BROWNS FERRY NUCLEAR PLANT (BFN) UNIT 2 AMERICAN SOCIETY OF MECHANICAL ENGINEERS (ASME) SECTION XI, INSERVICE INSPECTION 'RELIEF REQUEST 2 S 6 r REVIS ION 1 II In accordance with 10 CFR 50.55a(g)(5)(iii), TVA is requesting relief from specified inservice inspection requirements in Section XI of. the ASME Boiler and Pressure Vessel Code, 1986 Edition (no addenda). The enclosure to this letter submits request for relief 2-ISI-6, Revision 1 for NRC review and approval.
TVA has determined that 20 components have non destructive examination (NDE) coverage limitations (90 percent or less coverage completed) which exceeds that specified in ASME Code Case N-460, "Alternative Examination Coverage for Class 1 and Class 2 Welds,Section XI, Division 1.n The components are 19 reactor pressure vessel (RPV) nozzle-to-vessel welds and one nozzle inside radius section (ASME Section XI, Code Category B-D, nozzle-to-vessel welds). The calculated NDE coverage completed varied for each component, ranging between 52 and 77 percent. The limitations encountered during the performance of the ultrasonic (UT) examination were caused by component configuration and structural design. The nozzle contours and the proximity of the biological shield wall limits access to the required weld volume and nozzle inside radius section.

REQUEST FOR RELIEF 2-ISI-6, REVISION 1 Re uest For Relief 2-ISI-6, Revision 1 Executive Summar This request for relief addresses 19 Reactor Pressure Vessel (RPV) nozzle-to-vessel full penetration welds and one nozzle inside radius section. The design configuration of the RPV nozzle-to-vessel welds and the small diameter instrumentation nozzle (4-inch) precludes a 100 percent ultrasonic examination of the required volume for the full penetration welds and the nozzle inside radius section of the components listed in Table 1. These examination limitations occur when the ASME Section XI, 1986 Edition, no Addenda, examination requirements are applied in areas of components constructed and fabricated to early plant designs. Based on a construction permit date prior to January 1, 1971, BFN is exempt from meeting certain provisions of the code requirements for examination access, to the extent practical, within the limitations of design, geometry, and materials of construction of the components in accordance with 10 CFR 50.55a(g)(4).
An ultrasonic examination was performed on accessible areas to the maximum extent practical given the physical limitations of the subject welds and the inside corner region. The design configuration limits ultrasonic examination of the RPV nozzle-to-vessel welds and inside corner region to the percentages shown in Table 1. TVA concludes that performance E-2
Re uest For Relief 2-ISI-6, Revision 1 (continued) of an ultrasonic examination of essentially 100 percent of the RPV nozzle-to-vessel full penetration welds and the inside corner region of one 4-inch nozzle would be impractical. The performance of the ultrasonic examination of the subject areas to the maximum extent practical provides an acceptable level of quality and safety because the information and data obtained from 0he volume examined provides sufficient information to judge the overall integrity of the welds and inside corner region. Therefore, pursuant to 10 CFR 50.55a(g)(5)(iii), it is requested that relief be granted for the second inspection interval.

The component design configuration limits ultrasonic examination coverage of the welds to the percentages listed in Table l.

Re uest For Relief ISI-2-6, Revision 1 (continued)
The design configuration of the small diameter (4-inch) instrumentation nozzle; the ASME Section XI, 1986 Edition, no addenda, requirement for the examination coverage to extend from the inside radius section along the nozzle bore axis to a distance equal to the vessel wall thickness; and the short weld blend radius on the vessel outside surface, preclude an ultrasonic examination of essentially 100 percent of the required volume. The component design configuration limits ultrasonic examination coverage of the inside corner region to the percentage listed in Table 1.
Alternative Examination: None. In lieu of the Code required essentially 100 percent volume ultrasonic examination, TVA proposes an ultrasonic examination of accessible areas to the maximum extent practical given the component design configuration of the RPV nozzle-to-vessel welds and nozzle size.
Justification For The Grantin Of Relief: (1) The design configuration of the subject nozzle-to-vessel welds precludes ultrasonic examination of essentially 100 percent of the required examination volume. Access to the vessel-to-nozzle welds is by a series of doorways in the concrete biological shield wall.
Insulation behind these doorways is designed for removal around the nozzle circumference. In order to examine the welds in accordance with the Code requirement the RPV would require extensive design modifications. The physical arrangement of the nozzle-to-vessel weld precludes ultrasonic examination from the nozzle side. The limitations are inherent to the barrel-type nozzle-to-vessel weld design and is compounded by the close proximity of the biological shield wall.

