A conference has been organised by the CNRS researchers in Grenoble, which takes place today and tomorrow, on the subject of the safety aspects of the MSFR:

http://lpsc.in2p3.fr/Indico/conferenceO ... onfId=1086 (in French)

The former EVOL project is likely to be continued under the new EU Horizon 2020 research framework as the SAMOFAR project, which is good news.

Most of the presentations are now available as PDFs:

The slides are in French, as NEEDS is a domestic French research programme, funded by the CNRS.

Thanks Camiel.

There are some papers in english.

In one presentation the autor says that only the SFR has a sufficient level of maturity to have a generation 4 industrial prototype before 2050. The VHTR, the LFR and the GFR could have small prototypes before 2050. For the SCWR and the MSFR he says that it seems difficult to have realisations before the end of this century.

Seriously the ARE worked in 1954 and we can not now make reactors before the end of this century ? And the public will not accept the SFR except if there are great manifestations of climate change and hydrocarbon shortages. And now the ESBWR at 10 billions $ ...

Let us hope that it is just a bad pass for nuclear power in Europe and America and that things will improve soon.

It sounds like the authors plan on building their prototypes a couple of years after the fusion people are ready with their reactors. Many of these researchers seem to believe they can milk the development cow until their retirement party. /sarc

There are already some VHTR prototypes in operation (for example in China). Russia will build a LFR by 2020 (the BREST-300). So this is long before 2050. An MSR, like the DMSR being developed by Terrestrial Energy, may become operational in the next decade. The MSFR is more complex (materials, online reprocessing), but is IMHO, still a much simpler machine than something like the ITER tokamak fusion reactor, where you have to deal with temperatures of over 100,000,000 degrees C , versus temperatures of approx. 800 degrees C . And guess, speaking of milking the development cow, where the bulk of the nuclear energy research funding is spent on ?

There was a workshop on the MSFR this week (on Tuesday October 20th, to be precise), which was organized by the CNRS and the IRSN, the French public body involved in nuclear research and nuclear safety.

General information: https://lpsc.in2p3.fr/Indico/internalPa ... onfId=1311

The slides of this workshop have been made public and focus on the safety aspects of the MSFR, as the MSFR is the reference design for the EU SAMOFAR project, in which the CNRS and IRSN are also involved:

https://lpsc.in2p3.fr/Indico/conference ... onfId=1311 (the slides are often a mixture of French and English)

Especially interesting is the one, by Herve Rouch and Olivier Geoffrey, on the different geometries considered for the MSFR.


The SAMOFAR project, which is coordinated by the Delft University of Technology in the Netherlands, has also started last month:

A little bit of flow channeling would go a long way in fixing some of the thermohydraulic-fluid dynamic issues with the MSFR.

I think that an MSFR could be run in a calandra.
Fill the main tank with fuel. Give protective cladding to all the surfaces in contact with it.
Run coolant in tubes.
Use thorium strips as control. You may need a lot of them. There could be a metallic thorium lining as blanket, if desired.
