The deuterium inventory at Joint European Torus (JET) after the 2007–2009 experimental campaign has been evaluated using Nuclear Reaction Analysis (NRA) and Secondary Ion Mass Spectrometry (SIMS). A full poloidal set of divertor tiles were analysed providing estimation for the total deuterium retention of about 48g. Deuterium is trapped mainly at the inner divertor floor tile and outer divertor floor tile. The total deuterium retention is ∼2%.
