PITTSBURGH, April 17 /PRNewswire/ -- Westinghouse Electric Company has
won a contract to provide two DMIMS-DX(TM) Digital Metal Impact Monitoring
Systems at Fortum Corporation's Loviisa Nuclear Power Plant Units 1 & 2 in
Loviisa, Finland. The units are pressurized water reactors of VVER design.
The systems will be delivered in August 2007 and installed during the fall
2007 outages.
Westinghouse DMIMS-DX(TM) systems are installed at Millstone 3, Krsko,
Diablo Canyon 1 & 2, Wolf Creek, and Beaver Valley 1, which are all
Westinghouse NSSS plants, and at Crystal River 3, which is a B&W plant. In
addition, the DMIMS-DX(TM) systems are scheduled to be installed at Vogtle
1 & 2 in May 2007.
DMIMS-DX(TM) provides fast, reliable detection of loose part impacts
within the Reactor Coolant System (RCS), while minimizing the generation of
false alarms. This monitoring system is a greatly enhanced version of the
previous Westinghouse DMIMS system, employing the latest digital technology
and offering significant operational advantages to our customers.
Loose parts monitoring is based on listening for the impact of loose
parts against fixed components within the primary system as they are
propelled by the coolant flow. This application appears simple on the
surface, but its effective implementation is not an easy task. The noises
typical of an operating plant can generate false alarms that reduce
operator confidence, interfere with normal operations, and cause
unnecessary expense. The Westinghouse DMIMS System uses a patented
algorithm to determine the metallic characteristics typical of loose parts.
This algorithm and the associated alarm algorithms, together, minimize the
generation of false alarms and have established a reputation for
reliability within the industry.
Westinghouse, a group company of Toshiba Corporation, is the world's
pioneering nuclear power company and is a leading supplier of nuclear plant
products and technologies to utilities throughout the world. Westinghouse
technology today is the basis for approximately one-half of the world's
operating nuclear plants, including 60 percent of those in the United
States.
