During a hypothetical severe accident in a pressurized water reactor (PWR), fission products (FPs) are released from the nuclear fuel and may reach the reactor containment building. Among the FPs, ruthenium is of particular interest due to its ability to form volatile oxide compounds in highly oxidizing conditions. In addition, ruthenium is a very hazardous compound because it is chemically toxic and also because of its radiotoxicity. The topic of ruthenium is examined in terms of nuclear… 
Recent advances in understanding ruthenium behaviour under air-ingress conditions during a PWR severe accident
Abstract In a hypothetical severe accident in a Pressurised Water Reactor (PWR), Fission Products (FPs) can be released from the overheated nuclear fuel and partially transported by gases, composed
Interaction of ruthenium tetroxide with surfaces of nuclear reactor containment building
Abstract During a severe nuclear accident, different fission products will be released from the nuclear fuel and some of them may eventually reach the containment building. Ruthenium is considered to
FOR THE DEGREE OF DOCTOR OF PHILOSOPHY TRANSPORT AND CONTAINMENT CHEMISTRY OF RUTHENIUM UNDER SEVERE ACCIDENT CONDITIONS IN A NUCLEAR POWER PLANT
During a severe nuclear accident volatile elements and elements readily forming volatile compounds are the main concern regarding the release of radioactive material to the environment. As ruthenium
Impact of Ag and NOx compounds on the transport of ruthenium in the primary circuit of nuclear power plant in a severe accident
Ruthenium is a semi-volatile element originating as a fission product in nuclear reactors that can be released in case of a severe nuclear accident. In this work, the impact of atmosphere composition
Interactions of RuO4(g) with different surfaces in nuclear reactor containments
During a severe nuclear reactor accident with air ingress, ruthenium in the form of RuO4 can be released from the nuclear fuel. Hence, it is important to investigate how the reactor containment is

Deposition of RuO4 on various surfaces in a nuclear reactor containment
During a severe nuclear reactor accident with air ingress, ruthenium can be released from the nuclear fuel in the form of ruthenium tetroxide. Hence, it is important to investigate how the reactor
Ruthenium release from fuel in accident conditions
Abstract During a hypothetical nuclear power plant accident, fission products may be released from the fuel matrix and then reach the containment building and the environment. Ruthenium is a very
Influence of fission products on ruthenium oxidation and transport in air ingress nuclear accidents
Abstract In separate effect tests at 1000–1200 °C Ru oxidation rate and content of Ru in escaping air flow have been studied with special emphasis on effects of other fission product elements on the
Interaction of ruthenium tetroxide with iodine-covered surfaces of materials in nuclear reactor containment building
ABSTRACT Volatile iodine and ruthenium species are likely to be released from the fuel during a severe nuclear accident. Both iodine and ruthenium are expected to deposit on the surfaces in the

Fission-product release during accidents — an accident management perspective
One of the aims when managing a reactor accident is to minimize the release of radioactive fission products. Release is dependent not only on the temperature, but also on the partial pressure of
