Exelon Generation www.exeloncorp.com 4300 Winfield Road Warrenville, I L 60555 RS-04-104 July 22, 2004 U.S. Nuclear Regulatory Commission ATTN : Document Control Desk Washington, DC 20555-0001 Subject : Second Interval Inservice Inspection Program Relief Request 12R-46 In accordance with 10 CFR 50.55a, "Codes and standards," paragraph (a)(3)(i), Exelon Generation Company, LLC (EGC), is requesting relief from the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section XI, "Rules for Inservice Inspection of Nuclear Power Plant Components," on the basis that the proposed alternative provides an acceptable level of quality and safety.
Specifically, this proposed alternative would allow Byron Station to use ASME Code Case N-652, "Alternative Requirements to Categories B-G-1, B-G-2, and C-D Bolting Examination Methods and Selection Criteria," in lieu of the ASME Code,Section XI, 1989 Edition requirements for class 1 and 2 bolting examination methods. The details of the request for relief are enclosed.
EGC requests approval of this request by February 2005 in order to support the Byron Station, Unit 1 refueling outage scheduled to start March 1, 2005. Should you have any questions concerning this letter, please contact David J. Chrzanowski at (630) 657-2816.
Respectfully, Byron Station, Units 1 and 2 Facility Operating License Nos. NPF-37 and NPF-66 NRC Docket Nos. STN 50-454 and 50-455 Kenneth A. Ainger Manager, Licensing Attachment : 10 CFR 50.55a Relief Request 12R-46 10 CFR 50.55a
BYRON STATION UNITS 1 and 2 Request for Relief for Alternative Requirements to the ASME Code Section X1 Class I and 2 Bolting Examination Methods and Selection Criteria In Accordance with 10 CFR 50.55a(a)(3)(i)

All Unit 1 and Unit 2 drawings with components applicable to these categories (See Table 2 for Complete Listing)
The current inservice inspection program is based on the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code,Section XI, 1989 Edition with no Addenda.
3. APPLICABLE CODE REQUIREMENTS Table IWB-2500-1, Examination Categories B-G-1 "Pressure Retaining Bolting, Greater Than 2 Inches in Diameter," and B-G-2, "Pressure Retaining Bolting, 2 Inches and Less in Diameter," and Table IWC-2500-1 Examination Category C-D, "Pressure Retaining Bolting, Greater Than 2 Inches in Diameter," contain requirements for the selection, scheduling, and examination of component bolting. Specific requirements are identified for each item number within these categories.
As an alternative to the ASME Code, 1989 Edition,Section XI requirements, EGC requests NRC approval to use ASME Code Case N-652, "Alternative Requirements to Categories B-G-1, B-G-2, and C-D Bolting Examination Methods and Selection Criteria." Use of Code Case N-652 will supplement the 1989 Edition,Section XI requirements in the areas of examination methods, selection criteria, and scheduling of examinations.
The 1989 Edition is not specific in the subject of selection and scheduling requirements for all of the components in these categories. Use of the code case will clarify these requirements.
Use of Code Case 1`0652 will reduce the radiological dose during an outage by :
- a.
limiting examinations to a single component in a group that are similar in design, type, and function ;
BYRON STATION UNITS I and 2 SECOND INTERVAL ISI PROGRAM PLAN 10 CFR 50.55a RELIEF REQUEST 12R-46 Revision 0 (Page 2 of 16)
- b.
eliminating highly restrictive examinations on in-place components (the bolting components may be examined after removal) ; and
- c.
eliminating redundant examinations of components that are repeatedly disassembled during the interval (this would include flange surfaces).
Use of Code Case N-652 will reduce the time and examination costs during an outage by:
- a. eliminating multiple examinations on Class 1 closure head studs and
- b. allowing the use of surface methods on bolting that have complex shapes which are not readily examined using field volumetric methods.
In addition, portions of the ASME Code, 1989 Edition, requirements for examination of Class 1 bolting are duplicated by examinations performed for other programs such as the examination of the bolted connection of components containing borated fluids and the pressure test programs.
The highlighted items in Table 2 of this request identify fifty-nine component numbers at Byron Station that would benefit from the alternative examination rules of ASME Code Case N-652.
Given that these component numbers are typically composed of multiple examination points (for example, the reactor vessel close stud component number consists of 58 studs that each require examination), the radiation dose savings during an outage can be significant. However, quantification of the radiation dose savings is difficult since the components cover a variety of plant locations all subject to varying radiation dose fields. The radiation dose impact also depends on the degree of required examination support (e.g., scaffolding, insulation removal) and the duration of the examination (i.e., volumetric, surface, or visual).
- 5. PROPOSED ALTERNATIVE AND BASIS FOR USE In accordance with to 10 CFR 50.55a(a)(3)(i), relief is requested on the basis that the proposed alternative will provide an acceptable level of quality and safety. Examinations of Class 1 and 2 bolting will substitute the requirements of the current 1989 Section XI programs with the alternatives presented in ASME Code Case N-652. The changes using this code case are divided into three areas as follows.
A.
Examination Methods of Components in Examination Categories B-G-1 and C-D Use of visual methods of closure head nuts :
The ASME Code, 1989 Edition, of Section XI Table IWB-2500-1 does not list the examination requirements/figure numbers or the acceptance standards for Item B6.10. Itstates ina footnote that these requirements are "in course of preparation." Code Case N-627 was published by the ASME allowing the substitution of surface examination methods with visual methods. This code case was approved for use by the NRC in Regulatory Guide 1.147, Revision 13. However, Code Case N-627 does not specify the examination areas or acceptance standards. This missing information regarding the examination areas and acceptance standards for the closure head nuts is supplied in (lode Case N-652.
