Abstract: Some results are presented of strain measurements carried out using a novel, modified version of the energy- dispersive neutron transmission diffraction method which has been implemented on a conventional diffractometer at a steady-state reactor. This method, which has so far been used only on time-of-flight instruments, can also be easily and successfully used at steady-state sources. The EDNTD method presented is based on the precise measurement of the Bragg diffraction edge by using focusing crystals and is complementary to the method of strain measurements by Bragg diffraction angle analysis. It allows changes $Delta@d/d of lattice spacings with sensitivity down to some 10$+$MIN@5$/ to be investigated for reasonable, irradiated sample volumes and counting times, even at a medium-power research reactor. !5
