In this study, both pure fusion blanket and fusion-fission (hybrid) reactor blanket performance were investigated and discussed separately in two phases. In the first phase, a Monte Carlo radiation damage analysis has been performed for stainless steel (SS304, SS316, and oxide dispersion strengthened (ODS)), molybdenum, vanadium, and tungsten as the first wall (FW) materials, in combination with selected tritium breeders. The main technical parameters for fusion reactors, such as tritium breeding ratio, fusion energy multiplication factor (M), displacement per atom (DPA), and gas production (He, H) have been evaluated. All numerical calculations have been carried out in spherical geometry with MCNP6 code package using continuous energy cross-sections from the ENDF/B-VIII.0 library, except DPA calculations. Instead of the ENDF/B-VIII.0 library, the 30-group CLAW-IV library was employed for DPA calculations. Structural material selection for the FW respect to radiation damage limits and reactor performance for energy production and tritium has been concluded. Conventional thermal reactors, such as light water reactors andCanada Deuterium Uranium (CANDU) reactors are producing substantial quantities of transuranic elements, which represent serious nuisance and permanent hazard potential. On the other hand, they become fissionable material under high energetic fusion neutron irradiation and multiply the fusion energy. In the second phase, the investigations are extended to the incineration of minor actinides (MA) in the fusion-fission (hybrid) mode. The transmutation history of MA nuclear waste is included. MA are added into the first zone of the coolant in TRi-structural ISOtropic particle TRISO particles with a volume fraction of 6%. The transformation scenario for all MA by SS 304 steel FW is practically the same as with the ODS FW.

Mechanistic questions regarding kidney stone formation have led researchers to look for the presence of trace elements. Neutron activation analysis is able to identify elements at parts-per-million concentrations. Four different types of kidney stones were irradiated with thermal neutrons to produce radioisotopes. Gamma spectroscopy of samples at different counting times was used to reduce identification errors by correlating results with the half-life of identified elements. For more precise identification, Monte Carlo simulation was used to cross-check the identification process. The simulation showed promising results that could lead to fast and accurate identification of trace elements as the simulation code is improved. Sodium (Na), potassium (K), calcium (Ca), bromine (Br), samarium (Sm), zinc (Zn), cadmium (Cd), ytterbium (Yb), gold (Au), cobalt (Co), and manganese (Mn) were identified as being present in the stones, by both the experimentally measured gamma spectrum and the simulation. Among these, Ca, Br, and Zn were found to be of potential clinical relevance via a literature review. Concentrations of the elements were compared to those noted in the literature. For uric acid stones, a correlation with the literature was found for Zn and Ca. A negative correlation was found between Zn and Br for non-uric acid stones. More samples are needed to test for statistical significance.

Aerosoller doğal süreçler ya da insan faaliyetleri sonucunda atmosfere karışmakta ve iklim şartlarından insan sağlığına kadar birçok faktör üzerinde etkili olmaktadır. Bu çalışmada 1 Ocak 2019 ve 19 Nisan 2021 tarihleri arasında aerosol optik derinlik görüntüsü alınabilen toplam 292 günlük Moderate Resolution Imaging Spectroradiometer uncertainty ve 0.55 μm verileri kullanılmıştır. Salgının etkisinin Türkiye’de ciddi anlamda hissedildiği 2020 Mart ayının 15. günü analizlerde salgın öncesi ve salgın süreci ayrım günü olarak belirlenmiştir. Türkiye’nin önemli sanayi kentleri arasında yer alan Karabük ve Karadeniz Ereğlisi araştırmanın alan kapsamını, bu şehirlerde Covid-19 salgın sürecinin aerosol optik derinliği üzerindeki etkisi ise konu kapsamını oluşturmaktadır. Araştırmanın amacı salgın sürecinin aerosol optik derinliği üzerindeki etkisini ortaya koymaktır. Yapılan analizler sonucunda genel olarak uncertainty aerosol optik derinlik değerlerinde mevsimsel bir döngünün var olduğu tespit edilmiştir. Uncertainty aerosol optik derinliğinin hem genel ortalama hem de Covid 19 salgın süreci öncesi ve salgın sürecinde Karabük şehrinde Ereğli’ye oranla daha fazla olduğu görülmektedir. Ayrıca her iki çalışma alanında da aerosol optik derinlik değerlerinde salgın sürecindeki 149 günlük dönemde, salgın öncesindeki 143 günlük döneme göre düşüş yaşanmıştır. 0.55 μm aerosol optik derinlik verileri ile yapılan analizlerde, uncertainty verilerine paralel olarak Covid 19 sürecinde azalma dikkat çekmekte ve azalma miktarı artmaktadır. Karabük Kardemir 1 istasyonundan alınan partikül madde 10 değerleri ile analiz sonuçları karşılaştırıldığında mevsimsel döngü bakımından benzerlik görülmekle birlikte en yüksek değerler sonbahar sonu ve kış başlarında ortaya çıkmaktadır. Ayrıca salgın süreci ile birlikte partikül madde 10 miktarında %32 gibi önemli oranda düşüş yaşanmıştır. Bu düşüşte salgın süreciyle birlikte sanayi de dahil olmak üzere insan faaliyetlerinde meydana gelen yavaşlamanın etkisi büyüktür.
