Cold, powerful magnet will help control hot plasma in fusion reactor

A team at ITER, an international experimental fusion reactor in southern France, prepare on Feb. 10, 2022, to move one of six modules for a central solenoid, a powerful superconducting magnet being built by General Atomics in California under the management of Oak Ridge National Laboratory.

A magnet so powerful it could lift an aircraft carrier six feet into the air was designed in a project managed by Oak Ridge National Laboratory. It will be used in an international experimental reactor in southern France to produce energy using fusion, the same process used by the sun and other stars to create heat and light. If successful, the reactor could revolutionize energy production, potentially showing how to provide a nearly limitless energy supply without planet-warming carbon dioxide emissions or long-lived radioactive wastes.

Six modules for the reactor’s central superconducting magnet, plus a spare, are being made by General Atomics in Poway, California. Two of the modules have already been shipped to France. Two more are completed, with one of those expected to ship this year. The remaining three are more than 60% complete, and manufacturing should be done this year, said John Smith, General Atomics senior director of engineering and projects.

Y-12 supporting work to make most widely used medical isotope

The Y-12 National Security Complex in Oak Ridge is supporting a program to make an isotope used in more than 40,000 medical procedures across the nation each day. The goal is to produce the isotope, molybdenum-99 (Mo-99), in the United States without using highly enriched uranium.

Some of that work could occur in Oak Ridge. A company called Coquí Radio Pharmaceuticals Corporation announced in April that it plans to build a $500 million medical isotope production facility at the Heritage Center in west Oak Ridge. Coquí’s facility would make medical isotopes, primarily Mo-99, and the company could start production in 2025.

In a video posted online, Y-12 said some of its researchers have extensive knowledge of Mo-99 and are sharing that information with Coquí and other companies hoping to produce the isotope.

Y-12 has been involved with Mo-99 since 2009, said Cole Jackson of Y-12 Global Security and Strategic Partnerships.

Depending on protests, transition to new Y-12, Pantex contractor could start in November

Y-12 National Security Complex Sign

The transition to a new contractor at the Y-12 National Security Complex in Oak Ridge and Pantex Plant near Amarillo, Texas, could start later this month—after the period for protests is over, federal officials said Friday afternoon.

The transition to a new contractor at the Y-12 National Security Complex in Oak Ridge and Pantex Plant near Amarillo, Texas, could start later this month—after the period for protests is over, federal officials said Friday afternoon.

The protest period ends around Nov. 25, the National Nuclear Security Administration said. The transition could start the day after the protest period ends and last four months, but the NNSA will ask the new contractor, Consolidated Nuclear Security LLC of Reston, Va., to complete the transition quicker if possible.

It’s not clear yet if the two teams that submitted unsuccessful bids will lodge new protests. There have already been two rounds of protests over the contract, which could be worth up to $22.8 billion during a 10-year period, and they have delayed the transition. The NNSA said it will not speculate on the possibility of any new protests. [Read more…]
