
| 6/2001 Structural Integrity Associates issues Weld Prioritization for Adoption of BWRVIP-075 at Edwin I. Hatch Unit 1 and Unit 2.
| |
| 5/2002 The NRC issues the final BWRVIP-075 safety evaluation after evaluation of BWRVIP responses to open items.
| |
| 4/2003 The BWRVIP issues the initial draft A-Version of BWRVIP-075 to incorporate the NRCs comments in their final safety evaluation.
| |
| 2004 SNC seeks approval in RR-39 to reduce the Code exams associated with this piping.
| |
| 7/2005 NRC grants approval of RR-39.
| |
| 10/2005 BWRVIP-75-A Final report issued.
| |
| 12/2005 NRC grants approval of ISI-ALT-3 to continue during the 4th Interval with the alternatives originally set forth in RR-39.
| |
| 3/2006 NRC issues approval letter for BWRVIP-75-A.
| |
| 4/2006 EPRI issues letter from Robin Dyle/Tom Mulford regarding inspection relief for hydrogen water chemistry.
| |
| VIP-75 IMPLEMENTATION The NRC issued a final Safety Evaluation for BWRVIP-075 dated May 14, 2002 with several comments. Subsequently, the BWRVIP developed a draft version of BWRVIP-075-A to incorporate the NRC comments and this document was found acceptable by NRC letter dated March 16, 2006.
| |
| This bases document is based on BWRVIP-75-A dated October 2005.

| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 The sample size required to be examined by BWRVIP-075-A is smaller than that required by ASME Section XI. Therefore, ISI-ALT-3 was submitted to the NRC and subsequently approved by an NRC Safety Evaluation dated 12/22/05. This request allows the use of the new sample sizes specified in BWRVIP-075 as an alternative to 10 CFR 50.55a and Section XI Code requirements for Category B-J and B-F welds.

| Evaluation of OE22809- Operating Experience where Perry GL 88-01 Exams Were Not Performed Within Required Frequency. Dated 6/19/2006 Upon receipt of a letter from the Boiling Water Reactor Vessel and Internals Project (BWRVIP) alerting utilities that they should ensure that generic inspection relief for Hydrogen Water Chemistry is not being taken, the implementation of Generic Letter (GL) 88-01 inspection schedules, as modified by EPRI Technical Report TR-113932, "BWR Vessel and Internals Project Technical Basis for Revisions to Generic Letter 88-01 Inspection Schedules (BWRVIP-75)," was reviewed by Perry and it was found that a GL 88-01 Category E weld had been erroneously put on a 10 year schedule rather than the required six year schedule. Examination of the weld by the six year point was missed.
| |
| Discovery of this scheduling error resulted in a full review of the scheduling for GL 88-01 exams. The review found that GL 88-01 Category C weld examinations, identified as having an "every 10 years" frequency in GL 88-01 and BWRVIP-75, had been incorporated into Perry's augmented Inservice examination program on a "10-year interval" frequency consistent with normal ASME Section XI scheduling. That is, they were scheduled to meet Section XI successive examination requirements, which allow for extension by as much as a year to enable an inspection to coincide with an outage. As such, some Category C welds were not examined by the 10 year point, which was in-between refueling outages, and thus did not meet a literal interpretation of "every 10 years."
| |
| SNC Position - SNC has specific relief as defined in Appendix B of this document.
| |
| Regarding the "every 10 years" versus the "10-year interval" frequency, Robin Dyle who is the author of BWVIP-075 stated that it was his intent to use a 10-year interval frequency as defined in Section XI. Therefore, the length of time to perform an examination can be up to 11 years if needed to coincide with a scheduled outage.

| | |
| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 Review of SNC Scheduling Table 2 includes 67 Category A welds with hydrogen water protection. A 10% sample was used; therefore, 7 welds were selected and will be examined on a 10-year interval frequency. Three welds were examined in Spring 2000 and will be re-examined Spring 2009; one weld was examined in Spring 2003 and will be re-examined in 2009; and three welds were examined in Spring 2005 and will be re-examined in Spring 2015.
| |
| Table 3 includes 12 Category C welds without effective hydrogen water chemistry. A 25%
| |
| sample was used; therefore 3 welds were selected and will be examined on a 10-year interval frequency. Two welds were examined in Spring 2000 and will be re-examined in Spring 2009. One weld was examined in Spring 2005 and will be re-examined in Spring 2015.
| |
| Table 4 includes 12 Category C welds with effective hydrogen water chemistry. A 10%
| |
| sample was used; therefore 2 welds were selected and will be examined on a 10-year interval frequency. Two welds were examined in Spring 2005 and will be re-examined in Spring 2015.
| |
| Table 5 includes 5 Category welds without effective hydrogen water chemistry. A 25%
| |
| sample was used; therefore 2 welds were selected and will be examined on a 10-year interval frequency. Two were examined in Spring 2000 and will be re-examined in 2009.
| |
| Table 6 includes 18 Category C welds with effective hydrogen water chemistry. A 10%
| |
| sample was used; therefore 2 welds were selected and will be examined on a 10-year interval frequency. Two were examined in Spring 2000 and will be re-examined in 2009.
| |
| Table 7 includes 4 Category D welds without effective hydrogen water chemistry. These four welds are listed as Category D because there is a potential that they are not fully stress improved. The three RHR welds were examined in 2005 and are scheduled for examination every 2nd outage (2009 and 2013). The feedwater weld is a special case because it cannot be inspected per Appendix VIII since it adjoins a weld overlay. It is conservatively listed as Category D because of relaxation issues due to the application of the adjacent weld overlay; however, some compressive forces will be observed at the ID due to the overlay. An Appendix VIII, automated examination will be attempted in 2009.
| |
| Future recommendations will be made at that time.
| |
| Table 8 includes one Category E overlaid weld without effective hydrogen water chemistry.
| |
| It will be examined on a 10-year interval frequency. This overlay was examined in 2005 and will be re-examined in 2015.

