About LEI

In 1948 the Lithuanian Academy of Sciences established the Institute of Technical Sciences. Since 1992 institute was renamed to Lithuanian Energy Institute

Directions of Scientific Research Activities

In the last years scientific activities in the Institute were carried out according to five main research directions approved and financed by the Government of Lithuania:

I. Development of energy economy planning methods, investigation of safety and reliability of the power plants, their impact on the environment, efficient energy consumption and the renewable energy sources.

1. Creation of conceptual and methodology basis for the formation of state policy in the energy sector and its application for development of the energy sector.

2. Investigation of the regional ecosystems sustainable development, related to nuclear power and expansion of the Klaip?da port.

II. Investigations in the fields of thermal physics, fluid mechanics and metrology.

1. Experimental and numerical investigations of heat and pulse transfer processes in one-phase and two-phase flows.

2. Investigation of the weighting method with the aim to achieve international level of the state primary standard of the air (gas) and flow unit and volume and flow characteristics of the standards of the water and oil products in final stage of establishing.

III. Simulation of complex systems, development of their control methods and technologies.

1. Monitoring of the power and heat systems, creation of the control models and their investigation.

IV. Investigation of energy systems’ construction elements aging and development of new multifunctioned materials.

1. Investigation of influence of corrosion on the structure of austenitic and perlitic steels and of zirconium alloy structure changes as a consequence of thermal blow.

2. Manufacture of the electrolyte yttrium stabilized zirconium coatings of electrochemical solid body fuel element using plasma spraying method.

V. Investigations of combustion and plasma processes in the fields of fuel saving, reduction of environmental pollution and thermal decontamination of materials.

1. Experimental investigations of fuel and waste particle gasification and combustion.

2. Synthesis and property investigations of the catalytic coatings formed using plasma technologies and intended for decontamination of combustion products.
