1. Letter from J. P. Gebbie, Indiana Michigan Power Company (l&M), to U. S. Nuclear Regulatory Commission (NRC) Document Control Desk, "Donald C. Cook Nuclear Plant, Units 1 and 2, License Amendment Request to Adopt TSTF-490, Revision 0, "Deietion of E Bar Definition and Revision to Reactor Coolant System Specific Activity Technical Specification" and Implement Full-Scope Alternative Source Term, dated November 14, 2014, Agencywide Documents Access and Management System Accession Number ML14324A209.

By Reference 1, Indiana Michigan Power Company (l&M), the licensee for Donald C. Cook Nuclear Plant Unit 1 and Unit 2, requested a license amendment to adopt Technical Specifications Task Force (TSTF)-490 and implement full-scope alternative source term. As a result of discussion between l&M and U. S. Nuclear Regulatory Commission staff, it was determined that a supplement to Reference 1 was needed to clarify the definition of Dose Equivalent Xenon (Xe)-133, as described in TSTF-490.

This letter provides the supplemental information. Enclosure 1 to this letter provides an affirmation statement pertaining to the information contained herein. Enclosure 2 contains the revised mark-up for the Unit 1 Technical Specifications (TS) 1.1 definition of Dose Equivalent Xe-133 and contains the revised mark-up for the Unit 2 TS 1.1 definition of Dose Equivalent Xe-133.

The conclusions reached in the original determination that this License Amendment Request contains No Significant Hazards Considerations and the basis for the categorical exclusion from performing an Environmental Impact Statement have not changed as a result of this supplement.

U.S. Nuclear Regulatory Commission AEP-NRC-2016-78 Page 2 There are no new regulatory commitments made in this letter. Should you have any questions, please contact Mr. Michael K. Scarpello, Regulatory Affairs Manager, at (269) 466-2649.

Definitions 1.1 1.1 Definitions DOSE EQUIVALENT XE-133 DOSE EQUIVALENT XE-133 shall be that concentration of Xe-133 (microcuries per gram) that alone would produce the same acute dose to the whole body as the combined activities of noble gas nuclides Kr-85m, Kr-85, Kr-87, Kr-88.

Xe-131m. Xe-133m, Xe-133, Xe-135m. Xe-135, and Xe-138 actually present. If a specific noble gas nuclide is not detected. it should be assumed to be present at the minimum detectable activity. The determination of DOSE EQUIVALENT XE-133 shall be performed using effective dose conversion factors for air submersion listed in Table 111.1 of EPA Federal Guidance Report No. 12, 1993, "External Exposure to Radionuclides in Air. Water. and Soil."

E AVERAGE E shall be the average ('.veighted in proportion to the DISINTEGRATION ENERGY concentration of each radionuclide in the reactor coolant at the time of sampling) of the sum of the average beta and gamma energies per disintegration (in MeV) for isotopes, other than iodines, 'Nith half lives > 15 minutes, making up at least 95% of the total noniodine activity in the coolant.
