One of the experimental machines of the Tokamak series, a European machine coming into use in 1992 will operate with a plasma fed with Deuterium/Tritium mixtures resulting in a greatly increased neutron flux. This will activate the machine's components to such an extent as to permanently prohibit staff access to the hall for any maintenance tasks. The paper describes several of the tasks which intervention teams will have to carry out and infers from them the philosophy and the equipment which will have to be applied in order to guarantee from a distance the availability of JET. It briefly reviews experience gained in the course of the programme from tests on models. These were initiated nine months ago to establish whether those tasks that are essential for the running or safety of the machine can be carried out from a distance. A list of unsolved problems which make life complicated for the operators is suggested to the industry and to research centres. The solutions to these problems will find an application not only on the following Tokamak but in the majority of hostile environments.
