SAFETY EVALUATION BY THE_QfE CE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO.122 TO FACILITY OPERATING LICENSE NO. DPR-19 AND AMENQ,MJNi NO.117 TO FACILITY OPERATING LICENSE N0. DPR-25 COMMONWEALTH EDISON COMPANY DRESDEN NUCLEAR POWER STATION. UNITS 2 AND 3 DOCKET NOS. 50-237 AND 50-249 1.0 I NTPDUC T ION By letter dated September 2,1992, Commonwealth Edison Company (Ceco, the lic w ee) requested an amendment to Facility Operating License Nos. DPR-19 and idR-25 for Dresden Nuclear Power Station, Units 2 and 3.
The proposed amendment would delete Table 3.7.1, " Primary Containment Isolation," and modify Section 3/4.7,D, per the guidance contained in Generic Letter (GL) 91-08, of the Dresden Technical Specifications (TS).
In addition, an editorial change has been proposed that will eliminate an exemption from the TS that has expired and is no longer needed.
2.0 EVALUATION The licensee has proposed deletion of Table 3.7.1, where referenced in TS Section 3/4.7.D.
This table provides a reference to the valves that specifically perform the primary containment isolation function in this section of the TS.
However, since no specific reference to the valves 1.isted l
in table is made in the TS only minor changes to the TS have been proposed to support the table deletion.
Since the valves listed in the Sble are not specifically referred to, relative to an operability or surveillance require-ment, the staff finds that the proposed deletions are primarily administrative in nature and do not alter the requirercents set forth in the existing TS.
Since the proposed deletions are also consistent with the guids.nce contained in GL 91-08 the staff finds the proposed table deletion acceptable.
With the removal of Table 3.7.1, the licensee has proposed to delete the references to the table in Section 3/4.7.D of the TS. The licensee has also l
committed to include the valves currently contained in the table within the i
Dresden Administrative Technical Requirements (DATR) to retain administrative control.
Dresden Administrative Procedure 02-20, provides the guidelines for the control and use of DATR's. Any changes to DATR's will be reviewed and approved by the Onsite Review and Investigative Function using the 10 CFR 50.59 change process.
The licensee has also stated TS Table 3.7.1 wiil become a DATR, which will refer to TS 3/4.7 to assure compliance with TF for 9302230310 930211 PDR ADOCK 05000237 l

3.7,0.2.
Since these proposed changes-are also administrative in nature and consistent with the guidance contained in GL 91-08,-- the staff-finds them 1
acceptable.
The licensee has proposed to delete the exemption of Reactor Building Closed :
Cooling Water (RBCCW) pathways from the requirements of 10_CFR 50, Appendix J, referenced in TS 3.7,A.2.b(1)(a) and 3.7.A.2.b(2)(a) because it has expired.
and is, therefore, no longer in effect.
Since this exemption has expired-this' TS change-is administrative-in nature and, therefore,'the staff finds it-acceptable.
