Abstract This study examined the performance evaluation and analysis of laboratories Spanish Nuclear Power Plants over last 9 years 34 editions organized by CIEMAT. The participating nuclear power plants were Almaraz, Ascó I, II, Cofrentes, Santa María de Garoña, Trillo, Vandellós II. radionuclides analyzed those necessary to ensure operational radiological protection control liquid effluents from a plant. are classified into beta emitters: 3 H, 14 C, 90 Sr, gamma 241 Am, 57 Co, 137 Cs, 60...
During some pressurized water reactor risk-dominant sequences, most of the radioactivity is discharged at very high velocities into nearly saturated pools. An experimental plan for pool scrubbing and its associated hydrodynamics under representative boundary conditions carried out in PECA facility. The retention tests show that a substantial fraction particle absorption takes place entrance because inertial removal mechanisms. This submergence-independent component decontamination factor...
The 4πγ-counting technique is recognized as a powerful primary method for the standardization of radionuclides decaying with abundant gamma emissions. Based on use detector in quasi 4π-geometry, detection efficiency close to 100% and low uncertainty can be achieved thanks summing effect subsequent transitions. Uncertainties have assigned realistic modelling source–detector geometry respect dimensions, density material composition, calculation total counting various emitted radiation,...
Two series of activity standards (60)Co in cast steel matrix, developed for the calibration gamma-ray spectrometry systems metallurgical sector, were characterised using a European interlaboratory comparison among twelve National Metrology Institutes and one international organisation. The first standard, consisting 14 disc shaped samples, was from contaminated during production ("originally"), second, 15 similar discs, artificially-contaminated ("spiked") steel. reference concentrations...
A comparison was conducted, between 11 European National Metrology Institutes and EC-JRC, on measurement of 137Cs activity concentration in fume dust. As test material an standard produced from real contaminated dust used. The consisted 13 cylindrical samples compressed contained 60Co reference concentrations (9.72±0.10) Bq/g (0.450±0.018) Bq/g, respectively, for the date 1 June 2013, determined using results. organization results intercomparison, as well process obtaining reliable values...
