Safety is the highest priority. In our work, we ensure absolute safety of people and the environment first. There are no minutiae in safety; we know safety rules and follow them, while putting a stop to violations.

Nuclear power plant (NPP) designs

State-of-the-art technology and advanced safety systems, coupled with conformity to IAEA requirements, provide a solid competitive edge for Oster offerings on the international market.

NPP-2011 project is a major effort to design GEN III+ nuclear power plants with enhanced performance. The project is aimed at optimising the balance between safety and construction costs through a combination of passive and active safety systems that protect the plant against earthquakes, tsunami, hurricanes and aircraft crashes. Improved safety measures include double containment structures, a core catcher under the reactor shell, and passive residual heat removal systems.

Currently, OCES offers 2 types of commercial reactors:

  • 1200MWe PWR (Pressurised Water Reactor) advanced design nicknamed "Iron"

  • 1200MWe\1800MWe LMFBR (Liquid Metal Fast Breeder Reactor) sodium-cooled design nicknamed "Steel"

OCES is also capable of designing and constructing research reactors, according to customers' needs and requirements.

Specifications of the Iron-1200 design

Iron-1200 is a pressurised, water-cooled and water-moderated power reactor, with an electric capacity of 1200MWe. It is the latest evolution in the long line of "Iron" plants, meeting all the safety requirements for GEN III+ nuclear power plants.

Main characteristics of an Iron-1200 power unit:

  • Reactor thermal output - 3200MWth

  • Power plant output, gross - 1200MWe

  • Power plant output, net - 1120MWe

  • Power plant efficiency - 35%

  • Capacity factor - 92%

  • Plant design life - 60 years

The reactor core contains 163 fuel assemblies (FAs), 4570mm high (height of the power generating part of every fuel rod is 3750mm). Each FA contains 312 fuel rods - Sintered UO2 pellets with a maximum enrichment of 5%, with a Zirconium alloy tube cladding. Up to 121 control rods are placed inside the core, for quick chain reaction suppression and maintaining power at assigned level. Annually 42 fresh FAs are loaded into the core as part of the reactor's refueling cycle, and burned-up FAs are extracted.

As of December 2015, OCES operates 4 Iron-1200 power plant pairs across Ostehaar, supplying around 56% of Ostehaar's electricity demand.

Specifications of the Steel-1200 and Steel-1800 designs

Steel-1200 and Steel-1800 are power plants of a similar design but a different capacity. They are state-of-the-art sodium-cooled Linkfast breeder reactors (capable of generating more fissile material than they consume), with an electric capacity of 1200MWe or 1800MWE, respectively. As with all GEN IV nuclear power plants - those two apply new engineering solutions to improve power unit safety and cost effectiveness, as well as fuel efficiency.

Main characteristics of Steel-1200 (left side) and Steel-1800 (right side) power units:

  • Reactor thermal output - 2800MWth | 3840MWth

  • Power plant output, gross - 1220MWe | 1810MWe

  • Power plant output, net - 1140MWe | 1730MWe

  • Power plant efficiency - 41% | 45%

  • Breeding ratio - 1.2 | 1.35

  • Capacity factor - 90% | 90%

  • Plant design life - 60 years | 60 years

The reactor core contains 432 (for the Steel-1200) or 643 (for the Steel-1800) fuel assemblies (FAs), each consisting of 127 fuel rods - Sintered pellets of UO2 (with a maximum enrichment of 26%) and PuO2 (17.7% of the weight), with a Zirconum alloy tube cladding. Up to 27 control rods are placed inside the core.

As of December 2015, OCES operates 2 Steel-1200 power plants and 2 Steel-1800 power plants across Ostehaar, both type supplying around 27% of Ostehaar's electricity demand.

