NUCLEAR POWER


DISMANTLING PLAN FOR SOVIET-ERA REACTORS T


he consortium comprising Westinghouse Electric Spain, Jacobs and the Lithuanian Energy Institute was selected to plan dismantling and waste management at the Ignalina Nuclear Power Plant (INPP) in Lithuania. Soviet-designed Ignalina could be


the first graphite-moderated reactor plant to be dismantled, making it an important test bed for methodologies that could be used to decommission the UK’s Magnox and advanced gas- cooled reactors, which also have graphite cores. “This project, on top of the recently announced contract with Norsk Nukleær Dekommisjonering, has advanced Jacobs’ strategy to grow our decommissioning and regeneration


solutions business in continental Europe,” said Jacobs Energy, Security & Technology Senior Vice President Karen Wiemelt. “Our teams based in the UK, France and Slovakia are applying decommissioning skills acquired through work on some of the world’s most complex and challenging nuclear sites including Sellafield and Fukushima.” In 2002, the Lithuanian government


decided to shut down Ignalina NPP, which supplied up to 88% of the country’s electricity. Over the next 19 years, Jacobs formed part of the project management unit for a set of purpose- built facilities needed to decommission


the plant, as part of a programme led by the Ignalina International Decommissioning Support Fund and financed through the European Bank for Reconstruction and Development. ●

FLOW OR LEAK DETECTION IN NUCLEAR POWER PLANTS rocess and plant engineers


alarms and indicators for use in P


liquid, air, gas, or for interface service will find the FLT93 series FlexSwitch from Fluid Components International (FCI) provides a highly reliable solution.


The FCI FLT93 FlexSwitch provides dependable critical equipment protection and plant integrity validation that makes it Ideal for use in a


wide range of nuclear power plant flow,


level and temperature


measurement applications. Applications include: reactor core coolant, level interface detection and temperature, pump protection, flood alarm, condensate pot level and turbine water level.


It is ideal


in any application where the measurement of both


responsible for nuclear power plants who need various


flow and temperature or level and temperature are important.


A single sensor design provides dual measuring functions with the FLT93 FlexSwitch. It helps nuclear plant operations save weight, space and costs over two or more discrete sensors. Operators also realise reduced qualification installation costs and complexity. Its multi-parameter


measurement design is based on more than 55 years of flow and level switch engineering and application


experience, providing a rugged long-life instrument.


The original FCI models 12-64 and FR72 were installed when the first commercial nuclear


power plants were built and are just now being replaced by the FLT93 series. They have survived the initial operating licenses and are only now being replaced due to the extensions being granted.


The FLT93 FlexSwitch has been


tested to IEEE 323-1983 and IEEE 344-1987, making it fully qualified for Class 1E safety related nuclear power plant applications. FCI maintains a 10CFR50 Appendix B Quality Assurance Programme and complies with 10CFR21 and ANSI-N45-2. Both the insertion and in-line sensor versions are qualified


for a 40-year life at


150°F. The FLT93 sensor is qualified to radiation levels of 2x108 rads. The FLT93 electronics are qualified to 5x105 rads for applications requiring an integral unit (sensor and electronics). As a dual-function instrument,


the new product can be configured for flow or level sensing, flow + temperature sensing or level + temperature sensing. A single FLT93 FlexSwitch measures and monitors flow or level and temperature simultaneously with excellent accuracy and reliability. ●
