Critical data for homogeneous U(NAT)O2-PuO2-H2O-systems with PuO2-fractions of 35 and 45 Wt% of the total oxide
Description
Critical data for homogenous U(NAT)O2-PuO2-H2O-systems with PuO2 parts of 35 and 45 wt.% PuO2 of the total oxide were drawn up, whereby the plutonium was present as 100 wt.% 239Pu. In the case of the 45 wt.% PuO2 fraction Pu was also present as a mixture of 95 wt.% 239Pu and 5 wt.% 240Pu. All systems had a water reflector of 30 cm thickness (total reflection). Calculations were carried out using the spectral programme GAMTEC (16 energy groups, P1 approximation) and with the transport code PTF-IV in S8 order. Experiments were verified by calculations to support the cross-sections used. The discrepancy between the experimental and calculated values was +-1%. (orig.)

Es wurden Kritikalitaetsdaten fuer homogene U(NAT)O2-PuO2-H2O-Systeme mit PuO2-Anteilen von 35 und 45 Gew% PuO2 am Gesamtoxid erstellt, wobei das Plutonium als 100 Gew% 239Pu und fuer den Fall von 45 Gew% PuO2 zusaetzlich als Gemisch aus 95 Gew% 239Pu und 5 Gew% 240Pu vorlag. Alle Systeme hatten einen 30 cm starken Wasserreflektor (volle Reflexion). Die Berechnungen erfolgten mit dem Spektralprogramm GAMTEC (16 Energiegruppen, P1-Approximation) und mit dem Transportcode DTF-IV in S8-Ordnung. Zur Abstuetzung der verwendeten Wirkungsquerschnitte wurden Experimente nachgerechnet. Die Abweichungen zwischen den Experimenten und entsprechenden Nachrechnungen betragen +-1%.
