ROSEMEAD, Calif., Sept. 4, 2013 — Southern California Edison (SCE) today opened the San Onofre Digital Document Library at The library makes public key documents related to the design of the replacement steam generators, whose malfunction resulted in the shutdown of the San Onofre Nuclear Generating Station.

“The San Onofre Digital Document Library will help the public, elected officials and regulators better understand the history of the replacement steam generators that led to San Onofre’s closure,” said Ron Litzinger, president of SCE. “It is vitally important that we all achieve a full understanding of the facts so that future decisions by regulators and legislators are based on transparency and the highest quality information.”

The closure of the San Onofre nuclear plant earlier this year was the result of the failure of the plant’s replacement steam generators, which were designed and manufactured by Mitsubishi Heavy Industries (MHI). SCE previously announced that it had commenced the process of pursuing legal action against MHI to recover compensation for damages caused by the failure of MHI’s steam generators.

The San Onofre Digital Document Library contains a wide variety of documents, many made public for the first time. In total, the library contains nearly 100 documents, comprising more than 3,200 pages. The library supplements the numerous documents related to the replacement steam generators that SCE had previously made publicly available at

Some of the documents included in the library are partially redacted. The redactions were made because MHI has asserted that the redacted sections contain proprietary information that cannot be made public. SCE has asked MHI to agree that unredacted versions of these documents can be made public. SCE is planning to include additional documents in the library, and is asking MHI to confirm that these additional documents can be placed in the library without redaction.
