Radioactive Waste Management Coordination Unit (RAYK)

The Radioactive Waste Management Coordination Unit acting within the scope of Turkish Energy, Nuclear and Mineral Research Agency is responsible for the collection, acceptance, labelling, packaging and storage of radioactive waste arising from the use of radioactive materials in Türkiye. It is also responsible for implementing national and international legislation and monitoring technical, social, economic and policy-related studies.

These activities are carried out in accordance with the principles of protecting human health, the environment, areas beyond national borders and future generations; leaving the minimum possible burden to future generations; minimising waste generation; ensuring facility safety; and maintaining integrity between the stages of waste management.

The Radioactive Waste Management Facility, Türkiye's first and only licensed radioactive waste facility, was established in 1989.

!!!An appointment must be obtained via ray@tenmak.gov.tr before radioactive waste is delivered. !!!

Under the Regulation on the Management of Radioactive Waste and Spent Fuel, published in Official Gazette No. 32362 dated 7.11.2023, the person authorised for the activity that generated the waste must ensure that radioactive waste packages comply with the waste acceptance criteria.

Disused sealed sources may not be released into the environment or may not be stored finally by the authorised person. If return to the country or supplier of origin is not possible, they must be delivered to the radioactive waste facility. Sealed sources for which no reason is provided for the inability to return them to origin will not be accepted by the facility.

Delivery Conditions for the Temporary Storage of Radioactive Sources

If the volume of a package, device or similar load is less than 1 m³ and its weight is below 3 tonnes, it may be brought to the facility, after informing RAIT staff and making an appointment, without additional packaging or crane services.

Loads exceeding 1 m³ in volume or 3 tonnes in weight must be delivered secured within an additional package/container with an opening and closing lid that is watertight and resistant to outdoor weather conditions. Crane or handling services for unloading and stacking must be provided by the carrier.

Large or heavy loads must be unloaded at the location indicated by RAIT staff using a suitable crane hired by the carrier. A prior site inspection may be carried out if necessary.

Suitable clearances must be provided beneath the load to allow forklift forks to enter.

The surface dose rate must not exceed 30 µSv/h at any point. If this limit is exceeded, the carrier is responsible for providing additional packaging or shielding.

The load must contain a radioactive source above the exemption limits, be contaminated with radioactivity, or have itself become radioactive.

An official certificate, licence or measurement document demonstrating that this condition is met must be submitted to RAIT.

Loads that do not meet these conditions will not be accepted for temporary storage.

Waste Acceptance Criteria

Radioactive waste acceptance criteria have been determined taking into account the legislation of the Republic of Türkiye, international standards and recommendations, facility capacity and operating experience.

Acceptance by the facility is limited to radionuclides listed in the Table of Exemption Limits for Radioisotopes in Annex 4 to the Regulation on Authorisations for Radiation Facilities and Radiation Practices.

Sources below the activity and activity concentration limits in Annex 4 do not need to be delivered as radioactive waste. Although there is no upper activity limit for waste accepted by the facility, other requirements such as surface dose, criticality, gas generation and heat output must be met.

For packaged or unpackaged waste, the dose velocity on the surface of the package or original shielding must not exceed 30 µSv/h at any point. If this limit is exceeded, the waste producer and carrier must provide additional packaging or shielding.

Beta contamination must be below 0.4 Bq/cm².

Alpha contamination must be below 0.04 Bq/cm².

Surfaces exceeding these limits must be placed in a clean transport container.

With the exception of depleted uranium (DU) used for shielding in certified transport containers and nuclear compounds used for training and research, spent fuel, potentially critical fresh fuel and similar nuclear materials are not accepted by the facility. Acceptable nuclear compounds must be delivered within a containment system that ensures criticality safety and has been approved by the Nuclear Regulatory Authority (NDK).

The heat output of the waste must be at a level that will not damage the package or original shielding.

Generated gases must not cause damage such as swelling, explosion or corrosion.

Where pressure may increase, automatic pressure-regulating systems must be used and additional precautions must be taken for harmful gases.

Relevant analyses must be submitted to the facility before delivery.

Radioactive liquids containing chemical contamination must be kept in suitable chemical containers and shielded so as to comply with transport dose limits.

The waste form must not undergo a flammable or explosive reaction with air or water; chemical stability must be ensured by the waste producer.

Tesisimize teslim edilecek tüm radyoaktif atıklar için teslimden önce ilgili analizlerin tesisimize sunulması gerekmektedir.

Kimyasal kirlilik ihtiva eden radyoaktif sıvılar, ilgili kimyasalın şartlarına göre muhafaza edilmesinin yanında yüzey dozunun taşıma limitlerine çekilmesi için ayrıca zırhlanmalıdır.

Radyoaktif atık kimyasal madde içeriyorsa bu atık formunun hava ya da su ile doğrudan yanıcı, patlayıcı bir tepkimeye girmemesi gerekir. Atık üreticisi bu durumlarda atığın kimyasal kararlılığını sağlamalıdır.

