China and US molten salt nuclear reactor cooperation

A Cooperative Research and Development Agreement, or CRADA, between ORNL and SINAP focuses on accelerating scientific understanding and technical development of salt-cooled reactors, specifically fluoride salt-cooled high-temperature reactors, or FHRs. The project will draw on ORNL’s expertise in fuels, materials, instrumentation and controls, design concepts, and modeling and simulation for advanced reactors, as well as the lab’s experience in the design, construction and operation of the Molten Salt Reactor Experiment, the only molten salt reactor ever built.

The Chinese Academy of Sciences (CAS) has provided resources for research, technology development, design, and construction of an FHR test reactor in China. This initial test reactor will have a maximum thermal power of 10 megawatts. A second, 100-megawatt test reactor is also planned. Both FHR test reactors will use low-enrichment uranium fuel.

FHRs are an emerging class of salt-cooled reactors that feature low-pressure liquid fluoride salt cooling and solid coated particle fuel. This design provides a high-temperature power cycle that improves efficiency and a passive safety system designed to handle potential accident conditions without human intervention. FHRs have the potential to economically and reliably produce large quantities of carbon-free energy (both electrical and thermal), but technical challenges remain.

China's timeline was presented in 2013.

Berkeley and others have FHR reactor designs

There was a Jan, 2014 Current Status of the UCB PB-FHR Mark-1 Commercial Prototype Design Effort presentation

Current FHR Development Efforts

• DOE Integrated Research Project (IRP) – Collaborative university effort with MIT, UCB, and UW – Includes commercialization strategy, commercial prototype and test reactor pre-conceptual design effort, and assorted technology development efforts
• Oak Ridge National Laboratory – Ongoing FHR development work on technology roadmap and reactor design (plate fuel)
• ANS Standards Committee 20.1 – Currently developing FHR-specific GDCs and design standards
• Shanghai Institute of Applied Physics (SINAP) – Currently developing FHR and MSR technology – 10 MW FHR test reactor deployment planned for 2017

Leave it to the Feds to actively favor China over the USA.

Thorium? Any work on that?

[ckilmer]

there are US thorium msr companies but they’re not getting doe support.

Lower-cost nuclear reactors, which use Thorium as the major “fuel”, and the molten-salt heat exchange from the core to the power generation portion of the plant, have been a practical way to utilize atomic energy for several decades. Its major disadvantage (and the reason it was not widely adopted years ago) is that fissile material, like Plutonium, cannot be extracted from the “spent” fuel rods, and government entities are interested in building nuclear weapons.

If Iran were interested only in the power generation from nuclear sources, this is the technology they would be pursuing. Their main objective is to build nuclear weapons, and putting them on launch vehicles capable of intercontinental targeting.

And Holdren’s DOE really doesn’t want ANY energy policy to succeed, but Holder and Obola’s White House really DOES want Chinese reactors to succeed .....

Thorium is extracted from coal. The coal could then be converted to petroleum using the heat generated from the reactor.

Cheap energy, but everyone know coal is bad.
