Cook Nuclear Plant Units 1 and 2 DECOMMISSIONING FUNDING STATUS REPORT In accordance with the requirements of 10 CFR 50.75(f)(1), Indiana Michigan Power Company, the licensee for Donald C. Cook Nuclear Plant (CNP), Units 1 and 2, hereby submits the attached report on the status of decommissioning funding. The recovery of decommissioning funds for the eventual decommissioning of CNP Units I and 2 is fully assured through cost of service regulation and the resulting contribution of funds into an external trust.
When projected to the current license expiration date for each unit, the Nuclear Decommissioning Trust balance is greater than the escalated Nuclear Regulatory Commission minimum cost of decommissioning, confirming compliance with the financial assurance requirements of 10 CFR 50.75.
This letter contains no new commitments.
If you have any questions on the report or decommissioning funding, please contact Ms. Susan D. Simpson, Regulatory Affairs Manager, at (269) 466-2428.

Nuclear Decommissioning Trust Fund Agreements Summary of 11 Significant Changes General Comments While the Minimum Value Decommissioning Cost Estimate under 10 CFR 50.75(c) reported on Schedule A is the information the Nuclear Regulatory Commission (NRC) has specified as appropriate for its purposes, Indiana Michigan Power Company (I&M) believes a broader and more comprehensive definition of, and provision for, nuclear decommissioning expenses is needed for its purposes.
For the past several years, I&M has periodically provided the Indiana and Michigan utility regulatory commissions site-specific studies containing a broader definition of nuclear decommissioning requirements.
These studies include the 10 CFR 50.75(b) and (c) costs, 10 CFR 50.54(bb) costs, and "greenfield" costs, versus only the required 10 CFR 50.75 costs.
These costs have been commingled in the decommissioning trust funds.
The site decommissioning studies have been presented in reports to the utility regulatory commissions.
The commissions have accepted these studies and have authorized recoveries for nuclear decommissioning based on their determinations, considering the reports presented, of appropriate recoveries for nuclear decommissioning using the more comprehensive definition. The currently estimated annual fund collections authorized for decommissioning are reported on Schedule C.
Attachment to AEP:NRC:7075 Page 2 Schedule A Indiana Michigan Power Company Nuclear Decommissioning Trust Fund Donald C. Cook Nuclear Plant Decommissioning Cost Estimates Minimum Value Per 10 CFR 50.75(c) 10 CFR 50.75(a) requires that each utility assure that there will be adequate funding for the decommissioning of the plant. 10 CFR 50.75(c) established a table of minimum values for the decommissioning funds, in January 1986 dollars, and it also set forth a method to adjust those values. Periodically, the NRC publishes NUREG-1307, "Report on Waste Burial Charges," and in that document, the data and more specific guidance is given regarding the method to be used to adjust the minimum amount to equivalent current amounts. The calculation in this report uses the burial cost escalation values and the method outlined in NRC NUREG-1307, Revision 12, to determine the minimum values.

$370,958,620 Total 738,737,595
Attachment to AEP:NRC:7075 Page 3 Schedule A Decommissioning Cost Estimate Calculation The first step of the decommissioning cost estimate calculation is to determine the 1986 base cost.
Donald C. Cook Nuclear Plant (CNP) Units I and 2 are rated at 3304 megawatt-thermal (MW,) and 3468 MWt, respectively. From 10 CFR 50(c)(1)(i), the cost is then based on the MWt output of each unit. For reactor power greater than 3400 MWt, the cost is $105 million. For reactor power from 1200 to 3400 MWt, the cost is calculated using this formula:
Cost = $(75 + 0.0088P) million.
Given P is the power level. So, for Unit I at 3304 MWt the cost is:
Cost = $(75 + 0.0088 x 3304) million
= $104.1 million.
For Unit 2, since the power level is greater than 3400 MWt, the cost is $105 million which is taken directly from the NRC's model.
So, the total 1986 base decommissioning cost for CNP is $104.1 + $105 million or $209.1 million.
The next portion of the analysis is to adjust the 1986 cost to the current year cost.
Using the formula:
Estimated Cost (Year X) = [1986 $ Cost] [A Lx + B E, + C B,]
Where A, B, and C are the fractions of the total 1986 $ costs that are attributable to labor (0.65), energy (0A13), and burial (0.22), respectively, and sum to 1.0. The factors L*, Ex, and B, are defined by:
Lx = labor cost escalation, January of 1986 to January of Year X E, = energy cost escalation, January of 1986 to January of Year X B, = burial cost escalation, January of 1986 to January of Year X, i.e., burial cost in January of Year X / burial cost in January of 1986.
The labor escalation factor is determined by U. S. Bureau of Labor Statistics (BLS) data using the "Employment Cost Index" and the NUREG-1307, Table 3.2, data for the Midwest region.
No 2007 data has been published, so fourth quarter 2006 data is used for 2007.
Attachment to AEP:NRC:7075 Page 4 Schedule A The energy cost escalation is determined by BLS data by using "Producer Price Indexes."
The energy term in the adjustment equation is made up of two components; industrial electric power (P),
and light fuel oil (F). E, is determined from the following equation for Pressurized Water Reactors:
E = 0.58P + 0.42F.
The values of P and F are taken from the BLS as described in NUREG-1307. The data from January were used, and is shown in Table 1. Also shown are the results of the calculations to determine E. The energy data for 2007 is BLS preliminary data.

The Labor adjustment factor is determined by multiplying the current year's cost index value by the applicable base labor adjustment factor, then dividing by the 2005 reference cost.
Per NUREG-1307, Revision 12, Table 3.2, the Midwest Labor Adjustment Factor is 2.13824.
(L2006 = 102.8*2.08/100.0)
The energy adjustment factor is determined by dividing each year's electric power (P) and light fuel oil (F) cost by the respective 1986 reference cost, then applying the allocation of.58Px +.42Fx (2007 Px = 170.8/114.2), (2007 Fx = 180.3/82), (2007 Ex =.58 (170.8/114.2) +.42 (180.3/82 =
1.790948)
The values for B, are taken directly from NUREG-1307, Revision 12, Table 2.1, using the data for South Carolina using waste vendors for disposition as a non-Atlantic Compact State. For years where no data is provided, the value of the most recent year is used with no escalation. The results are shown in Table 2.
The final step is to calculate the Estimated Cost for Year X using the equation given above and the Lx, E,, and Bx values. The estimated cost is given in Table 2.

Mellon Bank Pittsburgh, Pennsylvania.
Since the report dated March 23, 2005, filed with the Nuclear Regulatory Commission on Funding for CNP, Units 1 and 2, there have been no substantive changes made in the trust agreement.
