New coolants, new fuels: A new generation of university reactors
Here’s an easy way to make aging U.S. power reactors look relatively youthful: Compare them (average age: 43) with the nation’s university research reactors. The 25 operating today have been licensed for an average of about 58 years.

Most databases in fusion research are devoted to a single topic, such as energy confinement, H-modes, profiles, or disruptions. To allow for a wider range of analysis, modeling, and validation tasks, the JETPEAK broad-based multipurpose database has been developed for JET. This database currently includes 27 065 stationary state (∂/∂t ≈ 0) samples and nearly 1000 scalar, one-dimensional (profiles), and two-dimensional (R and Z dependent) variables grouped into topical structures. A similar database has been created for the Tokamak à Configuration Variable (TCV), comprising 65 000 samples reaching back to early TCV operation in the 1990s. The breadth and flexibility of these databases allows them to be used for a wide variety of investigations such as modeling tasks, confinement scaling, testing, validation and benchmarking of algorithms and modeling codes, and long-term monitoring of device conditions, as well as for documentation.