Re uest For Relief 2-ISI-G, Revision 1 (continued)
Scanning from the nozzle surface is ineffective due to the weld location and the asymmetrical inside surface where the nozzle and vessel converge. Coverage was increased by scanning from the outside blend radius of the weld where practical.
Experience from the automated ultrasonic examination performed from the inside surface on BFN Unit 3, which is of similar design, has shown that the nozzle-to-vessel weld coverage will not be greatly improved even if performed from the inside surface utilizing the current state-of-the-art techniques, The configuration of the nozzle-to-vessel welds precludes ultrasonic examination from the nozzle side due to the weld location and the asymmetrical inside surface where the nozzle and vessel converge. The extent of examination coverage from the vessel side provides reasonable assurance that no flaws oriented parallel to the weld are present. In addition, approximately 100 percent of the required ultrasonic examination volume for flaws oriented transverse to the weld was performed from the vessel side.
The design configuration of the small diameter (4-inch) instrumentation nozzle precludes ultrasonic examination of essentially 100 percent of the nozzle inside radius section due to the short weld blend radius on the vessel outside surface. The examination volume successively examined included the most highly stressed area of the nozzle inside surface region. The area that received no coverage was the required volume of the nozzle bore at the greatest radial distance from the vessel center-line where the stress concentrations are less than the stresses in the areas where examination coverage was obtained. The

Re uest For Relief 2-ISI-6, Revision 1 (continued) examination coverage obtained provides reasonable assurance that no flaws are present.
(2) Radiographic examination as an alternate volumetric examination method was determined to be impractical due the radiological concerns. Gaining access to the inside surface of the RPV to place radiographic film would require extensive personnel protection due to high radiation and contamination levels.
Also, due to the varying thickness at the outside blend radius of the weld several radiographs may be required of one area to obtain the required coverage and/or film density. The additional Code coverage gained by radiography is impractical when weighed against the radiological concerns.
Therefore, TVA concludes that performing an ultrasonic volumetric examination of essentially 100 percent of the nozzle-to-vessel full penetration welds in the RPV would be impractical. Further, it would also be impractical to perform other volumetric examinations (i.e.,
radiography) which may increase examination coverage. A maximum extent practical ultrasonic examination of the subject areas provides an acceptable level of quality and safety. TVA concludes that significant degradation, if present, would have been detected during an ultrasonic examination performed to the maximum extent practical of the subject welds and inside corner region. As a result, reasonable assurance of operational readiness of the subject welds has been provided.
Therefore pursuant to 10 CFR 50.55a(g)(5)(iii), TVA requests that relief be granted for the second inspection interval.

Im lementation This request for relief is applicable to Schedule: the second inspection interval for BFN Unit 2. The nozzle-to-vessel welds and one nozzle inside radius section listed in Table 1 were examined either during the first or second period (Cycle 7 and 9 respectively) of the second ten year inspection interval.

Automated UT examinations were performed in accordance with UT-BFN-702VO Rev. O. The Manual UT examinations were performed in accordance UT-BFN-300VO Rev. 0.
Automated UT examinations were restricted due to the bioshield. The Manual UT examinations were restricted due to a thermo-couple.
The GERIS system recorded the following nonrelevant indications:
0 L-wave - clad noise 45 T-scan - entry surface noise 604 T-scan - entry surface noise, clad noise 454 T-scan ODBR - entry surface noise, clad noise, nozzle geometry 604 T-scan ODBR - entry surface noise, nozzle geometry 45 P-scan - entry surface noise 604 P.scan - entry surface noise These nonreievant indications were flagged and excluded from the final reports.
No indications requiring evaluation per ASME Code Section XI and Reg. Guide 1.150 were recorded.
The Automated UT and Manual UT composite coverage EE 60.32% code credit taken.
Due to the nozzle to vessel weld design it is not feasible to effectively ultrasonically examine 100% of the ASME Code examination volume as defined in Section XI.
