Solutions and services for improved economics of the NPP

Nuclear safety analysis and licensing support

 VTT is the key provider of technical support to the Finnish nuclear authority. We provide services to our domestic nuclear industry and have more than two decades' experience in providing technical support and research services to foreign utilities, industries and regulatory bodies. An active member of the European Technical Safety Organisations Network (ETSON), VTT supports nuclear safety authorities in countries that are licensing and executing new nuclear builds.

​​​Apros - Dynamic Process Simulation

Apros is a simulation software product developed by VTT and Fortum for simulation of combustion and nuclear power plants.

​ ​​​

​​​Assessment and safety justification

VTT offers modelling and analysis methods and tools to the industry and regulators. Our independent assessment services cover a wide range from environmental testing and reliability analysis.

​ ​​​

​​​​FinPSA risk assessment tool

​FinPSA is a risk and reliability analysis tool intended for full scope PRA/PSA modeling. FinPSA is designed to support the main activities related to PRA/PSA

​ ​​​

​​​Model checking for automation

Model checking is an efficient method for supplementing e.g. safety analyses of instrumentation and control (I&C) systems in nuclear power plants

​ ​​​   ​ ​​​

​Human factors in systems engineering

​Successful design solutions need to be appropriate for their purposes and fit for human use. We provide services that place human experience and mindful human control in the centre of system design.

Optimising nuclear plant life management & material performance

VTT helps nuclear power plant owners, operators and suppliers to maintain ideal conditions and to maintain component life at optimal levels. We offer a unique, independent and internationally recognized combination of deep industry knowledge, research & development facilities, and practical experience. Customers rely on us for our material and component characterisation abilities and to safely and accurately evaluate their in-service condition and lifetime. Read more about optimising nuclear plant life management and material performance

Advanced nuclear technologies

VTT is committed to the development of next generation nuclear technologies through advanced computer modelling and software. Nuclear authorities use our models for next generation reactor safety modeling and the characterisation of steel-based materials. Read more about advanced nuclear technologies

Nuclear waste management and disposal

How do you permanently dispose of nuclear wastes so that it does not harm future generations? VTT has been refining the answer to this very question for over 30 years. In that time we have played an active role in developing practical Finnish and Swedish waste management solutions for high level nuclear waste (Posiva and SKB), for other waste forms (TVO and Fortum), as well as solutions for regulatory authorities (TEM, STUK and SSM).

Decommissioning of FiR 1 nuclear reactor

The FiR 1 research reactor, which has served as a key nuclear energy and educational research facility for 50 years, was shut down permanently on 30 June 2015. VTT is applying for a decommissioning licence from the Council of State in 2016. Read more about decommissioning the FiR 1 nuclear reactor
