FNPP “Academician Lomonosov” Print

Floating nuclear co-generation plant (FNCP) “Akademik Lomonosov” is a pilot design of the set of small transportable power plants. JSC “Afrikantov OKBM” is the designer, manufacturer and complete supplier of power plants (two KLT-40C reactors of 150 MW thermal capacity and 38.5 MW electric power each), pumps, fuel handling equipment and auxiliary equipment.

For example, such 15 MW (e) power plant allows annual saving of 45 thousand tons of reduced fuel or diesel oil: the proposed power units can continuously operate during 10-12 years without refueling and repair while the total operation period is 40 years.

The investigations and design studies show the possibility to develop the new-grade power sources based on ship reactors mastered in Russia for commercial production of electric power, desalinated water, industrial and residential heat. They are 3.5 to 70 MW (e) floating nuclear power units.

Floating power unit (FPU) is an autonomous power facility, which is end-manufactured at the shipbuilding yard as non-self-propelled vessel towed by sea or river to the operation site. The Customer receives end-constructed, tested and ready for operation power facility with accommodation facilities and complete infrastructure for operation personnel living, i.e., the turnkey basis technology is implemented.

FPU shop fabrication reduces construction terms and costs to the maximum in case of commercial production and, at the same time, ensures the highest quality requirements. Expensive construction work is excluded at the plant site. If necessary, the FPU can be transported from one site to another.
To provide electric power for the large industrial plants, sea ports, sea shelf oil and gas production complexes, the JSC “Afrikantov OKBM” proposes 70 MW (el) FPU based on the commercial NPPs for ice-breakers.

FPUs are adapted in the best way for operation in hard-to-reach areas on the sea shore or by large riversides far from centralized power supply. In Russia, this means, first of all, electric power and heat supply to the enterprises and housing settlements in the Far North, which are not included in the unified electric power system and need autonomous power sources. Here they critically need several tens of small co-generation plants to stimulate economics and business and to support human activity in the settlements with a population up to 10 thousand. Electric power demand of such a settlement is about 20 MW. Same are the demands of the most mines and mining-and-processing combines.
Nuclear power and desalination plant (NPDP), which produces both electric power and high-quality fresh water was developed to be exported to shore areas of the countries and regions with dry climate. This plant includes FPU and floating desalination plant where reverse osmosis technology or many-stage evaporation plants can be used. Africa, Asia and Europe countries suffering from fresh water deficit show interest in these plants.

Fuel enrichment used in FPU plants does not exceed the ultimate level recommended by IAEA to observe nuclear weapons non-proliferation. It allows using of floating nuclear power sources within the international legislation including the developing countries.

As the plant will operate in the coastal districts of the world ocean, it shall withstand not only anthropogenous but environment effects, such as tsunami, tornados, etc. “Afrikantov OKBM” uses the technologies to fabricate the NPP in such a way that it can withstand any dynamic load specified in the design. It is confirmed both theoretically and practically: “Kursk” submarine cruiser reactor plants developed by “Afrikantov OKBM” specialists withstood the massive explosion resulted in crew loss and shut down autonomously in standard mode without exceeding of working temperature range.

Floating NPP protection barriers

According to current safety standards, the floating NPP is initially designed with safety margin, which exceeds theoretically the loads possible for the given region, such as tsunami wave shock or collision with another ship or building as a result of such shock.
If we speak about floating NPP safety, one should note that hundreds of ships with similar plants are operated as a part of fleet in Russia, USA, China, Great Britain, France and India. Modern missile cruisers, aircraft-carriers and nuclear submarines are often based in the ports near large cities.

The plant is repaired and refueled after it is transported to the special enterprise. Outside this enterprise, the fuel is kept in the reactor compartment, which is adopted for these purposes to the maximum.

When the lifetime is expired, the power unit is replaced for a new one, and the spent unit is transported to special technological enterprise in Russia for disposal. During operation and after operation completion, no ecologically dangerous substances and materials remain at the floating NPP site (greenfield site principle).
These safety aspects are linked in the single concept of human and environment radiation safety within all stages of FNCP life history.
