REQUEST FOR ADDITIONAL INFORMATION TURKEY POINT UNITS 3 AND 4 RELIEF REQUEST NOS. 1A, 14A, AND 15A DOCKET NOS. 50-250 AND 50-251 General

1. Relief Requests 1A, 14A and 15A indicated that the third 10-year inservice inspection (ISI) interval ended February 21, 2004, for Unit 3 and April 14, 2004, for Unit 4. By letter dated October 20, 2004, the NRC authorized extension of the third 10-year interval to February 21, 2005, for Unit 3 and to April 14, 2005, for Unit 4. Please indicate the proper end dates for the Unit 3 and Unit 4 third 10-year ISI intervals.

Relief Request 1A:

2. In Florida Power and Light Company (FPL) letter dated February 20, 2006, it is stated the objective of Relief Request 1A is to resubmit the previously approved Relief Request No.1. The request also states that this revision submits the examination volume coverage obtained during the third 10-year ISI interval inspection. In comparing Relief Request 1 with Relief Request 1A, the upper shell-to-flange weld is included in both requests. Welds 3-DO-A, 3-DO-B, 3-DO-C, 4-DO-A, 4-DO-B, 4-DO-C are included in Relief Request 1, but they are not included in relief request 1A. Relief Request 1A contains additional examinations that had limited coverage, welds 3-WR-9 and 4-WR-9 and the 1-inch annular surface of flange surrounding each reactor vessel stud hole.

Does Relief Request 1A supersede Relief Request 1, or is it in addition to Relief Request 1? If Relief Request 1A is to supersede Relief Request 1, was essentially full coverage obtained on welds 3-DO-A, 3-DO-B, 3-DO-C, 4-DO-A, 4-DO-B, 4-DO-C? If Relief Request 1A is to be in addition to Relief Request 1, is the request for relief with regard to welds 3-WR-18 and 4-WR-18 any different than the request for relief made under Relief Request 1 (other than 71-percent coverage was obtained vs. 68-percent projected)?

3. Relief Request 1A states that the examination of the Figure1 IWB-2500-12 A-B-C-D-E-F-G-H volume is limited when scanning the carbon steel base material surrounding the stud holes due to the sealing surfaces configuration. Please explain how the sealing surfaces configuration limits access to the required examination volume, and whether any alternate scanning angles can be used to achieve coverage in this area.

Relief Request 14A:

4. FPL letter dated February 20, 2006, states the objective of Relief Requests 14A and 15A is to resubmit the previously approved Relief Request 14 and 15 for Class 1 and 2 vessel inside radius, vessel welds, and piping welds that did not receive code-required volume. In comparing Relief Request 14 and Relief Request 14A, there are four components (29"-RCS-1305-3, 8"-SI-2309-22, 8"-SI-2309-24, and 6"-BDA-2301-8) that are listed in Relief Request 14 but not in Relief Request 14A. Please explain why the four components are not included in Relief Request 14A.

5. In Relief Request 14, component 3-SRGN-01-IR is listed under examination category B-D, item No. B3.120, which is applicable to the Pressurizer. In Relief Request 14A, component 3-SRGN-01-IR is listed as applicable to examination category B-D, item No. B3.140. Please explain this change in classification of component 3-RGN-01-IR.

6. Table 1 identifies the applicable code requirement for component Spray Nozzle-SP 1-IR as examination category B-D, item No. B3.140, which is applicable to steam generators. Please clarify whether this is a pressurizer spray nozzle or if it is applicable to steam generators.

7. Table 1 of Relief Request 14A indicates 66-percent coverage from the elbow side for component 31"-RCS-1302-10 was achieved. Relief Request 14 indicates 75-percent coverage from the elbow side for component 31"-RCS-1302-10 was achieved. Please explain the difference in coverage reported between the FPL August 8, 1996, letter and the February 20, 2006, letter.

8. Describe any flaws or relevant indications identified adjacent to the areas that could not be examined.

Relief Request 15A:

9. Describe any flaws or relevant indications identified adjacent to the areas that could not be examined.
