==Dear Sir:==

Entergy Nuclear Operations, Inc (Entergy) is submitting additional information to support NRC review of the alternate source term (AST) license amendment request (Reference 1) for Indian Point 3 (IP3). This letter provides additional information regarding the recently completed tracer gas testing and also supplements the information provided in Attachment 7 of Reference 2 regarding dose consequences in the Unit 2 control room for hypothetical accidents occurring at Unit 3, and vice versa.
The additional supporting information, provided in Attachment 1, does not alter the conclusions of the no significant hazards evaluations that support the AST license amendment request. If you
                                                                                                       - l)

NL-05-026 Docket 50-286 Attachment 1, Page 1 of 3 NRC QUESTION:
Please discuss the impact of postulated accidents occurring at 1P3, on control room doses at the IP2 and vice versa.
ENTERGY RESPONSE:
Supplementing our response provided in letter NL-05-020 dated 2/11/05, dose calculation results are provided below for control room doses at IP3 from accidents at IP2, and for control room doses at IP2 from accidents at IP3. In addition, atmospheric diffusion factors for IP2 release points to the IP3 control room are provided. The mode of operation of the IP3 control room HVAC is the mode proposed in our AST submittal of June 2, 2004 with 1500 CFM filtered makeup in the emergency mode.
As can be seen from the results below, all dose results are well below 5 REM TEDE. Thus, it may be concluded that the requirements of GDC 19 are satisfied for accidents occurring at either unit and the effects at the other unit's control room.

This is because the Unit 2 analysis does not credit switchover for an accident occurring at Unit 3, but it does credit a 60-second switchover for a SLB at Unit 2.

NL-05-026 Docket 50-286 Attachment 1, Page 3 of 3 NRC QUESTION:
The response to question 7c in Entergy letter NL-05-013, dated January 28, 2005 stated that tracer gas testing may identify the most significant sources of unfiltered inleakage. Are the X/Q values used in the AST analysis still appropriate based on inleakage source location that may have been identified during the recently completed testing?
ENTERGY RESPONSE:
The Tracer Gas Testing has been completed and the measured inleakage values were reported in Entergy Letter NL-05-020 dated February 11, 2005. Although the control room inleakage was very low in the emergency mode (less than 100 cfm), the test did indicate the major source of the leakage was associated with the pressurization fans and the air filtration unit located inside the HVAC equipment room on elevation 15 ft. Since the inlet for ventilation for this room is co-located with the inlet for the HVAC equipment for the control room, the XIQs would be identical.
