Nuclear safety
Special Expert Group on Fuel Safety Margins
A topical meeting
on LOCA Fuel Safety Criteria was held in Aix-en-Provence on 22-23 March. Research
and industry organisations from France, Hungary, Japan, the Russian Federation
and the USA presented 14 papers in all. The papers covered three main issues:
post-quench ductility; the impact of axial constraint; and fuel relocation.
Proceedings of the meeting, along with conclusions and recommendations, will
be published shortly.

CSNI workshop on seismic re-evaluation of nuclear facilities
A workshop to discuss seismic re-evaluation of nuclear facilities was held at the European Commission Joint Research Centre's Ispra site on 26-27 March. Seismic re-evaluations have been made in many countries, covering many types of facility. However, not all have fully implented the process. Some NEA Member countries reported partial completion as part of an ongoing process, or re-evaluation being tied to a periodic safety review or other licensing arrangements. Over 50 participants took part in the workshop, representing a broad mix of academic and nuclear industry officials. Their experiences provided a good spread of national and international perspectives. A total of 26 papers were presented, which will be published by the end of 2001.
