Experimental Comparative Study on Devices Measuring Field Moisture Content of Roadbed Materials
이상익,오정호,Sebesta, S.D. 한국방재학회 2015 한국방재학회논문집 Vol.15 No.6
For in-place moisture content measurements as a part of quality control (QC) of roadbed construction, many agencies rely on nuclear testing and physical gravimetric drying for moisture content measurements. In this study, alternative methods were initially evaluated to identify technologies that could be used to measure moisture content in the field substitute using gravimetric, dielectric, and electrical conductivity, and suction-based methods. The small scale field test and actual field tests were then performed to evaluate device bias and accuracy, and estimates of single-operator standard deviation of repeat measurements. Through those results, the list of most promising devices could be narrowed down.

As an example of research activities in decontamination for decommissioning, new data are presented on the options for corrosion layer dissolution during the decommissioning decontamination, or persulfate regeneration for decontamination solutions re-use. For the management of spent decontamination solutions, new method based on solvent extraction of radionuclides into ionic liquid followed by electrodeposition of the radionuclides has been developed. Fields of applications of composite inorganic-organic absorbers or solid extractants with polyacrylonitrile (PAN) binding matrix for the treatment of liquid radioactive waste are reviewed; a method for americium separation from the boric acid containing NPP evaporator concentrates based on the TODGA-PAN material is discussed in more detail. Performance of a model of radionuclide transport, developed and implemented within the GoldSim programming environment, for the safety studies of the LLW/ILW repository is demonstrated on the specific case of the Richard repository (Czech Republic). Continuation and even broadening of these activities are expected in connection with the approaching end of the lifespan of the first blocks of the Czech NPPs.