Elimination of the distinction of in-place and removed closure head studs:
Closure head studs require a volumetric examination whether the studs are removed or remain in-place. Item Numbers B6.20 (in-place) and B6.30 (removed) were combined into a
BYRON STATION UNITS 1 and 2 SECOND INTERVAL ISI PROGRAM PLAN 10 CFR 50.55a RELIEF REQUEST 12R-46 Revision 0 (Page 3 of 16) single item 86.20 in Code Case N-652 and the additional surface examination is optional for removed studs. The surface method may replace the volumetric method for removed studs per Note (2). The option of surface or volumetric examinations for closure head studs is incorporated in later editions of the ASME Code and these later editions have been endorsed in 10 CFR 50.55a.
Use of surface methods as an alternative to volumetric examinations :
For bolting of components other than reactor vessels, (136.60, 86.90, B6.120, 86.150, 86.180, 86.210, and all of Class 2 Category C-D) a surface examination may also be substituted for the volumetric method per B-G-1 Note (2) and C-D Note (2). This change makes the examination requirements consistent for all bolting components greater than 2 inches in diameter. The option to use surface methods in lieu of volumetric methods also facilitates examination of studs and bolts with complex shapes that are not easily examined using field volumetric techniques.
B. Selection Criteria for Various Components Heat exchangers, pumps, and valves :
Code Case N-652, Category B-G-1 Notes (4 and 5) and Category B-G-2 Note (2) clarify the selection requirements for these components to reflect the selection requirements of the associated vessels (B-B), pumps (B-L-2), and valves (B-M-2). This modifies the criteria specified in the 1989 Edition of the ASIVIE Code, Category B-G-1, Note (3) that stated the examinations are limited to those components selected under the other categories. These other categories divided the components into groups based on size, design, and function.
Code Case N-652 now includes the corresponding conditions in the selection of the bolting for these components. This criterion is unchanged in Category C-D.
Piping flange components :
Code Case N-652, Category B-G-1 Note (6) and Category B-G-2 Note (3) added the selection requirements that these components may be divided into groups based on size, design, and function and that the examination may be limited to one component within the group. This establishes a grouping criteria similar to the one used for heat exchangers, pumps, and valves. In addition, the 1989 Edition of the ASIVIE Code required that the examinations are limited to those components selected for examination under the piping Category B-J for Class 1 and Category C-F for Class 2. The 1989 Edition of the ASME Code definition of component as it applies to Categories B-J and C-F is unclear. Byron Station has conservatively applied this condition to select all piping flanges within the Class 1 piping boundary. Byron Station has also adopted risk-informed inservice inspection using Code Case N-578-1. Use of Code Case N-578-1 eliminates examination categories B-J and C-F. Code Case N-652 establishes a selection criterion without using these category references.
C. Scheduling Changes with N-652 Deferral of examination for B-G-1 Components :
The 1989 Edition of the ASME Code has Note (5) allowing deferral to the end of the interval if no leakage of borated water is detected. This note applied to all items in the category. Code Case N-652 replaced this note by allowing a deferral for all components. Subsequently, the
BYRON STATION UNITS 1 and 2 SECOND INTERVAL ISI PROGRAM PLAN 10 CFR 50.55a RELIEF REQUEST 12R-46 Revision 0 (Page 4 of 16) allowance of this deferral results in a conclusion that examination of B-G-1 components need only be performed once in the inspection interval.
B-G-1 Visual Examinations of Heat Exchanger, Pumps, and Valves :
Code Case N-652 clarifies that for components that are disassembled the examination need only be performed once in the interval. Some components such as steam generator manway bolting may be disassembled more than once in an inspection interval and the clarification by Code Case N-652 will eliminate redundant examinations of these components.
In-place examinations of B-G-2 components :
Code Case N-652 eliminates visual examinations of in-place, under tension, bolting components. These examinations are highly limited in access to all of the required surfaces for the visual examination. These assembled components are also VT-2 examined once per outage for the insulated borated bolted connections where applicable per IWA-5242(a) and all are examined for the VT-2 examination performed at nominal pressure and temperature. If leakage occurs at a bolted connection, the bolting shall be removed for visual examination under both category B-G-2 and IWA-5250(a)(2).
Code Case N-652 does not specify use of specific ASME Code editions or addenda. Code Case N-652 is applicable for the 1977 Edition of the ASME Code through the 1998 Edition with the 2000 Addenda. The ASME Code,Section XI is endorsed through the 2000 Addenda as documented in 10 CFR 50.55a(b)(2). With respects to personnel and equipment certifications, details of examination techniques, and applicable examination figures and acceptance standards, EGC will use the applicable portions of the 1989 Edition of the ASME Code.
The proposed alternative will provide an acceptable level of quality and safety given that :
A. The alternative approach was produced within the ASME organization.
B. Alternative examination methods are as capable of detecting service-induced flaws as the original methods.
C. Alternative selection and scheduling criteria clarify the original examination categories and are supplemented by additional activities from other portions of Section XI.
EGC proposes to substitute the requirements of the ASME Code, 1989 Edition, of Section X1 for examination categories B-G-1, B-G-2, and C-D with the alternative requirements presented in ASME Code Case N-652.
- 6. DURATION OF PROPOSED ALTERNATIVE This relief request will be implemented during the remainder of Byron Station, Units 1 and 2 second ten-year inservice inspection interval or until the NRC approves Code Case N-652 in a future revision of the applicable Regulatory Guide during the current inspection interval.
- 7. PRECEDENTS There are no precedents in the form of relief requests, however, as highlighted in Table 1 of this request, several aspects of Code Case N-652 have been incorporated into those ASME Code Section XI editions already approved by the N RC in 10 CFR 50.55a{b}(2).
