Future E.U. Needs in Materials Research Reactors

Objective

Most of European MTRs will be more than 40 years old by 2010.

This CA is addressing two relaxingly urgent problems:
1) The risk to have most of the MTRs closed down by the end of the decade.
2) To have shortly in Europe many obsolete research reactors from the safety viewpoint and therefore not to be able to respond to the industry, safety or research needs.

The objectives of this CA are to determine:
a) what will be the European irradiation needs in MTRs;
b) identify safety related issues encountered on research reactors and propose ways of strengthening safety.

Objectives will be achieved by gathering literature and contributions from experts and write a report giving qualitative and possibly quantitative assessment of irradiation needs and a guide of best practice for RR safety improvement.

Contribution to programme objective will be made in the following chapters:
Plant life management and extension (PLIM/PLEX),
integrity of equipments and structures,
Study of abnormal and accidental events,
Study of high burn-up UO(2) and MOX,
Study of transmutation (transmutation of actinides and LLFP),
Study of corrosion, erosion, hydriding, or deposition of corrosion products on out of core heat transfer surfaces in order to limit or decrease the irradiation dose and decrease the amount of wastes.
Medical and neutron beams need will be also considered.

In research reactors it will contribute to the following:
- Severe accident management;
- Operational safety of existing and future RR;
- Waste and spent fuel management and disposal.
