INTRODUCTION

The High Flux Reactor (HFR) Petten belongs to the Institute for Advanced 
Materials of the Joint Research Centre of the European Communities.

The HFR is a high power (45 MW) multi-purpose research reactor. It provides of 
high flux in-core positions for irradiation testing of reactor materials, as well as 
for high grade radioisotope production. A large, versatile, pool-side facility outside 
the reactor vessel is extensively used for transient testing of reactor fuel, as well as 
for processing of materials with neutrons. In addition, 12 horizontal beam tubes are 
available for serving a neutron scattering laboratory and a number of other purposes.

The present programme largely profits from this variety of irradiation possibilities. 
It covers the fields of nuclear fission energy with fuel and structural materials 
investigations, thermo-nuclear fusion with damage studies on all kinds of structural 
materials as well as performance testing of blanket breeder materials, fundamental 
research with neutrons mainly in solid state physics and materials science, large 
scale radioisotope production for medical and industrial applications, neutron 
activation analysis, neutron radiography and research towards cancer therapy 
with neutrons (boron neutron capture therapy).

Full attention is given to quality assurance towards safe and efficient operation of 
the reactor which in itself is an explicit programme objective.

In 1992, the operation record of the HFR was excellent again. In total, 280 operation 
days were achieved corresponding to an overall availability of slightly higher than 
75%. The utilization of the HFR decreased slightly from 69% in 1991 to 63% in 
1992. Despite a significant increase in radioisotope handling, the occupational dose 
could be kept at a remarkably low level. A large number of regular and preventive 
maintenance activities were executed at schedule without loss of operation time.

The utilization of the HFR undergoes a significant transition. Whereas the 
traditional materials testing programmes for fission reactors, in particular the 
HTR and FBR related projects, as well as fusion materials irradiations were 
decreasing, radioisotope production, mainly for the medical sector, increased 
considerably. Research towards boron neutron capture therapy contributed an 
important share again. Also neutron radiography and activation analysis as 
traditional services at the HFR maintained a stable position.
