If Russia can copy the increase in reactor power density for their BN-1200 that they did from BN-600 to BN-800, it would be an outstanding achievement. The difference in volume between BN-600 and BN-800 reactors was only 3% more, where as the power increase is 33% more.

Sorry I did not give source of numbers.

Its however important to realize that not only a fast reactor needs much higher enrichment, but also need a lot more fuel (around 5x), so the initial enrichment cost might amount to 10 years worth of enrichment cost for a regular reactor.
Unless you start off with reactor grade Pu, no?

Sure, whatever is cheaper... Some countries don't reprocess at all, so its either weapons grade Pu that needs disposing or highly enriched U235.
GE S-PRISM materials argue they need lots of new ESBWR, otherwise a fleet of S-PRISM would eat up all SNF available (since reprocessing is built into the design), which proves my point that fast breeders gob up a lot of Plutonium or HEU for startup.

Follow-up, from World Nuclear News, about the BN-800 fast reactor in Russia, which has reached full power. It will enter commercial operation later this year:

Russian fast reactor reaches full power

Although most of us on this forum do prefer molten salt reactors, I do think that this is still welcome news as the actual operation of this reactor is proof that 4th generation reactor technology is advancing, albeit slowly.

New units said safer, less radioactive waste

Quote:
On August 17, Unit 4 of the Beloyarsk nuclear power plant with BN-800 fast neutron reactor, which should become the most powerful prototype of the commercial reactors of this type, started operating at 100% power for the first time, State Atomic Energy Corporation Rosatom said in a press release. Thus begins the procedure of comprehensive testing of the unit at its rated power.

Russia deserves congratulations on their success. I can see this as a way to drive some international competition. Hopefully a friendly competition, out of national pride. While a less than friendly competition has provided a drive for considerable expenditures in science, technology, and engineering, the continuous threat of another war is not desirable.

In other words, I want one too.

World Nuclear Association: "Nuclear Power in Russia" (Updated 26 August 2016)
Quote:
• Russia is moving steadily forward with plans for an expanded role of nuclear energy, including development of new reactor technology.
• An average of one large reactor per year is due to come on line to 2028, balancing retired capacity.
• Efficiency of nuclear generation in Russia has increased dramatically since the mid-1990s. Over 20 nuclear power reactors are confirmed or planned for export construction.
• Exports of nuclear goods and services are a major Russian policy and economic objective.
• Russia is a world leader in fast neutron reactor technology.
Kirk, your forum didn't have a "Russia" board index.

This article has a lot of information on Russian civilian domestic nuclear power.

The BN-800 is located in the Urals, near Yekaterinburg and Sverdlovsk, on the border between Europe and Asia. Most people would group Russia with Europe, historically and culturally and because most Russians live in the European part of Russia.

Putin has suspended the agreement to destroy stocks of weapons grade plutonium. Whether that will affect progress on the BN 1200, or the way they fuel the BN 800, currently using uranium, is debatable. US progress with turning W-G plutonium into MOX had already stalled.

Update on BN-1200
Volume and Materials per MWe has been chopped in half

When I see this, SMR could seem expensive.

It dos look like they like there VVER-1200 more so then the BN-1200

Here is a wonderful video of of a VVER-1200 can being made.
