Introduction

Testing Valves in Asia

Fifth Annual QUIKLOOK Users Group Meeting

slide3
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
slide4
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
slide6
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
slide8
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
slide9
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
slide10
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
slide11
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
slide12
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
slide13
Roger and I hosted a seminar in China last year and invited:
    • Flowserve
    • Automatic Valve
    • Top Works
    • Curtis Wright (EGS connectors)
slide15
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
slide16
Velan
    • Had Quiklook for a number of years
  • Flowserve
    • Bought Quiklook in 2009
  • Weir
    • Bought Quiklook in 2010
  • Taiwan Power
    • Using Quiklook since 1994
slide17
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
slide21
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
slide22
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??
slide23
TPC is slowly adopting how we do business
  • Just began using safety glasses/shoes
  • Use pre-job briefs
    • Called TBM
    • Tool Box Meeting
slide25
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
slide26
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
