LEADING THROUGH OPERATING PLANT SUPPORT
Support overall reliable plant operation
Safer, Shorter and More Efficient Outages
Maximize power output
Apply global lessons learned and best practices
Sustain technology innovation
EXAMPLES:
Spent Nuclear Fuel Solutions
Transference of commercial spent nuclear fuel from spent fuel pools to a dry cask storage system.
From complete canister loading and transfer campaign to niche services such as fuel-handling operations and canister-closure welding.
Remote, orbital machine welding and field machining
Passive safety systems
Desirable enhanced safety features.
Systems that function without operator action or active power in order to ensure plant safety in the event of a particular type of emergency, such as loss of coolant or loss of coolant flow
Example: Dry filter method (DFM) - filtered containment venting system
LEADING THROUGH PLANT LIFE EXTENSION
Extension Solutions Beyond 60-year License Renewal Rule
With increasing carbon restrictions and growing demand for electricity, reliable, carbon-free baseload electricity generation is more important than ever.
Because of long lead times for new nuclear installations, we must look to our current nuclear operating fleet, which has been providing energy safely for decades, to meet energy demands while also considering how additional nuclear plants can bolster future nuclear energy supply.
Planned evolutions - needed to evaluate and management component repairs, replacements and upgrades:
Continued safety focus
Operational and economic efficiency
Regulatory governing
Examples:
Concrete robustness
Electrical and cable systems
Buried equipment issues

LEADING THROUGH COMPLETE LIFE-CYCLE SUPPORT
Decommissioning, Dismantling and Remediation
Waste Management
Overview:
Nuclear facilities no longer operating due to economic factors, licensing issues, end-of-life components or other reasons are candidates for decommissioning and dismantling, followed by site restoration.
Decommissioning business is not a negative. It is a recognition of a manageable part of a plant’s life cycle.
Business opportunity that includes job growth. Also way to develop new tooling and technology for use in new units and operating plants.
Obligation to our industry to fulfill our promise to return the plant’s land used during service life; show overall positive environmental impact.
Part of the mystique about nuclear power is that it is widely believed that plant sites will be a forever wasteland, which is completely untrue. We as an industry have to eliminate that fear and show how we can return the land to useable property to gain support for new build.
Stages:
Initial planning Dismantling
Defueling Waste management
Inventory & Characterization Demolition
Decontamination Site clearance
Westinghouse Experience and Future
50+ years of global nuclear industry leadership with clients in France, Italy, the U.K., and the United States
Investing in DD&R and WM innovation programs to address future market needs
Serving gas- and sodium-cooled reactors, and pressurized and boiling water reactors.
Treatment and handling of radioactive waste
Interim storage and final disposal of low-, intermediate- and high-level waste
LEADING THROUGH INNOVATION
Advanced tooling, technology and processes to reduce outage durations, dose and costs through flawless execution
EXAMPLES:
(pic ALS platform chasis) Advanced Logic System (ALS)
(pic—standard SG set-up) Reduce steam generator inspection times; processes for steam generator, refueling and reactor disassembly on PWRs and BWRs
Mention outperforming leak-free BWR fuel
