NRC Bulletin 90-02 (Bulletin) requested that all Boiling Water Reactor (BWR)
Licensees address the effect of fuel channel bow on thermal margins in BWRs, particularly the bow of channels that are being reused on a second bundle. Reference 1 provided Commonwealth Edison Company's (CECO) response to the Bulletin for LaSalle County Station (LeSalle). The response indicated that, although CECO no longer places irradiated channels on new/ fresh fuel assemblies, previous channel management practices included the reuse of channels. Consequently, LaSalle 1 Cycle 6 (currently scheduled to begin December 28,1992) will use some fuel channels which had been previously installed on other fuel bundlos from Cycle t These channels had a previous single cycle of operation.

i The attachment to this letter presents the evaluation performed by CECO to
' address the thermal margin impact of the residual reused channels during Cycle 6.
This evaluation is based on the results of the LaSai,e 1 Cycle 5 analysis, which was submitted to the NRC in Reference 2 and approved in Reference 3, and the LaSalle 2 Cycle 5 analysis, which was submitted to the NRC in Reference 4 and approved in Reference 5. In order to minimize their potential effects, the 156 residual reused channels will be loaded near the core periphery and are arojected to have substantial margin to limits. As discussed in the attachment, CECO aelieves the large Cycle 6 margins coupled with the previous Cycle 5 analysis (which bounds this cycle) are responsive to the concerns expressed by your staff in the Bulletin.
Please direct any questions or comments on this letter to this office.

Attachment Evaluation of the Effect of Residual Reused Channels on Thermal Margins for LaSalle 1 Cycle 6
Background:
Reference 1, which presented Commonwealth Edison's (Edison) response to NRC Bulletin 90-02 for its Bolling Water Reactor Stations, indicated that although Edison no longer places irradiated fuel channels on fresh fuel assemblies, previous channel management practices had included the reuse of channels. As a result, channels from the LaSalle County Station initial core discharge batch were placed on the fresh fuel assemblies that were loaded in LaSailo 1 Cycle 3, as discussed in Reference 1.
These channels had received a single cyc:e of irradiation, yleiding channel exposures from 2 to 14 GWD/MTU, prior to their placement on the LaSalle 1 Cycle 3 reload fuel. Assemblies from this reload continue to be resident in the projected LaSalle 1 Cycle 6 loading.
Channel bow is primarily caused by differential neutron flux across the lattice. C-lattice plants, such as LaSalle County Station, have uniform water gaps around the assemblies and hence experience less channel bow as a function of exposure relative to comparable D-lattice plants. This leads to a smeller impact on local 3eaking, and hence Minimum Critical Power Ratio (MCPR) and L near Heat Generation (LHGR) margins, as a result of channel bow for C-lattice plants.
Projected LaSalle 1 Cycle 6 Channol Confguration:
The projected LaSalle 1 Cycle 6 core configuration is shown in Figure 1. This figure shows the location of the reused channels, the end of Cycle 6 projected channci exposure, and the end of Cycle 6 projected fuel assembly exposure. For reference purposes, the assemblies w;th reused channels are listed in Table 1 in order of decreasing end of Cycle 6 channel exposure. The projected end of Cycle 5 exposure is based on the latest projection. Actual bundle and hence channel exposures may increase up to 0.20 GWD/MTU because the unit is operating at a higher capacity factor than predicted. Therefore, the values in Figure 1 and Table 1 may increase by that amount.
ZNLD/1932/21
It can ba se:n from Figuro 1 that tha fuel essembli:s with r used chann:Is aro load:d within thrce rows of tha coro periph ry as the result of a deliberate effort by Edison nuclear design engineers to minimize the number of residual reused channels in limiting, high-power locations while maintaining core symmetry. As a result, 156 assemblies which had received reused channels when they were originally loaded will remain in LaSalle 1 Cycle 6 but are all within three rows of the periphery.