| |
| | |
| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 CATEGORY A WELDS The materials in Category A are resistant to IGSCC due their metallurgical properties. As such, the current required inspection scope and frequency per NUREG-0313 and GL 88-01 is 25% of the population every 10 years.
| |
| New Category A Examination Frequency Per BWRVIP-075-A, the new examination frequency for Category A welds is a function of their ASME Section XI Code classification.
| |
| B-F Scope (N/A to Hatch 2)
| |
| Category A welds, that are currently classified as Section XI Category B-F welds, will be examined at a rate of 25% over ten years. For welds that are protected by effective HWC, the BWRVIP proposed that the sample size for Category B-F welds is 10%. Fifty percent (50%) of these examinations must be completed during the first six years of the ten-year interval. Hatch 2 does not have any welds with this designation.
| |
| B-J Scope The BWRVIP proposed that welds that are currently classified as Category A and are classified as Section XI Category B-J per Section XI be examined at a rate of 10% over ten years. Fifty percent (50%) of these examinations must be completed during the first six years of the ten-year interval.
| |
| New Category A Scope of Examinations As shown in Table 2, there are 67 HNP-2 Category A welds; therefore seven welds require examination during the 4th Interval. Four of these welds must be examined prior to the end of 2011.
| |
| Risk Insights Used During Selection of the Category A Welds Per Section 4.1 of BWRVIP-75-A the most risk significant piping is the reactor coolant pressure boundary that supports the ECCS function or containment outside the drywell and that are subject to thermal fatigue or crevice corrosion in addition to IGSCC. Piping that functions only as the RCPB would generally have lower risk.
| |
| As shown in Table 2, there are 30 Category A HNP-2 welds that form the pressure boundary for RHR Injection (which is an ECCS function). None of the welds have an outboard containment isolation function or have been identified as being susceptible to thermal fatigue. Therefore, the welds to be examined will be selected out of the 30 weld ECCS subset. Twenty-four welds are located in the Reactor Recirculation system on the Hatch 2 Basis Doc-VIP75.doc Page 5 of 40 Rev.1.0
| |
| | |
| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 12 risers, the 22 headers, and the 28 piping downstream of the 2B31-F031A&B valves.
| |
| Six welds are located in the RHR LPCI lines.
| |
| Category A Weld Selection Per Section 4.1 of BWRVIP-75-A, during the selection of locations for inspection, consideration should be given regarding locations where IGSCC could be accelerated by crevice corrosion or thermal fatigue. In addition, locations having attributes that would promote IGSCC should have higher priority for inspection. The attributes that may be considered include: high carbon or low ferrite content, crevice or stagnant flow conditions, evidence of weld repair, surface cold work, and high fit-up, residual and operating stresses.
| |
| For the 24 Reactor Recirculation system welds that have an ECCS function, all have received an effective stress improvement and all are subject to effective hydrogen water chemistry (HWC). For the 6 RHR welds all received an effective stress, but none are subject to effective HWC because they are located in stagnant lines.
| |
| In the report, Weld Prioritization for Adoption of BWRVIP-075 at Edwin I. Hatch Unit 1 and Unit 2, dated June 2001, Structural Integrity Associates (SIA) stated in Section 3.0, Weld Selection Process that, consideration should be given to those locations having attributes that would promote IGSCC, or where IGSCC could be accelerated by crevice corrosion or thermal fatigue. These attributes include: high carbon or low ferrite content, crevice or stagnant flow conditions, evidence of weld repair, surface cold work, and high fit-up, residual and operating stresses. Each weld was assigned a rank of 1 to 5, with a Priority 1 being considered to be the most susceptible to IGSCC. These attributes are very similar to those in BWRVIP-75-A; therefore, the SIA document was used for guidance in selecting welds. This prioritization is shown in column 4 (SIA Priority) of Table 2. The welds in Table 2 were designated by SIA as either Priority 2 or Priority 4.
| |
| Two Priority 4 welds in the RHR lines were selected even though they had a lower SIA priority because they are located in stagnant flow lines and are not subject to the additional mitigating effects of HWC. Five Priority 2 welds in the Recirculation system (with effective HWC) were also selected. Four welds (57%) were selected for the 1st Period and three welds (43%) were selected for the 3rd Period.
| |
| New Category A Scope Expansion The sample expansion criteria to be used for Category A are similar to those specified in GL 88-01. If one or more welds are determined to be cracked by this examination program, an additional sample of equal size and approximately the same distribution will be examined during the same outage. If cracking is detected in the second sample, 25% of the remaining population will be examined. If additional cracking is detected, the entire Category A population will be examined. The size or distribution of the expanded sample may be altered if technical justification exists. If this option is used, the NRC will be notified when the expanded scope examinations begin.

| | |
| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 CATEGORY C WELDS Category C welds are made from material that is considered susceptible to IGSCC, but mitigated by stress improvement after more than two cycles of operation. GL 88-01 specifies that the entire population is to be examined once every ten years.
| |
| New Category C Examination Frequency Category C welds that satisfy the following criteria may be examined at a rate of 25% per ten years. The licensee must ensure that an effective stress improvement was achieved.
| |
| Additionally, there must have been either:
| |
| a) a preservice (post-stress improvement) and inservice examination with a qualified procedure with no cracking identified, or b) For welds that were stress improved prior to the publication of BWRVIP-75-A but did not receive a preservice examination, at least one examination performed with a qualified procedure after more than two operating cycles and no cracking detected.
| |
| With effective hydrogen water chemistry (HWC), the scope may be further reduced to 10%
| |
| of the population.
| |
| For HNP-2, each Category C weld has had an effective stress improvement and received a post-stress improvement examination and with at least one examination using qualified procedures. See Appendix A for the basis for Qualified Examinations and Appendix C for the basis for Effective Stress Improvement.
| |
| New Category C Scope of Examinations Category C welds consist of similar metal (SM) welds and dissimilar metal (DM) welds, and are listed in the following tables:
| |
| Table 3 - DM Welds With Effective Stress Improvement Without Effective HWC Table 4 - DM Welds With Effective Stress Improvement With Effective HWC Table 5 - SM Welds With Effective Stress Improvement Without Effective HWC Table 6 - SM Welds With Effective Stress Improvement With Effective HWC Risk Insights Used During Selection of the Category C Welds Per Section 4.1 of BWRVIP-75-A the most risk significant piping is the reactor coolant pressure boundary that supports the ECCS function or containment outside the drywell and that are subject to thermal fatigue or crevice corrosion in addition to IGSCC. Piping that functions only as the RCPB would generally have lower risk. Applicable ECCS functions for this piping are HPCI, RHR Injection, and Core Spray. None of the welds have an outboard containment isolation function or have been identified as being susceptible to thermal fatigue.

These attributes are very similar to those in BWRVIP-75-A; therefore, the SIA document was used for guidance in selecting welds. All dissimilar metal welds are Priority 1; therefore, the following additional information was considered:
| |
| : 1. Issues with previous examinations based on a review of the previous data by Level III personnel. (See Column 2).
| |
| : 2. Issues with weld crowns or taper that would prevent an Appendix VIII examination from being performed. (See Column 3).
| |
| : 3. Evidence of Repair Work. (See Column 4).
| |
| The weld selection are discussed below.
| |
| Table 3 - There are 12 dissimilar metal welds that had an effective stress improvement mitigator as defined in Appendix C but do not have effective hydrogen water chemistry as defined in Appendix B. (The Feedwater welds may not have effective hydrogen water chemistry because there may be insufficient time for proper mixing from the injection point to these welds. The CRD weld and the Core Spray welds are in stagnant lines). Those welds highlighted in yellow are the one or more prerequisite examinations with a qualified procedure (as defined in Appendix A) prior to implementing the reduced scope.
| |
| The ECCS welds are the seven Feedwater welds which form a portion of the pressure boundary for HPCI and the two Core Spray welds. The sample size is 25% or three welds.
| |

Those welds highlighted in yellow are the prerequisite examinations with a qualified procedure (as defined in Appendix A) prior to implementing the reduced scope.

| The ECCS welds consist of the 10 safe-end to nozzle welds which form a portion of the pressure boundary for LPCI. Six of the welds 2B31-1RC-12AR-F-5, 2B31-1RC-12AR-H-5, 2B31-1RC-12AR-J-5, 2B31-1RC-12BR-B-5, 2B31-1RC-12BR-C-5, and 2B31-1RC-12BR-D-5 had records of repair by Combustion Engineering. The sample size is 10% or two welds. Two of the six welds were selected during the 3rd Period.
| |
| Table 5 - There are 5 similar metal welds that had an effective stress improvement mitigator as defined in Appendix C but do not have effective hydrogen water chemistry as defined in Appendix B. (The Feedwater welds may not have effective hydrogen water chemistry because there may be insufficient time for proper mixing from the injection point to these welds. The Jet Pump welds are in stagnant lines). Those welds highlighted in yellow are the prerequisite examinations with a qualified procedure (as defined in Appendix A) prior to implementing the reduced scope. The ECCS welds are the three Feedwater welds which form a portion of the pressure boundary for HPCI. The sample size is 25% or two welds. Two Feedwater welds were selected during the 1st Period.

| Table 6 - There are 18 similar metal welds that had an effective stress improvement mitigator as defined in Appendix C and have effective hydrogen water chemistry as defined in Appendix B. Those welds highlighted in yellow are the prerequisite examinations with a qualified procedure (as defined in Appendix A) prior to implementing the reduced scope. The ECCS welds consist of the ten 12 Recirculation system riser welds which form a portion of the pressure boundary for LPCI. Additionally, there are two RWCU welds (2G31-1RWCUM-6-D-15 and 16) that are located outside of containment. The sample size is 10% or two welds. Two 12 welds were selected during the 1st Period. Additionally, welds 2G31-1RWCUM-6-D-15, 16, and 17 are high-energy lines in a no-break zone that must be examined each ten years. Therefore, five welds will be examined during the 4th Interval.
| |
| Summary The number of welds to be examined for each table was calculated based on the 10% or 25% criteria. The number of welds to be examined within a table is the calculated value rounded up to the next whole number. Because each table is rounded up, conservatism is built into the sample size as shown below.
| |
| There are 17 Category C welds (see Tables 3 and 5) that do not have hydrogen water protection and that are in the 25% sample (5 welds). Within this group there are 10 Feedwater ECCS welds, 2 Core Spray ECCS welds, 4 RC non-ECCS welds, and 1 CRD non-ECCS weld. Selecting from the ECCS scope, as required by BWRVIP-75-A, welds 2B21-1FW-12AB-11, 2B21-1FW-12AB-12, 2B21-1FW-12AB-13, and 2B21-1FW-12BD-9 were selected for examination during the 1st Period of the 4th Interval.

| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 10A-21 and 2E21-1CS-10B-20 were selected for the 3rd Period. Additionally, weld 2B21-1FW-12AA-8 will be re-examined in 2R20. Therefore, 7 welds or 41% of the scope of welds without hydrogen water protection will be examined during the 4th Interval.
| |
| There are 30 Category C welds (see Tables 4 and 6) that have effective hydrogen water protection and that are in the 10% sample (3 welds). Within this group there are 20 RC ECCS welds, 2 RC non-ECCS welds, 2 Outboard Isolation RWCU welds, and 4 RWCU welds inside containment. Selecting from the ECCS and Outboard Isolation welds, as required by BWRVIP-75-A, welds 2B31-1RCM-12AK-3, 2G31-1RWCU-6-D-15, and 2G31-1RWCUM-6-D-16 were selected for examination during the 1st Period. Note:
| |
| 2G31-1RWCUM-6-D-17 will also be examined as an augmented high-energy line.
| |
| Welds 2B31-1RC-12AR-H-5 and 2B31-1RC-12AR-J-5 will be examined during the 3rd Period. Therefore, 6 welds or 20% of the population with hydrogen water protection will be examined during the 4th Interval.

| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 CATEGORY D WELDS Category D welds are those made of susceptible material that have not been treated with an IGSCC remedy and in which cracks have not been reported.
| |
| New Category D Examination Frequency Category D welds are required to be examined at a frequency of 100% of the population every six years. For plants on two year fuel cycles, this is 100% every three outages.
| |
| For welds that are effectively protected with HWC, the inspection interval can be increased so that the entire Category D population will be examined every 10 years, with at least 50% inspected during the first six years. See Table 7.
| |
| Category D Scope Weld 2E11-1RHRM-24A-10 Per drawing S-28482, ISI weld number 2E11-1RHRM-24A-10 was originally field weld 2FW-6419.
| |
| 2FW-6419 joined 304 stainless steel (Pullman-Kellogg Spool 2E11-RHR-184) to carbon steel piping (Pullman-Kellogg Spool 2E11-RHR-184A). Spool drawing 2E11-RHR-184A indicates that the carbon steel piping was buttered in the shop per SK#92, machined, and then stress relieved. The butter material (not identified), most likely, would have been Inconel 82 using machine welding or Inconel 182 using stick welding. Per S-28483, 2FW-6419 had a GTAW root (Inconel 82) and was SMAW (stick welded Inconel 182) welded out. Note: NUREG-0313 considers Inconel 82 to be resistant to stress corrosion cracking (not Inconel 182).
| |
| During the 1984 pipe replacement (see DCR 83-173) to change out the 304 SS piping to 316 NG SS, a cut was made at 2FW-6419. The Inconel butter remained and possibly a portion of the original weld remained as a safe-end. This safe-end was then machined and welded to the 316NG SS (without having to perform additional stress relieving of the carbon steel pipe, since the carbon steel piping was not welded on). Actual details of the cut requires the weld traveler sheet which has not been located. The replacement spool for 2E11-RHR-184 is shown on drawing S-60048. Per the Newport News Weld History Record archived on Spool 004737, Sheet 256, the weld material is
| |
| .035 diameter Bare Wire ERNiCr-3 (Inconel 82). This weld history record also indicates that there was a root repair requiring the excavation of an area and subsequent re-welding. After welding, this weld underwent Induction Heat Stress Improvement (IHSI); however the IHSI process used a short active heating coil to prevent heating of the carbon steel piping and the determination that an effective stress improvement process has not been made.
| |
| This weld is not effectively protected by HWC because it is located in a stagnant line, it contains unidentified Inconel butter material, and it may not have had a successful IHSI process. Therefore, it was conservatively classified as Category D. The first examination using the Performance Demonstration Initiative (PDI) requirements was performed in February 2005 with a total coverage of 67% (no scans for axial flaws were possible) This weld consists of a thick elbow with the weld Hatch 2 Basis Doc-VIP75.doc Page 11 of 40 Rev.1.0
| |
| | |
| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 tapering down to the thinner carbon steel piping. Additionally, there is dip on the carbon steel side near the edge of the weld butter. This configuration does not meet PDI requirements for examination of dissimilar metal welds. However, if stress corrosion cracking occurs in this weld it should originate at the ID of the butter material, because the rest of the material in the weld joint (carbon steel, 316NG SS, and Inconel 82) have minimal susceptibility to stress corrosion cracking.
| |
| From the 2005 coverage plots, there was no coverage for scans looking for axial flaws. For scans for circumferential cracking the following coverage was obtained:
| |
| 45-degree shear wave - 100% of the base metal 45-degree RL - 78% of the required volume 60-degree RL - 91% of the required volume Most importantly, the area of interest was scanned with the 45-degree RL transducer from the stainless elbow side and scanned from both sides with the 60-degree RL transducer. Therefore, while not meeting PDI requirements, an adequate technical examination was achieved and reasonable assurance of structural integrity was maintained. As a Category D weld, it will need to be re-examined in 2011, but was scheduled for 2009 to coincide with the SMART exams.
| |
| Note:
| |
| If it is determined that this weld had an effective IHSI it may be re-categorized as Category C.
| |
| Additionally, if documentation is found that shows that the weld butter is Inconel 82, then the weld may be re-categorized as Category A.

| Weld 2B21-1FW-12AA-8 This Inconel weld joins a carbon steel pipe to a Inconel extension piece. On the Inconel side of the weld, there is a weld overlay which extends up to the edge of the weld. During the 3rd Interval examination was from both sides as shown in Figure 1. However, during the 4th Interval, the examination through the overlay has not been qualified per the Performance Demonstration Initiative and the taper on the carbon steel side will limit coverage. This weld had a mechanical stress improvement process (MSIP) performed on it in 1994. However, in the Flaw Tolerance Evaluation for this weld performed by Structural Integrity Associates (SIA) as documented in their August 25, 2006 letter SIR-06-357, Rev. 0, SIA concluded that during the weld overlay repair, because weld #8 is in close proximity to the weld overlay, the weld #8 induced residual stress may be relieved, if not completely relieved, due to the large number of elastic-plastic thermal stress cycling from the weld overlay repair process at weld #9. The as-welded stresses at weld #8 could be replaced by the stress induced by the weld overlay. Therefore, it is considered conservative in the present flaw tolerance evaluation to use the weld #8 as-welded residual stresses with an inside surface residual stress magnitude equal to the yield strength of the material. Additionally, the effects of hydrogen are probably limited in feedwater, therefore this weld has been designated as Category D.

| : 1. To have effective hydrogen water chemistry at Hatch requires a combination of noble metal addition and a reduced hydrogen injection rate. The Feedwater nozzle safe-ends (2B21) are not believed to have totally effective hydrogen water chemistry because the hydrogen is injected into the Feedwater lines and sufficient mixing may not have occurred. The Core Spray (2E21) safe-ends, the Jet Pump Instrument nozzle (2B31) safe-ends, and the CRD Return nozzle (2C11) safe-end are not protected by hydrogen water chemistry because of stagnant conditions due to the geometrical configuration.

