Past experience can usefully inform current practice and ensure the avoidance of known problems. Learning from such experience can also assist in maintaining an industry’s reputation and the good will of stakeholders. This publication collects Member State experiences in the design, construction and operation of spent fuel storage facilities. It collates the improvements which have been incorporated into the design of new storage facilities over the past fifty years, highlights good operating practices and designs and shares lessons learned. The information provided will assist those Member States that already have a developed storage capability and also those considering development of a spent nuclear fuel storage capability in making informed decisions when managing their spent nuclear fuel.
