JOINT RESEARCH ACTIVITY 4:
"IRRADIATION IN PRESENCE OF LBE"
Responsable person: Friedrich Groeschel, PSI - friedrich.groeschel@psi.ch
The aim of this JRA is to cover a major lack in the capabilities of the existing facilities to perform experiments
combining HLM and radioactivity. Hence the development of a high temperature lead alloy loop is planned to be installed in a MTR reactor BR2 under the leadership of SCK•CEN.
The in-pile HLM loop should be designed in such a way that it can be used for the following purposes that are common to the development of GEN-IV LFR and Pb(-Bi) ADS whereby some of these points are as well covered in LiSoR.
- LFR materials compatibility with Pb(-Bi) under irradiation:
- cladding, reactor internals, heat exchangers, pumps;
- corrosion.
- Pb-Bi conditioning and purification technologies in radio-active conditions.
- Radiation effects on coolant chemistry control:
- oxygen sensors and oxygen control;
- 210Po control;
- corrosion products control.
- Reactor components in Pb(-Bi) under irradiation:
- ultrasonic sensors for in-service inspection;
- liquid metal pumps;
- instrumentation.
