$this->bbcode_second_pass_quote('', '[')b]Sweden Approves Power Uprates For Ringhals
The Swedish government has approved power uprates for units one and three of the Ringhals nuclear power plant, as well as the relincensing of unit two, it has been confirmed.
In a statement on 20th October 2005, the government said Ringhals plans to uprate the two units by a combined total of 200 megawatts (MW). Ringhals-1 is an 830 MW boiling water reactor that began commercial operation in 1976. Ringhals-3, a 915 MW pressurised water reactor, began commercial operation in 1981.
Ringhals was the first of the Swedish nuclear licensees to apply for increased power in its reactors. The Swedish government is also due to make a decision on uprate applications from Forsmarks Kraftgrupp AB, for all three reactors Forsmark nuclear power plant, and OKG AB, for unit three of the Oskarshamn plant (see also News in Brief No. 39, 11th October 2004 and News in Brief No. 81, 13th September 2005).
An environmental court reviewing Ringhals’ environmental impact statement asked the government in May 2005 to consider the uprates and the relicensing. The court decided the issues were of such significance that, by law, the government should make the decision (see News in Brief No. 53, 11th May 2005).

Site preparation work has begun for the construction of a mixed oxide (MOX) fuel fabrication facility that will convert surplus weapons-grade plutonium into MOX fuel for use in commercial nuclear power plants.
The facility, at Savannah River in South Carolina, will be an integral part of the National Nuclear Security Administration's (NNSA) plutonium disposition programme. It will convert weapons-grade plutonium into MOX fuel for use in power plants operated by US utility Duke Power. Duke operates the Catawba and Oconee nuclear power plants in South Carolina, and the McGuire plant in North Carolina.
The NNSA's plutonium disposition programme aims to eliminate a total of 68 tonnes of surplus weapon-grade plutonium both in the US and in Russia, and is based on a 2000 nonproliferation agreement between the two countries. Both countries will dispose of their plutonium by converting it to MOX fuel. Once the MOX fuel has been irradiated, the plutonium can no longer be readily used for nuclear weapons.
At a 17th October 2005 ceremony to mark the start of site preparation work, NNSA administrator Linton Brooks said the MOX facility will create hundreds of new jobs at the DOE’s Savannah River site and will provide “a pathway out of South Carolina” for plutonium brought there for disposition.
The facility will be built by DOE contractor Duke Cogema Stone & Webster, and owned by the NNSA, a semi-autonomous agency within the DOE. The US Nuclear Regulatory Commission approved the facility in March 2005 following an application submitted in 2001 (see News in Brief No. 56, 1st April 2005).
In May 2005, Duke Power announced that four MOX fuel lead assemblies it planned to test at its Catawba plant had arrived from France (see News in Brief No. 51, 5th May 2005).
