•Neutronics experiments are in preparation at JET for DTE-2 campaign.•Shutdown dose rate benchmark experiments will be performed to validate ITER relevant tools.•Advanced D1S, MCR2S, R2Smesh and R2SUNED are the European tools under validation.•Satisfying results were obtained in the last DD benchmark experiment but efforts to reduce the uncertainties were needed.•The current computational and experimental efforts seem promising to improve the benchmark accuracy. In the frame of the WPJET3-DT Technology project within the EUROfusion Consortium program, neutronics experiments are in preparation for the future deuterium–tritium campaign on JET (DTE2). The experiments will be conducted with the purpose to validate the neutronics codes and tools used in ITER, thus reducing the related uncertainties and the associated risks in the machine operation. This paper summarizes the status of previous shutdown dose rate benchmarks experiments and analyses performed at JET and focuses on the computational and experimental efforts conducted in preparation of the future DTE2 experiments. In particular, preliminary calculations and studies to select detectors and positions aimed to reduce uncertainties in the shutdown dose rate experiment are presented and discussed.
