e l ATTACHMENT C l SIGNIFICANT HAZARDS CONSIDERATION This is a proposed change to Technical Specification 3/4.3.7.2, " Seismic Monitoring j instrumentation", Table 3.3.7.2-1, " Seismic Monitoring Instrumentation", Table 4.3.7.2- l 1, " Seismic Monitoring Instrumentation Surveillance Requirements", and Bases Section j 3/4 3.7.2," Seismic Monitoring Instrumentation". Comed proposes to relocate these 1 Technical Specifications requirements to licensee-controlled documents as discussed ! in Generic Letter 95-10, Relocation of Selected Technical Specifications Requirements ; Related to Instrumentation. The requirements for seismic monitoring instrumentation, t including a list of the components, will be included in the UFSAR and will be added to l the Administrative Technical Requirements. This change is required as a result of a Modification which replaces existing seismic ) monitoring instrumentation in Panel OPA11J with new instrumentation which are not l "like-for-like" replacements. These instrument replacements will directly impact the contents of Tables 3.3.7.2-1 and 4.3.7.2-1, which contain descriptions of the l instruments. Comed has evaluated the proposed Technical Specification Amendment and determined that it does not represent a significant hazards consideration. Based on , the criteria for defining a significant hazards consideration established in 10 CFR 50.92, operation of LaSalle County Station Units 1 and 2 in accordance with the proposed amendment will not:
- 1) Involve a significant increase in the probability or consequences of an accident previously evaluated because:
The function of the seismic monitoring instrumentation is to monitor seismic activity above the Operating-Basis Earthquake (OBE) threshold, and to record observed seismic data for comparison to design basis response spectra. The seismic monitoring instrumentation does not provide any function to mitigate an accident or the consequences of an accident. The replacement seismic monitoring instrumentation will remain in place. The proposed Amendment is not a result of any changes to system function, alarm setpoints, or main control room annunciators. Rather, the Technical Specification requirements (as revised for the replacement instrumentation) are being relocated to licensee-contro!'ed documents in accordance with NRC Generic Letter 95-10. l The proposed change relocates requirements and surveillances for structures, systems, components or variables that do not meet the criteria for inclusion in Technical Specifications as identified in the Application of Selection Criteria to C-1

! The replacement seismic monitoring instrumentation will have no impact on j margin of safety. The intended function of the seismic monitoring instrumentation, i.e. to record observed seismic data for analysis to determine ;

'_ modification. The Technical Specification requirements (as revised for the 1 replacement instrumentation) are being relocated to licensee-controlled documents in accordance with NRC Generic Letter 95-10.
l I 4 The proposed change will not reduce a margin of safety because it has no
- impact on any safety analysis assumptions. In addition, the relocated l requirements and surveillances for the affected structure, system, component or variable continue to meet the same requirements as the existing Technical {
i l Specifications. However, the LCO requirement specified in Section 3.3.7.2.a (to j prepare and submit a Special Report to the NRC within 10 days of the seismic ] monitoring instrumentation being inoperable for more than 30 days) will not be ; i included in the ATR since the Technical Specification Special Report i requirements are only applicable to the LCOs. Since any future changes to 7 these requirements or the surveillance procedures will be evaluated per the ! i requirements of 10 CFR 50.59, no reduction in a margin of safety will be i j permitted. ; 4 f , The existing requirement for NRC review and approval of revisions, in ! accordance with 10 CFR 50.92, to these details proposed for relocation does ! not have a specific margin of safety upon which to evaluate. However, since ) } the proposed change is consistent with the BWR Standard Technical ! l Specification, NUREG-1434, Rev.1 approved by the NRC Staff, revising the ! 4 Technical Specifications to reflect the approved level of detail ensures no : l significant reduction in the margin of safety. i i ' Guidance has been provided in " Final Procedures and Standards on No Significant i Hazards Considerations," Final Rule, 51 FR 7744, for the application of standards to 1 license change requests for determination of the existence of significant hazards considerations. This document provides examples of amendments which are and are i not considered likely to involve significant hazards considerations.

' This proposed amendment does not involve a significant relaxation of the criteria used , to establish safety limits, a significant relaxation of the bases for the limiting safety system settings or a significant relaxation of the bases for the limiting conditions for operations. Therefore, based on the guidance provided in the Federal Register and the criteria established in 10 CFR 50.92(c), the proposed change does not constitute a significant hazards consideration.

ATTACHMENT D ENVIRONMENTAL ASSESSMENT STATEMENT APPLICABILITY REVIEW
~
Comed has evaluated the proposed amendment against the criteria for identification of licensing and regulatory actions requiring environmental assessment in accordance with 10 CFR Part 51.21. It has been determined that the proposed changes meet the criteria for categorical exclusion as provided for under 10 CFR Part 51.22(c)(9). This conclusion has been determined because the changes requested do not pose significant hazards considerations or do not involve a significant increase in the amounts, and no significant changes in the types of sny effluents that may be released off-site. Additionally, this request does not invclve a significant increase in individual or cumulative occupational radiation exposure. i t 1 I l _ _}}
