The article analyses the results of application of the radioactive waste activity measurement method based on measuring the energy distribution of gamma radiation near the container at the Novovoronezh NPP. The proposed method is applied to homogeneous radioactive waste and provides a reduction of the characterization costs. The results of an experimental study of the method and proposals for its improvement are presented.

Technical Considerations

Organic sorbents like peat can be successfully used for the purification of radioactive waste waters and are favoured by economical and technical considerations. The peat filters are also friendlier to the environment, since the manufacturing of such filters is a low emission process. This study examined the sorption of radionuclides 137Cs, 55Fe, 63Ni and 14C on peat samples. The initial radioactivity of the peat samples was studied before the experiments. Peat samples were taken from different bogs. Radionuclide solutions were prepared using deionised water and appropriate radionuclide composition from the Salaspils research reactor stock water. It was found that in all cases of peat samples, the main natural radionuclides were 210Pb, 40K and 214Bi. The artificial radionuclides 152Eu, 137Cs and 60Co were also found in the peat samples. Radionuclide sorption studies indicated that the initial radioactivity of the solution decreased in the case of radionuclides 63Ni, 14C, 55Fe and 137Cs. This confirmed that peat samples can effectively remove the radionuclides from radioactive water solutions.

Radiation Profile

Nuclear waste management facilities at Chalk River Laboratories (CRL) use below-ground “tile-holes” to store solid waste from various activities such as medical isotope production. After long periods of isotopic decay, some of the waste has decayed down to low activities and can be transferred to low-level waste storage facilities. This paper presents a method to verify the radiation level of the waste inside tile-holes by performing gamma radiation scans along the depth of waste storage tile-holes. Such measurements allow for noninvasive verification of tile-hole contents and provide input to the assessment of radiological risk associated with removal of the waste. Using the radiation profile system, the radiation level of the radioactive waste may be identified based on the radiation profile. This information will support planning for possible transfer of this waste to a licensed waste storage facility designed for low-level waste, thus freeing storage space for possible tile-hole re-use for more highly radioactive waste. CRL-developed small diode-based gamma radiation sensors have been used in these radiation scans. The diode sensors were deployed into verification tubes adjacent to the tile-holes to measure the radiation profile. Over 10 tile-holes have been scanned using this technique since 2009.
