SAFETY EVAL,UATION BY THE OTFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO.142 TO FACILITY OPERATING LICENSE NO. DPR-46 NEBRASKA PUBLIC POWER DISTRICT i
COOPER NUCLEAR STATION DOCKET NO. 50-298
1.0 INTRODUCTION
By letter dated July 2,1990, as supplemented by letters dated March 8, and
-April 19, 1991, Nebraska Public Power District (the licensee) submitted a g
request for changes.to the Cooper Nuclear Station Technical Specifications if (TS).
The requested changes would: remove cycle-specific reactor physics-parameters from the TS and incorporate them into a new document called the Core Operating Limits-Report.
The amendment was requested in response to Generic Letter 88-16. The March 8,:end April 19,:1991, letters provided clarifications i-and. modifications to various proposed TS pages that did not change the action noticed or. affect the initial proposed no significant hazards consideration b
determination.-
2.0 EVALUATION Thel licensee'sl proposed changes to the TS ere in accordance with the guidance L
provided by Generic Letter 88-16 ano are addressed below.
l
-(1) The Definition section of the TS was modified to include a definition of the Core Operating Limits Report (COLR) that requires cycle / reload-specific parameter limits to be established on a unit-specific basis _in accordance-with NRC. approved methodologies that maintain the limits of the safety analysis. -The definition notes that plant operation within these limits is:adoressed by. individual specifications.
s;) The following specifications were revised to replace the values-of cycle-specific parameter limits with-a reference to the COLR that provides these limits.=
-(a). ' Specification' 3.11. A.and Bases 3.11. A The Average Planar Linear Heat Generation Rate (APLHGR)-limits for this: specification and for these bases are specified in the COLR.
(b) Specifications 3.11.B. 2.1.A.1.a.and 2.1.A.1.d The-linear Heat Generation Rate (LHGR) limits for these specifications are specified in the COLR.

i
,. 1 (c). Specification 3.11.C The Minimum Critical Power Ratio (MCPR) operating limits and the-MCPR flow adjustment factor-(k ) for this. specification are specified in the COLR.
f (d)_ Specification Table 3.2.C The scoop tube set point (N) for the Rod Block Monitor (RBM)' upscale
-(flow bios) trip level setting is specified in the COLR.
(3) So-cification 6.5.1.G was added to tiie reporting requirements of the Aaministrative Ccntrols section of the TS.
This specification requires that the COLR be submitted, upon issuance, to the NRC Document Control Desk with copies to the Regional Administrator and Resident In:pecter.
The-report provides the values cf cycle-specific parameter limits that are applicable for the current fuel cycle.
Furthermore, these specifications require that_ the values of these limits be established using NRC approved methodologies and be consistent with all applicable limits of the safety analysis. The_ approved methodologies are the following:
(a) NEDE-24011-p-A, " General Electric Standard Application for reactor fuel,"'
(The1 approved revision at the time the reload analyses are performed.)
The approved revision number shall be identified in the COLR.
F_inally, the specification requires that all changes in cycle-specific parameter limits be documented in the COLR before each reload cycle or l_
remaining part of a reload cycle and submitted upon issuance to NRC, L
-prior to operation with the new parameter limits.-
l-
-On the basis of the review of the above items, the NRC staff concludes that the licensee provided an acceptable response to those items as addressed in the NRC guidance in Generic Letter 88-16 on modifying cycle-specific parameter limits in TS. Because plant operation continues to be limited in accordance with the values of cycle-specific parameter _ limits that are established using a
i NRC approved methodologies.: the NRC staff concludes that this change is administrative in nature and there is no impact on plant safety as a'
-consequence.- Accordingly, the' staff finds'that the proposed changes are acceptable.
As part of _ the implementation of Generic Letter 88-16, the staff has also reviewed a sample COLR that was provided by the licensee.
On the: basis cf this review, the staf f concludes that the format and content of the sample-L-
COLR'are acceptable.

. 3.0 ST AT E,CONSL'L ATION In accordence with the Commission's regulations, the Nebraska State official was notified of the proposed issuance of the omendment.
The State official had no comment.
4.0 ENVIRONMENTAL CONSIDERATION
These craendments involve a change with respect to instellation or use of a facility component located within the restricted area as defined in 10 CFR part 20.
the NRC staff hos determined thet the amendments involve no significant increest in the amounts, and no significant chnage in the types, of any effluents that may be released offsite, end that there is no significant increase in individual or comulative radiation exposure.
These amendments also involve changes in recordkeeping or reporting requirements.
The Commission has previously issued a proposed finding that the amendments involve no significant hazaros consideration and there has been no public comment on such finding (56 FR 6874). Accordingly, the amendments meet the eli for categorical exclusion set forth in 10 CFR 51.22(c)(9) and (gibility criteria 10). pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assess-ment need be prepored in connection with the issuance of these amendments.
5.0 CONCLUS10N ine Commission hos concluded, based on the 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, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public, principal Contributors: T.
