In the scope of the second startup phase of the FRJ-1 (MERLIN), the thermal and epithermal flux distributions in the experimental installation of the reactor were measured with the help of an activation probe. At the boundary of the core the fast flux was determined with phosphate glass and sulfur films, and the properties of the films wereinvestigated. It is shown that for use of phosphate glass films, the long-lived portion of the thermal activation must be considered. The sulfur films showed no interfering activity. The fast neutron flux at the boundary of the core was on the order of 10/sup 7/ n cm/sup -2/ sec/ sup -1/ watt/sup -1/. (tr-auth)
