Turbine Testing: Proposal pricing includes
r ASME PTC 6 turbine Derformance testing. Following
discussion the prevailing approach is not to perform a full ASME PTC 6 performance test. Consideration is to
use the PTC 6 - 2004 Atemate Test. Key parameters will be megawatt output and reactor thermal. PE will
have high accuracy instruments for feedwater flow, main steam pressure, main steam RTD’s, condenser back
pressure and high accuracy megawatt meters. This approach will reduce the price by the amount included to
perform the full PTC 6.
Performance bonus / penalty clause should have a performance dead band. Review dollars tied to performance
testing result. The fact that the multiple changes to the plant will make exact megawatt contribution from a
single source difficult to evaluate. A deadband of +/- 0.7% (test accuracy) has been discussed as an amount to
account for these uncertainties and then a bonus could be considered for megawatts achieved above that value.
Siemens to review tbe following conceptslissnes:
Is replacement of the generator WTA voltane remlator required to support the 1200MVA generator rating
excitation requirements? WTA power amp drawers are uprated from 200 amps to 300 amps. Are the power
amp drawers fully redundant at 300 amps? Siemens to unbundle the Digital Voltage Regulator and price it
semrately. Provide basis for recommending the EM1 I RFI hardened cabinets. Verify the estimated cost for

return the-existing CR3 generator rotor back to Charlotte. The Shipping and Handling estimated cos~ate

Mammoat (bundled contract) for on site heavy hauling.
The final Secondary Plant design configuration must be provided to Siemens to support turbine blade path
design. This includes the MSR drains re-route and feed water heater specifications. Siemens to provide a date
when the information is needed for the final turbine steam path design.

Siemens will provide dehumidification for generator and no delays of high pot testing due to winding
moisture. Electrical Power required for generator core iron loop test wil be by PE.
