Radioactive waste is generated from the nuclear applications and it should properly be managed according to the regulations set by the regulatory authority. Poly(carbonate urethane) and poly (bisphenol a-co-epichlorohydrin) are radiation-resistant polymers and they are possible candidate materials that can be used in the radioactive waste management. In this study, maximum allowable waste activity that can be embedded into these polymers and dose rate distribution of the waste drum (containing waste and the polymer matrix) were found via Monte Carlo simulations. The change of mechanical properties of above-mentioned polymers was simulated and their variations within the waste drum were determined for 15, 30 and 300 years after embedding.

Modeling the effect of dose rate and time on crosslinking and scission in irradiated polyethylene Sargın, Irmak; Beckman, S. P. (2020-06-01) The insulation around the electrical cabling in nuclear power plants is frequently made of ethylene-propylene rubber and crosslinked polyethylene that is subjected to low levels of environmental stressors and radiation over the duration of their decades long service life. For the purpose of maintenance and reactor recertification, it is necessary to develop a non-destructive approach to determine the degree of damage the insulation has sustained. Accelerated aging experiments are used to develop these metho...
Degradation of poly(bisphenol-a-epichlorohydrin) by gamma irradiation Ozdemir, Tonguc; Usanmaz, Ali (Elsevier BV, 2008-06-01) In this study, radiation stability of poly(bisphenol-a-epichloroliydrin) (PBEH) was studied via gamma irradiations at two different dose rates of 1540 and 82.8 Gy/h, in order to understand the possible use of PBEH in radioactive waste management as a solidifying agent. The total dose of irradiation was up to 2150kGy. Degradation nature was tested by studying the changes in mechanical and thermal properties with the change of dose rate and total dose of irradiation. Tensile strength at yield was increased fi...
Co-60 gamma irradiation influences on physical, chemical and electrical characteristics of HfO2/Si thin films KAYA, ŞENOL; Yıldız, İlker; LÖK, RAMAZAN; YILMAZ, ERCAN (Elsevier BV, 2018-09-01) Co-60 gamma irradiation effects on physical, chemical and electrical characteristics of HfO2/Si thin films have been investigated in details. The variations on the crystallographic structure and surface morphology of the films under irradiation exposures were characterized by using X-ray diffractions (XRD) and Atomic Force Microscopy (AFM) measurements. The irradiation influences on the electrochemical structure of the films were analyzed by X-ray photoelectron spectroscopy (XPS) for various depths of the H...
Space radiation environment and radiation hardness assurance tests of electronic components to be used in space missions Amutkan, Özge; Esendemir, Akif; Department of Physics (2010) Space radiation is significantly harmful to electronic Components. The operating time, duration and orbit of the space mission are affected by the characteristic of the radiation environment. The aging and the performance of the electronic components are modified by radiation. The performance of the space systems such as electronic units, sensors, power and power subsystem units, batteries, payload equipments, communication units, remote sensing instruments, data handling units, externally located units, an...
Development of a radioecological model for accidental release of radionuclides Unver, O.; Kocar, C.; Tuncel, G. (Carl Hanser Verlag, 2020-10-01) A dynamic radioecological model was developed to estimate radiation doses and stochastic health risks due to atmospheric releases in case of a nuclear reactor accident. Activities in some foodstuffs, feedstuffs and grass, and doses from different pathways for age groups and stochastic risks can be calculated by the model. Dynamic features include food harvesting, sowing times, feeding regimes, and the growing up of a person. The model can be coupled to any atmospheric dispersion model which can calculate ra...
