In the Matter of ENTERGY NUCLEAR OPERATIONS, INC. (Vermont Yankee Nuclear Power Station) Docket No. 50-271-LR; ASLBP No. 06-849-03-LR

Dear Administrative Judges:

It has come to the Staffs attention that testimony provided in Affidavit of Kenneth C.

Chang Concerning NEC Contentions 2A & 2B (Metal Fatigue) (Staff Exh. 2) contained errors.

Enclosed are Affidavit of Kenneth C. Chang dated May 21, 2008 and replacement pages for Affidavit of Kenneth C. Chang Concerning NEC Contentions 2A & 2B.

It has also come to the Staffs attention that in Staff Exh. 1, the last page of Section 4.3 (page 4-43) was missing. Please find that page enclosed.

Sincerely,

/RA/ Lloyd B. Subin Counsel for NRC Staff

In the Matter of ) ) ENTERGY NUCLEAR VERMONT YANKEE, LLC ) Docket No. 50-271-LR AND ENTERGY NUCLEAR OPERATIONS, INC. ) ) (Vermont Yankee Nuclear Power Station) )

AFFIDAVIT OF KENNETH C. CHANG I, Kenneth C. Chang, do hereby declare under penalty of perjury as follows: 1. In A.4 on page 5, lines 11-12, of Affidavit of Kenneth C. Chang Concerning NEC Contentions 2A & 2B (Metal Fatigue) (Staff Exh. 2) I in inadvertently wrote that "the FW nozzle is Vermont Yankee's most FAC-susceptible nozzle." I intended to write that "the FW nozzle is Vermont Yankee's most limiting (i.e. nozzle with highest CUFen)." 2. Therefore, in A.4 on page 5 in line 12, the words "FAC-susceptible" should be stricken and replaced with the words "most limiting (i.e. nozzle with the highest CUFen)."

3. The sentence in A.11 on page 10 lines 1-7 of Affidavit of Kenneth C. Chang Concerning NEC Contentions 2A &2B (Metal Fatigue) (Staff Exh. 2) is unclear and must be revised.

4. The existing sentence should be replaced with the following: Error analysis is not necessary because conservatism is built into the design fatigue curves for carbon steel/stainless steel in the light water environment. As stated in NUREG/CR-6583 and NUREG/CG-5704, these design curves have been adjusted for uncertainties that are associated with material and loading conditions.

4-43application using the specific software could underestimate the CUF, and therefore, cannot be enthe analysis of record. However, the updated analysis, whether using the maximum F or enappropriate Fs, yields CUFs lower than the Code allowable. The staff concludes that thisupdated analysis are the analysis of record for the FW nozzle. Based on the above discussion, the staff concludes that similar analysis should be performed for the CS and the RR outlet nozzles and that these analyses will be documented as the analyses of record for these two nozzles. On this basis, the staff finds that although the applicant has used a 2-dimensional axisymmetricmodel to handle thermal transient and pressure, it did consider the six stress components and use them to develop three principle stresses and the stress intensities. Therefore, the staff finds that for the updated analysis of the FW nozzle, the stress intensities and the CUFs are calculated in accordance with ASME Code requirements. The staff concluded that the updated FW analysis consistent with the rules of the ASME Code Section III yields lower EAF CUF values for the FW nozzle. In the letter dated February 21, 2008, the applicant stated that it considers the updated EAF analysis, submitted in the January 30, 2008 letter, as the analysis of record for the FW nozzle. The staffs concern expressed in RAI 4.3.3-2 is resolved. However, a license condition for performing the ASME Code analyses for the CS and the RR outlet nozzles will remain in effect until the applicant has completed and submitted those final analyses for NRC review and approval no later than two years prior to entering the PEO.4.3.3.3 UFSAR SupplementThe applicant provided a UFSAR Supplement summary description of its TLAA evaluation ofeffects of reactor water environment on fatigue life in LRA Section A.2.2.2.3. The staff reviewed the applicants Commitment No. 27 and concludes that implementation of thiscommitment prior to period of extended operation will address environmentally assisted fatigue for the seven components which have not been addressed.On the basis of its review of the UFSAR Supplement, the staff concludes that the summarydescription of the applicants actions to address effects of reactor water environment on fatigue life is adequate.4.3.3.4 ConclusionOn the basis of its review, and Commitment No. 27 as discussed above, the staff finds that theapplicant has demonstrated that, as required by 10 CFR 54.21(c)(1)(iii), the effects of aging on the intended function(s) will be adequately managed for the period of extended operation. The staff also concludes that the UFSAR Supplement contains an appropriate summary description of the TLAA evaluation, as required by 10 CFR 54.21(d).
