ABSOLUTE REACTIVITY MEASUREMENT FROM TRANSIENT BEHAVIOUR OF A SUBCRITICAL NUCLEAR REACTOR
Technical Report
·
OSTI ID:4331218
It is shown that absolute reactivities can be measured with good accuracy from the transient behavior of a subcritical nuclear reactor. The method is characterized by the application of step functions (either in neutron source strength or in reactivity) and by the observation of a time lag of the integrated reactor power. Simple formulae for the least square fit of experimental data are deduced, and some experimental checks at the Swiss swimming pool reactor SAPHlR are briefly summarized. (auth)