A review of the previous data indicated the need for a re-examination in 2005. The re-examination was performed in 2005. A review of the data did not indicate any basis for re-examination.
| |
| : 6. Three manual examinations were performed (1994 baseline, 1997, and 2000) on welds 2B31-1RC-4JP-A-1 and 2B31-1RC-4JP-B-1 using a qualified procedure and personnel qualified for IGSCC detection. A review of the data did not indicate any basis for re-examination.
| |
| : 7. Three examinations were performed (1994 baseline, 1997, and 2000) on weld 2C11-1CRD-3-R-1 using a qualified procedure and personnel qualified for IGSCC detection. An Appendix VIII examination was performed in 2005 with 100% coverage. It should be noted that this weld was stress improved in 1994, but effective hydrogen water chemistry is not achieved because of the stagnant configuration.

| |
| : 1. Each weld was stress improved with MSIP in 1994. MSIP is considered to be an effective stress improvement process. Effective hydrogen water chemistry at Hatch is implemented using noble metal addition and a reduced hydrogen injection rate. The Feedwater nozzle safe-ends (2B21) are not believed to have totally effective hydrogen water chemistry because the hydrogen is injected into the Feedwater lines and sufficient mixing may not have occurred.
| |
| The Jet Pump Instrument nozzle (2B31) safe-ends are not protected by hydrogen water chemistry because of stagnant conditions due to the geometrical configuration. With a stagnant condition it is unlikely that the welds were coated with noble metal.
| |
| : 2. Two examinations were performed using NDE personnel qualified for IGSCC detection.
| |
| These examinations were a 1994 automated baseline using GE procedure UT-HAT-208V0/0 and a 1997 automated inservice examination using GE procedure UT-HAT-208V0/1. As discussed in the Qualified Examination section of this report UT-HAT-208V0/0 and UT-HAT-208V0/1 both utilized the same essential variables as were later used for PDI demonstrations (on dissimilar metal welds). Therefore, these examinations met the BWRVIP-075 requirement for qualified examinations. In addition, welds 2B21-1FW-12BC-12 and 2B21-1FW-12BD-9 were re-examined in 2000 using a qualified procedure and personnel qualified for IGSCC detection. These 2000 examinations were performed after the March 1, 1996 (transition letter) and about the time Appendix VIII stainless was implemented for stainless steel piping (5/22/2000). Welds 2B21-1FW-12BC-12 and 2B21-1FW-12BD-9 have an ECCS function (HPCI injection path) and their re-examination satisfies the 25% sample rate during the 3rd 10-year interval. They will be re-examined in 2015.
| |
| : 3. Two examinations were performed using SNC manual examination procedures and NDE personnel qualified for IGSCC detection. These examinations were a 1994 manual baseline using procedure UT-H-400/12 (pre-1996 transition letter) and a 1997 inservice examination using procedure UT-H-400/16 (post-1996 transition letter). While UT-H-400/12 was developed and used prior to the 1996 transition letter, it used similar techniques to those used later in UT-H-400/16, and therefore it is also considered to meet the intent of the BWRVIP-075 requirements for a qualified examination.

| |
| : 1. Each weld had an effective IHSI stress improved in 1986 and effective hydrogen water chemistry is implemented.
| |
| : 2. Two examinations were performed using NDE personnel qualified for IGSCC detection. These examinations were a 1988 inservice examination using SNC manual procedure UT-H-401/6 (pre-1996 transition letter) and a 2000 automated inservice examination using GE procedure GE-UT-230/2 (post-1996 transition letter). While UT-H-401/6 was developed and used prior to the 1996 transition letter, it used similar techniques to those used in post-1996 implementation letter IGSCC detection procedures ,
| |
| and therefore it is also considered to meet the intent of the BWRVIP-075 requirements for a qualified examination. The 2000 automated examinations were performed after the March 1, 1996 transition letter and about the time Appendix VIII was implemented for stainless steel piping (5/22/2000) and also meet the BWRVIP-075 requirements for a qualified examination.
| |
| : 3. Two examinations were performed using NDE personnel qualified for IGSCC detection. These examinations were a 1988 inservice examination using SNC manual procedure UT-H-401/6 (pre-1996 transition letter) and a 1997 automated inservice examination using GE procedure UT-HAT-208V0/1(post-1996 transition letter). While UT-H-401/6 was developed and used prior to the 1996 transition letter, it used similar techniques to those used in post-1996 implementation letter IGSCC detection procedures , and therefore it is also considered to meet the intent of the BWRVIP-075 requirements for a qualified examination. The 1997 post-1996 transition letter examinations using UT-HAT-208V0/1 utilized the same essential variables as were later used for PDI demonstrations (on dissimilar metal welds). Therefore, these examinations met the BWRVIP-075 requirement for two qualified examinations.
| |
| Additionally, welds 2B31-1RCM-12AK-3 and 2B31-1RCM-12BD-2 (which have an ECCS function) were re-examined in 2000 using GE automated procedure GE-UT-230/2. These 2000 automated examinations were performed after the March 1, 1996 transition letter and about the time Appendix VIII was implemented for stainless steel piping (5/22/2000). These two examinations satisfied the 10%
| |
| examination requirement.
| |
| : 4. These six Category C welds join replacement piping made from resistant material (316NG) to original RWCU valves (or the containment penetration in one case). Two examinations were performed on each weld using NDE personnel qualified for IGSCC detection. In 1988 an inservice examination using SNC manual procedure UT-H-401/6 (pre-1996 transition letter) was performed on all six welds. While UT-H-401/6 was developed and used prior to the 1996 transition letter, it used similar techniques to those used in post-1996 implementation letter IGSCC detection procedures , and therefore it is also considered to meet the intent of the BWRVIP-075 requirements for a qualified examination.
| |
| : 5. 2G31-1RWCUM-6-D-6&7 were re-examined in 1997 using SNC manual procedure UT-H-400/16.
| |
| These examinations were performed after the March 1, 1996 transition letter and are considered as qualified examinations. In 2000, an inservice examination was performed on the remaining four welds using SNC manual procedure UT-H-402/1. These 2000 automated examinations were performed after the March 1, 1996 transition letter and about the time Appendix VIII was implemented for stainless steel piping (5/22/2000).

| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 APPENDIX A DETERMINATION OF QUALIFIED EXAMINATIONS Per BWRVIP-075, the training and qualification of examiners and procedures for application to BWR stainless steel piping welds was established in the mid 1980s and governed under the IGSCC/NDE Coordination Plan, also referred to as the Three Party Agreement. The IGSCC/NDE Coordination Plan was jointly developed and approved by the NRC, EPRI, and the BWR Owners Group on IGSCC Research and was documented in GL88-01 and NUREG-0313, Rev 2. GL 88-01 states in part: the detailed procedure, equipment and examination personnel shall be qualified by a formal program approved by the NRC such as that being conducted in accordance with the NDE Coordination Plan agreed upon by NRC, EPRI and the BWROG. The most significant improvements in inspection methods were well implemented by 1988, and the examinations performed since that time (and in accordance with GL 88-01) are considered very reliable. Per BWRVIP-075, personnel and procedures used for the examination of piping must have been and will continue to be in accordance with one of the following two documents.
| |
| o The program identified in William T. Russell, Transition From the IGSCC Qualification Program to the Performance Demonstration Initiative Program, letter to K. P. Donovan, March 1, 1996.
| |
| o Performance Demonstration Initiative (PDI), Performance Description, Revision 1, Change 1, December 1996 (or later).
| |
| For HNP-2, the timing of the implementation of these improved inspection methods is contingent on the type of weld. Dependent upon the type of weld (dissimilar or similar), the improvements in inspection methods may have been adopted prior to the William T. Russell 1996 letter. These weld types are addressed below.
| |
| Dissimilar Metal Welds - These welds have historically been difficult to examine for IGSCC detection due to their configuration. Because of this difficulty, GE issued SIL-455 which incorporated L-wave techniques and other improvements for the detection of IGSCC. Since the issuance of SIL-455, other issues have been identified concerning the weld crown configuration. It is the position of M&IS Level III personnel, that when NDE personnel qualified for IGSCC detection used NDE procedures incorporating SIL-455, that the examinations were qualified provided that the existing weld crown contours would now be acceptable for Appendix VIII examinations. In general, those examinations performed on welds that would not meet Appendix VIII requirements for weld crowns would not be considered as qualified examinations. Acceptable procedures are:
| |
| : a. GE procedure UT-HAT-208 Version 0, Revision 0 and up, Procedure for Automated Ultrasonic Examination of Similar and Dissimilar Metal Piping Welds used the same essential variables that were used for Appendix VIII qualification.
| |
| Hatch 2 Basis Doc-VIP75.doc Page 32 of 40 Rev.1.0
| |
| | |
| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 This procedure was used in 1994 and 1997 and meets the BWRVIP-075 intent for a qualified procedure.
| |
| : b. GE procedure UT-HAT-209 Version 0, Procedure for Automated Ultrasonic Examination of Dissimilar Metal Piping Welds used the improved refracted L wave inspection techniques per GE SIL 455 and examination personnel were qualified for IGSCC detection. This procedure was used in 1994 and 1997 and meets the BWRVIP-075 intent for a qualified procedure.
| |
| : c. GE procedure GE-UT-209 Revision 6, Procedure for Automated Ultrasonic Examination of Dissimilar Metal Piping Welds used the same essential variables that were used for Appendix VIII qualification. This procedure was used in 2000 and meets the BWRVIP-075 intent for a qualified procedure.
| |
| : d. SNC Procedure UT-H-409, Revisions 5 and up used the improved refracted L wave inspection techniques per GE SIL 455, Revision 1 and examination personnel were qualified for IGSCC detection. Versions of this procedure were used in 1989, 1994, 1997, and 2000 and meets the BWRVIP-075 intent for a qualified procedure.
| |
| : e. SNC Procedure UT-H-810/0 used the P-SCAN and used the improved refracted L wave inspection techniques per GE SIL 455, Revision 1 and examination personnel were qualified for IGSCC detection. This procedure was used in 1991 and meets the BWRVIP-075 intent for a qualified procedure.
| |
| Similar Metal Welds - For similar metal welds, it is the position for HNP-2 that the NDE techniques (personnel and procedures) used from 1988 until the present are considered acceptable for the detection of IGSCC. Therefore, those welds receiving an examination by IGSCC qualified personnel using one of the below listed procedures has received a qualified examination.
| |
| : a. GE procedure UT-HAT-208 Version 0, Revision 0 and up, Procedure for Automated Ultrasonic Examination of Similar and Dissimilar Metal Piping Welds used the same essential variables that were used for Appendix VIII qualification.
| |
| This procedure was used in 1994 and 1997 and meets the BWRVIP-075 intent for a qualified procedure.
| |
| : b. GE procedure GE-UT-230/2. This procedure was used in 2000 after the issuance of the Transition From the IGSCC Qualification Program to the Performance Demonstration Initiative Program, 1996 letter and thus meets the BWRVIP-075 intent for a qualified procedure.
| |
| : c. SNC procedure UT-H-402/1. This procedure was used in 2000 after the issuance of the Transition From the IGSCC Qualification Program to the Performance Demonstration Initiative Program, 1996 letter and thus meets the BWRVIP-075 intent for a qualified procedure.

| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2
| |
| : d. SNC procedure UT-H-400/16. This procedure was used in 1997 after the issuance of the Transition From the IGSCC Qualification Program to the Performance Demonstration Initiative Program, 1996 letter and thus meets the BWRVIP-075 intent for a qualified procedure.
| |
| : e. SNC procedure UT-H-400/12. This procedure was used in 1994 before the issuance of the Transition From the IGSCC Qualification Program to the Performance Demonstration Initiative Program, 1996 letter. However, the techniques are similar to that for Revision 16; therefore, it meets the BWRVIP-075 intent for a qualified procedure.
| |
| : f. SNC procedure UT-H-401/8. This procedure was used in 1988 before the issuance of the Transition From the IGSCC Qualification Program to the Performance Demonstration Initiative Program, 1996 letter. However, the techniques are similar to that for current revisions; therefore, it meets the BWRVIP-075 intent for a qualified procedure.

| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 APPENDIX B DETERMINATION OF EFFECTIVE HYDROGEN WATER (HWC)
| |
| Per BWRVIP-075, plants that operate with effective HWC may further reduce their inspection frequency. The definition of effective HWC is provided in Section 3.6 of BWRVIP-075. BWRVIP states that licensees that take credit for HWC should verify and validate that an effective HWC program, in accordance with the staff-approved BWRVIP-62 guidelines, has been achieved. BWRVIP-62, titled Technical Basis for Inspection Relief for BWR Internal Components with Hydrogen Injection, provides the technical bases and criteria for an effective HWC/NMCA program to mitigate IGSCC of BWR internals and to demonstrate that inspection relief is justified for BWR internals. HNP-2 will follow the guidance in BWRVIP-62 for an effective HWC program in regards to piping and vessel internals inspection relief.2 HNP-2 has overall effective hydrogen water chemistry (HWC) as determined by the measured ECP value at the bottom of the RPV. To achieve effective HWC, HNP-2 periodically injects noble metal and continuously injects a reduced level of hydrogen.
| |
| Issue By EPRI letter dated April 27, 2006 from Robin Dyle and Tom Mulford, the BWRVIP issued instructions to the industry that generic application of inspection relief for HWC or NMCA should not be used until the NRC SE on BWRVIP-62 is issued. The letter also indicated that the application of BWRVIP-62 to BWRVIP-75-A inspections is not generically authorized, but plant-specific application can be pursued with the NRC as noted on Footnote 1 of Table 3-1 or in Section 3.6 of BWRVIP-75-A.
| |
| | |
| ===Response===
| |
| HNP is using specific relief.
| |
| Evaluation By letter dated June 23, 2000, SNC submitted a request to adopt the guidance contained in the October 1999 version of BWRVIP-75 for weld examination sample determination and scope expansion criteria, beginning with the Unit 1 Fall 2000 outage. By letter dated October 10, 2000 the NRC issued a letter enclosing the HNP Safety Evaluation (SE).
| |
| Within the HNP SE the NRC indicated that the NRC staff had reviewed the BWRVIP-75 report (and issued its generic Safety Evaluation (SE) in a letter dated September 15, 2000) and found VIP-75 acceptable except for certain open items. One of these open items dealt with defining effective hydrogen water chemistry (HWC). Section 3.6 of BWRVIP-75 stated, for the purposes of this report, effective HWC (including NMCA) is any combination of electrochemical corrosion potential(ECP) and percent availability that results in a factor of improvement of 3, or higher on crack growth as defined using the means described in BWRVIP-62. To address the NRC questions SNC provided justification in the form of an attachment to the June 23, 2000 letter. It stated:

| |
| | |
| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 The Chemistry Monitoring Program at Plant Hatch provides guidance for operating both Units in accordance with the EPRI BWR Water Chemistry guidelines. Water chemistry control parameters are monitored and action levels are used by plant staff members to correct water chemistry conditions and evaluated those conditions, as required.
| |
| Hatch Unit 2 has been operating with HWC since September of 1991. From May 1994 to March 2000 (Cycles 12, 13, 14, &15), Unit 2 has operated under moderate HWC with hydrogen injection at 35 - 55 SCFM, conductivity measured in the 0.08 to 0.14 S/cm range, and Electro-Chemical Potential (ECP) measurements in the -400 to -450 SHE range. HWC availability has been maintained at > 80% since the initial implementation. At the shutdown of Cycle 15 (Spring 2000), NobleChem (NMCA) was added to Unit 2. The NobleChem addition was implemented with both reactor coolant system (RCS) recirculation pumps in operation to achieve as much distribution to the RCS piping as possible. During Cycle 16 (current cycle), hydrogen injection has been maintained at 6 to 8 SCFM and ECP is measured at -450 to -480 SHE.
| |
| Within the HNP SE, the NRC concluded that SNCs response to the open item in the BWRVIP-75 SE was acceptable. Therefore specific relief regarding the HWC/NMCA program at Hatch was granted.
| |
| Footnote 1 of Table 3-1 of BWRVIP-75-A states, For the examination sample percentages that are less than required by ASME Section XI, a licensee will need to pursue an alternative to 10 CFR 50.55a requirements for category B-J and B-F welds pursuant to 10 CFR 50.55a(a)(3)(i).
| |
| Pursuant to 10 CFR 50.55a(a)(3)(i), SNC submitted alternative RR-39 for the 3rd Interval and approval was granted by the NRC on January 7, 2005. For the 4th Interval SNC submitted ISI-ALT-3 which was approved by the NRC on December 22, 2005.
| |
| Current Implementation of HWC and NMCA ISI-ALT-3 was submitted to continue use of the guidance contained in the Electric Power Research Institute (EPRI) proprietary report TR-113932, "BWR Vessel and lnternals Project, Technical Basis for Revisions to Generic Letter 88-01 Inspection Schedules (BWRVIP-75)," dated October 1999, as revised by the Nuclear Regulatory Commission (NRC) staff's final Safety Evaluation dated May 14, 2002, in lieu of the licensee's commitments to Generic Letter 88-01 and NUREG-0313, Revision 2. The NRC staff concluded that the licensee's proposed alternative provides an acceptable level of quality and safety. The NRC staff authorized the proposed alternative for the fourth 10-year inservice inspection interval. Dennis Rickertson was requested to compare the HWC/NMCA program at Hatch versus the NRC Open Item 3.8 in the NRCs SE and subsequently supplied the following information.

