Introduction Testing Valves in Asia Fifth Annual QUIKLOOK Users Group Meeting
China • 12 Plants under construction • All Westinghouse AP1000 (Advanced Passive) • 50% less safety related valves • 80% less piping • 85% less cable • Haiyang Site 6 reactors • Sanmen Site 6 reactors • About 16,000 megawatts total
China • Westinghouse did a technology transfer to the Chinese for AP1000 • Signed contract with Westinghouse • Cannot market the AP1000 outside of China • Scaled up the AP1000 to AP1400 • Marketing AP1400 outside of China
Taiwan • Lungmen Nuclear Power Plant • GE ABWR (second built, first is in Japan, biggest nuclear plant in the world) • 2 units 1350 megawatts each • Fuel load planned for April 2012 (Unit 1) • 9.2 Billion USD (may never start) • 4 years behind schedule
Lungmen/GE valve spec specified stem mounted strain gages on all safety related MOVs • Lungmen plant has 400 safety related valves • 200 per unit • No valve testing required prior to shipping valves to Taiwan
Westinghouse spec for valves in China included diagnostic testing prior to shipment • For MOV • For AOV • For BOP • The spec was tailored for stem mounted strain gages • QSS • SMARTSTEM
China / Taiwan • Waited to perform diagnostic testing • Basically waited for US to do the research • Then wanted testing done for ½ price • Taiwan • Does lots of valve and actuator maintenance • Based on schedule • Maintenance work quality is poor • Use incorrect grease • Don’t do many stem lubes
The first 4 units (2 at each of the China sites) big valves were procured by US valve companies • Flowserve • Velan • Weir • The big contract went to Flowserve • Gates • Globes • MSIV
The remaining new plants in China • Most valve contracts went to in country companies • Shentong Valve (own Quiklook) • Sufa • Shenjiang Valve (will purchase) • US companies bid but can’t compete • Valves built in China are low quality • Use cheap actuators • They don’t understand weaklink • Required thrust determination is not standard
Roger and I hosted a seminar in China last year and invited: • Flowserve • Automatic Valve • Top Works • Curtis Wright (EGS connectors)
Teledyne has signed up a China Distributor • Chance Development (H.K.) Limited • They are pushing Quiklook/QSS in China • Company President is former Nuclear employee
Velan • Had Quiklook for a number of years • Flowserve • Bought Quiklook in 2009 • Weir • Bought Quiklook in 2010 • Taiwan Power • Using Quiklook since 1994
China Valves (AP1000) • All valve tested static and “DP” before shipping • 20 to 30 strokes required per valve • Reduced and nominal voltage • Actuator sizes are very conservative • All SR MOVs are DC • BOP all AC
Taiwan Power Company • Teledyne awarded contract for AOV Program (Turn – Key) • Design Basis Calculations • Weaklink Analysis • Static Testing • Dynamic Testing • Used ACE 3.0 • Used ACETest • Used Quiklook
AOV Scope • 68 valves • 68 static tests • 6 dynamic tests • TPC I/C Staff • Very limited valve experience • Do not understand testing • They kept asking me about torque switch settings??
TPC is slowly adopting how we do business • Just began using safety glasses/shoes • Use pre-job briefs • Called TBM • Tool Box Meeting
First time TTS used Windows 7 for the Quiklook operating system • XP software difficult to obtain • Future system will use Windows 7 • Discovered weakness with I/P circuit • New board is in Engineering
Valve population included • 9 Fisher actuators • 25 Automax for quarter turn valves • 34 Valtek • Valves were very high margin • Most valves have no regulators • Full air pressure • Actuator nameplate indicated 100 psi max • Measured 120 psi
