Nuclear Power is a Key Element of Our Energy Mix
In order to meet the planet’s ever expanding need for affordable energy, a number of different types of clean, emission-free technologies must be developed and employed. Nuclear power, with its ability to provide ro- bust, continuous, and reliable energy – regardless of weather conditions – must be part of this diverse mix. However, conventional large nuclear power plants, due to construction expense and the time required to build them, must be augmented with a smaller solution.

Small & Modular nuclear power Reactors (SMRs)
That “smaller solution” is the category of power reactors known as Small & Modular nuclear power Reactors (SMRs). The history of SMRs is about as long as the commercial use of large nuclear power plants. The fuels and technology included in today’s SMR designs have been studied for over 50 years, and some units went online decades ago. SMRs provide the benefits of larger nuclear power plants – clean, continuous, reliable energy with no greenhouse gas emissions – yet they require very little space in which to operate. SMRs can be transported to sites and engaged
without the transportation and construction costs of big nuclear power plants. Sealed and self-contained, they offer a safe energy solution for areas of the globe where nuclear proliferation is a concern. But unlike any other clean energy generation, SMRs operate when the wind doesn’t blow and the sun doesn’t shine.

The Hyperion Power Module (HPM)
The Hyperion Power Module (HPM) is the frontrunner in the SMR industry. The HPM is one of the smallest, safest, and simplest designs. Hyperion Power is deeply concerned about the state of the environment, needless human suffering, and the search for energy independence – vital not just to the U.S., but to every nation on the planet. Hyperion Power believes that these concerns can be met through the safe deployment of SMRs and so is dedicated to realizing the full potential of this small but mighty power module – the HPM. Clean, safe, affordable energy should be available to everyone – even in the most remote locations.
Industry & Community Benefits
The Hyperion Power Module (HPM) offers a perfect “distributed” independent energy solution for remote locations that are too difficult or expensive to reach with traditional electrical grid systems from one large, centrally-located power plant. Each HPM-based electric plant generates 25MW of electricity and can be configured for steam only, co-generation, or electricity only.

An HPM-based power plant can supply enough power for:
  • 20,000+ American-style homes, or a …
  • Large hospital complex
  • Entire government complex
  • Irrigation systems
  • Water treatment & distribution site
  • Waste – sewage facility
  • Heavy oil recovery
  • Refugee community
  • Emergency – disaster response center
  • Military installation
  • University or college
  • Mining or drilling operation
  • Industrial center or factory
  • Corporate data centers
  • And more …
  • HPM power plants can also be “teamed” in groups of two or more to provide additional power. By teaming multiple units, a medium to large-size power plant can be constructed years faster than a plant constructed on site in the traditional manner.

    Hyperion Power Module Product Characteristics
    1. Transportable
  • Unit will measure approximately 1.5m wide x 2.5m tall
  • Fits into a standard fuel transport container
  • Transported via ship, rail, or truck
  • Modular design for easy and safe transport
  • 2. Sealed Core – Safe and Secure
  • Factory sealed; no in-field refueling, closed fuel cycle
  • Returned to the factory for fuel and waste disposition
  • 3. Safety
  • System will handle any accident through a combination of inherent and engineered features
  • Inherent negative feedback keeps the reactor stable and operating at a constant temperature
  • Sited underground, out of sight
  • Proliferation-resistant; never opened once installed
  • 4. Operational Simplicity
  • Operation limited to reactivity adjustments to maintain constant temperature output of 500C
  • Produces power for 8 to 10 years depending on use
  • 5. Minimal In-Core Mechanical Components
  • Operational reliability is greatly enhanced by the reduction of moving mechanical parts
  • 6. Isolated Power Production
  • Electric generation components requiring maintenance are completely separated from the reactor
  • Allows existing generation facilities to be retrofitted
  • The Hyperion Power Module will be licensed by national and international regulatory authorities.