| Supplementary Information on Implementation of BWRVIP-62 December 17, 2004 Hatch IGSCC Mitigation History and Strategy Hydrogen Water Chemistry was initiated to mitigate IGSCC of Recirculation System piping (Unit 1 Sept 1987, Unit 2 Sept 1991). From 1992 to 1995, hydrogen injection flow rates were gradually increased from 22 SCFM to 50 SCFM to mitigate IGSCC of reactor vessel internal lower plenum area. From 1995 to 1999, Hatch operated with moderate hydrogen injection rates of 45 to 55 SCFM. NMCA was applied to Unit 1 at the End of Cycle (EOC) 18 in March of 1999 and Unit 2 at the EOC 15 in March of 2000. For the operating cycle after NMCA, the target hydrogen injection flow rates were set at 10 SCFM (0.26 ppm) in the feedwater. From 1998 to 2002, SNC participated in the Japanese Owners Group (JOG) program which evaluated HNP-2 reactor vessel lower head region for protection via extensive ECP monitoring.
| |
| Current HNP IGSCC Mitigation Strategy is to continue to use NMCA with hydrogen injection at 10 SCFM. The primary methods of monitoring hydrogen water chemistry effectiveness of mitigating IGSCC are ECP monitoring and Noble Metal durability monitoring. Also the feedwater hydrogen injection flow rate is monitored and the Molar Ratio of Hydrogen to Oxidants is calculated using the BWRVIA computer model. These two methods are secondary methods of monitoring HWC effectiveness. At a hydrogen injection flowrate of 10 SCFM, ECP values are normally -450 to -490 mV (SHE) at the Bottom Head Drain Line, Recirculating System piping, and MMS.
| |
| Also with the feedwater hydrogen injection flow rate of 10 SFFM, the results of the BWRVIA model indicate Molar Ratios greater than 3 in the recirculation piping and reactor internals (except the mixing plenum) locations. A Molar Ratio greater than 3 indicates ECP values are in the - 400 mV range. The BWRVIA model indicates that at a Feedwater hydrogen injection rate of 10 SCFM the Molar Ratio in the Recirculating System piping is greater than 10. The NRC SE for BWRVIP-62 (letter of Jan 30, 2001) indicates: for an acceptable NMCA program the Molar Ratio should be 4 and above, and that HWC % availability should be > 90%. Supplementary information was provided to the NRC (BWRVIP letter of December 17, 2004) indicating that a molar ratio of > 3 is sufficient to mitigate IGSCC (ECP < -230 mV).
| |
| Results of the Hatch HWC Percent Availability calculations indicate that for Unit 1 since November 1997, the percent availability has been greater than 80 %. For Unit 2, since April 1997, the percent availability has been greater than 80 %. Both Units have HWC percent availability > 90 % after the NMCA applications: Unit 1 1999 EOC18, and Unit 2 2000 EOC15.

| Water Chemistry and durability monitoring results will be reviewed periodically with GE to determine when NMCA should be re-applied.
| |
| Locations Where Effective HWC/NMCA is Not Credited It should be noted that while HNP-1 has effective HWC, individual welds may or may not have effective HWC because of their location. To have effective HWC at each weld of interest, the noble metal must have plated out on each weld to provide protection for the weld, and the water chemistry at each weld must have sufficient hydrogen to sufficiently lower the oxygen content. For HNP-1, all welds are considered to have effective HWC except for the following.
| |
| o Welds located in stagnant areas, including:
| |
| Core Spray nozzles - carbon steel pipe to stainless safe-end extension (1 dissimilar metal weld per nozzle), stainless steel safe-end extension to stainless steel safe-end (1 similar metal weld per nozzle), and stainless steel safe-end to Inconel buttered nozzle (1 dissimilar metal weld per nozzle).
| |
| Jet Pump Instrument safe-end welds (2 nozzles with 2 welds on each nozzle).
| |
| CRD nozzle to cap weld (1 nozzle with 1 weld).
| |
| o Welds located in piping with no flow during power operation including:
| |
| * RHR Suction Line - Welds downstream of the RWCU connection.
| |
| * RHR Injection Lines - All welds.
| |
| The Recirculation Inlet nozzle to safe-end welds were also evaluated because they are covered by a thermal sleeve. Per drawing 2-BF-2, the thermal sleeve is open-ended on the downstream side. Therefore, flow turbulence inside the RPV can cause flow under the thermal sleeve and these welds are considered as protected by hydrogen water chemistry.

| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 APPENDIX C DETERMINATION OF EFFECTIVE STRESS IMPROVEMENT Processes used at HNP-2 were Induction Heating Stress Improvement (IHSI) and the Mechanical Stress Improvement Process (MSIP). Internal meetings were held on August 2-3, 2003 to assess compliance with the Draft A-Version of BWRVIP-075 that, The Owner must ensure that an effective stress improvement was achieved. It was agreed that those welds receiving an MSIP treatment had an effective stress improvement; however, it was concluded that SNC had not performed sufficient actions to ensure that an effective stress improvement was achieved for those welds receiving the IHSI process. To provide this assurance, it was recommended that the NUTECH process for IHSI at Hatch be evaluated against later BWRVIP-61 recommendations for an effective stress improvement using the following criteria:
| |
| o If the NUTECH procedures met the BWRVIP-61 guidelines, then an effective IHSI was considered to have been performed.
| |
| o For those welds where the NUTECH procedure did not meet BWRVIP-61 guidance, if the NUTECH data complied with the BWRVIP-61 parameters, then an effective stress improvement was considered to have been performed.
| |
| o For those welds whose data did not meet the BWRVIP-61 parameters, an evaluation was to be performed to determine the effectiveness of the stress improvement.
| |
| As a result, the IHSI process for each weld was independently evaluated by Martin B.

| |
| & 2 IHSI Effectiveness Review is being issued by Metallurgy & Material Applications to document the results. An E-Mail from M. B. Sims to M. Belford dated April 23, 2004 gave preliminary results which are shown below in italics. This E-Mail indicates that there is an issue with proving that the three dissimilar metal RHR welds had an effective IHSI process. Until other evidence is provided, these three RHR welds (2E11-1RHRM-20RS-3, 2E11-1RHRM-24A-10, and 2E11-1RHRM-24B-10) are considered as not having a effective IHSI process and are conservatively designated as Category D.
| |
| Some minor deviations from the recommended IHSI process parameters were noted, however, these deviations were either supported by mockup testing or not detrimental to IHSI effectiveness. As an example, the induction frequency was less than recommended 3-4 kHz range of BWRVIP-61 for all but one weld, but within the NUTECH procedure limit of 3-4 kHz +/-10%. Based on discussion with Tony Giannuzzi at Structural Integrity Associates (author of BWRVIP-61), a small reduction in induction frequency would produce deeper heating in the weld and not reduce IHSI effectiveness.
| |
| Therefore, these minor deviations in induction frequency do not affect IHSI effectiveness.

