French nuclear designers tap American expertise
INL nuclear engineer John Bess helped analyze a new French fast reactor design.

The world's nuclear experts have reached out to U.S. Department of Energy engineers for help evaluating a new nuclear reactor design that could increase safety margins while reducing waste.

The project marked a series of firsts for nuclear engineers on both sides of the Atlantic. They fostered a new collaboration and tapped state-of-the-art analysis tools to evaluate a first-of-a-kind reactor design.

France's Atomic Energy and Commission (CEA) collaborated with nuclear engineers at DOE's Idaho National Laboratory and Argonne National Laboratory for the project. Its goal: assess and performance parameters for a new fast reactor design.

The Advanced Sodium Technological Reactor for Industrial Demonstration (ASTRID) is intended to significantly improve resource utilization, potentially produce less radioactive waste, and increase safety margins compared to current technology. The design offers inherent protection because the fission process would slow down naturally even if the reactor shutdown capability is lost, and passive decay systems would keep the cool.

Before such a can be built, those safety assumptions need to be checked and rechecked. That's where the DOE national labs come in. The effort used cutting-edge analysis tools, and the findings verified French predictions while highlighting where to focus future efforts.

"We have tools and data today that we didn't have 15 years ago," said INL Fellow Giuseppe Palmiotti, who led the lab's contribution. "Plus, this enabled young American engineers to evaluate a unique design with a promising outlook."

Your "top experts" in nuclear design are lacking in their understanding of the operation of electrons and atomic particles and their inter nucleation.. how it is put together, and how it can be taken apart. So neandrathal in their thinking that round wheels have not yet been invented.. Wow, and you run this world..Electrons are always "moving", or at least their energy is moving, and this is the reason that matter can hold together at all..Motion, should also take part in its breakdown, not rods, not pellets but something that will rotate at a certain speed, in a certain atmosphere and with a laser light power extraction with precision... How is it that we do not already understand this, which is self evident..Where is the thinking?
