What happens to the diffusive properties and the porosity when cement and clay come in contact? At PSI, scientists are studying cement and clay as sealing materials in underground repositories for radioactive waste.

Calculational evolution helps in bringing together different aspects of nuclear physics, namely “nuclear reaction theory” and “reactor physics”.

Combining IC’s capabilities for speciation analysis and the new ICP-OES for swift and reliable wastewater analysis, the PSI hotlab now offers a comprehensive set-up for routine wastewater examinations providing future autonomy from external contractors for wastewater management.

The recent stress corrosion cracking (SCC) in Alloy 182 in reactor pressure vessel nozzles, reactor internal attachment or penetrations dissimilar metal welds in boiling water reactors (BWRs) represent a serious potential safety concern.
