CLEAN, SAFE, AND SCALABLE BASELOAD ENERGY.

Blykalla is developing and building small modular reactors to deliver the next
generation of clean energy. We take leading research to industrialization
through our Swedish Advanced Lead Reactor (SEALER).

BUILDING THE NEXT GENERATION OF BASELOAD POWER

Blykalla is a Swedish producer of advanced small modular reactors (SMRs). Our
design is based on 25+ years of research, which we are now taking to market. A
perfect complement to intermittent energy sources, our goal is to provide the
baseload energy necessary to enable a full transition to a fossil free future.

We are currently working together with global utilities and partners to deliver
Sweden’s next nuclear reactor, with planned criticality by 2029.

A JOURNEY TOWARD
CLEAN ENERGY


FISSION AS A CLEAN SOURCE OF ENERGY

The transition to a sustainable future is dependent on carbon-free, reliable,
and affordable energy. As the world is moving toward electrification, we need
clean energy to power it. This energy has to be available where and when it's
needed - complementing intermittent sources - and accommodate a vastly increased
global energy demand.

There is an urgent need to invest in clean and stable energy capacity. Global
electricity generation is expected to grow by 65% in the next 30 years. This
will require an output of more than 40 000 TWh, compared to today's ∼25 000 TWh.
In Sweden alone, the expected electricity usage far surpasses the expected
production, pointing to an electricity gap of more than 200 TWh in 2050.


BENEFITS OF SMALL AND MODULAR REACTORS

SMRs are nuclear fission power plants that typically produce 10-100 MW per unit.
Their smaller size and output makes them suitable for serial, standardized
production, and enables more predictable production and factory based quality
controls. It also makes them suitable for decarbonizing hard-to-abate sectors
beyond electricity, such as industrial process of heat, clean hydrogen
production, and water desalination.
‍
As a result of the modular structure, construction costs are reduced by up to
60% and construction time by roughly 70%, compared to that of traditional
large-scale Generation III plants. This reduces financing risk and improves
overall project affordability, which historically has been a challenge with
nuclear power plants.

SMRs are suitable for remote and flexible deployment. Unlike traditional
generation III nuclear power, the deployment of SMRs is not dependent on close
proximity to large water areas for cooling, and reactor modules may be added or
disconnected over time to better match demand.


USING LEAD AS A COOLANT

Using lead as a coolant has a number of intrinsic advantages. For example, lead
cools the system and simultaneously ensures that radioactive elements are
retained. It has a boiling temperature of 1700°C, so there is no risk of losing
the coolant. The high boiling temperature enables a low pressure system, hence
there are no safety issues deriving from loss of pressure.

Blykalla’s reactors are passively safe, which means that no supply of
electricity, other means of power nor human action is required for emergency
cooling of residual heat. The reactor has a self-cooling function that relies on
the natural convection of lead for removal of decay heat, and its intrinsic
radiation shielding makes it possible to replace large concrete walls with the
coolant itself.
‍
We can therefore achieve passive safety in its most compact form. This
facilitates serial factory production, and has important benefits in terms of
safety and system simplifications.


TECHNOLOGY

Blykalla is building a first of a kind lead-cooled SMR concept, using a
combination of proven technology and proprietary materials.

By developing a patented, aluminum alloyed steel exhibiting perfect corrosion
resistance, we solved the number one challenge with using lead as a coolant in
nuclear reactors.

ABOUT BLYKALLA

Blykalla AB was founded in 2013 as a spin-off from the Royal Institute of
Technology in Stockholm, Sweden, where our founders have carried out research on
lead-cooled reactor systems since 1996. Since then, we have secured several
patents and investments, developed and demonstrated our technology, and
partnered with relevant industry players.
