A realistic field facility to simulate reactor spectra.
The design construction and characterisation of a simulated realistic neutron workplace field is described. Utilising a low-energy primary source of neutrons based on the 7Li(p,n) reaction, and a heavy water moderator, a broad spectrum is produced with energies extending from thermal to about 1 MeV. The field simulates the type of spectra encountered around UK gas-cooled reactors.
