The following are examples of process heat applications for IMSR:
Demands for safe, secure supplies of
potable water globally are increasing
faster than can be provided by natural,
ever-depleting sources of fresh water.
Simultaneously, global demand for
electricity is also projected to grow significantly.
Desalination of seawater and brackish water is extremely energy intensive. The IMSR is uniquely suited to
provide clean, heat energy and electric
power on an industrial scale needed at
cost-competitive prices to enable far
greater deployment of desalination
In addition to utilizing heat energy
for desalination, hot industrial salts
can be directed to a hot salt mass en-
ergy storage, a method that is already
the IMSR; however, with future
iterations of IMSR technology, the
IMSR is very capable of using a di-
verse array of fuel forms, includ-
ing thorium-based fuels and spent
nuclear fuels from existing nuclear
• An IMSR power plant can rapidly
load follow grid power demand.
• An IMSR power plant is anticipated to deliver power at less than
$50 per MWh, which is highly
competitive with fossil fuel combustion.
This type of high temperature re-
actor allows for much more than just
electricity production. An IMSR power
plant can deliver 600C heat by liquid
salt up to 5 kilometers to an industri-
al energy park. This allows the IMSR
baseload heat production of nuclear to
be switched from electric power pro-
vision to the production of the most
valuable high energy products in off-
peak hours. This maximizes use of
IMSR heat energy and allows the IMSR

• The reactor core contains a graphite moderator – outside of the
moderated area, the salt is no longer active.
• A secondary heat exchanger exchanges heat via secondary salt to
a third loop containing a 600C industrial salt that can be transported up to 5 kilometers.
• The IMSR has a low level of tritium production. Furthermore, the
IMSR’s three successive isolation
loops further ensures no tritium
moves beyond the nuclear island.
• Uranium enriched to less than
5% is currently intended to fuel
he primary components (pumps,
ator and primary HX) of the reactor
e sealed in a compact and replace-omponent - the IMSR Core-unit.
