Nordic and a Swedish Network for Generation IV Nuclear Power Reactors
A prestigious OECD project run by Studsvik Nuclear since 2004 will continue for another five years. This is the international fuel test program SCIP (Studsvik Cladding Integrity Project) with participants from Europe, Japan, the US and Korea.
Studsvik will continue in the role of operating agent for SCIP II.
The main studies conducted as part of the SCIP project concern hydrogen-related failure mechanisms for fuel cladding. In the project different cladding materials are tested, mainly by means of mechanical testing and reactor tests. Modeling has also been carried out to simulate how the fuel and cladding is affected during reactor operation. SCIP focuses on increasing the possibility of predicting mechanisms that can cause damage to cladding. It is conducted in the form of experiments, studies of fundamental mechanisms, development of suitable testing methods and knowledge transfer. The results are used to support the nuclear power industry in assessing margins for avoiding crack formation in the cladding that surrounds the fuel pellet. This leads in turn to increased nuclear fuel safety.
