Final storage of radioactive substances in special UHPC concrete container or strong rooms

One way to encapsulate such substances more
safely and cost-effectively than is currently
practiced is to pour into UHPC Ultra High
Performance Concrete blocks. UHPC has a
large number of advantages over the previous
storage in barrels of different material quality
and pouring into glass.

The advantages of new designs are:
 - UHPC is very easy to process as a casting
    and spraying compound.
 - UHPC has an extremely high pressure
    resistance compared to all standard concretes
 - UHPC is completely waterproof
 - What is poured into UHPC can not corrode
    anymore
 - UHPC is saltwater resistant
 - UHPC also hardens under water
 - UHPC in its high temperature version can
   be used at continuous temperatures up to
   1200°C/ 2192°F. This means that the
   UHPC HT (High Temperature) block is
   stable with internal temperature increase
   as well as with external fire.
   A secure above-ground storage against
   theft is possible because the blocks are heavy,
   large and therefore unwieldy for a quick
   removal. Getting the radioactive material out
   of the block is only possible with extreme
   effort and tools and time.
 - UHPC is based on nanotechnology, the material 
   particles are extremely fine. Almost allother
   particles are surrounded by this glue from
   extremely fine particles. Even with a break of a 
   UHPC block, the foreign matter is firmly trapped
   in the debris.
- It is easy to mix radiation-reducing materials into
   the block
-  UHPC concretes can be very good heat-insulating 
   or very good heat-conducting. It's just a question 
   of the UHPC concrete mixture

The advantages of sealing existing deposits are
  • UHPC casting compounds can have a very high                       flowability and easily penetrate into cracks and                          joints and seal them.
  • UHPC casting compounds are self-compacting.
  • All casting compounds are pumpable and sprayable
  • All casting compounds reach more than 70%                            after 48 hours
