In this study, radiological impacts of atmospheric releases and aquatic discharges due to the routine (normal) operation of Metsamor (Armenia) Nuclear Power Plant (NPP) on the public living in Province of Iğdır (Turkey) were investigated by two approaches, (1) using PC CREAM 08 software and (2) using the method provided in the IAEA SRS 19 safety report (International Atomic Energy Agency). Based on the obtained results, estimated public doses in the region by both approaches comply with 0.1 mSv/year dose constraint (NDK, 2019). The results showed that the main exposure pathways for the public based on maximum public doses in PC CREAM 08 approach are food consumption, external gamma and fish consumption due to atmospheric releases and aquatic discharges whereas food consumption and fish consumption are the main exposure pathways for IAEA SRS 19 approach. In PC CREAM 08 approach, the main dose contributing radionuclides were obtained as 14C, 41Ar, 3H, 131I and 137Cs for atmospheric releases, and 137Cs, 134Cs and 3H for aquatic discharges. On the other hand, the main dose contributing radionuclides were obtained as 137Cs, 134Cs, 90Sr and 131I for atmospheric releases, and 137Cs, 134Cs and 90Sr for aquatic discharges for IAEA SRS 19 approach. As a conclusion, the health risk on the public living in Province of Iğdır due to routine operation of Metsamor NPP was determined as so small (the probability of total cancer risk for an individual is 7.67E-08 in PC CREAM approach and 5.40E-07 in IAEA SRS 19 approach).

The effect of reed beds on wave attenuation and suspended sediment concentration Oğuz, Elif; Koroglu, Aysun; Kabdaşlı, Mehmet Sedat (Coastal Education and Research Foundation, 2013-01-01) The effect of emergent and submerged vegetation on uniform and oscillatory flow conditions has been intensively studied by researchers in the last two decades. It has been determined that vegetation affects wave characteristics and cause wave attenuation especially in shallow waters where wave orbitals are in interaction with vegetation. Consequently they affect sediment deposition and resuspension acting as a sink. The aim of this study is to determine wave attenuation due to vegetation, and to identify th...
The response of periphyton and submerged macrophytes to nitrogen and phosphorus loading in shallow warm lakes: a mesocosm experiment Özkan, Korhan; Johansson, Liselotte S.; Beklioğlu, Meryem (2010-02-01) 1. Recent experimental and field studies on temperate shallow lakes indicate that nitrogen may play a greater role in their functioning than previously thought. Several studies document that abundance and richness of submerged macrophytes, both central in shallow lake ecology, may decrease with increasing nitrogen loading, especially at high phosphorus levels. However, the role of nitrogen in warm lakes with fluctuating water regimes remains to be described in detail.
The Effects of Implementing Different Ground-motionLogic-tree Frameworks on Seismic Risk Assessment Ay, Bekir Özer (null; 2018-06-21) This study investigates the link between probabilistic seismic hazard assessment and corresponding loss estimations by using different ground-motion logic-tree frameworks from reliable large scale seismic hazard projects as well as the logic-tree framework established in this study. The predictive models selected for these logic trees are expected to represent the center, body and range of ground-motion intensity measure estimates. Regarding with the hazard component of risk assessment, the ground motion in...
A comprehensive evaluation of possible eutrophication control methods for Keban dam reservoir with special emphasis on pre-dam construction Karul, C; Soyupak, S; Tuncer, A; Mukhallalati, L; Cilesiz, AF (1997-05-01) This study evaluates the available eutrophication control techniques that could be applied in Keban Dam Reservoir. A limited reduction of phosphorous was shown to be achieved by pre-dam construction on the major nutrient source, Murat River. Biomanipulation was evaluated as an ineffective method. A performed analysis has shown that only a drainage basin management program may decrease the phosphorous loading to the extent desired.
The chemical composition of Black Sea suspended particulate organic matter pyrolysis GC MS as a complementary tool to traditional oceanographic analyses Coban Yıldız, Yesim; Chiavari, D; Fabbri, D; Yılmaz, Ayşen; Tuğrul, Süleyman (Elsevier BV, 2000-03-01) A “traditional” description of the abundance and chemical composition of suspended particulate organic matter (POM) in open and coastal waters of the southern Black Sea in June 1996 has been confirmed and extended by pyrolysis–gas chromatography/mass spectrometry (Py-GC/MS) analyses. Py-GC/MS provided depth profiles of the relative concentrations of twenty three marker compounds characteristic of chlorophylls (CHL), lipids, carbohydrates (CBH) and proteins produced by thermal degradation of the POM retained...
