Υ Υ 7Most ESP applicants have chosen a plant parameter envelope approach, which means no reactor design has been selected. In these situations, it is not possible to calculate χ/Q values for the CR, TSC, and in-leakage locations because the plant configuration is unknown. 8The DC does not need routine release χ/Q and D/Q site parameter values to compare against ESP and COL site characteristic values. A COL applicant referencing a DC is expected to utilize its site-specific χ/Q and D/Q site parameter values to perform site- specific gaseous pathway dose analyses following the guidance provided in Regulatory Guides 1.109 and 1.111 and compare the doses to the numerical design objectives of 10 CFR Part 50, Appendix I and demonstrate compliance with the requirements of 10 CFR 20.1302 and 40 CFR Part 190. 9 The UHS is typically not within the scope of the DC, however, SRP Section 9.2.5 includes guidance for reviewing a UHS in the DC. 2.0-16 Revision 1 – October 2016 SRP Site Characteristic DC Site Site Characteristic/Site Parameter Section ESP(1) COL Parameter Travel Time for Groundwater Flow
