The cement waste form samples used to evaluate the disposal feasibility were prepared at the w/c ratio of, which is the optimum operating condition. The cement waste form samples underwent a compressive strength test, a thermal cycling test, a water immersion test, and an irradiation test, after which the compressive strength was measured.
Indrum cementation is the standard solution for cementation of liquid radioactive waste inside a 200 l drum. The InDrum Mixer is a combination of a planetary mixer with counterrotating, double helical mixer elements. It is a well proven technology, and the ... • Small water/cement ratio .
Minimizing the volume of radioactive waste generated during dismantling of nuclear power plants is a matter of great importance. In Japan waste forms buried in a shallow burial disposal facility as low level radioactive waste must be solidified by cement or other materials with adequate strength and must provide no harmful opening. The authors have developed an improved method to minimize ...
Radioactive waste with widely varying characteristics is generated from the operation and maintenance of nuclear power plants, nuclear fuel cycle facilities, research laboratories and medical facilities. This waste must be treated and conditioned, as necessary, to provide waste forms acceptable for safe storage and disposal.
In addition, it was tested for compressive strength and permeability, important for nuclear infrastructure. The studied mixture had a high water to cement ratio of, which likely resulted in the high measured permeability, yet the mixture also showed a compressive strength greater than 6 000 psi after 28 days.
Abstract. This paper studied the influences of additives with zeolite, vermiculite, silica fume and quartz sand on the performances of the cementation of simulated radioactive fluoride liquid wastes, which mainly contains Cs +, Sr 2+, F −, etc. Different additives were added into the cement formulation with water/cement ratio of, and then cemented waste forms were made in the Φ50 mm ...
1 CEMENTS IN RADIOACTIVE WASTE DISPOSAL GLASSER University of Aberdeen, Scotland, United Kingdom Abstract The use of cement and concrete to immobilise radioactive waste is complicated by the wide ranging nature of inorganic
Cementation Background If radioactive liquid or solid waste needs to be converted into a product suitable for final storage, cementation is one of the methods commonly used. Cement is readily available and inexpensive for use in solidifying liquid or wet solid waste, and also for encapsulating solid waste generated during operation of a power
This chapter discusses the cementation technology used for immobilization of radioactive waste. The practice of encapsulating radioactive waste in ordinary Portland cement (OPC) began during the early years of the nuclear industry due to its low cost, availability and compatibility with aqueous waste.
The numbers are the oxygen isotope readings measured by the instrument. The variation in these readings is due to changes in the deep groundwater filling this porosity whilst the cement was growing during burial of the sandstone. Interpretation of such analyses enables a palaeohydrogeology of the sandstone to be reconstructed.

Abstract. Thermally expanded graphite (TEG) may be used for solidification of radioactive waste oils produced by the nuclear industry. TEG synthesized within the scope of this work retains the properties of a loose powderlike material when saturated with oil at the ratio of 20 g of oil per 1 g of TEG.

In Japan waste forms buried in a shallow burial disposal facility as low level radioactive waste must be solidified by cement or other materials with adequate strength and must provide no harmful opening. The authors have developed an improved method to minimize radioactive waste volume by utilizing radioactive concrete for fine
Radioactive silt deposits (RSD) of the spent fuel rod cooling pools were used as an object of these studies. In this paper the following techniques were considered for the silt processing: the cementation of silt without a prior treatment, cementation of the dried silt product, cementation of the calcined silt product, and the impregnation of the calcined silt with high penetrating cement grouts.
