Examples of these limits/restrictions include power dependent rod insertion limits, and limits of FQ(Z) and FAH, among others. Technical Specification changes and NRC approval were required as specific numerical values for these limits/restrictions were revised. If these changes were frequent, e.g. on a cycle-specific basis, or if they were needed on accelerated schedules, considerable administrative burdens were placed on both the NRC and on utility personnel.
8.3.2 To reduce this burden, the COLR concept was developed in which specific numerical values for certain core operating limits and/or restrictions would be removed from the Technical Specifications and relocated to a COLR document. Using NRC approved methodologies, numerical values for these operating limits and/or restrictions can be updated on an as-needed basis (e.g. each cycle) by simply revising the COLR with appropriate review and notification to the NRC, hence, revisions to the Technical Specifications are not required.
8.3.3 The NRC endorsed the COLR concept by encouraging licensees to develop such a document in Generic Letter 88-16 which provided guidance for relocation of specific numerical values for various core operating limits and/or restrictions to a COLR and indicated that these values could be changed without prior NRC approval so long as an NRC-approved methodology is followed. Future changes and updates would be allowable provided an Evaluation is performed in accordance FMP-001 Rev. 23 Page 8of24
with the provisions of 10CFR 50.59, the COLR is suitably revised, and the NRC is promptly informed of the revision.
8.3.4 The use of a COLR at H. B. Robinson was accepted by the NRC per License Amendment 141. The amendment established requirements for a cycle-specific COLR and for notification of the NRC (ITS 5.6.5.d) when any revisions or supplements (beginning of cycle or midcycle) are made.
Since the COLR is cycle-specific, the COLR will be revised at least once per cycle, that is, at the beginning of the cycle.
8.4 Contents of the H.B. Robinson Unit 2 COLR 8.4.1 Technical Specification ITS 5.6.5.a requires the following cycle-specific core operating limits be established and documented in the Core Operating Limits Reports

8.4.3 The core operating limits shall be determined such that all applicable limits (e.g., fuel thermal mechanical limits, core thermal hydraulic limits, Emergency Core Cooling Systems (ECCS) limits, nuclear limits such as SDM, transient analysis limits, and accident analysis limits) of the safety analysis are met (TS 5.6.5.c).
FMP-001 Rev. 23 Page 9 of 24
8.5 Revisions to The COLR 8.5.1 Nuclear Fuels Management & Safety Analysis Section (NFM&SA) shall review and recommend for implementation any changes to the COLR.
The review is normally documented in an EC including any required Owner's Reviews, calculations and other reviews. The use of NRC approved methodologies is also confirmed in the EC. Changes recommended by NFM&SA are normally transmitted to the plant via a memo recommending the revision of the COLR.
8.5.2 Once NFM&SA recommends a revision to the COLR, a Reactor Engineer shall prepare a revision to FMP-001 in accordance with the requirements of PRO-NGGC-0204.
8.5.3 Other plant procedures shall be reviewed to determine if they require revision in order to implement the revised COLR. At a minimum, the procedures listed in ATTACHMENT 10.2 shall be reviewed.
8.5.4 Any required procedure revisions or new procedures necessary to incorporate the change to the COLR shall be completed by the effective date of the COLR change.
8.5.5 The proposed revision of the COLR shall be submitted to the PNSC for review.
8.5.6 The PNSC shall review the proposed revision to the COLR and concur with the changes prior to their implementation in accordance with UFSAR Section 17.3 Appendix A Item A.1.6.6.j.
8.5.7 Upon approval of the COLR revision, Licensing/Regulatory Programs shall notify the NRC per ITS 5.6.5.d within 30 days.

ATTACHMENT 10.2 Page 1 of 1 PROCEDURES POTENTIALLY AFFECTED BY COLR REVISIONS Revisions to the COLR may require that revisions be made to other plant procedures. At a minimum the following procedures should be reviewed todetermine if they must be revised:
APP-005 GP-002 CP-0!0 GP-003 EST-002 GP-006 EST-003 GP-009-1 EST-028 GP-009-2 EST-048 GP-009-3 EST-049 GP-009-4 EST-050 GP-009-5 EST-105 GP-010 EST-146 LP-551 FMP-009 LP-552 FMP-012 OP-003 FMP-014 OP-910 FMP-019 OMP-003 FHP-003 PLP-100 Station Curve Book ERFIS CAOC Software NFP-NGGC-0003 NFP-NGGC-0018 The procedures listed above are those that are typically affected by COLR revisions; however, other procedures may also be affected.
