<E WASHINGTON, D. C. 20565 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO.115 TO FACILITY OPERATING LICENSE NO. DPR-29 AND AMENDMENT NO.111 TO FACILITY OPERATING LICENSE NO. DPR-30 COMMONWEALTH EDIS0N COMPANY AND IOWA-ILLINDIS GAS AND ELECTRIC COMPANY QUAD CITIES NUCLEAR POWER STATION, UNITS 1 AND 2 DOCKET NOS. 50-254/265
1.0 INTRODUCTION
l By letter dated November 15, 1988, Commonwealth Edison Company (Ceco, the licensee) submitted an application to amend the Quad Cities Nuclear Power Station (QCNPS)TechnicalSpecifications(TS). The proposed amendments to DPR-29 and DPR-30 would change TS to: 1) delete tabular listings of individual
'. safety-related snubbers, 2) delete all references made to hydraulic snubbers, and 3) correct editorial and typographical errors.
2.0 EVALUATION Deleting the tables of safety-related snubbers from TS was endorsed by the NRC in Generic Letter (GL) 84-13 dated May 3, 1984. According to GL 84-13, as long as all safety-related snubbers were properly identified and tracked, they need not be listed in TS. The licensee only needs to specify in TS that snubbers are required to be operable for supporting safety-related systems.
Removing snubber tables from the TS, was intended to eliminate the large number
- of unnecessary amendments by licensees whenever snubbers were added, deleted, or modified. However, GL 84-13 did not intend for licensees to revise the operational, surveillance, or record keeping requirements of safety-related snubbers. Furthermore, even though they would no longer be in TS, any subsequent changes in snubber quantities, types, or locations would be considered a change to the facility, and such changes are subject to the provisions of 10 CFR 50.59.
CECO proposed to delete Table 3.6.-1, " Safety Related Shock Suppressors (Snubbers)," and replace all references to this table with the statement that specifies "all snubbers on safety-related systems." The record of installed safety-related snubbers will be maintained within the control of QCNPS administrative procedures in order to comply with the record keeping requirements of TS 4.6.1.1.
CECO did not significantly revise any of the operational, surveillance, or record keeping requirements of TS. The NRC staff concludes their proposed deletion of TS Table 3.6-1 and associated reference changes are consistent with the guidance provided in GL 84-13, and therefore acceptable, since the operational, surveillance and recordkeeping requirements for safety-related snubbers will remain essentially unchanged.

m,o' The test requirements of hydraulic snubbers are no longer needed by QCNPS as the total po)ulation of safety-related snubbers consist of mechanical snubbers.
Therefore, tie proposal to delete all reference to hydraulic snubbers is acceptable to the NRC staff.
Several typographical and editorial corrections were proposed by CECO in their amendment. The NRC staff considers these to be acceptable.
CECO should ensure the QCNPS FSAR is properly updated to reflect any and all of the aforementioned changes.
3.0 ENVIRONMENTAL CONSIDERATION
These amendments involve changes to a requirements related to the use and surveillance of facility components located within the restricted area as defined in 10 CFR Part 20. The staff has determined that these amendments involve 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 Commission has previously issued a proposed finding that these amendments involve no significant hazards consideration and there has been no public comments on such finding. Accordingly, these amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) and 10 CFR 51.22(c)(10).
Pursuantto10CFR51.22(b)noenvironmentalimpactstatementnor environmental assessment need be prepared in connection with the issuance of these amendn.ents.
4.0 CONCLUSION
The staff has concluded, based on the considerations discussed above, that:
will not be endangered by operation in the pro)osed manner, and (2) public (1) there is reasonable assurance that the health and safety of the such activities will be conducted in compliance wit 1 the Commission's regulations, I
and (3) the issuance of these amendments will not be inimical to the common i
defense and security nor to the health and safety of the public.
