Subject:
Brunswick Steam Electric Plant, Unit Nos. 1 and 2 Docket Nos. 50-325 and 50-324/License Nos. DPR-71 and DPR-62 Proposed Alternative for the Third 10-Year Inservice Inspection Program Ladies and Gentlemen:
This letter submits arequest, in accordance with 10 CFR 50.55a(g)(5)(iii), to use a proposed alternative to the applicable edition of the American Society of Mechanical Engineers (ASME) Code,Section XI for the Brunswick Steam Electric Plant (BSEP),
Units 1 and 2, on the basis that compliance with the specified requirements is impractical due to plant design. Carolina Power & Light Company (CP&L), now doing business as Progress Energy Carolinas, Inc., is submitting this relief request for ASME Code,Section XI control rod drive housing weld examinations performed during the third 10-year inservice inspection interval where the inspection coverage achieved was less than 100 percent due to physical obstructions and geometric interferences.
The relief request supports the third 10-year inservice inspection interval for both BSEP, Unit 1 and Unit 2. The third 10-year inservice inspection interval began on May 11, 1998.
As allowed by sub-article IWA-2430(d) of the ASME Code,'Section XI, the third 10-year inspection interval for Unit 2 was extended for one year. This extension enabled the examination of Unit 2 components to coincide with the B219R1 refueling outage, which began February 28, 2009. As such, the third 10-year inspection interval for BSEP, Unit 2 will conclude on May 10, 2009, and the third 10-year inspection interval for BSEP, Unit 1 concluded on May 10, 2008.
CP&L requests approval of this relief request by April 30, 2010.

