ACOUSTIC FREQUENCIES OF COOLANT IN PRIMARY CIRCUIT OF NPP TEMELIN AND POSSIBILITY OF RESONANCES WITH FUEL ASSEMBLY TVSA-T
Pečínka L., Švrček M.
pages 507 - 510, full text

On the basis of electromechanical analogy is as criterion of possible interaction of acoustic waves in primary circuit of NPP Temelin derived so-called quality factor Q. The Q value determines a range of coolant acoustic frequencies in which there is a natural frequency of fuel assembly and in which resonance is realized. The range of fuel assembly frequency is named as pass band. Estimated values of Q and pass band are given. The developed methods algorithms of calculation and quantitative estimations of coolant pulsation frequencies, Q factor and pass band allow developing coolant parameter control actions necessary for prevention of resonances.
