Introducing the Synchrotron Fusion Reactor by Fusion Harmony!
...A new way to solve the commercial fusion energy problem.
The Synchrotron Fusion Reactor (SFR) is the culmination of Professor
Emeritus Hironari Yamada's life work in advanced particle and
accelerator physics. The SFR is a completely new approach to
the realization of commercial fusion energy through the deployment of a
carefully modified, tuned, and operated electron particle accelerator known as MIRRORCLE.
MIRRORCLE is a desktop sized circular accelerator and its many unique operating principles made
it the is the world first operating tabletop synchrotron. MIRRORCLE Technology
was first realized as a functioning desktop synchrotron in the
early 2000s, and has since been manufactured in a number of sizes
and application specific configurations. Commercial collaborations resulted in
the creation of the MIRRORCLE Analysis Center, and as a consequence MIRRORCLE
desktop synchrotrons now have a collective accumulation of two
decades of research and operation. The stability and maturity of MIRRORCLE
technology has made it the ideal platform to implement the SFR.
The SFR is NOT based on chasing extended extrapolations of idealized nuclear fusion theory, but rather
an interpolation of the many real life observed states of the MIRRORCLE platform seen over
decades.
Fusion Harmony was formed by Professor Emeritus Hironari Yamada for the purposes of
commercializing the SFR and making fusion power available to everyone. Fusion Harmony is now
a small group of people with business, science and engineering skills ready to build
the first SFR based on the MIRRORCLE-20sx platform.
...The Synchrotron Fusion Reactor comes with many inherent benefits.
- Compact size – In a deuterium–tritium configuration (D–T) a single SFR provides 20 MW of
heat energy which conservatively translates to 7 MW of electricity using the classical steam energy conversion cycle.
This is good for powering approximately 5600 American sized houses based on a daily consumption of 30 kWh. The small
module size means it is a cost effective viable power source for many small but important applications
needing reliable power that would otherwise have to continue to depend on legacy energy sources. In a
deuterium–deuterium (D–D) configuration the SFR produces only 5.5 MW, but the fuel cycle is greatly simplified.
Deuterium is not radioactive and is also readily available.
- Modularity – Multiple SFRs can be combined as required to create larger power sources yet still maintain
financial viability. Conversely multiple SFRs can work independently as a distributed power source.
- Reliability – Built on a known reliable platform using already existing and well understood technology. This immediately breeds confidence that the SFR is not just another fancy laboratory exercise, but a ready to use commercially viable product. Maintenance, service, support and spare parts are all well understood entities.
- Financial viability – A key point with SFR development was that it is a new clean power source but not an exotic power source. A prime objective of the SFR was that it must meet the demands of market
based systems where it would compete with alternatives, both new and legacy energy sources.
- Physical simplicity – Fusion as a power source has been tackled for decades to little avail.
Fusion engineering is complicated, but basic fusion theory is less so. SFR exploits various fundamental aspects of
fusion theory in a unique operating environment to bypass the typical fusion approach using 100 million degree
temperature plasma contained in a Tokamak (magnetic containment) or inertial containment device. Naturally any man made device operating at 100 million degree presents vast engineering/operational challenges and complexities.
In contrast the picture to the left shows the bulk of a MIRRORCLE-20sx installation, the existing product platform
to implement the SFR. The 1.3 meter ring to the left is the electron beam generator MICROTRON, on the right side in
vertical orientation is the desktop synchrotron ring MIRRORCLE-20sx. Together they form the basis of MIRRORCLE technology.
- Operational simplicity – Most current fusion power source prospects leading the charge
towards commercialization employ high temperature plasma and are invariably large complex systems requiring
teams of people to operate and maintain them. In comparison, this makes a D–D configured SFR look more like an old
wood stove, except it is burning deuterium. Fusion happens in a near perfect vacuum conditions and power
output is easily modulated to match demand. This is fundamentally different from nuclear fission reactors which
require cooling during operation regardless of the actual power demand.
- Inherent safety – Last but certainly not least is safety. SFR operation is a symphony of
known components operating together to achieve a sustained fusion reaction. Break anything and the conditions for
fusion disappear within milliseconds. Only small amounts of power input are required for SFR operation thus this
power input reservoir can not be the source of large scale problems. This cannot be said for many other forms of
energy provisioning, both new and legacy. SFR's small size and efficient operation means regardless of what does go
wrong the problems will always remain disproportionately small. Process temperatures and pressures associated
with SFR fusion are lower than existing legacy fuel systems and not a reservoir of energy to amplify disaster
And unlike a nuclear fission reactor, the SFR operates in a near perfect vacuum making a reactor explosion
impossible.
- Nuclear waste – The SFR does not create a nuclear waste problem. Even with complete SFR site
destruction due to external reasons, a very small amount of on site tritium would be released. Being a gas of
relatively low radioactivity, it is quickly dissipated. The half life of tritium is 12.33 year so it is impossible to create long term contamination no matter what happens. The SFR is a true environmentally compatible green energy source.
...What makes the Synchrotron Fusion Reactor so different?
In short, almost everything. The long answer is far more interesting so lets explore the details.
