BROWNS FERRY NUCLEAR PLANT (BFN) - UNIT 3 - SUPPLEMENTAL RESPONSE TO GENERIC LETTER (GL) 88-01, NRC POSITION ON INTERGRANULAR STRESS CORROSION CRACKING (IGSCC) IN BWR AUSTENITIC STAINLESS STEEL PIPING

Reference:

Letter from TVA to URC dated August 1, 1988,

• BFN - Response to Generic Letter 88-01, NRC Position on IGSCC in BWR Austenitic Stainless Steel Piping, dated January 25, 1988" As documented in the reference, TVA is providing the Unit 3 Supplemental response to GL 88-01, (Enclosure) for NRC review and issuance of a Safety Evaluation Report to support Unit 3 restart.

The program to mitigate IGSCC on Unit 3 is nenring completion. ' Inspection I

using state-of-the-art nondestructive examination equipment, weld crown reduction, qualified examinera, and qualified techn3 Ties has been performed.

Repair of IGSCC indications is being pedarmed by using' full structural weld overlays or replecoment piping wi.th IGSCC resistant raaterial. Where practical, stress improvement'of susceptible piping and replacement piping has been performed.

A reduction in the number of welds was achieved by using designs which employ integral bends and branches in replacement piping where possible.

If you have any questions, please telephone G.'D. Pierce, Interim Manager of site Licensing, at (205) 729-7566.

Sincerely,

' ENCLOSURE RESPONSE TO' GENERIC LETTER 88-01:-

REPORT OF INSPECTION,' REPAIR, AND MITIG ATION PERFORMED ON--

BROWNS FERRY UNIT 3 IGSCC SUSCEPTIllLE PIPING Introduction q

Nondestructive examination, repair, stress improvement and pipe replacement with corrosion resistant materials have been implemented on Browns Ferry Unit 3. These activities have been performed to reduce the potential for Intergranular Stress Corrosion Cracking (IGSCC).

and are consistent with the NRC positions provided in Generic Letter (GL) 88 01 and prevailing BWR industry practice.

1.0 PLANS REGARDING LONG-TERM MITIGATION OF IGSCC-The measures taken on BFN Unit 3 to mitigate IGSCO are nearing completion and are I

summarized below:

Inspection using state-of-the-art nondestructive examination equipment, qualified examiners, and qualified techniques has been performed. -Weld crown reduction has -

also been employed to enhance the quality.of the examination. Results of the inspections performed are summarized in Table 1.

l Repair of IGSCC indications is bang performed by using full structural weld overlays or replacement piping. Weld l overlay material and replacement pipingt materials utilized are resistant to IGSCC as defined in the GL 88-01. SVelds being repaired by weld overhy application are described in Table 1. iWhen installation'is'-

complete, BFN Unit 3 piping will have a total of nine weld overlays (To date,j sever, weld overlays have been applied and two are in.the process of being installed.

Replacement weldments made with resistant material are identified in Table li-Where practical, stress improvement of susceptible piping and replacement pipingj has been performed. Both mechanical and induction heating methods have been :

~ '

employed. Stress improvement of welds with the applied treatment method is.

described in Table 1.

A reduction in the number welds.was achieved by using designs which employ-integral bends and branches in replacement piping where possible. - Replaced piping on Unit 3 has resulted in a net reduction of the number of welds.

i Reactor recirculation piping was replaced downstream of the 28" pump dischargo?

Reactor water c!nrap piping was replaced both inside and outside containment.

This replacement included the penetration process piping and, as such, climinated the ur6nspec:able weld located inside the penetration. The rephccment material utilire.d is resistant to IGSCC, 316NG stainless steel was used for all piping operating above 200"F.

Jct pump instrumentation nonle safe ends and seal assemblics were replaced to remove cracking ne averlays that were not suitable for long term operation. The replaen. tent assemblict were of rm improved design and were fabricated from IGSCC redswat materlah.

Details concemirr the replacement welds is inchided in Table 1.

The llFN ISI program plan has been ecnfignted to ensure this objective.

2.1.0 ISLl> lam.fptCydn1 Refueling 10ntacc To address the requirement.s for Anspection schedules and expansions plans,'the 11FN susceptible weldr.nenh have been categorized according to NUREG 0313 Revision 2, section 5, Table 1. This categotization is listed in Table 1. The ISI plans for the cycle 6 refueling outage are to inspect the welds a required by the 13FN Technical Specification 1.MM.6.

3.0 DJ',MQhSJE ATION OF CQEQ1(MANCE TO Tl]E ISI REOUIREMENTS -

OlL & M al OL 88 01 requests a change to the technical specification section on ISI to state that the ISI progrmn for piping covered by the scope of the GL 88-01 will be in conformance with the stafi' positions therein expressed. Technical specification conformance with this requirement-has been p:eviously submitted to NRC and upproved as TS-262 issued on May 19, 1989, 3

L

' 4.0 IEQlMCAL_SI'ECIHCATION ON CONFOl{hlANCE TO STAFF POSITIONS ON_ LEAK DETECT 10N Technical specincation conformance with this requirement has been previously submitted to NitC and approved as TS-222 issued August 26,,982. No additional actions are required in this matter, llFN will monitor leakage according to the technical specincations.

5.d J'LANS TO_ NOTID' NitC OF FLAWS in this report, as in the past, N1(C has been notined of the inspection results, flaw evaluations and repair mitigation measures associated with the llFN units through a comprehensive report submitted before plant startup. This report covers the Unit 3 activities.

After the IGSCC mitigation work scopes have been fully implemented, reports will be made only in the event of the discovery of new flaws, or a change found in the condition of flaws previously detected, in these instances, a fuil report of the flaw evaluation and the strategy and technical justification for repair or continued operation will be submitted.
