In this study, in order to understand the possible use of PMMA in radioactive waste management as a solidifying agent, radiation stability of the PMMA was studied by gamma irradiations at two different dose rates of 1485 and 82.8 Gy/h. The total dose of irradiation was up to 523 kGy. Degradation nature was tested by studying the changes in mechanical and thermal properties with rate and total dose of irradiation. Ultimate tensile strength and toughness first increased and then decreased with total irradiation dose. Half value dose (HVD) for elongation was 148 kGy and it was 178 kGy for tensile strength at the dose rate of 1485 Gy/h. Half value dose was found from the extrapolation of experimental data as 228 kGy for elongation and 205 kGy for tensile strength at the dose rate of 82.8 Gy/h. The FTIR spectral analysis showed depolymerization degradation of polymer with irradiation. It was concluded from experimental results that PMMA can be used for embedding radioactive wastes.

Use of poly(methyl methacrylate) in radioactive waste management: II. Monte Carlo simulations Ozdemir, Tonguc; Usanmaz, Ali (Elsevier BV, 2009-11-01) Radioactive waste is generated from the nuclear applications and it should properly be managed in a radioactive waste management system. Different methods are available for treatment and conditioning of radioactive waste. Polymers can be used in the radioactive waste management as an embedding matrix. Poly(methyl methacrylate (PMMA) is a possible candidate material that can be used in the low level radioactive waste management. In this study, based on total resistible dose for PMMA, maximum waste activity t...
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...
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...
The effect of soluble boron on the burnup at different enrichments and assemblies Gündüz, Güngör; Ajwah, Yousef (Elsevier BV, 1989-5) The effect of boron on the optimum burnup was investigated at different assemblies for enriched fuels. As the enrichment increases, an alteration in the assembly type is needed for the optimum specific power. This alteration can be made at lower enrichments due to the presence of boron. The optimum specific power is shifted toward the high enrichment fuels when the assembly number is increased. If a fuel of high enrichment is first burnt in a highly hardened neutron spectrum and later in a softer spectrum t...
Effect of Carboxy Methyl Cellulose and Determination of Pore Throat Criteria for Water-based Drilling Fluids Kök, Mustafa Verşan (Informa UK Limited, 2009-01-01) In this research, the effect of carboxy methyl cellulose (CMC) on the rheological properties of two different water-based drilling fluids was studied. It was observed that the fluid loss decreased as CMC concentration increased, but the rate of decrease was too low to notice after 1 gr. CMC. It was also observed that shear stress increased as the CMC concentration increased. Experimentally, it was observed that 1 gr. CMC/350 ml of drilling fluid slurry is sufficiently appropriate for optimum rheological eff...