Orta ve yüksek seviyeli radyoaktif atıkların paketlenmesi için yanmazlık sınıfı A kategorisi (alev almaz) olan malzeme kullanılmalıdır.

Düşük ve çok düşük seviyeli radyoaktif atıklar için en az yanmazlık sınıfı B2 sınıfı olmalı (kullanılan malzeme alev kaynağı uzaklaştırıldığında yanmaya devam etmemelidir).

Parlayıcılığı 65 0C altında olan hiçbir malzeme radyoaktif atıklarla birlikte kullanılmamalıdır.

Class A non-combustible material must be used for intermediate- and high-level waste.

At least Class B2 material must be used for low- and very-low-level waste.

Materials with a flash point below 65 °C must not be used with the waste.


Lightning conductors containing Ra-226 and Am-241 must be packaged separately; Ra-226 lightning conductors must be placed in a shielded crate meeting the 30 µSv/h limit.

Radioactive waste must not be packaged or transported together with, or side by side to, other classes of dangerous goods.

Other materials within the package must not be adversely affected by radiation or alter the characteristics of the waste.

Shielding or packaging must not make it impossible to determine the number of sources or to access the source.

Sealed sources must be delivered intact in their transport container or device; sources whose integrity has been compromised must be provided with additional shielding.

Packages must be secured during transport using pallets, chocks, ropes, ratchet straps or similar means.

The package type and transport index must be indicated by a radioactive material label compliant with the applicable legislation.

Materials contaminated with NORM-TENORM or artificial radioisotopes weighing 3 tonnes or more, including packaging and securing elements, must be delivered in an unused and undamaged ISO 20-foot or ISO 40-foot container. Contaminated materials below 3 tonnes must be transported in leak-tight, top-opening, robust and weather-resistant packages with suitable clearances for forklift forks.

For container deliveries, four new Twistlocks and two Bridge Fittings must be provided for each container; installation must be carried out on the facility site by the organisation delivering the waste. The carrier is responsible for the costs of unloading, stacking, crane services and competent personnel.

No other waste, such as bare or sealed sources, lightning conductors, radioactive gauges or compasses, may be placed in a container or package containing contaminated scrap. A chargeable specialist service will be applied in cases of incomplete declaration or incorrect classification.

Where 10 or more medical generators are delivered at one time, they must be wrapped or secured on robust pallets so as to prevent overturning.

Labelling, packaging and transport must comply with the applicable legislation and Guideline RSGD-KLV-035.


Waste that does not comply with the conditions may, following assessment by RAIT specialists, be placed in temporary storage or returned without acceptance. Where temporary storage is used, a service application must be submitted and the waste will be stored for a fee until the conditions are met.

Packages arriving at the facility are checked for compliance with legislative, labelling, dose-rate, contamination, identification, stacking, internal arrangement and strength requirements. Measurements are made using calibrated instruments, physical conditions are assessed by visual inspection, and matters requiring certification are assessed on the basis of the documents submitted.

Non-compliant packages may, within the facility's capabilities, be brought into compliance through additional shielding, packaging, labelling, measurement or identification. A specialist fee starting from one specialist/one day is charged for these operations. If this is not possible, temporary storage will be applied or the waste will be returned; any return will be notified to the Nuclear Regulatory Authority (NDK).

Frequently Asked Questions on Radioactive Waste Management

Applications are submitted through the e-Government Gateway using an individual's login. Any person who has information about the waste to be delivered may submit the application, irrespective of their authority within the organisation.

A charge is generated after the application. Payment is made to Ziraat Bank using the charge reference number; cash payments are not accepted.

Persons or organisations without a radioactive material transport licence may not carry out transport. Carriers licensed by the Nuclear Regulatory Authority (NDK) must be used.

Waste is accepted together with its transport packaging. For devices containing a source, the entire device is delivered; the source is not removed with the remaining parts returned.

X-ray tubes and X-ray devices are not accepted as radioactive waste because they do not contain radioactive sources. Chemical waste procedures must be carried out in accordance with environmental legislation and the Nuclear Regulatory Authority (NDK) must be informed.

TENMAK does not remove lightning conductors. A waste delivery application may be submitted for lightning conductors that have already been removed; licensed organisations must be engaged for removal and transport.

A copy of the transport licence, the application form, the radioactivity analysis form and other documents depending on the type of waste are required. For details, please write to ray@tenmak.gov.tr.

When waste information is submitted by formal petition, fee information is provided by official letter; this letter may be treated as a quotation. TENMAK does not submit bids directly in tenders.

Radioactive waste that has been accepted cannot be reused and is not returned.

Waste weighing more than 3 tonnes including its packaging must be delivered in a 20-foot ISO container. The carrier is responsible for providing crane services for unloading.

TENMAK does not provide radioactive material or waste transport services.
