Assessment and Upgrading of the Novi Han Monitoring System (Bulgaria)

The tasks of this project can be summarised as follow. The site assessment has produced the following outputs: the Novi Han team has practiced the sampling of soils, sediments and vegetation, the on-site and laboratory analysis have not shown any significant release from the vaults with the exception for 3H that has been detected in significant concentration in water samples collected from boreholes. The critical analysis of the current monitoring program and the laboratory equipment have revealed some weak points. Remedial measures have been proposed where and when required. An evolutional monitoring program has been defined in accordance with the EC recommendations and the budget required to its implementation has been estimated. A 2 weeks training has been organized in Belgium for 2 peoples from Novi Han repository; the training was focused on methods required by the monitoring program. Four QA analytical procedures have been written by the trainees and have been verified by the IRE. The skeleton of a radiological database has been drafted; its realization is far beyond the scope of the current project and is strongly linked to the QA system anyway. The priority equipments needed for the implementation of the monitoring program have been defined in agreement with the Novi Han staff. Priority equipment have been purchased in the limits of budget.
