Initial Readiness Assessment Observations on draft PSAR Section 5.2 (Phase
- 6) - draft Clinch River CP application Attachments:
Initial Observations PSAR Section 5.2_Readiness Assessment_Phase 6.pdf Good Morning, Attached are initial NRC staff observations on draft PSAR Section 5.2 of Chapter 5 Reactor Coolant System and Connected Systems, that staff viewed in TVAs electronic reading room as part of Phase 6 of the Readiness Assessment of the draft Clinch River CP application.
After all six phases of the Readiness Assessment are completed, NRC will transmit, via letter, a compilation of all final Readiness Observations on the Clinch River CP PSAR chapters and sections. The nomenclature initial is being used to account for potential TVA updates to the PSAR before the end of the Readiness Assessment.
If TVA makes any future updates to the draft PSAR chapters and sections for follow up observations by NRC staff, please contact me, Greg Cranston or Sean Gallagher.
- Thanks, Allen H. Fetter, Senior Project Manager U.S. Nuclear Regulatory Commission Office of Nuclear Reactor Regulation Division of New and Renewed Licenses New Reactor Licensing and Infrastructure Branch Washington, D.C.
