Boron Products LLC Awarded Contract for EPR Primary Coolant Additive

Ceradyne Boron Products, LLC, a wholly owned subsidiary of Ceradyne, Inc., announced a contract award of approximately USD 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 company expects to completely ship this order in the fiscal year ending December 31, 2011.

Boron Products, LLC operates the world's largest boron isotope separation facility providing enriched boron products for commercial nuclear power, defense, semiconductor and neutron detection applications. Enriched boron compounds are manufactured under an ISO 9001:2008 certified quality system and exceed nuclear safety and environmental regulatory guidelines. (07/2010)
