SGN to supply radwaste mixer to Spain

30 April 2001

The Spanish national radioactive waste company, Enresa, has awarded SGN a contract to supply a new 500-litre mixer for solidification of low and medium level radioactive waste. The mixer will require a cement matrix (grout) formulation according to safety criteria set out by CSN, the Spanish nuclear regulatory authority. Other safety-related features include integral nuclear containment, uniform waste encapsulation and low rinsing volumes, which reduce secondary effluent generation.

SGN has supplied radwaste mixers to Canada, the US, Belgium, France, Switzerland and Taiwan, and is currently installing two units in Russia and Ukraine. The new mixer for Spain will be double the capacity of previously installed units.
