3 China12 Plants under constructionAll Westinghouse AP1000 (Advanced Passive)50% less safety related valves80% less piping85% less cableHaiyang Site 6 reactorsSanmen Site 6 reactorsAbout 16,000 megawatts total
4 ChinaWestinghouse did a technology transfer to the Chinese for AP1000Signed contract with WestinghouseCannot market the AP1000 outside of ChinaScaled up the AP1000 to AP1400Marketing AP1400 outside of China
6 TaiwanLungmen Nuclear Power PlantGE ABWR (second built, first is in Japan, biggest nuclear plant in the world)2 units 1350 megawatts eachFuel load planned for April 2012(Unit 1)9.2 Billion USD (may never start)4 years behind schedule
8 Lungmen/GE valve spec specified stem mounted strain gages on all safety related MOVs Lungmen plant has 400 safety related valves200 per unitNo valve testing required prior to shipping valves to Taiwan
9 Westinghouse spec for valves in China included diagnostic testing prior to shipment For MOVFor AOVFor BOPThe spec was tailored for stem mounted strain gagesQSSSMARTSTEM
10 China / Taiwan Taiwan Waited to perform diagnostic testing Basically waited for US to do the researchThen wanted testing done for ½ priceTaiwanDoes lots of valve and actuator maintenanceBased on scheduleMaintenance work quality is poorUse incorrect greaseDon’t do many stem lubes
11 The first 4 units (2 at each of the China sites) big valves were procured by US valve companies FlowserveVelanWeirThe big contract went to FlowserveGatesGlobesMSIV
12 The remaining new plants in China Most valve contracts went to in country companiesShentong Valve (own Quiklook)SufaShenjiang Valve (will purchase)US companies bid but can’t competeValves built in China are low qualityUse cheap actuatorsThey don’t understand weaklinkRequired thrust determination is not standard

21 Taiwan Power Company Used ACE 3.0 Used ACETest Used Quiklook Teledyne awarded contract for AOV Program (Turn – Key)Design Basis CalculationsWeaklink AnalysisStatic TestingDynamic TestingUsed ACE 3.0Used ACETestUsed Quiklook
22 AOV Scope68 valves68 static tests6 dynamic testsTPC I/C StaffVery limited valve experienceDo not understand testingThey kept asking me about torque switch settings??
23 TPC is slowly adopting how we do business Just began using safety glasses/shoesUse pre-job briefsCalled TBMTool Box Meeting
25 First time TTS used Windows 7 for the Quiklook operating system XP software difficult to obtainFuture system will use Windows 7Discovered weakness with I/P circuitNew board is in Engineering
26 Valve population included 9 Fisher actuators25 Automax for quarter turn valves34 ValtekValves were very high marginMost valves have no regulatorsFull air pressureActuator nameplate indicated 100 psi maxMeasured 120 psi
