Need for clarification on your May 20, 2011 submittal on Chapter 11
- Bill, As a follow-up to our discussion with you and your staff on June 7, 2011, below is our need for clarification due to your response dated May 20, 2011. Please review and let me know if you need any clarification on our concerns. If not, I will begin processing these as formal RAIs. Thanks.
- 1. Even with the added text in this section, it is still unclear what effluent pathway is indicated by the term F - condensate demineralizer flow (and subsequently the related F/H and F/H/D terms) as used in the foot note to Table 11.2-5. As written, it seems to indicate the entire condensate flow through the condensate demineralizer (e.g., 55% of the entire condensate flow) when in service. TVA needs to clarify that the effluent path and plant operational mode of interest here is:
- a. Waste condensate that is discharged from the condensate system during operations with primary to secondary leakage sufficient to reroute the SGBD to the condensate system [If this is the case, provide the flow rate and verify that the condensate is released from the condensate demineralizer system downstream of the demineralizer, before it is recombined with the 45% of the condensate that bypasses the demineralizers]; or
- b. Liquid effluent resulting from the regeneration of the condensate demineralizers during operations with primary to secondary leakage sufficient to reroute the SGBD to the condensate system [in which case explain how this is processed through the condensate demineralizers before being processed by the mobile demineralizer]; or
- c. None of the above [explain].
- 2. The second issue is that it is not clear how the design basis source term (based on 1% failed fuel and the maximum SGBD activity) listed in column 5 of Table 11.2-5d is derived. Verify that the values listed in this column is the result of adding the SGBD value in column 3 to the product of columns 2 and 4 for each isotope. If this is incorrect explain.
