CUSTOMER: Nuclear Electric, Sizewell B Nuclear Power Station

PROBLEM: Accurate and reliable valve testing was required in quick time as part of the pre-commissioning process.

SOLUTION: Following an extensive series of trials, the outstanding performance of Trevitest convinced Nuclear Electric to use the system in the Pre-commissioning of Sizewell “B”. The tests on both pressuriser safety valves and main steam safety valves produced results that were always better than +/- 1%.

Testing Timescales
The Furmanite team, working closely with Nuclear Electric, had a tight timeframe to test the first twenty main steam safety valves. Two teams working twelve-hour shifts back-to-back undertook the testing.

OUTCOME: Within 36 hours the twenty valves had been tested.
