Power stations and the grid, sentence 10
In a nuclear power station, uranium atoms split and give off heat, which makes steam to spin turbines; a small pellet of uranium fuel holds about as much energy as a tonne of coal, and the sites are guarded and tightly controlled.
Who acts: uranium atoms, heat, steam, small pellet · What happens: split, give off, make, spin, hold, guard · To what, where: nuclear power station, heat, steam, turbines, much energy, sites
This is a sentence of the lesson «Power stations and the grid» of the technology course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (uranium atoms, heat, steam, small pellet), what happens, when and where, as Mova's frames read it from the tree.
