Romania Builds on Bulgaria’s Experience in Developing a National Radioactive Waste Repository

infocenter — Fri, 30 Jan 2026 14:58:40 +0000

Cooperation with SE Radioactive Waste focuses on the construction of a national repository in Romania at a key stage of the project
From 26 to 30 January 2026, the State Enterprise Radioactive Waste hosted for a second time a working visit by the senior management of Romania’s Nuclear and Radioactive Waste Agency. The delegation—comprising President Mihaita Gaina, Vice President Ramona Popescu, and Senior Advisor Monica Carmen—took part in an intensive five-day exchange of knowledge and good practices with their Bulgarian counterparts. This visit, the second following the initial one in June 2021, underscored the maturity and strategic importance of the partnership between the two national operators, particularly as the Romanian project enters an active phase for the construction of a near-surface repository.
During the visit, Romanian specialists received a comprehensive overview of the full technological cycle of radioactive waste management in Bulgaria. They toured key facilities, including the Turbine Hall, the Measurement and Clearance System, the Plasma Melting Facility (during an operational campaign), the Size Reduction and Decontamination Workshop, the Site and Workshop for the Production of Reinforced-Concrete Containers, the “Radioactive Waste – Kozloduy” Specialized Unit, and the National Repository for Low- and Intermediate-Level Radioactive Waste (NR LILW).
The programme featured in-depth technical sessions in which experts from SE Radioactive Waste presented their developments and experience across several critical areas:
• Automated radioactive waste traceability system;
• Management of materials and waste arising from decommissioning activities, with a focus on achievements, lessons learned, and next steps;
• Core systems and components ensuring the safe disposal of radioactive waste;
• Information policy and public communication, including concrete mechanisms for turning concepts into successful programmes.
“We are very grateful for the opportunity to share the experience of SE Radioactive Waste,” said Vice President Ramona Popescu, “as we are now beginning construction of the same type of repository in Romania and the concepts are very similar. This is why we chose to draw on your experience. We are impressed by the wide range of activities and were pleased to see the Plasma Melting Facility in operation—waste minimisation is a priority for us, and you already have solid experience. We also hold the Information Centre in very high regard for its professionalism in terms of projects, products, and public relations.”
President Mihaita Gaina emphasised the strategic dimension of the cooperation: “The relationship we are building with you is extremely important. We hope it has already become a permanent channel for a productive future. The most important part for us was the visit to the National Repository and the impressive progress achieved there. In the near future, we would be pleased to return the visit, as we rely on your expertise for the technical assessment of our project, whose specifications are almost identical.”
In the context of the visit (since August 2025 Romania has been in an active phase of site selection for its national repository, with a design contract already signed), the practical experience and accumulated expertise of SE Radioactive Waste – as an operator with a completed facility—has become an invaluable resource for the Romanian partners. This second, more focused and in-depth visit strengthened mutual trust and respect and outlined clear prospects for continued cooperation. The partnership is already evolving from a general exchange of information into concrete, project-based support between the two neighbouring countries, aimed at ensuring the highest standards of nuclear safety in the region.

Experts from the Dutch nuclear regulator (Authority for Nuclear Safety and Radiation Protection, ANVS) visited the Plasma Melting Facility

infocenter — Tue, 13 Jan 2026 13:53:28 +0000

The facility is of much interest to the international professional community

On 12 and 13 January 2026, following an expressed interest by the Authority for Nuclear Safety and Radiation Protection (ANVS) of the Netherlands in the Plasma Melting Facility, State Enterprise Radioactive Waste (SERAW) hosted a visit by a team of five experts from the Dutch regulatory authority.
On the first day of the two-day visit, the Deputy Executive Director for Radioactive Waste Management, Georgi Razlozhki, and the Head of Plasma Melting Section, Iliyan Dimitrov, familiarized the specialists in detail with the technical features of the facility for treatment and conditioning of radioactive waste.
During the second day, the delegation visited the facility on site. Following a scheduled maintenance, the facility is now being made ready to start its ninth operational campaign. Since the first operational campaign, which began at the end of 2018, more than 6,300 cubic metres of radioactive waste have been treated. Over the most recent campaign, a total of 1,375 cubic metres of radioactive waste was treated, representing a record volume to date.
“Your assistance is extremely valuable to us. For us, this was a highly beneficial visit. We are impressed with the organisation, the comprehensive information provided by you, and your readiness to share your experience with us. We learned a great deal.”, so commented the participants in the visit.

The construction of a radioactive waste treatment and conditioning facility capable of achieving a high-volume reduction factor is among the most significant projects implemented through the support of the Kozloduy International Decommissioning Support Fund (KIDSF). The Plasma Melting Facility represents a unique technology, and through its capabilities of feeding various combinations of radioactive waste, it achieves a very high volume reduction factor that is difficult to achieve with other technologies. This ensures full compliance with all radioactive waste management principles, in particular, the disposal of minimal quantities and the avoidance of burdening the generations to come with the care of radioactive waste generated today.
The project was implemented by an international consortium. The facility was constructed to support the safe decommissioning of Units 1 to 4 of the Kozloduy Nuclear Power Plant, a responsibility entrusted to State Enterprise Radioactive Waste. In addition to waste from the units under decommissioning, the facility also treats radioactive waste generated from the operation of Units 5 and 6 of the Kozloduy Nuclear Power Plant.

