E-1 TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT (BFN)

UNITS 1, 2, AND 3 LICENSE RENEWAL APPLICATION (LRA)

RESPONSE TO NRC REQUEST FOR ADDITIONAL INFORMATION (RAI) ON FOLLOW-UP TO RAI 2.3.3.21-4b By letter dated December 31, 2003, TVA submitted, for NRC review, an application pursuant to 10 CFR 54, to renew the operating licenses for the Browns Ferry Nuclear Plant, Units 1, 2, and 3. As part of its review of TVAs LRA, the NRC staff, through an informal request on May 4, 2005, identified additional information needed for follow-up to RAI 2.3.3.21-4b. This enclosure contains the specific NRC request for additional information and the corresponding TVA response.

NRC Follow-up to RAI 2.3.3.21-4b With regard to RAI 2.3.3.21-4b, the applicant stated that flow indicators are not contained as a component type in LRA Table 2.3.3.21. Flow indicators were excluded from an AMR based on guidance provided in NEI 95-10 Appendix B.

Based on its review, the staff is not able to find the applicant's response to RAI 2.3.3.21-4 acceptable. The applicant follows the guidance in NEI 95-10 which lists flow indicators as active components. However, the flow indicators in question are in-line indicators. The indicator portion of the component is an active component, but the piping portion of the indicator through which flow goes provides a pressure boundary function. Therefore, this portion of the component should be within scope and subject to an AMR. Therefore, the staff is not able to determine that the integrity of the reactor water cleanup system will be ensured.

TVA Response to follow up to RAI 2.3.3.21-4b The pressure boundary portion of the flow indicators are in scope and are evaluated as fittings in the Control Rod Drive System (85). License Renewal Drawings 1-47E810-1-LR, 2-47E810-1-LR, and 3-47E810-1-LR were revised to show FI-75 and FI-77 in blue for 54.4(a)(2). The pressure retaining portion of the flow indicators are stainless steel with an internal environment of treated water with an external environment of inside air and are already contained in Table 3.3.2.29 of the LRA.

E-2 All license renewal boundary drawings were reviewed for in-line flow indicators which provide a pressure boundary function. This review identified that the following system drawings also contain flow indicators that form a pressure boundary, and the drawings were updated as listed below:

System 43 changes Drawing 1-47E610-43-1-LR was revised to show FI-11,

-12A, and -12B and FIS-13A and -13B in blue for 54.4(a)(2).

Drawing 2-47E610-43-1-LR was revised to show FI-10,

-11, -12A, -12B, FIC-10A, -10B, -10C, -11A, -11B,

-11C, -12A, -12B, and FIS-13A and -13B in blue for 54.4(a)(2).

Drawing 3-47E610-43-1-LR was revised to show FIS-13A and -13B in blue for 54.4(a)(2).

Drawing 3-47E610-43-6-LR was revised to show FI-10,

-11, -12A, -12B and FIC-11A, -11B, -11C, -12AA, -12AB,

-12BA, and -12BB in blue for 54.4(a)(2).

No changes are required to LRA Table 3.3.2.14 since fittings contain the material/environment combinations for the in-line FIs, FICs and FISs which provide a pressure boundary function.

System 68 changes Drawing 1-47E817-1-LR was revised to show FIS-55, -62,

-68, and -74 in blue for 54.4(a)(2).

Drawing 2-47E817-1-LR was revised to show FIS-55, -62,

-68, and -74 in blue for 54.4(a)(2).

Drawing 3-47E817-1-LR was revised to show FIS-55, -62,

-68, and -74 in blue for 54.4(a)(2).

Drawing 1-47E822-1-LR was revised to show FIS-53 and

-66 in red for 54.4(a)(1).

Drawing 2-47E822-1-LR was revised to show FIS-53 and

-66 in red for 54.4(a)(1).

No changes are required to drawing 3-47E822-1-LR since FIS-53 and -66 were already red for 54.4(a)(1).

E-3 No changes are required to LRA Table 3.1.2.4 since fittings contain the material/environment combinations for the in-line FISs which provide a pressure boundary function.

System 69 changes Drawings 1-47E837-1-LR was revised to show FI-38,

-55, and -81 in blue for 54.4(a)(2).

Drawings 2-47E837-1-LR was revised to show FI-38,

-55, and -81 in blue for 54.4(a)(2).

Drawings 3-47E837-1-LR was revised to show FI-38,

-55, and -81 in blue for 54.4(a)(2).

No changes are required to LRA Table 3.3.2.21 since fittings contain the material/environment combinations for the in-line FIs which provide a pressure boundary function.

System 74 changes Drawing 1-47E811-1-LR was revised to show FIS-4, -15,

-27, and -38 in blue for 54.4(a)(2).

Drawing 2-47E811-1-LR was revised to show FIS-4, -15,

-27, and -38 in blue for 54.4(a)(2).

Drawing 3-47E811-1-LR was revised to show FIS-4, -15,

-27, and -38 in blue for 54.4(a)(2).

Add the following Material to page 3.2-8: Glass Add the information from the next page to Table 3.2.2.4 on page 3.2-50.

No other changes are required to LRA Table 3.1.2.4 since fittings contain the other material/environment combinations for the in-line FISs which provide a pressure boundary function.
