What is National Nuclear Energy Commission known for in research?
The fields where it stands highest, 2022-now, ranked among every institution above the floor in each field.
| Field | World rank | Where that sits | Top-10% rate | Works | All time |
|---|---|---|---|---|---|
| Materials ScienceField | #1,961 of 2,276 | 2.9% | 70 | #3155 | |

Each strip is that field's whole ranked pool, with the notch where National Nuclear Energy Commission sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no average mark, because the average differs by field (from about 6% in Dentistry to 21% in Economics).
Which of those standings moved
The same fields on both windows: where it stood over the whole record, and where it stands in 2022-now. The distance is the story, and it is the one thing the two rank columns above cannot show.
- Materials Science#3,155 #1,961
