VUJE is a leader in the Slovak market, with a good name in Europe and a good reputation globally.

Specialised measurement systems for power engineering

We develop and deliver specialised measurement and monitoring systems according to individual customer needs. These systems conform to highly specific conditions. They are capable of being remotely configured or fully automated - sending the measured data to a defined server. Design packages are comprehensive; include software that enables the system configuration, data storage, and so on.

Radiation Monitoring Systems

We have developed the system ARAMIS - an integrated software tool meant for on-line monitoring and evaluating the radiation condition in the particular areas of nuclear power plant. The system also incorporates predictive algorithms for extrapolation of the course of event and effective procedure for operation during the accidents attended with radioactive leakage within the power plant units.

Hydrogen Concentration Measurement System

We have developed and manufactured the system for hydrogen concentration measurement during the accidents with loss of coolant in VVER units. Besides capability of the systems to operate in the conditions of severe accidents, they serve for simple service and calibration of the hydrogen sensors by using mobile equipment, with no need to dismount the measuring probes.

Training simulators

We have developed a multiple-function simulator of VVER 230 reactor, simulator technology and training system for practising the skills and procedures when operating the main control room in the units of nuclear power plants EBO, EMO, EDU, ETE. We have developed a simulator of distribution substations to train the power station controllers, simulator of the grid 110 kV and 22 kV for dispatchers training program. In cooperation with Slovenske elektrarne, a. s. we have developed the simulators of increasing the unit power level in the nuclear power plants EBO and EMO. We organise the courses for dispatchers operating on the Slovak Power System, i.e. SEPS, a. s. energy dispatching

Remote controlled manipulators

Manipulators dominate the fleet of equipment developed by our company, mainly applied to in-service inspections and maintenance of steam generators VVER-440 and VVER-1000.

Eddy-current probes

We run our own research and development of eddy-current probes for inspection of the following:

  • steam generator heat exchanging tubes,
  • tubes of the emergency water cooling system heat exchanger,
  • condenser tubes,
  • steam generator flange threaded holes,
  • steam generator studs,
  • reactor vessel studs,
  • main circulation pump studs,
  • reactor vessel cladding, reactor vessel nozzles,
  • steam generator collector inner surfaces .

Information systems

EPSIS® JISHM: We are developing a specific application program for a single information system of the Slovak economic mobilisation designated for the needs of economic mobilisation entities.

Equipment for radioactive waste (RAO) treatment

We develop and apply technology for processing, handling and storage of radioactive waste. Related to this, we evaluate functionality and safety of the surface and underground RAO storage by modelling the processes of radionuclides released and transported in the field of near and remote interactions and in biosphere. We develop and implement the program for monitoring the vicinity of National Radioactive Waste Repository in Mochovce.

Instrumentation and Control Systems

We modernize and develop Instrumentation and Control Systems for Nuclear Power Plants
