to be carried out with the same equipment:
evaporation of the waste solution mixed with the additives necesary for
the production of borosilicate glass, calcination and elaboration of the
glass. These operations are carried out in a metallic pot that is heated
in an induction urnace. The vitrification of one load of wastes
comprises of the following stages. The first step is 'Feeding'. In this
step the vitrification receives a constant flow of mixture of wastes and
of additives until it is 80% full of calcine. The feeding rate and heating
power are adjusted so that an aqueous phase of several litres is
permanently maintained at the surface of the pot. The second step is the
'Calcination and glass evaporation'. In this step when the pot is
practically full of calcine, the temperature is progressively increased up
to 1100 to 1500 C and then is maintained for several hours so to allow the
glass to elaborate. The third step is 'Glass casting'. The glass is cast
in a special container. ...

absence of volatile products and
good radiation resistance. The ruthenium that escapes is absorbed by a
filter. The amount of ruthenium likely to be released into the environment
is minimal.
Another method that is being used today to get rid of radioactive
waste is the 'placement and self processing radioactive wastes in deep
underground cavities'. This is the disposing of toxic wastes by
incorporating them into molten silicate rock, with low permeability. By
this method, liquid wastes are injected into a deep underground cavity
with mineral treatment and allowed to self-boil. The resulting

steam is processed at ground level and recycled in a closed system. When
waste addition is ...
