1.0 DESCRIPTION
This letter is a request by Indiana Michigan Power Company (I&M) to amend Facility Operating Licenses DPR-58 and DPR-74 for the Donald C. Cook Nuclear Plant (CNP) Units 1 and 2. The proposed changes would revise the near-end of life (EOL) Moderator Temperature Coefficient (MTC) Surveillance Requirement (SR) by placing a set of conditions on' core performance, which if met, would allow conditional exemption from the required MTC measurement. The conditional exemption will be determined on a cycle-specific basis by considering the margin predicted to the surveillance requirement MTC limit and the performance of other core parameters, such as beginning of life (BOL) MTC measurements and the critical boron concentration as a function of cycle average burnup. The conditional exemption would minimize disruptions to normal plant operations. Plant safety criteria will not be compromised by the conditional exemption of this one measurement. No changes to the Technical Specification (TS)
Bases will be required as a result of the proposed amendment.
I&M requests approval of the proposed amendment by December 1, 2005. I&M requests that the amendment allow a 15 day implementation period.
2.0 PROPOSED CHANGE
By separate correspondence, I&M has previously proposed conversion of the CNP Current Technical Specifications (CTS) to the Improved Technical Specifications (ITS) specified in NUREG-1431. Implementation of the ITS is expected prior to implementation of the changes proposed in this amendment request. I&M has therefore provided copies of both the CTS and the current draft ITS pages that are affected by this proposed amendment.
CTS Changes SR 4.1.1.4.b is modified to suspend the MTC measurement if the model benchmark criteria and Revised Prediction specified in the Core Operating Limits Report (COLR) are satisfied.
WCAP-13749-P-A, "Safety Evaluation Supporting the Conditional Exemption of the Most Negative EOL Moderator Temperature Coefficient Measurement," is added to the list of references for the COLR in TS 6.9.1.9.2.
ITS Changes SR 3.1.3.2 is modified to suspend the MTC measurement if the model benchmark criteria and Revised Prediction specified in the COLR are satisfied.
WCAP-13749-P-A, "Safety Evaluation Supporting the Conditional Exemption of the Most Negative EOL Moderator Temperature Coefficient Measurement," is added to the list of references for the COLR in TS 5.6.5.
'I,- .. to AEP:NRC:5132 Page 3 In summary, the proposed change will revise TS governing near-EOL MTC by placing a set of conditions on core performance, which if met, would allow conditional exemption from the required MTC measurement. The conditional exemption will be determined on a cycle-specific basis by considering the margin predicted to the surveillance requirement MTC limit and the performance of other core parameters, such as beginning of life MTC measurements and the critical boron concentration as a function of cycle average burnup.
3.0 BACKGROUND
One of the controlling parameters for power and reactivity increases is the MTC. The requirements of TS 3.1.1.4 ensure that the MTC remains within the bounds used in the applicable Updated Final Safety Analysis Report Chapter 14 accident analysis. This, in turn, ensures inherently stable power operations during normal operation and accident conditions.
The TS place both Limiting Condition for Operation (LCO) and SR constraints on the MTC, based on the accident analysis assumptions for the moderator density coefficient. A positive moderator density coefficient corresponds to a negative MTC. The most negative MTC LCO limit requires that the MTC be less negative than the specified limit for the all rods withdrawn, EOL, rated thermal power condition. To demonstrate compliance with the most negative MTC LCO, the surveillance requires verification of the MTC after 300 ppm equilibrium boron concentration is reached. Because the Hot Full Power (HFP) MTC value will gradually become more negative with further core burnup and boron concentration reduction, a 300 ppm MTC surveillance value should be less negative than the EOL LCO limit. To account for this effect, the 300 ppm MTC surveillance value is sufficiently less negative than the EOL LCO limit value, providing assurance that the LCO limit will be met as long as the 300 ppm MTC surveillance criterion is met.
Currently, the TS require measurement of MTC at BOL to verify the most positive MTC limit and near-EOL to verify the most negative MTC limit. At BOL, the measurement of the isothermal temperature coefficient is relatively simple to perform since it is done at hot zero power isothermal conditions and is not complicated by changes in the enthalpy rise or the presence of xenon. The measurement made near EOL is performed at or near HFP conditions.
MTC measurements at HFP are more difficult to perform due to 1) small variations in soluble boron concentration, 2) changes in xenon concentration and distribution, 3) changes in fuel temperature, and 4) changes in enthalpy rise created by small changes in the core average power during the measurement. Changes in each of these parameters must be accurately accounted for when reducing the measurement data, or additional measurement uncertainties will be introduced. Even though these additional uncertainties may be small, the total reactivity change associated with the swing in moderator temperature is also relatively small. The resulting MTC measurement uncertainty created by even a small change in power level can then become significant and, if improperly accounted for, can yield misleading measurement results.
