Subcritical Tests on FRJ-1 (Merlin-Julich); UNTERKRITISCHE VERSUCHE FUR DEN FRJ-1 (MERLIN-JULICH)

Technical Report ·
OSTI ID:4814433

Subcritical tests were carried out for the FRJ-1 (Merlin-Julich) in England. The critical mass was determined for the followirg nuclear arrangement: compact core; square, elongated, and U-shaped core; as well as a core with central air and water voids. For one series of core configurations, the efficiency of the coarse and fine control elements was determined. Further measurements referred to the determination of the temperature coefficients of the core and reflector, as well as to the distribution of the statistical weight and the void coefficients of reactivity in the compact core. The resuits of the measurements are given in tabular form. (tr-auth)
