Available in abstract form only. Full text of publication follows: In the Netherlands there are some 200 producers of radioactive waste. Most of them generate only small volumes of low and medium level waste. These small volumes however cover a wide range of waste forms: solids, liquids of all nature, slurries, etc. Because of the resulting wide spectrum of radiological and chemical contaminations, a certain amount of flexibility is required in both solid and liquid waste treatment. In addition, the Nuclear Energy Act license requires a five yearly evaluation of the waste processing installation with respect to the Best Practicable Technologies. The bulk of the solid waste are compacted, conditioned as cemented packages and stored for at least hundred years. The low-level liquid waste is treated batch-wise as the volumes of liquid waste are too small to operate a continuous system. Moreover, batch-wise processing enables more flexibility. Discharge of treated water is bounded by concentration limits of chemicals and total activity per nuclide. Evaluation of the installation showed that the radiological constraints provide a larger degree of freedom to discharge, and the waste water treatment can effectively meet the required limits. The limits of concentration of chemicals are more restrictive. The liquid waste often has more chemical contamination than radiological. This paper describes the evaluation of the waste water treatment. (authors)
