Profiling of energy deposition fields in a modular HTHR with annular core: Computational/experimental studies at the ASTRA critical facility

The paper presents the results obtained from the computational/experimental studies of the spatial distribution of the 235 U fission reaction rate in a critical assembly with an annular core and poison profiling elements inserted into the inner graphite reflector. The computational analysis was carr...

Beschreibung
Zusammenfassung:	The paper presents the results obtained from the computational/experimental studies of the spatial distribution of the 235 U fission reaction rate in a critical assembly with an annular core and poison profiling elements inserted into the inner graphite reflector. The computational analysis was carried out with the codes intended for design computation of an HTHR-type reactor.
