Hadid SUBKI, Technical Head of the SMR Program at the International Atomic Energy Agency (IAEA) explained the needs for SMR development and the different designs of reactors. Then he showed to participants the interest of using SMR for grid-stabilization, for strengthen power grids or for the areas with small needs in electricity.

4. Use of SMRs for electricity grid-stabilization
• In the EU:
• large power markets & well interconnected grid
• large power additions/subtractions could cause grid instabilities.
• future systems will have increasing shares of renewable energy sources
(mainly wind power) that will affect the electrical grid operation and require a
different and more flexible back-up approach.
• Most SMR concepts intended for generating base-load power; however
innovative concept can be operated in a load-following
• Some new concepts will have enhanced load follow capability
• If SMRs cost competitive with clean coal & natural gas, they could be
used as peak and back-up power units.
• The EU and some countries also studying a “smart grid” and energy
storage systems
• Allow greater use of decentralized sources of renewable energy which would
also enable economic operation of nuclear reactors producing base-load
electricity.

17. Issues of Integrating SMR + Cogeneration + Wind
Source: J. Carlsson, D. Shropshire, EC – JRC, 2011
• Challenge in finding the optimal ratio of the wind
farm capacity to nuclear capacity, while providing
adequate heat to support biomass processing
while matching power demands
• Variability of power to grid relative to instantaneous
demand should be minimized
• If nuclear is sized too large, variability of power
production may be reduced, however, process
heat and electricity are wasted
• Biomass availability is a key constraint

SMR deployment
• The need to develop legal and institutional frameworks, particularly for

•

•
•
deployment in foreign market;
Lack of human resource, skills and capacity, limited operating
experience in advanced SMRs;
Public acceptance, lack of persistent support from governments, and no
laws and regulations for both NPP and SMR in new entrants;
The need to assure that SMR regulatory framework is applied
commensurate with attended risk, so deployment can be accomplished
in a cost-effective manner and competitive with alternative energies;
Long lead-time to prepare for and receive regulatory review;
The need to get sufficient regulatory credit for inherent safety and
security in the design;
For SMR with innovative features: review code & standards that impact
licensing. Could take 2 – 5 years to develop and approve revisions.
Embarking countries lack of infrastructure and HR to conduct
technology assessment and R&D for HR development;

26. Summary
• Studies needed to evaluate the potential benefits of deploying SMRs in
•
•
•
•
grid systems that contain large shares of renewable energy.
Studies needed to assess SMR “target costs” in future cogeneration
markets, the benefits from coupling SMRs with wind turbines to
stabilize the power grid, and impacts on sustainability measures from
deployment.
There are technical challenges in integrating nuclear with RES,
however “no solution that allows significant increases to
renewable energy penetration in the grid will be simple”
SMR is an attractive option to enhance energy supply security in
newcomer countries with small grids and less-developed
infrastructure and in advanced countries requiring power supplies in
remote areas and/or specific purpose;
Innovative SMR concepts have common technology development
challenges, including regulatory and licensing frameworks