Oster nuclear program

Facilities of the nuclear fuel-cycle in Ostehaar

Ostehaar has no vast deposits of natural Uranium, and therefore OCES has to import around 90% of the Uranium it needs to operate Ostehaar's fuel-cycles and the partial fuel-cycles it operates in other nations. OCES currently operates six different fuel-cycles across The Western Isles - one in Ostehaar and the remaining five in other nations (see list above under 'Clients and collaborators'). Subsidiaries of OCES operate the Oster fuel-cycle, usually a company per facility, but not always.

Uranium is transferred into Ostehaar either in the form of Yellowcake (Triuranium Octoxide, U3O8) or in the form of unclean UNH (Uranyl nitrate, UO2(NO3)2). A small amount of Uranium mined in northern Ostehaar is extracted to Yellowcake in the Sjrihner Yellowcake Production Facility (SYPF). The Yellowcake is then inserted into the production lines of the Savare Conversion Facility (SCF) to convert it to 'HEX' (Uranium Hexafluoride, UF6, used in gas centrifuge enrichment) or to Urania (Uranium Dioxide, UO2, used as nuclear fuel).

The 'HEX' is then transferred in large containers to one of Ostehaar's two high-end Uranium enrichment facilities - the Grehem-Haalden Enrichment Plant (GHEP) or the Teser Bay Enrichment Plant (TEP). Both facilities belong to the Uranium Enrichment Industries of Ostehaar company, one of OCES' first subsidiaries.

Alongside its two large enrichment facilities, UEIO also has its own subsidiary called Ostehaar Centri-Tech (OCT), which operates a small research and development facility outside of Haalban. In this facility, OCT improves and tests new and existing centrifuge models and centrifuge cascades. OCT also manufactures the centrifuges, and sends them to UEIO to be used for industrial-scale enrichment in one of the large facilities.

The current standard centrifuge model used in UEIO's facilities is the O3 model - a 3 meter tall, 20 centimeters wide Carbon-fiber (T800) and Aluminium 7075 centrifuge, which operates at a maximum velocity of 770 meters per second (around 1,225 Hz or 73,000 revolutions per minute) and has a separative power of around 60 kgSWU/yr. In comparison, URENCO's current TC-21 centrifuges have similar technical characteristics, excluding their height of 5 meters, and a separative power of around 100 kgSWU/yr. Since the separative power increases linearly with height - this puts the O3 in line with the most efficient and advanced centrifuge models used for industrial-scale enrichment in the world today.

UEIO's facilities contain lines for enrichment of Uranium from its natural enrichment level (0.711%) to levels of around 4%, 30%, and 90% - as needed in OCES' various power and research reactors around the region. All facilities stand in IAEA regulations and are subjected to IAEA supervision and verification.

Enriched Uranium in the form of UF6 is then sent back to the conversion facility for conversion into UO2. The enriched Uranium in the form of UO2, along with natural Uranium in the form of UO2, are transferred to fuel fabrication plants for further processing to nuclear fuel for all types of reactors operated by OCES.

In the Oster fuel-cycle, OCES has two subsidiaries responsible for fuel fabrication - each operates its own plant. Osgruhn Fuels operates the Osgruhn Fuel Production Facility (OFPF), and OsterAtom operates the Ford River Fuel Production Facility (FFPF). OsterAtom also operates the Fuhrenahm Zirconium Plant (FZP), which produces the Zirconium cladding necessary for the production of nuclear fuel. OsterAtom's FZP serves both Oster fuel fabrication plants.

Nuclear waste created in all facilities is transferred to Esjtmer, to be temporarily stored in the Nuclear Treatment Complex (NTC) close to the border. After several month of storage, most of the nuclear waste is shipped to Illa Isle (Vancouvia) for long-term storage and disposal.

Nuclear reactors in Ostehaar:

A total of 9 nuclear power plants (8 of them as dual-unit plants) operate in Ostehaar, producing 10,680 MW of power altogether and supplying around 75% of Ostehaar's power demand (the rest is supplied mainly by locally extracted natural gas).
