- n. an alloy of magnesium and aluminium used, with a non-oxidizing cover, as cladding for fuel rods in Magnox nuclear power stations
Sorry, no etymologies found.
Intermediate level waste mainly comprising magnox fuel cladding was stored under water within the facility.
The biggest threat was to Thorp because the remaining two evaporators were needed to deal with the high hazard radioactive liquor stocks and magnox reprocessing.
I speculate that this is probably because magnox alloy, being non-radioactive, is harder to detect than uranium.
As Vitaly Fedchenko explains in this excellent article environmental samples are first screened by the IAEA using high resolution gamma ray spectrometry to detect radioactive particles-and that ain't much help in looking for magnox alloy.
This leads me to conclude the particles must be metallic uranium as this is what's used in magnox fuel.
