Fifth Annual QUIKLOOK Users Group Meeting
Introduction
Testing Valves in Asia
Stock options are overrated ….
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
Conceptual View AP1000
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
ABWR Reactor
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

36” MSIV Gate Valve
Taiwan Power Company– Teledyne awarded contract for AOV
Program (Turn – Key)• Design Basis Calculations• Weaklink Analysis• Static Testing• Dynamic Testing
Used ACE 3.0Used ACETestUsed 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/shoesUse pre-job briefs
– Called TBM– Tool Box Meeting
The TBM ….
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
Valve population included– 9 Fisher actuators– 25 Automax for quarter turn valves– 34 Valtek
Valves were very high marginMost valves have no regulatorsFull air pressure
– Actuator nameplate indicated 100 psi max– Measured 120 psi
