Pilot-Plant Testing of Magnetic Filters for the N-Reactor Primary Cooling Circuit

摘要

Data obtained during the laboratory loop test program using the high power HGMF indicates that removal efficiency for exp 60 Co and subsequently the bulk of the crud, will be greater than 90% at field strength above .1 Tesla for the expanded metal mesh matrix. However, since exp 54 Mn seems to exhibit paramagnetic behavior and the possibility of quantities of alpha iron forming during reactor shut down from oxygen inleakage, a field strength of .5 to 1 Tesla may be more appropriate for a full scale on-reactor installation. Crud loading of 50 gm per kg of matrix weight are readily obtainable and up to twice that amount has been reached. (ERA citation 08:005170)
