1.0 INTRODUCTION
In a letter dated December 22, 1987, Comonwealth Edison Company (the licensee), submitted an application for license amendments to change the Technical Specifications (TS) for the Quad-Cities Nuclear Power Station (QCNPS).
These amendment requests proposed revising TS 3.2.D.3 to change the refueling floor radiation monitors trip set point from 100 mR/hr to 5, ion (to the Assistant Superintendent level) for approving all 100 mR/hr, and TS 6.2.C.1 to upgrade the highest level of authorizat procedures identified in TS 6.2.A and 6.2.8.
During the course of our review, the staff referred to Title 10 of the Code of Federal Ragulations - Chapter I, and the Technical Specifications for QCNPS, Univ..L and 2.
2.0 EVALUATION Proposed amendments to TS 3.2.D.3 would change the trip setpoint for the refueling floor radiation monitors from 100 mR/hr to < 100 mR/hr.
This change is consistent with the general philosophy of prescribing TS setpoints in terms of a limiting value rather than an absolute value.
i The use of a limiting value permits a setpoint margin to be established for accommodating instrument drift and calibration uncertainties.
This provides assurance that the limiting value will not be exceeded. The staff has reviewed this change and concurs there is no adverse impact on safety.
Therefore, this proposed change is acceptable.
Proposed amendments to TS 6.2.C.1 raise the highest level of authorization for procedures, and changes to all procedures, identified in TS 6.2.A. and 6.2.B to the Assistant Superintendent level.
Current TS requirements for review and approval varied the level of authorization dependent upon procedure type.
This proposed change would provide a consistent level of authorization for approving procedures, and their changes, for all procedures identified by TS 6.2.A and 6.2.8.
The staff determined this change is administrativo in nature, has no adverse impact on safety, and, therefore, is acceptable.

3.0 ENVIRONMENTAL CONSIDERATION
The amendment to TS 3.2.0.3 involves a change to the requirements for use of a facility component located within the restricted area as defined in 10 CFR Part 20. The staff has determined this amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure. The Ccmission previously issued a proposed finding that this amendment involves no significant hazards consideration and there has been no public coment on such finding. Accordingly, this amandt.ent meet the eligibility criteria for categorical exclusion set fort.h in 10 CFR 51,22(c)(9). The amendment to TS 6.2.C.1 concerns administrative procedures and, therefore, is eligible for categorical exclusior under 10CFR51.22(c)(10).
Pursuant to 10 CFR 51.22(b) no environmental impact statement nor environmental assessment need be prepared in connection with the issuance of these amendments.
4.0 CONCLUSION
The staff concludee, based upon considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Comission's regulations and the issuance of these amendments will not be inimical to the connon defense and security nor to the health and safety of the public.
