“…Many papers deal with the measurements of 14 C in environmental or biological samples [10] but a very few in nuclear waste [8,14]. The major difficulty of 14 C determination in radioactive waste deals with its complete extraction from the matrix, especially for steel samples [6,8,14,[27][28][29] and the elimination of volatile interfering radionuclides such as 3 H, 129 I, 99 Tc or 35 S before LSC analysis. In agreement with the literature, two methods (e.g.…”

This paper reports the results obtained during an intercomparison exercise for the determination of difficult to measure radionuclides in activated reactor pressure vessel (RPV) steel samples. In total, eight laboratories participated analysing 14C, 55Fe and 63Ni activity concentrations in RPV steel. In addition, some laboratories also analysed 60Co activity concentrations. Corresponding activity concentrations were also determined using activation calculations. Robust statistical techniques were utilised for the analysis of the results according to ISO 13528 standard. The results showed good agreement for 55Fe and 63Ni results whereas 14C results had significant differences. 60Co results were in quite good agreement.

Determination of the ¹⁴C Content in Activated Steel Components from a Neutron Spallation Source and a Nuclear Power Plant

The (14)C content in activated steel components from the Swiss Nuclear Power Plant (NPP) Gösgen and the Spallation Neutron Source SINQ at the Paul Scherrer Institute is determined using a wet chemistry digestion technique and liquid scintillation counting for (14)C activity measurements. The (14)C activity of an activated fuel assembly steel nut from the NPP is further compared with theoretical predictions made on the basis of a Monte Carlo reactor model for this NPP. Knowledge of the (14)C inventory in these activated steel materials is important in conjunction with future corrosion studies on these materials aimed at identifying the (14)C containing organic compounds possibly formed in the cement-based near field of a repository for radioactive waste.
