Ceradyne Receives Order for B-10 Enriched Boric Acid from EDF

Ceradyne Boron Products, LLC ("Boron Products, LLC"), a wholly owned subsidiary of Ceradyne, Inc. (Nasdaq:CRDN), is pleased to announce a contract award of approximately $8 million for the supply of B-10 Enriched Boric Acid to Electricité de France SA (EDF) for its first European Pressurized Reactor (EPR) presently under construction in France.

Enriched Boric Acid is designed into the EPR as the primary coolant additive for rate of reaction control. Isotopically enriched boric acid increases criticality control, achieves higher levels of long-term control, reduces the corrosion effect and reduces operator exposure to radiation.

“The utilization of advanced reactor designs in conjunction with superior safety and operating systems ushers in a more efficient, safe, reliable and environmentally friendly energy alternative to greenhouse-gas emitting technologies," said Dennis Manning, Vice President and General Manager. "Boron Products, LLC is proud to be involved in the success and continued advancement of safe, reliable nuclear power generation. We expect to completely ship this order in the fiscal year ending December 31, 2011.”