Each MTC measurement presents a perturbation to normal operation and to the reactor itself, requiring dedicated time by control room operators for most of a shift and a significant amount of primary coolant water during the evolution. An alternate method is proposed for use at CNP to AEP:NRC:5132 Page 4 to minimize disruption to normal plant operations. The MTC measurement is replaced by a design calculation of the core MTC if predefined requirements are met.
The proposed change would allow modification of the EOL MTC SR by placing a set of conditions on core performance. If these conditions are met, i.e., the specified revised prediction of the MTC and limits for several core parameters measured during the cycle are within specified bounds, the surveillance measurement would not be required.
4.0 TECHNICAL ANALYSIS
The conditional exemption from the HFP near-EOL 300 ppm MTC measurement does not impact the safe operation of CNP. The safety analysis assumption of a constant moderator density coefficient and the actual value assumed will not change. The TS Bases for, and the values of, the most negative MTC LCO and SR are not altered. Instead, a revised prediction is compared to the surveillance MTC to determine if the limit is met. The method for calculating the revised prediction is consistent with the approved methodology of WCAP-13749-P-A (Reference 1).
The methodology for the proposed change was submitted to the U. S. Nuclear Regulatory Commission (NRC) as Westinghouse topical report WCAP-13749 in May 1993. In October 1996, the NRC determined the report to be acceptable for referencing in license applications to the extent specified and under the limitations stated in the Brookhaven technical evaluation report and the NRC staff's safety evaluation report. Reference 1 includes all of these documents.
The topical report was approved by the NRC with two requirements:
. only PHOENIX/ANC calculation methods are used for the individual plant analyses relevant to determinations for the EOL MTC plant methodology, and
. the predictive correction is reexamined if changes in core fuel designs or continued MTC calculation/measurement data show significant effect on the predictive correction.
CNP will meet both of these requirements. The PHOENIX/ANC calculation methods are used for the CNP core designs. Prior to use of the conditional elimination technique, CNP will confirm that core design changes and MTC calculation and measurement data do not show a significant effect on the predictive correction. If a significant effect is found, the use of the predictive correction will be reexamined.
All of the core performance benchmark criteria specified in WCAP-13749-P-A, which are confirmed from startup physics test results, from routine HFP boron concentration measurements, and from flux map surveillances performed during the cycle, must be met before the Revised Predicted MTC can be calculated per the prescribed algorithm in Reference 1.
Enhancement I&M is using NRC-approved WCAP-13749-P-A as the basis for this license amendment request.
I&M will meet all of the technical requirements in the approved WCAP, but proposes an enhancement to reduce regulatory burden for both the NRC and the licensee. I&M proposes not to submit a "Most Negative Moderator Temperature Coefficient Limit Report" (the Report) to to AEP:NRC:5132 Page 5 the NRC. There are two reasons for this. First, there is an inconsistency in the WCAP regarding the time frame of data collection and the submittal of the Report to the NRC. More importantly, the Report serves no apparent technical or business need. Each of these reasons is explained below. This enhancement has been accepted by the NRC through approval of similar TS amendments as listed in Section 8.0 of this amendment request.
First, Section 3.3.3 of the WCAP states:
The Technical Specification Bases of the most negative MTC LCO and SR and the values of these limits are not altered. Instead, a revised prediction is compared to the SR MTC to determine if the SR limit is met. The revised prediction is simply the sum of the predicted HFP 300 ppm SR MTC plus an AFD correction factor plus a predictive correction term. This algorithm is summarized in Table 3-3.
Table D-2 of the WCAP states that the algorithm for determining the revised predicted near-EOL 300 ppm MTC is (emphasis added):
The Revised Predicted MTC = Predicted MTC + AFD Correction +
Predicted Correction where:
Predicted MTC is calculated from Figure 1 [Predicted HFP ARO 300 ppm MTC Versus Cycle Burnup] at the burnup corresponding to the measurement of 300 ppm at RTP conditions...
Table D-3 of the WCAP provides an example worksheet for calculating the revised predicted near-EOL 300 ppm MTC. Two of the required data inputs for the worksheet (B. 1 and B.2) are used to calculate the AFD correction term in the algorithm (emphasis added):
B. 1 Burnup of most recent HFP, equilibrium MWD/MTU conditions incore flux map B.2 Measured HFP AFD at burnup (B. 1) % AFD Reference incore flux map I.D. Date:
However, Appendix A to the WCAP states that a new TS 6.9.1.7 is to be added (emphasis added):
6.9.1.7 The most negative MTC limits shall be provided to the NRC Regional Administrator with a copy to the Director of Nuclear Reactor Regulation, Attention:
Chief, Core Performance Branch, U. S. Nuclear Regulatory Commission, Washington, D.