- Inservice Inspection Impracticality -
- 1. ASME Code Components Affected Code Class: I
References:
Subarticle IWB-2500, Table IWB-2500-1 Examination Categories: B-O, "Pressure Retaining Welds in Control Rod Housings" Item Numbers: B 14.10, "Welds in CRD Housing"
Description:
Volumetric Examination Coverage Component Numbers: ICI 1-CRD06-11-SW1 CRD Housing Weld ICI I-CRD06-15-SWI CRD Housing Weld IC II -CRD 10-07-SW I CRD Housing Weld IC 11 -CRD 14-07-SW 1 CRD Housing Weld 2C1 1-CRD38-47-SW1 CRD Housing Weld 2C 1 I-CRD42-47-SW1 CRD Housing Weld 2C 11-CRD46-39-SWl CRD Housing Weld 2C 11-CRD46-43-SW1 CRD Housing Weld
2. Applicable Code Edition and Addenda
The Inservice Inspection Program for the third 10-year inservice inspection interval was based on the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section XI, 1989 Edition with no Addenda.
3. Applicable Code Requirement
Sub-article IWB-2500, Table IWB-2500-1, requires essentially 100 percent volumetric or surface examination of 10 percent of the peripheral control rod drive (CRD) housing welds (Examination Category B-O, Item No. B14.10, as defined by Figure IWB-2500-18).
Carolina Power & Light Company (CP&L), now doing business as Progress Energy Carolinas, Inc., elected to perform surface examinations on the selected CRD housing welds.
- 4. Impracticality of Compliance In accordance with 10 CER 50.55a(g)(5)(iii), relief is requested from the requirement of the ASME Code,Section XI, Sub-article IWB-2500, Table IWB-2500-1 (Volumetric or Surface
BSEP 09-0043 Enclosure Page 2 of 8 Examination Category B-O, "Pressure Retaining Welds in Control Rod Drive Housings"),
Examination Item Number B 14.10, "Welds in CRD Housing." Limited accessibility for the 36 peripheral CRD housing welds is due to the close proximity of adjacent CRD housing flanges, neutron monitoring instrumentation and associated cabling, and horizontal beams, support bars and grids.
- 5. Burden Caused by Compliance Compliance with the examination coverage requirements of the ASME Code,Section XI, would require modification, redesign, or replacement of components where geometry is inherent to the component design.
- 6. Proposed Alternative and Basis for Use Proposed Alternative In accordance with 10 CFR 50.5 5a(g)(5)(iii), CP&L is requesting relief for the components listed above on the basis that the required examination coverage of "essentially 100 percent" is impractical due to physical obstructions and severely limited access in the work area. As an alternative, CP&L proposes selecting the four. additional upper CRD housing welds, listed" below, in lieu of the four lower housing-to-flange welds. This would provide the same total number of CRD housing welds for examination (i.e., eight welds) and will be an equivalent 100 percent inspection of 10 percent of the peripheral housings.
Unit 1 Additional CRD Unit 2 Additional CRD Housing Weld Examinations Housing Weld Examinations 1C 11-CRD38-47-SW2 2C 11-CRD06-11 -SW2 IC 11-CRD42-47-SW2 2C 11-CRD06-15-SW2 IC 11-CRD46-39-SW2 2C 11-CRD1O-07-SW2 iC 11-CRD46-43-SW2 2C 11-CRD 14-07-SW2 Basis for Use The ASME Code,Section XI, Sub-article IWB-2500, Table IWB-2500-1, requires essentially 100 percent volumetric or surface examination of 10 percent of the peripheral CRD housing welds (Examination Category B-O, Item No. B 14.10, as defined by Figure IWB-2500-18).
Each CRD housing contains two pressure retraining welds. Table IWB-2500-1 requires both the upper and lower welds of each of the selected CRD housings to be examined.
BSEP 09-0043 Enclosure Page 3 of 8 BSEP has 36 peripheral CRD housings; therefore, this requires four CRD housings (i.e., a total of eight CRD housing welds) to be examined. As previously stated, each CRD housing contains two pressure retaining welds: the housing-to-flange weld and the housing tube-to-tube weld. The housing-to-flange weld is located in the inaccessible lower section of the CRD housing, whereas the housing tube-to-housing tube weld is located in the accessible upper section of the CRD housing (i.e., shown on Drawings 0-FP-05609; C-24004, Sheet 26-1; and C-02404, Sheet 26-1; provided in Attachments 1, 2, and 3, respectively).
Limited access for the 36 peripheral CRD housing-to-flange weld welds is due to the work area under the reactor vessel being highly congested, as shown in the photographs in . Physical obstructions imposed by design, geometry, and materials of construction include vessel appurtenances, insulation support rings, structural and component supports, adjacent CRD housing flanges, and neutron monitoring instrumentation and associated cabling. These obstructions are not practical to remove or replace to achieve 100 percent volumetric or surface coverage of the welds in the CRD housings. The upper housing welds are without obstruction and can be completely examined.
Therefore, as an alternative, CP&L proposes selecting four additional upper CRD housing welds in lieu of the four lower housing-to-flange welds. This would provide the same total number of CRD housing welds for examination (i.e., eight welds).
CP&L performed qualified surface examinations that achieved the maximum, practical amount of coverage obtainable within the limitations imposed by the design of the components. The examinations conducted confirmed satisfactory results, with no unacceptable flaws being identified and no evidence of degradation mechanisms.

This was completed during the Unit 1 2008 refueling outage (i.e., the BI 17R1 outage) and Unit 2 2009 refueling outage (i.e., the B219R1 outage), and no evidence of leakage was identified for these components. Reactor coolant system leak rate limitations and atmospheric particulate radioactivity monitoring also ensure that any leakage would be detected prior to gross failure.

- 7. Duration of the Proposed Alternative Use of the proposed alternative is applicable to the third 10-year inservice inspection interval at BSEP, Units 1 and 2. The third 10-year interval began on May 11, 1998, and ended on May 10, 2008, for Unit 1 and will end on May 10, 2009, for Unit 2.
- 8. Precedents Similar relief request was granted for the Pilgrim Nuclear Power Station, as listed in Reference 1.
