Major Enhancement Projects

ITER-like First Wall Experiment Project

The ITER-like Wall Project will replace JET's existing carbon wall with beryllium and tungsten material configuration which is directly relevant to ITER. The Framework 7 phase of operation will aim to acquire the operational experience and the scientific basis for operating ITER in a way that is compatible with the material characteristics and performance objectives for ITER.

Neutral Beam Enhancement Project

The fundamental aim of the NBE project is to provide the increase in JET additional heating power and pulse length required to fulfil the programme objectives of JET in the proposed Framework Programme 7 phase of operation dedicated to the preparation of ITER. The changes to the NB system are also aimed at improving its overall reliability and availability.

High Frequency Pellet Injector Project

The aim of the HFPI project is to provide JET with a new 50-60 Hz deuterium ice pellet injector for ELM mitigation and deep fuelling experiments in preparation of ITER.

Plasma Control Upgrade Project

At present the study of scenarios with large ELMs is limited by high force disruptions which occur when the response to the ELM produces a radial field current excursion larger than the Fast Radial Field Amplifier (FRFA) current limit. The first objective of the project is to double the survivable ELM size in JET operation. The second objective is to validate vertical stabilisation systems for ITER. The implied enhanced control logics will be implemented with an Enhanced Radial Field Amplifier (ERFA).
