Small Modular Reactors: Progress Towards Deployment


• Accelerate transition to cleaner energy industry

Balance intermittent sources with nuclear … load following

Repower aging fossil sites … 45GW < 500 MWe

Replace retiring nuclear plants … economics

• Expand practical opportunities for nuclear power

Access for deregulated, merchant, and smaller utilities

More flexible siting

Incremental power additions

The Nuclear Industry Challenge


• Smaller plant, smaller investment

• Integrated reactor system

• Simpler, safer, architecture

• Factory built

• Lower risk

B&W mPower™ Integral Reactor

Traditional 2 Loop PWR NSSS

Same proven technology – better architecture

Reactor Coolant Pumps (4)

Reactor Vessel

Pressurizer

What is a Small Modular Reactor (SMR)?


B&W mPower Nuclear Island Features

• 2 x 180MWe units

• Fully underground reactor systems

• Optimized for minimum staff and O&M

• Enhanced spent fuel pool cooling

180MW mPower SMR

• Compact <40-acre site footprint

• Integral, rail-shippable reactor module

• Passively safe design philosophy

• 4-Year extended operating cycle

mPower “twin-pack” Site Layout

Simple and robust architecture lowers cost / risk, enhances licensing

Enables EPZ “inside the fence”

• Core protected for all postulated accidents

• Two weeks before any fuel damage after most severe hypothetical accidents


Testing is foundation for low risk, high reliability mPower design

Developing a Stable and Sustainable Supply Chain

• Revitalizing entire nuclear supply chain

• Working with more than 200 suppliers across 33 states

• Suppliers selected for major equipment

• B&W only US manufacturer capable of producing entire reactor

Robust supply chain will create skilled, and desirable jobs in engineering, manufacturing and construction

SMR Impact on Job Creation

SMRs can have a significant impact on job creation

Phase Direct Jobs* Design & Licensing (2008-2017) 400 Mfging, Constr., Launch 2 unit Clinch River Plant 1,600 Annual Operation of 2 unit Clinch River Plant 300-350 Mfging, Constr., Launch of each 2 unit NOAK Plant 1,360 Annual Operation of each 2 unit NOAK Plant 300-350 *Estimates do not include significant supplier base job creation.

NOAK = Nth of a kind


• Extend RPS / Clean Energy technology policies to SMRs

Only practical, near-term carbon-free base-load energy source

Lower total cost of electricity than wind or solar technology

• Enhanced PPA and PTC regulatory framework

Creates opportunity for Municipals and Cooperatives

Acknowledges long service life of investment (60-80 years)

• “Early adopter” incentives

Energy independence

Portfolio balancing

SMR Legislative and Policy Enablers

SMR will compete on a “level playing field”


Changing the game … mPower’s Vision

• A “differentiated” nuclear solution

• Changing traditional rules of the game

True modular construction

Right-sized Emergency Planning Zone

Design for optimum security staffing

Extended 4-year operating cycle

Load following opposite wind/solar

Improve the economics .. .reduce the investment risk
