u.s. Nuclear Regulatory Commission February 18, 2009 Page 2 of 3 In Reference 2, AmerGen provided additional, minor changes affecting TMI-1 TS 6.6.1.b and TS 6.17.1.2.
Subsequently, per teleconference on February 2,2009 with Exelon Generation Company, LLC (Exelon), the NRC indicated that Administrative Letter (AL) 95-06, "Relocation of Technical Specification Administrative Controls Related to Quality Assurance," dated December 12,1995, guidelines require TSs to be relocated verbatim to the Exelon Quality Assurance Topical Report (QATR) as an acceptable method for removing the applicable administrative controls from the OCNGS and TMI-1 TSs. Accordingly, Exelon will relocate verbatim the OCNGS and TMI-1 TS 6.5, "Review and Audit," requirements to the Exelon QATR within 60 days from the issuance of the approved amendments and prior to the implementation of the deletion of the TS 6.5 requirements from the OCNGS and TMI-1 TSs.
Exelon has concluded that the supplemental proposed changes do require a change to the original no significant hazards consideration (NSHC) evaluation submitted in the Reference 1 license amendment request. A revised NSHC evaluation is provided in the Attachment to this letter.
Pursuant to 10 CFR 50.91 (b)(1), a copy of this supplement is being provided to the designated officials of the State of New Jersey and the Commonwealth of Pennsylvania, as well as the chief executives of the township and county in which the facilities are located.
No new regulatory commitments are established by this submittal.

5.0 REGULATORY ANALYSIS
5.1 No Significant Hazards Consideration Exelon Generation Company, LLC (Exelon) has evaluated whether or not a significant hazards consideration is involved with the proposed amendments by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of Amendment," as discussed below:
- 1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No.
No physical changes to the facilities, Oyster Creek Nuclear Generating Station (OCNGS) and Three Mile Island Nuclear Station, Unit 1 (TMI-1), will occur as a result of the proposed amendment. The proposed changes will not alter the physical design or operational procedures associated with any plant structure, system, or component.
The proposed changes include the relocation of several administrative requirements from the Technical Specifications (TSs) to the Exelon Quality Assurance Topical Report (QATR) and are administrative in nature. The TS requirements involve Technical Review and Control and Audits. In accordance with the guidance provided in NRC Administrative Letter 95-06, "Relocation of Technical Specification Administrative Controls Related to Quality Assurance," the proposed changes are an acceptable method for removing TS quality assurance requirements.
The additional proposed changes (OCNGS: correcting typographical errors and removing a surveillance requirement for the condenser vacuum pump isolation trip system; TMI: correcting typographical errors, providing improved TS Figure legibility, updating the description of the installed spent fuel pool storage locations and correcting an error in the labeling of outfalls on the TMI site drawing) are administrative in nature and have no affect on plant operation. The changes do not reduce the duties and responsibilities of the organizations performing the technical review, independent safety review and audit functions essential to ensuring the safe operation of the plant.
Therefore, the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No.
The proposed changes are administrative in nature. The proposed changes do not alter the physical design, safety limits, or safety analysis assumptions associated with the operation of the plant. Accordingly, the changes do not introduce any new accident initiators, nor do they reduce or adversely affect the capabilities of any plant structure, system, or component to perform their safety function.
Attachment Revised No Significant Hazards Consideration for TSCR 330 & 336 Page 2 of2 Therefore, the proposed changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. Does the proposed amendment involve a significant reduction in a margin of safety?
Response: No.
The proposed changes to relocate TS 6.5 requirements to the QATR conform to NRC regulatory guidance regarding the content of plant TSs. The guidance is presented in Administrative Letter 95-06, NUREG-1430 and NUREG-1433. The relocation of these administrative requirements will not reduce the quality assurance commitments as accepted by the NRC, nor reduce administrative controls essential to the safe operation of the plant. Future changes to these administrative requirements will be performed in accordance with NRC regulation 10 CFR 50.54(a), consistent with the guidance identified above. Accordingly, the relocation of the TS requirements to the QATR results in an equivalent level of regulatory control.
The additional proposed changes are administrative changes that do not involve a margin of safety.
Therefore, the proposed changes do not involve a significant reduction in a margin of safety.
Based on the above, Exelon concludes that the proposed amendment presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified.
