Mitsubishi Nuclear Energy Systems Inc. Key Developments

Mitsubishi Heavy Industries Ltd. and Mitsubishi Nuclear Energy Systems Inc. to Defend $4 billion Claim over US Nuke Plant

Southern California Edison and its subsidiary Edison Material Supply are asking for arbitration over the claim against Mitsubishi and its wholly-owned US subsidiary Mitsubishi Nuclear Energy System. The original dispute, first raised in July, reported that SCE had to close San Onofre Nuclear Generating Station because replacement steam generators supplied by Mitsubishi were defective. The arbitration, intended to avoid a court battle, is being sought because the two sides have so far failed to reach agreement. Through the arbitration process, Mitsubishi decided to aggressively defend itself by accurately representing the facts involved and the applicable legal principles. At the same time, Mitsubishi will take actions for its counterclaims because it has been damaged by inappropriate actions by SCE.

Edison Files Notice of Dispute with Mitsubishi Heavy Industries of Japan

Southern California Edison Co. has started legal action against the manufacturer of steam generators that failed and forced the permanent closure in June of the San Onofre nuclear power plant on the northern San Diego County coast. The electric utility filed a formal notice of dispute with Mitsubishi Heavy Industries of Japan and its United States subsidiary, Mitsubishi Nuclear Energy Systems. The action sets in motion negotiations that involve finding fault and assessing financial damages.
