Researchers of the HUN-REN Centre for Energy Research have been developing atmospheric dispersion and dose calculation tools since decades to assess radiological consequences of atmospheric releases on the public. These modelling tools require meteorological data as inputs for the calculation of atmospheric dispersion and radiological exposure in the near range of a nuclear installation due to accidental release of radioactive materials into the atmosphere. The dose estimation of the population living around nuclear facilities (such as reactors or nuclear laboratories) is important not only for emergency preparedness and response but also in safety analysis for showing that continuous releases during normal operation do not exceed the dose constrain and for confirmation that in the case of an accidental release the doses are lower than the relevant requirements.
In the last couple of years, the renewal of the meteorological measurement system of the KFKI Campus has been an important focus, which continues with the installation of a new SODAR meteorological instrument. This system is able to measure a number of meteorological parameters at various heights, including at ground level and at elevated heights of potential release points. By measuring meteorological parameters on a wider scale, the atmospheric dispersion calculations can be further refined.
The PhD student will join the work of the research group and carry out the following tasks:
· Study of the literature published regarding the existing techniques of automatic dispersion modelling and dose calculation systems.
· Investigation of the special requirements for meteorological measurements to use for the atmospheric dispersion modelling and dose assessment for the public in the near range of a nuclear installation.
· Examination of the installation and operation aspects of SODAR measurement system, calibration of the system, interpretation of results, development of automatic sampling and documentation of data.
· Development of methods for automatized computation of atmospheric dispersion and dose calculation.
· Demonstration of the applicability of the developed system, conducting dose calculations based on real measurement data for the population living in the vicinity of the KFKI Campus.
The PhD candidate will have the opportunity to participate in international conferences in the field of radiological measurements and atmospheric dispersion modelling. Professional support will be provided to the PhD candidate by the Radiation Protection Department of the HUN-REN Centre for Energy Research.
The applicant should have a proper level of knowledge and experience in the field of radiation protection, dosimetry and programming. The applicant should be able to work independently, have new ideas and sufficient knowledge of English to be able to conduct review of international literature in the field. Knowledge and experience in C or C++ programming language is an advantage.
