Abstract:

The response of reactor instrumentation to in-core void formations that simulate nucleate and partial-film boiling was studied in the Reactivity Test Assembly. The voids were generated by bubbling air through the desired element position. The experiments were performed with core configurations representing the Ground Test Reactor and the Aerospace Systems Test Reactor. The void coefficient of reactivity and the instrumentation response were measured for void fractions of up to 0.15 delta VV. Simulated boiling was not detected by observation of the normal reactor instrumentation, but amplification and bandpass filtering permitted detection for singleelement void volumes greater than 0.05 delta VV.
