Plant Vogtle Leads the Next Nuclear Generation
In August 2009, the Nuclear Regulatory Commission (NRC) issued its fourth Early Site Permit for two new units at Southern Nuclear’s Vogtle site and its first for the Westinghouse AP1000 pressurized water reactor design. The two new units planned for Vogtle also became the reference plant for the AP1000 under NuStart in June 2009. This means Vogtle Units 3 and 4 will be the first licensed installations of the new AP1000 reactor design in the U.S. Plant Vogtle is expected to get the NRC’s approval to begin construction in 2011.

Modularizing Containment Vessels in New Nuclear Power Plants
Using modularization in the construction of nuclear containment vessels can be one way to control both cost and schedule when building the next generation of U.S. nuclear power plants. Although the advantages of modularization can be significant, each new reactor design and plant site poses unique construction challenges and must be individually analyzed to determine the benefits of this approach.

Catching Faults with Centralized Condition Monitoring
In 2007, Exelon Corp. began the Centralized Performance Monitoring (CPM) pilot program. The goal was to reduce downtime costs and lost revenue associated with the 25% of unplanned forced losses across its fleet of 17 nuclear power units without additionally taxing existing personnel or adding new personnel.

HDPE Replaces Carbon Steel in Safety-Related Pipe System
Corrosion of steel water pipes in the safety-related piping systems of aging U.S. nuclear power plants is fast becoming a safety concern and a significant operational cost, not to mention an indication of potential future liability for nuclear utilities currently constructing new plants or retrofitting existing sites.
