UNITED STATES OF AMERICA NUCLEAR REGULATORY COMMISSION Before the Atomic Safety and Licensing Board Before Administrative Judges:

James L. Kelley, Chairman Dr. Peter A. Morris Dr. Richard F. Foster In the Matter of )

) Docket Nos. 50-254-OLA COMMONWEALTH EDISON COMPANY ) 50-265-OLA (Quad Cities Station, ) (Spent Fuel Pool Modificationi Units 1 and 2) )

ORDER By our Order dated March 24, 1982, the parties in this proceeding were instructed to complete settlement discussions and report their results to the Atomic Safety and Licensing Board (" Licensing Board") no later than April 20, 1982. The date for completing settlement dis-cussions was subsequently extended from April 20 to April 23, 1982. On April 23, 1982, the Licensing Board participated in a conference call with the representatives of Commonwealth Edison Company (" Applicant") , the Nuclear Regulatory Commission Staff ("NRC Staf f") , and Quad Cities Alliance for Safe 1

Energy and Survival and Citizens for Safe Energy ("Intervenors") .

The results of the settlement discussions were reported to the Licensing Board at this time.

, a There are currently four contentions remaining at issue in this proceeding: Contention 5 (occupational expo-sure), Contention 6 (bowed fuel rods and fuel channels),

Contention 8 (quality assurance), and Contention 9 (struc-tural qualification of proposed racks for Safe Shutdown and Operating Basis Earthquakes). Intervenors verbally requested leave to withd raw Contention 9 prior to the April 23, 1982 conference call. In addition, the Licensing Board had deferred ruling on Contention 2 (alternatives) in our Order of October 27, 1981 until the NRC Staff's Environmental Impact Appraisal was available. The NRC Staff's Safety Evaluation Report (" SER" ) and Environmental Impact Appraisal

(" EIA" ) were issued April 9, 1982. No comments on the SER and EIA were received from Intervenors.

During the course of the April 23, 1982 conference call, I'ntervenors requested leave to: (1) withdraw all contentions remaining at issue in this proceeding, including proposed Contention 2; and (2) withdraw their original requests for hearing. At the conclusion of the conference call, the Licensing Board asked the NRC Staff to supply the technical information it had provided the Intervenors during the settlement discussions which had led to Intervenors' requests for withdrawal. The Licensing Board also requested Applicant to supply the procedures drafted in response to Contention 8, which will be used during the reracking operation.

This information has been received from the NRC Staff and Applicant, and has been reviewed by the Licensing Board.

r d n On the basis of the April 23, 1981 telephone conference discussion, the NRC Staff's technical submittals, Applicant's draft reracking procedures, the SER and EIA, and the present posture of the case, the Licensing Board orders:

1. The contentions remaining at issue in this proceeding, Contentions 5, 6, 8 and 9, and proposed Conten-tion 2, are withdrawn.

2. The Intervenors' Requests for Hearing are withdrawn.

3. This proceeding involving Commonwealth Edison Company's and Iowa-Illinois Gas and Electric Company's request to amend the operating licenses for the Quad Cities Station, Units 1 and 2, in order to increase these units' spent fuel pools' storage capacity, dated March 26, 1981, is hereby terminated.

4. In deciding to grant Intervenors' requests to withdraw and in making our decision to terminate this proceeding, the Licensing Board has relied on Applicant's commitment to submit the final approved procedures which i

will govern the reracking operation to the NRC Senior Resi-dont Inspector at the Quad Cities Station prior to commencement of the reracking operation.

5. Wherefore, it is ORDERED, in accordance with I

the Atomic Energy Act, as amended and the regulations of the Nuclear Regulatory Commission, that the Director of Nuclear

F

. N. '

Reactor Regulation is authorized to make appropriate findings in accordance with the Commission's regulations and to issue the appropriate license amendments authorizing the requested replacement of spent fuel storage racks at the Quad Cities Station.

6. It is further ORDERED, in accordance with 10 CFR 2.760, 2.762, 2.764, 2.785 and 2.786, that this Order shall be effective immediately1/ and shall constitute the final action of the Commission forty-five days after the issuance thereof, subject to any review pursuant to the above-cited Rules of Practice.

7. Exceptions to this Order may be filed within ten (10) days after service of this Order. A brief in support of the exceptions shall be filed within thirty (30) days thereafter [ forty (40) days in the case of the Staff].

Within thirty (30) days of the filing and service of the brief of the Appellant [ forty (40) days in the case of the Staff], any other party may file a brief in support of, or opposition to, the exception.

IT IS SO ORDERED.

d. Adjust Belleville washer spring packages and sling lengths shown

! on JOC drawing E-7281.

e. Gradually load the rods until the Belleville washer spring assemblies deflect 3/8 inch.

-l l

QFP 1100-4 R2vicien 1

f. During lifting, care must initially be taken that lifting rods are O- equally loaded. Difference in deflection of the Belleville washer spring assemblies should be w'ithin 3/8 inch of each other. If this deflection is exceeded, readjust length of turnbuckles until the lifting yoke is level to within this limit.

NOTE The above step is performed to initially level the lifting yoke. Additional adjust-ments are performed by adjusting the Belleville washer spring assembly nuts.

g. Gradually increase loading of the crane and check that the Belleville washer spring assemblies deflect to within 3/8 inch of each other until rack is free of floor and supported by the Belleville washers in a 'noncompressed condition.
