1:1:1 ratio can be used as well. Fig. 3.4.8 shows the cleaning of the expansion vessel of
NACIE-UP loop from residual Pb/Bi with CH 3 COOH+H 2 O 2 mixture after a thermal-
hydraulic experimental campaign.
Sometimes, cleaning is recommended not only for a specific component but also
for the whole facility. In this case, cleaning of the whole facility can be performed by
