Small Nukes: "Here comes the next-generation reactor for Arctic floating plants"

From the Barents Observer, May 27:

The RITM-200S is a significantly upgraded next-generation small modular reactor designed for floating nuclear power plants. Installation work is now set to begin at a shipyard in St Petersburg. 

Rosatom on May 27 announced via Telegram that construction of the first reactor aimed for Russia's second-generation floating nuclear power plants has been completed. The reactor will now be sent by rail to the Baltisky Shipyard in St. Petersburg where it will be installed.

The Barents Observer has previously reported about the arrival of the first multistory barge-structure from China to the the yard earlier this spring. 

Each of the new floating nuclear power plants will be equipped with two RITM-200S reactors, a slightly modified version of the RITM-200 reactors Russia is using on its newest generation nuclear-powered icebreakers. 

While the icebreaker reactor model has a thermal capacity of about 175 MWth, the ones designed for power plant use have a capacity of about 198 MWth.

A total of four second-generation floating nuclear power plants - destined for Cape Nagloynyn on the northern coast of Chukotka in Siberia - will be built and delivered to the Arctic by 2031. 

According to Rosatom, the production plant in Podolsk has now delivered 13 RITM-200 reactors and one RITM-200S reactor. The state nuclear corporation added that 14 more are at various stages of production....

Russia of course has the floating power plant anchored off Pevek 800km northwest of the Bering Strait, and in a pinch the nuclear icebreakers can supply a lot of juice. Additionally Kaz Minerals will be installing four modular nukes to power their giant Siberian copper mine, all links after the jump....