C. 20555, at least 60 days prior to the date the limit would become effective unless otherwise approved by the Commission by letter. This report wtill include the data reauiredfor the determinationof the Revised Prediction of the 300 ppm/ARO/RTP MTC per WCAP-13749, "Safety Evaluation Supporting the Conditional Elimination of the Most Negative EOL Moderator Tempaerature Coefficient Measurement", May, 1993 (Westinghouse Proprietary).
to AEP:NRC:5132 Page 6 Because the Report would have to be submitted at least 60 days before reaching 300 ppm boron concentration, it cannot include the 300 ppm data required for determining the Revised Prediction. To meet the Report submittal requirement, the data to be used in calculating the revised predicted MTC may have to be taken 60 to 90 days prior to reaching 300 ppm boron.
The WCAP does not provide any method for adjusting the revised predicted MTC to account for data collected 60 to 90 days prior to 300 ppm, nor does it provide justification for using such early data in the calculation. Therefore, the requirement to submit the Report and the requirements for the data that go into the report are inconsistent.
More importantly, the Report serves no apparent technical or business need. The applicability restrictions in the WCAP, the algorithm, and the acceptance criteria of the proposed Report would be included in the station procedure governing the EOL MTC surveillance. There is no compelling reason that this particular surveillance should require notifying the NRC prior to performing the surveillance procedure.
5.0 REGULATORY SAFETY ANALYSIS 5.1 No Significant Hazards Consideration Indiana Michigan Power Company (I&M) has evaluated whether a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of Amendment," as discussed below:
- 1. Does the proposed change involve a significant increase in the probability of occurrence or consequences of an accident previously evaluated?
Response: No The probability or consequences of accidents previously evaluated in the Updated Final Safety Analysis Report (UFSAR) are unaffected by this proposed change because there is no change to any equipment response or accident mitigation scenario. There are no additional challenges to fission product barrier integrity.
Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No No new accident scenarios, failure mechanisms, or limiting single failures are introduced as a result of the proposed change. The proposed change does not challenge the performance or integrity of any safety-related system.
! ,, Z. to AEP:NRC:5 132 Page 7 Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.
- 3. Does the proposed change involve a significant reduction in a margin of safety?
Response: No The margin of safety associated with the acceptance criteria of any accident is unchanged.
The proposed change will have no affect on the availability, operability, or performance of the safety-related systems and components. A change to a surveillance requirement is proposed, but the limiting conditions for operation required by the Teclmical Specifications (TS) are not changed.
The Technical Specifications Bases are founded in part on the ability of the regulatory criteria to be satisfied assuming the limiting conditions for operation are met for the various systems. Conformance to the regulatory criteria for operation with the conditional exemption from the near-end of life moderator temperature coefficient (MTC) measurement is demonstrated and the regulatory limits are not exceeded. Therefore, the margin of safety as defined in the TS is not reduced.
Therefore, the proposed change does not involve a significant reduction in the margin of safety.
In summary, based upon the above evaluation, I&M has concluded that the proposed amendment involves no significant hazards consideration under the standards set forth in 10 CFR 50.92(c),
and, accordingly, a finding of "no significant hazards consideration" is justified.
5.2 Applicable Regulatory Requirements/Criteria 10 CFR 50.36 (c) (3), "Surveillance Requirements" stipulates that surveillances be performed to assure the necessary quality of systems and components be maintained, the facility operations will be within safety limits, and that the limiting condition for operations will be met.
The regulatory basis for TS 4.1.1.4, 'Moderator Temperature Coefficient," is to ensure that the value of the MTC remains within the limiting condition assumed in the CNP UFSAR accident and transient analyses.
In conclusion, based on the considerations discussed above, (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 Nuclear Regulatory Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health or safety of the public.

6.0 ENVIRONMENTAL CONSIDERATION
S A review has determined that the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure.
Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

These limits have been developed using the NRC-approved methodologies specified in Technical Specification 6.9.1.9.
2.1 Moderator Temperature Coefficient (Technical Specification 3/4.1.1.4) 2.1.1 The Moderator Temperature Coefficient (MTC) limits are:
The BOIJARO-MTC shall be less positive than or equal to the value given in Figure 1.
The EOIARO/RTP-MTC shall be'less negative than or equal to 4.1 OE-4 Akl/k/F.
