Nine Mile Point is conducting a dosimetry focus self assessment. Any and all information you can provide on the following effective dose equivalent external questions would be greatly appreciated. 1. Does your plant use all seven compartments per Regulatory Guide 8.40, Table 1 when using EDEX (i.e. every multipack has seven dosimeters)? Our procedures allow us to combine compartments. We have not combined compartments for any EDE packs due to the potential dose rate variance from one compartment to another. 2. If "No" to #1 and your site combines compartments, what locations do you group together? We would combine the thorax and abdomen and call it the chest compartment if we were to do it. 3. Has your site performed any calculations to determine the delta in total EDEX dose using all seven dosimeters versus the overall dose using combined compartments? If "Yes", would you be willing to share your results with me at [email protected]<mailto:[email protected]>? N/A Jeremy Bebb Staff Health Physicist Cooper Nuclear Station (402) 825-5026
