This report gives the text of three papers presented at a 1988 meeting on fusion technology. The first discusses JET progress towards D-T operation; experimental results obtained in 1988 are reviewed. In particular, upgrading JET has allowed operation at plasma currents up to 7MA with material limiter and 5MA in the X-point mode. Future enhancements are considered and recent developments in the area of remote handling are briefly described. Details of the plant used to process tritiated exhaust gases are given and progress in safety analysis and waste handling are reported. The second paper discusses the forces acting on the JET vacuum vessel during disruptions and the consequential operational limits. Particularly undesirable are vertical disruptions due to possible failure of the vertical stabilisation system. Two support rings are planned at the inner periphery of the vessel to supplement the outer ones and to prevent unacceptable radial deflections. The final paper discusses the technical details involved in upgrading the JET magnet system for 7MA plasma and the effects on the poloidal and toroidal magnet systems, including magnetic forces and mechanical and thermal stresses in the coils.