An Automated Information System for Control of Technological Processes and Traceability of RAW is the Knowledge Product for 2024

infocenter — Fri, 07 Mar 2025 14:47:59 +0000

State Enterprise Radioactive Waste (SERAW) shared with the international professional community its experience in developing and applying a specialist waste traceability software in the process of RAW management. Pursuant to COUNCIL REGULATION (Euratom) 2021/100 of 25 January 2021*, the enterprise, in collaboration with the European Commission’s Joint Research Centre (JRC), organised its unique experience by specific areas of its core activity and presented them in the form of a Knowledge Product.
The Knowledge Product for 2024 has already been published on the JRC website.
The Automated Information System for Control of Technological Processes and Traceability of RAW is a web-based information system developed with the idea of tracking the RAW processing and management processes.
The goal of using the system is to regulate the procedure for registration, to ensure traceability and documenting of RAW with their inherent characteristics at each (in each activity) of their management stages. The system collects data related to the individual technological processes dealing with RAW. It ensures full traceability of RAW by type, activity, quantity, radionuclide and chemical composition, point of origin, storage destination and type of package used for conditioned waste. This allows on-demand queries by providing detailed and accurate information about any given RAW.
The system is capable of generating the so-called “Passport of conditioned RAW packages” containing basic information about the waste package accompanying the package to its storage destination. The developed automated information system also allows tracking the efficiency of the waste treatment installations and the effectiveness of the RAW processing methods used, which leads to improving safety in the decommissioning process, real-time RAW inventory and process traceability.
*In accordance with COUNCIL REGULATION (Euratom) 2021/100 of 25 January 2021, ANNEX I, the general objective of the Kozloduy programme is to assist Bulgaria in managing the safety challenges in respect of the decommissioning of Units 1 to 4 of the Kozloduy Nuclear Power Plant, complemented by the aim of enhancing the EU added value of that programme by contributing to the dissemination of knowledge on the decommissioning process (thereby generated) to all Member States.

A new Workshop for the production of reinforced concrete containers for RAW begins to function

infocenter — Thu, 01 Aug 2024 08:11:04 +0000

On 30 July, 2024, State Enterprise Radioactive Waste received a Utilization Permit for the building of the former Diesel Generator Station (DGS-1) located on the industrial site of Kozloduy NPP, for decommissioning purposes. By this document, the building, being reconstructed and equipped as a workshop for the production of reinforced concrete containers (RCC) for radioactive waste, is commissioned, and the actual work activities begin immediately – on 1st August.
The workshop is equipped with state-of-the-art rebar processing machines and three shuttering moulds, and the heating & ventilation systems allow year-round operation, which will lead to continuity in the RCC production process carried out by SERAW. “The commissioning of the Workshop will lead to a significant increase in the capacity of the Reinforced Concrete Containers Section,” stated its Head, Tsvetan Andreev, who also explained that this is of great importance in order to adequately meet the expected demands by the Wet Solid Waste Treatment Installation. According to the calculations, to ensure effective functioning thereof for 2024, 470 RCC should be produced.
The Construction Permit for the new workshop was issued in July 2020, and the construction site for the reconstruction of the building was opened in September 2020. Financing of the project is through 100% grant funds provided by the Kozloduy International Decommissioning Support Fund (KIDSF) supporting the decommissioning of Kozloduy NPP Units 1 to 4, administered by the European Bank for Reconstruction and Development.

Experts from the National Atomic Energy Agency (PAA) and the Radioactive Waste Management Plant (ZUOP) of Poland found the experience of State Enterprise Radioactive Waste impressive after the end of a scientific visit for technical cooperation, which took place in the period 23-30 July. The visit was initiated by the Polish country, which has yet to build nuclear power facilities, and was jointly organized by the Bulgarian Nuclear Regulatory Agency and the International Atomic Energy Agency.

The purpose of the scientific visit was for the Polish experts to familiarize themselves in due time with various aspects of decommissioning, radioactive waste management (RAW), as well as with the related regulatory activities.

The Polish delegation visited the Permanent Repository for RAW near Novi han to learn firsthand about the more important issues, linked with the monitoring programme, waste acceptance criteria and subsequent management thereof. In the following days of the visit, the focus shifted on the activities of the Specialized Divisions of SERAW at Kozloduy site. In a number of meetings, presentations and discussions at the Information Centre for Decommissioning, experts and part of the management of the Enterprise explained the main points in implementation of the Decommissioning Programme, RAW management, as well as further disposal. The Polish delegation had the opportunity to familiarize themselves visually with SERAW organisation and actual work processes by visiting in-situ the Turbine Hall of Units 1 to 4, Control Room – 2, Free Release Measurement Facility, Size Reduction & Decontamination Workshop, Storage Facility for temporary storage of conditioned RAW and the National Disposal Facility for low- and intermediate-level RAW on Radiana site. At the end of the visit, the Chairman of the Nuclear Regulatory Agency, Tsanko Bachiyski, and the President of the National Atomic Energy Agency of Poland, Andrzej Głowacki, joined the group of Polish experts. Both of them also participated in the final meeting of the scientific visit to SERAW Head Office, where they had a formal conversation with the Chairman of the Management Board of the Enterprise, Sergey Tsochev, on the outcome of the visit and the prospects of strengthening professional relationship.

“We would like to thank you for the hospitality and overall organisation, for the comprehensive informational presentations and for the opportunity to visit real operating facilities of SERAW. The experience of the Bulgarian experts in the field of RAW management is impressive. The SERAW experts gave us many good examples of safe and sustainable radioactive waste management. We are impressed with the successful implementation of the National Disposal Facility project. We look forward to future collaboration,” shared the representatives of the Polish RAW Disposal Enterprise upon ending their scientific visit.

Poland is one of the few countries in the former Socialist Bloc to remain without a nuclear power plant. Currently, the energy transition plans are ambitious, and over the recent years the country has been actively working to build nuclear power facilities.
