URANIUM EXPLORATION AND MINING ACTIVITIES OF TURKEY AS A NEWCOMER S. GEZER Ministry of Energy and Natural Resources, Ankara, Turkey Countries embarking on a nuclear power programme are referred to as a ‘newcomer’ need to ensure that the development of their legal, regulatory and support infrastructure is aligned with the construction of the nuclear power plant itself. This is done to ensure that the programme proceeds in a safe, secure and sustainable way. Through several initiatives, the transfer of information and knowledge is required from States with extensive experience in uranium mining and production to so-called newcomers to the sector. Growing demand from a much-anticipated nuclear power renaissance and the subsequent potential significant increase in the cost for nuclear fuel have recently spurred greater investment in uranium exploration in an increasing number of countries. Nuclear power is an inevitable option for Turkey to meet energy security. Turkey has distinctly progressing its nuclear energy program in nuclear milestones. As being aware of that uranium mining and activities would be a significant role in supporting energy security by realizing domestic nuclear energy fuel for the nuclear power plant projects. This paper wholly provides the recent uranium exploration activities, drilling efforts, identified conventional resources, environmental activities and regulatory regime of Turkey with the details. 1. BACKGROUND: URANIUM FOR NUCLEAR POWER Access to uranium resources are an integral part of the nuclear fuel cycle. To increase the capability of interested Member States in planning and policy making on uranium production, the IAEA works together with the OECD Nuclear Energy Agency (NEA) to collect and provide information on uranium resources, production and demand. With uranium production ready to expand to new countries, efforts are being made to develop transparent and well-regulated operations similar to those already established elsewhere to minimize potential environmental and local health impacts [1]. The general energy policy of Turkey focuses on the supply of secure, sustainable and affordable energy by diversifying energy supply routes and source countries, promoting usage of domestic resources and increasing the energy efficiency and renewable energy usage in order to decrease the energy intensity of production. Nuclear energy is considered an option within Turkey for diversification of electricity generation and also for reduction of greenhouse gas emissions from the energy sector. The Akkuyu nuclear power plant project started with an Inter-Government Agreement between Turkey and the Russian Federation for construction and operation of 4 WWER-1200 reactors in Akkuyu site, which is situated on the Mediterranean coast of Turkey. Akkuyu NPP Project Company (PC) has also submitted Site Parameter Report (SPR) which is one of the mandatory documents before construction license application to Turkish Atomic Energy Authority (TAEK). The SPR has been approved by TAEK in February 2017 and application for construction licence was made by PC in March 2017 to TAEK. A comprehensive environmental impact assessment report was prepared by the PC, taking into consideration the requests from a wide range of stakeholders. The project was approved in December 2014. Energy Market Regulatory Authority (EMRA) had granted an electricity generation licence in June 2016 which will form the basis of 152 the Power Purchase Agreement (PPA). The revised site parameters’ report was approved by the Turkish Atomic Energy Authority on February 2017 and granted a limited work permit for construction of non- nuclear safety related facilities in October 2017. On the other hand, PC submitted Environmental Impact Assessment (EIA) Report to Ministry of Environment and Urbanism (MoEU) on 6th December 2013. An affirmative decision was given on 1st December 2014. Besides, PC obtained an Electricity Generation License for 49 years from Energy Market Regulatory Authority (EMRA) on 15th June 2017. Moreover, PC and state-owned Turkish Electricity Wholesale and Contracting Company (TETAS) signed a Power Purchase Agreement (PPA) on 30th December 2017. On 30 March 2018, PC obtained construction license. On 3 April 2018, it has formally launched construction of 1st unit of Akkuyu NPP with the pouring of concrete for the sub-base foundation of the nuclear island. The other nuclear power plant project IGA which includes construction and operation of 4 units of ATMEA- 1 reactors in the Sinop site and an Inter-Government Agreement for the development of nuclear industry in Turkey was signed between Turkey and Japan in 2013 and ratified in 2015. The second NPP project (Sinop Project) will be conducted by a Turkish-French-Japanese