Over the coarse of my faculty studies in the field of physics I was introduced to plethora of different subjects. My background when it comes to Bachelors revolves around Medical Physics. There I was introduced in subjects and techniques that utilize concepts of modern physics and medicine. Here I did research and practical work in the field of RadioTherapy/Diagnostics where my B.Sc. was...
The most essential quantity that characterises the behaviour of a nuclear reactor is the neutron flux. Especially for the simulation of its time-dependent behaviour, which is crucial for the safety assessment, relatively coarse simplifications are often applied to make the neutron transport equation accessible to numerical calculations. The presented work introduces a high-fidelity,...
Neutron Depth Profiling (NDP) is a non-destructive, element-specific, high-resolution nuclear analytical technique, which is often used to probe concentration profiles of lithium, boron, nitrogen, helium, and several other light elements in different host materials. The N4DP instrument is located at the Prompt Gamma Activation Analysis (PGAA) beamline of Heinz Maier-Leibnitz Zentrum (MLZ),...
The construction of a new irradiation workbench is almost completed. Once finished, it will enable the conduct of quantitative neutron and photon experiments in the field of an americium-beryllium source. Therefore, different radiation field quantities, i.e. spectral fluence rates, fluence rates, ambient dose rate equivalents and directional dose rate equivalents, were determined for the...
In order to develop new applications and advanced technologies the worldwide scientific community requires very precise and highly reliable cross-section measurements. In this talk, I will present a measurement of neutron-induced (n,γ), (n,p), & (n,2n) reaction cross sections in the fast neutron energy region using FOTIA and PURNIMA facilities at BARC, India [1-2]. I will further talk about...
Neutron Activation Analysis (NAA) is a vital tool in the qualitative and quantitative measurement of elemental concentrations, with far-reaching applications in archaeology, geography, and agriculture, among others. This study applies NAA to quantitatively evaluate elemental concentrations in coffee samples and offers a comprehensive review of NAA — its operational principles and associated...
What happens to spent nuclear fuel? One promising future option might be fast (spectrum) reactors operated as a nuclear waste burners, i.e. fissioning plutonium and minor actinides (having half-lifes of tens of thousands of years) and essentially leaving fission products with storage times in the range of hundreds of years. One such fast reactor concept is a molten salt fast reactor (MSFR)....
The detection of radiation in the environment is crucial, often requiring compact and portable instruments. One effective method for detecting gamma-ray sources is through the use of a Compton gamma camera. Unlike Anger cameras, Compton gamma cameras employ source localization techniques based on Compton scattering kinematics. Various types of Compton gamma cameras have been developed,...
Chromium is a very relevant element regarding criticality safety in nuclear reactors because its presence in stainless steel, used as structural material. There are serious discrepancies between the different evaluated data of $^{50}$Cr and $^{53}$Cr neutron capture cross section which are not present in the corresponding estimated uncertainties. The Nuclear Energy Agency (NEA) opened an entry...
This abstract presents a detailed and comprehensive analysis of various aspects related to the Nigerian Research Reactor-1 (NIRR-1), including fuel burnup estimation, decommissioning strategies, radioactive waste management, and proliferation concerns. The study utilizes the WIMS-ANL computer code to assess the fuel burnup characteristics of both the existing Low-Enriched Uranium (LEU) fuel...
The Canberra GCW6023 well-type HPGe detector is one of the instruments at the Nuclear Security Department that is used to measure the gamma energy spectrum of low activity and typically small-sized environmental samples, e.g., slag, soil, or dust. Small samples in vials can be fitted into the 16 mm wide well providing high efficiency detection and consistent geometry. The detector is also...
