Control Rod Drive Mechanisms (CRDM)

More than 1,500 CRDMs have been successfully delivered and installed all over the world including 517 CRDMs for U.S. units.  MHI is the only company in the world to manufacturer both RVHs and CRDMs in-house by a single company.  This unique MHI capability has decreased overall schedule and project risk.  To date, of the 1,500 Mitsubishi replacement CRDMs installed in the industry, none have had any leakage issues.