As seen in Table 1, maximum channel exposure at the end of Cycle 6 is significantly below the maximum channel exposure 54 GWD/MTU which was used in the GE generic channel bow methodology, Reference 4. Assuming Cycle 5 and Cycle 6 run at I
100% capacity, the and of Cycle 6 channel exposures are still below the maximum value used in the GE analysis.
Chan el Bow Evaluation:
General Electric performed a cycle-specific analysis for the residual reused channels in LaSalle 1 Cycle 5. This was evaluated and submitted by Edison to the NRC in Reforence 2 and approved by the NRC in Reference 3. The cycle-specific analysis was required due to the number of reused channels in central, limiting locations.
This analysis determined the ap aropriate value of bow to be used to adjust the critical power corre ation's R-factors for the various assemblies in the core by evaluating the past exposure history of the reused channels present in LaSalle 1 Cycle 5. R-factors are a location-weighted function of the local pin powers in a bundle.
The LaSalle 1 Cycle 5 evaluation was only performed for reused -
channels which were present on the interior, limiting assemblies.
Cells which are located within four rows of the core periphery were not included due to the large degree of margin in these low power regions.
The bundles with the reused channels are pro,ected to have at least 50% margin to the MCPR Operating Lim t and at least 55%
margin to the LHGR Limit at the most limiting point in LaSalle 1 Cycle 6. Therefore, consistent with the LaSalle 1 Cycle 5 analysis and evaivation, these assemblies will not be rechanneled or specifically analyzed due to their substantial margin to thermal limits.
R-Factor Adjustment:
Since there will be no reused channels in the interior, potentially limiting area of the core, and the maximum projected end of Cycle 6 channel exposure is less than the maximum value in the GE generlc channel bow analysis (Roference 4) of 54 GWD/MTU, the application for the NRC approved GE core average bow technique for single bundle channels, as described in Reference 4, is appropriate. Edison will apply an R factor set consistent with this method. This aoproach was areviously used for LaSalle 2 Cycle 5, submitted in Reference 5 anc revicwed and approved by the NRC (Reference 6).
ZNLD/1932/22
MCPR Safety Umit:
A potentid impact of channel bow is an increase in the MCPR Safety Limit due to increased measurement uncertainties. GE evaluated this for the LaSalle 1 Cycle 5 loading in Reference 2 and concluded that there would be no impact on the MCPR Safety Limit since the spread in the channel bow data was within the tolerances used in the generic methodology, Reference 4. Since the LaSalle 1 Cycle 5 loading bounds the LaSalle 1 Cycle 6 loading in terms of number and location of reused channels, and the maximum end of Cycle 6 channel ex posure is less than the maximum value in the GE generic methocology, no adjustment of the MCPR Safety Limit is required to ensure fuel cladding integrity. This approach was previously used for LaSalle 2 Cycle 5 suomitted in Reference 5 and reviewed and approved by the NRC (Reference 6).
==
Conclusion:==
To summarize, the single previous cychs of exposure (on different l
assemblies) of the remaining 156 reslaual reused channels in the LaSalle 1 Cycle 6 core does not present a challenge to the LHGR limit, the MCPR Operating Limit, or the MCPR Safety Limit. They will be loaded into non-limiting locations on or near the core periphery.
During cycle operation, all assemblies in the core will be modeled using an R-factor adjustment strategy consistent with the GE generic channel bow methodology. These steps will ensure that the MCPR Safety Limit and LHGR design limitas are protected throughout LaSalle 1 Cycle 6 even in the event of a limiting Abnorma! Operating Occurrence.
As indicated in the Reference 1 resporise to NP,C Bulletin 90-02, Edison nas discontinued the previous praciice of channeling fresh fuel with previously irradiated channels and anticipates that all res; dual reused channels will be completely discharged at the end of Cycle 6 on Unit 1 and the end of Cycle 6 on Unit 2. Until that time, Edison will continue to minimize the number of residual reused channels during the core loading development, and will load all reused channels only ir locations which are clearly non-limiting, n
