“When building a machine as large and as complex as ITER, difficulties and setbacks do not come as surprises - they are an integral part of manufacturing, assembling and installing first-of-a-kind components,” the ITER Organisation said recently.

Problems will require in-depth examination and ‘time and budget’ to repair October 2022 file photo of the 30-metre-deep pit in the tokamak building being prepared for the Iter machine itself.

Defects have been identified in two key First-of-a-kind tokamak components for the International Thermonuclear Experimental Reactor (Iter) nuclear fusion plant under construction at Cadarache in southern France, with the €20bn project facing potential delays while repairs are carried out.

Iter said in a project update that the two components are the vacuum vessel thermal shields and the vacuum vessel sectors.

The issues “demand in-depth examination, creativity in devising corrective actions, and time and budget to repair”, Iter said.

The vacuum vessel thermal shields are actively cooled silver-plated elements, 20 mm thick that contribute to thermally insulating the plant’s superconducting magnet system operating at 4K, or minus 269C.

China’s "artificial sun", the HL-2M tokamak, has set a new operation record with its plasma current exceeding 1 million amperes (one megampere) “marking a major step toward fusion ignition”, China National Nuclear Corporation (CNNC) has announced. The tokamak, independently designed and built by CNNC’s Southwestern Institute of Physics (SWIP) in Chengdu, Sichuan Province, was completed in November 2019 and achieved its first plasma discharge in December 2020.

Tokamak Energy has announced plans for its advanced prototype, ST80-HTS, which will be the world’s first high field spherical tokamak using high temperature superconducting (HTS) magnets at scale. The company said ST80-HTS will demonstrate multiple advanced technologies required for the delivery of commercial fusion energy. “With build completion planned in 2026, it will also demonstrate the key operating advantages of the spherical tokamak and inform the design of the ST-E1 fusion pilot plant. This in turn will demonstrate the capability to deliver electricity into the grid in the early 2030s, producing up to 200 MW of net electrical power.”

Plant could offer ‘sustainable, carbon-free energy for generations’ GA said the plant could provide baseload energy without any harmful emissions or long-lived waste. Courtesy GA. US-based General Atomics has revealed a concept design for a nuclear fusion pilot plant featuring a steady-state, compact advanced tokamak capable of holding fusion plasma for extended periods of time and a liquid metal breeding blanket for generating tritium fuel.

The pilot facility would use the company’s proprietary fusion synthesis engine. The tokamak would use superconducting magnets to contain and shape the plasma with microwaves directed into the fuel to heat the plasma to over 100 million degrees Celsius. Silicon carbide would be used in the walls of the liquid metal breeding blanket that would breed tritium and carry heat away from the tokamak.

Fuelled primarily by isotopes of hydrogen found in seawater and capable of generating its own fuel during operation, the plant would provide baseload energy without any harmful emissions or long-lived waste, GA said. Capable of operating around the clock, commercialised fusion power plants would provide “sustainable, carbon-free firm energy for generations”.

“Excitement for fusion energy is at an all-time high, with historic interest from private industry and government,” said Anantha Krishnan, senior vice-president of the General Atomics Energy Group. “We look forward to working with our partners to make our vision for economic fusion energy a reality.”
