Site release in the decommissioning of nuclear installations

摘要

Spanish regulatory framework for the decommissioning process of a nuclear facility ends up with adecommission statement, which releases the licence-holder of the facility from its responsibilities as an operator. Italso establishes –where a restricted site release applies– the appropriate future use restrictions, and the responsibleof both maintaining such restrictions and ensuring their compliance. Releasing a site implies eliminating allradiological monitoring. The Regulations, however, did not specify either the radiological conditions to be met forthe site to be released, or the possibility of a partial release –with or without restrictions–. In case of restricted siterelease, the Regulations did not specify either the required criteria for such a release. This paper presents the mainfeatures of the Safety Instruction IS-13 “Radiological criteria for the release of Nuclear Facilities Sites” issuedrecently by the Spanish Nuclear Safety Council as a new specific regulation. This Safety Instruction establishesthe requirements and conditions for the release of nuclear facility sites, that is, radiological criteria on the effectivedose to the public, partial release of nuclear facility sites and restricted release of nuclear facility sites.
