In Reference 2, the NRC requested additional information in order to complete its review of the LAR.The questions are restated below along with Exelon's response.Section 4.0,"Technical Analysis, II of the LAR describes changes to several TS pages where relocation references are proposed to be changed from the Updated Final Safety AnalysisReport(UFSAR) to the Technical Requirements Manual (TRM).Item 4 in LAR Section 4.0, states that the LGS TRM is incorporated into the LGS UFSAR"by reference." The LGS UFSAR, Section 1.6, titled"Material Incorporated by Reference/General Reference" does not list the TRM as a document incorporated by reference.

Furthermore, the discussion of the TRM in UFSAR, Section 13.5.3, does not state that the TRM is"incorporated by reference." Nuclear Energy Institute (NEI)98-03,"Guidelines for Updating Final Safety Analysis Reports," Revision 1, dated June 1999, provides instructions on the proper way to incorporate material by reference into the UFSAR.U.S.NRC Regulatory Guide (RG)1.181, Revision 0, dated September 1999, titled"Content of the Updated Final Safety Analysis Report in Accordance with[Title10 of the Code of Federal Regulations]

10 CFR 50.71 (e)," endorses NEI 98-03, Revision 1.RG 1.181, Revision 0, is in turn endorsed by the LGS UFSAR in Section 1.8.NEI 98-03 discusses the relationship of the TRM to the UFSAR and describes two options for TRM control.Under option one of NEI 98-03, the TRM is"incorporated by reference" into the UFSAR.With option two, the TRM is treated in a manner consistent with procedures fully or partially described in the UFSAR.Option one requires an explicit UFSAR statement of"incorporation by reference." It also requires the TRM to be subject to the update/reporting requirements of 10 CFR 50.71 (e).With option two, the important consideration is the treatment of the TRM such that its contents are considered aslevel information when evaluating changes under 10 CFR 50.59.LGS UFSAR 13.5.3 refers to control of the TRM under 10 CFR 50.59, but does not clearly specify that information contained in the TRM is UFSAR-Ievel material.Based on this discussion please answer the following:

1.)Is it your intent to consider theTRM"incorporated by reference" into the UFSAR in accordance with the process described in NEI 98-03, or do you plan to control the TRM in accordance with option two described above?If you plan to use option two will you treat the TRM consistent with procedures fully or partially described in the Response to Request for Additional Information License Amendment Request Proposed Administrative Changes to Technical Specifications Docket Nos.50-352 and 50-353 Attachment 1 Page 2 of 3 UFSAR?Also, if option two is desired, do you plan to update your UFSAR Section 13.5.3 to clearly specify the treatment of TRM material as"described in the final safety analysis report, as updated" under 10 CFR 50.59?Response Exelon acknowledges that the LGS TRM isnotexplicitly lIincorporated by reference ll in the LGS UFSAR in accordance with the guidance provided in NEI 98-03, Revision 1.LGS UFSAR Section 13.5.3 provides a general reference to the TRM by providing a description of the TRM, its contents, its purpose, and the controls under which changes to the TRM are evaluated, reviewed, and approved.UFSAR Section 13.5.3 specifically states that individual sections of the TRM contain relocated licensing commitments which are subject to the provisions of 10 CFR 50.59, and are controlled in accordance with the applicable established procedure process.Since its inception in the mid-1990*s, the LGS TRM, in accordance with the guidance provided in NEI03, Revision 1, as endorsed by NRC RG 1.181, has been treated and controlled as a procedure described in the UFSAR, and any changes to the TRM have been evaluated under the requirements of 10 CFR 50.59.Coincident with the issuance of this request for additional information, Amendment Nos.191 and 152 for LGS, Units 1 and 2, respectively, were issued by letter dated May 29, 2008 (Reference 3).These amendments involved deleting the operability and surveillance requirements for the drywell air temperature and suppression chamber air temperature post-accident monitoring instrumentation from TS and relocating the requirements to the LGS TRM.To ensure that the information contained within the TRM is treated at the same level as information contained within the UFSAR for 10 CFR 50.59 purposes, these amendments required updating the LGS UFSAR to include, but not limited to, a statement that the TRM is treated in a manner consistent with procedures fully or partially described in the UFSAR.For the purposes of 10 CFR 50.59, information presented in the TRM is considered to be information described in the UFSAR, and therefore, is to be treated at the same level as information presented in the UFSAR.Therefore, LGS UFSAR Section 13.5.3 will be updated as part of the implementation of these amendments as required by Reference 3.2.)LGS Unit 1 TS page 3/41-12 proposes to delete paragraph 4.1.3.6(d), but does not propose to move the"and" from 4.1.3.6(c) to 4.1.3.6(b).

Please consider submitting a corrected TS page to address this grammatical issue.Response A corrected LGS, Unit 1, TS page 3/4 1-12 is provided in Attachment 2.All other TS markup pages provided in the Reference 1 submittal remain unchanged.
