Unacceptable with Opportunity to Supplement: LAR to Revise TS to Eliminate Main Steam Line Radiation Monitor Reactor Trip and Primary Containment Isolation System Group 1 Isolation Functions Mr. Hass, By letter dated August 24, 2017, DTE submitted a license amendment request for Fermi 2 which would eliminate the main steam line radiation monitor (MSLRM) functions for initiating: 1) a reactor protection system (RPS) automatic reactor trip and 2) the associated (Group 1) primary containment isolation system (PCIS) automatic closure of the main steam isolation valves (MSIVs) and main steam line (MSL) drain valves. As we discussed on the phone today, NRC has reviewed your application and concluded that the information below is necessary to begin its detailed technical review. A conference call will be scheduled with NRC and your staff to discuss the needed information in detail. Please let me know if Friday, September 29, 2017 at 10 a.m. EST will work for your staff.

Input to the ARCON96 Main Control Room (MCR) Atmospheric Dispersion Analyses The atmospheric dispersion factors for accident analysis from the condenser and steam-jet air ejector included in Table 1 of Enclosure 1 to the LAR submittal represent new release points that were not considered when license amendment 160 was issued in September 28, 2004, Selective Implementation of Alternative Radiological Source Term Methodology (ADAMS accession ML042430179). Therefore, the following information is needed to review the new set of atmospheric dispersion factors:

a. The hourly meteorological dataset (in electronic format) used to derive the updated /Q values in the format specified in Appendix A to Revision 1 to RG 1.23.

b. The ARCON96 input and output files used for all source-receptor pairs.

c. A graphic showing the relative locations of the sources and MCR receptors.

d. A table identifying the distance and direction of the source-receptor pairs, as well as the heights of the MCR intakes and release points.
