* S. Lies, Indiana Michigan Power Company, to U. S. Nuclear Regulatory Commission, "Donald C. Cook Nuclear Plant Unit 1 and Unit 2, License Amendment Request Regarding Revision to the Emergency Plan For Technical Support Center Relocation," dated November 7, 2017, Agencywide Documents Access and Management System Accession No. ML17317A454.
By Reference 1, Indiana Michigan Power Compa*ny (l&M), the licensee for Donald C. Cook Nuclear Plant (CNP) Unit 1 and. Unit 2*, submitted a request for Nuclear Regulatory Commission (NRC) review and approval of a revisiordo the CNP Emergency Plan for Unit 1 and Unit 2. The proposed revision would move the Techni_cal Support Center (TSC) to a different location in a new facility.
When Reference 1 was submitted to the NRG, it did not include the dose calculation that demonstrates the habitability of the new TSC. Reference 1 stated that upon l&M approval of the dose calculation, that it would be.submitted to the NRG as a supplement to Reference 1. This letter
* submits the new TSC dose calculation as a supplement to Reference 1.
By Enclosure 2 to Reference* 1, ,1&M previously provided key input assumptions for the new TSC dose calculation. One of these input assumptions was that the TSC ventilation would be placed in the_ emergency mode of operation within 20 minutes of the start of a loss of coolant accident. The time to place the TSC ventilation in emergency mode was moved from being a key input assumption, of 20 minutes, to being a limitation, of 53 minutes, of the calculation**and is discussed in the Introduction and.in Section 6 of Enclosure 2. The resulting dose that would be received by*
any TSC occupant would remain below the limit of 5 rem in 30 days.
Enclosure* 1 to this letter provides an affirmation statement pertaining to the information contained            I herein. Enclosure 2 provides the radiological *analysis-for the new TSC.           *          ..
