Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

The Analytical Laboratory (AN) of the JET Active Gas Handling System (AGHS) is a central facility of the AGHS connected via small bore tubes to the other AGHS sub-systems. It offers various techniques such as gas chromatography, mass spectrometry, ionisation chambers, katharometers and calorimetry, to characterise the various gas samples. The detection ranges of the gas chromatograph for the six hydrogen molecules, helium, nitrogen and oxygen are from about 100ppm to 100% and for methane, higher hydrocarbons, CO and CO2 from about 10ppm to 100% with a thermal conductivity detector and a flame ionisation detector, respectively. Similar detection ranges can be achieved with the quadrupole and omegatron mass spectrometers. In addition tritiated hydrogen and hydrocarbons will be detected with flow proportional counter detectors and ionisation chambers down to the low ppm range. Inactive commissioning results will be presented.
