TVA letter to the NRC dated October 21, 2010, "Watts Bar Nuclear Plant (WBN) - Unit 2 - Final Safety Analysis Report (FSAR) Section 2.3" This letter transmits WBN Unit 2 FSAR Amendment 101 (A101), which reflects changes made since the issuance of Amendment 100 on September 1, 2010 (Reference 1). contains a summary listing of FSAR sections and corresponding Unit 2 change package numbers associated with the A101 FSAR changes. Most of these changes were the result of resolutions to Requests for Additional Information. Section 2.3 was provided in advance via Reference 2. However, some additional changes to this section were discussed in a telecon with the NRC on October 28, 2010. These changes have been incorporated and are being provided in FSAR A101.

FSAR A101 is contained on the enclosed Optical Storage Media (OSM #1) (Attachment 1). The FSAR contains security-related information identified by the designation "Security-Related Information - Withhold Under 10 CFR 2.390.". TVA hereby requests this information be withheld from public disclosure in accordance with the provisions of 10 CFR 2.390. A redacted version of the FSAR is contained on OSM #2 (Attachment 2), which is suitable for public disclosure. contains a listing of the FSAR pages that have been redacted. Enclosure 3 lists the files and file sizes on the security-related OSM (OSM #1), and Enclosure 4 lists the files and file sizes on the publicly available OSM (OSM #2). There are no new commitments contained in this letter.

Section 11.2.6.5 Table 11.2-5c Table 11.2-5d

1.

Replace existing text contained in Section 11.2.6.5 with the following:

"The potential releases have been evaluated as indicated in the above sections. The expected liquid releases from Watts Bar are well below the limit of 5 Curies (Ci) per year as prescribed in 10 CFR 50, Appendix I as shown by the values given in column 4 and 5 of Table 11.2-5. Column 6 (no CD processing) indicates a yearly release of 30.03 Ci with no Condensate Demineralizer (CD) processing of waste and no limitations on steam generator blow down concentrations. This operational mode is not normally used since long term use results in exceeding the 5 Ci/yr limit in 10 CFR 50, Appendix I. Column 7 of Table 11.2-5 indicates that the total release, including untreated steam generator blow.down, is significantly below the 10 CFR 50, Appendix I limit of 5 Ci/yr if the steam generator blow down concentration is restricted to the Lower Limit of Detection (LLD) of 5E-7 uCi/cc gross gamma during the release and no other Condensate Demineralizer waste is processed during the release. However, column 7 does include other releases from waste holdup tanks which are treated using the Mobile Demineralizers. Column 8 of Table 11.2-5 indicates steam generator blow down can be released untreated and remain within the 10 CFR 50, Appendix I limit of 5 Ci/yr if the Steam Generator Blow down concentration is restricted to a maximum concentration of 3.65E-5 uCi/cc gross gamma during the release and no other Condensate Demineralizer waste is processed during the release.

However, column 8 does include other releases from waste holdup tanks which are treated using the Mobile Demineralizers.

Tables 11.2-5a, 11.2-5b, 11.2-5c, and 11.2-5d describe liquid releases for 1% failed fuel for both treated and untreated waste relative to the requirements of 10 CFR 20.1302(b). The sum over all isotopes of the concentrations/ECL (C/ECL) value from the Table 11.2-5a is greater than unity for the case where all isotopes are at design values and the released liquid is not processed by the Mobile Demineralizers. This mode of operation is not normally used since the C/ECL value exceeds the requirements of 10 CFR 20.1302(b).

The bulk of the release is due to the untreated condensate resin regeneration waste. In order to prevent exceeding the 10 CFR 20.1302(b) limits, the condensate regeneration waste is rerouted through the Mobile Demineralizers if the long term releases from the condensate regeneration waste is greater than the 10 CFR 20 concentration limits. With Mobile Demineralizer processing of condensate regeneration waste, the release concentrations are shown in Table 11.2-5b and are less than the limits specified in 10 CFR 20.1302(b). Table 11.2-5c shows releases remain within the 10CFR 20 limits if the steam generator blow down concentration is restricted to the Lower Limit of Detection (LLD) of 5E-7 uCi/cc gross gamma during the release and no other Condensate Demineralizer waste is processed during the release. However, these releases do include other releases from waste holdup tanks which are treated using the Mobile Demineralizers.

Table 11.2-5d shows releases remain within the 10CFR 20 limits if the steam generator blow down concentration is restricted to a maximum concentration of 3.65E-5 uCi/cc gross gamma during the release and no other Condensate Demineralizer waste is processed during the release. However, these releases do include other releases from waste holdup tanks which are treated using the Mobile Demineralizers."
