TASK 5 - Safety & Radioprotection

eurisol ds
A reliable procedure will be provided for a) characterisation of radioactive inventory, b) dose and shielding estimates, c) containment of radioactivity, d) radioactive target handling, storage and disposal, e) safety and risk analysis, and f) conformity to the legislation. Major efforts will be directed to the high power target station (few MW).

This report summarises the radiation protection studies conducted for the EURISOL post-accelerator. The goals of the work were to study the important radiological aspects of the post- accelerator layout, to make pre-conceptual designs for the most important items including the tunnel, the beam dump and experimental area, to characterize the radiation environment through over the installation and its impact on the EURISOL facility, and to identify further required analyses.

Estimation of Radiation Protection Shielding for a EURISOL Linear Proton Accelerator
24/06/2009 -Task : TASK 5
Author(s) :Thomas Otto, CERN

A linear accelerator for protons, based on superconducting radiofrequency technology, is envisaged as a driver accelerator for the isotope production targets in a future EURISOL facility. This note reports basic estimates of the required radiation protection shielding of such an accelerator.
Radiation protection aspects of the EURISOL Multi-MW target shielding

Author(s) :D. Ene, J.-C. David, D. Doré, B. Rapp, D. Ridikas

This work is focused on the approach used to assess the radiological characterisation and to support waste analysis for the multi-MW power target shielding being the most challenging both in terms of technological and safety issues.
Screening Approach to the Activation of Soil and Contamination of Groundwater at Linear Proton Accelerator Sites
06/02/2009 -Task : TASK 5
Author(s) :Thomas OTTO, CERN

The activation of soil and the contamination of groundwater at proton accelerator sites with the radionuclides 3H and 22Na are estimated with a Monte-Carlo calculation and a conservative soil- and ground water model. The obtained radionuclide concentrations show that the underground environment of future accelerators must be adequately protected against a migration of activation products. This study is of particular importance for the proton driver accelerator in the planned EURISOL facility.
