TEPCO proposes spent nuclear fuel storage facilities in Mutsu



TOKYO, April 11 (Kyodo) - Tokyo Electric Power Co. (TEPCO) on Friday 

presented a plan to Mayor Masashi Sugiyama of Mutsu, Aomori 

Prefecture, to build storage facilities to hold up to 6,000 tons of 

spent nuclear fuel in the city, TEPCO officials said.



The plan calls for the construction of two facilities near Sekinehama 

port in Mutsu, each capable of holding 3,000 tons of spent nuclear 

fuel for 50 years until the fuel is removed for reprocessing.



TEPCO hopes to have the first of the two facilities in service by 

2010 before building the second one. The construction cost for the 

whole project would be about 100 billion yen, according to the 

officials.



''We will decide whether to approve the site based on conclusions 

from the city assembly and residents,'' Sugiyama said.



Initially, the city considered limiting the storage to spent fuel 

from TEPCO, but in February, it was approached by TEPCO about storing 

spent fuel of other electric power companies at the facilities.



TEPCO will store about 4,000 tons of its own spent fuel at the 

facilities, with the remaining capacity expected to be shared with 

one to two other companies, the company officials said.



Japan Atomic Power Co. has already requested joint use of the storage 

and TEPCO is expecting participation from Sendai-based Tohoku 

Electric Power Co., according to the officials.



If the city approves the plan, TEPCO and participating power 

companies would set up a business unit to build and operate the 

facilities, the officials said.



TEPCO told the Mutsu city government on April 3 that a study it 

conducted at the proposed site showed that construction of the 

storage facilities there is technically feasible.

Framatome ANP Replaces Reactor Vessel Head at Daya Bay Unit 2 Nuclear 

Power Plant in Record Time



PARIS and LYNCHBURG, Va., April 10 /PRNewswire/ --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.
