  • Study of the Radioactive Silt Sediment Cementation

    Study of the Radioactive Silt Sediment Cementation

    Dec 12, 2010 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.

  • Cementation an overview ScienceDirect Topics

    Cementation an overview ScienceDirect Topics

    Cementation is beneficial to thick sands for the formation of good reservoirs. The middle part of thick sands is even good for high porosity development. According to the correlation between mid-deep reservoir properties and the content of carbonate cement in the Raoyang Sag, when the shortest distance from sandstone to mudstone is less than 0.5 m, the content of carbonate cements is usually ...

    The UK Triassic Sherwood Sandstone aquifer Springer

    Oct 29, 2019 Fluvio-aeolian sedimentary successions host groundwater aquifers at shallow depths ( ~0.15 km), which overlie geothermal and shale-gas reservoirs, and nuclear waste repositories at intermediate depths (~0.15–2.0 km). Additionally, such deposits represent petroleum reservoirs at greater depths (~2.0–4.0 km). The need to improve conceptual understanding of the hydraulic behaviour of …

    Radiation resistant concrete for applications in nuclear

    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 0.56, which likely resulted in the high measured permeability, yet the mixture also showed a compressive strength greater than 6 000 psi after 28 days.

    Jul 01, 2013 Abstract. A cement solidification process for treating sodium borate waste produced in pressurized water reactor (PWR) plants was studied. To obtain high volume reduction and high mechanical strength of the waste, simulated concentrated borate liquid waste with a sodium / boron (Na/B) mole ratio of 0.27 was dehydrated and powdered by using a wiped film evaporator.
