Molten fuel could also escape safety features designed to prevent it from achieving the critical mass that produces nuclear fission.

The mass was found to be homogeneous, primarily composed of molten fuel and cladding.

This would cause a release of fission products from the fuel matrix quite comparable to that of molten fuel.

The impact vaporised rock, blasting molten glass and lava into space.

For up to 20 hours a week, he blows air into molten glass to turn the material into intricate shapes and designs.

It was made by wrapping molten glass around a core, which was then destroyed after the glass set.

If particles are ingested into a jet engine, they clog it with molten glass, causing the engine to shut down.

I have never forgotten the rivers of molten glass and lead inexorably advancing over the twisted metal of the girders.

Suddenly the lighters became fiery, molten plastic projectiles that were catapulted out of the fire into the surrounding woods.

Attackers have used boiling water on their prisoners, or dripping molten plastic.

The gadget works by forcing molten plastic through nozzles to match a design on a computer.

The molten plastic flows through the runner and enters one or more specialized gates and into the cavity geometry to form the desired part.

In the externally heated type, molten plastic runs within a solid manifold and within the nozzles.

Two more are among the 34 treated in hospital after being struck by showers of molten rock and ash.

You've got nitrogen glaciers, enormous mountains of water ice, potentially cryovolcanoes [spewing out water and gases rather than molten rock].

Trapped and half-buried by the molten rock was charred deep-sea life, including the giant tubeworms that thrive at chemical oases even at this depth.

The mountain puts on an almost daily display of pyrotechnics, spurting red-hot molten rock high into the sky — a thrilling backdrop to a nighttime descent.

They noticed deposits of green molten rock fragments sandwiched between sandstones almost 1.2 billion years old.

The rings erupt in a shower of golden rain seemingly made from molten steel.

A couple of feet away a foot-wide river of molten steel gurgles past.

The hydrogen infuses into the molten steel and renders the welds brittle.

Its purpose was to maintain a reservoir of molten steel, which drained down and filled the pipe as the casting cooled.

The molten steel flows into the mould, fusing with the rail ends and forming the weld.

But a burner full of molten wax fell from one of them as it floated around 40ft up.

The ancient smell of molten wax fills the little theatre: two white hands flicker at a workbench.

By means of a pot with 2 spouts the moulds are filled with molten wax.

Typically, this treatment makes the substance softer, more like molten wax.

The aim being to catch the apples with your mouth without getting molten wax on your face.
