RSG-GAS reactor, Operation safety, Target irradiation, Radioisotope production, UtilizationAbstract
The RSG-GAS multipurpose reactor is operated to serve the utilization in the field of radioisotope production, neutron activation analysis (NAA), and material research. The reactor actually has the power of 30 MW thermal, but upon considerations of efficiency and of most user’s requirements, the reactor is mostly operated at the power of 15 MW thermal, 5 days a week to produce a primary radioisotope from the target of 2 grams U-235. To ensure safe operation and optimum utilization, a safety procedure was established. The paper is intended to assess the operation safety in serving radioisotope target irradiation at its cycle operation. The assessment was carried out for core numbers 102 – 105. The result shows that excess reactivity and shutdown margin reactivity are safe to provide the target irradiation in the core for each cycle operation.
