Processing of Radioactive Waste Solution with Zeolites, (I)

The use of zeolites for the treatment of radioactive waste

The uptake of 137-Cs and 90-Sr on to synthetic zeolite A has been studied. The use of a combined barium exchange followed by a relatively mild heat treatment has been shown to fix the isotopes within a collapsed zeolite structure. Leaching experiments using deionized and simulated sea and pond waters were carried out on zeolite compacts and zeolite/cement composites. They demonstrated the effec...

Disposal of Radioactive Waste

Perhaps the most important single problem arising from the increasing use of atomic energy for peaceful purposes is how to dispose of the growing amounts of radioactive waste. Many of its complex aspects were discussed at the scientific conference on the disposal of radioactive waste held by IAEA in Monaco from 16 to 21 November 1959. The conference was organized jointly with UNESCO, with the c...

Waste management Radioactive waste management policies

Eight senior government representatives outlined the views and policies of their countries in the field of radioactive waste management at a "scientific afternoon" during the 27th Regular Session of the General Conference of the IAEA in Vienna in October. The countries represented were Argentina, France, the Federal Republic of Germany. India, Japan, Sweden, the United Kingdom, and the USA; sta...

Optimization of radioactive waste storage.

In several countries, low-level radioactive wastes are treated and stored awaiting construction and operation of a final repository. In some cases, interim storage may be extended for decades requiring special attention regarding security issues. The International Atomic Energy Agency (IAEA) recommends segregation of wastes that may be exempted from interim storage or ultimate disposal. The pap...
