- Abstract
- The Finnish national research program on Reactor Safety concentrates on the search of safe limits of nuclear fuel and the reactor core, accident management methods and risk management of the operation of nuclear power plants. The annual volume of the program has been about 26 person years and the annual funding FIM 15 million. This report summarises the structure and objectives of the program, research fields included and the main results obtained during the period 1995-May 1997. In the field of operational margins of a nuclear reactor, the behavior of high burnup nuclear fuel is studied both in normal operation and during power transients. Research on accident management aims at development and validation of calculation methods needed to plan preventive measures and to train the personnel to severe accident mitigation. In the field of risk management probabilistic methods are developed for safety related decision making and for complex phenomena and event sequences.
