The JET experimental programme has been extended from its former formal closing date, end of 1992, to the end of 1996. The extension allows the study of plasma operation with a pumped divertor to be installed in the JET vacuum vessel during a shutdown in 1992–1993[1]. As a consequence the final phase of JET, which involves the use of tritium to study D-T plasmas, will be delayed to 1996. In view of this delay it was decided to adopt a stepwise approach to the introduction of tritium in JET and to carry out a tritium experiment within limits imposed by restrictions on vessel activation and tritium usage. The objectives were:
