USE OF Cs-137 CALIBRATION SOURCE IN EVALUATION OF BWR FUEL BURNUP
نویسنده
چکیده
The source is covered by a watertight steel cylinder which is fixed inside a 0.65 m long piece of ASEA-ATOM type BWR fuel channel. Inside the cylinder there is a 37 GBq Cs-137 pellet fixed to a wagon which can be driven up and down by means of a stepping motor. By moving the source, the repeatability of the geometrical positioning is attained. The amplitude and scanning speed are controlled by a remote control unit. A picture of the apparatus is shown in Fig. 1. The apparatus is easy to handle and decontaminate. The source can be transported in a custom made box (45 cm x 45 cm x 70 cm) under category II-Yellow.

متن کاملUtilization of 134Cs/137Cs in the environment to identify the reactor units that caused atmospheric releases during the Fukushima Daiichi accident
The Fukushima Daiichi nuclear power reactor units that generated large amounts of airborne discharges during the period of March 12-21, 2011 were identified individually by analyzing the combination of measured (134)Cs/(137)Cs depositions on ground surfaces and atmospheric transport and deposition simulations. Because the values of (134)Cs/(137)Cs are different in reactor units owing to fuel bu...
متن کاملTRIGA fuel burn-up calculations and its confirmation
The Cesium (Cs-137) isotopic concentration due to irradiation of TRIGA Fuel Elements FE(s) is calculated andmeasured at the Atominstitute (ATI) of ViennaUniversity of Technology (VUT). The Cs-137 isotope, as proved burn-up indicator, was applied to determine the burn-up of the TRIGAMark II research reactor FE. This article presents the calculations andmeasurements of the Cs-137 isotope and its ...
متن کاملGamma-ray Emission Tomography: Modelling and evaluation of partial-defect testing capabilities
Assessment of gamma emission tomography (GET) for spent nuclear fuel verification is the task in IAEA MSP project JNT1955. In line with IAEA Safeguards R&D plan 2012-2023, the aim of this effort is to “develop more sensitive and less intrusive alternatives to existing NDA instruments to perform partial defect tests on spent fuel assemblies prior to transfer to difficult to access storage". The ...
متن کاملPreliminary Investigations of the Contribution of Scatter Radiation During Calibration of TLD-100 Using a Cs-137 Panoramic Source
Studies were carried out to determine the contribution of secondary photons to the calibration set-up of a Secondary Standard Dosimetry Laboratory. In these studies the response of LiF:Mg TLD-100 to known exposures using Cs-137 panoramic-source were investigated. Each TLD chip showed a linear dose response to radiation, demonstrating a typical characteristic of LiF:Mg chips. Whilst TLDs showed ...
