Most answers can be found in the pages of the 2023 issues of Nuclear News—if you’ve been a diligent NN reader you should do fine!

Scoring: Zero to five correct answers out of the 20 questions means you may need to read up on energy in order not to be at the mercy of others. Six to 10 correct answers is a good passing grade. Eleven to 15 right answers means you’re really energy literate. Sixteen to 19 correct answers means you should be advising Congress. Twenty right answers suggests you’re Mr. Spock reincarnated.

U.S. to help rid Norway of HEU

The U.S. Department of Energy and Norway’s Ministry of Trade, Industry, and Fisheries have signed a memorandum of understanding to advance a project aimed at eliminating Norway’s high-enriched uranium by downblending it to low-enriched uranium. If the project is successfully completed, Norway will become the 34th country (plus Taiwan) to be considered HEU-free.

In the downblending process, HEU is mixed with depleted or natural uranium to reduce the U-235 concentration to below 20 percent, resulting in LEU, which cannot be used to make an improvised nuclear device (aka “dirty bomb”). According to the DOE’s National Nuclear Security Administration, the challenge with Norway’s HEU has been that much of it is mixed with thorium, making the use of other disposition techniques more problematic.

A closer look: Signed on September 1 by U.S. energy secretary Jennifer Granholm and her Norwegian counterpart, Iselin Nybø, minister of trade and industry, the MOU calls for small-scale downblending activities to begin in 2022 using Norway’s existing infrastructure. It also paves the way for the eventual deployment of the DOE’s Mobile Melt-Consolidate system to complete the work.
