[en] The objectives of activities related to policy support on radiation protection is: (1) to support and advise the Belgian authorities on specific problems concerning existing and potential hazards from exposure to ionizing radiation in normal and accidental situations,;(2) to improve and support nuclear emergency-response decisions in industrial areas from an economical point of view. The main achievements for 1997 are described

[en] Exclusive and inclusive (ν_μ,μ^-), (ν_e,e^-) cross-section and μ^- -capture rates are calculated for ¹²C and ¹⁶O using the consistent random phase approximation (RPA) and pairing model. After introducing a pairing correction to the RPA results the flux-averaged theoretical (ν_μ,μ^-), (ν_e,e^-) cross-section and μ^- - capture rates in ¹²C are in good agreement with experiment. Predictions of (ν_μ,μ^-) and (ν_e,e^-) cross-section in ¹⁶O are also presented. (authors)

[en] In 1990 the operation of the High Flux Reactor was carried out as planned. The availability was 96% of scheduled operating time. The average utilization of the reactor was 71% of the practical limit. The reactor was utilized for research programmes in support of nuclear fission reactors and thermonuclear fusion, for fundamental research with neutrons, for radioisotope production, and for various smaller activities. General activities in support of running irradiation programmes progressed in the normal way. Development activities addressed upgrading of irradiation devices, neutron radiography and neutron capture therapy
