site. This technology has been known since the 1960s: for

instance, the U.S. floating nuclear power plant Sturgis was

used for ten years to provide energy to the Panama Canal

in case of a threat of an intentional failure of the groundbased

power supply system, but it was decommissioned in

1976. To date, despite the existence of many similar developments

in the world, the Akademik Lomonosov is the only

floating power unit in the world, which gives uniqueness

to the Russian project.

The FPU is equipped with two KLT-40S icebreaker-type

reactors with a capacity of 35 MW each – together they are

able to produce up to 70 MW of electricity and 50 Gcal/h

of heat energy in the nominal operating mode, which is

enough to support the life of a city with a population of

about 100 thousand people. In addition to the floating

power unit itself, the structure of the FNPP project 20870

includes hydrotechnical facilities that provide installation

and detachment of the FPU and transfer of generated

electricity and heat to the shore, as well as onshore

facilities for transmitting this energy to external networks

for distribution to consumers. Currently, specialists are

working on the creation of this infrastructure in Pevek.

One of the main features of the project being implemented

is the placement of two reactor units in a small

hull of the vessel while preserving all the functional

characteristics of the ground-based nuclear power plant

with fewer maintenance personnel. At the same time, the

highest reliability and safety of operation is provided with

no environmental impact.

The floating power unit is supposed to have a lifespan

of from 35 to 40 years. For its operation, low-enriched

uranium will be used, and spent fuel will be accumulated

on the platform itself. Once every three years, fuel will be

reloaded, with the average annual duration of the reactor

refuelling not exceeding 60 days. In addition, on an annual

basis, scheduled shutdowns will be carried out at the plant

for routine maintenance, the average annual duration of

which will be no more than 20 days.

In designing the Akademik Lomonosov, priority was

given to such aspect as the safety of its operation. The

technological solution for the design components of the

FNPP is based on the tried and tested reference technology

used on nuclear icebreakers since 1988. The icebreakers

Taimyr and Vaigach were used as prototypes – their reactor

units have operated without fail for several decades in

the most difficult conditions of the Arctic. At the same

time, it should be noted that the technologies of the reactor

facilities for the icebreaking fleet are constantly being

improved and have made a qualitative step forward since.

This development is taking into account the fact that

increasingly high demands are being placed on nuclear

safety in the world.
