Framatome ANP replaces reactor vessel head at Daya Bay Unit 2

PARIS and LYNCHBURG, Va., April 11, 2003 — Framatome ANP, an AREVA and Siemens company, supplied a new reactor vessel head to the Daya Bay nuclear power plant in China and performed the replacement activities during a scheduled refueling outage at Daya Bay Unit 2.

The reactor vessel head was manufactured in Framatome ANP’s Chalon St Marcel factory and delivered to the site in December 2002. Guangdong Nuclear Power Joint Venture Company (GNPJVC), the owner of the nuclear power plant, decided to replace the reactor vessel head of Daya Bay unit 2 to take advantage of the new Alloy 690 offered by Framatome ANP.

The initial tight schedule for reactor vessel head equipment removal and reinstallation was reduced by 5 days, achieving a completion record of 10 days. The unit was back on line on March 19, 2003. A similar project will be carried out at Daya Bay unit 1 in 2004.

Due to the effective control of the radiological levels at the Daya Bay plant by Guangdong Nuclear Power Joint Venture Company (GNPJVC) and the efficiency of the operation, the total exposure was limited to 74 millisieverts (mSv), which is a 25 percent reduction in the levels normally measured for such an activity

This successful outcome results from the excellent cooperation between Framatome ANP, the Chinese maintenance company Shenzhen Nuclear Engineering (SNE), a subsidiary of 23rd Company, and Guangdong Nuclear Power Joint Venture Company.

Framatome ANP has been a longstanding contributor to the development of clean, cost-effective, nuclear generated electricity in China, beginning in 1986 with the signing of contracts to build the two Daya Bay 900 MWe units.
