Turkey intends to build and operate twelve nuclear reactor units in the next ten years; therefore, the regulatory body of Turkey needs a systematic, comprehensive, and up-to-date seismic hazard assessment (SHA) guideline that is applicable for all candidate designs and compatible with the international legislative structures. To facilitate towards this goal, current SHA practice and related regulatory requirements of the leading countries, international organizations, and Turkey are evaluated and compared by focusing on the critical aspects of seismic source and ground motion characterization. Discussions are qualitatively supported by the good practice implemented in the previous nuclear power plant (NPP) projects and the lessons learned from the past experiences. Considerable differences in practical applications and regulatory requirements have been identified in the definition of spatial scales, capable fault terminology, estimation of magnitude recurrence parameters, considered minimum magnitude, assigned maximum magnitude, selection of ground motion models, and truncation of ground motion variability. Quantitative comparisons in terms of the hazard curves are provided to further underline the range and extend of the differences in international approaches for a reference NPP site. Analysis results revealed that the selection and level of truncation for the uncertainty of ground motion models and the possibility of existence for a relatively small capable fault in near region scale have a higher impact (up to 2-fold increase) on the design-basis ground motion, compared to the other parameters. Tangible recommendations are provided for Turkey’s and other embarking countries’ future SHA guidelines and applications based on the comparison results.

A Sensitivity study for probabilictic seismic hazard assessment of Sinop nuclear power plant site Yılar, Erkan; Gülerce, Zeynep; Kaymakcı, Nuretdin; Department of Earthquake Studies (2014) Based on the studies conducted for more than 40 years, Sinop is chosen as one of the three most convenient places in Turkey to construct a Nuclear Power Plant (NPP). The objective of this study is to evaluate the sensitivity of the design ground motions for Sinop NPP Site to the seismic source characterization and ground motion prediction models within the probabilistic seismic hazard assessment (PSHA) framework. This study introduces significant improvements over the previous seismic hazard studies conduct...
Turkey’s energy system development: Linking an energy supply model with an industrial simulation model and solving it iteratively Gungor, Gorkem; Sarı, Ramazan (2018-01-01) Turkey is in the progress to include nuclear energy to its electricity generation capacity. The energy modelling studies for Turkey mainly focus on usage of renewable energy and local fossil fuels and include nuclear power plants (NPP) only with their electricity generation capacities without taking into consideration the front- and back-ends of the nuclear fuel cycle. This study takes into consideration the life cycle assessment (LCA) of nuclear energy based on optimisation of energy system costs and usage...
Comparison of large scale solar PV (photovoltaic) and nuclear power plant investments in an emerging market Karaveli, Abdullah Bugrahan; Soytaş, Uğur; Akınoğlu, Bülent Gültekin (2015-05-01) We examine and compare economic feasibilities and environmental effects of two energy investments options in Turkey: a NE-PP (nuclear power plant) in Mersin province on the Mediterranean coast and a large scale photovoltaic solar energy power plant (PV-PP) to be built in a governmentally reserved land area in mid-south Anatolia, namely Karapinar Energy Specialized Industrial Zone (Karapinar-ESIZ). Total installed power of both plants is taken to be 4800 MW, which is the contracted value for the four units o...
Investigation of Large Scale Slope Failure Mechanisms and Numerical Modeling for the Safe Design of Slopes in a Lignite Mine Tutluoglu, LEVEND; Karpuz, Celal (2008-07-24) With about 9.3 billion tons of reserve, lignite is a major source for energy production in Turkey. Turkish Coal Enterprises (TKI) produces about 60% of the yearly lignite production capacity. Can Surface Lignite Mine which is planned to produce approximately 2.5 million tons of 3000 kcal/kg coal, will be one of the main production areas of TKI. Possibility of large scale slope failures and their negative effects on mining operations in large Can Lignite Surface Mine on the northwestern Turkey were the major...
Proposal for an irradiation facility at the TAEK SANAEM Proton Accelerator Facility Demirköz, Melahat Bilge; KIZILÖREN, DİLEK; Apsimon, R. (Elsevier BV, 2013-12-01) Turkish Atomic Energy Authority's (TAEK's) Proton Accelerator Facility in Ankara, Turkey, has been inaugurated in May 2012 and is under the process of being certified for commercial radio-isotope production. Three of the four arms of the 30 MeV cyclotron are being used for radio-isotope production, while the fourth is foreseen for research and development of novel ideas and methods. The cyclotron can vary the beam current between 12 mu A and 1.2 mA, sufficient for irradiation tests for semiconductor materia...