Consortium and as a Turkish partner is state-owned Turkish Electricity Generation Company (EUAS). In the context of Sinop Project, feasibility studies are ongoing for verification of site suitability and development of financial scheme. It is expected that feasibility studies will be completed within the year of 2018. After the feasibility study, Sinop Project Company (SPC) will be established. On the other hand, EUAS International Incorporated Cell Company (EUAS ICC) was established in 2016 as an international nuclear private company of EUAS and it will have up to 49% of share in the SPC on behalf of EUAS. In the context of Sinop Project, feasibility studies are ongoing for verification of site suitability and development of financial scheme. It is expected that feasibility studies will be completed within the year of 2018. After the feasibility study, Sinop Project Company (SPC) will be established. The strategic goal of nuclear energy usage in Turkey is mentioned in the strategic plan of MENR under the goal for optimum energy resource diversity. Turkey has high energy imports and fossil fuel dependency which makes it vulnerable to external fluctuations in global markets. Nuclear energy is considered as one of the options, together with local resources and renewable energy, to strengthen the energy sector in Turkey. Exploration for radioactive minerals has been conducted in Turkey since the 1950s. Development requires further studies to define the feasibility to start production [2]. As a result, the strategic plan includes a target for reserve determination of radioactive minerals, together with their respective feasibility studies for usage in the nuclear energy sector [3]. 2. DESCRIPTION 2.1. General Directorate of Mineral Research and Exploration (MTA) Uranium exploration in Turkey began in 1956–1957 and was directed towards the discovery of vein type deposits in crystalline terrain, such as acidic igneous and metamorphic rocks. As a result of these activities, some pitchblende mineralization was found but these occurrences were not determined to be economic deposits. Since 1960, studies have been conducted on the sedimentary rocks surrounding the crystalline rock and some small orebodies containing autunite and torbernite mineralization have been found in different parts of the country. In the mid-1970s, the first ‘hidden’ uranium deposit with black ore, lying below the water table, was found in the Koprubaşı area of Manisa. As a result of these exploration activities, a total of 9129 t U3O8 (7740 tU) of in situ resources were identified in the Manisa– Köprübaşı (2852 t U3O8; 2419 tU), Uşak–Eşme (490 t U3O8; 415 tU), Aydın–Koçarlı (208 t U3O8; 176 tU), Aydın–Söke (1729 t U3O8; 1466 tU) and Yozgat–Sorgun (3850 t U3O8; 3265 tU) regions. 153 2.2. Eti Mine Works General management (Eti Maden) State-owned organization Eti Maden is responsible for a total of six uranium mine sites with known uranium resources. Geological exploration has been performed by MTA at these sites in the past. In 1960–1980, uranium exploration was undertaken by aerial prospecting, general and detailed prospecting on-site, geological mapping studies and drilling activities. These uranium sites were transferred to Eti Maden management as possible mines which can be operated by the State under Law No. 2840 on the Operation of Boron Salts, Trona and Asphaltite Mines and Nuclear Energy Raw Materials (10 June 1983). 2.3. Recent and ongoing uranium exploration and mine development activities 2.3.1. General Directorate of Mineral Research and Exploration (MTA) In 2012, granite, acidic igneous and sedimentary rocks around Manisa, Denizli and Aydın (an area of approximately 5000 km2) were explored for radioactive raw materials. Exploration for radioactive raw materials was also performed at sites licensed by MTA at Manisa, Uşak and Nevşehir. In 2013, granite, acidic igneous and sedimentary rocks around Aydın and Denizli (an area of approximately 5000 km2) were explored for radioactive raw materials. Exploration for radioactive raw materials was also performed at sites licensed by MTA at Manisa, Uşak and Nevşehir. In 2014, exploration for radioactive raw materials was conducted in sites licensed by MTA at Manisa, Uşak and Nevşehir. In 2015, exploration for radioactive raw materials was conducted in sites licensed by MTA inside Manisa and Nevşehir [4]. 2.3.2. Private sector exploration Adur, a wholly-owned subsidiary of Anatolia Energy, a Turkish uranium exploration company with current and active drilling programmes at the Temrezli and Sefaatli uranium sites, has carried out exploration and resource evaluation drilling with a total of 206 drill holes completed for a total drill advance of over 26 000 m since 2011 at both Şefaatli and Temrezli sites.
