In Reference 1, Indiana Michigan Power Company (I&M), the licensee for Donald C. Cook Nuclear Plant (CNP) Units 1 and 2, submitted a repair notification to the United States Environmental Protection Agency (EPA) in accordance with 40 CFR Part 82.166(n)(1).
In Reference 2, I&M, submitted a request for additional time for retrofit/retirement to the United States EPA in accordance with 40 CFR Part 82.156(i)(7)(i).
As described in Reference 1, due to an error in the scheduling process a chiller equipment repair discovered on July 9, 2012, was extended beyond the required 30 day repair limit. It was discovered on January 15, 2013, that the repairs had not been made. A refrigerant leak located at the liquid line solenoid valve and three unloader solenoid valves occurred at the leak rate of 109 pounds per year, the maximum allowable leak rate for this chiller is 35 pounds per year. As a corrective measure, this chiller was removed from service and evacuated on January 18, 2013, with an estimated repair and return to service date of February 25, 2013. In addition, a retrofit/retirement of the entire system was to be completed by August 2013.
In Reference 2, I&M has requested to extend the completion of this retrofit/retirement to October 2013.
Copies of the notifications are enclosed in accordance with CNP's Environmental Technical Specification, Part II-Nonradiological Environmental Protection Plan, Section 5.4.2.

Dear Sir or Madam:
Pursuant to 40 CFR Part 82.166.n (1),
we are providing you with an initial report regarding why more than 30 days are needed to complete an appliance repair.
Due to a scheduling error, the equipment repair due date was extended to beyond the required 30 day limit.
Identification of facility:
Cook Nuclear Plant located in Be rrien County, Lake
- Township, Bridgman, Michigan.
The leak rate was calculated to he 1.09 K per year.
The method used to calculate leak rate is as follows:
Leak rate po.nd.111ds of refrigeranit added,
365 dt Ja,'.,,"ar O
(% pr yeea) pounds of refrigerant s.horer of: # days since In fiull charge refrigerant ILat added or 365 days System manufacturer's determination of correct full charge was used to.determine full charge.
The leak rate above the trigger point was discovered on 7/9/2012.
The maximum allowable leak rate for this chiller is 35 pounds per year.
The leak locations were the liquid line solenoid valve and three of the unloader solenoid valves.
Any repair work that has already been completed; and the date when that work was completed:
Due to error in the scheduling process, the job was moved out beyond the required 30 day period and the repairs were not performed.
On 1/15/2013, it was discovered that the repairs had not yet been made.
The affected appliance was removed from service and evacuated (mothballed) on 1/18/2013, with an estimated repair and return to service date of 2/25/2013.

Due to nuclear safety requirements placed on this system, a minimum of 6 operable compressors are needed at this time.
Based on the current schedule, the estimated completion date for the entire retrofit/retirement project is August 8, 2013.

The affected appliance was removed from service (mothballed) and evacuated on 1/18/2013, with an estimated repair and return to service date of 2/25/2013.
Replacement work continues on the system.
Two of the ten chillers have been staged for replacement.
In our original request dated January 22, 2013 we stated that the retrofit/retirement project would be completed on August 8,
USEPA January 31, 2013 Page 2 2013.
Due to Nuclear Regulatory Commission safety requirements, we are working to ensure adequate back up chillers are available to the system during the replacement process.
The remaining eight chillers are on schedule to be completed prior to the upcoming refueling outage in October 2013.
Each Compressor in the new system uses 46.3 pounds of refrigerant R404A, which is a
substitute to R502 with a lower ozone -depleting potential.
