SMR-160 Delivers High Performance with a Smaller Footprint

The major features of SMR-160 include its small footprint (4.5 acres), minuscule site boundary dose, large inventory of coolant in the reactor vessel and its modularity – allowing project owners the freedom to effectively build the number of units to meet current and future demand. Small physical plant size and the reduced scope of equipment and systems means a reduction in capital investment as well as security and maintenance costs.

Minimal Operation & Maintenance Cost (O&M)

SMR-160’s innovative design features reduce the burden for operations to achieve safety, reliability, and availability goals. The following features of SMR-160 significantly reduce O&M cost:

  • 80 Years service life.
  • On-site underground storage of used fuel for 100 years of operation.
  • SMR-160 is a completely autonomous design.
  • Operating without boron in the primary coolant; reducing the corrosion and radioactive waste issues associated with borated reactor systems.
  • The primary system is based on natural convection eliminating the reactor coolant pumps and all of the associated components necessary to make them operate reliably.
  • The steam generator provides superheated dry steam to avoid additional components and to preserve turbine blade life.
  • All ASME welds in safety-related systems, structures, and components are located with inspectability in mind so that In-Service Inspection can be readily performed.
  • The Containment, made of ductile ribbed steel, is further buttressed by a Containment Enclosure Structure also engineered to withstand a crashing aircraft. In addition the fuel pool has its own missile protection structure.
  • SMR-160 uses state-of-the-art automated data collection and diagnostic tools to minimize labor needs.

The operational simplicity and modest outlay required to commission and operate SMR-160 will make it an ideal solution to deliver pollution-free nuclear energy to developing countries, help expand reliable and affordable supplies of energy to developed nations and sustain economic growth worldwide.

Short Construction Life-cycle

After the licensing process is completed and the first unit is built (to help streamline the construction process), the time from “the first shovel in the ground to the completion of erection” is expected to be less than 36 months.

The short construction life-cycle is possible because all plant components are shop fabricated, easily transportable and site assembled. This means reduced lead times, assured delivery of high quality products and reduction in cost.
