" Response to NRC Findings on GIST: GIST Heat Loss, and TRACG Application to SBWR, dated November 18,1993.
Enclosed is the non-proprietary version of the subject charts requested by Reference 1 resulting from your review of our Reference 2 transmittal of the corresponding proprietary presentation charts. In preparing these non-proprietary charts, we reviewed the Reference 2 charts for those that were clearly not proprietary. Further, we reviewed all the charts again and identified several additional charts that could and have been reclassified as non-proprietary.
Sincerely,7

GIST Heat Loss Heat Loss does not have a Significant Impact on GIST
. Heat Loss given by conduction through insulation, free convection heat transfer
- pro, and ambient temperature.
