Webatmosphere. It is preferable to maintain the suppression pool basic (pH > 7) so that the iodine remains in a more soluble form as CsI . Most licensees of BWRs have designated the SLC system as the system that will be used to maintain the water in the suppression pool basic. This new function for SLC is an accident mitigation function. WebFor short-term analysis, three kinds of LOCA scenarios were investigated: the recirculation line break (RCLB), the main steam line break (MSLB), and the feedwater line break …
