Meeting Obiective Support NRC efforts to review and approve the Indian Point Unit 2 Stretch Power Uprate LAR - prior to power ascension from 2R1 6.
- Enterey Project Objectives
- Safely implement a 3.26% increase in the licensed core thermal power from 3114.4 MWt to 3216 MWt at IP2 for the start of CY17 in November 2004.
- Support Entergy's strategy of providing additional electricity to the Northeast Region.
- Maintain and enhance the integrity of the IP2 plant design basis.
-Entergy 2
Project Overview Key Perspectives
- Small "Stretch" increase of 3.26% to 3216 MWt.
- SPU will be no greater than the original Engineered Safeguards Design Rating (ESDR).
- "Defense in Depth" approach to quality.
- Design and licensing bases acceptance criteria continue to be met for IP2 systems, components, and safety analyses.
- No Significant Hazards per IOCFR50.92.
