Subject: Re: MV Liquid

‐ immersed LCC and NIA Results

Chris,

After doing so me preliminary study of the information you sent, we have 4 questions as follows where

we would appreciate some additional information:

1. Overall

‐ So that we can more effectively analyze this new information,

could you please provide a brief summary of significant changes from the

9/09/2011 results?

2. Designs Used

‐ Can we assume that the designs defined in the 8/23 and

9/08/2011 Engineering Data files are the same designs used for this

analyses, excluding the ZDMH core designs?

3. Chart 16

‐ The label above the top table reads "Summary Results by TSL for

Liquid

‐ immersed Transformers". We believe this label should rea d "Summary

Results by EL for Liquid

‐ immersed Transformers". Are we correct?

4. Chart 18

‐ This chart describes 6 draft TSLs. However, the chart then shows 7 TSLs. While TSL6 and

TSL7 appear to be the same, is there significance to this additional TSL?We would appreciate a quick response such that we can understand this information prior to our

upcoming meeting.

Thanks for your help.
