French reactor firm Framatome has completed instrumentation and control system work at Unit 3 of the Forsmark nuclear power plant in Sweden.
Framatome supplied a new neutron flux measuring system for the 1,170-MW unit, including installation and testing. The Forsmark nuclear facility, with an overall capacity of about 3,400 MW, is operated by Swedish utility Forsmarks Kraftgrupp AB, a subsidiary of Vattenfall.
The new instrumentation and control assemblies for the neutron flux wide-range monitoring system were designed and manufactured as modules. They were installed into the existing cabinets on site, according to Framatome.
The system monitors the neutron flux in the reactor core during downtime as well as plant start-up and shut-down operations, providing enhanced security measures.
Frederic Lelievre, senior executive vice president for sales, regional platforms of the instrumentation and control business at Framatome, said the Forsmark project was a success and showed the ability to provide upgrades to different reactor types globally.
Forsmark Unit 3 is a boiling water reactor. It began commercial operations in 1985 and is located on the east coast of Sweden about 100 kilometers (62 miles) north of Stockholm.
Altogether, Forsmark’s three units produce between 20 and 25 billion kWh or electricity every year, according to Vattenfall. It generates approximately 16 percent of Sweden’s total electricity consumption.
