International Projects

Innovation in concrete design for hazardous waste management applications (ICONDE)
The project aims to create new concretes and study their properties, partly using shale ash as cementing material. Among all the Baltic States, Latvia produces the most cement. The admixture of oil shale ash (energy sector waste in Estonia) with standard cement allows the production of specialized cement with low consumption of natural and energy resources, reducing the pollution caused by the industry and the cost of cement / concrete, as well as CO2 emissions. In addition, specific properties of such concrete are predicted – the required strength is easily achieved and poor filtration of heavy metal impurities through the concrete mass. The above describes the development of specialized concrete for a very important application – long-term storage of hazardous waste by immobilizing them in concrete containers or directly in the concrete mass. It is also possible to build protective structures in the radioactivity industry. There are several sources of hazardous waste in the Baltic and Nordic countries, from highly radioactive waste directly related to the use of nuclear energy and specific components of medical equipment to toxic substances or metals with insignificant radioactivity that can occur in various sectors such as metal extraction and recycling. An example of a source of large-scale radioactive waste of all stages is the decommissioning of the Ignalina Nuclear Power Plant (NPP). At the time of writing, most of the Ignalina NPP radioactive waste is still in temporary storage sites and a long-term solution is still being sought. The long-term lack of hazardous waste storage solutions and technologies is a problem for the entire Baltic region.

Working together for a green, competitive and inclusive Europe

Publicity

February - April 2022

In the fourth quarter of the project, the development of numerical models for the study of the mechanical properties of concrete was started. Numerical modeling will allow to evaluate the effect of the amount of oil shale ash and added fibers on the development of cracks in concrete without performing laboratory experiments. In parallel, work has begun on numerical modeling of shielding properties. The production of concrete samples without fibers using different amounts of oil shale ash has been completed in the RTU laboratory.
The project partners have prepared and submitted a joint report to the international scientific conference NORM X 2022, which will take place from 9 to 13 May in the Netherlands. RTU professor Andrejs Krasņikovs will participate in the first international online conference «Nuclear Energy for Latvia» with a report «ICONDE - new concrete for nuclear waste and radioactive waste management». The conference will take place on May 18, 2022.
The achieved goals of ICONDE in the first year are the result of intensive cooperation between the project partners – Riga Technical University, Arctic University of Norway, Lithuanian Energy Institute and University of Tartu.

ICONDE kick-off meeting in Narvik

The kick-off meeting of ICONDE project was held at UiT campus Narvik instead of RTU due to COVID 19 restrictions in Baltic countries. All project partners attended, namely:

  • Sabine Upnere and Andrejs Krasnikovs    (RTU, Riga Technical University), 
  • Volodymyr Gulik, Riho Motlep and Siiri Salupere    (UT, University of Tartu), 
  • Iveta Novakova, Ashfaque Ahmed Jhatial and Eirik Gjerlow (UiT, Arctic University of Norway), 
  • Mindaugas Vaišnoras, Inna Pitak and Algirdas Kaliatka (LEI, Lithuanian Energy Institute)

 The meeting lasted for two days and besides discussion about completed tasks, evaluation of the further plan and project progress was addressed in detail. Many emphases were given to live events that have to be rescheduled (due to COVID 19 pandemic situation). All partners recognized the increased need for good dissemination of results towards industry and other research institutes. The ICONDE project conducts research about concrete design for hazardous waste management applications. This includes the management of radioactive waste, which is connected mainly to the decommissioning of the Ignalina nuclear power plant, particularly gamma radiation and neutron shielding. Furthermore, the ICONDE project fully complies with nowadays needs:
•    EU strategy connected to hazardous (including radioactive and nuclear) waste management. 
•    The present geopolitical situation has strongly brought up the need to establish energy independence in Europe – the use of nuclear power in European countries is likely to increase in the future. The ICONDE project is devoted to the development of innovative and efficient materials for safe radioactive waste management, which guarantees modern radiation protection requirements.
•    UN´s sustainable development goals as circular material flow are addressed by adding oil shale ash, waste from energy production in Estonia, into the concrete where it is replacing partly cement. 
The first day of the event was closed by dinner, where partners from Baltic countries tasted «Boknafisk», a traditional dish from Northern Norway. The second day of the kick-off meeting started with a city tour and visit to the LKAB shipping facility guided by Jorn Eldby. Twelve participants from all four project partner institutes were satisfied with the event and agreed that this physical meeting would positively impact project progress. 
The next meeting of the project participants is scheduled for June 2022 in Tartu.

 

November 2021 - January 2022
In the third quarters of the ICONDE project, research into fiber and non-fiber ash concrete for the storage of hazardous waste was continued. The selection of fibers to be used in further research, the definition of their parameters, the basic problems of radioactive waste storage in relation to the mechanical properties of the cementing material have been performed. In order to be able to determine the effect of oil shale and various fibers on the properties of concrete, basic samples have been prepared for comparison using traditional concrete production recipes, as well as the first tests of mechanical properties have been performed. The aims and tasks of numerical experiments in fiber concrete have been formulated in the discussions.

 

August - October 2021
In the second quarter of the project, the study of the chemical and mineralogical properties of oil shale ash was completed, which is an essential precondition for further activities related to the modeling of composite materials, gamma and neutron shielding experiments. Information on existing sources of hazardous waste in the project partner countries has been collected. Such information makes it possible to identify more specifically the potential applications of the new type of concrete in the partner countries.

At the 62nd RTU International Scientific Conference, the wider scientific community was informed about the activities of the ICONDE project. The scientific section «Engineering, Mechanics and Mechanical Engineering» organized by the Faculty of Mechanical Engineering, Transport and Aeronautics took place on October 14 in a hybrid form both on-site and remotely. Normunds Jēkabsons, the leading researcher of the project, participated in it with the report «ICONDE project, its description and achievements».

 

May - July 2021
Scientists in the Department of Theoretical Mechanics and Strength of Materials at the Institute of Mechanics and Mechanical Engineering, Faculty of Mechanical Engineering, Transport and Aeronautics have started research into a new type of concrete for hazardous waste storage using oil shale ash as a raw material.

The use of basalt and newly developed basalt-boron fibers instead of traditional steel reinforcement is one of the research directions. Such specialized concrete with low gas and liquid permeability as well as radiation shielding properties due to boron additives can be used for cementation of hazardous waste - both for transportation and long-term storage (for example, in some containers or directly in bulk). The implementation of the project started on May 1, 2021.

In the first quarter of the project, researchers carried out chemical and mineralogical research of oil shale ash and determination of critical parameters and requirements for materials used in radioactive waste management.
