Some astronomers believe that the solar system was formed by spallation when the sun was a very young star. From Wordnet, Princeton University.
Deuterium would be annihilated requiring the present abundance to have been produced at some later stage, such as spallation in shocks around the hypernovae of PopIII stars. From Wordnik.com. [Dark Matter: Still Existing] Reference

Thus, a spallation source plus a sub-critical fast reactor can be a copious source of fast neutrons. From Wordnik.com. [The Philosopher's Stone] Reference
If you really want a big flux of high energy neutrons, failing some major breakthrough in fusion technology, you want a "spallation source.". From Wordnik.com. [The Philosopher's Stone] Reference
There are two main natural sources of neutrons in the terrestrial environment, spallation by cosmic rays, and spontaneous fission, primarily of uranium238. From Wordnik.com. [The Neutron Dance] Reference
An accelerator with such a performance will be only a few times more powerful than existing meson factories in Los Alamos and Villigen and comparable with new spallation neutron sources proposed in. From Wordnik.com. [Accelerators and Nobel Laureates] Reference
Accelerator-driven neutron sources, often called spallation sources, are usually pulsed and they have, compared to research reactor neutron sources, a potential of providing substantially higher neutron fluxes. From Wordnik.com. [Accelerators and Nobel Laureates] Reference
In an Accelerator Driven System (ADS), high-energy neutrons are produced through the spallation reaction of high-energy protons from an accelerator striking heavy target nuclei (lead, lead-bismuth or other material). From Wordnik.com. [Thorium] Reference
He actually believes that ALL nucleosynthesis (fusion and spallation) occurs in flares and the magnetic / electric fields either on the photosphere, below the surface of the photosphere, and in flares. (just ask and see the responses of his EU/PC mates sorley (avatared sometimes as Tim Erney) and Anaconda.). From Wordnik.com.

Jefferson Tester patented a drilling technology called hydrothermal spallation. From Wordnik.com. [t r u t h o u t] Reference
In spallation, a high-energy proton bombards a heavy atomic nucleus, causing it to become excited, and 20 to 30 neutrons are expelled. From Wordnik.com. [Featured Articles - Encyclopedia of Earth] Reference
In this, up to ten percent of the neutrons could come from the spallation, though it would normally be less, even where actinide incineration is the main objective. From Wordnik.com. [Featured Articles - Encyclopedia of Earth] Reference
The capability of high-current, high-energy accelerators to produce neutrons by spallation from heavy elements has been used in the structural research of such materials. From Wordnik.com. [Featured Articles - Encyclopedia of Earth] Reference
In written evidence to the inquiry, Prof Creagh said: "The fragments which were removed were most probably spallation products caused by the impact of projectiles nearby.". From Wordnik.com. [Latest News - Yahoo!7 News] Reference
In such a subcritical nuclear reactor, the neutrons produced by spallation would be used to cause fission in the fuel, assisted by further neutrons arising from that fission. From Wordnik.com. [Featured Articles - Encyclopedia of Earth] Reference
Given that Bob Potter hashed out the initial calculations for hydrothermal spallation by hand - "I never did get into computers," he says - any risk-taking venture capitalist's money probably will go far. From Wordnik.com. [t r u t h o u t] Reference
The SNS actually became a world-record holder in August 2007 when it reached 160 kilowatts, earning it an entry in the Guinness Book of World Records as the world's most powerful pulsed spallation neutron source. From Wordnik.com. [Nano Tech Wire] Reference
It looks likely that it'll be built in Lund, Sweden, and is planned to be completed by 2019. spallation means that when something moving fast hits something heavy you get bits of stuff flying out of the heavy thing as a result. From Wordnik.com. [The Plummet Onions] Reference
Properly dispersed in the mesosphere, 1,000 pounds of Carbon Deoxidizer is enough to remove approximately two billion tons of carbon dioxide gas from the atmosphere before the Carbon Deoxidizer molecules are themselves destroyed by cosmic ray spallation. From Wordnik.com. [365 tomorrows] Reference
Development Goals 65 mA No ion source in the world at present can produce all the outputs required for next 1.0 ms, 50 Hz (short pulse) generation accelerator ≈ 2.5 ms, 50 / 3 Hz (long pulse) projects such as new spallation neutron (possibly interleaved?) sources and neutrino factories.
