What is U-Battery?
• A source of heat and
electricity installed at the
point of use – embedded
power
• For end users, it provides
a solution to their Energy
Trilemma
U-Battery: Technology and Fuel
• Reactor Building footprint projected to be equivalent
to penalty area on soccer pitch.
• TRISO fuel was first developed in the UK and has a
long and successful history of development and
deployment. Discussions have taken place with
several international vendors including BWXT. TRISO
fuel provides damage resistance to temperatures of
1600˚C – well above worse case scenarios.
• This fuel type is at a high level of Technology
Readiness and underpins our safety case.3
• High Temperature Gas Reactor technology, with each
reactor rated at 10MW(th) & 4MW(e).
• Nearly 20% U-235 enriched accident tolerant TRISO
fuel, embedded within Prismatic Block type fuel.
• Helium primary coolant transferring heat via
intermediate heat exchanger to a nitrogen Closed
Brayton Cycle secondary.
• Reactor outlet temperature of 750˚C.
• Cycle efficiency of >40% when producing electricity
through gas turbine-alternator.

Technical and Cost Development
• Overall U-Battery Conceptual Design
Review– Design updates to find and use existing transport flask,
Excellox not possible
– Review decision between BeO and graphite moderator
– Two single units or a twin reactor unit using a single
turbine/generator
• Product Breakdown Structure Delivered
• Cost Estimate Model Developed– Atkins/Faithful and Gould Cost Estimators
• Major Component Conceptual Design
Delivered– Reactor Pressure Vessel
– Intermediate Heat Exchanger
• Interaction with partners and Tier 1
supply chain to deliver cost estimate

The markets and applications vary by country.
• In UK and many other countries, the market is
for embedded generation at industrial sites.
Many sites can make use of the cogeneration
capability. Such deployment avoids significant
grid connection costs.
• In Canada, there are many remote
communities that are not connected to a
national grid currently operating diesel
generators. This is true, also, for many islands
and parts of the developing world where it
would obviate the need to build a national grid.
• In the nuclear industry, U-Batteries could be
always-on emergency generators for large
nuclear power plants.
• Desalination is a further application.
• Deployment at military sites may be attractive
Projected Markets
International Interest

Poland
• Letter of Intent to investigate early deployment at
NCBJ site, near Warsaw
• Potential for Polish, EU structural and Euratom/EIB
funding
US
• Presented at US Nuclear Infrastructure
Conference in Oak Ridge Feb 2016
• Advanced Research Projects Agency – Energy
• NRC has initiated a programme to consider
licensing for non-LWRsJapan
• Interest of JAEA to bring expertise derived from HTTR.
• NDA signed.
Canada
• Ontario Energy Ministry/Natural Resources Canada
study executed by Hatch. In top 9/100. Study
recommended direct engagement.
• Interest in early deployment at Chalk River
UK/URENCO
• URENCO £4m for Phase 1
• Partners “sweat” equity
• Seeking matched funding from Govt.
• DECC SMR TEA and micro-reactor study
• DECC SMR Competition
Funding
• Phase 1– URENCO £4m
– Partner “sweat equity”
– Matched funding sought from UK Govt.
– Potential new partners and/or from international interest
• Phase 2 and beyond– URENCO to continue assuming that we pass stage-gates
– Partners have the same choice
– Further partners may join
– UK Govt, EU or other international development funding is possible
– Both Rothschild and PWC have indicated that equity and debt funding
will be possible at this stage.

Summary and Conclusion
• Technology is deliverable – Development not Research.
• The market for micro-reactors is there.
• Licensing needs to be target-based, as in UK, Canada etc. NRC has seen a need to
review its processes acknowledging that its current licensing was created for large
LWRs
• Financing is simpler than large reactors because the capital cost is lower and the
construction period is much shorter.
• Much of the competition is with diesel or CCGT so the business model foresees an
organisation that allows customers to buy power - a utility. It foresees an
organisation that will maintain and re-fuel U-Batteries.
• We have a strong team and we are delivering