| FOURTH INTERVAL VIP-75 AUGMENTED PLAN HATCH UNIT NO. 2 Several nozzle-to-safe-end welds had outside surface temperatures outside the recommended range of 450-550 ºC in BWRVIP-61. These were within the limits of the originally recommended parameters of EPRI NP-2527-LD and NP-3375 (42575 ºC). A conservative upper limit was established in the original EPRI recommendations to prevent sensitization of the pipe surface, even though the IHSI heating time was not long enough for this to occur and the outside surface of the pipe is not exposed to conditions conducive to IGSCC. Exceeding this limit has no effect on effectiveness of stress improvement and should be considered acceptable. The lower limit was established to ensure sufficient through-wall T with cooling water flows greater than the minimum recommended. Based on the IHSI Weld Package data, the minimum recommended 275 ºC through-wall T was determined to be met at surface temperatures of 438 ºC or greater. Therefore, these nozzle-to-safe end welds are considered to have an effective stress improvement.
| |
| There are seven remaining welds in RHR that had recorded surface temperatures outside the recommended range of 450-550 ºC in BWRVIP-61. These were in Type 316NG material and were supported by a separate IHSI qualification for 316NG materials. NUTECH evaluated the effectiveness of IHSI on type 316NG in a 1984 report prepared for Georgia Power Company (report XGP-08-111) and established IHSI parameters with expanded surface temperature ranges and a higher minimum T of 550 ºF (288 ºC) to achieve effective stress improvement in 316NG material. All other IHSI parameters were the same as previous EPRI recommendations. IHSI of type 316NG does not appear to be addressed by BWRVIP-61, however based on the NUTECH qualification of the revised parameters and compliance with the remaining recommended parameters of BWRVIP-61, these welds are considered to have an effective stress improvement.
| |
| An open issue remains on whether the induction coil length was effectively reduced by "shorting" the coils on the three dissimilar metal welds. There is no mention of this in the IHSI Weld Packages for the site implementation, however, Tony Giannuzzi recalled it was addressed in the IHSI calculation packages that SIA had reviewed for other sites.
| |
| I have not been able to locate any IHSI calculation packages for Hatch to review this concern. I will check with the SNC Design Modifications Group to determine if these calculations were filed with the DCR files. Additional effort could be required to try to locate the original calculations at former NUTECH offices or by hand searches of plant records. This would be time consuming and expensive, so you would need to determine if the effort is warranted to reduce inspection frequency for the four welds that are impacted. (Note: These welds are currently listed as Category D welds, without credit being taken for IHSI).

| FOURTH INTERVAL AUGMENTED OTHER PLAN HATCH UNIT NO. 2 The NRCs safety evaluation dated 6/16/97 of the 3rd Interval ISI Program indicated, that in addition to the 1989 Code required examinations, certain augmented examinations would be performed per GPC commitment. The commitments along with the current implementation methodology are listed below and will also be followed for the 4th Interval.
| |
| High Energy Lines Outside Containment Augmented examinations on the Unit 2 main steam, feedwater, HPCI (steam), RCIC (steam) and RWCU high energy piping outside containment (where pipe breaks were not postulated) in compliance with Branch Technical Position MEB 3-1. Per Section 3.6.2.2.3 of the HNP-2 UFSAR, pipe breaks were not postulated in portions of high-energy piping extending from the containment penetration to the first inside and/or outside isolation valve for specified conditions. Therefore, for the above mentioned systems, volumetric exams are required on the welds between the inboard and outboard isolation valves to the extent practical. See Class 1 for a detailed evaluation.
| |
| Because these lines are also Class 1 lines for Section XI purposes, the high-energy Category B-J and XB-J welds are an integral part of the Class 1 Schedule Works tables.
| |
| Examination of IGSCC Susceptible Welds These examinations were originally performed per NUREG-0313 as modified by Generic Letter 88-01 and are currently performed per BWRVIP-075. A detailed evaluation is presented the BWRVIP-075 Section of this plan.
| |
| These welds are designated as Category OL-1, XB-J, and XB-F in the Schedule Works tables located in the BWRVIP-075 Section of this plan.
| |
| Core Shroud Examination Examination of the core shroud in accordance with Generic Letter 94-03. These examinations were originally performed as required. They are currently performed per BWRVIP requirements.
| |
| Scram Discharge Volume Piping A detailed evaluation is presented the Class 2 Augmented portion of this plan. Schedule Works tables are listed in this section under Category C-0803.
| |
| These welds are designated as Category C-0803 in the Schedule Works tables located in this portion of the plan.

| FOURTH INTERVAL AUGMENTED OTHER PLAN HATCH UNIT NO. 2 Feedwater Nozzles Augmented examination of the feedwater nozzles as specified by NUREG-0619 as modified by Generic Letter 81-11. These examinations were originally performed as required. They are currently performed per Alternate BWR Feedwater Nozzle Inspection Requirements, GE-NE-523-A71-0594-A, Revision 1, May 2000.
| |
| From 1974 to 1980, the inspection of feedwater nozzles by the industry indicated that there was some degree of cracking in the bore and inner radii of reactor vessel of reactor vessel feedwater nozzles in 18 of 23 commercially operating domestic BWRs. It was determined that most of the cracking was caused by lower temperature feedwater and CRD return line water leaking past interference fit spargers and initiating high-cycle thermal fatigue cracking in the clad nozzle inner radius and bore region. Startup and shutdown cycles would then drive the crack deeper into the nozzle. As a result, on November 13, 1980 the NRC issued NUREG-0619 detailing specific requirements to alleviate the cracking. Additional guidance was given in Generic Letter 88-11. The NRC staffs position was that the nozzles should be de-clad, the interference fit spargers replaced with an improved design, and the RWCU/CRD return lines re-routed such that the cooler water went through all the feedwater nozzles. The low-flow controllers should either be changed or a plant-specific fracture mechanics analysis should be performed that demonstrated that a crack would not grow to greater than one inch during the 40 year life of the plant. The history for HNP-2 is shown below in the bulleted paragraphs The HNP RPV was originally fabricated with clad feedwater nozzles with interference fit spargers. The original nozzle configuration is shown on CE drawing E 234-274 which can be found in the Hatch 1 Reactor Vessel Instruction Manual (S-19000). Because of cracking issues at other sites associated with the original configuration, the HNP-2 nozzle cladding was removed and a triple-sleeve, double piston sparger was installed per DCR 78-202. New feedwater nozzle configurations are shown in drawings SX-18920 and SX-18921.
| |
| Edwin I. Hatch Nuclear Power Station, Unit 1, Feedwater Fracture Mechanics Analysis to Show Compliance with NUREG-0619 (NEDE-30238) was issued on August 1983 and submitted to the NRC by letter dated September 19, 1984.
| |
| By Safety Evaluation dated January 21, 1986 the NRC concluded that during the forty year life, the amount of fatigue crack growth in the feedwater nozzles should be less than one inch, therefore, the existing Unit 1 flow controllers are in compliance with NUREG-0619 as amended by Generic Letter 88-11. Once compliance was determined, NUREG-0619 required (for the new triple-sleeve, double piston configuration) that a UT examination be performed on all feedwater nozzle bores and inside blend radii every 2nd refueling outage and a PT of the ID be performed every 6 refueling outages or 135 startup/shutdown cycles.

| Hatch Basis Doc Aug Other.doc Page 2 of 6 Rev. 1
| |
| | |
| FOURTH INTERVAL AUGMENTED OTHER PLAN HATCH UNIT NO. 2 By letter dated October 19, 1992, SNC proposed to perform an automated UT during the Spring 1993 outage and then UT every 4th refueling outage in lieu of the NUREG-0619 requirements. The PT examination would thus be eliminated.
| |
| By NRC Safety Evaluation dated 10/21/94 and by SNC 10 CFR 50.59 Safety Evaluation dated 9/28/95 (HL-5040), the PT examination was eliminated and the frequency of the UT examinations was changed to every 4th refueling outage.
| |
| Because of significant advances in UT inspection technology in the 1990s, the BWROG (using GE) began the development of alternate inspection requirements for the feedwater nozzles. As a result, BWROG Licensing Topical Report, Alternate BWR feedwater Nozzle Inspection Requirements, (GE-NE-523-A71-0594, Revision
| |
| : 0) was issued in October 1995 to allow reduced inspection frequencies.
| |
| A report were prepared by GE in July 1997 for HNP-2 as part of the Extended Power Uprate effort, which (in part) provided feedwater nozzle fracture mechanics assessments based upon the existing low flow feedwater controller in conjunction with plant operating history available at the time. The Extended Power Uprate increased the nominal operating pressure by about 50 psi and the feedwater nozzle temperature about 60 F.
| |
| On February 9, 2000, GE issued a plant specific evaluation for HNP to provide justification for extending the UT examination frequency of the nozzle inner radii and elimination of the ID PT examination. The evaluation was based on Revision 0 of the BWROG Topical Report and the NRC Safety Evaluation dated June 5, 1998. The evaluation noted that Revision 1 of the Topical Report, which incorporated responses to six NRC criteria, was submitted to the NRC on September 24, 1999. The evaluation further noted that the NRCs approval of the September 24th submittal would have no effect on the evaluation. Key issues and results are:
| |
| * The evaluation per the BWROG Topical Report included consideration of the sparger type (triple-sleeve, double piston), UT inspection methodology (automated, full RF recording), and crack growth rate (based on the 1997 Extended Power Uprate feedwater nozzle fracture mechanics analysis).
| |
| * The 1997 Extended Power Uprate feedwater nozzle fracture mechanics was used in determining the length of time that it would take to grow a 0.25 crack to unacceptable limits. Two criterion were used.
| |
| : a. The first criterion was the time that it would take to grow the 0.25 crack to 1 in depth, which was the criteria found in NUREG-0619. It was concluded by the analysis that a crack would take greater than 40 years to grow to a depth of 1 and that it would reach 0.87 in depth in 36 years.
| |

