To actively cope with climate change, ISMR can provide cutting-edge services related to advanced small modular reactors, nuclear hydrogen, and digital twin technology. ISMR will extend the organizational learning capabilities and alter the basis of competition.
ISMR wants to be competence-enhancing, building on existing know-how and reinforcing incumbents’ positions.
Small Modular Reactors (SMRs)
ISMR is well equipped with advanced technology and global networks to deliver design and engineering services to our customers of SMR stakeholders.
Small modular reactors (SMRs) are advanced nuclear reactors that have a power capacity of up to 300 MWe per unit, which is about one-third of the generating capacity of traditional nuclear power reactors. SMRs, which can produce a large amount of low-carbon electricity, are:
- Small: physically a fraction of the size of a conventional nuclear power reactor.
- Modular: making it possible for systems and components to be factory-assembled and transported as a unit to a location for installation.
- Reactors: harnessing nuclear fission to generate heat to produce energy.
The World Nuclear Association (WNA) lists the unique features which include:
- Small power and compact architecture and usually (at least for nuclear steam supply system and associated safety systems) employment of passive concepts. Therefore there is less reliance on active safety systems and additional pumps, as well as AC power for accident mitigation.
- The compact architecture enables modularity of fabrication (in-factory), which can also facilitate the implementation of higher quality standards.
- Lower power leading to reduction of the source term as well as smaller radioactive inventory in a reactor (smaller reactors).
- Potential for sub-grade (underground or underwater) location of the reactor unit providing more protection from natural (e.g. seismic or tsunami according to the location) or man-made (e.g. aircraft impact) hazards.
- The modular design and small size lends itself to having multiple units on the same site.
- Lower requirement for access to cooling water – therefore suitable for remote regions and for specific applications such as mining or desalination.
- Ability to remove reactor module or in-situ decommissioning at the end of the lifetime.
ISMR is building the hydrogen economy as a link to the hydrogen ecosystem.
Nuclear power already produces electricity as a major energy carrier with well-known applications. Operating at very high capacity factors, nuclear energy is well placed to produce zero-carbon hydrogen as an emerging energy carrier with a wide range of applications. The evolution of nuclear energy's role in hydrogen production is seen to be:
- Cold electrolysis of water, using off-peak capacity (needs 50-55 kWh/kg).
- Low-temperature steam electrolysis, using heat and electricity from nuclear reactors.
- High-temperature steam electrolysis, using heat and electricity from nuclear reactors.
- High-temperature thermochemical production using nuclear heat.
- Use of nuclear heat to assist steam reforming of natural gas (methane).
ISMR can provide a virtual environment where process control and operational solutions are designed and tested before being applied to the live plant.
A digital twin is a software-based virtual replica of the complete physical assets of a production facility, including its process equipment, instrumentation, and controls, as well as the production processes. Through this replica, the operation of these assets is modeled and simulated through their lifecycles.
