Feedback/Questions & Answers AE:Entergy

Meeting Obj ective Support NRC efforts to review and approve the Indian Point Unit 3 Stretch Power Uprate LAR by March 2005 - prior to start of the 3R13 Refueling Outage.

Entergy

Key Perspectives

  • Licensed "Stretch" increase of 4.85% to 3216 MWt.
  • Licensed core power will be no greater than the original maximum calculated reactor power.
  • Format, content, and methodologies very similar to separate IP2 SPU submittal.
  • Incorporated IP2 SPU lessons learned and NRC Feedback.
  • Took a "Defense in Depth" approach to quality measures.
  • Design and licensing bases acceptance criteria remain the same and continue to be met for IP3 systems, components, and safety analyses.
  • No Significant Hazards per 10CFR50.92.

=Entergy

Proj ect O)j ectives

  • Safely support and implement a

/4% increase in the licensed core thermal power for IP3 at the start of Cycle 14 (Phase 1).

  • Support Entergy' s strategy of providing much-needed additional electricity to the Northeast Region, particularly Metropolitan New York City.