| |
| | |
| FOURTH INTERVAL AUGMENTED OTHER PLAN HATCH UNIT NO. 2
| |
| : b. The second criterion is more limiting and was based on the time it would take to grow a 0.25 crack to 10% of the blend radius thickness, which is the acceptable flaw depth per ASME Section XI. The blend radius was calculated by GE as 7.6 thick; therefore, the acceptable flaw depth would be 0.76. The time to grow a 0.25 crack to 0.76 deep was determined to be 32 years. GE indicated than a 10-year inspection frequency is appropriate based on the Extended Power Uprate fracture mechanics evaluation, a triple-sleeve, double-piston configuration, automated - full RF recording UT, and a blend radius thickness of 7.6.
| |
| On March 13, 2000 a letter was issued from D. M. Crowe (HNP Licensing Manager) to B. K. McLeod concluding that General Electric had performed the evaluation to change the inspection frequency to once per 10 years. The change was implemented per a 10 CFR 50.59 Evaluation dated 3/13/00.
| |
| In May 2000 GE issued, Alternate BWR feedwater Nozzle Inspection Requirements, GE-NE-523-A71-0594-A, Revision 1, which incorporated the NRCs safety evaluation.
| |
| By letter dated September 23, 2003, the NRC approved the change to increase licensed power level for Hatch, Units 1 and 2 by 1.5 percent from 2763 megawatts thermal (MWt) to 2804 MWt. In the RPV Structural Evaluation portion of the safety evaluation it is stated that, The proposed power uprate does not change the operating reactor pressure and temperature from the current operating condition. Therefore, this change should not affect the fracture mechanics evaluation performed after the Extended Power Uprate.
| |
| Per Table 6-1 of GE-NE-523-A71-0594-A (NRC approved Alternate BWR Feedwater Nozzle Inspection Requirements) the Required Time between UT examinations of the Feedwater may be calculated as the Allowable Time multiplied by a Factor which is based on the sparger configuration and the type of UT examination. HNP-2 has a triple sleeve, double piston sparger configuration and uses automated - full RF recording UT.
| |
| For an Allowable Time of 32 years the Required Time is 32 X 0.33 or 10.6 years ( 10 years). However, Note 2 of Table 6-1 indicates that a 10-year frequency is the maximum time between inspections for the blend radius area (region 1) and a portion of the nozzle bore (Region 2). Therefore, 10 years will be used as the frequency of examinations.
| |
| On December 3, 2003, discussions were held with Gary Stevens of Structural Integrity Associates. Per Gary Stevenss August 9, 1999 E-Mail (and reconfirmed during the 12/3/03 call) the use of 10% of wall thickness allowable flaw size for feedwater nozzles is based on Subsection IWB-3611 which permits an allowable flaw size of 10% of the critical size for normal operating conditions. In the case of the feedwater nozzle, the critical flaw size can be shown to be greater than the wall thickness, so the critical flaw size is set equal to the wall thickness, t. Thus, 0.10
| |
| * t is used for the allowable flaw size.
| |
| It was confirmed that the blend radius was the most limiting area for crack growth; Hatch Basis Doc Aug Other.doc Page 4 of 6 Rev. 1
| |
| | |
| FOURTH INTERVAL AUGMENTED OTHER PLAN HATCH UNIT NO. 2 therefore, GEs selection of 10% of the blend radius and a 10-year examination frequency was appropriate. Therefore, because the scheduling is the same as Code frequency these examinations will be treated as Category B-D, Item 3.100 Code examinations in ScheduleWorks. The only difference is that they are referred to as Nozzle Inner Radius and Bore examinations.
| |
| These welds are designated as Category B-D welds in the Class 1 portion of this document.
| |
| CRD Return Line NUREG-0619 also addressed the examination of the Thermal Mixing Tee where CRD is routed to Feedwater. In this case, water from CRD mixes with RWCU at the mixing tee.
| |
| There is a potential for cracking in the mixing zone. Therefore, the downstream thermal tee weld (2G31-2RWCU-4-2FW-33) is examined. This examination is not addressed in GE-NE-523-A71-0594-A; therefore, it will be continued each outage as required by NUREG-0619.
| |
| This weld is designated as Category C-0619 in Schedule Works in this portion of the plan.
| |
| Class 2 Thin-Wall Piping The NRCs safety evaluation dated 6/16/97 of the 3rd Interval Program also indicated, that in addition to the 1989 Code required examinations, volumetric examination of a 7.5% sample of a portion of thin-wall, non-exempt piping within the RHR, CS, and HPCI systems would be performed. See Class 2 Augmented for a detailed evaluation.
| |
| These welds are designated as Category C-0803 in Schedule Works in this portion of the plan.
| |
| RCIC Additionally, portions of the Reactor Core Isolation Cooling are designated as Class S on Boundary Diagram HB-16334 and HB-16335. It will be treated using Section XI as a guideline (not as a requirement). As discussed for the Class 2 portion of this piping, this system does not have an RHR, ECC, or CHR function; therefore, the size exemption and the pressure/temperature exemption will also be used for this Class S piping. Lines within Class S were evaluated below for examination potential.
| |
| 6 Suction Line from the Condensate Storage Tank (Designated as 1E51-2RCIC-6PS-1 thru 24 on Figure B-88 and listed as Category CF-R in Schedule Works). This piping is pressure/temperature exempt because it is at static pressure and ambient temperature; therefore, examination of piping welds, integrally welded attachments, and supports is not required.
| |
| Hatch Basis Doc Aug Other.doc Page 5 of 6 Rev. 1
| |
| | |
| FOURTH INTERVAL AUGMENTED OTHER PLAN HATCH UNIT NO. 2 6 Suction Line from valve 1E51-F031 through valve 1E51-F029 (Designated as 1E51-2RCIC-6TS-10, 11, 12, 13, and 14 on Figure B-89 and listed as Category CF-R in Schedule Works). This piping is pressure/temperature exempt because it is highly unlikely that it would ever exceed the prescribed pressure/temperature. Therefore, examination of piping welds, integrally welded attachments, and supports is not required.
| |
| 4 Pump Discharge Line - This piping is size exempt; therefore, examination of piping welds, integrally welded attachments, and supports is not required. (Not shown in Schedule Works).
| |
| 4 (and less) Steam Supply - This piping is size exempt; therefore, examination of piping welds, integrally welded attachments, and supports is not required.. (Not shown in Schedule Works).
| |
| 10 Steam Exhaust from the turbine to valve 1E51-F040 (Designated as 1E51-2RCIC-1 thru 24 and shown as Category CF-R in Schedule Works). This piping is shown on Figures B-24 and B-25 and is not pressure/temperature exempt because of the steam conditions. However, all of this piping is 0.365 nominal wall thickness and therefore does not require examination of the piping welds. The welded attachments and supports on this line are not subject to examination.
| |
| As discussed above, when applying Section XI requirements to Category S RCIC there are no requirements for examination. However, RCIC is an important system when considering PRA; therefore, a small sample of welds (designated as Category CF-R),
| |
| Category supports (designated as Category FA-R), and welded attachments (designated as Category CC-R) were selected.
